Ingredients You’ll Need
- 1 pound breakfast sausage, casings removed and crumbled
- Use pork, turkey, or plant-based sausage. Cook it fully and drain excess fat.
- 1 bag frozen shredded hash browns, 20 to 24 ounces, thawed and patted dry
- Ore-Ida or store brand both work. Use diced hash browns if you like chunkier texture.
- 8 large eggs
- 1 cup milk or half-and-half
- Whole milk keeps it light and creamy. Half-and-half yields a richer custard. Unsweetened almond milk works in a pinch.
- 1 cup shredded sharp cheddar cheese, plus 1/2 cup for topping
- 1/2 cup shredded mozzarella or pepper jack
- 1 small yellow onion, finely diced
- Shortcut: 1 teaspoon onion powder.
- 1 bell pepper, diced
- Any color works. Use a small can of green chiles for a Tex-Mex twist.
- 2 cloves garlic, minced
- Shortcut: 1 teaspoon garlic powder.
- 2 tablespoons melted butter or olive oil
- 1 teaspoon kosher salt, divided
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon crushed red pepper flakes, optional
- Optional toppings: sliced green onions, salsa, hot sauce, sour cream
Sub swaps and notes:
- Use 1 to 1 1/2 cups diced cooked ham or crisp bacon instead of sausage.
- Add 1 cup chopped spinach or mushrooms for extra veg. Sauté to remove moisture.
- Use Monterey Jack, Colby Jack, or a Mexican blend if cheddar runs low.
Equipment:
- 9×13-inch baking dish
- Large skillet
- Mixing bowl and whisk
- Spatula
- Foil
- Cooking spray or butter for the pan
How to Make Egg HashBrown Breakfast Casserole
- Prep: 15 minutes
- Cook: 45 minutes
- Total: 1 hour
- Heat the oven to 375°F. Grease a 9×13 baking dish with butter or spray.
- Brown the sausage in a skillet over medium heat, breaking it up as it cooks. Drain excess fat and set the sausage aside.
- In a mixing bowl, toss thawed hash browns with melted butter, 1/2 teaspoon salt, black pepper, and smoked paprika. Press the potatoes into the greased dish and bake for 10 minutes to jump-start browning.
- Sauté the diced onion and bell pepper in the same skillet until tender, about 4 to 5 minutes. Stir in the cooked sausage and crushed red pepper flakes if using.
- Whisk the eggs, milk, remaining 1/2 teaspoon salt, and garlic in a bowl until smooth and evenly mixed.
- Remove the par-baked hash browns from the oven. Scatter the sausage and veggie mixture over the potatoes, then sprinkle on the cheeses.
- Pour the egg mixture evenly over everything. Tilt the pan if needed to spread the liquid to the corners.
- Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake another 15 minutes, or until the center feels firm and a thermometer in the center hits 160°F.
- Let the casserole settle while you set the table. Top with green onions and slice into squares.
Tips & Tricks
- Dry the thawed hash browns with paper towels to boost crisp edges.
- Use half-and-half for a custard-like bite; use milk for a lighter texture.
- Spread the hash browns in an even, tight layer so the base browns instead of steaming.
- Grate cheese from a block to avoid clumping from anti-caking powders.
- Keep the egg mixture simple. Too many add-ins can crowd the pan and lengthen bake time.
- Test doneness with a gentle shake. The center should barely jiggle, not slosh.
- Want extra protein without more meat? Stir 1/2 cup small-curd cottage cheese into the eggs.
What to Serve with Egg HashBrown Breakfast Casserole
Serve this breakfast casserole with a bright fruit salad or sliced citrus to balance the richness. Add a simple arugula salad with lemon and olive oil for a fresh bite. Offer salsa, hot sauce, or avocado for customizable toppings, and pour hot coffee or orange juice to round out the spread.
Make-Ahead and Storage
Assemble the casserole the night before: build it through step 7, cover, and refrigerate. Add 5 to 10 minutes to the bake time if the dish goes in cold. For short-term storage, refrigerate leftovers in airtight containers for up to 4 days.
For freezing, wrap the unbaked assembled casserole tightly and freeze up to 2 months, or freeze baked squares for up to 3 months. Thaw in the fridge overnight. Reheat covered at 325°F until hot in the center, about 20 to 25 minutes for a full pan or 10 to 15 minutes for portions. You can also reheat single servings in the microwave on 50 percent power until warmed through.
