Ingredients
Scale
- 1 pound breakfast sausage (Crumbled and browned for savory flavor.)
- 1 medium yellow onion (Diced for sweetness and aroma.)
- 8 large large eggs (Whisked to bind the filling.)
- 2 cups whole milk (Creates a tender egg texture.)
- 30 ounces frozen shredded hash browns (Adds potato layers and crisp edges.)
- 2 cups sharp cheddar (Adds melted cheese flavor.)
Instructions
- Cook 1 pound breakfast sausage and 1 diced yellow onion at medium-high heat for 8 to 10 minutes. Break pieces apart and stir until golden. You’ll smell savory flavors. Watch the edges darken. Miss this and moisture remains. Browning builds deeper flavor.
- Whisk 8 eggs with 2 cups milk and fold in 30 ounces frozen shredded hash browns, sausage, onion and 2 cups sharp cheddar. Mix gently for 3 minutes. The filling looks creamy with visible potato strands. Avoid overmixing. Gentle folding keeps texture balanced.
- Spread filling into a 9×13 dish and bake at 375°F for 5 minutes to begin setting edges. Use a spatula to level the surface. The top stays soft while edges hold shape. Don’t rush. Even layers help the center cook properly.
- Bake at 375°F for 35 to 40 minutes until the center reaches 160°F. Rotate halfway and check firmness. (I tested 400°F first. The top set too fast.) Golden edges show the eggs have set.
- Rest for 10 minutes then cut one portion and place it on a plate. Show the layers and melted cheese inside. The slice holds together with tender filling. Skipping rest causes messy cuts. Resting keeps the layers stable.
Notes
Pro Tips:
- Bake at 375°F for even texture.
- Use freshly shredded cheddar for better melting.
- Rest 10 minutes before cutting.
