What Makes This Recipe So Good

Perfect for busy mornings because you can prepare it the night before and let it cook while you sleep. It’s hearty, full of protein, and customizable with your favorite ingredients. Plus, using a slow cooker means less time in the kitchen and more time enjoying your breakfast.

Kitchen Advice

- Grease the slow cooker well to prevent sticking and make cleanup easier.
- Avoid lifting the lid frequently while cooking to keep the temperature consistent.
- Use day-old bread for better texture, as it absorbs the eggs without becoming mushy.

Directions

Lin your slow cooker with a liner and give it a quick spray with cooking spray to keep things from sticking. Next, heat up a large skillet over medium-high heat and cook the sausage, breaking it up as it browns, until it’s nice and crumbly—this usually takes about 5 to 7 minutes. Drain off any grease and set the sausage aside. In a bowl, whisk together the eggs, milk, dry mustard, garlic powder, onion powder, salt, and pepper until everything is well combined. Now, layer a third of the hash browns, then a third of the cooked sausage, and a third of the shredded cheddar cheese in the bottom of the slow cooker. Repeat these layers two more times, finishing with cheese on top. Pour the egg mixture evenly over everything. Cover and cook on low for 6 to 8 hours, or until the eggs are fully set and ready to enjoy.

Creative Serving Ideas

Serve warm with a side of fresh fruit or a simple green salad for a balanced meal. Adding a dollop of sour cream or a sprinkle of fresh herbs like chives or parsley can brighten up the flavors. It also pairs nicely with a cup of coffee or freshly squeezed juice.

How To Save Leftovers

Let the casserole cool completely before storing it in an airtight container. It can be kept in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven until warmed through. For longer storage, freeze portions wrapped tightly in foil or plastic wrap for up to 2 months.
