This Chicken Fajita Casserole is a cozy, all-in-one dinner that bakes up with tender chicken, fluffy rice, and plenty of bold Tex-Mex flavor. It’s hearty, cheesy, and the kind of no-fuss meal that makes busy nights feel a whole lot easier, especially if you already love recipes like my easy chicken fajitas.
Holly’s Recipe Highlights: Chicken Fajita Casserole
Flavor: Boldly seasoned Tex-Mex flavor with zesty salsa, creamy melted cheese, and a hint of sweetness from the peppers and onions.
Why Make It: I love making this because everything bakes in one dish, prep is so simple, and cleanup is just as easy.
Serving Suggestions: Serve with a dollop of sour cream, homemade guacamole, fresh cilantro, easy pico de gallo, or a sprinkle of green onions for extra flavor and freshness.
Total Time: 70 Mins Servings: 6 Cooking Method: Baked
Ingredient Notes
- Rice: Long-grain white rice is the way to go here since it bakes up fluffy and tender, while brown rice or instant rice just won’t cook quite the same in this casserole.
- Salsa: Salsa is what seasons the casserole, so use one you already love. Use medium or mild salsa for a family-friendly version, or hot salsa for more kick. For a heartier casserole, choose a chunky salsa.
- Chicken: Chicken tenderloins cook evenly as they are, but if using chicken breasts, cut them into ¾-inch strips so they cook through in the same amount of time.
- Seasoning: Fajita seasoning can be store-bought for the fastest option, or make your own homemade fajita seasoning to control the salt level and adjust the heat to your liking.
- Onions & Peppers: Frozen bell peppers and onions are a great shortcut that keeps prep simple. Freshly sliced peppers and onions can also be used, but the frozen blend layers in easily and releases flavor as it bakes.
- Cheese: Mexican cheese blend melts well and gives the casserole a creamy, bubbly finish. Cheddar, Monterey Jack, or pepper jack all work well too.
- Variations:
- Black beans or corn can be added for a heartier Tex-Mex feel.
- Homemade salsa verde adds a brighter, tangier flavor, and jalapeño slices on top are a great way to turn up the heat.
