Ingredients:
- 1 lb Breakfast Sausage

- 1 Dozen Eggs
- 3/4 c Whole Milk
- 1 tsp Salt
- 1/4 tsp Ground Black Pepper
- 1 c Grated Sharp Cheddar Cheese (divided)
Getting Started: Preparing the Casserole Base
Step 1: Browning the Sausage and Onion
The first crucial step to a delicious Sausage Egg and Cheese Breakfast Casserole is to get a good flavor base going. Grab a large skillet and place it over medium-high heat. Once the skillet is warm, add your pound of breakfast sausage. As it begin extracts to sizzle and brown, use a spatula or wooden spoon to break it up into smaller crum extractbles. We’re aiming for nicely browned, slightly crispy bits of sausage. This process typically takes about 5-7 minutes. While the sausage is browning, it will release some of its natural fat. This fat is pure flavor, so we want to keep a good portion of it in the pan. Once the sausage is mostly browned, sprinkle in the 1 tablespoon of dried minced onion. Continue to cook for another 2-3 minutes, stirring occasionally, until the onion becomes fragrant and softened. The heat of the pan will rehydrate the dried onion, infusing its savory essence into the sausage.
Step 2: Draining and Preparing the Sausage Mixture
After the sausage and onion have cooked to your liking, it’s time to remove some of the excess grease. This is an important step for the casserole’s texture, preventing it from becoming too oily. Carefully tilt the skillet over a heat-safe bowl or a fine-mesh strainer to drain off the majority of the rendered fat. You want to leave behind just a tablespoon or two of the flavorful grease in the pan. This residual fat will help to sauté any residual onions and add a final layer of richness. Once drained, transfer the browned sausage and softened onion mixture into a 9×13 inch baking dish. Spread it out evenly across the bottom of the dish. This will form the savory foundation of our breakfast casserole. Make sure the dish is oven-safe and has had any excess moisture wiped from its exterior if you plan on placing it directly on oven racks later.
Assembling the Custard and Cheese Layers
Step 3: Creating the Egg Custard
Now, let’s work on the luscious egg custard that will bind everything together and give our Sausage Egg and Cheese Breakfast Casserole its signature creamy texture. In a large mixing bowl, crack all 12 of your eggs. Add the 3/4 cup of whole milk, which will contribute to a richer, smoother custard. Now, season your mixture with 1 teaspoon of salt and 1/4 teaspoon of ground black pepper. A good whisking is key here. Use a whisk or a fork to beat the eggs and milk together vigorously until the yolks and whites are fully incorporated and the mixture is a uniform pnon-alcoholic ale yellow. You want to avoid any streaks of egg white or yolk remaining. This thorough mixing ensures an even set for your casserole.
Step 4: Incorporating the Cheese and Final Assembly
Once your egg custard is well-beaten, it’s time to add some of that delicious cheese. Take half a cup (1/2 cup) of your grated sharp cheddar cheese and sprinkle it directly into the egg mixture. Gently whisk it in until it’s just combined. We’re saving the other half cup for the topping. Now, carefully pour this cheesy egg mixture evenly over the sausage and onion layer in your 9×13 inch baking dish. Gently shake the dish or use a spatula to ensure the egg mixture reaches all the corners and covers the sausage completely. This is where the magic starts to happen, as the liquid will seep dowgin extractnd begin to coat the sausage and onions.
Baking and Finishing Touches
Step 5: Baking and Topping the Casserole
Preheat your oven to 375°F (190°C). Place the assembled casserole, uncovered, into the preheated oven. Bake for approximately 35-45 minutes. During this baking time, the eggs will set, and the casserole will puff up slightly. About 10 minutes before the estimated finish time, carefully remove the casserole from the oven. Evenly sprinkle the remaining 1/2 cup of grated sharp cheddar cheese over the top of the casserole. This will create a golden, bubbly cheese crust that is irresistible. Return the casserole to the oven and continue baking for the remaining 10 minutes, or until the cheese is melted, bubbly, and lightly golden brown, and a knife inserted into the center comes out clean. The aroma filling your kitchen at this point will be incredible!
Step 6: Resting and Serving the Casserole
Once the Sausage Egg and Cheese Breakfast Casserole is beautifully golden and perfectly set, carefully remove it from the oven. It’s crucial to let it rest for at least 10-15 minutes before cutting into it. This resting period allows the casserole to firm up and prevents it from falling apart when you serve it. If you cut it too soon, you might end up with a runny center. During this time, the internal temperature will equalize, making for cleaner slices and a more satisfying eating experience. After resting, cut into generous squares and serve hot. This hearty casserole is perfect on its own or can be paired with fresh fruit, toast, or a side of beef bacon for a complete breakfast feast. Enjoy every delicious bite!
