Ingredients You’ll Need

The beauty of these Sheet Pan Chicken Fajitas lies in their simple, real-food ingredients that work together to create a fiesta of flavor and color! Each addition—spices to veggies to garnishes—brings texture and personality to every sizzling bite.

• Boneless skinless chicken breasts: Tender strips that soak up all the bold spices and stay juicy in the oven. Slice against the grain for melt-in-your-mouth texture.
• Bell peppers (green, yellow, red): Using a mix of colors brings natural sweetness and a vibrant look—you eat with your eyes first!
• Yellow onion: Aim for thinly sliced so it caramelizes and blends smoothly with the peppers.
• Garlic: Fresh minced garlic infuses the fajitas with classic Tex-Mex aroma and depth.
• Oil (vegetable or canola): Helps everything roast beautifully and keeps the chicken tender.
• Lime: That squeeze at the end makes all the savory flavors pop and brightens everything up.
• Fresh cilantro: A finishing sprinkle for that extra burst of freshness!
• Small flour tortillas: Soft, pillowy wraps that hold all the fillings (corn tortillas work too if you prefer).
• Fajita toppings (sour cream, avocado, pico de gallo, shredded cheese): These are your fajita’s finishing touches—go as classic or creative as you like!
• Fajita seasoning (chili powder, paprika, cumin, onion powder, garlic powder, dried oregano, cayenne, salt, pepper): Whip up your own blend for trumped-up flavor—plus, you control the spice.

Variations

These Sheet Pan Chicken Fajitas are endlessly versatile! They’re a dream to customize—swap a few ingredients to suit your family’s tastebuds, squeeze in extra veggies, or go meatless. Don’t be afraid to throw your spin on it.

• Spice Swap: Dial up the heat by adding extra cayenne—or leave it out for sensitive palates and serve hot sauce on the side.
• Vegetarian Option: Toss in sliced mushrooms, sweet potatoes, or black beans instead of chicken for a hearty, colorful plant-based version.
• Switch-Up the Protein: Try thinly sliced steak or shrimp for a fun twist and slightly different flavor vibe.
• Corn Tortillas: Go gluten-free and use warm corn tortillas for serving instead of flour tortillas.
• Add-Ons Galore: Charred jalapeños, pickled onions, or even a squeeze of Mexican crema make these fajitas unique to you.

How to Make Sheet Pan Chicken Fajitas

Step 1: Prep Your Sheet Pan & Slice Everything

Give your largest sheet pan a light mist of nonstick spray (or line with parchment for easy cleanup). Slice the chicken breasts against the grain into ½-inch strips—this ensures tender bites. Next, core and slice your colorful bell peppers and thinly slice your onion for maximum sweetness once roasted.

Step 2: Season, Toss & Arrange

In a small bowl, stir together your homemade fajita seasoning spices. Scatter the sliced veggies evenly across the sheet pan, then layer the chicken strips on top. Sprinkle most of the spice blend over the chicken, a little on the veggies, spoon over the fresh garlic, and drizzle the oil everywhere. Use clean hands or tongs to toss everything on the pan so it’s all gleaming and coated, then spread into a nice even layer so everything roasts evenly.

Step 3: Roast It Up

Slide your pan into a preheated 425°F oven. Roast for about 15–20 minutes, or until the chicken is cooked through (165°F if you check with a thermometer), and veggies look irresistibly tender and just a little charred. For perfectly steamy tortillas, wrap them in foil and pop them in the oven for the last 5 minutes to warm.

Step 4: Finish with Lime & Cilantro

Remove your sizzling pan from the oven and immediately squeeze fresh lime juice all over for a bright punch of flavor. Shower with chopped cilantro for that signature fajita freshness. Serve right away in warm tortillas with your pick of fabulous toppings.

How to Serve Sheet Pan Chicken Fajitas

Garnishes

The absolute joy of Sheet Pan Chicken Fajitas? You get to pile on ALL your favorite fixings: think cool sour cream, creamy avocado, snappy pico de gallo, and a handful of shredded cheese. Even a sprinkle of fresh cilantro or a squeeze of extra lime takes everything up a notch—feel free to let everyone build their own masterpiece!

Side Dishes

Round out your fajita feast with easy sides like fluffy cilantro-lime rice, spiced black beans, or classic Mexican street corn. Even a simple green salad adds a lovely refreshing contrast to all that sizzle.

Creative Ways to Present

For a taco-bar vibe, lay out the piping hot sheet pan surrounded by little bowls of toppings so guests can create their own. Or tuck everything into lettuce cups for a light, gluten-free twist. Mini sheet pans for individual portions are fun for parties—and totally Instagram-worthy!

Make Ahead and Storage

Storing Leftovers

Leftover Sheet Pan Chicken Fajitas keep beautifully! Let everything cool down, then pop chicken and veggies into airtight containers. They’ll stay fresh in the fridge for up to 3–4 days, ready for quick lunches or dinners all over again.

Freezing

Want to meal prep for busy weeks? Freeze raw seasoned chicken and sliced veggies together in a zip-top bag. Thaw in the fridge overnight when ready to use—spread on a pan and bake as usual! Or freeze cooked leftovers in single-serve portions for fajita fixings anytime.

Reheating

For the freshest taste, reheat fajitas on a hot skillet or in the oven at 350°F until piping hot—this keeps the chicken juicy and perks the peppers right up. A quick microwave zap works for single servings (just don’t overdo it or the chicken can dry out).
