Chicken Fajita Casserole is the ultimate weeknight dinner hero—a bold, zesty, cheesy one-pan dish that captures all the sizzling flavors of classic chicken fajitas in a creamy, satisfying baked casserole. This recipe is a celebration of Tex-Mex comfort, transforming humble chicken breast, bell peppers, onions, and rice into a vibrant, flavor-packed meal that comes together with minimal fuss. The magic begins with a zesty marinade of olive oil, lime juice, honey, and a robust blend of garlic powder, chili powder, cumin, and smoked paprika, which infuses the chicken with that unmistakable fajita flavor. After a quick sear to lock in those juices, the chicken is set aside while the peppers and onions are sautéed until lightly charred, then the rice is toasted to perfection in the same skillet.
The brilliance of this casserole lies in its clever one-pan, skillet-to-oven method. Everything comes together in a single ovenproof skillet—no extra baking dishes to wash. The instant rice cooks right in the casserole, absorbing the savory combination of chicken broth, cream of chicken soup, and fire-roasted tomatoes, along with all the fajita spices and pan drippings. The result is a creamy, slightly smoky, beautifully textured casserole that’s topped with a generous blanket of melted cheddar cheese. Serve it hot with a dollop of sour cream and a spoonful of salsa for a complete, crowd-pleasing meal. Whether you’re feeding your family on a busy Tuesday or bringing a dish to a potluck, this Chicken Fajita Casserole is guaranteed to disappear fast.

Ingredients:
For the Chicken Marinade:*
2 tablespoons olive oil
1½ teaspoons garlic powder
1½ teaspoons chili powder
1 teaspoon ground cumin
1 teaspoon smoked paprika
2 tablespoons fresh lime juice
1 tablespoon honey
For the Casserole:*
1¼ lbs boneless, skinless chicken breast, cut into bite-sized pieces
1 tablespoon vegetable oil (plus more as needed)
1 small yellow onion, chopped
1 red bell pepper, chopped
1 orange or yellow bell pepper, chopped
2 cups instant rice (such as Minute Rice)
1½ cups low-sodium chicken broth
1 (10-ounce) can condensed cream of chicken soup
1 (15-ounce) can fire-roasted diced tomatoes (undrained)
½ teaspoon kosher salt
½ teaspoon freshly ground black pepper
1½ cups shredded cheddar cheese
For Serving (Optional):*
Salsa
Sour cream
Fresh cilantro, chopped
Instructions:
Step 1: Make the Marinade*
In a large bowl, whisk together the olive oil, garlic powder, chili powder, ground cumin, smoked paprika, lime juice, and honey until well combined.
Step 2: Marinate the Chicken*
Add the bite-sized chicken pieces to the bowl with the marinade. Toss to coat evenly. Cover and refrigerate for 30-60 minutes (or up to 2 hours).
Step 3: Preheat Oven*
Preheat your oven to 350°F (175°C).
Step 4: Sear the Chicken*
Heat 1½ tablespoons of vegetable oil in a large, ovenproof skillet (such as cast iron or stainless steel) over medium-high heat. Working in batches to avoid overcrowding, add the marinated chicken pieces and cook until browned on both sides, about 5-6 minutes total. Remove the chicken to a plate and set aside.
Step 5: Sauté the Vegetables*
Add a little more oil to the skillet if needed. Add the chopped onion and bell peppers. Cook over medium-high heat, stirring occasionally, until the vegetables are lightly browned on the edges, about 3-4 minutes.
Step 6: Toast the Rice*
Add the instant rice to the skillet with the vegetables. Cook for 2-3 minutes, stirring constantly, until the rice is lightly toasted and fragrant.
Step 7: Add Liquids and Chicken*
Stir in the chicken broth, cream of chicken soup, fire-roasted tomatoes (with their juices), salt, and black pepper. Add the seared chicken back to the skillet. Stir until everything is well combined.
Step 8: Bake Covered*
Cover the skillet with a tight-fitting lid or aluminum foil. Bake for 30 minutes, until the rice is tender and has absorbed most of the liquid.
Step 9: Add Cheese and Finish*
Remove the skillet from the oven. Sprinkle the shredded cheddar cheese evenly over the top. Return to the oven (uncovered) and bake for an additional 5-10 minutes, until the cheese is melted and bubbly.
Step 10: Serve*
Let the casserole rest for 5 minutes before serving. Serve hot with salsa, sour cream, and fresh cilantro if desired.
Tips:
- Don’t Skip the Marinade: Even 30 minutes of marinating makes a big difference in flavor.
- Work in Batches: Overcrowding the pan when searing the chicken will cause it to steam instead of brown.
- Use Fire-Roasted Tomatoes: They add a subtle smoky flavor that elevates the entire dish.
- Instant Rice is Key: Regular rice requires more liquid and a longer cooking time. Instant rice is essential here.
- Customize the Heat: Add a diced jalapeño with the peppers, or serve with hot salsa for extra spice.
Storage Options:
- Refrigerator: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: Reheat individual portions in the microwave, or cover the baking dish with foil and reheat in a 325°F (165°C) oven until warmed through.
- Freezer: This casserole freezes well for up to 2 months. Cool completely, wrap tightly in plastic wrap and foil, and freeze. Thaw overnight in the refrigerator before reheating.
- Make-Ahead: Assemble the casserole (through Step 7), cover, and refrigerate for up to 24 hours. Bake as directed, adding 10-15 minutes to the covered bake time.
Chicken Fajita Casserole is the perfect solution when you’re craving bold Tex-Mex flavors but want the ease of a one-pan baked dinner. Creamy, cheesy, and packed with smoky, zesty goodness, it’s a weeknight winner. Enjoy!
