This Instant Pot chicken fajitas recipe is the perfect quick and easy dinner for those busy weeknights that the whole family will love.

I'm a big fan of fajitas - from sweet potato fajitas to sheet pan chicken fajitas.
Yes the traditional way to make fajitas is in a cast iron skillet but you can always mix things up, like making them in the aforementioned Instant Pot!
When I think of Instant Pot meals, I think of something where you just throw everything together and let it do work. And within 30 minutes you have a delicious meal.
And these Instant Pot chicken fajitas are no different. Just throw everything in and set it and forget it. And while I like to make my own seasoning, you can easily just use a store-bought packet.

Ingredient Notes
- Boneless, skinless chicken breasts - the base for these fajitas.
- Veggies - to me you can't have fajitas without some peppers and onions.
- Spices - I like to make my own seasoning but if you don't want to make your own, just buy fajita seasoning.
- Chicken stock - you need some liquid so it doesn't burn in the Instant Pot.
Ingredient Swaps
Like any recipe, you can mix up some the ingredients if you'd like. Some variations include:
- I like chicken breasts for this recipe, but thighs work as well.
- If you don't have white onions, sweet, yellow, red onions or shallots will work too. They all high slightly different flavors.
- While cornstarch is best to thicken the liquid, you can use flour as well?
- Flour tortillas are my go-to for fajitas, but whole wheat are good substitutes.

Add all of the ingredients to the Instant Pot and mix everything up. Close the lid and turn vent to "sealing." Set to manual/high pressure for 7 minutes.
Once done, allow it to naturally release for 5 minutes before doing a quick release.
FAQs
The great thing about an Instant Pot is either works. If using frozen, just add 5 minutes to the cooking time.
While onions and bell peppers are the most traditional veggies included in fajitas, you can use any type of vegetable you like, from mushrooms to corn to zucchini.
When cooking in an Instant Pot, you need some liquid, or you'll get the burn notice before it reaches temperature. Once cooked, the peppers release their water as well.
If you have this issue, you can remove the chicken, peppers and onion and throw on a pan. Broil for just a couple of minutes.
I don't like to waste the extra liquid as it is loaded with flavor. You can use it to make some Instant Pot fajita rice.
Leftovers will store well in the fridge for 2-3 days in an air-tight container or be frozen for 3 months.
If you reheat the chicken in the microwave, they might become slightly rubbery. Just heat the chicken and veggies in a skillet with some oil over medium heat until everything is warmed through.
