Ingredients Equipment Method Notes

Ingredients
  

Hash browns layer
  • 4 cup frozen hash browns thawed
Egg layer
  • 8 large eggs scrambled soft
  • 0.5 tsp milk
Sausage and cheese
  • 1 lb breakfast sausage cooked and crumbled
  • 2 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
Seasoning
  • 0.25 tsp Salt and pepper to taste
Finish
  • 2 green onions sliced

Equipment

  • 1 sheet pan

Method
 

Build the first hash brown layer
  1. Press half the hash browns into a greased baking dish as the first layer, spreading into an even, compact layer so it bakes cohesively.
  2. Layer half the scrambled eggs, cooked and crumbled sausage, and both cheeses over the hash browns in an even distribution, letting the cheese settle between the layers.
Add second layer and season
  1. Repeat with a second layer of hash browns, then add the remaining scrambled eggs, sausage, and cheeses so the bake has two distinct strata.
  2. Whisk milk with salt and pepper and pour evenly over the top, ensuring the liquid reaches the edges for consistent setting.
Bake and serve
  1. Bake at 375°F for 35-40 minutes until golden and set, and look for bubbling cheese and firm layers when you gently check the center.
  2. Top with sliced green onions before serving for a fresh finish and a pop of color across the top slice.

Notes

For the best texture, squeeze excess moisture from thawed hash browns before layering so the casserole doesn’t turn watery. Refrigerate leftovers in a covered container for up to 3 days; reheat individual portions in the microwave. Freezing is not recommended due to hash brown texture changes, but you can prep the layers (without baking) and bake within 24 hours. For a lighter option, use reduced-fat cheddar and mozzarella while keeping the bake time the same.
