Step‑by‑Step Instructions for Sausage, Egg, Potato Breakfast Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While it warms up, grab a 9 x 13-inch baking dish and spray it generously with cooking spray. This will ensure that your savory casserole releases easily once it’s baked to golden perfection, making cleanup a breeze!
Step 2: Cook the Sausage and Vegetables
In a large skillet over medium-high heat, add the breakfast sausage and cook for about 5-7 minutes, breaking it apart as it cooks until no longer pink. Once the sausage is browned, toss in the green pepper, red pepper, onion, and minced garlic. Sauté this colorful mixture for an additional 5 minutes until the vegetables soften and become fragrant.
Step 3: Layer the Hash Browns
Now, let’s build the foundation of your Sausage, Egg, Potato Breakfast Casserole! Layer half of the thawed hash browns evenly across the bottom of the prepared baking dish. This layer of potatoes will provide that comforting structure to absorb all the delicious flavors to come.
Step 4: Add Sausage Mixture and Cheese
Next, sprinkle half of the sautéed sausage mixture over the hash browns, making sure it’s evenly distributed. Top this layer with 1 cup of shredded cheddar cheese, allowing the melty goodness to weave throughout the casserole, adding depth to each bite.
Step 5: Complete the Layers
Continue building your casserole by adding the remaining hash browns on top of the cheese. Then, carefully spread the rest of the sausage and vegetable mixture over the potatoes. Finally, finish with the remaining cheese, ensuring every inch is generously covered for a gooey, cheesy finish!
Step 6: Whisk the Egg Mixture
In a medium bowl, crack six large eggs and whisk them together with a splash of milk, salt, pepper, and red pepper flakes. Whisk until the mixture is pale yellow and slightly frothy; this will create the fluffy egg texture that binds your Sausage, Egg, Potato Breakfast Casserole together.
Step 7: Pour the Egg Mixture
Evenly pour the egg mixture over the prepared layering in the baking dish, ensuring it seeps down into the hash browns and sausage. This is where all the ingredients will come together during baking, creating a wonderful, cohesive dish.
Step 8: Bake to Perfection
Carefully place the baking dish into your preheated oven and bake for approximately 35 to 40 minutes. Keep an eye on the casserole as it bakes; it’s done when the eggs are fully set and the top is a beautiful golden brown.
Step 9: Garnish and Serve
Once you’ve removed the casserole from the oven, let it cool for a few minutes. Before serving, sprinkle chopped green onions over the top for a burst of freshness and color. Your Sausage, Egg, Potato Breakfast Casserole is now ready to be enjoyed—it’s a delightful slice of comfort on your breakfast table!
