- Potatoes (4 large, peeled and thinly sliced): Thin slicing ensures even cooking and a fluffy texture.
- Eggs (6 large): The binding agent that holds all the flavors together with a creamy consistency.
- Milk (1 cup): Adds moisture and richness without weighing down the casserole.
- Cheddar cheese (1 cup shredded): Sharp and melty, it adds an irresistible cheesy goodness.
- Onion (1/2 cup diced): Brings sweetness and depth to balance the richness.
- Cooked turkey or beef sausage (1/2 cup crumbled): Adds a savory punch and a bit of protein.
- Garlic powder (1/2 teaspoon): Offers a subtle aroma and depth without overpowering.
- Salt (1/2 teaspoon): Essential to enhance all the flavors.
- Black pepper (1/4 teaspoon): Adds a gentle heat and balances savory notes.
- Butter (1 tablespoon): Used to grease the baking dish, preventing sticking and adding richness.
How to Make Potato and Egg Casserole with Sausage and Cheddar Recipe
Step 1: Prepare and Grease Your Baking Dish
Begin by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter to both prevent sticking and infuse a subtle buttery flavor that complements the sausage and cheddar perfectly.
Step 2: Layer Half of Your Potatoes and Toppings
Arrange half of your thinly sliced potatoes evenly in the baking dish. On top of this layer, sprinkle half of the diced onions, shredded cheddar cheese, and crumbled sausage. This layering technique ensures every bite bursts with balanced flavors and textures.
Step 3: Add the Second Layer
Now layer the remaining potatoes, onions, cheese, and sausage on top. This double-layering method creates a rich, satisfying casserole with hearty layers that bake up tender and flavorful throughout.
Step 4: Whisk the Egg Mixture
In a separate bowl, thoroughly whisk together the eggs, milk, garlic powder, salt, and black pepper. This mixture will soak into the potato layers, binding everything together while adding creaminess and subtle seasoning.
Step 5: Pour Egg Mixture Over the Layers
Evenly pour the egg mixture over your layered potatoes and toppings. Make sure the liquid settles between the layers for moist and tender results after baking.
Step 6: Cover and Bake
Cover the casserole with foil and bake for 40 minutes to allow the potatoes to cook through and the egg mixture to set slowly without browning too quickly.
Step 7: Finish Baking Uncovered
Remove the foil and bake for an additional 15 minutes or until the top is beautifully golden and a knife inserted in the center comes out clean, signaling it’s cooked perfectly all the way through.
Step 8: Cool and Serve
Allow the casserole to cool for 5 minutes before slicing. This resting time helps the casserole set, making it easier to serve and enhancing the flavors as they settle.

Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and refrigerate for up to 3 days. This makes for a quick, delicious meal when your schedule gets busy.
Freezing
You can freeze the casserole either as a whole or in portions. Wrap it tightly with plastic wrap and foil before freezing, and it will keep well for up to 2 months.
Reheating
Reheat individual portions in the microwave or warm the full casserole in the oven at 350°F (175°C) until hot throughout, usually about 20 minutes. Adding a little moisture like a splash of milk helps maintain its creamy texture.
FAQs
Can I use a different type of cheese?
Absolutely! While cheddar adds a sharp flavor, you can try Monterey Jack, mozzarella, or even pepper jack for a little extra spice. Each cheese will change the character slightly, but all deliciously complement the sausage and potatoes.
Is it necessary to cook the sausage beforehand?
Yes, cooking the sausage before adding it to the casserole ensures it’s fully cooked and safe to eat, plus it releases flavorful fats that blend beautifully with the other ingredients.
Can I make this casserole vegetarian?
Definitely. Simply omit the sausage and consider adding sautéed mushrooms or spinach for savory depth. You might also want to add a bit more cheese or seasoning to keep it flavorful.
What type of potatoes work best?
Starchy potatoes like Russets are ideal because they become tender inside the casserole while holding their shape. Waxier potatoes can work but might result in a slightly different texture.
Can I prepare this recipe the night before?
Yes! Assemble your casserole, cover it tightly, and refrigerate overnight. Bake it the next morning or evening, adding an extra few minutes to the baking time since it will be cold going into the oven.
