Sheet-Pan Chicken Fajitas
Sheet-Pan Chicken Fajitas
Yield: 4 servings
Equipment: large rimmed sheet pan, bowl, thermometer
Time and setting: 425°F; 18–24 minutes
Ingredients
- 1 1/2 pounds chicken breast, 1/2-inch strips
- 3 bell peppers, sliced
- 1 large onion, sliced
- 2 tablespoons olive oil
- 2 teaspoons chili powder
- 1 teaspoon cumin
- 1 teaspoon garlic powder
- 1/2 teaspoon salt
- 1 lime
- 8 six-inch tortillas
Method
- Heat oven to 425°F. Toss chicken, peppers, onion, oil, spices, and salt on pan.
- Spread in one layer. Roast 10 minutes, stir, then roast 8–14 minutes until chicken reaches 165°F.
- Squeeze half the lime over pan and rest 3 minutes.
- Warm tortillas and divide fajita mixture among eight; serve remaining lime alongside.
Substitutions
Turkey breast strips may replace chicken and require 165°F. Portobello strips may replace chicken for a meatless pan.
Storage and safety
Refrigerate within 2 hours up to 4 days. Reheat filling to 165°F. Freeze filling up to 2 months.
Cutting and pan arrangement
Slice chicken across the grain into strips close to 1/2 inch thick. Cut peppers and onion to similar width so they soften during the chicken’s cooking time. Pat chicken dry before adding oil and spices; surface moisture steams the pan and limits browning. Use a genuinely large rimmed sheet pan and spread everything in one layer.
Roasting and safety
After 10 minutes, turn chicken pieces and move vegetables from the cooler center toward the hotter edges. Check several thick strips with an instant-read thermometer inserted from the side; each must reach 165°F. Peppers should be tender with browned edges and onions translucent. If chicken finishes first, transfer it with clean tongs and roast vegetables briefly longer.
Serving variations
Warm tortillas in foil during the final five minutes, keeping the packet away from raw juices. Optional batch accompaniments include 1/2 cup salsa, 1/2 cup plain yogurt, or one diced avocado. For fajita bowls, omit tortillas and serve over 2 cups cooked rice divided among four portions.
Additional recipe guidance
The vegetables will release some moisture, so avoid lining the pan with a deep silicone mat that traps liquid; bare metal or parchment promotes better browning. Toss the spices with oil before spreading to coat chicken evenly. Wash the mixing bowl or use a clean one for any cooked ingredients. If doubling, use two sheet pans on separate racks and rotate them halfway rather than crowding one pan. The resting period allows juices to settle, but do not leave cooked chicken on the hot sheet indefinitely because carryover heat can dry thin strips. For meal preparation, divide the cooked filling into four containers and pack tortillas separately. Reheat the filling until 165°F, then assemble. Lime should be added after roasting because long high heat dulls its fresh aroma.
