Ingredients

Scale

12 large eggs

1 1/2 cups whole milk

1 pound ground breakfast sausage

6 flour tortillas (8-inch), torn into pieces

1 1/2 cups shredded cheddar cheese

1 cup shredded Monterey Jack cheese

1/2 cup diced green chiles

1 small onion, chopped

1 teaspoon garlic powder

1 teaspoon ground cumin

1/2 teaspoon salt

1/2 teaspoon black pepper

Fresh cilantro or green onions, for garnish (optional)


Instructions

1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.

2. In a skillet over medium heat, cook sausage until browned. Add chopped onions and cook until soft. Drain excess fat.

3. In a large bowl, whisk together eggs, milk, garlic powder, cumin, salt, and pepper until well combined.

4. Layer torn tortillas in the baking dish. Add sausage and onion mixture, shredded cheeses, and green chiles. Repeat until all ingredients are used.

5. Slowly pour egg mixture over the layered ingredients in the dish, letting it seep into all layers.

6. If possible, cover and let it rest in the fridge for 30 minutes or overnight to enhance flavor and texture.

7. Bake uncovered for 40–45 minutes, until the center is set and top is golden. Tent with foil if it browns too quickly.

8. Remove from oven and let rest for 5–10 minutes before slicing. Garnish with cilantro or green onions if desired.

Notes

Use toasted or day-old tortillas to help avoid a soggy texture.

For extra spice, add diced jalapeños or use spicy sausage.

Let the casserole cool slightly before cutting for cleaner slices.
