Easy Cheesy Mexican Tortilla Casserole Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are measured and ready to go. Drain and rinse the black beans thoroughly to remove excess starch.

Preheat your oven to 375°F (190°C) so that it is at the correct temperature once the assembly is complete.

Having your baking dish and spatula within reach will streamline the entire process, making the transition from stovetop to oven quick and efficient.

Instructions

Browning the base

1. 1Prepare the meat filling
   Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it into crumbles with a spatula, until it is browned and reaches an internal temperature of 160°F (71°C). Drain any excess fat if necessary. Stir in the black beans and cook for another two minutes until heated through.
   Look for The beef should be fully browned and no longer pink.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Season the beef with your favorite taco spices during browning for extra flavor.

The ground beef should be completely browned with no visible pink remaining, and the black beans should be well incorporated and heated through. The mixture should be fragrant and consistent in texture, ready to be layered into the baking dish.

Layering the ingredients

2. 2Assemble the casserole
   Preheat the oven to 375°F (190°C). In a 9x13 inch glass baking dish, place a layer of flour tortillas on the bottom. Spread half of the ground beef and black bean mixture over the tortillas. Sprinkle a portion of the shredded cheese on top. Repeat the layers with the remaining tortillas, meat mixture, and the rest of the cheese.
   Look for Ensure the cheese covers the entire surface evenly for a good melt.
   Tip Tear the tortillas into smaller pieces if necessary to fit the dish perfectly.

The dish should be neatly assembled with distinct layers of tortillas, meat, and cheese. Ensure that the top layer of cheese is spread evenly to the edges of the dish to guarantee a consistent melt during the baking phase.

Baking to perfection

3. 3Bake and serve
   Place the baking dish in the preheated oven and bake for approximately 20 minutes, or until the cheese is bubbling and golden brown. Remove the dish from the oven and allow it to rest for 5 minutes before slicing. This helps the layers set and makes serving much easier.
   Look for The cheese should be melted, bubbly, and slightly browned on the edges.
   Tip Watch the oven closely during the last few minutes to prevent the cheese from burning.

The casserole should look golden and bubbly, with the cheese fully melted and slightly browned. The entire dish should be hot throughout, and it should smell savory and appetizing, indicating it is ready to be removed from the oven.

Common mistakes

A common mistake is overcrowding the baking dish or failing to drain the ground beef properly, which can lead to a watery casserole. Always drain the excess fat after browning the meat.

Another oversight is rushing the resting period; if you cut into the dish too soon, the layers may slide apart. Patience during these few minutes ensures a beautiful serving every single time.

How to tell it’s done

The casserole is finished when the cheese is fully melted, bubbling across the entire surface, and has reached a golden-brown color in spots.

The internal temperature of the beef mixture should have reached 160°F (71°C) during the initial browning phase. The edges of the tortillas should feel slightly firm, and the dish should look cohesive and heated through when poked with a fork.
