How to Make 30 Minute Sheet Pan Chicken Fajitas: Step-by-Step Instructions

This recipe is designed for simplicity, speed, and maximum flavor with minimal cleanup. Follow each step carefully for juicy chicken, perfectly roasted veggies, and fajita flavors that will make your taste buds dance.

Step 1: Gather and Prepare Your Ingredients

Before you start cooking, assemble all your ingredients to streamline the process.

Key ingredients:

• Boneless, skinless chicken breasts or thighs (preferably thighs for more juiciness)

• Bell peppers (a mix of red, yellow, and green for color and sweetness)

• Yellow or red onion

• Olive oil

• Fresh lime juice

• Garlic powder, chili powder, cumin, smoked paprika, oregano, salt, and pepper for seasoning

• Optional: crushed red pepper flakes or cayenne for heat

Preparation tips:

• Wash and dry the vegetables thoroughly.

• Slice the bell peppers into thin strips, about ¼-inch wide.

• Slice the onion into similar-sized strips to ensure even roasting.

• Cut the chicken into thin, uniform strips (about 1/2-inch thick). Uniformity is key to ensure everything cooks evenly in the same amount of time.

Step 2: Make the Fajita Seasoning Mix

Instead of relying on store-bought mixes filled with preservatives and excess salt, prepare your own quick homemade fajita seasoning. This lets you control the flavor and heat level.

Mix together:

• 1 teaspoon chili powder

• 1 teaspoon smoked paprika

• 1 teaspoon ground cumin

• 1/2 teaspoon garlic powder

• 1/2 teaspoon onion powder

• 1/2 teaspoon dried oregano

• 1 teaspoon salt (adjust to taste)

• 1/4 teaspoon black pepper

• Optional: 1/4 teaspoon crushed red pepper flakes or cayenne for spice

Whisk these spices in a small bowl to combine.

Step 3: Toss the Chicken and Vegetables with Seasoning and Oil

In a large mixing bowl, combine the sliced chicken strips and sliced peppers and onions.

Add:

• 2 tablespoons olive oil

• The fajita seasoning mix

• Juice of half a lime (about 1 tablespoon)

Toss everything gently but thoroughly with your hands or tongs until all pieces are evenly coated with oil, seasoning, and lime juice. The lime adds brightness and helps tenderize the chicken.

Step 4: Arrange Everything on the Sheet Pan

Preheat your oven to 425°F (220°C).

Line a large rimmed sheet pan with parchment paper or aluminum foil for easy cleanup.

Spread the seasoned chicken and vegetables out in a single layer on the pan. Avoid overcrowding or piling ingredients on top of each other—this ensures they roast properly and develop nice caramelization instead of steaming.

Step 5: Roast in the Oven

Place the sheet pan on the middle rack of the preheated oven.

Bake for 18 to 22 minutes, stirring halfway through cooking.

What to look for:

• Chicken strips should be cooked through with no pink inside, reaching an internal temperature of 165°F (74°C).

• Bell peppers and onions should be tender and slightly charred at the edges, releasing their natural sweetness.

• The vegetables will soften but retain a bit of their crispness for that perfect fajita bite.

Step 6: Optional – Broil for Extra Char

If you love that smoky, charred fajita flavor, turn the oven to broil for the last 2–3 minutes of cooking.

Watch closely to prevent burning.

Broiling adds that sizzling finish reminiscent of traditional skillet-cooked fajitas.

Step 7: Finish with Fresh Lime and Cilantro

Remove the sheet pan from the oven.

Squeeze additional fresh lime juice over the chicken and veggies to brighten flavors.

Optional: sprinkle chopped fresh cilantro on top for a fresh herbal note.

Step 8: Serve with Warm Tortillas and Toppings

Serve your sheet pan chicken fajitas hot with warmed flour or corn tortillas.

Popular toppings include:

• Guacamole or sliced avocado

• Sour cream or Greek yogurt

• Salsa or pico de gallo

• Shredded cheese

• Sliced jalapeños or hot sauce

• Fresh cilantro and lime wedges

Tips for Success

• Uniform slicing: Ensures even cooking between chicken and veggies.

• High heat roasting: Promotes caramelization and flavor.

• Single layer on the pan: Prevents steaming and sogginess.

• Adjust seasoning: Customize heat and salt to taste.

• Use a meat thermometer: To avoid overcooking chicken.
