Directions to follow
Follow these simple steps to create your casserole masterpiece:
- Preheat your oven to 375°F (190°C).
- In a large skillet, heat olive oil over medium heat. Add in the chopped onion and garlic, sautéing until soft and fragrant, about 3-4 minutes.
- Stir in the ground cumin, chili powder, salt, and pepper. Cook for another minute to toast the spices and release their flavor.
- In a large mixing bowl, combine the shredded chicken, cooked rice, black beans, corn, diced tomatoes with green chilies, the sautéed onion mixture, sour cream, and salsa. Mix everything well until fully incorporated.
- Spread half of the chicken mixture evenly in a greased 9×13-inch baking dish.
- Sprinkle half of the shredded cheddar and Monterey Jack cheeses over the mixture.
- Layer the remaining chicken mixture on top, followed by the remaining cheese.
- Cover with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
- Let the casserole rest for 5 minutes before serving, and garnish with fresh chopped cilantro.
How to plate and pair
Serving your Mexican Chicken Casserole is all about presentation. Scoop generous portions onto plates and top with additional cilantro for a pop of color. It pairs beautifully with a refreshing side salad or some warm, crusty bread. You can also offer toppings like avocado slices, jalapeños, or extra salsa on the side to let everyone customize their plate.
How to store & freeze
Storing leftovers? This casserole holds up wonderfully in the fridge for up to 3-4 days in an airtight container. For longer storage, consider freezing portions. It freezes well for up to 3 months. Just make sure to wrap it tightly to prevent freezer burn. To reheat, simply thaw overnight in the fridge and warm in the oven for baked perfection.
