- 3 tablespoons butter
- ½ cup milk
- Salt, to taste
- Black pepper, to taste
For the Ground Beef Filling
- 1 pound (450g) ground beef
- 1 medium onion, finely chopped
- 3 garlic cloves, minced
- 2 tablespoons tomato paste
- 1 teaspoon paprika
- 1 teaspoon Italian seasoning
- Salt and pepper, to taste
- 1 tablespoon olive oil
For the Topping
- 2 cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- Fresh parsley (optional)
Step-by-Step Method
Step 1: Prepare the Mashed Potatoes
Peel and cut the potatoes into chunks, then boil them in salted water until fork tender, about 15–20 minutes.
Drain the potatoes and mash them with butter and milk until smooth and creamy. Season with salt and black pepper. Set aside.
Step 2: Cook the Ground Beef
Heat olive oil in a large skillet over medium heat.
Add the chopped onion and cook for about 3–4 minutes until soft.
Stir in the garlic and cook for another minute.
Add the ground beef and cook until browned, breaking it apart with a spoon.
Mix in the tomato paste, paprika, Italian seasoning, salt, and pepper. Let everything simmer for about 5 minutes so the flavors come together.
Step 3: Assemble the Casserole
Preheat your oven to 375°F (190°C).
Lightly grease a baking dish.
Spread half of the mashed potatoes evenly across the bottom.
Add the seasoned beef mixture as the second layer.
Cover with the remaining mashed potatoes.
Top generously with mozzarella cheese and Parmesan cheese.
Step 4: Bake
Bake for 20–25 minutes, or until the cheese is melted and bubbly.
For a golden brown top, broil for an additional 2–3 minutes.
Allow the casserole to rest for about 10 minutes before serving.
Cooking Tips
- I usually use leftover mashed potatoes to save time.
- Don’t overcook the beef or it may become dry after baking.
- Add cooked mushrooms, peas, carrots, or corn for extra flavor and nutrition.
- Freshly shredded cheese melts much better than pre-shredded cheese.
- Let the casserole cool slightly before slicing to help it hold its shape.
Serving Suggestions
This casserole is filling on its own, but I love serving it with:
- Fresh green salad
- Garlic bread
- Roasted broccoli
- Steamed green beans
- Buttered dinner rolls
- Pickles for a tangy contrast

Frequently Asked Questions (FAQs)
1. Can I make this casserole ahead of time?
Yes! Assemble the casserole up to a day in advance, cover it tightly, and refrigerate. Bake just before serving, adding a few extra minutes to the baking time if it’s coming straight from the fridge.
2. Can I use ground turkey instead of beef?
Absolutely. Ground turkey or ground chicken are great lighter alternatives and work just as well in this recipe.
3. What cheese works best?
Mozzarella gives a perfectly gooey topping, but cheddar, Monterey Jack, Colby, or a blend of cheeses also taste fantastic.
4. Can I freeze this casserole?
Yes. Once cooled, wrap it well and freeze for up to three months. Thaw overnight in the refrigerator before reheating for the best texture.
5. How do I keep the mashed potatoes creamy?
Use warm milk and butter when mashing, and avoid overmixing. This helps keep the potatoes smooth, fluffy, and creamy instead of becoming gummy.
