Ingredients

• 10 pieces Large eggs
• 1 cup Whole milk
• 1 pound Ground breakfast sausage
• 1 cup Green chiles, roasted and diced
• 2 cups Shredded cheddar cheese
• 8 pieces Corn tortillas
• 1 medium Onion, diced
• 2 cloves Garlic, minced
• 1 teaspoon Salt
• 1 teaspoon Ground cumin
• 0.5 teaspoon Black pepper
• 1 tablespoon Butter or cooking spray (for greasing)

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or cooking spray.

Step 2

In a large skillet over medium heat, cook the ground sausage until browned and fully cooked, breaking it apart into crumbles with a spatula. Remove the sausage and set aside, leaving about 1 tablespoon of rendered fat in the skillet.

Step 3

In the same skillet, sauté the diced onion until softened and translucent, about 3-4 minutes. Add the minced garlic and cook for another 1 minute, stirring constantly.

Step 4

Add the roasted green chiles, cooked sausage, ground cumin, salt, and black pepper to the skillet. Mix well and cook for an additional 2 minutes. Remove from heat and set aside.

Step 5

In a mixing bowl, whisk together the eggs and milk until fully combined. Set aside.

Step 6

Layer 4 corn tortillas at the bottom of the greased baking dish, tearing them as needed to cover the base evenly.

Step 7

Spread half of the sausage and green chile mixture over the tortillas. Sprinkle 1 cup of shredded cheddar cheese evenly over the layer.

Step 8

Repeat the layers with the remaining 4 tortillas, sausage-green chile mixture, and 1 cup of shredded cheddar cheese.

Step 9

Pour the egg and milk mixture evenly over the entire dish, allowing it to soak through the layers.

Step 10

Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.

Step 11

Remove the foil and bake uncovered for another 15 minutes, or until the top is golden and the casserole is set in the center.

Step 12

Let the casserole rest for 5-10 minutes before slicing and serving. Enjoy with your favorite toppings such as salsa, sour cream, or fresh cilantro!
