It’s perfect for holiday mornings, brunch parties, or meal prepping your breakfasts for the week.
Why This Recipe Works·
Hands-Off Cooking: No standing over a flipping skillet. Just mix, pour, and bake.
· Versatile: You can swap the sausage for ham or the cheddar for pepper jack.
· Portable: Because it’s baked in an aluminum pan, it travels perfectly to potlucks or family gatherings.
—The Full Recipe
Prep Time: 15 minutes
Cook Time: 45–50 minutes
Total Time: 1 hour 5 minutes
Yield: 8-10 servings
Ingredients·
. 1 lb bulk breakfast sausage (mild or spicy)
· 6-8 slices thick-cut bacon, chopped into small pieces (plus extra for garnish if desired)
· 10 large eggs
· 1 cup whole milk or half-and-half (for extra creaminess)
· ½ tsp salt
· ½ tsp black pepper
· ½ tsp garlic powder
· 1 (4 oz) can diced green chilies (drained) – visible as the green flecks in the image
· 2 cups shredded sharp cheddar cheese (divided)
· 1 cup shredded Monterey Jack cheese (optional, for extra melty texture)
Instructions
Step 1: Prepare the Meat Base
Preheat your oven to 375°F (190°C). In a large skillet over medium-high heat, cook the breakfast sausage and chopped bacon together. Break up the sausage with a spatula as it cooks. Cook until the meat is browned and cooked through (about 8-10 minutes). Use a slotted spoon to transfer the meat to a paper towel-lined plate to drain off excess grease. Do not skip this step, or your casserole will be oily.
Step 2: Mix the Egg Base
In a large mixing bowl, whisk the eggs vigorously until they are light yellow and uniform. Whisk in the milk, salt, pepper, and garlic powder. Stir in the drained green chilies and 1 cup of the shredded cheddar cheese (save the other cup for the top). Mix in the cooked sausage and bacon (reserve a small handful of bacon for the garnish).
Step 3: Assemble the Casserole
Lightly grease a 9×13-inch disposable aluminum baking pan (or a standard glass casserole dish). Pour the egg and meat mixture into the pan and smooth the top evenly.
Step 4: Bake
Place the pan in the preheated oven and bake uncovered for 35 minutes.
Step 5: Add the Cheese ToppingAfter 35 minutes, carefully remove the pan from the oven. Sprinkle the remaining 1 cup of cheddar cheese evenly over the top (this creates that golden crust). Sprinkle the reserved chopped bacon on top of the cheese, as seen in your photo.
Step 6: Finish Baking
Return the pan to the oven and bake for an additional 10-15 minutes, or until the cheese is melted, bubbling, and slightly golden. The casserole is done when a knife inserted in the center comes out clean (or the center temperature reaches 160°F).
Step 7: Rest and Serve
Let the casserole rest for 5-10 minutes before cutting. This allows it to set up so you get clean squares. Serve with salsa, sour cream, or hot sauce on the side.
Chef’s Tips:
· For a crispier bacon top: After adding the bacon garnish in Step 5, turn the oven to Broil for the final 1-2 minutes. Watch it closely so it doesn’t burn!·
Make it ahead: You can assemble this entirely the night before. Cover with foil and refrigerate. In the morning, bake as directed, adding about 10-15 minutes to the initial baking time since the ingredients will be cold.
Store leftovers: Cover the pan with foil or transfer pieces to an airtight container. It will keep in the fridge for up to 4 days and reheats beautifully in the microwave.
