Sheet Pan Chicken Fajitas Recipe

There’s something about fajitas that just screams fun dinner night to me.
When I first started cooking for my family, fajitas were one of the first meals that made me feel like a real “weeknight dinner hero.”
But let’s be honest — standing over a hot skillet, flipping peppers and chicken constantly, after a long day? Not my idea of relaxing.

That’s when I discovered the beauty of Sheet Pan Chicken Fajitas — all the flavors we love, without the fuss.
Everything cooks at once on one tray: juicy chicken, sizzling peppers, tender onions, and a smoky spice blend that perfumes your whole kitchen.
Less mess, less stress — and maximum flavor.

Now, it’s a regular in my dinner rotation, and I bet it’ll become one of your go-tos too!

Ingredients You’ll Need

Here’s everything you need for the easiest sheet pan fajitas ever:

For the Fajitas:

• 1 ½ pounds boneless, skinless chicken breasts or thighs, sliced into thin strips
• 3 bell peppers, sliced (use a mix of colors for prettiness!)
• 1 large red onion, thinly sliced
• 2 tablespoons olive oil
• Juice of 1 lime
• 8 small flour tortillas (or corn tortillas)

For the Seasoning:

• 1 ½ teaspoons chili powder
• 1 teaspoon smoked paprika
• 1 teaspoon ground cumin
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• Optional: pinch of cayenne pepper (for heat)

For Toppings (Optional):

• Sour cream or Greek yogurt
• Shredded cheese
• Guacamole or sliced avocado
• Fresh cilantro
• Extra lime wedges

Ingredient Notes and Substitutions:

• Chicken thighs: More flavorful and juicy, but breasts work great too.
• Vegetables: Add mushrooms, zucchini, or even thinly sliced carrots if you want.
• Low-carb option: Serve the chicken and veggies in lettuce wraps instead of tortillas.

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 425°F (220°C).
Line a large sheet pan with parchment paper or foil for easy cleanup.

2. Slice Everything

Cut chicken, peppers, and onions into even strips so they cook evenly.

3. Season and Toss

In a large bowl, combine chicken, peppers, onions, olive oil, lime juice, and all the seasonings.
Toss well until everything is evenly coated.

Tip: Don’t be shy with the seasoning — it’s what gives that classic fajita flavor!

4. Arrange on the Sheet Pan

Spread the chicken and veggies out in a single layer on the prepared sheet pan.
Make sure it’s not too crowded — use two pans if needed.

5. Bake

Bake for 18–22 minutes, stirring halfway through, until the chicken is cooked through and the veggies are tender and slightly charred.

Pro Tip: For a little extra caramelization, broil for the last 2–3 minutes!

6. Warm Tortillas

While the fajitas bake, warm your tortillas either in the microwave, on a skillet, or wrapped in foil in the oven.

7. Serve

Pile the sizzling chicken and veggies into tortillas, add your favorite toppings, and dig in!

Expert Tips for Success

• Cut everything evenly: This ensures the chicken and veggies cook at the same rate.
• Use a HOT oven: 425°F creates those perfect little charred edges.
• Don’t overcrowd the pan: If everything’s piled up, it’ll steam instead of roast.
• Fresh lime juice at the end: A final squeeze brightens up all the smoky flavors.

Variations and Substitutions

• Steak Fajitas: Swap chicken for thinly sliced flank steak; reduce bake time to about 12–15 minutes.
• Shrimp Fajitas: Use large raw shrimp; add them to the pan during the last 7–8 minutes of cooking.
• Vegetarian Fajitas: Skip the chicken and add more hearty veggies like mushrooms, squash, and black beans.
• Spicy Fajitas: Add extra cayenne or sliced jalapeños to the mix.

Serving Suggestions

• Side of Mexican Rice or Cilantro Lime Rice
• Refried Beans or Black Beans
• Tortilla chips with salsa or queso dip
• Simple green salad with avocado dressing

Fun Tip: Set up a fajita bar! Lay out tortillas, toppings, and sauces so everyone can customize their dinner.

Storage and Reheating Tips

• Storage: Store leftover chicken and veggies in an airtight container in the fridge for up to 4 days.
• Reheating: Reheat in a skillet over medium heat until warmed through, or microwave in short bursts.
• Freezing: You can freeze the cooked fajita mix (minus the tortillas) for up to 2 months. Thaw overnight in the fridge before reheating.

Recipe FAQs

Can I make this ahead of time?
Absolutely! Slice everything and toss it with oil and seasoning. Store it in the fridge until you’re ready to bake.

Can I use pre-cooked chicken?
Sure, but reduce the baking time. Add the cooked chicken after 10 minutes of baking the veggies, so it doesn’t dry out.

What’s the best way to warm tortillas?
I love wrapping them in foil and popping them in the oven for a few minutes, but you can also quickly toast them over a gas burner for that charred effect!

Can I add cheese before baking?
I recommend adding cheese after baking — that way it melts fresh and gooey when you assemble your fajitas.
