his delicious frosted meatloaf recipe eliminates the need to scoop up mashed potatoes with each bite of meatloaf. Think hamburger loaf frosted with mashed potatoes.
Turn oven on to the broil setting and line a baking sheet with foil. Cover a rack with foil and place on the baking sheet.
In a large skillet, melt the butter over medium heat and cook the onions until lightly golden and soft. Add the garlic and continue cooking until fragrant, about 30 seconds. Off the heat and set aside.
Transfer the meat mixture to the prepared rack and shape into a 9x6 loaf. Place under the broiler until browned, about 5 minutes.
Brush the top of the loaf with the ketchup mixture and return to under the broiler until bubbly, about 5 minutes.
Change the oven to the bake setting and heat to 350°F. Cook the loaf on the middle rack until the internal temperature reaches 160°F, about 1 hour
Remove the loaf and switch the oven back to the broil setting. Frost on the mashed potatoes with an offset spatula. Broil until golden. Garnish with the remaining parsley
