Ingredients:
For the Fajitas:*
1½ pounds boneless, skinless chicken breasts, sliced into thin strips
3 medium bell peppers (mix of red and green), sliced into thin strips
1 large yellow or white onion, sliced into thin strips
3 tablespoons store-bought fajita or taco seasoning blend
Optional for Serving:*
Warm flour or corn tortillas
Shredded cheese
Salsa
Sour cream
Lime wedges
Instructions:
Step 1: Preheat Oven and Prepare Pan*
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with aluminum foil and lightly spray with cooking spray to prevent sticking.
Step 2: Arrange Ingredients on the Sheet Pan*
Place the sliced chicken, bell peppers, and onion on the prepared sheet pan. Spread them out in an even layer, ensuring the chicken strips are reasonably thin and similar in size.
Step 3: Season and Toss*
Sprinkle the fajita seasoning over the chicken and vegetables. Toss everything together with clean hands or tongs until evenly coated. Spread the mixture back into a single, even layer.
Step 4: Roast*
Bake for 18-22 minutes, stirring once halfway through, until the chicken is cooked through and the peppers and onions are tender with lightly charred edges.
Step 5: Broil (Optional)*
For more browning, switch the oven to broil for 2-3 minutes at the end, watching closely to prevent burning.
Step 6: Serve*
Taste and add a little extra seasoning if desired. Serve hot in warm tortillas with your favorite toppings.
