Ingredients You’ll Need for Sheet Pan Chicken Fajitas
- 1 1/2 pounds boneless skinless chicken breasts or thighs, sliced into strips
- 3 bell peppers (mixed colors), sliced
- 1 large red onion, sliced
- 3 tablespoons olive oil
- For the seasoning: 2 teaspoons chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon salt, 1/2 teaspoon oregano, 1/4 teaspoon cayenne
- Juice of 2 limes
- 8 to 10 flour or corn tortillas, warmed

How to Make Sheet Pan Chicken Fajitas
- Preheat the oven to 425°F and line a large rimmed baking sheet with parchment paper.
- Mix the chili powder, cumin, smoked paprika, garlic powder, salt, oregano, and cayenne in a small bowl.
- Toss the chicken, peppers, and onion with the olive oil and the seasoning mix until evenly coated.
- Spread everything in a single layer on the baking sheet, using two pans if needed to avoid crowding.
- Roast for 18 to 22 minutes, tossing once halfway, until the chicken reaches 165°F and the vegetables are tender and charred at the edges.
- Squeeze the lime juice over the pan and toss.
- Serve the fajita mixture in warm tortillas with guacamole, sour cream, salsa, cheese, and cilantro.
Tips for the Best Sheet Pan Fajitas
- Slice the chicken and vegetables to a similar thickness so they finish cooking at the same time.
- Don’t crowd the pan. Overcrowding steams the food instead of charring it, so use two pans when needed.
- Broil for 2 minutes at the end for a smoky, restaurant-style char.
- Use chicken thighs for extra juicy fajitas, or breasts for a leaner option.
Variations to Try
- Swap chicken for steak strips or shrimp
- Serve over rice as fajita bowls
- Add sliced jalapeños for heat
- Use sliced mushrooms and zucchini for extra vegetables
- Top with pickled red onions for tang
