This Mexican casserole is a delicious and hearty dish that combines the rich flavors of ground beef, black beans, corn, and salsa. Topped with melted cheese and baked to perfection, it's a crowd-pleaser that's perfect for any weeknight dinner or gathering.
If you don't usually stock black beans or taco seasoning in your pantry, you might need to pick these up at the supermarket. Black beans are typically found in the canned goods aisle, while taco seasoning can be found in the spice or international foods section. Ensure you also have salsa and shredded cheese on hand.

Ingredients For Mexican Casserole Recipe
Ground beef: Provides a rich and savory base for the casserole.
Black beans: Adds protein and a creamy texture to the dish.
Corn: Brings a sweet crunch to the casserole.
Salsa: Infuses the dish with a tangy and spicy flavor.
Cheddar or Mexican blend shredded cheese: Melts on top to create a gooey, delicious layer.
Taco seasoning: Adds a burst of Mexican-inspired spices.
Cooked rice: Provides a hearty and filling base for the casserole.
Technique Tip for This Recipe
When browning the ground beef, make sure to break it up into small, even pieces to ensure it cooks evenly. This will help the taco seasoning distribute more uniformly throughout the meat. Additionally, for a richer flavor, consider sautéing some finely chopped onions and garlic with the beef before adding the seasoning. This extra step can add depth to the overall taste of the casserole.

How To Store or Freeze Your Casserole
Allow the Mexican casserole to cool completely before storing. This prevents condensation from forming, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container. Refrigerate for up to 3-4 days. This keeps the ground beef and cheese fresh and flavorful.
If you plan to freeze the casserole, portion it into individual servings. This makes reheating easier and more convenient.
Wrap each portion tightly with plastic wrap, then place them in a freezer-safe container or heavy-duty freezer bags. Label with the date to keep track of freshness.
For best results, consume the frozen casserole within 2-3 months. This ensures the black beans, corn, and salsa maintain their texture and taste.
When ready to reheat, thaw the casserole in the refrigerator overnight. This gradual thawing helps retain the dish's original quality.
Reheat in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through. Cover with foil to prevent the cheese from over-browning.
Alternatively, you can reheat individual portions in the microwave. Place the portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, stirring halfway through.
For a crispy topping, you can broil the casserole for the last 2-3 minutes of reheating. Keep a close eye to avoid burning the cheese.
Enjoy your reheated Mexican casserole with fresh toppings like avocado, sour cream, or chopped cilantro for an added burst of flavor.
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover Mexican casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Heat for about 20-25 minutes, or until the cheese is melted and the casserole is heated through. For a crispy top, remove the foil during the last 5 minutes of heating.
Microwave Method: Transfer a portion of the casserole to a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Check the temperature and heat in additional 30-second increments if necessary.
Stovetop Method: Place the leftover casserole in a non-stick skillet over medium heat. Add a splash of water or broth to prevent sticking and to keep it moist. Stir occasionally and heat until warmed through, about 8-10 minutes.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the casserole in an air fryer-safe dish or line the basket with parchment paper. Heat for 5-7 minutes, checking halfway through to ensure it doesn't overcook. This method will give you a slightly crispy top.
Slow Cooker Method: Transfer the casserole to your slow cooker. Set it on low and heat for 1-2 hours, or until the casserole is heated through. This method is great for maintaining moisture and flavor.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the casserole in a toaster oven-safe dish. Cover with aluminum foil and heat for 15-20 minutes, or until the cheese is melted and the casserole is hot. Remove the foil for the last 5 minutes if you prefer a crispy top.
