Can I use chicken thighs instead of breasts for this Cheesy Chicken Fajita Casserole Recipe?

Absolutely! Boneless skinless chicken thighs work great here. They’ll add extra juiciness and flavor but may require a few extra minutes of cooking time—just check the internal temperature to be safe.

What’s the best way to make this recipe lower in calories?

You can reduce calories by skipping the shredded cheese and instead topping with a mixture of parmesan and panko breadcrumbs lightly sprayed with oil before baking. Also, serving with cauliflower rice instead of pasta or traditional rice cuts carbs and calories.

Can I prepare this casserole ahead of time?

Yes! You can assemble the casserole the night before, cover it tightly, and refrigerate it. When you’re ready, just bake as directed, adding a few extra minutes if it comes straight from the fridge.

Instructions

Preheat Oven: Preheat your oven to 400°F (200°C) ensuring it's hot enough to cook the casserole evenly.
Season Chicken: In a baking dish, place the chicken breasts and evenly coat them with the fajita seasoning and vegetable oil, using your hands to ensure thorough coverage.
Add Vegetables and Cheese: Layer the sliced bell peppers and onions over the seasoned chicken. Sprinkle a little extra fajita seasoning if desired, then top everything with the shredded cheese evenly.
Bake: Place the uncovered baking dish in the oven and bake for 30 minutes until the chicken is cooked through and the cheese is melted and bubbly.
Garnish and Serve: Remove from oven and garnish with fresh chopped cilantro. Serve immediately while hot.

Notes

Check chicken doneness with a meat thermometer; the internal temperature should reach 165°F (74°C) to be safe for consumption.
Any type of melting cheese works well for this recipe depending on your preference.
To reduce calories, omit the cheese, top with parmesan mixed with panko breadcrumbs, spray with oil, and bake as usual.
For quicker cooking, cube the chicken into smaller pieces and reduce baking time accordingly.
Add cooked pasta (al dente) to the casserole for a heartier meal variation.
Serve the casserole alongside garlic butter pasta, plain pasta, Mexican rice, or cauliflower rice for a low-carb option.
Reheat leftovers in the oven at 350°F (175°C) for 15-20 minutes or use the microwave for convenience.
