To make fajita chicken bake I combined skinless boneless chicken breasts together with multi-colored bell peppers, canned green chiles, and pepper jack cheese in a cast iron pan.
I baked the chicken, veggies, and cheese for about 20 minutes or so, and the dinner was ready!
There are only 4 main ingredients (not including the spices and the olive oil), 30 minutes from start to finish, and only one pan to clean at the end!
Serve it however you like. I served this fajita chicken bake as is. You can also add some carbs to it if you like. This includes corn tortillas, black beans, and rice. Add your favorite toppings, such as sour cream, shredded cheese, Cotija cheese, diced avocado, chopped green onions, salsa, or guacamole.

Fajita chicken bake vs classic chicken fajitas - what's the difference?

Traditionally, chicken fajitas require a really hot griddle or a flaming hot cast iron pan to get a nice sear and that nice smoky flavor. I prefer my food baked anyway, and this is the only difference. In my recipe, chicken fajita ingredients are baked in the oven. It's easy, less messy, quicker, and no smoke in the house! Perfect for busy family weeknights.

Why you'll love this recipe

An unusual twist on classic fajitas. This easy meal turns regular chicken fajitas into something a bit different. Whole chicken breasts are cooked together with bell peppers, green chile peppers, and pepper jack cheese to create a super flavorful chicken bake that tastes just like regular chicken fajitas.
One-pan 30-minute recipe. It's an easy recipe that requires only one oven-safe skillet, such as a cast-iron skillet, and takes only 30 minutes. Because the chicken fajitas are baked vs seared on high flame, the house stays cleaner and doesn't get smoky.
Juicy and flavorful chicken breasts. Say goodbye to boring, dried-out chicken. I generously coated skinless boneless chicken breasts with classic fajita seasonings (paprika, chili powder, and cumin), then smothered them with lots of cheese. The chicken was baked in the oven until perfection!

Keto-friendly, low-carb, gluten-free dinner

You will be impressed with how much flavor is packed into this simple family-friendly weeknight dinner. It's a low-carb and keto-friendly meal that features protein (chicken), lots of veggies (bell peppers), and fat (pepper jack cheese).

The Ingredients

I love easy one-pan recipes that feature basic ingredients. Chicken Fajita Bake is one of those recipes. There are only 4 main ingredients (excluding spices and olive oil). Here they are:

Chicken breasts. I used 2 large skinless boneless chicken breasts. I sliced each one in half to create 4 smaller chicken breasts.
Bell peppers. I used 3 small bell peppers of different colors (red, yellow, and green) to add vibrancy to the dish.
Canned green chiles. I used the mild variety. If you like your food spicier, use medium or hot.
Pepper jack cheese. I purchased a block of pepper jack cheese and shredded it myself.

Homemade fajita seasoning

I used basic spices, such as chili powder, smoked paprika, ground cumin, salt, and pepper in this recipe. You can also add garlic powder and dried oregano.

Variations

Chicken. I used skinless boneless chicken breasts, you can also use skinless boneless chicken thighs or chicken tenderloins.
Veggies. Add some variety to classic chicken fajitas by using other veggies, such as mushrooms, asparagus, or broccoli.
Cheese. I used pepper jack cheese. You can also use Monterey jack cheese or white cheddar.

Toppings for baked fajita chicken

This recipe is a meal all on its own that doesn't need anything to be added. But, if you like, you can make it even better with your favorite toppings. Here are some ideas:

Chopped fresh cilantro
A dollop of sour cream or Greek yogurt
Fresh lime slices
Green onions or chives
Crumbled Cotija cheese
Salsa
Pico de Gallo
Guacamole

How to serve it

Serve it as is - a low-carb, keto-friendly, gluten-free dinner. This recipe is a complete meal in itself as it features lots of protein (chicken), veggies (bell peppers), and cheese (pepper jack).
Turn this recipe into regular chicken fajitas. All you have to do is divide up the cooked chicken into warmed tortillas and serve them with toppings, such as sour cream, sliced avocado, cheese, pico de Gallo, salsa, or guacamole.
Make a chicken fajita salad by tossing this chicken over some greens, such as lettuce, spinach, or arugula.
Add rice and black beans as side dishes to soak up all the flavorful juices!
