How to Make Sheet Pan Chicken Fajitas (Step-by-Step)
Here’s how to bring this delicious one-pan dinner together:
1. Preheat your oven
Preheat to 400°F (200°C). Line a large sheet pan with parchment paper or foil for easy cleanup.
2. Prep your ingredients

Slice chicken breasts, bell peppers, and red onion into thin strips. Try to keep everything similar in size so they cook evenly.
3. Season & toss
In a large bowl, combine chicken and vegetables. Drizzle with olive oil and sprinkle in the chili powder, cumin, paprika, garlic powder, salt, and pepper. Toss well to coat.
4. Bake

Spread the mixture evenly on your sheet pan. Bake for 20–25 minutes, tossing halfway through, until chicken is cooked through and vegetables are slightly charred.
5. Serve

Squeeze fresh lime juice over the top. Serve in warm tortillas with your favorite toppings.
💡 Pro Tip: Warm your tortillas by wrapping them in foil and placing them in the oven during the last 5 minutes of baking.
