Sheet Pan Chicken Fajitas Recipe

This Chicken Fajita Recipe is easy to make at home and taste just as good as a restaurant. Instead of cooking them in a large skillet on the stove, you can cook everything on a sheet pan in the oven. It’s a great way to enjoy this Mexican dish.

I also like this recipe because it’s not a heavy dish. The vegetables and chicken breasts are light and not cooked in a lot of oil. Sometimes I enjoy the fajitas as is for a low-carb meal or you can also make a fajita bowl with rice.

This is a great weeknight dinner, but it’s also fun to make for guests. You can cook a big batch of oven chicken fajitas and make a fajita bar with all of the toppings for people to choose from. 

Ingredients in Oven Fajitas

  • Cooking spray – so your chicken doesn’t stick to the pan
  • Sliced bell peppers – We love using red bell peppers and yellow bell peppers but you could also add a green pepper.
  • Sliced yellow onion – Slice them about the same thickness as the peppers.
  • Olive oil
  • Chicken – Boneless, skinless chicken breasts are the best to use for this recipe.
  • Fajita seasoning – or use taco seasoning if that’s what you have on hand. If you have a great homemade fajita seasoning you can use that, but we buy the easy packets (and sometimes add a bit more chili powder because we like them spicy).
  • Flour tortillas – or use corn tortillas if you prefer.
  • Cheese – We love using shredded Monterey jack cheese, but cheddar cheese or a Mexican blend cheese works great too!
  • Toppings: Salsa, sliced avocados, and sour cream, lime

How to Make Sheet Pan Fajitas

  • Position an oven rack in the top of the oven and turn on the broiler to preheat.
  • While the oven preheats, line a large rimmed baking sheet with foil and coat it with nonstick cooking spray.
  • Spread the sliced peppers and onions in an even layer on the prepared pan. Drizzle a tablespoon of oil over the top.
  • Place the pan under the broiler and cook the peppers and onions until they are softened for about seven to ten minutes.
  • While the vegetables cook, prep the chicken. First, slice the chicken into thin strips and then place them in a large bowl. 
  • Sprinkle the fajita seasoning over the top, and then add the rest of the olive oil. Toss the chicken with the oil and seasoning, so it’s evenly coated.
  • When the vegetables are softened, take the pan out of the oven. Place the chicken strips in an even layer on top of the peppers and onions. 
  • Put the pan back under the broil for five to seven minutes or until the chicken cooked through – the internal temperature should be 165°F.
  • Place the chicken fajitas on warm tortillas and add the cheese, avocado, and sour cream.

Recipe Swap

Make steak fajitas with flank steak or skirt steak. Thinly slice the beef and cook it on top of the onions and peppers until it’s done to your liking.

Or, you can make shrimp fajitas. Use peeled and deveined shrimp, toss them in the seasoning, and cook them with the vegetables.

Topping Ideas

  • Serve these on flour or corn tortillas, or even make a fajita salad.
  • Top with cheese, avocado slices, salsa, sour cream, or even guacamole.
  • We love a squeeze of fresh lime juice on top too!

FAQs

How do you keep chicken fajitas from drying out?

Make sure not to overcook the chicken. Only cook it until it reaches 165°F otherwise it’ll be over cooked and dry.

What pan is best for fajitas?

Use a thick rimmed baking sheet – like a cookie sheet – for this recipe.

What temperature do you cook fajitas at?

Broil these on high temperature.

How do you make veggies not soggy for fajitas?

Broiling these makes them nice and crispy – and don’t overcook the vegetables. The key is making sure the chicken slices aren’t too large – then they’ll cook at the same rate as the peppers.

Put 1 tablespoon of oil drizzled on the onions and peppers. Cook for 7-10 minutes or until peppers and onions are soft but not burned.

Recipe Notes

Mel’s tips:
  • If you don’t have fajita seasoning you can use taco seasoning.
  • You can substitute chicken with steak or shrimp.
  • You don’t have to use the broiler. You can bake them instead. We used the broiler to get a little char.
  • Cilantro, Jalapeno peppers and lime juice also go well with your fajitas
