Instant Pot Chicken Fajitas for Low-Carb and Keto Diets

We love this Instant Pot chicken fajitas recipe for its light, fresh flavors and simplicity. The chicken, bell peppers, and onions take center stage—seasoned just enough to let their natural taste shine.

Cooking with an Instant Pot can feel intimidating at first, and results sometimes vary, but they’re consistently tasty. If you’re new to pressure cooking, try a simple shredded chicken recipe first—once you’re comfortable, fajitas are an easy next step.

One important Instant Pot tip: never forget the water or other liquid. I’ve learned the hard way that the pot needs liquid to reach pressure. After cooking, if there’s a lot of liquid left, remove most of it and keep about a cup for texture and flavor.

Once the chicken is cooked and shredded, place the sliced peppers and onions on top. You’ll see the chicken peeking through beneath the vegetables. Add a can of tomatoes (or salsa) and taco seasoning, then mix gently to combine the flavors.

Next time I’ll toss in a red bell pepper too—these photos lean very yellow because the orange and yellow peppers lost some color while cooking. Still, that bright hue feels like sunshine on your plate.

I’m following a low-carb plan, so I serve these fajitas over cauliflower rice. A sprinkle of cheese and a dollop of Greek yogurt make it extra satisfying. Of course, they’re equally delicious stuffed into flour or corn tortillas if you prefer.

Every bite tastes a little like a homemade Chipotle bowl—bold, comforting, and perfect as leftovers. Leftover fajitas are great for breakfast, lunch, or an easy dinner the next day.

If you want a low-carb wrap option, many store-bought low-carb tortillas work well, or you can try homemade almond-flour or coconut-flour wraps. Experiment with tortilla bowls or other low-carb vessels to find your favorite way to serve these fajitas.

I also use Pinterest and food blogs to discover other low-carb Instant Pot recipes—ideas like cabbage and sausage are great for variety. But these chicken fajitas are always a go-to when I want a quick, flavorful meal.
