Step‑by‑Step Instructions for Mouthwatering Mexican Casserole

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C) to ensure it’s hot and ready for your Mouthwatering Mexican Casserole. This step is crucial as it allows the casserole to cook evenly and develop that beautiful, bubbly cheese topping we all love.

Step 2: Sauté the Ground Beef
In a large skillet, heat a drizzle of vegetable oil over medium-high heat. Add the lean ground beef and cook for about 8 minutes, stirring occasionally, until it’s browned and no longer pink. The meat should have a rich color, indicating it’s perfectly cooked.

Step 3: Add Aromatics
Toss in the diced medium onion and freshly minced garlic to the skillet with the browned beef. Sauté these aromatic ingredients for about 5 minutes, until the onion becomes translucent and fragrant. This step enhances the flavor base of your Mouthwatering Mexican Casserole beautifully.

Step 4: Mix in the Seasonings
Sprinkle the taco seasoning mix over the beef and aromatics, stirring to combine well. Then, blend in the black beans, corn kernels, diced tomatoes with green chilis, and salsa. Let this mixture simmer on low for about 5 minutes until it’s heated through and flavors meld together, creating a rich and savory filling.

Step 5: Prepare the Baking Dish
While the beef mixture simmers, grease a 9×13-inch baking dish with a bit of oil or cooking spray to prevent sticking. Lay half of the corn tortilla quarters evenly across the bottom, creating a sturdy base for your Mouthwatering Mexican Casserole.

Step 6: Layer with Meat Mixture
Spread half of the beef mixture over the tortilla layer in the baking dish. This will create a hearty interior, full of flavor. Follow that up by sprinkling 1 cup of shredded cheddar cheese over the meat for that gooey goodness we all crave.

Step 7: Build Additional Layers
Add the remaining tortilla quarters on top of the first layer. Next, evenly distribute the rest of the beef mixture over these tortillas, ensuring every bite is packed with flavor. Scoop dollops of sour cream across the top for extra creaminess that ties this dish together.

Step 8: Final Cheese and Toppings
Finish your casserole by generously scattering the remaining shredded cheddar cheese over the entire surface, followed by sliced black olives and chopped green onions for a pop of color and added flavor. This final layer will create a golden, bubbly crust as it bakes.

Step 9: Bake Your Casserole
Cover the baking dish with aluminum foil to prevent excessive browning and place it in the preheated oven. Bake for 25 minutes, then carefully remove the foil and continue baking for another 10 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and slightly golden brown.

Step 10: Cool and Serve
Once baked, remove the Mouthwatering Mexican Casserole from the oven and let it cool for about 10 minutes to set. This waiting time allows the layers to meld beautifully. Before serving, garnish with additional chopped green onions for a fresh touch.
