This Vegetarian Portobello Pot Roast recipe can be made easily in the slow cooker or Instant Pot (pressure cooker). And it’s SO hearty and comforting and delicious!
As a Midwestern girl through and through, I’ve gotta admit — I will always love me a good pot roast.
But hey, whoever said that had to include roast beef? 😏
A few weeks ago, when I found myself with two leftover cartons of baby bella mushrooms in the fridge that needed to be used up stat, I decided to try swapping them in as the main ingredient in my traditional pot roast recipe. And lo and behold, they turned out to be a plant-based swap made in heaven.
This vegetarian pot roast recipe was a total winner, guys!
It’s still full of those classic savory flavors (and garlicky gravy!) that we all love. It’s quick and easy to prep, and easy to make either on the stovetop or in the slow cooker or Instant Pot. It’s naturally vegetarian, vegan, and gluten-free. And it’s totally, wonderfully delicious.
My kind of comfort food. 💛
To make the recipe, start by gathering lots of your starring ingredient — portobello mushrooms. 💛 You’re welcome to use full-size portobellos if you’d like. Or, you can be like me and just use a few cartons of baby bellas. Chop them up into bite-sized pieces…
…then combine them in a slow cooker or pressure cooker, along with some potatoes, carrots, pearl onions, garlic, and all of the ingredients for that classic savory gravy. Cook until the potatoes are nice and tender. Then for a final step, thicken that gravy up a notch…
…and voila! This delicious veggie-filled mushroom pot roast will be yours to serve and enjoy!
I went old-school and served mine over some egg noodles, but some grains or rice would also work well here. I served mine up with this simple salad and some red wine, and the meal was perfection. 🌟🌟🌟
