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: Prepare the Baking Dish

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

Step 4: Layer the 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: Preheat and Rest

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: Cool and Garnish

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

Zusatztipps für die Zubereitung

Make sure your hash browns are fully thawed before assembling the casserole—excess moisture can lead to a watery dish. Pat them dry with paper towels if needed. When browning the sausage, aim for good caramelization; those browned bits add incredible flavor. If you're short on time in the evening, you can prep the sausage and vegetables earlier in the day and refrigerate them separately until assembly. Don't skip the 15-minute rest at room temperature before baking—it helps the casserole cook more evenly.

Varianten und Anpassungen

For a vegetarian version, omit the sausage or substitute with vegetarian sausage crumbles. You can add mushrooms, spinach, or even diced tomatoes for extra vegetables and nutrition. Swap cheddar for pepper jack cheese if you prefer a spicy kick, or use Swiss cheese for a milder flavor. Turkey sausage works beautifully as a leaner alternative to pork. If you're dairy-sensitive, use plant-based milk and cheese, though the texture may vary slightly. For a gluten-free version, double-check that your sausage and hash browns are certified gluten-free.

Serviervorschläge

Serve this casserole hot from the oven with a side of fresh fruit salad, buttered toast, or biscuits. It pairs wonderfully with salsa, hot sauce, or a dollop of sour cream for those who like extra creaminess. A simple green salad with a tangy vinaigrette balances the richness beautifully. For a complete brunch spread, add a platter of fresh pastries and a pitcher of fresh-squeezed orange juice or coffee. Leftovers reheat wonderfully—just cover and microwave individual portions for 1–2 minutes, or reheat covered in a 300°F oven for 15–20 minutes.
