Ingredients
- 1 1/2 lbs boneless, skinless chicken breasts, sliced
- 3 bell peppers (any colors), sliced
- 1 large onion, sliced
- 2 tbsp olive oil
- 1 tbsp chili powder
- 1 tsp cumin
- 1 tsp paprika
- 1/2 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- Juice of 1 lime
For serving:
- Warm flour or corn tortillas
- Optional toppings: sour cream, guacamole, salsa, cilantro, shredded cheese
Easy swap: Use chicken thighs for extra juiciness.
Steps
- Preheat the oven. Heat to 425°F and line a large sheet pan with parchment or foil.
- Season everything. Add chicken, peppers, and onion to the pan. Drizzle with olive oil and sprinkle with all the spices, salt, and pepper.
- Toss gently. Use your hands or tongs to coat everything evenly. Don’t worry if it looks crowded it roasts beautifully.
- Roast. Bake for 18–22 minutes, stirring once halfway, until the chicken is cooked through and veggies are tender with lightly charred edges.
- Finish with lime. Squeeze fresh lime juice over the hot fajitas for brightness.
- Serve warm. Scoop into tortillas and add your favorite toppings.
Chef’s Tips
- Slice evenly: Similar-sized strips cook at the same pace.
- High heat matters: It gives you those lightly charred, fajita-style edges.
- Extra sizzle: Broil for 2 minutes at the end if you want more color.
Variations
- Spicy fajitas: Add a pinch of cayenne or sliced jalapeños.
- Steak or shrimp: Swap chicken for flank steak or shrimp (shrimp cook in about 10–12 minutes).
- Low-carb bowl: Serve over cauliflower rice or greens instead of tortillas.
