Ingredients You’ll Need
This recipe uses simple, easy-to-find ingredients to create a truly spectacular dish. Here’s what you’ll need to grab:
- Ground Beef: I recommend using 85/15 or 90/10 lean ground beef for the best flavor without too much grease.
- Onion & Garlic: These create the aromatic base that builds the savory flavor.
- Taco Seasoning: Use your favorite store-bought packet or a homemade blend.
- Red Enchilada Sauce: This adds a rich, tangy, and slightly spicy element that brings everything together.
- Black Beans & Corn: These add texture, fiber, and classic Tex-Mex flavor. Make sure to rinse the beans and drain the corn.
- Tortilla Chips: The heart of the casserole! They create delicious layers. Choose a sturdy chip that won’t get too soggy.
- Mexican Cheese Blend: A pre-shredded blend of Monterey Jack, Cheddar, and Colby melts beautifully.
- Optional Toppings: Sour cream, diced avocado, fresh cilantro, and jalapeños are all fantastic additions.
How to Make The Best Mexican Ground Beef Casserole
Making this incredible casserole is as easy as layering and baking. Just follow these simple steps for a perfect result every time.
Step 1: Brown the Beef and Aromatics
Start by preheating your oven to 375°F (190°C). In a large skillet over medium-high heat, cook the ground beef and diced onion until the beef is browned and the onion is soft. Drain off any excess grease. Stir in the minced garlic and cook for another minute until fragrant.
Step 2: Create the Savory Filling
Stir the taco seasoning, half of the enchilada sauce, the rinsed black beans, and the drained corn into the skillet with the ground beef. Let it simmer for 3-5 minutes, allowing the flavors to meld together beautifully.
Step 3: Layer the Casserole
Now for the fun part! Spread a thin layer of the remaining enchilada sauce in the bottom of a 9×13 inch baking dish. Arrange a single layer of tortilla chips to cover the bottom. Top the chips with half of the ground beef mixture, followed by one-third of the shredded cheese. Repeat the layers one more time: tortilla chips, the rest of the beef mixture, and another third of the cheese.
Step 4: Bake to Golden Perfection
Finish with a final layer of tortilla chips and the remaining cheese. Bake for 20-25 minutes, or until the casserole is hot and bubbly and the cheese is melted and golden. Let it rest for a few minutes before serving to allow it to set.
Tips for the Perfect Casserole
Want to guarantee a flawless Mexican Ground Beef Casserole every time? Here are a few of my top tips.
- Don’t Skip Draining: Draining the grease from the beef is crucial to prevent a soggy casserole.
- Use Sturdy Chips: Thicker, restaurant-style tortilla chips hold up better to the sauce and fillings.
- Shred Your Own Cheese: For the ultimate melt, shred a block of cheese yourself. Pre-shredded cheese has anti-caking agents that can affect how it melts. If you’re looking for other cheesy dinner ideas, this Keto Pizza Casserole is always a hit.
Fun Variations to Try

- Different Meat: Swap the ground beef for ground turkey, chicken, or even chorizo for a different flavor profile.
- Add More Veggies: Mix in diced bell peppers, zucchini, or spinach with the ground beef mixture.
- Spice It Up: Add a diced jalapeño or a pinch of cayenne pepper to the beef mixture for extra heat.
- Make it Creamy: Stir in 4 ounces of cream cheese with the ground beef mixture for a richer, creamier texture. For another creamy appetizer idea, try these Jalapeño Popper Twists.
