Easy Oven-Baked Beef Enchilada Casserole

Step-by-Step Guide: How to Layer and Bake

The beauty of this casserole is how quickly it comes together once your meat base is cooked. Grab a standard 9x13-inch baking dish, preheat your oven to 375°F (190°C), and follow these simple steps:

1. Brown and Season the Beef

In a large skillet over medium-high heat, add the ground beef and diced onion. Cook, breaking the meat apart with a wooden spoon, until the beef is fully browned and the onions are soft and translucent. Carefully drain off any excess grease. Stir in your taco seasoning and a splash of water, letting it simmer for 2 to 3 minutes until the liquid is absorbed and the meat is deeply fragrant.

2. Lay the Foundation

Pour about 1/2 cup of the red enchilada sauce directly into the bottom of your 9x13-inch baking dish and tilt it to coat the surface. This creates a non-stick barrier and ensures your bottom layer of tortillas absorbs maximum flavor. Arrange a layer of corn tortillas across the bottom, overlapping them slightly to completely cover the sauce. (Pro tip: Cutting a few tortillas in half helps them fit snugly against the straight edges of the dish).

3. Build the Enchilada Layers

Now, it is time to stack:

• Spread half of your seasoned ground beef mixture evenly over the tortillas.

• Drizzle about 1/3 of the remaining enchilada sauce over the meat.

• Sprinkle 1/3 of your shredded cheese generously over the sauce.

• Repeat the process: Add another layer of corn tortillas, the remaining ground beef, another 1/3 of the sauce, and another 1/3 of the cheese.

4. The Grand Finale Top Layer

Finish the casserole by placing a final layer of corn tortillas on top. Pour the remaining enchilada sauce over the top, using a spatula to ensure every inch of the tortillas is covered so they do not dry out in the oven. Blanketing the whole dish with the final third of your shredded cheese.

5. Bake Until Bubbly

Cover the baking dish loosely with aluminum foil (make sure it doesn't touch the cheese directly so it doesn't stick!) and bake at 375°F for 20 minutes.

Carefully remove the foil and bake for an additional 10 minutes, or until the cheese is completely melted, golden-brown at the edges, and bubbling dynamically throughout the dish.

Pro-Tips for Serving and Customization

As tempting as it is to dive right in the second the timer goes off, let the casserole rest on the counter for 5 to 10 minutes before slicing. This brief cooling period allows the layers to set, ensuring you get neat, beautiful squares instead of a loose scramble when you scoop it out.

To take your beef enchilada casserole to the next level, set up a colorful topping bar so everyone can customize their plate. It pairs wonderfully with:

• A dollop of cool sour cream or Mexican crema.

• Diced fresh tomatoes or a scoop of chunky pico de gallo.

• Freshly sliced jalapeños for an extra kick of heat.

• A generous sprinkle of chopped fresh cilantro and a squeeze of fresh lime juice.

Whether you are feeding a hungry family on a Tuesday night or hosting a casual weekend gathering, this oven-baked masterpiece delivers all the nostalgic comfort of a traditional Mexican restaurant favorite with a fraction of the kitchen stress
