Ingredients

• Chicken Breast: Provides lean protein and absorbs all the flavors from the seasoning. For the best texture, slice against the grain into thin strips.
• Bell Peppers: Add vibrant color, a mild sweetness, and crunch. Use a mix of red, yellow, and green for the most flavor and visual appeal. Pick firm, shiny peppers with no soft spots.
• Onion: Adds a subtle sweetness as it caramelizes during cooking. Choose medium-sized onions that are firm to the touch. Yellow onions work best for this dish.
• Garlic: Delivers a savory kick to the fajita seasoning and marinade. Fresh garlic cloves are best for flavor. 
• Lime Juice: Helps tenderize the chicken while adding a fresh burst of acidity. Use fresh lime for the best flavor.
• Olive Oil: Coats the chicken and vegetables, helping the seasoning stick and creating a rich texture when baked. 
• Cilantro: Adds a fresh, herbal note to balance the spices. Choose fresh cilantro with bright green leaves.
• Flour Tortillas: Soft tortillas that wrap the fajita filling. Warm them in the oven to soften.
• Fajita Seasoning: A homemade blend of chili powder, cumin, paprika, and other spices that gives the dish its signature bold taste. You can store any leftover seasoning for future recipes.

Variations

• BBQ Fajitas: Swap the fajita seasoning for a smoky BBQ rub and drizzle with your favorite BBQ sauce for a sweet and smoky flavor. 
• Veggie-Only Fajitas: For a vegetarian or vegan version, skip the chicken and use a mix of extra vegetables like zucchini, mushrooms, and cauliflower. These veggies roast beautifully and soak up the seasoning just as well.
• Swap the Protein: Instead of chicken breast, try using thinly sliced steak, shrimp, or tofu for a different protein option.
• Spicy Kick: Add some heat by including sliced jalapenos or a dash of cayenne pepper to the seasoning mix. You can also use a spicy salsa or hot sauce as a topping for extra heat.
• Sweet Twist: Add a touch of sweetness by tossing in sliced pineapple or mango with the peppers and onions. This will balance the heat and create a fun, tropical flavor.

How to Make Sheet Pan Chicken Fajitas

Making these sheet pan chicken fajitas is quick and simple! With just a few easy steps, you'll have a delicious meal in no time. Start by preheating your oven to 400° and prepping your baking sheet. 

1. Step 1: Mix the Fajita Seasoning. Stir together all the fajita seasoning ingredients in a small bowl.
2. Step 2: Assemble Everything in the Pan. Lay the sliced bell peppers and onions on the prepared sheet pan and place the sliced chicken on top. Sprinkle the fajita seasoning over everything, followed by the minced garlic and olive oil.
3. Step 3: Bake. Place the sheet pan in the oven and bake for 18-25 minutes, or until the chicken reaches an internal temperature of 165°. The veggies should be tender and slightly caramelized.
4. Step 4: Warm the Tortillas & Serve. Wrap the tortillas in foil and place them in the oven during the last 5 minutes of cooking time. Once the oven-baked fajitas are done, squeeze fresh lime juice over the top and garnish with cilantro before serving in the warm tortillas.

• Reheating: For best results, reheat the fajita filling in a skillet over medium heat with a splash of water or chicken broth to keep it moist. You can also use the microwave in 30-second intervals.
