Ingredient Notes
This easy sheet pan chicken fajitas recipe uses simple grocery store ingredients and a quick homemade seasoning blend. The vegetables can be adjusted based on what you have on hand, but the combination below gives the fajitas great color, texture, and flavor.

- Chicken Breasts – Boneless skinless chicken breasts work well for this recipe. Slice them into ½-inch strips and cut against the grain so the pieces stay tender after baking. Packaged raw chicken tenders can also be used if you want to save prep time.
- Bell Peppers, Onion & Zucchini – This mix adds sweetness, color, and a fresh vegetable balance to the seasoned chicken. You can use any color bell peppers and swap the vegetables for your favorites if needed.
- Jalapeno – Jalapeno adds a little heat and fresh pepper flavor. If you prefer mild chicken fajitas, leave it out or reduce the amount.
- Homemade Fajita Seasoning – Lime juice, oil, chili powder, cumin, garlic powder, onion powder, salt, black pepper, and optional red pepper flakes create a simple marinade that seasons both the chicken and vegetables.

How to Make Sheet Pan Chicken Fajitas
These sheet pan fajitas are very simple to prepare. Most of the hands-on time is spent slicing the chicken and vegetables. A 30-minute marinade gives the chicken and vegetables more flavor, but if you are short on time, you can bake the fajitas right away.

STEP 1: Make the fajita seasoning marinade. In a small bowl, stir together the lime juice, oil, chili powder, cumin, garlic powder, onion powder, kosher salt, black pepper, and red pepper flakes until combined.

STEP 2: Add the sliced chicken, bell peppers, onion, zucchini, and jalapeno to a large mixing bowl. Pour the marinade over the chicken and vegetables, then toss well so everything is evenly coated.

STEP 3: Cover the bowl with plastic wrap and marinate in the refrigerator for 30 minutes, or up to 2 hours. Do not marinate longer than 2 hours, because the lime juice can begin to change the texture of the chicken.

STEP 4: Spread the chicken fajita mixture onto a large sheet pan in an even layer. Bake until the chicken reaches an internal temperature of 165°F and the vegetables are tender. Finish with fresh cilantro and serve with tortillas and toppings.
Expert Tip
If you prefer very soft vegetables, slice them thinly so they cook through in the same amount of time it takes for the chicken to reach 165°F on an instant-read thermometer.
