Ingredients For Making Sheet Pan Chicken Fajitas

Scroll down to the recipe card to see the complete list of ingredients.

Chicken. You can use chicken breasts or chicken tenderloins to make these fajitas. I have also used chicken thighs in the past, and even though they still come out delicious, I find that they render too much fat in the pan.
Vegetables. Bell peppers and onion are the traditional veggies that are served with most fajitas. I love using bell peppers that have bright colors like yellow, red, or green. As for the onion, use white or yellow.
Oil. We use it in this recipe so the fajita seasoning adheres well to the chicken and veggies.
Fajita seasoning. Make your own by blending paprika, chili powder, cayenne pepper (to add a lil’ kick), cumin, garlic powder, onion powder, oregano, salt, and pepper.
Lime juice. It adds a slight citrus flavor to the fajitas.
Tortillas. Serve them with flour or corn tortillas.
Toppings. Serve these amazing fajitas with your favorite toppings like chopped cilantro, avocado, guacamole, salsa, sour cream, or crema fresca.

Frequently Asked Questions

Can I make sheet pan chicken fajitas ahead of time?

One of the best things about this recipe is that it works great for meal prep. Just slice the bell peppers and the onion, cut the chicken breasts into strips, and store everything inside a resealable bag. This way, you can keep the sealed ingredients in the refrigerator overnight or store them in the freezer for up to three months.

As for the fajita seasoning, mix all of the spices and store them in a jar at room temperature. They will stay fresh for months! Double, triple, or quadruple the recipe for the seasoning always to have it on hand.

What other ingredients can I add to chicken fajitas?

Use your favorite veggies like jalapeños, tomatoes, other types of onion, yellow squash or zucchini, and even mushrooms.

Also, feel free to omit or change any of the recipe’s ingredients. Make them with beef, pork, and/or shrimp. Want to make them vegetarian? Skip the chicken and add other veggies or your favorite beans.

What sides or toppings can I serve with chicken fajitas?

As with most Mexican-inspired dishes, these go well with Cilantro Lime Rice, Green Rice, or Rice With Peas and Carrots.
Serve them with corn or flour tortillas.

💡 Tips For Success

Use a large baking sheet covered with foil or parchment paper for easy cleanup.

If you want to go for a charred look, you can leave them in the oven for a few minutes longer or put them under the broiler for 2-3 minutes. Just try not to bake them for too long so the chicken doesn’t dry out.

The ingredients I’m using for the fajita seasoning are amazing, but feel free to use your favorite fajita seasoning mix from the grocery store.
