Step 1: Preheat the Oven and Prepare the Baking Dish

• Preheat your oven to 375°F (190°C).
• Lightly grease a 9×13-inch casserole dish with cooking spray or olive oil.

Step 2: Cook the Sausage

1. Heat a large skillet over medium heat. Add the chicken sausage (or chorizo) and cook until browned, breaking it into small crumbles with a wooden spoon.
2. Stir in oregano, smoked paprika, chili powder, garlic powder, cumin, salt, pepper, and cayenne (if using). Let the spices cook for 1–2 minutes to enhance the flavor.
3. Remove the skillet from heat and set the sausage mixture aside.

Step 3: Layer the Casserole

1. Lay the tortillas in the bottom of the prepared baking dish, slightly overlapping to create a solid base.
2. Spread the black beans evenly over the tortillas.
3. Add the seasoned sausage mixture on top of the beans.
4. Pour the canned tomatoes and green chilies (do not drain) evenly over the sausage layer.
5. Drizzle the ranchero sauce over the top.
6. Sprinkle the shredded Mexican cheese blend evenly across the entire dish.

Step 4: Add the Eggs

1. Use a spoon to create 8 small wells in the cheese layer.
2. Crack one egg into each well, being careful not to break the yolks. Sprinkle a pinch of salt and pepper over the eggs.

Step 5: Bake the Casserole

1. Place the casserole in the preheated oven and bake for 25–30 minutes, or until the egg whites are fully set and the yolks reach your desired doneness.
2. For firmer yolks, bake for an additional 5 minutes.

Step 6: Garnish and Serve

1. Remove the casserole from the oven and let it cool for 5 minutes.
2. Garnish with chopped green onions and cilantro before serving.
3. Slice into portions and serve warm with your favorite toppings such as avocado, salsa, or sour cream.
