Ingredients You’ll Need
This recipe uses simple yet essential ingredients that blend beautifully to create the perfect balance of taste, texture, and color. Each component adds a special touch, making the casserole irresistible from the first slice to the last.
- Potatoes (4 large, peeled and thinly sliced): The hearty base that provides substance and soaks up all the wonderful flavors.

- Milk (1 cup): Adds creaminess and helps create that custard-like layer.
- Shredded cheddar cheese (1 cup): Offers sharpness and gooey meltiness that everyone loves.
- Diced onion (1/2 cup): Provides a subtle sweetness and slight crunch.
- Cooked turkey or beef sausage (1/2 cup, crumbled): Infuses the casserole with savory, meaty flavor.
- Garlic powder (1/2 teaspoon): Enhances the overall aroma and depth of flavor.
- Salt (1/2 teaspoon): Balances and highlights all the ingredients.
- Black pepper (1/4 teaspoon): Adds a gentle hint of spice for complexity.
- Butter (1 tablespoon, for greasing): Keeps the casserole from sticking and adds a buttery finish on the edges.
How to Make Potato and Egg Casserole with Sausage and Cheddar Recipe
Step 1: Preparing the Baking Dish
Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish generously with butter to ensure your casserole doesn’t stick and develops a golden crust along the edges.
Step 2: Layering the First Half
Take half of the thinly sliced potatoes and neatly arrange them across the bottom of the dish. Follow this with half of the diced onions, shredded cheddar cheese, and crumbled sausage. This first layer sets the savory foundation of your casserole.
Step 3: Building the Second Layer
Repeat the same layering process once again with the remaining potatoes, onions, cheese, and sausage. This double layering guarantees each serving will be packed with the delicious combination of ingredients.
Step 4: Mixing the Egg Custard
In a mixing bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until fully combined. This mixture will soak into the potatoes, binding everything together beautifully while adding creaminess and flavor.
Step 5: Pouring the Egg Mixture
Carefully pour the egg mixture evenly over your layered ingredients. You want every slice of potato to be embraced by this savory custard for the perfect texture.
Step 6: Baking Covered
Cover the casserole dish tightly with foil and bake it in your preheated oven for 40 minutes. This gentle cooking allows the potatoes to soften and the flavors to meld together without drying out.
Step 7: Finishing with a Golden Top
Remove the foil and return the casserole to the oven. Bake uncovered for another 15 minutes until the top is beautifully golden and a knife inserted in the center comes out clean. This final step creates a delightful crust and melts the cheese to perfection.
Step 8: Resting Before Serving
Let the casserole cool for about 5 minutes before slicing. This resting time helps it set slightly, making the slices hold their shape while also allowing the flavors to settle for maximum enjoyment.

Garnishes
Add a fresh touch by garnishing with chopped green onions or fresh parsley. These bright little pops of color and flavor bring a fresh contrast to the rich casserole and make your presentation look inviting.
Side Dishes
This casserole pairs wonderfully with a simple green salad or some roasted vegetables to balance the richness. For a brunch vibe, try serving it alongside fresh fruit or a light yogurt parfait to mix freshness with indulgence.
Creative Ways to Present
If you want to impress, serve individual portions in small ramekins for personal casseroles, or add a dollop of sour cream and a sprinkle of chili flakes on top to jazz up the flavor. You could even bake it inside a bread bowl for a rustic twist.
Make Ahead and Storage
Storing Leftovers
Cool any leftovers completely before storing them in an airtight container in the refrigerator. The casserole keeps well for up to 3 days and remains flavorful, making it easy to enjoy without extra effort.
Freezing
You can freeze this Potato and Egg Casserole with Sausage and Cheddar Recipe for up to 2 months. Make sure to wrap it tightly with plastic wrap and foil or use a freezer-safe container to protect against freezer burn. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until warmed through and the top is crisp again. You can also microwave individual slices, but the oven method preserves the best texture and flavor.
FAQs
Can I use different types of sausage in this casserole?
Absolutely! Whether you prefer pork, chicken, turkey, or beef sausage, all work wonderfully. Feel free to experiment with spicy or smoked varieties to suit your taste preferences.
Is it possible to make this casserole vegetarian?
Yes, you can omit the sausage and add extra veggies like bell peppers, mushrooms, or spinach to maintain heartiness and flavor without meat.
Can I prepare this casserole the night before?
Definitely. You can assemble the casserole and refrigerate it overnight before baking in the morning. This makes it perfect for busy mornings or when hosting brunch.
What cheese can I substitute for cheddar?
Cheddar is great for its sharpness and meltability, but Monterey Jack, mozzarella, or a blend of cheeses will also work well in this recipe.
How thin should the potato slices be?
A thickness of about 1/8 inch is ideal. Thin enough to cook through evenly during baking, but thick enough to provide a pleasant bite and texture.
