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.
Frozen or canned corn: Contributes sweetness and a bit of crunch.
Salsa: Brings a tangy and spicy element to the casserole.
Shredded cheddar cheese: Melts on top to create a gooey, delicious layer.
Taco seasoning: Infuses the beef with classic Mexican flavors.

Technique Tip for This Recipe
When browning the ground beef, make sure to break it up into small, even pieces using a wooden spoon or spatula. This ensures that the taco seasoning coats the meat evenly, enhancing the flavor throughout the casserole. Additionally, for a richer taste, consider sautéing some chopped onions and garlic with the beef before adding the seasoning. This extra step can add depth to the overall flavor profile of the dish.

How To Store / Freeze This Casserole
Allow the Mexican casserole to cool completely before storing. This prevents condensation from forming inside the container, which can make the dish soggy.
Transfer the cooled casserole to an airtight container. If you plan to store it in the same baking dish, cover it tightly with aluminum foil or plastic wrap.
Store the casserole in the refrigerator if you plan to eat it within 3-4 days. This keeps the ground beef and cheddar cheese fresh and safe to eat.
For longer storage, freeze the casserole. Wrap the entire dish in a layer of plastic wrap, followed by a layer of aluminum foil. This double wrapping helps prevent freezer burn and keeps the salsa and corn from losing their texture.
Label the container with the date and contents. This helps you keep track of how long the casserole has been stored and ensures you use it within a safe timeframe.
When ready to reheat, thaw the frozen casserole in the refrigerator overnight. This gradual thawing helps maintain the quality of the black beans and sour cream.
Preheat your oven to 350°F (175°C) for reheating. Remove any plastic wrap and cover the casserole with aluminum foil to prevent the cheese from over-browning.
Bake the thawed casserole for 20-25 minutes, or until heated through. If reheating from frozen, it may take up to 45 minutes. Remove the foil during the last 10 minutes to allow the cheddar cheese to become bubbly and golden.
Alternatively, individual portions can be reheated in the microwave. Place a serving on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, or until hot. Stir halfway through to ensure even heating.
How To Reheat Leftovers
