🛒 Ingredients for Baked Chicken Fajitas

Main Ingredients:

• 1.5 lbs boneless, skinless chicken breasts, sliced into thin strips
• 3 bell peppers (red, yellow, and green), thinly sliced
• 1 large red onion, sliced
• 2 tbsp olive oil
• Juice of 1 lime

Fajita Seasoning:

• 2 tsp chili powder
• 1 tsp ground cumin

• ½ tsp garlic powder
• ½ tsp onion powder
• ½ tsp sea salt
• ¼ tsp black pepper
• ¼ tsp crushed red pepper flakes (optional)

🍽️ How to Make One-Pan Chicken Fajitas

Step 1: Start by preheating your oven to 400°F (200°C).

Step 2: In a large bowl, toss together the chicken strips, bell peppers, and onions. Drizzle with olive oil and lime juice, then sprinkle on the seasoning blend. Mix until everything is evenly coated.

Step 3: Arrange the mixture in a single layer on a large sheet pan or baking dish.

Step 4: Bake for 25–30 minutes, flipping halfway through, until the chicken is cooked through (internal temperature should reach 165°F) and the vegetables are slightly charred and tender.

Step 5: Serve hot with warm tortillas, rice, or on a bed of greens for a low-carb version.
