Instructions

1. Preheat oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.

2. In a large skillet, heat olive oil over medium heat. Add chicken strips and cook until lightly browned, about 5 minutes.

3. Add bell peppers and onions. Sauté for 5–6 minutes until slightly softened.

4. Stir in chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Mix well.

5. Transfer mixture to the prepared baking dish. Sprinkle cheddar and Monterey Jack cheese evenly on top.

6. Bake uncovered for 15–20 minutes, until cheese is melted and bubbly.

7. Top with sour cream and chopped cilantro before serving. Serve with rice, tortillas, or cauliflower rice for a complete meal.

Notes

Make it spicier by adding jalapeños or chipotle powder.

Use rotisserie chicken to save time — mix with sautéed veggies and bake with cheese.

This casserole reheats beautifully and is perfect for meal prep.

Garnish with avocado or a squeeze of lime for fresh flavor.
