    Ingredients in sheet pan chicken fajitas

    Ingredients laid out to make keto chicken fajitas - chicken, peppers, onions, seasoning, garlic, limes, cilantro

    Ingredient Notes

    • Chicken: For this sheet pan chicken fajita recipe, I took a less traditional route and used skin-on, bone-in chicken thighs. The chicken is crispy on the outside and perfectly tender and juicy on the inside. But you could also use boneless chicken thighs, chicken breast cut into strips, or even shredded rotisserie chicken. Just adjust the cooking time accordingly. (more keto chicken recipes)
    • Seasoning: For this recipe you can use taco seasoning, fajita seasoning, or any Mexican blend of spices you may have on hand - chili powder, cumin, oregano, garlic powder, onion powder, paprika, salt, pepper, cayenne etc. 
    • Bell Peppers: I like to use a medley of red, yellow, orange and green bell peppers, but you can certainly use all of one color, or whatever you have on hand.
    • Onions: For this recipe I used sweet white onions, but this is also delicious with red onions, or even with some of my Pickled Red Onions.

    How to make Sheet Pan Chicken Fajitas

    Step by Step Instructions

    STEP 1: Put the bell peppers, onion, garlic, 2 tablespoons of the oil, the lime juice, and 2 tablespoons of the seasoning in a large mixing bowl. Toss the vegetables until they are evenly coated. Lay the vegetables in a thin layer across a rimmed baking sheet.

    STEP 2: Preheat the oven to 400°F. Season the chicken thighs on both sides with the remaining seasoning.

    STEP 3: Heat the remaining tablespoon of oil in a large cast-iron skillet over medium-high heat. Add the chicken to the pan and sear on both sides until the skin is crispy and golden brown. (The chicken will not be fully cooked at this point.)

    STEP 4: Transfer the chicken thighs to the sheet pan with the vegetables. Bake for 15 minutes, or until the chicken is cooked all the way through and the vegetables are tender. If desired, serve with lime wedges and garnish with cilantro or sliced green onions.

    Recipe Tips and Variations

    • Storage: Store leftovers in the refrigerator for up to 4 days.
    • Reheating: For the best flavor, I recommend reheating in a skillet on the stove-top, or in an air fryer so that you can get the chicken nice and crispy again. Alternatively, you can put the chicken under the broiler for a few minutes until heated through and crispy.
    • Serving suggestions: I like to serve these keto chicken fajitas with warm tortillas, sour cream, cheese, Roasted Tomatillo Avocado Salsa Verde, and guacamole. Here are some keto-friendly flour tortillas and almond flour tortillas.
    • Swap out the protein: These are also delicious made with steak or shrimp.
    • Add more veggies: In addition to the peppers and onions, I also like to add mushrooms, shredded Brussels sprouts or even cabbage.
    • Spice it up: For an extra kick, try adding some of my Pickled Jalapeños.
    • Sauce it up: Serve these sheet pan chicken fajitas with a drizzle of my Homemade Taco Sauce. Alternatively, you could marinate the chicken thighs in the sauce instead of coating them in seasoning.
    • Add fruit: If you are not concerned with keeping this low carb, it is delicious served with some fresh Pineapple Salsa.

    Frequently Asked Questions

    Can this be made in the air fryer?

    Yes, you can make these sheet pan chicken fajitas in an air-fryer, but you may need to do them in batches. Cook the vegetables for 5 to 7 minutes at 375°F. Then cook the chicken thighs for 20 minutes, or until cooked all the way through.

    What should I serve with these sheet pan chicken fajitas?

    I like to serve them with low carb tortillas, sour cream, cheese, guacamole, pickled jalapeños, and salsa
