How to Make Instant Pot Chicken Fajitas
Step 1: Prep the Ingredients

Having everything prepped before you start makes this recipe come together really quickly.
Step 2: Add Everything to the Instant Pot
Layer the ingredients into the Instant Pot in the order listed in the recipe card: onions, bell peppers, chicken, olive oil, lime zest and juice, water or chicken broth, and fajita seasoning.
No need to overthink it! Just layer everything in and let the Instant Pot do the work.
Step 3: Pressure Cook
Secure the lid and make sure the pressure release valve is set to sealing.
Cook according to the recipe card, then carefully quick release the pressure once the cooking time is up.
Step 4: Toss and Serve
Once the lid unlocks, give everything a quick toss so the chicken, peppers and onions are coated in all those delicious fajita flavors.
Serve warm with your favorite toppings and enjoy!
Recipe Variations
These chicken fajitas are really easy to customize depending on what you have on hand.
Use different peppers. You can use any combination of bell peppers you like. The red, yellow and green peppers add lots of color, but feel free to use your favorites.
Add some heat. If you like spicy fajitas, add extra chili powder or serve them with your favorite hot sauce.
Make them creamy. A spoonful of sour cream or plain Greek yogurt makes a delicious topping and helps balance the spice.
Add your favorite toppings. Try shredded cheese, guacamole, salsa, fresh cilantro or extra lime juice.
Turn them into fajita bowls. Serve the chicken and vegetables over rice for an easy and filling dinner.
Expert Tips
Slice the chicken evenly. Cutting the chicken into slightly thinner slices helps it cook evenly.
Don’t skip the lime. The lime zest and juice add a bright, fresh flavor that really brings the fajita seasoning together.
Use chicken broth for more flavor. Water works perfectly fine, but chicken broth adds a little extra savory flavor.
Want firmer vegetables? Follow the note in the recipe card and sauté the vegetables first, then remove them before cooking the chicken.
Trust the recipe when it comes to the liquid. It may seem like 2 tablespoons of water or broth isn’t much, but the vegetables release moisture as they cook. The lime juice and olive oil also help create enough liquid for pressure cooking.
Mistakes to Avoid
Don’t cut the chicken too thick. Thinner slices help the chicken cook evenly and stay tender.
Don’t add extra liquid. The recipe is designed to work with the small amount of water or broth listed in the recipe card.
Don’t overcook the vegetables. If you prefer your peppers and onions to have a little more bite, use the sauté method mentioned in the recipe notes.
Don’t forget the seasoning. The homemade fajita seasoning is what gives this dish its signature flavor, so make sure it gets added evenly.
How to Store Leftovers
Have leftovers? Let the chicken and vegetables cool, then transfer them to an airtight container.
Store in the refrigerator and enjoy within 3 to 4 days.
When you’re ready to eat, simply reheat until warmed through. The vegetables may be a little softer after being refrigerated, but the fajitas will still be delicious.
How to Serve Chicken Fajitas
These fajitas are delicious served warm with tortillas and all your favorite toppings.
I like to set out sour cream, shredded cheese, guacamole, salsa, fresh cilantro and lime wedges so everyone can build their own fajitas.
You can also serve the chicken and vegetables over rice for an easy fajita bowl.
However you serve them, add a little fresh lime juice right before eating. That bright pop of citrus is the perfect finishing touch!

- ½ tbsp cumin
- 1 tsp garlic powder
- ½ tsp paprika
- ½ tsp dried oregano
- ½ tsp salt
- ½ tsp pepper
Instructions
- Prep the Ingredients: Slice the bell peppers and onion into 1/2-inch slices. Cut the chicken into slightly thinner slices to ensure even cooking.
- Add Ingredients to the Instant Pot: Layer the ingredients into the Instant Pot in this order: onions, bell peppers, chicken, olive oil, lime zest and juice, water (or chicken broth), and fajita seasoning.
- Cook: Secure the Instant Pot lid and set the pressure release valve to the sealing position. Press the [Pressure Cook] button and set the timer for 4 minutes on high pressure.

Notes
- Tip for Veggies: If you're concerned about overcooking the vegetables, you can sauté them first, then remove them and cook the chicken separately. Afterward, combine them.
- Liquid Amount: Though only 2 tablespoons of water or broth is added, don’t worry! The veggies will release their own moisture, and the lime juice and olive oil will help create enough liquid for cooking.
Nutrition
- Can I use frozen chicken breasts?
Yes, you can use frozen chicken breasts! Just add a few extra minutes to the cooking time (around 25 minutes on high pressure). Make sure the chicken reaches 165°F (74°C) for safety, and you’re good to go! - How do I keep the vegetables crisp?
If you’re worried about the veggies getting too soft, cut them into slightly thicker slices. Or, if you want extra control, sauté the peppers and onions first, remove them, then pressure cook the chicken separately. - Can I skip the chicken broth and just use water?
Definitely! Water works just fine. But if you’ve got some chicken broth hanging around, it’ll give the dish a little extra flavor. It’s up to you! - Can I double the recipe?
You can easily double the recipe! Just make sure not to fill your Instant Pot above the max fill line. The cooking time stays the same, but it might take a bit longer to come to pressure. - How can I adjust the spice level?
You can easily adjust the heat level! For less spice, simply cut back on the chili powder or skip the chipotle. Or, add a dollop of sour cream when serving to tone it down. It’s all about customizing to your taste!
