4. Step-by-Step Instructions

Preparing the Ingredients

Preheat your oven to 375°F (190°C). Slice the chicken, onion, and bell peppers into even pieces to ensure consistent cooking. Mince the garlic and measure out all spices. Shred the cheese if not pre-shredded. Having everything prepped and ready will streamline the cooking process. For more prep tips, visit our guide on meal prep recipes here.

Cooking the Chicken and Veggies

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the chicken pieces and cook until lightly browned, about 5–7 minutes. Remove the chicken from the pan and set aside. In the same skillet, sauté the sliced onions and bell peppers until softened, about 5 minutes. Stir in minced garlic, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper. Return the chicken to the skillet and toss everything together to combine.

Assembling the Casserole

Grease a baking dish and spread cooked rice evenly across the bottom (if using). Layer the chicken and veggie mixture on top. Sprinkle half of the shredded cheese over the mixture to create a gooey middle layer. For assembly tips, browse our collection of one-pan meals here.

Baking the Casserole

Cover the dish with foil and bake for 20 minutes. Remove the foil, sprinkle the remaining cheese on top, and bake for an additional 10–15 minutes or until the cheese is bubbly and golden. Let the casserole rest for 5 minutes before serving to allow flavors to meld. For baking techniques, check out our resource on cheesy baked dishes here.
