Sheet Pan Chicken Fajitas

What Are Sheet Pan Chicken Fajitas

Fajitas are a mix of seasoned meat and vegetables, usually served with tortillas. In this version, everything bakes together on one Sheet pan. You don’t need a skillet or multiple pans.

The chicken gets juicy and tender in the oven, while the peppers and onions soften and caramelize. The spice mix adds smoky, bold flavor without much work.

You can serve them with tortillas, rice, or salad whatever you like. It’s a full meal with protein, vegetables, and healthy carbs.

Ingredients You’ll Need

You don’t need many ingredients to make this recipe. Most are probably in your kitchen already.

For the Chicken and Vegetables

• 1 pound boneless, skinless chicken breast, sliced thin
• 2 bell peppers, any color, sliced
• 1 large red onion, sliced
• 2 tablespoons olive oil
• Salt and pepper to taste

For the Fajita Seasoning

• 1 teaspoon chili powder
• 1 teaspoon paprika
• ½ teaspoon cumin
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ¼ teaspoon cayenne pepper (optional for heat)

For Serving

• Warm flour or corn tortillas
• Lime wedges
• Fresh cilantro

How to Make Sheet Pan Chicken Fajitas

Follow these easy steps. You’ll have dinner on the table in less than 30 minutes.

Step 1: Preheat and Prepare

Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or foil for easy cleanup.

Slice chicken, peppers, and onions into thin strips. Try to keep them even so they cook at the same speed.

Step 2: Season Everything

In a large bowl, combine the chicken, peppers, and onions. Drizzle with olive oil. Sprinkle all the fajita seasoning on top. Mix well so every piece is coated evenly.

If you prefer, you can mix the seasoning separately first, then add it to the bowl.

Step 3: Arrange on the Pan

Spread the seasoned mixture on the sheet pan in a single layer. Don’t crowd the pan — everything should have space to roast, not steam.

If your pan is small, use two pans or cook in batches.

Step 4: Bake

Bake for 20–25 minutes, or until the chicken is cooked through and the vegetables are soft and slightly browned at the edges.

If you want a little char, broil for 2–3 minutes at the end. Watch closely so it doesn’t burn.

Step 5: Serve

Squeeze fresh lime juice over the top. Serve the chicken and veggies in warm tortillas with your favorite toppings cheese, sour cream, salsa, or avocado.

That’s it. Dinner done with one pan and no mess.
