👩‍🍳 Instructions
Step 1: Prepare the potatoes

Peel and cut potatoes into cubes. Place in a large pot of salted water and boil for 15–20 minutes, or until fork-tender.

Step 2: Make creamy mashed potatoes

Drain the potatoes thoroughly. Add butter, milk, sour cream, garlic powder, salt, and pepper. Mash until smooth and creamy. Set aside.

Step 3: Cook the ground beef

Heat olive oil in a large skillet over medium heat. Add ground beef and cook until browned, breaking it apart as it cooks. Drain excess grease.

Step 4: Add seasonings

Add diced onion and minced garlic. Cook for 2–3 minutes until softened. Stir in tomato sauce, tomato paste, paprika, Italian seasoning, onion powder, salt, and black pepper.

Simmer for 5–7 minutes until thickened.

Step 5: Assemble the casserole

Preheat oven to 375°F (190°C). Lightly grease a baking dish.

Layer the casserole as follows:
1. Spread half of the mashed potatoes across the bottom.
2. Add half of the seasoned ground beef mixture.
3. Sprinkle a little mozzarella and cheddar cheese.
4. Spread the remaining mashed potatoes.
5. Add the remaining ground beef mixture.
6. Finish with the remaining mozzarella, cheddar, and Parmesan.
Step 6: Bake

Bake uncovered for 25–30 minutes, until the cheese is melted, bubbly, and golden brown.

Step 7: Rest and serve

Allow the casserole to rest for 10 minutes before slicing. Garnish with fresh parsley and serve warm!
