You don’t need complicated tools for this recipe — just a few reliable kitchen essentials.
Large Sheet Pan – A sturdy sheet pan allows the chicken and vegetables to roast evenly and develop delicious, caramelized edges. I recommend using a large sheet pan so the ingredients have plenty of space to cook without overcrowding.

How to Make Sheet Pan Chicken Fajitas
1. Preheat the Oven
Preheat your oven to 400°F (200°C).
2. Prepare the Chicken and Vegetables
Slice the chicken breasts into thin strips. Slice the bell peppers and onion into similar-sized strips so everything cooks evenly.
3. Season Everything
Place the chicken, peppers, and onions in a large mixing bowl. Drizzle with olive oil and sprinkle with the fajita seasoning.
Toss everything together until evenly coated.
4. Spread on the Sheet Pan
Spread the mixture in an even layer on your sheet pan.
Try not to overcrowd the pan — this allows the ingredients to roast instead of steam.

5. Roast
Bake for 18–22 minutes, or until the chicken is fully cooked and the vegetables are tender.
You can broil for the final 2 minutes if you want extra caramelization.
6. Serve
Remove from the oven and serve immediately in warm tortillas with lime wedges and your favorite toppings.
