Loaded breakfast casserole stacks ten hash brown patties with sausage, ham, bacon, seasoned eggs, mozzarella, and sharp cheddar. The frozen patties form a convenient potato base, while three cooked breakfast meats make the 9-by-13-inch dish substantial enough for a crowd.
The recipe yields 15 servings and can be assembled in about 15 minutes. It bakes covered for 30 minutes, then receives its cheese topping and finishes uncovered until the eggs are set and the surface is golden.
Ingredients for Loaded Breakfast Casserole
Use 10 frozen hash brown patties, 1 pound cooked crumbled and drained breakfast sausage, 8 ounces chopped deli ham, 1 pound cooked crumbled bacon, 12 eggs, and 1 cup milk. Prepackaged cubed ham can replace chopped deli slices.
The topping needs 1/2 cup shredded mozzarella and 1 1/2 cups shredded sharp cheddar. Season the eggs with 1 tablespoon each garlic powder, onion powder, and black pepper; 1 optional tablespoon Cajun seasoning; and 1/2 teaspoon salt.

How to Make Loaded Breakfast Casserole
- Prepare the oven and dish. Heat the oven to 400°F and grease a 9-by-13-inch baking dish.
- Arrange the potatoes. Place all 10 frozen hash brown patties in a single layer across the base. They may go into the oven briefly while the other ingredients are prepared, but this is optional.
- Add the meats. Spread cooked drained sausage, chopped ham, and crumbled cooked bacon evenly over the patties.
- Mix the eggs. Whisk 12 eggs with 1 cup milk, garlic powder, onion powder, pepper, optional Cajun seasoning, and salt.
- Pour and cover. Pour the egg mixture evenly over the meat and potatoes. Cover the dish tightly with foil.
- Bake. Bake covered for 30 minutes.
- Add cheese and finish. Remove the foil, scatter mozzarella and cheddar over the top, and bake uncovered for 15 to 20 minutes more until the eggs are set and cheese is melted and golden.
- Rest and cut. Cool for several minutes before dividing into 15 portions.

Keep the Hash Brown Patties Frozen
The patties can go directly from freezer to greased dish, so no thawing or grating is required. Arrange them in one level layer; the final pieces may need to be turned or placed against the short end to cover the base efficiently.
For a firmer potato layer, put the patties in the preheating oven while the meats and eggs are organized. This step is optional and should not fully brown them before assembly.

Use Fully Cooked, Well-Drained Meat
Cook the sausage and bacon before they enter the casserole, then remove rendered grease. The oven time sets the eggs and heats the layers but is not intended to cook raw breakfast meat safely.
Chop the ham into small pieces similar in size to the sausage crumbles. Even pieces distribute throughout all 15 portions and allow the egg mixture to flow between them.
Whisk Twelve Eggs Thoroughly
Use a bowl large enough for 12 eggs and 1 cup milk. Whisk until the whites and yolks are completely combined, then mix in the dry seasonings so no concentrated pockets remain.
Pour slowly over the entire surface, moving from corner to corner. The liquid should settle around the meats and reach the hash brown base rather than collecting only in the center.
Cover the First Stage Tightly
Foil holds steady heat and moisture around the deep egg layer during the first 30 minutes. Crimp it around the edges of the baking dish so the center receives enough heat without the exposed edges drying.
Remove the foil carefully and check the center. It can still be soft at this stage because the casserole has another 15 to 20 minutes to bake after the cheese is added.
Add Cheese for the Uncovered Finish
Scatter 1/2 cup mozzarella and 1 1/2 cups sharp cheddar evenly after the foil comes off. Mozzarella supplies a soft melt, while sharp cheddar gives the top stronger flavor and color.
Return the uncovered dish to the 400°F oven. It is ready when the center is set, the cheese is bubbling, and the edges are golden. If the cheese colors too quickly, lay the foil loosely over the surface.
Rest and Portion for a Crowd
Let the casserole cool for several minutes so the egg structure settles around the meat and potatoes. For 15 servings, cut three rows across the short side and five along the long side.
Serve with fruit, sliced tomato, or a lightly dressed salad. Hot sauce works well at the table; keeping it optional lets guests control the heat if the Cajun seasoning is already present.
Practical Variations
Use only bacon or only sausage if that is what is available, maintaining roughly the same overall amount of cooked meat. Colby Jack, pepper jack, or a mild melting blend can replace some cheddar.
For less heat, omit the Cajun seasoning. Do not reduce the egg and milk quantities unless the baking dish and amount of filling are also adjusted, because the liquid binds all ten patties and the heavy meat layer.
Troubleshooting
- Center remains wet: Continue the uncovered bake in 5-minute intervals.
- Casserole is greasy: Drain sausage and bacon completely before layering.
- Edges are dry: Seal the foil tightly for the first 30 minutes.
- Seasoning tastes too salty: Use unsalted or lower-sodium meats and reduce added salt.
- Pieces do not hold: Let the casserole rest before cutting.
Make Ahead and Storage
The dish can be assembled the night before, covered, and refrigerated. Because it begins cold, add 10 to 15 minutes to the covered baking stage and confirm the center is set before serving.
Refrigerate cooled leftovers airtight for up to 3 days. Reheat individual portions in the microwave or warm several servings, covered, in the oven. Add a few uncovered minutes at the end if the cheese surface needs refreshing.
Conclusion
Arrange 10 frozen hash brown patties in a greased 9-by-13-inch dish. Layer on cooked drained sausage, ham, and bacon. Whisk 12 eggs with 1 cup milk and seasonings and pour over the layers. Cover and bake at 400°F for 30 minutes, add mozzarella and cheddar, then bake uncovered for 15 to 20 minutes until set.
Frequently Asked Questions

No. Arrange all 10 patties in the dish directly from frozen; a brief optional prebake can make the base firmer.
- → Do the sausage and bacon need to be cooked first?
Yes. Both must be fully cooked and thoroughly drained before they are layered into the casserole.
- → Can loaded breakfast casserole be made the night before?
Yes. Assemble, cover, and refrigerate it, then add 10 to 15 minutes to the covered bake because the dish starts cold.
- → How long does leftover breakfast casserole keep?
Store it airtight in the refrigerator for up to 3 days and reheat until steaming hot.
