🛒 Ingredients

Here’s what you’ll need:

  • 1 (26–30 oz) bag frozen hash browns (shredded or diced)
  • 1 lb breakfast sausage (pork or turkey), cooked and crumbled
  • 1 medium onion, finely chopped
  • 2 cups shredded cheese (cheddar, Colby Jack, or your favorite blend)
  • 12 large eggs
  • 1 cup milk
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • Cooking spray or butter to grease the slow cooker

👩‍🍳 Directions

1. Cook the Sausage and Onion

In a skillet over medium heat, cook the sausage until browned and crumbly. Add chopped onion and cook until soft and translucent. Drain any excess grease.

2. Grease Your Slow Cooker

Spray the inside of your slow cooker generously with cooking spray or rub with butter to prevent sticking.

3. Layer the Ingredients

Start layering in this order:

  • ⅓ of the hash browns
  • ⅓ of the sausage/onion mixture
  • ⅓ of the cheese
    Repeat the layers two more times (hash browns, sausage, cheese).

4. Mix the Eggs

In a large bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until well combined.

5. Pour and Cook

Carefully pour the egg mixture over everything in the slow cooker, making sure it’s evenly distributed.

6. Slow Cook It

  • LOW: 7–8 hours
  • HIGH: 3½–4 hours
    It’s done when the eggs are set and the edges are golden brown.
