This easy Green Bean Casserole recipe is made 100% from scratch with lightened-up ingredients, including a delicious creamy green bean filling and crispy onion topping. It’s also easy to make ahead and always a crowd fave.
Move over, canned creamy soup, frozen green beans, and packaged fried onions.
This modern homemade green bean casserole recipe is made entirely from scratch and tastes a million times better than the retro casserole full of processed ingredients. And it is my hands-down fave. ♡♡♡
For too many years, I always passed on the green bean casserole at Thanksgiving because it was so mushy, bland and boring. But as it turns out, when homemade green bean casserole is well-seasoned and made with better ingredients, it comes to life and tastes SO fresh and flavorful. And it’s still quite simple to make!
Instead of soggy frozen green beans, fresh green beans are the star of the show here, which are ever-so-briefly cooked in order to preserve their crisp texture and bright flavor. Instead of canned cream of mushroom soup, fresh mushrooms are sautéed and folded into a lightened-up creamy Alfredo sauce. And instead of dry, packaged, palm-oil-fried onions, fresh red onion is sautéed with crispy panko breadcrumbs, which toast to golden perfection as the casserole bakes.
Together, all of these ingredients combine to make a casserole that is legit delicious and anything but boring. I make it every Thanksgiving, and friends and family all agree that it’s the best!
Green Bean Casserole Recipe | 1-Minute Video
Best Green Bean Casserole Ingredients
Alright, so before we get to the full recipe below, let’s talk for a sec about about the best green bean casserole ingredients. The three components for this recipe include…
Green beans: I really recommend using fresh green beans (vs frozen) for optimal crispiness, cut into bite-sized pieces with the ends trimmed off and discarded.
Crispy onion topping: By contrast to the retro French’s green bean casserole recipe, we will make our French “fried” onion topping here from scratch. All you need are some very thinly-sliced onions (red, white or yellow — up to you), Panko breadcrumbs (which we will briefly sauté to make them extra crispy), Parmesan cheese, butter and salt.
Mushroom Alfredo sauce: Made with fresh baby bella mushrooms (or your favorite kind of mushrooms), lots of garlic, butter, flour, stock, milk, Parmesan, salt and pepper.
Green Bean Casserole Tips
Full instructions are included in the recipe below for how to make green bean casserole, but here are a few key tips to remember:
Don’t overcook the green beans: Remember when you are blanching the green beans that they will continue to cook and soften while baking in the oven with the rest of the casserole. So it’s important to undercook them slightly during this first step so that they don’t get mushy in the oven. (I like my beans pretty crispy so I usually boil mine for about 2 minutes.)
Pre-toast the breadcrumbs: In order for the Panko breadcrumbs to get extra crispy and golden, it helps to sauté them briefly in a bit of butter before baking them in the oven.
Very thinly slice the red onion: I also recommend slicing the onion as thinly as possible so that it can crisp up well in the oven.
Feel free to make the casserole ahead of time: If you would like to prep the casserole ahead of time (very helpful for Thanksgiving), just follow the recipe instructions through the end of Step 5. Then instead of placing the baking dish in the oven, cover it tightly with foil or plastic wrap and refrigerate for up to 48 hours. Once you are ready to bake the casserole, uncover and bake as directed.
Optional Variations
There are many different ways that you can customize this fresh green bean casserole recipe to your liking. For example, feel free to…
Make it vegan. To make vegan green bean casserole, use olive oil or vegan butter (in place of butter) and plain plant-based milk (instead of cow’s milk). Then you can either omit the Parmesan altogether, sub vegan cheese in its place, or sprinkle in some nutritional yeast to taste.
Add bacon. I mean, I’m never going to turn down a green bean casserole with bacon. ;) Feel free to dice and fry up some bacon to add to this casserole if you would like. And for extra flavor, use the leftover bacon grease to sauté the onions and mushrooms.
Add in extra cheese. To make extra cheesy green bean casserole, feel free to stir some cheese (such as smoked gouda, cheddar, feta, blue or goat cheese) into the green bean filling.
Add Cajun seasoning. I also really love adding in a few teaspoons of Cajun seasoning (or Old Bay seasoning) to the Alfredo sauce too. It adds a nice extra kick, and pairs well with all of the other flavors in this casserole.
Add some heat. Want to add a little heat to this casserole? I love adding a finely-diced jalapeño to the onion topping. Or you can just sprinkle some crushed red pepper flakes into the mushroom sauce.
Many of you have also asked in the past for a CrockPot green bean casserole recipe. And unfortunately, I just don’t think that this one translates very well to the slow cooker. (The cream sauce needs to be cooked on the stove, and the onion topping really needs to be crisped up in the oven.) So I vote go the traditional route with this one.

