Sheet pan meals are a lifesaver for busy families, and these Sheet Pan Chicken Fajitas deliver bold Mexican-inspired flavors with minimal effort.

These fajitas are versatile, family-friendly, and work well for meal prep: make a double batch to portion into containers for lunches or dinners during the week.

Ingredients You’ll Need

• Chicken – 1 1/2 lb boneless, skinless chicken breasts, cut into 1/2-inch strips (you can also use boneless, skinless chicken thighs).
• Bell peppers – 3 bell peppers, thinly sliced (use any color combination: red, yellow, green). Optional: add sliced poblano or jalapeño for heat.
• Onion – 1 medium onion, thinly sliced (yellow, white or red onion will work).
• Olive oil – 2 Tbsp olive oil to coat the chicken and vegetables.
• Seasonings – 2 tsp chili powder, 1 tsp cumin, 1 tsp paprika, 1/2 tsp garlic powder, 1/2 tsp oregano, plus salt and pepper to taste.
• Lime juice – Juice of 1 lime to finish and brighten the dish; fresh lime is recommended.
• Optional tortillas – Flour or corn tortillas for serving; can be omitted for bowls or lettuce wraps.
• Toppings – Chopped cilantro (about 3 Tbsp), avocado, salsa, shredded cheese, sour cream or your favorite garnishes.

How to Make Sheet Pan Chicken Fajitas

1. Preheat and prepare. Preheat your oven to 400°F (200°C). Cut the chicken into strips and thinly slice the bell peppers and onion. Arrange the chicken and vegetables in a single layer on a large rimmed baking sheet coated lightly with cooking spray or a thin layer of oil.
2. Season. Drizzle the 2 tablespoons of olive oil over the chicken and vegetables. In a small bowl, mix the chili powder, cumin, paprika, garlic powder and oregano. Sprinkle the spice blend evenly over the pan, add salt and pepper, and toss everything to coat.
3. Bake. Spread the mixture into an even layer and bake for 20–25 minutes, tossing once halfway through, until the chicken is cooked through and the vegetables are tender. For a bit of char on the peppers and onion, remove the chicken after cooking and broil the vegetables for 3–5 minutes until the edges brown slightly.
4. Finish and serve. Drizzle the cooked chicken and peppers with fresh lime juice and sprinkle with chopped cilantro. Serve immediately in warmed tortillas, over rice, or in lettuce cups with your favorite toppings.

Sheet Pans Recommended

For sheet pan dinners, choose a durable, rimmed baking sheet with enough surface area to spread ingredients in a single layer. A thicker pan helps distribute heat evenly and prevents warping. If you plan to cook large batches for meal prep, opt for a large or half-sheet pan to avoid overcrowding, which can steam the vegetables instead of roasting them.

Storage and Meal Prep Tips

This recipe is ideal for prepping ahead. Chop the vegetables and slice the chicken the night before, mix the dry seasoning in a small container, and refrigerate everything separately until you’re ready to assemble. When time is short, just spread the prepped ingredients on the sheet pan, toss with oil and spices, and bake.

Leftovers store well in airtight containers in the refrigerator for 3–4 days. Reheat in the oven or skillet for best texture, or enjoy cold in a salad. These fajitas reheat nicely over cooked brown rice, cauliflower rice or wrapped in tortillas for a quick weeknight meal.
