This Chicken Fajita Bake (Dump and Bake Casserole) is a weeknight-friendly, one pan, minimal prep dinner packed with Tex-Mex flavor and cheesy goodness. It's an easy chicken fajita casserole made with chicken breast strips, black beans, corn, rice, and bell peppers all baked together under a melted pepper jack cheese topping.
Similar to our Easy Vegetarian Quesadillas or our Tex Mex Stuffed Peppers, it's perfect for busy nights or meal prep.
Chicken Fajita Bake is a simplified version of classic chicken fajitas, where everything cooks together in one dish instead of separately on the stovetop.
Traditional fajitas are grilled or sautéed, then served in tortillas, but this version layers seasoned chicken, rice, vegetables, and cheese for a cozy, all-in-one casserole that mimics the popular Chipotle bowl.

Chicken Fajita Bake Ingredients
We're using easy pantry staples with Tex-Mex flavor built right in. Here's what you'll need:
- Chicken Breasts: We slice them into strips for quicker, even baking and better seasoning coverage.
- Uncooked Long Grain White Rice: This absorbs the broth as it bakes, turning fluffy and tender.
- Chicken Broth: Adds savory flavor and helps the rice cook evenly.
- Black Beans and Corn: These add protein, fiber, and color. We use canned beans and frozen corn for ease. If you prefer homemade beans, try swapping in our Chipotle Pinto Beans.
- Chipotle Pepper in Adobo and Adobo Sauce: A little goes a long way. This gives depth and heat without overwhelming.
- Bell Peppers (Red, Yellow, Orange): Use a mix for color and sweetness.
- Yellow Onion: Adds mild flavor and softens nicely while baking.
- Pepper Jack Cheese: This adds the perfect kick and melts well over the top.
A full ingredient list with exact measurements can be found in the recipe card below.
Substitutions & Variations
- Chicken Breasts: Rotisserie chicken or pre-cooked chicken can be used if you add it in towards the end of baking.
- Black Beans: Pinto beans make a great substitution.
- Fajita Seasoning: Can be made homemade by mixing chili powder, cumin, garlic powder, onion powder, and paprika.
- Chipotle in Adobo: Use smoked paprika instead or skip for a no-spice version.
- Presentation: Serve in bowls with toppings like a burrito bowl.
How To Make a Chicken Fajita Casserole
STEP ONE: Prepare the Rice Base
In a greased 9x13 baking dish, stir together the uncooked white rice, chicken broth, drained black beans, and frozen corn. Spread into an even layer.
STEP TWO: Prepare the Chicken and Veggies
In a separate bowl, toss sliced chicken, bell peppers, and onion with olive oil, fajita seasoning, chopped chipotle, adobo sauce, salt, and pepper until everything's well coated.
STEP THREE: Assemble the Bake
Spoon the seasoned chicken and vegetables evenly over the rice base without stirring.
Sprinkle shredded pepper jack cheese across the top.
STEP FOUR: Bake and Finish
Cover tightly with foil and bake at 375°F for 40-45 minutes until the rice is cooked through and the liquid is absorbed.
Let rest 5-10 minutes, then sprinkle with dried oregano and garnish as desired.

Recipe FAQs
It's not recommended unless pre-cooked. Brown rice takes longer and may stay underdone. Try par-cooked brown rice if you want a healthier swap.
It's mildly spicy from the chipotle and pepper jack cheese, but you can tone it down by omitting the chipotle and using mild cheese.
We love chopped cilantro, a squeeze of lime, sliced avocado, and a dollop of sour cream. Tortilla chips on the side are great for scooping.
