Ingredients
  

1 lb ground beef

1 cup breadcrumbs

1/2 cup onion, finely chopped

2 cloves garlic, minced

1/2 cup milk

1 large egg

1 tablespoon Worcestershire sauce

1 teaspoon thyme

Salt and pepper to taste

4 cups mashed potatoes (prepared)

1 cup shredded cheddar cheese

1/2 cup frozen peas (optional)

Chopped parsley for garnish

Instructions
 

Preheat your oven to 375°F (190°C).

    In a large mixing bowl, combine the ground beef, breadcrumbs, chopped onion, minced garlic, milk, egg, Worcestershire sauce, thyme, salt, and pepper. Mix until fully combined.

      Grease a 9x13 inch casserole dish. Spread the meat mixture evenly across the bottom of the dish, pressing down to form an even layer.

        Bake the meatloaf base in the preheated oven for about 25 minutes until just browned.

          While the meatloaf is baking, prepare the mashed potatoes (if not already done). You can make them creamy by adding butter and extra milk to taste.

            Once the meatloaf is ready, remove it from the oven and spread the mashed potatoes evenly on top. Use a spatula to create some texture peaks for a beautiful presentation.

              Sprinkle the shredded cheddar cheese over the mashed potatoes. If using peas, scatter them on top as well.

                Return the casserole to the oven and bake for an additional 20–25 minutes, or until the cheese is melted and golden brown.

                  Remove from the oven and let it cool for a few minutes. Garnish with chopped parsley before serving.
