Before you start

Before starting, organize all ingredients and equipment on the counter to ensure a smooth assembly process. Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius). Measure out the ground beef, taco seasoning, refried beans, and shredded cheese.

Lightly grease a nine-by-thirteen-inch baking dish with nonstick cooking spray. If the refried beans are too stiff to spread easily, transfer them to a microwave-safe bowl and warm them for thirty seconds to loosen their texture. This preparation makes layering quick and effortless.

Ingredients at a glance (5)
  • 1 lb ground beef
  • 1 oz taco seasoning
  • 15 oz refried beans
  • 8 flour tortillas
  • 2 cups shredded Mexican cheese blend

Instructions

Browning and Seasoning the Beef

  1. Brown the Beef
    Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spatula, until it is completely browned and no longer pink.
    Look for The beef should be fully browned and crumbled, taking about 6 to 8 minutes.
    Tip Drain any excess grease from the skillet after browning to keep the lasagna from becoming soggy.
  2. Season and Simmer
    Stir the taco seasoning into the browned beef. Reduce the heat to low and simmer the beef in its own juices with the seasoning until thoroughly coated and fragrant, ensuring the beef reaches a safe internal temperature of 160°F (71°C).
    Look for The sauce should thicken and cling to the beef, taking about 3 to 5 minutes.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Keep the beef moist but not watery so the lasagna layers hold their shape.

At the end of this phase, the ground beef is fully browned, crumbled, and coated in a thick, savory taco sauce. There should be no pink meat remaining, and the mixture should smell highly aromatic with hints of cumin, chili powder, and garlic. The sauce should be simmered down so it is moist but not watery.

Assembling the Lasagna Layers

  1. Create the Base Layer
    Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish. Place a layer of flour tortillas at the bottom of the dish, cutting them if necessary to fit. Spread half of the refried beans evenly over the tortillas.
    Look for The tortillas should completely cover the bottom of the baking dish.
    Tip Warm the refried beans slightly in the microwave for 30 seconds to make them easier to spread.
  2. Layer Beef and Cheese
    Spread half of the seasoned ground beef over the refried beans, then sprinkle with one-third of the shredded Mexican cheese blend. Repeat the layers, starting with tortillas, followed by the remaining refried beans, remaining beef, and another third of the cheese. Finish with a final layer of tortillas and the remaining cheese on top.
    Look for The top should be covered with an even layer of shredded cheese.
    Tip Press down gently on each tortilla layer to compact the lasagna and prevent air pockets.

The assembled lasagna should show neat, even layers of flour tortillas, spreadable refried beans, seasoned beef, and shredded cheese, filling the baking dish almost to the top. The final layer must be a generous, even blanket of shredded cheese covering the tortillas completely to prevent them from burning.

Baking to Cheesy Perfection

  1. Bake Until Bubbly
    Bake in the preheated oven for 20 to 25 minutes, or until the cheese on top is completely melted, bubbly, and lightly golden brown. Remove from the oven and let rest for 10 minutes before slicing.
    Look for The cheese should be deeply melted, golden, and bubbling around the edges.
    Tip Letting the lasagna rest is crucial; it allows the layers to set so slices clean and neat.

The lasagna emerges from the oven with a spectacular, golden-brown cheese crust that bubbles actively around the edges of the dish. A gentle press on the top reveals a soft, tender interior, and a delicious aroma of toasted cheese and seasoned beef fills the kitchen.

Common mistakes

A common mistake is failing to drain the ground beef after browning, which can lead to a greasy, watery lasagna. Always drain excess fat before adding the seasoning. Another error is over-baking the casserole, which dries out the tortillas and makes the cheese topping tough instead of gooey.

Additionally, skipping the resting period after baking is a frequent misstep; slicing the lasagna immediately will cause the layers to slide apart. Letting it rest allows the ingredients to set into neat, beautiful portions.

How to tell it’s done

This lasagna is fully cooked and ready when the cheese topping is completely melted, bubbly in the center, and lightly golden brown around the edges.

The internal temperature of the seasoned ground beef must reach a safe 160 degrees Fahrenheit (71 degrees Celsius) during the initial skillet cooking phase to ensure safety.

When inserting a knife into the center of the baked casserole, it should slide in easily and come out hot, indicating that the heat has penetrated all the layers thoroughly.
