Ingredients:
For the Meatballs:
- 1 lb (450g) ground beef
- 1/2 cup breadcrumbs
- 1/4 cup milk
- 1 egg
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 1/4 cup fresh parsley, chopped
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp paprika
- 1/2 tsp dried oregano
- 1 tbsp olive oil (for browning)
For the Mashed Potatoes:
- 2 lbs (900g) potatoes, peeled and chopped
- 1/2 cup milk (warm)
- 1/4 cup heavy cream
- 1/4 cup butter
- Salt and pepper to taste

For the Bake:
- 1 1/2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup marinara or tomato sauce (optional, for layering)
- Chopped parsley for garnish
Preparation:
Step 1: Prepare the Mashed Potatoes
Start by boiling your peeled and chopped potatoes in salted water for about 15-20 minutes, or until they’re fork-tender. Drain and return them to the pot. Add butter, warm milk, and cream. Mash until smooth and creamy. Season with salt and pepper to taste. Set aside.
Step 2: Make the Meatball Mixture
In a large mixing bowl, combine ground meat, breadcrumbs soaked in milk, egg, onion, garlic, parsley, salt, pepper, paprika, and oregano. Mix everything until well combined but don’t overwork it, or your meatballs might turn out tough.
Step 3: Form and Cook the Meatballs
Shape the meat mixture into small, even-sized balls—about 1 to 1.5 inches in diameter. Heat olive oil in a skillet over medium heat and brown the meatballs on all sides. You don’t need to cook them all the way through—they’ll finish baking in the oven.
Step 4: Assemble the Bake
Preheat your oven to 375°F (190°C). In a large baking dish, spread half the mashed potatoes as the bottom layer. Place the meatballs evenly on top. Spoon a little marinara sauce over the meatballs if you like. Then, spread the remaining mashed potatoes over the top, covering the meatballs. Sprinkle shredded mozzarella and Parmesan evenly over the surface.
Step 5: Bake and Finish
Bake the dish uncovered for 25-30 minutes or until the cheese is bubbly and golden brown. If you want a crispier top, broil for an additional 2-3 minutes. Remove from oven, let it rest for a few minutes, then garnish with chopped parsley.
Variation
- Cheesy Upgrade: Add cheddar or gouda for a different cheese twist.
- Veggie Boost: Mix in sautéed mushrooms, peas, or spinach with the mashed potatoes.
- Spicy Kick: Add crushed red pepper flakes or a dash of hot sauce to the meatball mixture.
- Gravy Alternative: Instead of tomato sauce, use a rich brown gravy for a classic comfort food flavor.
- Low Carb Option: Swap out mashed potatoes for mashed cauliflower to reduce carbs.

COOKING Note:
Don’t overcrowd the meatballs when browning, and don’t skip browning altogether—it adds tons of flavor. Also, letting the bake rest for 5–10 minutes after baking helps it set up for easier slicing and serving.
Serving Suggestions:
This dish is hearty enough to stand on its own, but you can elevate it with:
- A crisp green salad
- Roasted or steamed vegetables (broccoli or green beans work great)
- A glass of red wine or sparkling water with lemon
Tips:
- Use Yukon Gold potatoes for a creamier mash.
- You can prep meatballs and mashed potatoes ahead of time and store them in the fridge until ready to assemble.
- To make cleanup easier, line your baking dish with parchment paper or grease it well.
- Don’t be shy with seasoning—taste as you go!
