In another bowl, make the glaze by mixing ketchup, brown sugar, mustard powder, onion powder, paprika, and tomato paste. Reserve half of the glaze in a separate bowl for after the meatloaf is cooked. Set aside.
Add the mashed potatoes into the “bowl” and smooth out. Top the mashed potatoes with the remaining meat, smooth out, coat the top with the raw meat glaze, and fold the slices of bacon over the top of the meat. Cover with foil and bake for 1 hour, remove the foil after 30 minutes and carefully drain some of the fat before putting it back into the oven.
