Ingredients

3 bell peppers, seeds removed, sliced ¼-inch thick

1 yellow onion, thinly sliced

1 tablespoon vegetable oil (for vegetables)

1 to 1 ½ lb chicken breasts, sliced ¼-inch thick

2 tablespoons vegetable oil (for chicken)

2 tsp chili powder

1 tsp cumin

1 tsp garlic powder

1 tsp kosher sea salt

½ tsp ground black pepper

½ tsp paprika

½ tsp coriander

⅛ tsp chili flakes or cayenne pepper (optional)

1 fresh lime

Instructions

Step 1: Preheat your oven to 400°F (200°C). Place a rimmed baking sheet inside to heat up while you prepare the ingredients—this ensures a nice hot surface for roasting.

Step 2: In a large bowl, combine 1 tablespoon of vegetable oil with the sliced bell peppers and onions. Toss well to coat the vegetables evenly.

Step 3: Carefully remove the hot baking sheet from the oven, spread the peppers and onions evenly across it, and return it to the oven. Bake for 8 minutes to begin roasting.

Step 4: While the vegetables roast, mix the remaining 2 tablespoons of vegetable oil with the sliced chicken breasts and all the spices: chili powder, cumin, garlic powder, kosher salt, black pepper, paprika, coriander, and chili flakes if using. Toss thoroughly to coat evenly.

Step 5: Remove the baking sheet from the oven again once the vegetables have pre-roasted. Drain any excess liquid, then evenly arrange the seasoned chicken slices on the sheet, avoiding overlap for even cooking.

Step 6: Return the sheet to the oven and bake for 15 to 20 minutes more, or until the chicken is cooked through and both the chicken and vegetables are golden brown and roasted to perfection.

Step 7: Remove from the oven and immediately squeeze fresh lime juice over the fajitas for a bright, tangy finish. Serve warm with toppings like sour cream, guacamole, or salsa.

Tips & Variations

Use a mix of bell pepper colors for a vibrant presentation and varied flavor.

For extra smoky flavor, add a pinch of smoked paprika or chipotle powder to the spice mix.

Swap chicken breasts for thighs if you prefer juicier meat.

Serve with warm tortillas and fresh cilantro for classic fajita style.

If you like it spicier, increase the chili flakes or add a sliced jalapeño to the vegetable mix.
