Tools & Equipment Needed

This recipe is intentionally simple and requires minimal equipment:

• Large mixing bowl
• Measuring spoons
• Cutting board
• Sharp knife
• Large rimmed baking sheet
• Nonstick cooking spray
• Tongs or spatula
• Aluminum foil (for warming tortillas)

Step-by-Step Instructions

Follow these steps carefully to achieve perfectly cooked chicken and vegetables with classic fajita flavor.

Step 1: Preheat the Oven

Preheat your oven to 425 degrees Fahrenheit. This high temperature helps the vegetables roast quickly and encourages browning rather than steaming.

Step 2: Combine Ingredients

In a large bowl, combine the sliced red onion, yellow bell pepper, red bell pepper, orange bell pepper, and chicken breast tenders. Drizzle with extra virgin olive oil and add kosher salt, freshly ground pepper, chili powder, garlic powder, onion powder, ground cumin, and smoked paprika.

Toss everything thoroughly to ensure the chicken and vegetables are evenly coated with oil and spices.

Step 3: Prepare the Baking Sheet

Spray a large baking sheet with nonstick cooking spray. Spread the chicken, bell peppers, and onion evenly across the sheet pan in a single layer to promote even cooking.

Step 4: Roast

Place the baking sheet in the preheated oven and cook at 425 degrees for about 20 minutes, or until the chicken reaches an internal temperature of 165 degrees Fahrenheit.

Step 5: Broil for Color

Once the chicken is fully cooked, turn the oven to broil and cook for an additional 1–2 minutes. This step allows the vegetables to pick up a bit of color. Watch carefully to prevent burning.

Step 6: Warm the Tortillas

During the last five minutes of cooking, and not while the broiler is on, wrap the tortillas in foil and place them in the oven to warm.

Step 7: Finish and Serve

Remove the sheet pan from the oven. While the fajita mixture is hot, squeeze fresh lime juice over the chicken and vegetables. Top with fresh cilantro and serve immediately in warm tortillas.