This easy Green Bean Casserole recipe is made from scratch with lightened-up ingredients, it’s nice and fresh and crispy, and it is full of the absolute best flavors. Always a crowd fave!
Ingredients
Scale
Green Bean Casserole Ingredients:
2 pounds fresh green beans, trimmed and cut into bite-sized pieces
1/4 teaspooneach fine sea salt and freshly-cracked black pepper
Mushroom Alfredo Sauce Ingredients:
2 tablespoons butter or olive oil
8 ounces baby bella mushrooms, thinly sliced
4 cloves garlic, pressed or minced
3 tablespoons all-purpose flour
1/2 cup vegetable stock
1 cup milk (I used 2%, but any milk will do)
1/2 cup freshly-grated Parmesan cheese
1/2 teaspoon fine sea salt
1/4 teaspoon freshly-ground black pepper
Instructions
Preheat oven. Heat oven to 375°F.
Trim, cut and briefly boil the green beans. Heat a large stockpot of water over high-heat until boiling. Meanwhile, trim and cut the green beans. Then add the beans to the boiling water and cook for 2-3 minutes, depending on how crispy you like your green beans. (Keep in mind that the beans will cook more in the oven, so err on the side of undercooking them to your taste during this step.) Then use a slotted spoon or large strainer to transfer the beans immediately into a large bowl of ice water, and give them a quick stir. This will prevent them from cooking longer. Set aside.
Prepare your crispy onion topping. Melt 1/2 tablespoon butter (or olive oil) in a large sauté pan over medium-high heat. Add the onion and sauté for 2-3 minutes, stirring occasionally, until the onion is partially cooked but still holds its shape. (You don’t want the onion to get too soft.) Transfer the onion to a clean bowl. Add the remaining 1/2 tablespoon butter to the sauté pan, along with the panko, and stir to combine. Cook for 2-3 minutes, stirring constantly, until the panko is lightly golden. Remove from heat, and transfer the panko to the bowl with the onions. Add in the Parmesan, salt and pepper, and toss the onion mixture until evenly combined. Set aside.
Prepare your mushroom alfredo sauce. Briefly rinse and dry the sauté pan. Then return it to the stove. Melt the butter over medium-high heat. Then add the mushrooms and sauté for 5 minutes, stirring occasionally, until lightly browned and soft. Add the garlic and sauté for 1-2 more minutes, stirring occasionally, until fragrant. Stir in the flour and sauté for 1 more minute, stirring occasionally. Then add in the vegetable stock, and stir until the flour is evenly dissolved. Add the milk and Parmesan, and stir to combine. Continue cooking the sauce until it reaches a simmer and thickens. Then remove from heat, and season with salt and pepper to taste.
Put it all together! Combine the green beans and mushroom alfredo sauce in the stockpot, and stir the green bean mixture until evenly combined. Transfer to a 9 x 13-inch baking dish, and spread the green bean mixture out in an even layer. Sprinkle evenly with the crispy onion topping mixture.
Bake. Then bake for about 25 minutes, or until the crispy onion topping is golden and crispy. (Keep an eye on it so that it does not burn. If it does start to char, simply lay a piece of aluminum foil on top of the casserole.)
Serve warm. Remove from the oven and serve warm, garnished with extra freshly-cracked black pepper (plus maybe some parsley) if you’d like.
Make-ahead instructions: Follow the recipe through the end of Step 5. Then instead of placing the baking dish in the oven, cover it tightly with foil or plastic wrap and refrigerate for up to 48 hours. Once you are ready to bake the casserole, uncover and bake as directed.
Storage instructions: If you have leftovers after the casserole has already been baked, just refrigerate them in an airtight container for up to 3 days. (Unfortunately the Alfredo sauce does not freeze well, so I do not recommend freezing this casserole.)
This has been a favorite of mine since I made it three years ago. My office loves it and I just brought it to friendsgiving last night and got a lot of comments like, “why does this taste so much better than what my mom makes?” and “omg this is so good.” I won’t ever go back to the OG version. This takes the cake.
I absolutely love it! I pass on the other way as well and have made one from the Spark People Cookbook that uses fresh green bans too but no Parmesan cheese. I will try yours out.
Late to the party here on this post – but I’m totally making this version this year!! Would you happen to have the nutritional breakdown for this? I’m just wondering before I spend an hour piecing all together :P
OH MY GOD the green bean casserole was amazing. The Alfredo mushroom sauce is to die for. No leftovers and my kids want it again tonight. Go figure kids asking for more green beans.
I made this last week, and it was FABULOUS! I was a little nervous because I’m not a fan of the “traditional” green bean casserole, but man… this was amazing. I followed the directions to add bacon and prep ahead of time. This will definitely be added to the Thanksgiving (and other meal!) rotation.
Tested this out the other day for Thanksgiving and it’s delicious! Definitely bringing it to dinner tomorrow. I did the “regular” version but like all of the variation options.
I made this for Thanksgiving and for Christmas dinners. Everyone loved it! The day before I blanched the green beans and made the mushroom alfredo sauce, combined, put in a 9×13 pan, covered and put in the frig. The day of, I made the crunchy onion topping. I added about 10-15 minutes extra cooking time and covered towards the end to keep the onions from browning too much.
i tried this recipe tonight and it was great! the only thing i did differently was i roasted the green beans with the sliced mushrooms, saved time and gave the vegetables a nice carmelized flavor. i tossed them with olive oil and worcheshire sauce.
The flavors were wonderful but my green beans were a little undercooked even with following the directions exactly. Inwipp cook longer next time and this will be perfect! Everyone LOVED the topping. Such great flavor combos. Thanks you for the recipe.
Made this with my 4 year old. She loved the onion topping and was snacking on it as I was making the mushroom part. Never had green bean casserole but dislike canned mushroom soup so I tried this recipe. It was FANTASTIC! Every part snelled and tasted great. I had to hold back eating it so it could all come together as a casserole. Worth the wait! Saving for future use. Thanks
I’m excited to stumble upon your website as I again seek to add more vegetarian meals to our meat eating household. Do you by chance post the nutritional information for your recipes. Then I can see how much protein I’m getting / sodium or sugar? Thank you.
This was terrific! My family liked this SO much more than the mush we normally have! The onions on top add another dimension and the homemade mushroom sauce is so tasty.
Next time I’ll make half for our family of 6 as we had a lot of leftovers. (Boys are teens & young 20s and we had an entire quart left over) Definitely will be making a full batch for a gathering of friends over the holidays.
I’ve made this recipe a couple of times and love it! Definitely tastes better than the original, canned kind (yuck). I’m looking to make it again this year but need it to be dairy free. Have you tried substituting almond milk or coconut milk?
Ali, I’m on a restricted paleo diet so don’t use panko bread crumbs. Maybe I can use a combination of flax seeds and almond flour? But how to prepare it is beyond me. Can you suggest a good alternative?
Like a few other commenters, my casserole was underdone after 30 min in the oven – I’d also kept my beans in the boiling water for 5 min. The recipe makes a lot, there was about 25% left over after an 8-adult dinner party. I’m planning to make this next week for family Thanksgiving, but will cut the recipe in half and cook longer. I added Thyme into the mushroom alfredo for more flavor.
I made this for the first time and it was delicious. It was so much better than the usual mushy green bean recipe I make. All my family loved it and I could have made so much more because everyone wanted seconds of it. I’ll be making this again soon. It’s definitely a keeper.
I’ve made this recipe on this past Thanksgiving and everyone in my family loved it! The best part is that no one noticed that I used turkey bacon, it turned out incredible delicious. I will make it again for Christmas. Thanks for such great recipe.
This looks ideal! I hope to make it next year for Thanksgiving – I wish I’d seen it in time for this year’s one. You are so right in your description of the traditional processed version as being “mushy”. That is one of the things I really don’t like about the old-style processed version. There’s enough pureed/mashed foods at Thanksgiving as it is (mashed potatoes, gravy, which I love but….. the rest of it needs to have other textures!)
So, am looking forward to making this fresh, from-scratch green bean casserole. I’ll be making the Alfredo Sauce before that though – I’ve been looking for a regular from-scratch Alfredo Sauce recipe. I’m planning to make turkey alfredo with leftover turkey. I usually use jar alfredo sauce from the store, but it just tastes artificial. So, thank you for a from-scratch alfredo sauce recipe at a time that I’m needing it. Bookmarking this page.
I’m excited to try this but feel frustrated that when selecting the option to print, the format wants to include the video Ads and makes the Recipe To direction formatting all separated. The ingredients are a whole section away from the directions because there’s a large video ad included. I haven’t had any issues like this in the past with your other recipes. Is there a way to fix it? The recipes with all the links,videos and items is over 4 pages. Is this just my error? Idk!

