Ingredients
- breakfast sausage: Crumbled and browned for savory flavor.
- yellow onion: Diced for sweetness and aroma.
- large eggs: Whisked to bind the filling.
- whole milk: Creates a tender egg texture.
- frozen shredded hash browns: Adds potato layers and crisp edges.
- sharp cheddar: Adds melted cheese flavor.
Tools You’ll Need
- 9×13 baking dish: Holds the casserole evenly and prevents thin edges from drying.
Instructions
Step 1: Brown sausage and onion
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.
Tip: Drain extra grease after cooking.
Step 2: Mix filling ingredients
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.
Tip: Let frozen hash browns sit 10 minutes.
Step 3: Layer casserole filling
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.
Tip: Grease the dish with butter before filling.
Step 4: Bake until golden
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.
Tip: Rest 10 minutes before slicing.
Step 5: Slice and serve
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.
Tip: Add fresh herbs before serving.
Pro Tips
- Bake at 375°F for even texture.
- Use freshly shredded cheddar for better melting.
- Rest 10 minutes before cutting.
- Avoid extra milk to prevent watery filling.
- Choose dry frozen hash browns.
- Add paprika for extra flavor.
- Add bacon for a smoky twist.
- Use vegetables for a vegetarian version.
- Add jalapeño for spice.
Storage Instructions
