This casserole draws inspiration from traditional Amish cooking, where simplicity and substance reign supreme. The layers build flavor and texture: crispy-edged hash browns form the base, followed by browned breakfast sausage that adds savory depth, then sautéed onions and bell peppers for sweetness and color. A generous blanket of cheddar and mozzarella creates that irresistible cheesy pull, while the egg and milk custard seeps through every layer, binding everything into a cohesive, comforting whole. After its overnight rest, the casserole emerges from the oven with a lightly golden top and a perfectly set center—ready to be sliced into generous portions that satisfy even the heartiest appetites.

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: Cook the sausage

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: Sauté the vegetables

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

Step 3: Layer the hash browns

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

Step 4: Add sausage and vegetables

Top with cooked sausage, then the sautéed vegetables.

Step 5: Add the cheese

Sprinkle cheddar and mozzarella cheeses evenly over the top.

Step 6: Prepare the egg mixture

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

Step 7: Pour over the casserole

Pour the egg mixture evenly over the casserole.

Step 8: Refrigerate overnight

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

Step 9: Prepare for baking

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

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

Step 11: Serve

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

Zusatztipps für die Zubereitung

The key to a perfect casserole is ensuring your hash browns are fully thawed before assembling. Excess moisture can lead to a watery final dish, so pat them dry with paper towels if needed. When browning the sausage, aim for good caramelization—it adds depth of flavor. Don't skip the step of letting the assembled casserole stand at room temperature before baking; this helps it cook more evenly. If the top is browning too quickly during baking, tent it loosely with foil for the final 15–20 minutes. The casserole is done when the center is set and doesn't jiggle when gently shaken, and a knife inserted in the middle comes out clean.

Varianten und Anpassungen

This recipe is wonderfully adaptable to your preferences and dietary needs. For a vegetarian version, simply omit the sausage or substitute with a plant-based breakfast sausage. You can boost the vegetable content by adding sautéed mushrooms, fresh spinach, or diced tomatoes. Swap the cheddar and mozzarella for pepper jack, gouda, or Swiss cheese for a different flavor profile. If you're avoiding gluten, ensure your sausage and hash browns are certified gluten-free. For a lighter version, use turkey sausage, reduce the cheese by half, and substitute whole milk with 2% or a dairy-free alternative. You can also prepare individual portions in ramekins or muffin tins for easy serving and portion control.

Serviervorschläge

This hearty casserole shines as the centerpiece of any breakfast or brunch spread. Serve it alongside fresh fruit salad, crispy bacon strips, or buttery toast for a complete meal. A dollop of sour cream, salsa, or hot sauce on each slice adds brightness and a personalized kick. For a sweeter contrast, pair it with cinnamon rolls or fruit muffins. Fresh orange juice, coffee, or mimosas make excellent beverage companions. The casserole also works beautifully as part of a buffet—it holds its shape well when sliced and stays warm for extended periods. Leftovers reheat wonderfully in the microwave or oven, making it an excellent option for meal prep throughout the week.