Very nice. Didn’t have the fixings for the Alfredo sauce so dumped in a can of Cream of Mushroom soup onto the sauteed mushrooms, and had to use regular breadcrumbs because I was out of panko, but still came out great. I really like the DIY onion topping idea. Have made the casserole with fresh mushrooms & beans but never with the right topping before. Two thumbs up.
Amazing recipe! The best green bean casserole I have ever had. I added 1/2 cup of dry white wine and some dry herbs (basil, thyme, parsley etc.) into the the mushroom Alfredo sauce to enhance the flavor. I can’t wait to make it again. Thanks for this great recipe.
This recipe is really good!! All the flavours meld together to make it one tasty dish!! I hadn’t used Panko crumbs before and was really impressed with them.
I made 1/2 a recipe and followed the directions – which were excellent. I didn’t think there would be enough alfredo sauce for the beans but it cooked up beautifully. I slice the red onion on my mandolin. It made the job so much easier.
Haven’t Baked it yet but I can already tell this is going to be a favorite holiday dish from here on out. There’s only 4 of us so don’t judge, but one person doesn’t like onions so we’re going with two 12×9 shallow foil baking pans. One has extra Parmesan and panko topping and the other is prepared as the recipe states. I also chopped up and browned some high quality Black Forest bacon pieces and tossed them in after mixing the green beans and Alfredo sauce together so the bacon stays crispy. I tasted the mushroom Alfredo sauce after stirring the bacon in and it’s heavenly. All prepped in the foil pans and ready to bake tomorrow. Can’t wait!!!
Just put it in the oven. The Alfredo sauce is magnificent. I added sine cayenne pepper for a little heat. I can’t wait to try it, I think I just found my signature dish ❤❤
Loved this recipe! We’ve tried other “clean” green bean casseroles in the past and they were always disappointing. Not this one! We made it gluten free by subbing gluten free breadcrumbs and 1 to 1 gluten free flour. We also used cashew milk in the sauce. Delicious!
This was amazing and a huge hit at Thanksgiving. I saw a lot of people had said that the green beans were still not done – I cooked them for 5 mins and actually would have liked them a bit crispier. So I think the recipe is spot on! I will never make the cream of mushroom soup version again:)
Wow! Just made this for post Thanksgiving birthday and it was such a big hit. I grew up with the older processed version and avoided it like the plague fir the last 35 years, but with this amazing version, it is BACK on the menu!! Bravo Ali!!
This version sounds amazing. We like our green beans crisp. So is it necessary to pre cook them? Would they be ok just rinsing and cutting up and then cooking them in the oven.?
Has anyone tried this without mushrooms? Looks delicious but we’re a household that doesn’t like mushrooms so wondering if I can just skip that step!
Melissa —
I used about 1/2 the mushrooms the recipe called for. Sauteed them and put them to the side before making the alfredo because we have some that don’t like mushrooms. Then I sauted the garlic and made the alfredo sauce. I mixed the sauce into the beans, put half in the baking dish. Then mixed the mushrooms in the remaining half and put it in the baking dish. Topped the casserole as detailed and baked. No complaints of mushroom flavor from those who don’t like them.
We’ve always liked a cheesy green bean casserole, so instead of parmesan in the alfredo sauce I used unexpectd cheddar from Trader Joes (it’s a cheddar with parm blended). We really liked it and will make this again.
I made this last year and it was fantastic. This year thinking of making it ahead. Has anyone made it ahead of time with success? My only concern is that the topping might get soggy. Has this happened for anyone or did it crisp up nicely?
I’m planning on making this recipe for Thanksgiving this year but I want to make it and bake it the day before. What’s the best way to reheat this in the oven?
This has been a favorite of mine since I made it three years ago. My office loves it and I just brought it to friendsgiving last night and got a lot of comments like, “why does this taste so much better than what my mom makes?” and “omg this is so good.” I won’t ever go back to the OG version.

