Why you’ll love this recipe
- Hands-off. After slicing the chicken, peppers, and onions, the Instant Pot does the work, making this one of the easiest fajita recipes you’ll make.
- Fast. From prep to plate in under 30 minutes, including slicing the vegetables.
- Versatile. Serve the chicken and peppers in warmed tortillas for fajitas, spoon them over rice for a burrito bowl, use them in a taco salad, or fill enchiladas.
- Healthier. Made with lean chicken breast and no added oil, these fajitas are lower in fat but still full of flavor.
Notes on ingredients
- Chicken: Use boneless, skinless chicken breasts cut into ½-inch strips, or chicken tenders. This ensures accurate cooking time and tender results.
- Bell peppers: Use any color combination—red and yellow add sweetness while green adds a fresh note. A mix looks attractive on the plate.
- Onion: Choose a yellow, white, or sweet onion. Red onions don’t soften as well under pressure, so they’re not recommended here.
- Chicken stock: Low-sodium store-bought or homemade stock works. Use ½ cup for a 3- or 6-quart Instant Pot or ¾ cup for an 8-quart model; the vegetables and chicken release additional liquid during cooking.
- Fajita seasoning: Homemade or store-bought fajita or taco seasoning works. The recipe’s blend includes smoked paprika, garlic powder, onion powder, cumin, chili powder, and salt.
- Limes: Fresh lime zest and juice brighten the dish and elevate the flavors—don’t skip them.
How to make Instant Pot Chicken Fajitas
These tips help you get great results. Exact ingredient amounts and step-by-step instructions are in the recipe card below.
- Prepare the chicken. Trim any fat and slice chicken breasts lengthwise into ½-inch strips. Toss the chicken with half of the fajita seasoning so it’s evenly coated, then add it to the Instant Pot with the measured chicken stock.
- Add peppers and seasoning. Top the chicken with sliced onion, sliced peppers, and minced garlic. Sprinkle the remaining fajita seasoning evenly over the vegetables.
- Pressure cook. Lock the lid and set the valve to sealed. Cook on High Pressure for 4 minutes using the pressure cook/manual setting. When the time ends, allow a natural pressure release for 10 minutes—this keeps the chicken tender.
- Finish with lime. Remove the lid, then use a slotted spoon to transfer chicken, onions, and peppers to a bowl. Add the zest and juice of fresh limes and toss to coat. The citrus brightens the flavors and brings the dish together.
- Serve. Spoon the chicken and pepper mixture into warmed flour tortillas and top with sour cream, sliced avocado, shredded cheese, or your favorite taco toppings. You can also serve it over rice or in bowls with guacamole and salsa.
Serving suggestions
Pair these Instant Pot Chicken Fajitas with Instant Pot Spanish Rice, refried beans, or a fresh salad for a full Tex-Mex meal. They’re also great over jasmine rice with guacamole for a quick burrito bowl or as the filling for enchiladas and casseroles.
