Allow me to introduce you to one of my all-time favorite side dishes.

I’m not kidding. I make this one all. the. time.

It’s my favorite when I’m craving something salty and sweet. It is uber-fast to prep. It only calls for a few ingredients. It is easily customizable to different seasonings to pair with your main course. It’s pretty healthy. And…it’s ridiculously delicious.

Have I convinced you yet? (I think I’ve convinced myself. Already hungry for the leftovers!)  :)

Description

You will love this yummy Roasted Sweet Potatoes & Onions recipe. It’s sweet, onion-y and incredibly delicious.


Ingredients

Scale
  • 2 sweet potatoes, sliced into 1/8-inch thick coins
  • 1 onion, quartered then cut into 1/2-inch slices
  • 2 Tbsp. vegetable or canola oil
  • 1/2 tsp. sea salt (or more or less to taste)lots of freshly ground black pepper
  • optional: additional seasonings such as Italian (store-bought or homemade)


Instructions

  1. Preheat oven to 400 degrees.
  2. Combine all ingredients in a large bowl. Toss with a spoon until vegetables are evenly-coated.
  3. Prepare a baking sheet with aluminum foil or parchment paper, and spray with cooking spray. Transfer vegetables to the baking sheet, and spread so that they are evenly spaced in a single layer. (I crammed a few too many in the photo above, which doesn’t let them get quite as crispy.) Bake for 20-30 minutes, or until onions begin to crisp and brown, and sweet potatoes are cooked through.

Notes

To be honest, even though I have seasoned these a zillion ways over the years, the classic salt-and-pepper combo is still my favorite.  But here are some other fun variations to choose from:

  • toss with a tablespoon of balsamic vinegar (when tossing with the olive oil)
  • toss with various seasonings before roasting
    • Italian seasonings (oregano, thyme, parsley, rosemary, etc.)
    • smoked paprika
    • chipotle and/or chile powder and cumin
  • after roasting, top with…
    • chopped fresh parsley
    • toasted slivered almonds
    • freshly-grated Parmesan

    Have discovered this does not work as well with red onions; will revert to brown.

  2. Airy says:

    Great recipe, easy to follow, thoroughly enjoyed it. A bowl of this is a meal (maybe with an added protein like a poached egg) in itself.

    Always make this for Thanksgiving.

  4. Eva P Koeper says:

    I made this recipe but added smoked sausage sliced a 1/4 inch thick. I cooked this on a large skillet on top of the stove until the potatoes were tender and the sausage browned. Delicious!

      We’re glad you enjoyed it, Eva!

    Hah, leftovers! Made extra, none left for leftovers. Awesome recipe, did not have any balsamic so after the salt and pepper I used some Worcestershire sauce. Just enough to give an extra bit of flavour. Again, an awesome dish.
    On a side note I am not a huge fan of sweet potatoes, but after making this last night, I would like to make another batch for tonight.

    THESE ARE FANTASTIC. I am doing my sunday food prep for the week and decided to give these a try- and I am so glad I did!! Just the right amount of crispy and soft, and filled my condo with an amazing aroma. I followed the recipe, except had only half a white onion and half of a red onion so I used both. I was also out of pepper (almost never happens) so I used a pepper steak seasoning instead of salt/pepper. MMMM
