Ingredients You’ll Need

All you need are a handful of fresh, vibrant ingredients plus the right blend of spices to transform everyday chicken and veggies into a restaurant-worthy feast. Each element adds its own splash of color, a boost of taste, or a note of essential texture to these Sheet Pan Chicken Fajitas.

• Avocado or olive oil: This adds richness, prevents sticking, and brings a touch of healthy fat to the sheet pan mix.
• Boneless skinless chicken breasts: Tender strips of lean chicken are the perfect canvas for fajita flavors.
• Red bell pepper: Sweet and vibrant, red peppers give the dish a brilliant pop of color.
• Yellow bell pepper: Their mellow sweetness balances out the spice and enhances the presentation.
• White onion: Sliced thin, it caramelizes beautifully in the oven for a hint of natural sweetness.
• Chili powder: The backbone of classic fajita seasoning, bringing gentle heat and deep earthiness.
• Ground cumin: Adds a warm, smoky undertone that ties all the flavors together.
• Oregano (rubbed between palms): Rubbing releases the oils for a bright, herbal note.
• Granulated garlic: Infuses the mix with savory depth without overpowering the other spices.
• Onion powder: Rounds out the fajita seasoning for extra punch.
• Smoked paprika: Just a bit goes a long way, bringing subtle smokiness and vivid color.
• Salt and freshly ground black pepper: Always season to taste for the best results.
• Chopped cilantro: Scattered at the end for an herby, zippy finish.
• Lime: A squeeze over the hot pan lifts all the flavors with bright, citrusy zing.
• Tortillas and toppings: Choose your favorites for serving, like salsa, sour cream, guacamole, or shredded cheese.

How to Make Sheet Pan Chicken Fajitas

Step 1: Prep Your Oven and Pan

Start by preheating your oven to a toasty 425° F, which ensures everything roasts quickly for that irresistible caramelized edge. Give your sheet pan a quick drizzle of oil or line it with foil or parchment paper for fuss-free cleanup later.

Step 2: Slice Everything Evenly

Grab your chicken breasts, bell peppers, and onion, and get slicing! Cut everything into thin strips or half-moons that are roughly the same thickness — this is the ticket to perfectly even cooking, so every bite of Sheet Pan Chicken Fajitas is juicy and tender, never dry or mushy.

Step 3: Mix Up the Fajita Seasoning

In a small bowl, combine your chili powder, cumin, oregano (freshly rubbed!), granulated garlic, onion powder, smoked paprika, salt, and pepper. This blend creates an aromatic, deeply flavored seasoning that makes your kitchen smell like a festive cantina as soon as it hits the hot pan.

Step 4: Arrange and Season on the Pan

Spread your sliced peppers and onions over one half of the prepared sheet pan, and the chicken strips over the other side. Sprinkle the fajita seasoning and chopped cilantro evenly across everything, then drizzle with the remaining oil for even coverage.

Step 5: Toss and Bake

Use your hands or tongs to give everything a good toss right on the pan, making sure every piece is coated in spices and oil. Spread the mixture into a single, even layer for the best caramelization. Slide the pan into the oven and bake for 15 to 20 minutes, until the chicken is cooked through and the veggies are just tender at the edges.

Step 6: The Finishing Touch

Pull the sizzling Sheet Pan Chicken Fajitas from the oven and immediately squeeze fresh lime juice over the hot chicken and veggies. This last step brings every flavor to life! Serve straight from the pan with warm tortillas and all your favorite toppings.

How to Serve Sheet Pan Chicken Fajitas

Garnishes

For a truly fiesta-worthy finish, pile your Sheet Pan Chicken Fajitas high with fresh extras. A shower of chopped cilantro brings color and pop, while sliced avocado, crumbled cotija cheese, or a dollop of sour cream add creaminess. Pickled jalapeños or diced tomatoes also make vibrant garnishes.

Side Dishes

Round out your fajita night with simple sides: fluffy cilantro-lime rice, silky refried beans, or a crunchy jicama slaw provide freshness alongside the warm, spicy filling of your Sheet Pan Chicken Fajitas. A side of tortilla chips with salsa doesn’t hurt, either.

Creative Ways to Present

Take things beyond tortillas by stuffing your Sheet Pan Chicken Fajitas into crisp lettuce cups for a lighter twist or piling them on top of nachos for a party platter. You can even turn leftovers into a fajita-inspired salad or quesadillas for a second meal that’s just as irresistible.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have extra Sheet Pan Chicken Fajitas, store the chicken and veggies together in an airtight container in the refrigerator for up to 3 days. Keep tortillas and toppings separate for the freshest texture when you enjoy them again.

Freezing

Sheet Pan Chicken Fajitas freeze surprisingly well! Cool everything completely, then transfer the chicken and vegetables to freezer bags or containers. These can be stored for up to 2 months. Thaw in the fridge before reheating for the best results.

Reheating

To bring your fajitas back to life, simply warm the chicken and veggies in a skillet over medium heat, stirring occasionally. Or, spread them out on a sheet pan and bake at 350° F until hot. This helps recapture that just-roasted flavor and texture.

FAQs

Can I use chicken thighs instead of breasts?

Absolutely! Chicken thighs will turn out even juicier and have richer flavor. Just slice them thinly and follow the same instructions. They may need an extra minute or two in the oven.

Can I prep Sheet Pan Chicken Fajitas ahead of time?

Definitely. You can slice all your chicken and vegetables and combine them with the spices and oil the night before. Store everything in a zip-top bag in the fridge, then simply spread on a pan and bake when it’s fajita time.

What toppings go best with fajitas?

Classic toppings like shredded cheese, guacamole, sour cream, salsa, or fresh pico de gallo are always crowd-pleasers. Don’t forget fresh lime wedges and cilantro for extra zest and brightness.

How do I know when the chicken is cooked through?

The chicken should reach an internal temperature of 165° F and be opaque all the way through. If you’re using a meat thermometer, check the thickest piece at the 15-minute mark and give it a minute or two more as needed.

Can I make Sheet Pan Chicken Fajitas spicy?

Yes! Add a pinch of cayenne pepper or diced fresh jalapeño to the spice mix for extra heat. You can also serve with spicy salsa or hot sauce for those who love to turn up the temperature.
