Ingredients & Why They Work

The ingredients in this Easy Sheet Pan Chicken Fajitas Recipe are super straightforward but work beautifully together to create that perfect balance of juicy, tender chicken with sweet and slightly smoky peppers. When shopping, try to grab fresh, colorful bell peppers and a good-quality Greek yogurt for the sauce to really make a difference.

• Boneless chicken breasts: Thinly sliced for quick, even cooking and juicy bites.
• Salted butter or olive oil: Adds richness and helps the chicken and veggies get that lovely roasted char.
• Garlic: Freshly chopped, it brightens the whole dish with that savory punch.
• Taco seasoning: A blend of spices that you can make yourself, giving complete control over heat and flavor.
• Yellow onion: Sliced to sweetness, it softens and caramelizes during roasting.
• Bell peppers & poblano pepper: Colorful, fresh, and juicy to add crunch and depth with every bite.
• Tortillas: Warmed to soften and hold all that delicious filling perfectly.
• Avocado, limes, cilantro: Classic toppings that add creaminess, zest, and fresh herbal notes.
• Cotija Verde Sauce ingredients: Combining Greek yogurt, mayo, salsa verde, pickled jalapeños, cilantro, and cotija cheese creates a creamy, tangy topping that balances the smoky heat.

Make It Your Way

I love how this Easy Sheet Pan Chicken Fajitas Recipe invites you to make it your own. Whether you want to turn up the heat, make it vegetarian, or swap in some of your favorite peppers, it’s super flexible. Even the toppings are your playground.

• Variation: Sometimes I swap chicken for thinly sliced flank steak — totally delicious and cooks just as quickly.
• Spice Level: You can easily dial up the heat by adding more pickled jalapeños to the verde sauce or tossing a dash of cayenne in your taco seasoning.
• Veggie Boost: Adding sliced mushrooms or zucchini along with the peppers gives extra texture and nutrition without much extra effort.
• Gluten-Free: Use corn tortillas instead of flour to keep it naturally gluten-free, and you’re good to go.

Step-by-Step: How I Make Easy Sheet Pan Chicken Fajitas Recipe

Step 1: Prep the Oven and Chicken

First things first, preheat your oven to 425°F (220°C). While it’s warming up, thinly slice your chicken breasts into strips about a half-inch thick. Toss the chicken on a large sheet pan with your chosen fat—salted butter or olive oil—along with the chopped garlic, taco seasoning, salt, and pepper. Make sure every piece is nicely coated. This is where the magic starts, as the seasoning sticks to the chicken and infuses flavor during roasting.

Step 2: Add the Veggies and Season

Next, slice your yellow onion, bell peppers, and poblano pepper into thin strips. Season them lightly with salt and pepper, then toss everything together right on the pan with the chicken. Spread out the mixture evenly—you want space for the heat to circulate so the chicken cooks quickly and the veggies get those lovely charred edges.

Step 3: Roast to Perfection

Pop the sheet pan in the oven and roast for 20 to 25 minutes. I usually check around 20 minutes—your chicken should be cooked through (juices run clear) and the peppers should have nicely softened with some charred bits for extra flavor. If you notice the veggies aren’t quite there yet, give it a few more minutes but watch closely to avoid burning the garlic.

Step 4: Whip Up the Cotija Verde Sauce

While the fajitas are roasting, mix the Cotija Verde Sauce by combining Greek yogurt, mayo (or more Greek yogurt if you prefer), salsa verde, chopped pickled jalapeños, and cilantro in a bowl. Season with a pinch of salt to balance the tang and heat. This sauce brings a creamy kick every time, and it’s honestly one of my favorite parts of the whole meal.

Step 5: Assemble and Enjoy

When everything’s cooked, warm your tortillas just until they’re soft and pliable. Pile on the chicken, roasted peppers, and onions, then drizzle with your Cotija Verde Sauce. Finish with slices of fresh avocado, a sprinkle of cilantro, a squeeze of lime, and a few crumbles of cotija cheese. Grab a fork (or just go all in with your hands) and enjoy the fiesta you just made!

How to Serve Easy Sheet Pan Chicken Fajitas Recipe

Garnishes

I always top my fajitas with a squeeze of fresh lime because the acidity really brightens the dish. Fresh cilantro adds that vivid herbal note I can’t live without, and creamy slices of ripe avocado bring a buttery contrast. The cotija cheese sprinkled on top is my secret ingredient—it adds a salty tang that’s irresistible. If you like a little extra heat, I sometimes add a few pickled jalapeños or a drizzle of hot sauce.

Side Dishes

I love pairing these fajitas with a side of Mexican street corn salad or a simple black bean and corn salad. Sometimes, I serve a bowl of cilantro-lime rice or just some tortilla chips to scoop up any leftover sauce and fillings. A crisp green salad with a citrus dressing also complements the smoky fajita flavors beautifully.

Creative Ways to Present

For a fun twist at parties, I’ve served this recipe as a fajita bar where friends can build their own with various toppings laid out buffet-style. Another favorite is stuffing the mix into tostada shells for a crunchy bite. If you want to keep it casual but pretty, try serving everything on a big wooden board with tortillas wrapped in a kitchen towel to keep them warm and soft.

Make Ahead and Storage

Storing Leftovers

I like to separate the cooked chicken and veggies from the tortillas before storing. Keep the filling in an airtight container in the fridge for up to 3 days. The tortillas I wrap tightly in foil or plastic wrap to prevent drying out. This way, both stay fresh, and you don’t end up with soggy tortillas.

Freezing

If you want to freeze the filling, make sure it’s cooled completely, then pack it into a freezer-safe container or bag. It freezes well for up to 2 months. Just thaw it overnight in the fridge before reheating. I usually avoid freezing the tortillas because they don’t always thaw with the best texture.

Reheating

To reheat the chicken and peppers, I spread them in a single layer on a baking sheet and warm them in a 350°F oven for about 10-12 minutes until heated through—this keeps them from getting mushy. For tortillas, I wrap them in foil and warm them in the oven or quickly heat them on a skillet for a minute each side to keep them soft and pliable.
