Variations & Substitutions

How to Make Instant Pot Chicken Fajitas
Slice bell peppers and onions into roughly ½-inch strips. Slice the chicken slightly thinner so everything cooks evenly.
Layer the ingredients in the Instant Pot: start with the onions and peppers, then top with the chicken. Drizzle with olive oil, add lime zest and juice, pour in a small amount of water or broth, and sprinkle the fajita seasoning evenly over the top.
Seal the lid and pressure cook on high for 4 minutes. Perform a quick release when the cook time ends to keep the chicken tender and prevent the vegetables from becoming overly soft.
Toss everything together and serve immediately with your favorite toppings.

Tips for the Best Instant Pot Chicken Fajitas
✔️ Slice the veggies a bit thicker so they hold up in the Instant Pot.
✔️ Layer vegetables on the bottom and chicken on top to reduce the chance of a burn notice.
✔️ Quick release the pressure to avoid overcooking the chicken and softening the vegetables too much.
✔️ For firmer peppers, sauté them first, set aside, and fold them back in after pressure cooking.
✔️ Finish with a squeeze of lime for a bright finish.
Favorite Fajita Toppings
Let everyone build their own plate. Common toppings that pair well include sliced avocado or guacamole, sour cream or Greek yogurt, shredded cheese, fresh cilantro, salsa or pico de gallo, and sliced jalapeños for heat. Warm flour or corn tortillas and extra lime wedges are always welcome.
These fajitas also work well over rice or tossed into a salad for a lighter meal.
FAQs
It’s best not to. Frozen chicken will take longer to come to pressure and cook, which will overcook the vegetables. Thaw the chicken first for the best texture and seasoning adherence.
Slice them thicker and position them under the chicken or sauté and add them back in after pressure cooking. Quick releasing the pressure also helps keep them crisp-tender.
Don’t discard it. Use a slotted spoon to keep tortillas from getting soggy, spoon the juices over rice bowls, reduce them with the sauté function for a sauce, or save as a flavorful broth for future use.
Yes. Just avoid filling the Instant Pot beyond the max fill line; the cooking time remains the same.
