Ingredients:
- 1 lb Breakfast Sausage
- 1 tbs Dried Minced Onion
- 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 Base
The foundation of a truly great Sausage Egg and Cheese Breakfast Casserole lies in properly preparing your sausage and ensuring a rich, flavorful egg mixture. This initial stage sets the stage for a dish that will be savory, satisfying, and perfect for any brunch or busy morning. We’ll start by cooking the breakfast sausage. In a large skillet, over medium heat, break apart the 1 lb of breakfast sausage. Cook it, stirring occasionally, until it is nicely browned and no pink remains. This process typically takes about 8-10 minutes. It’s important to ensure the sausage is fully cooked through to avoid any textural issues or potential food safety concerns later on. As the sausage cooks, you’ll want to drain off most of the excess grease. You can do this by tilting the skillet and spooning out the grease, or by carefully transferring the cooked sausage to a plate lined with paper towels to absorb the fat. Leave just a tablespoon or so of the rendered sausage fat in the skillet; this will be used to sauté the dried minced onion, infusing it with even more delicious sausage flavor.
Once the sausage is drained and set aside, add the 1 tbs of dried minced onion to the skillet with the reserved sausage fat. Sauté the onion over medium-low heat for about 2-3 minutes, stirring frequently. You’re not looking to brown the onion significantly, but rather to rehydrate it and release its aromatic qualities into the sausage fat. This simple step adds a wonderful depth of savory flavor that dried onions can provide when bloomed in fat. After sautéing, remove the skillet from the heat. Now, gently stir in the cooked and drained breakfast sausage with the sautéed onions. Mix them together well to ensure the onion is evenly distributed throughout the sausage. This sausage and onion mixture will form the savory, meaty layer of our breakfast casserole.
Crafting the Custard: The Egg Mixture
While the sausage mixture is cooling slightly, it’s time to prepare the rich and creamy custard that will bind everything together and create that signature fluffy texture of a Sausage Egg and Cheese Breakfast Casserole. In a large bowl, crack the 1 dozen eggs. It’s a good idea to use a bowl that is generously sized, as you’ll be whisking vigorously and need ample space. Add the 3/4 cup of whole milk to the eggs. The whole milk is crucial here as it provides a richer, more decadent texture compared to lower-fat alternatives. Next, season the mixture with 1 tsp of salt and 1/4 tsp of ground black pepper. These seasonings are fundamental to bringing out the flavors of the eggs and the sausage. Whisk the eggs, milk, salt, and pepper together until they are thoroughly combined and the yolks and whites are fully incorporated. You want a smooth, homogenous mixture with no streaks of egg white visible. For an even more luxurious texture, you can whisk for a full minute or two, ensuring a good amount of air is incorporated, which will contribute to a lighter, fluffier finished casserole.
Now, it’s time to incorporate some of that delicious cheese. Take about half of your grated sharp cheddar cheese, which is approximately 1/2 cup, and gently fold it into the whisked egg mixture. Stir just until the cheese is evenly distributed. You don’t want to overmix at this stage; we just want to ensure pockets of cheesy goodness throughout the casserole. The remaining 1/2 cup of grated sharp cheddar cheese will be used for topping the casserole later, creating that irresistible golden-brown, bubbly cheese crust.
Assembling and Baking the Casserole
With both the sausage mixture and the egg custard prepared, we’re ready to assemble this magnificent Sausage Egg and Cheese Breakfast Casserole. First, preheat your oven to 375°F (190°C). While the oven is heating, lightly grease a 9×13 inch baking dish with butter or cooking spray. This step is essential to prevent the casserole from sticking and to ensure easy removal after baking.
Now, evenly distribute the sausage and onion mixture across the bottom of the prepared baking dish. Spread it out so you have a consistent layer of savory goodness in every bite. Next, carefully pour the egg and cheese mixture over the sausage layer. Gently tilt the baking dish to allow the egg mixture to flow into all the nooks and crannies, ensuring that the sausage is completely covered. This will create a beautiful, unified casserole.
Finally, sprinkle the remaining 1/2 cup of grated sharp cheddar cheese evenly over the top of the egg mixture. This is where the magic happens, as the cheese will melt and turn golden brown during baking, creating a delicious and visually appealing crust. Place the assembled casserole into the preheated oven. Bake for 35-45 minutes, or until the eggs are set and the cheese on top is melted and bubbly and lightly golden brown. You can test for doneness by inserting a knife into the center of the casserole; it should come out clean. If the cheese on top is browning too quickly before the eggs are set, you can loosely tent the dish with aluminum foil.
Resting and Serving: The Grand Finale
Once your Sausage Egg and Cheese Breakfast Casserole is out of the oven and looking absolutely perfect, it’s important to let it rest for a few minutes before serving. Allow the casserole to sit on a wire rack for at least 10 minutes. This resting period is crucial because it allows the casserole to set up properly. If you cut into it immediately, it might be a bit too loose and could fall apart. The resting time lets the cooked eggs firm up, resulting in cleaner slices and a more stable, satisfying texture. After resting, cut the casserole into squares and serve hot. This Sausage Egg and Cheese Breakfast Casserole is wonderful on its own, or it can be paired with fresh fruit, toast, or a side of bacon for a complete breakfast or brunch experience. Enjoy every savory, cheesy bite!