I apologize in advance if this question has already been asked and answered but I do not see the calories for this dish.
We absolutely loved this! Sooo much better than the old Campbell’s soup version.
Can’t find calorie listed

Cette recette fera désormais partie de nos favorites! Idéal pour inciter à manger plus de légumes
Love it. That’s a bechamel not an alfredo, though.

a+
I would like to give this recipe a 10 if I could . Cannot wait to serve this.
This recipe makes green bean casserole so easy to make yet so delicious.

Only suggestion is (no one going to like it lol) use the Frenches onions

The Green Bean Casserole sounds sounds so good. I am going to make it for Thanksgiving.
I made this last year and it was fantastic. This year thinking of making it ahead. Has anyone made it ahead of time with success? My only concern is that the topping might get soggy. Has this happened for anyone or did it crisp up nicely?
I’m surely going to bake this one. ? Can you buy the fresh green beans now and freeze them?
I’m planning on making this recipe for Thanksgiving this year but I want to make it and bake it the day before. What’s the best way to reheat this in the oven?
Can you use shallots in place of the red onion for the topping?
Also, if you make this ahead of time, does the topping need to be refrigerated or is it safe to leave at room temperature?
For sure! And I would go ahead and refrigerate the topping too, just to be safe. It should crisp back up in the oven.
