½ red bell pepper (cored and diced): Offers sweetness and vibrant red color for visual appeal.

Step 1: Prepare Your Oven and Dish

Preheat your oven to 350°F to ensure a perfect cooking temperature. Lightly spray a 13×9-inch casserole dish with non-stick spray to prevent sticking and make cleanup easier later on.

Step 2: Brown the Sausage

Heat a large skillet over medium heat and cook the ground Italian sausage. Use a wooden spoon to break it into small pieces as it cooks. Once browned and cooked through, drain the excess fat and set the sausage aside to cool slightly. This step infuses the casserole with deep, savory flavor and hearty texture.

Step 3: Whisk the Custard Base

In a large mixing bowl, whisk together the eggs, sour cream, whole milk, salt, and ground black pepper until smooth. This mixture acts as the creamy custard that binds all ingredients together and sets beautifully when baked.

Step 4: Combine Ingredients

Gently fold shredded cheddar cheese, sliced green onions, diced red and green bell peppers, cooked sausage, and thawed hash browns into the egg mixture. Stir until everything is evenly incorporated, ensuring each bite will be packed with flavor and texture.

Step 5: Bake to Perfection

Pour the entire mixture into your prepared casserole dish, spreading it evenly. Bake for 45 to 55 minutes, or until the hashbrowns have cooked through and the edges are set. The center should still be slightly jiggly—a sign it will firm up as it rests for a perfect custardy consistency.

Step 6: Rest and Serve

Remove the casserole from the oven and let it rest for about 5 minutes before slicing. This resting time helps the casserole set, making it easier to serve and enjoy every warm, cheesy bite.

Garnishes

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen after a night in the fridge, making the next-day breakfast even better.

Freezing

This Hashbrown Sausage Breakfast Casserole Recipe freezes wonderfully. Wrap in foil or place in a freezer-safe container and freeze for up to 2 months. Thaw overnight in the fridge before reheating to maintain the casserole’s creamy texture.

Reheating

Reheat leftover casserole in the oven at 350°F for about 15-20 minutes or until warmed through. You can also microwave individual portions, but watch for uneven heating to keep that perfect custard consistency.

FAQs

Can I use turkey sausage instead of Italian sausage?

Absolutely! Turkey sausage is a great leaner alternative and will still give you plenty of flavor and protein while reducing fat content.

Is it necessary to thaw the hash browns before baking?

Yes, thawing the hash browns ensures even cooking and prevents excess moisture from making the casserole soggy.

Can this casserole be made vegetarian?

Yes, simply omit the sausage and consider adding cooked mushrooms or a plant-based sausage substitute for extra heartiness.

What type of cheese works best in this recipe?

Sharp cheddar is ideal for its melting ability and bold flavor, but you can experiment with Monterey Jack, mozzarella, or a blend for a different twist.

How do I know when the casserole is fully cooked?

The edges should be set and golden, while the center remains slightly jiggly. A fork-tender hashbrown taste test is a great way to check doneness before removing from the oven.
