Preheat the Oven:Set your oven to 180°C (350°F) and lightly grease a medium baking dish with butter or olive oil.

Prepare the Potatoes:Peel and slice the potatoes into thin rounds. Toss them with salt, pepper, paprika, and oregano. Set aside while you prepare the meat.

Cook the Minced Meat:Heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3–4 minutes until soft. Add the minced garlic and cook for another minute until fragrant.Add the ground meat and cook until browned, breaking it apart with a spatula. Season with salt, pepper, and paprika. If using, stir in chopped tomato for a light tangy flavor. Remove from heat.

Make the Creamy Garlic Sauce:In a saucepan, melt butter over medium heat. Add flour and whisk continuously for 1–2 minutes to form a roux.Gradually pour in the milk and whisk until smooth and thickened. Stir in the cream, minced garlic, salt, and pepper. Simmer for another 2–3 minutes, stirring constantly, until the sauce is velvety and aromatic.

Assemble the Casserole:Spread half of the potato slices evenly in the baking dish. Spoon half of the cooked minced meat on top. Pour some creamy garlic sauce over the meat layer and sprinkle with a little mozzarella.Repeat with the remaining potatoes, meat, and sauce. Finish with the rest of the mozzarella and Parmesan cheese on top for that irresistible golden crust.

Bake to Perfection:Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for another 15–20 minutes until the top is golden brown and bubbly.

Garnish and Serve:Let the casserole cool slightly before slicing. Garnish with chopped parsley and serve warm. Enjoy your cheesy, creamy, garlicky masterpiece!
