How to Make Sheet Pan Chicken Fajitas
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). Line a large sheet pan with parchment paper or aluminum foil for easy cleanup.
Step 2: Prepare the Ingredients
Slice the chicken into thin, even strips. Slice bell peppers and onion into similar-sized pieces to ensure even roasting.
Step 3: Make the Fajita Seasoning
In a small bowl, whisk together olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, pepper, and lime juice.
Step 4: Toss Everything Together
Add chicken, peppers, and onions directly onto the sheet pan. Pour the seasoning mixture over everything and toss until well coated.
Step 5: Roast
Spread ingredients into an even layer. Bake for 18–22 minutes, stirring halfway, until the chicken is fully cooked and vegetables are tender.
Step 6: Optional Broil
For lightly charred edges, broil for 2–3 minutes at the end.
Step 7: Serve
Serve hot with warm tortillas and your favorite toppings.
