Waking up to the aroma of a freshly baked breakfast casserole is like receiving a warm hug on a chilly morning. This easy overnight Mexican breakfast casserole is a fiesta in a dish—bursting with vibrant flavors, a touch of spice, and a whole lot of comfort. Imagine savoring this while the world outside is just waking up, birds still groggy with dreams.
Steps
- Preheat your oven to 400°F (200°C) and lightly coat a 9 x 13-inch baking dish with cooking spray.
- Cook the sausage in a large pan over medium-high heat until it browns, breaking it into crumbles. Transfer the cooked sausage to a plate, leaving a small amount of grease in the pan.
- Sauté the diced onion and pepper in the same pan for about 5 minutes until they soften. Add minced garlic and cook for an additional 1-2 minutes until aromatic.
- Incorporate the salsa, beans, corn, cumin, salt, and the cooked sausage into the pan. Stir until thoroughly combined, then remove from heat.
- In a separate bowl, whisk together the eggs and milk until they are uniformly mixed.
- Begin layering in the prepared baking dish: start with half of the tortillas, then spread half of the sausage mixture, followed by half of the egg mixture, and half of the cheese. Repeat with the remaining ingredients for a second layer.
- Cover the dish with foil and bake for 45-50 minutes, or until the casserole is set in the center and does not wobble. A toothpick inserted should come out clean.
- Allow the casserole to cool on a wire rack for about 10 minutes. Add your preferred toppings, slice, and serve while warm.
