Cook bacon in a medium nonstick skillet over medium-low heat, until crispy and fat renders, about 10 minutes. Remove bacon with a slotted spoon to a paper towel-lined plate, reserving renderings in the skillet. Cook the onions and garlic in the pan drippings until brown, about 15 minutes. Let cool.
Meanwhile, in a large bowl whisk the eggs, mustard, hot sauce, Worcestershire, cream, salt, and pepper. Add the meat, cheese, parsley, and cooked onion. Chop and add the bacon. Mix with a fork until evenly blended. Whisk the glaze ingredients together in a bowl.
Dampen hands with water and on a foil-lined cookie sheet, pat mixture into a loaf shape. Bake until an instant-read thermometer inserted into the center of the loaf registers 155 degrees F, about 1 hour. Spread the glaze onto the meatloaf after about 50 minutes. Let loaf rest for at least 10 minutes before serving.
