What Kind of Chicken Should I Use?

Boneless, skinless chicken breasts or thighs both work beautifully here. Chicken thighs will be juicier and a bit more flavorful, while breasts keep things lean. Slice your chicken into thin strips to help everything cook evenly and soak up all those delicious spices.

Ingredients for the Sheet Pan Chicken Fajitas

Chicken breasts or thighs – The star protein, thinly sliced to roast quickly and evenly.

Bell peppers (red, yellow, green) – For vibrant color and sweet crunch.

Red onion – Adds sharp flavor and a bit of natural sweetness once roasted.

Olive oil – Helps everything crisp up and keeps the seasoning in place.

Fajita seasoning – A blend of chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper for that signature Tex-Mex flair.

Lime – A fresh squeeze right before serving brightens up the dish.

Flour tortillas – Soft and warm, ready to cradle your juicy fajita filling.

Optional toppings – Sour cream, guacamole, shredded cheese, jalapeños, chopped cilantro.

How To Make the Sheet Pan Chicken Fajitas

Step 1: Prep Your Ingredients

Start by preheating your oven to 425°F (220°C). Slice your chicken into thin strips, and do the same for your bell peppers and red onion. This ensures everything roasts evenly and gets beautifully caramelized edges.

Step 2: Season Everything

In a large mixing bowl, toss the chicken, bell peppers, and onion with olive oil and fajita seasoning. Make sure everything is evenly coated—this step is key for getting that bold, savory flavor in every bite.

Step 3: Spread on a Sheet Pan

Line a large sheet pan with parchment paper or foil for easy cleanup. Spread the chicken and veggie mixture in a single layer. Avoid overcrowding the pan so everything roasts instead of steaming.

Step 4: Roast to Perfection

Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender with slightly crisp edges. Halfway through, you can give everything a gentle toss for even roasting.

Step 5: Warm the Tortillas

While the chicken and veggies are roasting, wrap your tortillas in foil and warm them in the oven for the last 5 minutes of cooking. Alternatively, you can warm them in a skillet for a bit of char.

Step 6: Serve and Enjoy

Remove everything from the oven and give it a squeeze of fresh lime juice. Serve hot with your favorite toppings: sour cream, guacamole, shredded cheese, jalapeños, or a sprinkle of fresh cilantro.

How to Serve and Store Sheet Pan Chicken Fajitas

These sheet pan chicken fajitas are best served hot, straight from the oven. Lay out warm tortillas, bowls of toppings, and let everyone build their perfect fajita. It makes dinner feel like a fun, interactive event. For a full Tex-Mex spread, pair with Mexican rice, refried beans, or a simple corn salad.

To store leftovers, let everything cool completely before transferring to an airtight container. They’ll keep in the fridge for up to 4 days. Reheat in a skillet over medium heat for best texture, or use the microwave for a quick fix. The filling also makes a great topping for nachos or a stuffing for quesadillas.

Frequently Asked Questions

Can I use frozen chicken?

Yes, but be sure to fully thaw it before slicing and seasoning. This helps everything cook evenly and avoids excess moisture on the pan.

Are corn tortillas okay instead of flour?

Absolutely! Corn tortillas bring a slightly nuttier flavor and are naturally gluten-free.

What if I don’t have fajita seasoning?

You can easily make your own with 1 tsp each of chili powder and cumin, 1/2 tsp paprika, garlic powder, onion powder, salt, and pepper.

Can I make this spicier?

Definitely. Add cayenne pepper or sliced jalapeños into the sheet pan mix, or drizzle with hot sauce before serving.

How do I keep tortillas warm for a crowd?

Wrap them in foil and keep them in a warm oven (around 200°F) until ready to serve.

Can I freeze the leftovers?

Yes, the cooked filling freezes well. Let it cool, portion it into freezer-safe bags, and reheat straight from frozen in a skillet or microwave.
