How to Make Crockpot Breakfast Casserole

This Crockpot Breakfast Casserole is simple to assemble and requires very little hands-on time. Just layer the ingredients, pour in the egg mixture, and let the slow cooker do all the work.

Step 1: Prepare the Crockpot

Generously spray a 6 to 7-quart crockpot with nonstick cooking spray. This prevents sticking and makes cleanup easier.

Step 2: Add the Hash Browns

Spread the frozen O’Brien hash browns evenly across the bottom of the prepared crockpot. This layer forms the sturdy base of the casserole.

Step 3: Add the Vegetables

Sprinkle the diced green bell pepper, red bell pepper, and sweet onion evenly over the hash browns. This creates a flavorful and colorful layer.

Step 4: Add the Meats

Distribute the cooked and crumbled sausage and bacon evenly over the vegetables. This ensures every serving gets plenty of savory flavor.

Step 5: Add the Cheese

Sprinkle the freshly shredded cheddar cheese evenly over the meat layer, creating a rich, melty middle layer.

Step 6: Mix the Eggs

In a large mixing bowl, whisk together the eggs, half and half, onion powder, kosher salt, and cracked black pepper until fully combined.

Step 7: Assemble and Cook

Pour the egg mixture evenly over the cheese layer. Cover and cook on low for 8 hours, until the eggs are fully set and the casserole is tender and fluffy.

Step 8: Serve

Serve hot straight from the crockpot. This dish is perfect on its own or paired with fresh fruit, toast, or a light salad.

Tips to Succeed

Spray the crockpot generously with nonstick cooking spray to prevent sticking and make cleanup easier.

Use freshly shredded cheese instead of pre-shredded for better melting and smoother texture.

Cook meats fully before adding them to the slow cooker. This ensures food safety and prevents excess grease.

Layer ingredients evenly so the casserole cooks uniformly and each serving has balanced flavor.

Cook on low heat only. High heat may cause uneven cooking and dry eggs.

Avoid lifting the lid during cooking, as this releases heat and increases cooking time.

Let the casserole rest for 10 minutes before serving to help it set and slice cleanly.
