Mexican Beef Corn Casserole

This Mexican casserole brings together seasoned ground beef, black beans, corn tortillas, and layers of melted colby jack cheese to create a satisfying dish with rich Tex-Mex flavors. It’s perfect for busy weeknights or feeding a hungry crowd, and it tastes even better the next day when the flavors have melded.

I first made this casserole for a family gathering, and it was such a hit that it instantly became a requested dish for taco night. The leftovers are so good that sometimes I make double and eat it all week long.

Ingredients

• Lean ground beef: provides protein and a rich savory base for the dish choose 90 percent lean for less grease
• Yellow onion: adds sweetness and aroma look for firm unblemished onions with shiny skins
• Water: used to help dissolve the taco seasoning and create a saucy filling
• Taco seasoning packets: key for authentic Tex-Mex flavor I recommend mild if serving to kids or go spicy if you like a kick
• Diced tomatoes and green chilies: their zest and slight heat elevate the dish draining them prevents soggy tortillas
• Black beans: add earthy protein and fiber rinse well to remove excess sodium from the can
• Mild jarred salsa: brings moisture and an extra dose of flavor to the casserole layers
• Yellow corn tortillas: soft corn tortillas hold the casserole shape and add authentic texture fresh ones work best but day old can work too
• Colby jack cheddar cheese: melts beautifully to bind the layers and add creamy richness
• Roma tomatoes and green onions: fresh garnishes that brighten each bite
• Sour cream: optional but adds a cool tangy contrast to the warm casserole

Step by Step Instructions

Preheat the oven:

Set your oven to 350 degrees Fahrenheit to ensure it reaches the perfect temperature while you prepare the filling and layering ingredients

Brown the beef and sauté the onions:

In a large saucepan over medium high heat cook the ground beef and chopped yellow onion together stirring often until the beef loses its pink color and the onions are translucent and soft This usually takes about five to six minutes Drain any excess fat to avoid a greasy casserole

Combine seasonings and simmer:

Add one cup of water and the taco seasoning packets to the browned beef mixture Stir continuously for three to four minutes allowing the seasoning to dissolve and coat the meat evenly This helps build a concentrated flavor base for the casserole

Incorporate tomatoes beans and salsa:

Stir in the drained diced tomatoes with green chilies rinsed black beans and half of the jarred salsa Heat just until the mixture begins to bubble gently then remove from heat This ensures everything is hot and well combined without overcooking

Prepare the baking dish and layer:

Spread the remaining half of the jarred salsa evenly on the bottom of a nine by thirteen inch baking dish Arrange six corn tortillas over the salsa layer gently overlapping as needed to cover the surface

Add filling and cheese:

Spread one third of the beef mixture over the tortillas then sprinkle two cups of shredded colby jack cheese on top covering the layer entirely Repeat these three layers tortillas beef mixture and cheese twice more to build a sturdy casserole

Bake covered then uncover:

Cover the casserole loosely with aluminum foil and bake in the preheated oven for thirty five minutes For the last five minutes remove the foil to allow the cheese on top to brown and bubble nicely

Rest before serving:

After baking let the casserole rest for ten to fifteen minutes This resting time is crucial as it lets the tortillas absorb the sauce and helps the casserole set for clean easy slices Cut into twelve equal servings for the perfect portion size

Garnish and serve:

Sprinkle the casserole with diced roma tomatoes and thinly sliced green onions then add a dollop of sour cream if desired Serve while warm to enjoy the melty cheese and savory layers fully

Storage Tips

Once cooled store leftovers in an airtight container in the refrigerator for up to four days Reheat individual portions in the microwave or cover loosely with foil and warm through in a 350 degree oven You can also freeze the casserole in portions wrapped tightly with plastic wrap and foil for up to three months Thaw overnight in the fridge before reheating to preserve texture

Ingredient Substitutions

Ground turkey or chicken can replace beef for a lighter option though the beef provides more richness You can swap black beans for pinto or kidney beans based on your preference or pantry stocking Use flour tortillas if you prefer a softer more pliable layer but expect a different texture Cheese varieties like Monterey Jack or a Mexican blend work well if you don’t have colby jack

Serving Suggestions

Serve this casserole alongside a fresh green salad with lime vinaigrette or simple guacamole for extra zest Add crunchy tortilla chips on the side or sprinkle some sliced avocado on top for creaminess A side of Mexican rice or refried beans turns this into a full Tex-Mex feast
