Ingredients You Need for Sheet Pan Chicken Fajitas

Here’s what you’ll need to make my favorite Sheet Pan Chicken Fajitas:

For the Fajitas:

• 1½ pounds boneless, skinless chicken breasts, sliced into strips
• 3 bell peppers (I love using red, yellow, and green for color)
• 1 large yellow onion, thinly sliced
• 2 cloves fresh garlic, minced
• 3 tablespoons olive oil or vegetable oil
• 1 fresh lime
• ¼ cup fresh cilantro, chopped
• 8-10 small flour tortillas

For the Homemade Fajita Seasoning:

• 1½ teaspoons paprika
• 1½ teaspoons ground cumin
• ½ teaspoon onion powder
• ½ teaspoon garlic powder
• ¼ teaspoon dried oregano

I always use a mix of colorful bell peppers because they add such beautiful color and sweetness to the fajitas!

How to Make Sheet Pan Chicken Fajitas

Let me walk you through how I make these easy Sheet Pan Chicken Fajitas:

1. Prep your oven and pan: Preheat your oven to 425°F and lightly grease a large sheet pan with cooking spray.
2. Prepare the ingredients: Slice your chicken breasts against the grain into ½-inch strips. Core and slice your bell peppers into strips, and thinly slice your onion.
3. Arrange on the pan: Place the sliced vegetables evenly across your sheet pan, then layer the chicken strips on top.
4. Make the seasoning: In a small bowl, combine all the fajita seasoning ingredients – chili powder, paprika, cumin, onion powder, garlic powder, oregano, cayenne, salt, and pepper. Mix well.
5. Season and oil: Sprinkle most of the seasoning mixture over the chicken, with some over the vegetables. Add the minced garlic on top of the chicken, then drizzle everything with oil.
6. Toss and spread: Using your hands or tongs, toss everything together until well coated, then spread into an even layer.
7. Bake: Cook for 15-20 minutes, or until the chicken reaches an internal temperature of 165°F.
8. Warm tortillas: During the last 5 minutes of cooking, wrap your tortillas in foil and place them in the oven to warm.
9. Finish and serve: Remove from oven, squeeze fresh lime juice over everything, and sprinkle with chopped cilantro.

How I Make This Sheet Pan Chicken Fajitas Perfect Every Time

My secret to perfect Sheet Pan Chicken Fajitas is all about the details! I always make sure not to overcrowd the pan, the vegetables need space to caramelize properly.

I also slice my chicken uniformly so everything cooks evenly, and I never skip the lime juice at the end, it brightens all the flavors beautifully.

Can I make Sheet Pan Chicken Fajitas ahead of time?

I often prep all my vegetables and chicken in the morning, storing them separately in the refrigerator.

You can even make the fajita seasoning several days ahead and store it in a small jar.
