Make these amazing peppers and onions with your Instant Pot! These Instant Pot fajitas are ready in less than 5 minutes!
I love Mexican food and fajitas are no exception! I have a skillet Mexican fajitas recipe on this site that replicates grilled peppers and onions from Chipotle restaurant. Since the Instant Pot needs liquid for it to come to pressure, I’m using tomato sauce as a liquid to cook peppers and onions in this version of fajitas adapted to the Instant Pot. Sliced bell peppers and onions are cooked in tomato sauce and seasoned with chili powder and garlic powder – super flavorful!
Making these Instant Pot fajitas is super easy and quick! In fact, you will set your pressure cooking time on the Instant Pot to ZERO, yes 0 minutes :) The way this technique works is that vegetables cook during the time the Instant Pot is coming to pressure (which takes about 5 minutes). Once it comes to pressure, there is no need to cook them more, otherwise they’ll turn mushy. I used the same technique on many other quick-cooking vegetables – see my recipes for Instant Pot broccoli, Instant Pot cauliflower, Instant Pot green beans and Instant Pot asparagus!
Instant Pot truly makes everything easy. Just dump sliced bell peppers, sliced onions, tomato sauce, chili powder and garlic powder in the Instant Pot, press the button and in less than 5 minutes have perfectly cooked Mexican fajitas! And if you’d like to make an Italian version of peppers and onions instead of Mexican, skip the chili powder and add 1 tsp of Italian seasoning instead :)
These peppers and onions fajitas are very versatile. You can serve them as a vegetable side dish, over rice (Instant Pot cilantro-lime rice is an awesome option), in tacos or taco salad, burritos, salads, or as part of meal prep (see my Mexican mason jar salad recipe that uses fajitas as one of the layers)!
You can mix these peppers and onions with chopped rotisserie chicken to make chicken fajitas, or use them as building blocks for recipes such as chicken fajitas quinoa bowl or Mexican pasta fajitas. So yummy!
