Step‑by‑Step Instructions for Slow Cooker Breakfast Casserole
Step 1: Cook the Sausage
In a skillet over medium heat, brown 1 pound of breakfast sausage, breaking it apart with a spatula until fully cooked, about 5-7 minutes. Ensure there is no pink remaining and drain any excess grease for a cleaner taste. The sausage adds a hearty base to your Slow Cooker Breakfast Casserole, so savor those moments of cooking!
Step 2: Mix Eggs and Seasoning
In a large mixing bowl, whisk together 8 large eggs, 1 cup of milk, ½ teaspoon of salt, ¼ teaspoon of black pepper, and ½ teaspoon of garlic powder until everything is fully combined and fluffy, about 1-2 minutes. This egg mixture is crucial—the creamy texture will bind all ingredients seamlessly in the Slow Cooker Breakfast Casserole.
Step 3: Prepare Slow Cooker
Lightly grease the slow cooker with cooking spray or a drizzle of olive oil to prevent sticking. Layer 4 cups of thawed hash browns evenly across the bottom, creating a solid base for your casserole. The hash browns will crisp slightly on the edges, enhancing the texture of the Slow Cooker Breakfast Casserole.
Step 4: Layer Ingredients
Sprinkle the cooked sausage evenly over the hash browns, topping it with 1 diced bell pepper and ½ cup of chopped onion. The colors will be inviting and aromatic! This layering is essential, setting the stage for robust flavors that meld beautifully as the casserole cooks.
Step 5: Add Egg Mixture
Pour the egg mixture evenly over the layered ingredients in the slow cooker, ensuring all components are covered. This step is key; it locks in the flavor and moisture, transforming your Slow Cooker Breakfast Casserole into a delightful breakfast bake that everyone will enjoy.
Step 6: Cheese Layer
Sprinkle 1 ½ cups of shredded cheddar cheese generously on top of the casserole. As it melts during cooking, the cheese will create a deliciously gooey layer that is the star of the Slow Cooker Breakfast Casserole. Make sure the cheese covers all the ingredients to enhance flavor.
Step 7: Cook
Cover the slow cooker with its lid and set it to cook on low for 6-7 hours or on high for 3-4 hours. You'll know it's ready when the eggs are set and the top is beautifully golden; the aroma of breakfast will fill your kitchen—a sign of delightful meals to come.
Step 8: Finish Cooking
In the final 10-15 minutes of cooking, sprinkle the remaining ½ cup of cheese on top and cover again. This extra layer of cheese will melt into a bubbly, cheesy delight, adding a delicious finish to your Slow Cooker Breakfast Casserole that everyone will love.
Step 9: Rest Before Serving
Once cooked, let the casserole sit for 5 minutes before serving. This resting period allows the flavors to settle, making it easier to slice. For that extra touch, consider topping it with fresh chopped parsley or cilantro to enhance the presentation and flavor of your breakfast dish.
