Ingredients
Servings
6
- 1 1/2 pounds ground beef (80/20)
- 1 cup breadcrumbs
- 1/2 cup milk
- 1 large egg
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1/4 cup ketchup, plus extra for topping
- 2 teaspoons Worcestershire sauce
- 1 teaspoon dried Italian seasoning or dried oregano
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 4 large russet potatoes, peeled and cut into chunks
- 1/2 cup whole milk (for mashed potatoes)
- 3 tablespoons unsalted butter
- Salt and pepper, to taste (for mashed potatoes)
- Fresh parsley, chopped (optional, for garnish)
Instructions
-
Preheat your oven to 375°F (190°C).
-
Place peeled and chopped russet potatoes in a large pot. Cover with cold water, add a pinch of salt, and bring to a boil. Cook until potatoes are tender, about 15 minutes.
-
While the potatoes boil, prepare the meatloaf mixture. In a large mixing bowl, gently combine ground beef, breadcrumbs, milk, egg, finely chopped onion, minced garlic, 1/4 cup ketchup, Worcestershire sauce, Italian seasoning, salt, and black pepper. Mix just until combined — avoid overmixing to keep the meatloaf tender.
-
Drain the potatoes and return them to the pot. Add butter and 1/2 cup whole milk, then mash until creamy and smooth. Season with salt and pepper to taste. Set aside.
-
Lightly grease a 9x13 inch casserole dish. Spread the meatloaf mixture evenly in the dish to form a flat layer.
-
Spread the creamy mashed potatoes evenly over the meatloaf layer.
-
Brush an additional thin layer of ketchup over the mashed potatoes for a classic glaze. Sprinkle with freshly chopped parsley if using.
-
Bake uncovered in the preheated oven for 45-50 minutes, or until the meat is fully cooked and the top begins to brown lightly.
-
Remove from the oven and let the casserole rest for 5-10 minutes before slicing.
-
Cut into squares and serve warm. Refrigerate leftovers within 2 hours in an airtight container for up to 4 days, or freeze for up to 3 months.
