  • Author: BeauCollier

Description

This recipe is a true one-pot wonder that cooks while you sleep. Layers of fluffy eggs, crispy potatoes, savory sausage, and melted cheese come together into a cozy, crowd-pleasing breakfast that’ll have everyone asking for seconds. So plug in that slow cooker, set it before bed, and wake up to pure holiday happiness.


Ingredients

Scale

For the Casserole:

  • 24 large eggs

  • 2 cups whole milk (for richness)

  • 4 lbs frozen hash browns (shredded style, unthawed)

  • 2 lbs breakfast sausage, browned and crumbled

  • 1 cup diced onions

  • 1 cup diced red and green bell peppers

  • 2 cups shredded cheddar cheese

  • 2 cups shredded pepper jack cheese

  • 1½ tsp kosher salt

  • 1 tsp black pepper

  • 1 tsp smoked paprika (optional but magical)

  • 12 large croissants, torn into pieces (optional texture boost)

  • Butter or non-stick spray for greasing


Instructions

  1. Prep the Slow Cooker:
    Generously grease the inside of a 6–8 quart crockpot with butter or non-stick spray. Get every corner—this ensures easy cleanup later!

  2. Layer the Goodness:

    • Start with half the frozen hash browns.

    • Add half the sausage, onions, peppers, croissant pieces, and cheese.

    • Repeat the layers with the remaining ingredients.

  3. Whisk the Egg Mixture:
    In a large bowl, whisk together the eggs, milk, salt, pepper, and smoked paprika until smooth and airy. Pour evenly over the layered ingredients, letting it soak through the layers.

  4. Cook Overnight:

    • Cover and cook on LOW for 8 hours (perfect for overnight) or HIGH for 4 hours.

    • It’s ready when the eggs are set and the top is golden brown.

  5. Serve & Enjoy:
    Scoop generous portions into bowls, top with sour cream, chives, or a dash of hot sauce, and serve with fresh fruit or toast.

Notes

  • Make-Ahead: Assemble everything the night before, refrigerate, then start cooking before bed.

  • Cheese Matters: Shred your own cheese—it melts creamier than pre-shredded.

  • No Mushy Veggies: If using fresh peppers or mushrooms, lightly sauté them first to remove excess moisture.

  • Holiday Hero Move: Place a clean kitchen towel under the lid while cooking to absorb condensation and prevent soggy spots.
