How to Make It
Step 1: Make the Mashed Potatoes
Boil the potatoes until fork tender (10–12 minutes). Drain, then mash with milk, butter, salt, and pepper until smooth and creamy.
Step 2: Prepare the Meat Sauce
In a skillet, heat olive oil and cook the onion and garlic until soft. Add the ground beef, breaking it up and cooking until browned. Stir in tomato sauce and seasoning; simmer for 5–7 minutes until slightly thickened.
Step 3: Assemble the Casserole
Preheat oven to 375°F (190°C). In a greased baking dish, layer half the mashed potatoes, followed by half the meat sauce, and a layer of cheese. Repeat the layers once more, finishing with a generous cheese topping.
Step 4: Bake & Serve
Bake for 20–25 minutes, or until bubbly and the cheese is golden. Let it rest 5 minutes before serving.
