Prepare the meatloaf mixture: In a big bowl, mix together ground beef, breadcrumbs soaked in water, onion, garlic, eggs, Worcestershire sauce, salt, pepper, and dried thyme. Stir thoroughly.
Form the meat mixture into a loaf shape in the baking dish.
Prepare the topping by mixing ketchup, brown sugar, and Dijon mustard in a small bowl. Put on top of the meatloaf.
Cook in the oven for 50-60 minutes, or until the inside reaches a temperature of 160°F (71°C).
Prepare mashed potatoes: While the meatloaf is cooking, put diced potatoes in a big pot and cover them with cold water. Sprinkle a little salt and heat until boiling. Cook for 15 to 20 minutes, or until soft. Drain the liquid and put it back in the pot. Put milk and butter. Crush until soft and smooth. Add salt and pepper to taste.
Put together and bake: After the meatloaf is finished baking, cover the top with mashed potatoes. Put some grated cheddar cheese on top. Cook under the broiler for 3-5 minutes, or until the cheese is melted and bubbly.
Let the meatloaf sit for 10 minutes before cutting and serving. Sprinkle with chopped parsley.
Enjoy this tasty meatloaf with mashed potatoes and cheese!
