Preheat your oven to 375°F (190°C). Gather your ingredients and an oven-safe baking dish.

In a skillet over medium heat, cook the ground beef until browned, about 6–8 minutes. Drain excess fat and season if desired.

Spread a layer of cooked ground beef over half of a tortilla. Sprinkle with shredded cheese, then fold the tortilla in half. Repeat for remaining tortillas.

In the baking dish, place the folded tortillas side by side. Add a dollop of sour cream on top of each.

Bake in the preheated oven for about 15–20 minutes, until cheese is bubbling and tortillas are golden brown.

Remove the dish from the oven, let it cool slightly, then cut into squares or wedges and serve warm.
