Step-by-Step Instructions
Step 1: Prep the Slow Cooker
Spray the inside of your crock pot generously with nonstick cooking spray. This helps prevent sticking and makes cleanup easy.
Step 2: Cook the Meat
In a skillet:
-
Cook sausage or bacon until fully done
-
Drain excess grease
-
Set aside to cool slightly
This step is important to prevent excess oil in the casserole.
Step 3: Layer the Ingredients
In the crock pot, layer as follows:
-
Half of the hash browns
-
Half of the cooked meat
-
Half of the cheese
-
Optional vegetables
Repeat the layers once more.
Step 4: Mix the Egg Custard
In a large bowl, whisk together:
-
Eggs
-
Milk
-
Salt, pepper, garlic powder, and onion powder
Pour the egg mixture evenly over the layers in the crock pot.
Step 5: Slow Cook Overnight
Cover and cook:
-
LOW for 7–8 hours
or -
LOW for 6 hours, then switch to WARM
Do not open the lid while cooking—this keeps the temperature consistent.
Step 6: Wake Up to Breakfast!
In the morning, give the casserole a gentle stir, let it rest for 10 minutes, then serve warm.
