How to Make Sheet Pan Chicken Fajitas

Quick Overview

These Sheet Pan Chicken Fajitas are incredibly easy to make. Everything cooks together on one tray, which means fewer dishes and more flavor. With just 10 minutes of prep and 15–18 minutes of baking, you’ll have a juicy, colorful, satisfying dinner ready in under 30 minutes.

Key Ingredients for Sheet Pan Chicken Fajitas

For the Chicken & Veggies

• 1 lb (450g) chicken breast, thinly sliced
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 green bell pepper, sliced
• 1 medium red onion, sliced
• 2 tbsp olive oil

Fajita Seasoning

• 1 tsp chili powder
• 1 tsp paprika
• 1 tsp cumin
• ½ tsp garlic powder
• ½ tsp onion powder
• ½ tsp salt
• ¼ tsp black pepper
• ¼ tsp oregano
• Optional: pinch of cayenne for heat

For Serving

• Flour or corn tortillas
• Fresh lime wedges
• Cilantro
• Sour cream
• Salsa
• Shredded cheese

Step-by-Step Instructions

Step 1 — Preheat the Oven
Preheat your oven to 425°F (220°C). This high heat helps caramelize the veggies and keeps the chicken juicy.

Step 2 — Prep the Chicken & Vegetables
Slice the chicken, peppers, and onions into thin strips. Make sure everything is roughly the same size for even cooking.

Step 3 — Season Everything
Place the chicken and vegetables on a large sheet pan. Drizzle with olive oil, then sprinkle all the fajita seasonings on top. Toss everything together until fully coated.

Step 4 — Spread Evenly on the Pan
Make sure the ingredients are spread in a single layer — this helps everything roast and caramelize instead of steaming.

Step 5 — Bake
Bake for 15–18 minutes, flipping halfway through. The chicken should be cooked through and the vegetables slightly tender with roasted edges.

Step 6 — Finish and Serve
Squeeze fresh lime juice over the fajitas. Serve with warm tortillas and your favorite toppings.

Dinner is ready — time to enjoy!
