How to Make Sheet Pan Chicken Fajitas

Step 1: Prep Your Oven and Sheet Pan

Start by preheating your oven to 400 degrees. While it heats, grab the biggest baking sheet you have—this ensures everything has space to roast instead of steam. It’s a little touch that makes your Sheet Pan Chicken Fajitas perfectly caramelized every time.

Step 2: Slice and Arrange

Cut the chicken breast tenders into bite-sized pieces, then thinly slice your onion and all three peppers. Spread everything out in a single, even layer on your prepared sheet pan so each piece will roast up with plenty of golden edges.

Step 3: Olive Oil Drizzle

Drizzle the olive oil evenly over all the chicken and vegetables. This step helps every bite become juicy and full of rich, earthy flavor—and ensures your fajita filling won’t stick to the pan.

Step 4: Season and Toss

Sprinkle over the chili powder, cumin, garlic powder, paprika, dried oregano, onion powder, plus generous pinches of Kosher salt and fresh cracked pepper. Use your hands or a spatula to toss everything together, coating each piece with that irresistible spice blend.

Step 5: Roast, Stir, and Broil

Pop the pan into your hot oven and bake for 10 minutes. Give everything a quick stir (so nothing sticks or overcooks), then return to the oven for another 5 minutes. For that craveable fajita char, broil everything on high for 2-3 minutes until the edges get beautifully crispy and just a little bit caramelized.

Step 6: Serve and Savor

Pile the sizzling chicken and veggies straight from the sheet pan onto warm flour tortillas. Set out your favorite fajita toppings—think cool sour cream, zesty salsa, fresh cilantro, cheese, and lime wedges—and let everyone build their perfect bite!

Garnishes

Nothing takes Sheet Pan Chicken Fajitas from great to unforgettable like the right garnishes! Try chopped fresh cilantro for herby brightness, a squeeze of fresh lime for a citrusy zing, thinly sliced jalapeños for subtle heat, or a sprinkle of crumbled queso fresco for irresistible creaminess. Set up a toppings bar and watch everyone go wild personalizing their fajitas.

Side Dishes

Pair your Sheet Pan Chicken Fajitas with classic sides for a true Tex-Mex feast. Fluffy cilantro lime rice and smoky black beans are always winners. Or go for charred corn, creamy guacamole, or a bright, crunchy slaw to balance all those rich flavors. You honestly can’t go wrong!

Creative Ways to Present

Think beyond tortillas—this fajita filling is incredibly versatile! Spoon it over rice bowls for an easy meal prep lunch, stuff into roasted sweet potatoes, or pile onto a crunchy salad. For parties, serve it nacho-style on a big platter of tortilla chips, then layer with cheese and all the fixings for a totally crowd-pleasing sheet pan chicken fajitas twist.

Make Ahead and Storage

Storing Leftovers

If you have any leftover Sheet Pan Chicken Fajitas (doubtful, but just in case), let everything cool to room temperature, then transfer to an airtight container. Tucked away in the fridge, it’ll keep beautifully for up to 4 days—making lunches and speedy dinners a breeze.

Freezing

To freeze, simply pack the cooled fajita chicken and veggies into freezer-safe zip-top bags (squeeze out excess air). Store for up to 2 months. Thaw overnight in the fridge for best results, and your future self will thank you every single time!

Reheating

For the juiciest, most flavorful results, reheat leftover Sheet Pan Chicken Fajitas in a hot skillet or pop them back under the broiler for a minute or two. The microwave works as well, though you’ll lose a bit of that signature char—but hey, fast fajitas are still good fajitas!

FAQs

Can I use chicken thighs instead of breast tenders?

Absolutely! Chicken thighs work wonderfully in Sheet Pan Chicken Fajitas and offer even juicier, slightly richer results. Just slice them into bite-size pieces and follow the recipe as written.

What tortillas are best for serving?

Flour tortillas are traditional for fajitas because they’re soft, flexible, and soak up all the delicious juices. However, corn tortillas work great if that’s your preference or if you’re looking for a gluten-free option.

Can I add other vegetables?

Definitely—Sheet Pan Chicken Fajitas are endlessly customizable! Try adding zucchini, mushrooms, or sliced poblano peppers for extra variety and flavor.

How can I make it spicier?

To turn up the heat, add a pinch of cayenne to the spice blend or toss in sliced fresh jalapeños with the veggies before roasting. Adjust to your taste and bring the fire!

Is this recipe good for meal prep?

Yes! Sheet Pan Chicken Fajitas are stellar for meal prep. Simply portion into containers with rice or tortillas, add your favorite toppings, and you’ve got grab-and-go lunches or quick dinners ready in no time.
