How to Make Breakfast Sausage Hash Browns Casserole Recipe
Step 1: Get the Oven and Pan Ready
Start by preparing your workspace: coat a 9×13 casserole dish with non-stick cooking spray to prevent sticking and preheat your oven to 350°F. This ensures your dish bakes evenly and comes out perfectly golden and firm.
Step 2: Cook the Sausage and Veggies
Heat a 10-inch non-stick skillet over medium-high heat, then add the ground pork sausage, diced red bell pepper, diced yellow onion, salt, and black pepper. Cook, stirring occasionally, until the sausage is browned all the way through and the vegetables have softened. This mixture develops the rich, savory base that flavors the entire casserole.
Step 3: Transfer the Sausage Mixture
Once cooked, drain any excess fat and transfer the sausage and vegetable blend into the prepared casserole dish. Getting rid of excess grease guarantees that the casserole won’t become overly oily and keeps every bite balanced.
Step 4: Layer the Hash Browns and Cheese
Sprinkle the frozen hash browns evenly over the sausage layer — this adds that classic crispy texture. Follow with a generous layer of shredded cheddar cheese. The cheese melts throughout baking, adding creamy richness and that irresistible golden crust on top.
Step 5: Whisk Together the Egg Mixture
In a medium bowl, whisk together the eggs and whole milk until completely combined. Pour this custardy mixture over the casserole layers in the dish, gently pressing down so everything melds together and soaks up the eggs, which will bind the casserole beautifully as it bakes.
Step 6: Cover and Bake
Cover the casserole with foil and pop it into the oven. Bake for 40 to 45 minutes, allowing the eggs to set and the flavors to marry. The foil keeps the moisture locked in so the casserole remains tender inside.
Step 7: Uncover and Finish Baking
Remove the foil and continue baking for an additional 10 minutes. This step lets the top develop a slight golden brown crust and the edges start to pull away from the pan, signaling that your breakfast masterpiece is done.
Step 8: Serve and Enjoy
Once out of the oven, slice into hearty portions and garnish with fresh green onions or your favorite herbs for a pop of color and fresh flavor. Serve warm and enjoy the bursting flavors in every forkful of this Breakfast Sausage Hash Browns Casserole Recipe.
How to Serve Breakfast Sausage Hash Browns Casserole Recipe

Garnishes
A sprinkle of thinly sliced green onions or freshly chopped parsley adds brightness and contrast to the dish’s rich, savory layers. You can also add a spoonful of sour cream or a few slices of ripe avocado for extra creaminess and texture.
Side Dishes
This casserole pairs beautifully with fresh fruit salad or a light green salad dressed in a simple vinaigrette to balance the richness. For a more indulgent brunch, crispy bacon or buttered toast on the side complements the meal perfectly.
Creative Ways to Present
Try portioning the casserole into individual ramekins for a charming brunch presentation or bake it in muffin tins for grab-and-go breakfast bites. For a festive twist, top each serving with a drizzle of hot sauce or a dollop of salsa to add a splash of color and a punch of flavor.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover casserole tightly with plastic wrap or store in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making leftovers even more delicious.
Freezing
If you want to save some for later, freeze the casserole in a sealed container for up to 2 months. Thaw overnight in the fridge before reheating to maintain texture and flavor.
Reheating
Reheat individual portions in the microwave for 1-2 minutes or warm the entire dish covered with foil in a 325°F oven until heated through. This will keep the casserole moist and give it a freshly baked feel.
FAQs
Can I use a different type of sausage?
Absolutely! You can swap pork sausage for turkey sausage, chicken sausage, or even a plant-based sausage to suit your preferences. Just be mindful of the seasoning and moisture content as it may slightly alter the final taste and texture.
Do I need to thaw the hash browns before using?
No need! Using frozen hash browns straight from the bag works perfectly. They bake right into the casserole, providing that lovely crispy bite without extra prep.
What can I use instead of whole milk?
You can substitute with 2% or skim milk, but whole milk helps make the eggs extra creamy and tender. For a richer flavor, half-and-half or cream works well, too, but expect a denser casserole.
Can I add vegetables to this recipe?
Yes! Feel free to add mushrooms, spinach, or zucchini to sneak in extra veggies. Sauté them along with the bell peppers and onions to soften before mixing into the casserole.
Is this recipe good for meal prepping?
Definitely! This Breakfast Sausage Hash Browns Casserole Recipe holds up well for breakfasts throughout the week. It’s easy to portion out and reheat for a quick, satisfying start to busy mornings.

Instructions
- Preparation: Prepare a 9×13 casserole dish by spraying it with non-stick cooking spray. Preheat your oven to 350°F (175°C) to get it ready for baking.
- Cook Sausage and Vegetables: Heat a 10-inch non-stick skillet over medium-high heat. Add the ground pork sausage, diced red bell pepper, diced yellow onion, salt, and black pepper.
