What Are Fajitas?

Fajitas are a Tex-Mex dish typically made up of a stripped protein (usually chicken or beef) and stripped vegetables (bell peppers and onion) marinated in the flavors of a Mexican-inspired seasoning. They are then served in a flour or corn tortilla with toppings.

This chicken fajita recipe is made on a sheet pan for simple cooking and easy clean-up. No grilling required!

Ingredients in Sheet Pan Chicken Fajitas

Chicken tenders – I buy pre-cut chicken tenders since you’ll end up having to cut your boneless, skinless chicken breasts into strips anyway. If you cannot find pre-cut chicken tenders feel free to use boneless, skinless chicken breasts and slice them into strips.

Olive oil – for coating chicken and veggies.

Homemade fajita seasoning – chili powder, garlic powder, onion powder, cumin and salt are combined to make a fajitas seasoning for chicken. Add a pinch of cayenne pepper for a little kick of heat if desired.

Bell peppers – I use 3 varieties (red bell pepper, yellow bell pepper and green bell pepper) but feel free to use 3 of the same or different varieties.

Onion – you can use yellow or red onions but be sure to slice them for even cooking.

Flour tortillas or corn tortillas – wrap up your sheet pan chicken fajitas into tortillas! Use corn tortillas if gluten-free.

How to Make Sheet Pan Fajitas

STEP 1: MAKE HOMEMADE FAJITA SEASONING

In a large bowl combine all fajita seasoning ingredients.

STEP 2: COAT CHICKEN AND VEGETABLES

Add chicken and olive oil to fajita seasoning and toss to coat. Add in bell peppers and onion and stir to combine.

STEP 3: ROAST

Spread chicken, bell peppers and onion on a baking sheet. Bake in oven for 15 minutes. Turn on broiler and broil for 2-3 minutes or until chicken and veggies have browned. Watch carefully to ensure they don’t burn.

STEP 4: ASSEMBLE

Serve chicken and veggies in warmed tortillas with desired toppings.

What toppings do you put on a fajita?

Ultimately what toppings you put on your sheet pan chicken fajitas is up to you but here are some delicious ideas!

• Sour cream – a dollop of sour cream is always a good idea. Greek yogurt works too.
• Lime wedges – give a little squeeze of lime juice onto your fajitas before serving
• Guacamole – use store-bought or homemade. Sliced avocado is also a great option!
• Salsa – Again, you can use store-bought or homemade
• Cilantro – sprinkle a little cilantro onto your sheet pan fajitas or omit if you don’t like cilantro
• Shredded Cheese– buy pre-shredded or shred yourself. Cheddar works great or try a more traditional Mexican cheese like cotija.
• Green onions – green parts only, sliced

How to Store + Reheat Leftovers

Fridge – store your leftovers in an airtight container. Reheat in the oven, on stove top or in the microwave.

Freezer – I personally would not recommend freezing this recipe.
