Step‑by‑Step Instructions for Sausage Hash Brown Breakfast Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 190°C (375°F). While it warms up, grab a 9×13-inch baking dish and generously grease it with oil or cooking spray to ensure easy serving after baking. Preheating is crucial, as it ensures your Sausage Hash Brown Breakfast Casserole bakes evenly and achieves that desired golden crust.
Step 2: Cook Sausage and Vegetables
In a large skillet over medium heat, add the sausage and cook until browned, about 5-7 minutes, breaking it apart with a spatula. Once fully browned, stir in the chopped onions and sauté until translucent, about 3-4 minutes. Add in the bell peppers, cooking for another 3-4 minutes until they soften. Set aside this delicious mixture to allow the flavors to meld beautifully.
Step 3: Prepare Potatoes
While the sausage and vegetables are cooling, take about 4 cups of thawed frozen hash browns and grate fresh potatoes using a box grater. There’s no need to peel them; just make sure to pat them dry with a clean kitchen towel to remove any excess moisture. This step is essential for a crispy bottom layer in your Sausage Hash Brown Breakfast Casserole.
Step 4: Mix Egg Custard
In a large bowl, whisk together 8 large eggs and 1 cup of heavy cream until fully combined. Season the mixture generously with salt and pepper to enhance the flavor of your casserole. This creamy custard will envelop all the ingredients, creating a rich, satisfying texture when baked, so take your time to ensure it’s well mixed.
Step 5: Layer Ingredients
Begin layering in the prepared baking dish by evenly spreading the grated potatoes as the first layer. Next, pour the sausage and veggie mixture over the potatoes, ensuring even distribution. Sprinkle about 1.5 cups of cheese over the sausage layer, reserving some for the topping. Finally, pour the egg custard mixture evenly over everything to bind the casserole.
Step 6: Bake
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 40 minutes to allow the casserole to set and cook through. After this time, carefully remove the foil and sprinkle the remaining cheese on top. Bake uncovered for an additional 15-20 minutes, until the cheese is bubbling and golden brown, and the casserole looks firm.
Step 7: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 10 minutes. This step is vital for achieving clean, perfect slices. As it cools slightly, the flavors continue to develop, and it’s easier to cut into squares without falling apart. Serve warm for a hearty breakfast that everyone will love!

Make Ahead Options
These Sausage Hash Brown Breakfast Casserole preparations are perfect for busy mornings, saving you time without sacrificing flavor! You can prepare the entire casserole up to 24 hours in advance by assembling all the layers in the baking dish and covering it tightly with plastic wrap. Simply refrigerate until you’re ready to bake. Alternatively, you can cook the sausage and vegetables and store them separately in the fridge for up to 3 days, which allows you to assemble the casserole quickly when you’re ready. To maintain quality, ensure the hash browns are patted dry before layering to avoid excess moisture. When you’re ready to serve, pop it in the oven as directed—your family will enjoy the same deliciousness, with minimal morning effort!

Sausage Hash Brown Breakfast Casserole Recipe FAQs
How do I select the right hash browns?
Absolutely! When choosing hash browns, look for frozen brands that are thawed and contain minimal additives. Make sure to pat them dry before use to avoid excess moisture, which can lead to a soggy casserole. If you prefer fresh potatoes, use 4 cups of grated scrubbed potatoes, being careful not to peel them to maintain texture.
What is the best way to store leftovers?
Very! Store any leftovers in an airtight container in the refrigerator for up to 4 days. This not only keeps your casserole fresh but also makes for a quick meal option on busy mornings! If you want to enjoy it later, wrap portions tightly in plastic wrap followed by aluminum foil and freeze them for up to 2 months.
Can I freeze the Sausage Hash Brown Breakfast Casserole?
Yes, indeed! To freeze, first cool the casserole completely after baking. Then, cut it into portions and wrap each one tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. When you’re ready to enjoy, simply thaw in the refrigerator overnight, then reheat in a 180°C (350°F) oven for about 20-25 minutes until heated through.
What if my casserole turns out soggy?
No problem! A common troubleshooting tip is to ensure all your vegetables (especially tomatoes) are cooked and drained of excess moisture before layering them in the casserole. Additionally, using well-thawed and patted dry frozen hash browns is crucial; otherwise, they can release water during baking. If you notice your casserole is too watery next time, remember to cut back on watery veggies or check for moisture issues.
Is this casserole suitable for dietary restrictions?
Absolutely! This casserole is quite versatile. For a vegetarian version, you can easily skip the sausage and increase the number of vegetables used—spinach, mushrooms, or zucchini make great substitutes. Be mindful of dietary allergies by checking the cheese and cream options—consider dairy-free alternatives if needed. Likewise, always confirm that any sausage variation you choose aligns with dietary preferences or restrictions.
How long should I let the casserole rest before serving?
Great question! Allow the casserole to rest for about 10 minutes after baking. This is crucial for helping the layers set and makes it easier to slice into neat squares. The resting time allows those beautiful flavors to further meld, resulting in a delightful serving experience.
