Cheesy Beef Tortilla Casserole Pie with Garlic Butter Crust

This Cheesy Beef Tortilla Casserole Pie stacks golden tortillas with a seasoned ground beef filling, then blankets everything in a molten mozzarella-cheddar topping.

Brushed with garlic parsley butter and baked until crisp and bubbly, it delivers all the comforting flavors of a taco night in one easy, sliceable dish. Perfect for weeknight dinners or casual gatherings, this pie is as impressive as it is simple to make.

Layered like a lasagna but with tortillas, this casserole pie brings together a hearty beef filling with onions, bell peppers, and a smoky spice blend. The tortillas soften as they bake, absorbing the juices from the beef while the top turns golden and crisp under a layer of garlic butter and cheese.

Each slice is a satisfying stack of textures, from the tender interior to the chewy, slightly crunchy edges. Serve it straight from the oven for the full cheese-pull effect.

Ingredients

Why this recipe works

The method of layering tortillas with a well-seasoned beef mixture ensures every bite is evenly filled with flavor. The tortillas act as both a structural element and a starch, holding the filling together so the pie slices cleanly. As the pie bakes, the tortillas absorb moisture from the beef, becoming tender while the top layer crisps up under the garlic butter and cheese, creating a pleasing contrast of textures.

Baking at 380°F (193°C) allows the cheese to melt slowly and evenly without burning, giving the top a deep golden color and a bubbly, molten surface. The garlic butter brushed on the top tortilla adds an extra layer of savory richness and helps the surface brown beautifully. This method ensures the filling is hot throughout and the flavors meld together into a cohesive, comforting dish.

Notes and substitutions

Use a good-quality ground beef with about 80/20 lean-to-fat ratio for the most flavorful filling. The fat renders out during browning, keeping the meat moist. If using a leaner blend, add a tablespoon of olive oil to the skillet.

The onion and bell pepper add sweetness and texture, while the smoked paprika and cumin provide a warm, earthy depth. Adjust the salt to taste, keeping in mind that the cheeses add saltiness.

Flour tortillas are the classic choice for this casserole, but corn tortillas can be used for a different flavor and texture. For a gluten-free version, ensure the tortillas are certified gluten-free.

The garlic parsley butter can be made by melting butter and stirring in minced garlic and chopped parsley, or use a store-bought version. Shred your own cheese from a block for the best melting, as pre-shredded varieties often contain anti-caking agents that affect texture.
