Now you can whip up juicy, tender, flavor-packed chicken fajitas without the steaming, sizzling pan… This instant pot chicken fajitas recipe lets you cook your meat AND veggies in the pressure cooker, at the same time—in under 15 minutes! All you’ll need are tortillas and toppings, and you’ve got an easy weeknight dinner ready to serve.

Don’t worry, these instant pot chicken fajitas are just as tasty as the classic recipe. You’ll just spend way less time and effort in the kitchen making them! The chicken breast turns out so satisfyingly juicy, with that savory, zesty, fajita-flavor kick we all know and love.

Seriously, despite the very short cooking time of most instant pot recipes, it surprises me how much flavor pressure cooking can pack into a dish! These instant pot chicken fajitas turned out so melt-in-my-mouth good—with a deeply-infused flavor that was almost like they’d been slow-cooked. But, I didn’t have to wait around ALL day for it to cook!
Oh yeah, and did I mention this healthy chicken fajitas meal will FREEZE really well for later? Clean and wholesome, quick and easy, and totally freezable—safe to say this instant pot dinner is a meal-preppers dream.
Part of the beauty of instant pot meals is the instant convenience. Just have your chicken marinating ahead of time (rather than running your slow cooker or crock pot all day), and you can toss it into the instant pot half an hour before dinner time! Plus, I absolutely LOVE the added convenience of 2-in-1 pressure cooker recipes.
In this instant pot chicken fajitas recipe, you can cook your chicken AND your veggies together in the cooker, simultaneously! But, I’ll also show you how to keep your marinated fajita chicken separate from your seasoned fajita veggies. While they’re both in the cooker at once…
…Say whaaaa?! It is possible—with the help of an oh-so-handy instant pot steam rack!
I’ll show you how to make chicken fajitas in the instant pot using my nifty 2-in-1 hack, and you can apply this trick to TONS of other instant pot meals. Whether it’s these instant pot chicken fajitas, or butter chicken and rice, or even spaghetti and meatballs in the pressure cooker—your 2-in-1 possibilities are endless!
How to Make Chicken Fajitas in the Instant Pot
To start, you’ll need to marinate your chicken breast for a short while. A good marinade needs a bit of acid in it (like the lime juice in this recipe), because it loosens up the tightly-coiled proteins in the meat. That loosening makes room for some moisture and your flavorings to get trapped inside the meat—making these instant pot chicken fajitas even juicier and tastier!
You can marinate in a dish or bowl if you like, or I personally prefer to use a large zip-top bag for ease and convenience. (And less mess!) I just add all of my fajita marinade ingredients to the bag, seal it up, and shake to mix everything together.
Then, add sliced chicken to the marinade and seal up the bag again, with a little air left inside. Give it a good shake once more so you coat the chicken thoroughly with the fajita marinade. Finally, remove as much air as you can and reseal the bag—you want as much contact between the meat and marinade as possible—before storing in the fridge for 1-2 hours.
If needed, either for meal prep purposes or on busier days, you can also allow your fajita chicken to marinate overnight. But, I don’t recommend leaving it any longer than that! After about 2 days, meat left sitting in an acidic marinade can actually become tougher and drier as the proteins tighten up.
Now, for the veggies—which you can prep right before you’re ready to cook. Some people make instant pot chicken fajitas simply by tossing their sliced veggies right on top of the chicken in their cooker and letting ‘er rip. Which you’re totally welcome to do! OR, you can cook your chicken and veggies separately with the neat 2-in-1 steam rack hack I’m about to show.
So, for the fajita veggies made 2-in-1 style, you’ll need a large mixing bowl lined with a large piece of foil. You’re basically going to wrap up your seasoned vegetables in a foil pocket/pouch, so make sure you’ve got enough foil to wrap them up completely!
Add your sliced bell peppers and onions to the foil cavity, followed by your oil, seasonings, and lime juice. Give it all a good toss with your hands to coat well, then fold the edges of the foil together to seal up your foil veggie pocket.
With your bag of marinated chicken, pour both the chicken and the rest of your marinade into the instant pot. Use a spoon to arrange the chicken pieces in a flat/even layer, making room for the most magical of 2-in-1 tools: an instant pot steam rack.
A steam rack lets you pressure cook 2 separate items in the instant pot at once, and it’s such a solid (and cheap!) investment. It makes instant pot meals of all kinds even more versatile, convenient, and customizable. I got a super affordable pack of 3 steam racks from Amazon, and they’ve changed my life…
When making chicken fajitas in the instant pot, simply place your steam rack into the bottom of the cooker so it’s hovering over the chicken. You want the rack to be touching the bottom of the pot, but tall enough so it’s not crushing your meat. Then, add your foil pocket right on top of the steam rack, and you’re ready to cook!
Close up the lid of your pressure cooker and cook on your machine’s manual setting at high pressure for just 7 minutes. Easy-peasy! Granted, it will take a few extra minutes to heat up before the pressure-cooking actually begins, but overall this recipe is SO quick and easy thanks to the magic of the instant pot.
Quick note: I have a Crock-Pot brand pressure cooker, not the official Instant Pot brand, so I access my manual setting with the ‘BEANS/CHILI’ button. This may be different for your cooker, depending on the brand/model, but just check your machine’s instructions or the brand’s website if you need help!
After the 7 minutes of cooking has finished, turn off the heat but don’t open up the lid just yet. First, flip your Quick Release valve and let the steam release for 6 minutes.
Even after the steam release finishes, be careful opening the lid because it will still be very hot and steamy! Grab some oven mitts or kitchen towels to protect your hands while you remove your foil veggie pocket, followed by the steam rack in the bottom of your cooker.
Underneath, you’ll find your juicy, HEALTHY fajita chicken ready to go and perfectly-cooked—in just about 15 minutes! Use tongs or a spoon to remove the chicken from the cooker, open up your foil pocket full of tender fajita veggies, and it’s all ready to serve straight out of the pot.
Serve it up buffet-style for the whole family with tortillas and your favorite fajita fix-in’s, so everyone can customize their own meal! It doesn’t have to be complicated—I’m a big fan of guacamole, sour cream, and a squeeze of lime juice, but use whatever you enjoy. Or, allow your chicken and veggies to cool before storing in separate containers in the fridge for the week.
BONUS: You can also FREEZE this instant pot chicken fajitas meal after cooking, so you’ve got a flavorful and fuel-filled meal on-hand in the freezer when needed! (You can check out the specific steps for freezing in the recipe below.)
Substitutions: Do I Have to Use Chicken Breast in this Instant Pot Chicken Fajitas Recipe?
Absolutely not! Chicken breast is a great option for this recipe if you’d like to use it—it slices up easily, it stays tender and juicy in the instant pot, and it makes for a protein-packed dinner. But, you can also use chicken thighs, or even sliced steak if you prefer!
Personally, I prefer chicken thighs over chicken breast, because the higher fat content makes the thigh meat for more flavorful and just plain ol’ scrumptious after cooking. Those fats are also highly nutritious for our bodies and make chicken thighs a more satiating protein option. And they’re packed with loads of essential micronutrients!
Steak can substitute just as well in this instant pot chicken fajitas recipe—just be sure to cut it into fajita-sized strips/slices before cooking. Again, I enjoy steak because it tends to be a bit higher in fat, making for a juicier, more flavorful meat in my fajitas.
Whatever you choose—chicken breast, thighs, or steak—the pressure-cooking time and temperature provided in the recipe be the same!Print
