Above the tray, there's a white bowl full of mashed beans with some green herb garnish. To the left, a white bowl holds chunky green guacamole topped with small herb pieces, and beside it is a smaller clear bowl with finely chopped red, yellow, and white vegetables. A stack of round tortillas wrapped in foil sits on the tray towards the top left, and a white plate with sliced avocado pieces is visible in the background.

Ingredients

1 ½ pounds boneless skinless chicken breast, sliced into thick strips
3 bell peppers, sliced into strips
1 red onion, thinly sliced
2 garlic cloves, minced
3 tablespoons olive oil
2 teaspoons chili powder
1 teaspoon cumin
1 teaspoon paprika
½ teaspoon coriander
½ teaspoon onion powder
½ teaspoon salt
½ teaspoon black pepper
Flour tortillas
Lime wedges
Fresh cilantro
Avocado

Instructions

Step 1: Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper for easy cleanup.
Step 2: Arrange the sliced chicken, bell peppers, red onion, and minced garlic on the prepared baking sheet. Drizzle with olive oil.
Step 3: In a small bowl, mix chili powder, cumin, paprika, coriander, onion powder, salt, and black pepper. Sprinkle this seasoning evenly over the chicken and vegetables.
Step 4: Toss everything together using tongs or your hands to coat the ingredients well with the oil and spices. Spread the mixture out in an even layer.
Step 5: Roast in the oven for 15-20 minutes, tossing once halfway through, until the chicken is cooked through and the vegetables are tender. During the last 5 minutes, wrap a stack of tortillas tightly in foil and place them on the baking sheet to warm.
Step 6: Serve the chicken and vegetables hot with the warmed tortillas, along with lime wedges, fresh cilantro, and sliced avocado as garnish.

Tips & Variations

Use a mix of colorful bell peppers for a vibrant presentation and a variety of flavors.
For extra smoky flavor, add a pinch of smoked paprika.
Swap chicken breast for thighs if you prefer juicier meat.
Serve with sour cream or a drizzle of crema for added creaminess.

Storage

Store any leftover chicken fajitas in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave. Keep tortillas separate to prevent them from becoming soggy, and warm them fresh before serving.

FAQs

Can I use frozen chicken for this recipe?

It’s best to use fresh chicken or fully thawed frozen chicken to ensure even cooking. Frozen chicken may release excess moisture and cook unevenly.
