The magic of this casserole begins with its foundation of thawed hash brown potatoes, which form a sturdy, comforting base. Browned breakfast sausage adds rich, savory depth, while sautéed onions and red and green bell peppers bring sweetness and a pop of color. A generous blend of cheddar and mozzarella cheeses melts into every layer, and the custard-like egg mixture, seasoned with garlic powder, smoked paprika, salt, and pepper, binds everything together as it bakes. After its overnight rest in the refrigerator, the casserole emerges from the oven golden and set, with edges that turn deliciously crispy and a center that stays tender and creamy. A sprinkle of fresh parsley or chives adds a bright finishing touch.

Ingredients

• 1½ pounds (680 g) breakfast sausage (pork or turkey), casings removed
• 1 medium onion, finely chopped
• 1 red bell pepper, diced
• 1 green bell pepper, diced
• 3 cups (400 g) frozen shredded hash brown potatoes, thawed
• 2 cups (225 g) shredded cheddar cheese
• 1 cup (115 g) shredded mozzarella cheese
• 2 cups (480 ml) whole milk
• 12 large eggs
• 1 teaspoon salt
• ½ teaspoon freshly ground black pepper
• ½ teaspoon garlic powder
• ½ teaspoon smoked paprika (optional)
• ¼ cup (10 g) chopped fresh parsley or chives (optional, for garnish)

Instructions

Step 1

In a large skillet over medium heat, cook the sausage, breaking it up with a spoon, until browned and cooked through, about 7–9 minutes. Remove sausage with a slotted spoon and set aside.

Step 2

In the same skillet, sauté the onion and bell peppers until softened, about 4–5 minutes. Remove from heat.

Step 3

Grease a 9x13-inch (23x33 cm) baking dish. Spread the thawed hash browns evenly in the bottom.

Step 4

Top with cooked sausage, then the sautéed vegetables.

Step 5

Sprinkle cheddar and mozzarella cheeses evenly over the top.

Step 6

In a large bowl, whisk together eggs, milk, salt, black pepper, garlic powder, and smoked paprika.

Step 7

Pour the egg mixture evenly over the casserole.

Step 8

Cover tightly with foil or plastic wrap and refrigerate overnight (at least 8 hours).

Step 9

In the morning, preheat the oven to 350°F (175°C). Remove casserole from fridge and let stand at room temperature for 15 minutes.

Step 10

Bake, uncovered, for 50–60 minutes, or until eggs are set in the center and the top is lightly golden.

Step 11

Cool 10 minutes before slicing. Garnish with fresh parsley or chives if desired.

Zusatztipps für die Zubereitung

Make sure your frozen hash browns are fully thawed before assembling the casserole to avoid excess moisture that can make the dish watery. You can thaw them overnight in the refrigerator or leave them at room temperature for a few hours. When browning the sausage, break it into small, bite-sized crumbles for even distribution throughout the casserole. Don't skip letting the assembled casserole sit at room temperature for 15 minutes before baking—this helps it cook more evenly. If the top is browning too quickly during baking, tent it loosely with foil for the remaining time.

Varianten und Anpassungen

For a vegetarian version, omit the breakfast sausage or substitute with a plant-based sausage alternative. You can also add extra vegetables like sliced mushrooms, fresh spinach, or diced zucchini for added nutrition and flavor. If you prefer a spicier kick, mix in diced jalapeños or serve with hot sauce on the side. For a lighter option, use turkey sausage, reduced-fat cheese, and low-fat milk. You can also experiment with different cheese combinations such as Monterey Jack, pepper jack, or Swiss.

Serviervorschläge

This casserole is a complete breakfast on its own, but it pairs beautifully with fresh fruit salad, sliced avocado, or a simple green salad for brunch. Serve with salsa, sour cream, or hot sauce on the side for guests to customize their plates. Toasted bread, biscuits, or croissants make excellent accompaniments for soaking up the rich, cheesy egg mixture. For a festive brunch spread, add a platter of bacon or sausage links, fresh orange juice, and coffee. Leftovers reheat wonderfully in the microwave or oven, making this dish perfect for meal prep throughout the week.
