Prepare the Baking Dish: Preheat the oven to 350°F. Spread a thin layer of enchilada sauce evenly across the bottom of a 9x13 baking dish.
Assemble the Enchiladas: Set up an assembly line with tortillas, enchilada sauce, beef mixture, and cheese. Take a tortilla, spread 2 tablespoons of enchilada sauce evenly over the surface, add 1/2 to 2/3 cup of the beef mixture in a straight line near one edge (where you’ll start rolling), and sprinkle with 1/3 cup of cheese.
Roll and Arrange the Enchiladas: Roll up the tortilla tightly and place it seam-side down in the prepared 9x13-inch baking dish. Repeat with the remaining tortillas, filling the dish as you go.
Top the Enchiladas: Evenly spread the remaining enchilada sauce (about 1 ¾ cups) over the assembled enchiladas, then sprinkle with the remaining cheese (about 1 ½ to 2 cups).
Bake the Enchiladas: Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and golden brown.
Serve the Enchiladas: Serve immediately while they’re hot and melty, topped with your favorite toppings.
