Sheet Pan Chicken Fajitas

I make these Sheet Pan Chicken Fajitas when I want a colorful, flavor-packed dinner without spending hours in the kitchen. Everything roasts together on one pan, which makes cleanup simple and the flavors blend beautifully. The chicken turns juicy and tender, while the peppers and onions become perfectly caramelized.

Why You’ll Love This Recipe

I love this recipe because it’s quick, easy, and incredibly satisfying. I only need one sheet pan, which means fewer dishes and less mess. I can prepare everything in about 10 minutes, then let the oven do the work. I also enjoy how versatile it is—I can serve it in tortillas, over rice, or on top of a salad. The bold fajita seasoning gives every bite a smoky, slightly spicy flavor that I crave.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 1 1/2 pounds boneless, skinless chicken breasts, sliced into strips

• 3 bell peppers (any colors), sliced

• 1 large onion, sliced

• 3 tablespoons olive oil

• 1 tablespoon chili powder

• 1 teaspoon ground cumin

• 1 teaspoon smoked paprika

• 1/2 teaspoon garlic powder

• 1/2 teaspoon onion powder

• 1/2 teaspoon dried oregano

• 1/2 teaspoon salt

• 1/4 teaspoon black pepper

• Juice of 1 lime

• Flour or corn tortillas, for serving

• Optional toppings: sour cream, shredded cheese, guacamole, salsa, chopped cilantro

Directions

1. I preheat the oven to 400°F (200°C) and lightly grease a large sheet pan or line it with parchment paper.

2. I slice the chicken, bell peppers, and onion into even strips so they cook evenly.

3. I place the chicken and vegetables on the sheet pan.

4. In a small bowl, I mix olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and pepper.

5. I pour the seasoning mixture over the chicken and vegetables, then toss everything together directly on the pan to coat evenly.

6. I spread everything out in a single layer to ensure proper roasting.

7. I bake for 20–25 minutes, or until the chicken is cooked through and the vegetables are tender.

8. I squeeze fresh lime juice over the top before serving.

9. I serve the fajita mixture in warm tortillas with my favorite toppings.

Prep time: 10 minutes
Cook time: 20–25 minutes
Total time: about 35 minutes

Variations

I sometimes swap chicken breasts for boneless chicken thighs for extra juiciness. When I want more heat, I add sliced jalapeños or a pinch of cayenne pepper. If I’m looking for a lower-carb option, I serve the fajitas in lettuce wraps instead of tortillas. I also enjoy adding sliced mushrooms or zucchini to the sheet pan for extra vegetables.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. When I reheat, I usually warm everything in a skillet over medium heat until heated through. I can also microwave it in short intervals, stirring in between to ensure even heating. If I plan to freeze it, I let the mixture cool completely and store it in a freezer-safe container for up to 2 months.

FAQs

Can I make this recipe ahead of time?

I often slice the vegetables and chicken ahead of time and store them separately in the refrigerator. When I’m ready to cook, I simply season and bake.

Can I use store-bought fajita seasoning?

I sometimes use a pre-made seasoning blend when I’m short on time. I adjust the salt level depending on the brand I use.

How do I know when the chicken is fully cooked?

I check that the internal temperature reaches 165°F (74°C). I also make sure the juices run clear and there’s no pink in the center.

Can I make this recipe in a skillet instead?

I can cook everything in a large skillet over medium-high heat. I cook the chicken first, then add the vegetables and seasonings until everything is tender and cooked through.

What toppings work best with these fajitas?

I like topping mine with sour cream, shredded cheese, guacamole, salsa, and fresh cilantro. I sometimes add a squeeze of extra lime juice for brightness.
