Step-by-Step Instructions
Prepare the Potatoes
Preheat your oven to 425°F (220°C).
Wash the potatoes thoroughly and cut them into bite-sized pieces.
If using larger potatoes, cut them into approximately 1-inch cubes so they cook evenly.
Place the potatoes in a large bowl.
Add olive oil, garlic powder, paprika, Italian seasoning, salt, and black pepper.
Toss until every piece is evenly coated.
Spread the potatoes in a large baking dish or oven-safe casserole dish.
Roast for 15 minutes before adding the meatballs.
This gives the potatoes a head start and helps create the golden edges seen in the finished dish.
Prepare the Meatballs
While the potatoes are roasting, add the ground beef, breadcrumbs, egg, Parmesan, garlic, Italian seasoning, onion powder, salt, pepper, and parsley to a large bowl.
Mix gently until just combined.
Avoid overmixing because this can make the meatballs dense.
Shape the mixture into approximately 18–20 small meatballs.
Heat the olive oil in a large skillet over medium-high heat.
Brown the meatballs for approximately 5–7 minutes, turning occasionally.
They do not need to be completely cooked at this stage because they will finish cooking in the oven.
Make the Creamy Garlic Sauce
Melt the butter in a saucepan over medium heat.
Add the minced garlic and cook for approximately 30 seconds, until fragrant.
Whisk in the flour and cook for about 1 minute.
Slowly add the broth while whisking continuously.
Pour in the heavy cream and continue whisking until smooth.
Add the cream cheese and stir until completely melted.
Add the Parmesan, Italian seasoning, salt, and black pepper.
Cook for approximately 2–3 minutes, until the sauce becomes creamy and slightly thickened.
Do not allow the sauce to boil aggressively.
Assemble the Casserole
Remove the partially roasted potatoes from the oven.
Arrange the browned meatballs among the potatoes.
Pour the creamy garlic sauce evenly over the meatballs and potatoes.
Sprinkle the mozzarella and Parmesan over the top.
Make sure the cheese is distributed evenly for a golden, bubbling finish.
Bake
Reduce the oven temperature to 400°F (200°C).
Bake uncovered for approximately 20–25 minutes.
The potatoes should be completely tender, the meatballs cooked through, and the cheese melted and golden.
For extra browning, switch the oven to broil for 1–2 minutes at the end.
Watch carefully during broiling to prevent the cheese from burning.
The ground beef should reach an internal temperature of 160°F (71°C).
Remove the casserole from the oven and let it rest for 5 minutes.
Finish with freshly chopped parsley before serving.
Best Tips
Cut the potatoes into similar-sized pieces so they cook evenly.
Small baby potatoes are especially convenient because they require very little preparation.
Do not overmix the meatball mixture. Gentle mixing keeps the meatballs tender.
Browning the meatballs before baking adds much more flavor and gives them an attractive caramelized exterior.
For the creamiest sauce, use softened cream cheese and add it gradually.
Let the casserole rest for a few minutes before serving so the sauce can thicken slightly.
Fresh parsley added at the end provides a bright contrast to the rich creamy sauce.
Best Ingredient Options
Ground beef with around 80–90% lean meat works particularly well because it provides enough fat for juicy meatballs without making the casserole excessively greasy.
Ground turkey or chicken can be substituted for beef if preferred.
Yukon Gold potatoes have a naturally buttery texture, while baby potatoes hold their shape well during baking.
Mozzarella gives you a stretchy cheese topping, while Parmesan contributes a deeper savory flavor.
You can replace heavy cream with half-and-half for a lighter sauce, although the sauce will be slightly less rich.
Recipe Variations
Cheesy Mushroom Version
Add sliced mushrooms to the casserole before baking for an earthy, savory flavor.
Spicy Meatball Casserole
Add ½ teaspoon of red pepper flakes to the meatball mixture and a little cayenne to the creamy sauce.
Chicken Meatball Version
Replace the ground beef with ground chicken and use chicken broth in the sauce.
Vegetable Version
Add broccoli florets, sliced bell peppers, zucchini, or spinach for extra vegetables.
Extra-Cheesy Version
Add another ½ cup of mozzarella over the casserole during the final 10 minutes of baking.
What to Serve With
This casserole is filling enough to serve as a complete meal, but a fresh side salad pairs beautifully with it.
Steamed green beans, roasted broccoli, or asparagus can add freshness to the plate.
For a lighter side, serve it with a simple cucumber and tomato salad.
Crusty bread is also excellent for soaking up the creamy garlic sauce.
Make-Ahead Instructions
The meatballs can be prepared up to 24 hours in advance.
Store the uncooked meatballs covered in the refrigerator until ready to use.
The potatoes can also be washed and cut ahead of time.
For the best texture, prepare the creamy sauce shortly before assembling the casserole.
If assembling the entire dish ahead of time, refrigerate it covered and bake within 24 hours.
Allow the cold casserole to sit at room temperature for approximately 15 minutes before baking.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Store in the refrigerator for up to 3–4 days.
Keep refrigerated at 40°F (4°C) or below.
Reheating
Reheat individual portions in the microwave for approximately 2–3 minutes, stirring or rotating halfway through if necessary.
For better texture, reheat the casserole in a 350°F (175°C) oven until hot throughout.
Cover loosely with foil during oven reheating to prevent the cheese and potatoes from drying out.
Freezing
The casserole can be frozen, although the creamy sauce may change slightly in texture after thawing.
For best results, freeze portions in airtight freezer-safe containers.
Freeze for up to 2 months.
Thaw overnight in the refrigerator before reheating.
For the best texture, add a small amount of fresh cream or broth when reheating if the sauce appears too thick.
Common Mistakes to Avoid
Do not skip browning the meatballs. It adds flavor and helps create a beautiful golden exterior.
Avoid cutting the potatoes too large because they may remain firm while the meatballs and cheese are already finished.
Do not overcrowd the baking dish. A little space around the potatoes helps them roast rather than steam.
Avoid boiling the cream sauce aggressively because the dairy can separate.
Do not overmix the meatball mixture because this can result in tough meatballs.
Do not rely only on appearance to determine whether the meatballs are cooked. Use a food thermometer and make sure the center reaches 160°F (71°C).
