Begin by gathering all of your ingredients:

Creamy Instant Pot Vegetarian Fajita Pasta ingredients

To make the instant pot vegetarian fajita pasta you will need:

Linguine– I like to use linguine for this pasta so the larger veggies don’t make it feel like a primavera as a thinner noodle like spaghetti might. You can really substitute any noodle you like just not that it may effect your pressure cooking time. Stick to the general rule of: half the lower end of the time stated on the pasta package + 2 minutes and you should be just fine. Elbows away!! (sorry, I’m not funny).

Cajun seasoning, I used this one, any Cajun or fajita seasoning you happen to like will work just fine here.

Garlic powder– as you will find in many of my recipes, this one being no exception, I generally prefer to use garlic powder over fresh garlic as I prefer the milder flavor and the ease of spreading the seasoning throughout the dish, while I feel minced garlic can become a bit clumpy in some dishes.

Olive Oil

Bell Peppers You will need two. I used yellow & red, but any combination would work (orange, purple, green, etc)

Fresh mushrooms– I used baby Bella, button or chopped Portobello would also work well if you need to substitute.

Red onion-yellow would work fine if you prefer.

Tomatoes– You will need two fairly decent sized tomatoes for this Instant Pot Fajita Pasta. You can sub in 4 roma-style tomatoes if your store is being dodgey on the full sized.

Vegetable broth

Skim milk-This is what I used, you can substitute 2% or whatever you prefer.

Flour– regular, all-purpose flour

Laughing Cow wedges– I use these a lot. I like that they are lighter than cream cheese and also give a pop of flavor to dishes.

Fresh Cracked Pepper

Scallions

Salt

Heat the olive oil in the Instant Pot on sauté mode. Add the onion, bell peppers and garlic powder and cook, stirring occasionally for several minutes.

When the cooking is done, allow a natural pressure release of 5 minutes, then quick release any remaining pressure.
Allow to sit until the sauce reaches the desired thickness.

What to serve with Pressure Cooker Vegetarian Fajita Pasta

This dish would work fine on its own as a light meal. If you are wanting some ideas for sides, here are a few:

Our Easy 4-ingredient Guacamole with some tortilla chips would be great.
Corn: on the cob, off the cob, with butter, corn fiesta salad, or our amazing crack corn dip would all be great pairings for this pasta.
A large salad full of greens, tomatoes, corn, beans, bell peppers, avocados, jalapenos and more would be perfect.
Guacamole Salad: guacamole, tomatoes, corn tortilla strips and some shredded lettuce like in a Mexican restaurant.
Marinated Tomatoes: season them with taco flavorings, fajitas seasonings or just some simple salt and pepper.
Fried okra: this classic crunchy side would be a great paring for this pasta salad.
Cornbread: Cajun flavors and cornbread go hand in hand, so why not serve some cornbread along with your fajita pasta.
Corn Salad
Succotash
Fresh pinto beans
Refried Beans
Coleslaw
Grilled shrimp or chicken
Hush Puppies: A bit less traditional with a pasta dish, but certainly works with the Cajun flavorings. These delicious fried bites are perfect if you are pairing the pasta with a protein.
