Ingredients
- 20 ounces Frozen shredded hash browns
- 8 ounces Breakfast sausage
- 8 Large eggs
- 1 cup Whole milk
- 2 cups Shredded sharp cheddar cheese
- 1 medium Red bell pepper
- 3 Green onions
- 1 teaspoon Garlic powder
- 1/2 teaspoon Salt
- 1/4 teaspoon Black pepper
- 1 tablespoon Unsalted butter
Instructions
- Begin by making sure the frozen hash browns are completely thawed and thoroughly drained. Gently squeeze out any excess moisture because watery potatoes can make the finished casserole too soft. Make sure the breakfast sausage is already fully cooked and crumbled before assembling the casserole.
Place the red bell pepper on a wooden cutting board and remove the stem and seeds before cutting the pepper into small irregular pieces. Slice the three green onions into thin rounds and separate the green tops for the finishing garnish. The colorful vegetables should remain in loose little piles with naturally uneven sizes.
- Crack all eight eggs into a large mixing bowl and add the whole milk. Sprinkle in the garlic powder and salt and black pepper before whisking until the yolks and whites are combined into a smooth pale yellow mixture.
The mixture should become slightly frothy around the edges while remaining thin enough to flow between the shredded potatoes later. Small bubbles and a few darker pepper specks should remain visible throughout the liquid.
- Preheat the oven to 375 degrees Fahrenheit and coat a 9 by 13 inch ceramic baking dish with the softened butter. Spread the thawed and well drained hash browns across the bottom of the dish and gently press them into a loose even layer without packing them tightly.
Scatter the cooked crumbled breakfast sausage over the potatoes and follow with the diced red bell pepper and the white portions of the green onions. Some pieces should settle between the shredded potatoes while others remain visible on top. The casserole should look naturally uneven with colorful ingredients distributed across the dish.
- Slowly pour the whisked egg and milk mixture over the layered hash browns and sausage. Move the pour across different sections of the baking dish so the liquid can flow between the potato shreds and around the vegetables. Gently shift any exposed potatoes that remain completely dry so they make contact with the egg mixture.
Scatter two cups of shredded sharp cheddar cheese across the top and allow some potato shreds and red pepper pieces to remain visible. The uncooked casserole should have a pale yellow filling beneath an uneven blanket of orange cheese with small pockets of sausage and vegetables showing through.
- Place the assembled casserole in the preheated oven and bake uncovered for approximately 40 to 45 minutes. As the casserole cooks the egg mixture gradually firms around the potatoes while the cheddar melts into the surface and the edges begin turning lightly golden brown.
Continue baking until the center is set and a thermometer inserted into the egg filling reaches 160 degrees Fahrenheit. The cheese should have irregular golden patches and the potato edges should look lightly crisp. Remove the casserole from the oven and allow it to rest for about 5 minutes so the filling settles before slicing.
- After the casserole has rested use a spatula to divide it into eight generous portions. Carefully transfer one square portion onto a white serving plate while keeping the golden cheesy top visible. The cut edges should reveal tender shredded potatoes and fluffy cooked eggs with small pieces of sausage and bell pepper tucked throughout.
Scatter a small amount of the reserved green onion tops over the warm serving. Allow a few shreds of potato and small crumbs to fall naturally beside the slice while the melted cheese remains soft and slightly uneven. Serve immediately while the inside is warm and the edges still have a little crisp texture.
Notes
Pro Tips:
- Thaw the hash browns completely and squeeze out extra moisture before baking so the casserole holds together without becoming watery.
- Use freshly shredded sharp cheddar when possible because it melts smoothly and creates a rich topping with naturally golden edges.
- Choose fully cooked and well drained breakfast sausage so the casserole stays flavorful without collecting excess grease during baking.
- Let the finished casserole rest for about five minutes before slicing because the egg filling firms slightly and portions hold together better.
Storage: Refrigeration: Allow the Hash Brown Breakfast Casserole to cool slightly after baking and transfer leftovers into airtight containers within two hours. Refrigerate promptly and keep at 40 degrees Fahrenheit or below for up to three to four days. Store individual portions separately when possible so you can reheat only the amount needed for breakfast.
Freezing: Allow the casserole to cool before dividing it into individual servings. Wrap each portion tightly and place the wrapped slices inside freezer safe containers or bags. Freeze for up to two months for the best texture and label each package with the preparation date so it is easy to keep track of leftovers.
Reheating: Reheat refrigerated portions in the microwave until steaming hot and the center reaches 165 degrees Fahrenheit. For a slightly crispier texture place a portion in an oven safe dish and warm at 350 degrees Fahrenheit until heated completely through. Cover loosely if the cheese begins to brown too much before the center becomes hot.
Make Ahead Preparation: Assemble the casserole in the baking dish without baking and cover tightly before placing it in the refrigerator overnight. Keep the assembled casserole refrigerated for no more than 24 hours before baking. When ready to cook remove it from the refrigerator while the oven preheats and bake until the eggs are fully set and the center reaches 160 degrees Fahrenheit. A chilled casserole may need a few additional minutes in the oven.
