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 375ยฐF 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.

Leftover chicken fajita casserole will keep for 3 to 4 days in the fridge. Freeze portions in airtight containers for up to 2 months. Reheat in the microwave or cover and warm in a 350ยฐF oven until hot.
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.

Notes
- Keep the foil sealed tightly during baking so steam cooks the rice properly.
- Slice chicken into even strips so everything cooks at the same rate.
- Layer the chicken on top instead of mixing it in so the rice doesn't turn mushy.
- Let the casserole rest 5-10 minutes so the texture firms up before serving.
