How to Make The Best Mexican Casserole Recipe

Step 1: Brown the Beef and Sauté the Onion

Start by heating a large skillet over medium-high heat. Add the ground beef and let it sear, breaking it up as it cooks, until it’s beautifully browned and crumbly. Toss in your chopped onion and let it soften until fragrant—this foundation gives The Best Mexican Casserole Recipe its signature savory backbone.

Step 2: Season and Add Vegetables

Sprinkle in the taco seasoning, stirring well to ensure every piece of beef is coated in those bold, zesty spices. Next, pour in the drained black beans and corn, followed by the entire can of diced tomatoes with green chilies (including the juices). Mix it all together and let the mixture simmer for about five minutes so the flavors marry nicely.

Step 3: Assemble the Casserole

Lightly grease a baking dish, then begin with a layer of tortillas on the bottom. Spoon over a third of the beef mixture, followed by a generous handful of that shredded cheese. Repeat the layers—tortilla, beef mixture, cheese—two more times. This triple layering ensures every forkful is packed with maximum flavor and ooey-gooey goodness.

Step 4: Bake to Perfection

Slide the casserole into a preheated oven at 350°F. Bake uncovered for about 25 to 30 minutes, or until the cheese is bubbling and golden on top. Your kitchen will fill with the most irresistible aroma, making it hard to wait!

Step 5: Finish and Serve

After pulling it from the oven, let the casserole cool for just a few minutes—this makes it easier to slice and serve. Scatter fresh cilantro on top for an outrageously fresh, herby kick. Now, dig in and enjoy that first glorious bite of The Best Mexican Casserole Recipe!

How to Serve The Best Mexican Casserole Recipe

Garnishes

Top off each serving with a flourish of chopped cilantro, a dollop of creamy sour cream, and a few crisp, colorful slices of radish. If you love a little heat, pass around some sliced jalapeños or a few dashes of your favorite hot sauce to customize each plate.

Side Dishes

For a full fiesta, serve The Best Mexican Casserole Recipe alongside fluffy Spanish rice, a cool avocado salad, or simply some crunchy tortilla chips for scooping up every last morsel. Even a classic side of refried beans pairs beautifully, making dinner extra hearty and satisfying.

Creative Ways to Present

If you’re feeding a crowd, try assembling the casserole in individual ramekins—everyone gets their own cute mini portion. Or, transform leftovers into deliciously loaded burritos or bowls, topped with fresh salsa and extra cheese for a fun twist the next day.

Make Ahead and Storage

Storing Leftovers

After enjoying The Best Mexican Casserole Recipe, store any leftovers in an airtight container in the fridge for up to four days. It holds up wonderfully, making quick lunches or dinners a breeze.

Freezing

This casserole is freezer-friendly! Simply wrap cooled slices or the whole casserole tightly in plastic wrap and foil, then freeze for up to three months. For best results, let it thaw in the refrigerator overnight before reheating.

Reheating

For single portions, the microwave works perfectly—just be sure to cover the dish and heat in short bursts until warmed through. For larger portions, reheat in the oven at 350°F until piping hot and the cheese is melty once more. A quick sprinkle of fresh cheese before baking brings back that just-made magic!
