Place a crockpot liner in your crockpot and spray the liner with nonstick cooking spray. If no liner, you can just spray the crockpot with the nonstick cooking spray.

*Don't cook the breakfast casserole without spraying the nonstick cooking spray, even if you have a liner in the crockpot.

Cook the breakfast sausage over medium heat, crumbling as it cooks, while preparing the rest of the casserole.

Put 3-4 cups of frozen hash-brown on the bottom of the crockpot. This will create the bottom layer.

When the sausage is done cooking, place all of the sausage over the hash-brown layer in the crockpot. This will create the second layer.

Add the diced peppers and onions on top of the sausage.

In a separate bowl, crack 16 large eggs and add the milk (if you choose), and the cayenne pepper. Whisk together until the eggs are completely beaten. Pour the egg mixture over the top of the other layers and top with cheese.

Cook on high for 4 hours or low for 8 hours. Serve and enjoy!
