This hash brown breakfast casserole packs crisp bacon, onions, two cheeses, and tender potatoes into one pan that feeds a crowd. Cottage cheese keeps the eggs creamy, and the top bakes into a golden, cheesy crust.
You can assemble it the night before and bake it in the morning, which makes it ideal for brunch, weekend guests, and busy mornings. The slices hold their shape, so it is simple to serve straight from the pan.

Why This Hash Brown Breakfast Casserole Recipe Works
Cottage cheese melts into the egg base and adds protein and body, so each slice stays moist instead of rubbery.
Thawed hash browns soak up the egg mixture and bake into a soft base with crisp, golden edges.
Cheddar and Swiss bring sharp and nutty flavors, while crumbled bacon adds a salty, savory bite.
Ingredients for Hash Brown Breakfast Casserole
- 1 pound diced bacon
- 1 medium onion, diced
- 8 large eggs
- 1/4 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon hot sauce, optional
- 4 cups frozen shredded hash browns, thawed
- 8 ounces shredded sharp cheddar cheese
- 6 ounces shredded Swiss cheese or Gruyere
- 16 ounces small curd cottage cheese
- 2 tablespoons chopped fresh chives, for garnish
Bacon. Cook the diced bacon until crisp and drain it well, since extra grease makes the pan heavy and wet.
Hash browns. Thaw the potatoes completely and squeeze out extra water in a towel so the bake sets firmly.
Cheeses. Shred cheddar and Swiss from blocks, because they melt more smoothly than bagged shreds.
Cottage cheese. Small curd blends in more evenly than large curd, and either full fat or low fat works.
Salt. The bacon and cheeses already add plenty of salt, so the recipe uses only a small amount.
How to Make Hash Brown Breakfast Casserole
1. Heat and grease Heat the oven to 350 degrees F and grease a 9 by 13 inch baking dish.
2. Cook the bacon Cook the diced bacon in a large skillet over medium heat until crisp, then add the onion and cook until soft.
3. Drain the mixture Lift the bacon and onion onto paper towels and let them drain for two minutes.
4. Whisk the eggs Whisk the eggs with the salt, pepper, and hot sauce in a large bowl until no streaks remain.
5. Combine everything Stir in the hash browns, both cheeses, cottage cheese, bacon, and onion until evenly mixed.
6. Bake until set Pour into the dish, spread it level, and bake for 35 to 45 minutes until the center reaches 160 degrees F.
7. Rest and slice Rest the pan for five to ten minutes so the eggs set, then cut into squares and top with chives.
How to Serve Hash Brown Breakfast Casserole
Serve squares warm with fresh fruit, or set out muffin tin egg bites and cinnamon roll pancakes for a bigger brunch spread. A glass of banana blueberry smoothie suits kids and adults, and a slice of cinnamon streusel coffee cake finishes the table.
How to Store and Reheat Hash Brown Breakfast Casserole
Cool leftovers within two hours, then cover and refrigerate for three to four days. Reheat individual portions in the microwave or oven until they reach 165 degrees F. For longer storage, wrap squares tightly and freeze for up to three months, then thaw overnight in the refrigerator.
Tips and Variations for Hash Brown Breakfast Casserole
Flag the allergens. This dish contains egg, milk, and pork, and some hot sauces and bacon cures contain other additives, so check labels for guests.
Bake it fully. Cook until the center reaches 160 degrees F, because the egg mixture must be fully set before you serve it.
Make it ahead. Assemble the pan, cover tightly, and refrigerate overnight, then add five to ten minutes to the bake time.
Thaw the potatoes safely. Thaw hash browns in the refrigerator overnight rather than on the counter to keep them out of the danger zone.
Swap the meat. Use ham or cooked sausage for the bacon, and make sure sausage reaches 160 degrees F before it goes in the pan.
Add vegetables. Fold in sauteed peppers or spinach, and squeeze spinach dry so the dish does not turn watery.
Add heat. Stir in diced jalapeno and wear gloves while you chop it to avoid skin irritation.
