Vegan Pressure Cooker Portobello Mushroom Fajita Bowls

Since starting to cook food for Luca, I’ve really been into my pressure cooker. It’s great for cooking spaghetti squash (which he loves) or just making super quick and easy meals, like today’s recipe.

When I’m in a pinch, I know I can just dump a bunch of ingredients into my pressure cooker, hit start, and within 20 minutes, a meal is prepared and I can do other things while it cooks (that’s the best part – your meal is cooking while you’re also being productive.)

I love using Portobello mushrooms as meat and carb alternatives – as burgers, as burger buns, as meat (have you made the Mushroom Bulgogi Bowls from my new cookbook?) – because they are so hearty!

These bowls are seasoned with my homemade fajita seasoning that brings the peppers, onions, and mushrooms to life – you won’t miss the meat!

You can serve these with brown rice instead, cauliflower rice if you prefer, OR you can ditch the bowl altogether and have them in taco shells!

Hope you’re having a wonderful Sunday – and tomorrow, I’ll be sharing my socca flatbread pizza! I guess it’s a meatless week!

  • Thanks for another pressure cooker recipe, especially a vegan one! This is my favorite way to cook right now and it’s great to have you as a resource!
  • Is there no added liquid? Just the juice from the diced tomatoes is enough? Otherwise this looks great! Can’t wait to try it.
    • Correct, no added liquid. The juice from the diced tomatoes is adequate. It actually turns out very juicy, I had to drain some liquid off so it wouldn’t be so soupy when I stored the leftovers. (The bell peppers release water naturally as well.)
  • Can these be made without a pressure cooker?
  • How do the leftovers hold up in the fridge for meal prep?
    • I drained off some of the liquid for leftovers/meal prep. This recipe is delicious and perfect for meal prep!
  • Look yummy! Can’t wait to try it.
