Crockpot Breakfast Casserole Ingredients For the Base • Eggs – Essential for structure and protein; use fresh eggs for the best results. • Milk – Adds creaminess; can substitute with almond or soy milk for a dairy-free option. • Hash Brown Potatoes – Provides the base and texture; frozen hash browns are recommended for convenience.

Step‑by‑Step Instructions for Crockpot Breakfast Casserole Step 1: Prepare the Crockpot Start by spraying the inside of your crockpot with non-stick cooking spray to prevent the casserole from sticking. Make sure to cover all surfaces evenly. This small but essential step will make your clean-up quick and easy after enjoying the delicious Overnight Crockpot Breakfast Casserole. Step 2: Mix the Cheeses In a mixing bowl, combine the shredded cheddar and pepper jack cheeses until well blended. Set this cheese mixture aside for later layering. The mix will provide a delightful creamy texture and flavorful kick, and it’s one of the highlights of your decadent crockpot breakfast casserole. Step 3: Combine the Sausage and Veggies In another bowl, mix together the cooked breakfast sausage, diced onions, and diced bell peppers. Ensure everything is evenly distributed, as this savory blend will add depth and aroma to your casserole. This mixture forms the flavor backbone, enhancing the overall experience of each slice of the breakfast casserole. Step 4: Whisk the Egg Mixture In a separate bowl, crack a dozen eggs and beat them until they are well blended. Gradually whisk in the milk, kosher salt, and black pepper, ensuring everything is combined thoroughly. This creamy egg mixture will hold your Crockpot Breakfast Casserole together and provide a fluffy texture once cooked. Step 5: Layer the Hash Browns Begin layering by placing one-third of the frozen hash brown potatoes at the bottom of the crockpot. Spread them evenly, creating a solid base. This foundation adds a satisfying, crispy texture to your breakfast casserole, setting the stage for the flavorful layers to come. Step 6: Add the Sausage Mixture Top the layer of hash browns with one-third of the sausage and veggie mixture. Distribute it evenly across the potatoes, ensuring that every bite will be packed with flavor. Follow this by sprinkling one cup of your cheese mixture on top to create a cheesy delight that complements the savory ingredients below. Step 7: Repeat the Layers Continue the layering process by adding another third of the hash browns, followed by the remaining sausage mixture and another cup of cheese. Repeat this step one last time, finishing off with the final third of hash browns for texture. Each layer builds on the flavors, inviting everyone to dive into this comforting breakfast. Step 8: Pour the Egg Mixture Once all layers are assembled, gently pour the egg mixture over the top of the entire casserole. This final step binds all the ingredients together and ensures that every corner of your crockpot is filled with flavor. Make sure to distribute it evenly so the eggs cook uniformly. Step 9: Cook the Casserole Set your crockpot to cook on low for about 8 hours. This slow cooking method will allow the flavors to meld beautifully while you enjoy a peaceful night’s sleep. In the morning, your kitchen will be filled with the wonderful aroma of the Overnight Crockpot Breakfast Casserole, enticing everyone to the table.
