Your instant pot is not just for soups and stews. It can make a variety of different foods including your favorite weeknight dinners or Mexican takeout. These instant pot chicken fajitas are a great way to create a healthy meal that will bring the family together. 

🤔 Why Cook Chicken Fajitas In The Instant Pot?

  • It’s made with simple ingredients you can control unlike at a restaurant.
  • Pressure cooked chicken turns out tender and flavorful without any time spent marinating. 
  • You can add all the ingredients into the pot, set it and walk away so you don’t have to babysit the skillet giving you more time.
  • Everything cooks all in one pot which helps minimize clean up.
  • Cooks in under 20 minutes from start to finish.

🥘 What You’ll Need To Make Instant Pot Fajitas:

  • Chicken Breast: This will be cut into even sized strips about ½ inch wide. See notes about using frozen chicken. You could also use chicken thighs if you prefer it.
  • Sliced Bell Peppers: Use any color you like. I enjoy using red and yellow bell peppers because they add a great sweetness to the dish.
  • Sliced Onion: A classic fajita vegetable.
  • Fresh Lime Juice: Nothing says fajitas like fresh lime. This gets tossed into the chicken and onion mix to pressure cook in the flavor.
  • Homemade Fajita Seasoning: See below for my homemade fajita seasoning mix. Alternatively, you could also use a packet of fajita mix or a taco seasoning in a pinch.
  • Chicken Stock Or Water: This helps the pressure cooker make sure there is enough liquid to cook the fajitas and not get the burn notice. 
  • Recommended EquipmentPressure Cooker: I love using my Ninja Foodi to make fajitas as it is a pressure cooker and air fryer all in one.

Homemade Fajita Seasoning

This is my recipe for homemade fajita seasoning from scratch. If you’d rather use a seasoning packet, you could do that too! Just make sure you also add the fresh lime juice.

  • 2 tsp Chili Powder
  • 1 tsp Paprika
  • ½ tsp Cumin
  • ½ tsp Onion Powder
  • 1 tsp Garlic Powder
  • 1 tsp Salt
  • ¼ tsp Ground Black Pepper

📖 How to Make Instant Pot Chicken Fajitas

1️⃣ Prepare Your Ingredients: Slice up your chicken breast into half inch strips trying to make them all the same size so they cook evenly. Slice your bell peppers and onion into half inch strips as well.

2️⃣ Add To Instant Pot: Add the sliced chicken, peppers and onions to your instant pot. Then add in your fajita seasoning and fresh lime juice.

3️⃣ Toss Everything Together: Using tongs, fully coat the chicken, peppers and onions with the seasoning and lime juice until it’s fully combined. Then add chicken stock or water to the bottom of the pot.

4️⃣ Pressure Cook: Set your pressure cooker for 5 minutes on manual high pressure.

5️⃣ Quick Release: Once your fajitas are done cooking, do a quick release then turn off the heat to ensure that the peppers do not get overcooked.

6️⃣ Serve: Serve hot with tortillas or over a bowl of rice or riced cauliflower.

♨️ Pressure Cooking Frozen Chicken For Fajitas

One tip to save time is to directly cook your chicken from frozen. 

  • Frozen Chicken Strips: Add to the bottom of the pot, season and add stock. Add peppers and onions on top and increase the cooking time by 2 minutes. Because it’s frozen, the instant pot will adjust and take longer to come to pressure.
  • Full Frozen Chicken Breasts: You can cook these before hand using this Instant Pot Frozen Chicken Method. Add in the seasoning with the chicken, shred it once it’s cooked and add in the raw peppers and onions afterward letting the heat of the chicken gently cook the vegetables. 

🧑‍🍳 Recipe Tips

Try to cut up the chicken and peppers so they are the same size. This will ensure that everything cooks evenly. 

If you are worried about your peppers becoming mushy, add the chicken FIRST, toss in the seasonings and then add your peppers and onions on top. This will essentially steam them making them a bit more crisp than if they were mixed in completely.

Adding the chicken stock or water is important because it allows the water to create steam pressure. Only ¼ cup is needed as the chicken and veggies will naturally release water. 

A quick release is important on this dish as if it stays in longer, the peppers and onions have potential to become mushy.

    Amazing recipe, I have used it twice and both times it has come out fantastic!!! My personal tweaks are doubling the garlic, adding cayenne, and using two tbsps of lime juice instead of a lime. These tweaks are 100% unnecessary just personal preference. I use this meal for my work lunches with a little bit of salsa and crispy onions added on top so I can verify it reheats really well.
