Mexican Casserole Recipe With Ground Beef: Layered Tex-Mex Comfort in One Dish

This layered casserole delivers Tex-Mex comfort in a single baking dish, perfect for busy weeknights. I developed this recipe after years of testing different combinations to achieve the ideal balance of flavors and textures.

The ground beef forms a savory base, while tortillas add structure and corn chips provide a satisfying crunch. Cheese melts into every layer, creating that irresistible gooey texture we all crave in a casserole.

What emerges from the oven is a bubbling, golden dish with perfectly balanced seasonings. Each bite offers the familiar tastes of tacos in a hearty, fork-friendly format that satisfies the whole family.

Serve this straight from the oven with your favorite toppings. The leftovers reheat beautifully for lunch the next day.

Ingredients for Mexican Casserole Recipe with Ground Beef

Ground beef, tortillas, cheese, and chips come together for this layered Tex-Mex dream in one dish.

The ground beef is the foundation here. 80/20 lean-to-fat ratio gives you the best flavor and moisture—Costco or Sam’s Club have great bulk options. For the tortillas, Mission brand holds up well to baking. I grab their flour tortillas from the refrigerated section—they stay soft longer. The cheeses? Sargento or Tillamook shred their own blocks, so no anti-caking agents to mess with the melt.

No taco seasoning? Mix 1 tbsp chili powder, 1 tsp cumin, 1 tsp paprika, 0.5 tsp garlic powder. Black beans can be pinto beans (same texture). Out of bell pepper? Zucchini or mushrooms work surprisingly well. The corn chips? Fritos or generic store brand both crush up the same. If you’re skipping the sour cream topping, avocado slices add a nice creamy contrast.

Assemble and bake right away, or prep the layers up to 24 hours ahead (keep covered in the fridge). Leftovers stay fresh for 4-5 days—the flavors actually deepen after a day. Freeze portions for up to 3 months if you’re making a double batch (and you should).

Step-by-Step Instructions for Mexican Casserole With Ground Beef

Here’s the method that turns simple layers into a bubbling, cheesy masterpiece your family will request weekly.

Step 1: Brown and Season the Ground Beef

Heat the 1 tbsp olive oil in a large skillet over medium-high heat. Add the 1.5 lb ground beef and cook, breaking it up with a wooden spoon, until no longer pink—about 5-7 minutes.

Once browned, drain any excess fat (I leave about 1 tbsp for flavor). Stir in the 1 whole yellow onion (diced), 1 whole bell pepper (diced), and 3 cloves garlic cloves (minced). Cook for 3-4 minutes until the vegetables soften and the onion turns translucent.

Sprinkle the 2 tbsp taco seasoning and 1 tsp salt over the mixture and stir well to coat. Add the 1 can diced tomatoes (with juices) and 1 can black beans (drained and rinsed). Simmer for 2-3 minutes until slightly thickened, then remove from heat.

Step 2: Prepare the Cheese Mixture

In a medium bowl, combine the 3 cups shredded cheddar cheese and 2 cups shredded Monterey Jack cheese. Mix well to distribute both types evenly—this blend gives you the perfect balance of sharpness and meltiness.

I like to reserve about ½ cup of this mixture for the top layer, ensuring a golden, bubbling finish. The rest will be sprinkled between the other layers for maximum cheesy goodness in every bite.

Step 3: Layer the Casserole for Maximum Flavor

Lightly grease a 9×13-inch baking dish to prevent sticking. Start by spreading half of the 2 cups corn tortilla chips (lightly crushed) on the bottom. Top with half of the beef and vegetable mixture, spreading it evenly.

Sprinkle one-third of the cheese mixture over the beef layer. Repeat with the remaining tortilla chips, beef mixture, and another third of the cheese. Finish with the remaining cheese and the reserved ½ cup—this final layer will get beautifully browned in the oven.

Step 4: Bake Until Bubbly and Golden

Preheat your oven to 375°F. Cover the casserole with aluminum foil and bake for 20 minutes. This step melts the cheese and lets the flavors meld together without drying out the top.

After 20 minutes, remove the foil and bake for another 10-15 minutes until the cheese is bubbling and golden brown and the edges are slightly crispy. You’ll know it’s ready when the cheese is fully melted and the casserole looks set around the edges.

Step 5: Rest, Garnish, and Serve

Let the casserole rest for 5-10 minutes after removing it from the oven. This allows the layers to set, making it easier to serve neat portions. While it rests, chop the 0.25 cup fresh cilantro for garnish.

Slice the 8 whole flour tortillas into strips or leave them whole for dipping. Serve the casserole hot, topped with a dollop of 0.5 cup sour cream and a sprinkle of fresh cilantro. The first bite should be warm, cheesy, and packed with Tex-Mex flavor in every layer.

Dietary Considerations for This mexican casserole recipe with ground beef

Gluten-Free Option

Swap the flour tortillas for certified gluten-free corn tortillas—I use Mission Gluten-Free brand. Also replace corn tortilla chips with gluten-free versions like Late July. Double-check your taco seasoning for hidden gluten; McCormick labels theirs clearly. 💡

Dairy-Free Adaptation

Use dairy-free cheese alternatives like Violife cheddar and monterey jack shreds. They melt beautifully at 375°F. For sour cream topping, Kite Hill makes an excellent almond-based version that tastes just like the real thing.

Lower-Carb Version

Replace corn tortilla chips with pork rinds for crunch. Use low-carb tortillas like La Tortilla Factory. Skip the beans and add extra bell peppers and zucchini to bulk up the vegetable layer.

Vegetarian Swap

Substitute 1.5 lb ground beef with 1.5 lb plant-based crumbles like Beyond Meat or Impossible. Add 1 tsp smoked paprika for depth. Use vegetarian refried beans instead of black beans for a creamier texture.

Lactose Intolerance

Use lactose-free cheeses like Sargento Ultra Thin cuts. They melt just as well. For topping, try coconut yogurt instead of sour cream—it adds a nice tang without dairy. I keep both on hand for guests with sensitivities. 🌱

Nut-Free Considerations

Ensure your dairy-free cheeses are nut-free if allergies are a concern. Daiya makes nut-free, dairy-free cheese shreds. Always check labels on seasoning packets for potential nut cross-contamination warnings.
