- 1 teaspoon salt: Enhances all the savory notes to bring out the best in each ingredient.
- ½ teaspoon garlic powder: Provides a gentle depth of flavor without overpowering the dish.
- 20 oz frozen shredded hashbrowns, thawed: Bring that irresistible golden crispiness and texture to the casserole.
- 1 pound breakfast sausage: Cooked and drained, offering hearty, juicy, and smoky bursts throughout.

How to Make Hashbrown Breakfast Casserole with Sausage and Cheddar Recipe
Step 1: Whisk Together the Egg Mixture
Start by preheating your oven to 375°F and giving your 9×13 inch baking dish a light grease. In a large bowl, whisk the eggs, half and half, dijon mustard, salt, and garlic powder until beautifully combined. This mixture is the flavorful custard that will tie the casserole together with a tender, moist texture.
Step 2: Combine Hashbrowns, Sausage, and Cheese
Next, stir in the thawed hashbrowns, the cooked and drained breakfast sausage, and half of the shredded cheddar cheese (about ¾ cup). Mixing these ingredients thoroughly into the egg mixture ensures every bite will be packed with that classic sausage-cheddar-hashbrown goodness.
Step 3: Pour Into the Baking Dish
Carefully pour the entire mixture into the prepared baking dish, smoothing out the top so it bakes evenly. This step helps the casserole set perfectly in the oven, ensuring it cooks uniformly from edge to center.
Step 4: Add the Cheese Topping
Sprinkle the remaining cheddar cheese evenly across the top of your casserole. This will create a gorgeous golden crust once baked, adding a delightful visual and flavorful finish.
Step 5: Bake Covered Then Uncovered
Cover the dish with aluminum foil and bake for 30 minutes. After that, remove the foil and bake for an additional 10 to 15 minutes until the center is set and the cheese topping is lightly golden and bubbly. This two-stage bake locks in moisture and guarantees a crispy, cheesy top.
Step 6: Rest Before Serving
Once out of the oven, let the casserole rest for 10 to 15 minutes. This pause lets everything settle, making it easier to cut clean, attractive slices and allowing the flavors to meld even more deliciously.
Step 7: Garnish and Enjoy
Before serving, sprinkle chopped parsley or sliced green onions over the top for a burst of fresh color and a touch of brightness. This final step lifts the casserole, making it as pretty as it is tasty.
How to Serve Hashbrown Breakfast Casserole with Sausage and Cheddar Recipe

Garnishes
Fresh garnishes like chopped parsley or green onions add just the right pop of color and a slight crunch that cuts through the richness of the casserole. You can also try thinly sliced radishes or a dusting of smoked paprika for an extra flavor twist that impresses every time.
Side Dishes
This casserole pairs beautifully with simple sides such as fresh fruit salad for a sweet contrast or a crisp green salad dressed lightly with lemon vinaigrette. A side of buttery toast or warm biscuits also complements the hearty, cheesy flavors perfectly.
Creative Ways to Present
For brunch parties, consider preparing the casserole in mini muffin tins for individual servings that look adorable and save time. Alternatively, serve slices with dollops of sour cream or a drizzle of hot sauce for a casual flair that wows your guests effortlessly.
Make Ahead and Storage
Storing Leftovers
Leftover casserole is a gift that keeps on giving! Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. It reheats wonderfully and retains most of its original texture and flavor, making for a perfect quick breakfast or snack.
Freezing
If you want to make this casserole well in advance, you can freeze it either before baking or after. Wrap it tightly in foil and plastic wrap, then place it in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
To reheat, warm your portion in a 350°F oven for about 15-20 minutes or until heated through. Alternatively, the microwave works in a pinch, but the oven helps maintain that lovely crispy top and texture.
FAQs
Can I use a different type of cheese?
Absolutely! While cheddar gives a classic flavor, feel free to swap in mozzarella for a milder taste or pepper jack if you want a spicy kick in your Hashbrown Breakfast Casserole with Sausage and Cheddar Recipe.
Is it necessary to pre-cook the sausage?
Yes, cooking the sausage beforehand is important to release excess fat and ensure it’s fully cooked. This step helps avoid a greasy casserole and gives the sausage its best texture and flavor.
Can I add vegetables to this casserole?
Definitely! Sautéed onions, bell peppers, or mushrooms make great additions. Just cook them until tender first, and fold them into the mix for extra nutrition and color.
What if I don’t have half and half?
You can substitute whole milk or heavy cream depending on what you have. Whole milk will make it lighter, while heavy cream will give an even richer texture.
How do I make this recipe gluten-free?
This recipe is naturally gluten-free as long as your sausage doesn’t contain gluten fillers. Always check the sausage label to be sure, and enjoy without worry!
Final Thoughts
I can’t recommend the Hashbrown Breakfast Casserole with Sausage and Cheddar Recipe enough for those mornings when you want comfort, ease, and a crowd-pleasing dish all at once.
