Beefy Fiesta Tortilla Casserole for Quick Weeknight Dinners Step-by-step instructions

Before you start

Before beginning the cooking process, ensure that all necessary ingredients are gathered and prepared. Grate your cheddar cheese if using a block, and measure out the ground beef and tortillas.

Having a clean workspace and all equipment within reach, such as your skillet and casserole dish, will make the assembly process much smoother. Preheat the oven early to ensure it reaches the target temperature, allowing the casserole to begin cooking immediately upon assembly.

Instructions

Preparation of the beef

1. 1Cook the ground beef
   Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until it is fully browned and no longer pink. Ensure the beef reaches an internal temperature of 160°F (71°C) to be considered safe.
   Look for The beef should be browned and well-crumbled with no visible pink areas remaining.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Drain any excess grease from the skillet before assembling the casserole to keep the dish from becoming too oily.

The ground beef should be thoroughly browned and crumbled, with no pink pieces remaining. Ensure the excess fat is drained from the skillet before you begin the layering process. The beef should be aromatic and ready for assembly, providing a flavorful foundation for the rest of the ingredients in the casserole.

Layering the casserole

2. 2Layer the casserole
   Preheat your oven to 375°F (190°C). In a 9x13 inch casserole dish, place a layer of flour tortillas on the bottom. Spread a portion of the cooked ground beef over the tortillas, then sprinkle generously with the shredded cheddar cheese. Repeat these layers until all ingredients are used, finishing with a final layer of cheese on top.
   Look for Ensure the final layer of cheese covers the surface completely for an even, golden melt.
   Tip Overlap the tortillas slightly if necessary to ensure every bite of the casserole has a sturdy base.

Check that your layers are distributed evenly, ensuring that each layer of tortilla is covered by a sufficient amount of beef and cheese. The final layer of cheese should cover the surface entirely to ensure a uniform golden crust. The dish should feel substantial and well-packed before it goes into the oven.

Baking until golden

3. 3Bake and serve
   Place the casserole dish into the preheated oven and bake for 20 minutes, or until the cheese is bubbling and slightly golden brown. Remove from the oven and let it rest for 5 minutes before slicing and serving. This resting period helps the layers set properly.
   Look for The cheese should be melted and bubbling throughout with crisp edges.
   Tip Use a sharp knife to slice through the tortillas cleanly, ensuring each portion holds its shape when lifted with a spatula.

The casserole is ready when the cheese is bubbling and the top has developed a golden hue. The edges will be slightly crisp and pull away from the sides of the dish.

After the resting period, the casserole should be easy to slice, with each portion showing distinct, appetizing layers of beef, tortilla, and cheese.

Common mistakes

A common mistake is failing to drain the excess grease from the skillet after browning the ground beef. This can lead to a greasy casserole with an oily texture. Another error is skipping the rest time after removing the dish from the oven.

Allowing the casserole to rest for at least 5 minutes is crucial, as it helps the cheese and fillings set, preventing the portions from falling apart when you lift them out with your spatula.

How to tell it’s done

The casserole is done when the cheese is fully melted, bubbling across the entire surface, and has reached a light golden-brown color. The edges should appear slightly crisp.

Because the ground beef is pre-cooked to 160°F (71°C), the baking time is primarily to heat the entire dish through and melt the cheese. A thermometer inserted into the center of the casserole should register at least 165°F (74°C) to ensure it is thoroughly heated.
