Ingredient Notes
Ground Meat
A blend of beef and pork creates juicy, flavorful meatballs. If preferred, use all ground beef, turkey, or chicken.
Potatoes
Yukon Gold potatoes offer a buttery flavor and hold their shape well. Russets create a softer, more tender texture.
Cheese
Combining mozzarella and cheddar gives the perfect balance of stretchiness and bold flavor, while Parmesan adds a savory finish.
Step 1: Prepare the Meatballs
In a large bowl, combine:
- Ground beef
- Ground pork
- Breadcrumbs
- Egg
- Parmesan
- Garlic
- Parsley
- Onion powder
- Italian seasoning
- Smoked paprika
- Salt
- Black pepper
Mix gently until just combined. Avoid overmixing, which can make the meatballs tough.
Roll into 1½-inch meatballs, yielding about 24 meatballs.
Step 2: Brown the Meatballs
Heat olive oil in a large skillet over medium-high heat.
Brown the meatballs on all sides, about 6–8 minutes. They do not need to be fully cooked, as they will finish cooking in the oven.
Transfer to a plate and set aside.
Step 3: Prepare the Potatoes
Preheat the oven to 375°F (190°C).
Wash and peel the potatoes if desired, then slice them into ¼-inch rounds.
In a large bowl, toss the potato slices with:
- Olive oil
- Salt
- Black pepper
- Garlic powder
- Paprika
Mix until evenly coated.
Step 4: Make the Creamy Garlic Cheese Sauce
In a medium saucepan, melt the butter over medium heat.
Add the minced garlic and cook for 1 minute until fragrant.
Whisk in the flour and cook for another minute to form a roux.
Gradually whisk in the milk and chicken broth, stirring constantly to prevent lumps.
Add:
- Dijon mustard
- Onion powder
- Italian seasoning
- Salt and pepper
Cook for 5–7 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
Remove from the heat and stir in:
- 1 cup mozzarella
- ½ cup cheddar
- ¼ cup Parmesan
Whisk until smooth and creamy.
Step 5: Assemble the Casserole
Lightly grease a 9×13-inch baking dish.
Arrange half of the seasoned potato slices in an even layer.
Place half of the browned meatballs over the potatoes.
Pour one-third of the cheese sauce over the layer.
Repeat with the remaining potatoes, meatballs, and another third of the sauce.
Spread the remaining sauce evenly over the top.
Step 6: Add the Cheese
Sprinkle the remaining:
- Mozzarella
- Cheddar
- Parmesan
Evenly across the top of the casserole.
The generous layer of cheese will melt into a bubbly, golden crust.
Step 7: Bake
Cover the baking dish tightly with aluminum foil.
Bake for 40 minutes.
Remove the foil and continue baking for 20–25 minutes, or until the potatoes are fork-tender, the meatballs are fully cooked, and the cheese is golden and bubbling.
For an extra-crispy top, broil for 2–3 minutes at the end, watching carefully to prevent burning.
Step 8: Rest Before Serving
Allow the casserole to rest for 10 minutes before serving.
This helps the sauce thicken slightly, making it easier to slice and serve.
