How to Make It
Step 1: Warm Up the Oven
Preheat your oven to 350°F. Lightly spray a 9×13 casserole dish with non-stick cooking spray and set it aside. This is where all the magic comes together.
Step 2: Build the Flavor Base
In a large skillet over medium heat, cook the ground beef and diced onion until the meat is browned and the onion is soft. This step sets the foundation for a protein-rich, family-style comfort meal.
Add the minced garlic and sauté for another 1–2 minutes, just until fragrant. Your kitchen should already start to feel cozy.
Step 3: Season and Simmer
Sprinkle in the taco seasoning and pour in the water. Stir well and let everything simmer briefly so the flavors fully combine.
Next, stir in the diced tomatoes with their juices, green chiles, and black beans. Heat through until everything is warm and well blended. This mixture is hearty, balanced, and perfect for a slow-down kind of dinner.
Step 4: Start Layering
Place 6 corn tortillas in the bottom of your prepared baking dish, overlapping slightly to cover the entire surface.
Spread ⅓ of the meat mixture evenly over the tortillas, then sprinkle 2 cups of shredded cheese on top.
Step 5: Repeat the Comfort
Repeat the layering process two more times tortillas, meat mixture, cheese creating three generous layers. Each one builds that cozy, satisfying texture that makes this dish so crave-worthy.
Step 6: Bake Until Bubbly
Cover the casserole with aluminum foil and bake for 30–40 minutes, until the cheese is fully melted and the edges are bubbly and irresistible.
