Preheat the oven to 350°F. Cover a baking sheet with tin foil and grease with Crisco. You’ll thank me later.
Mix sauce ingredients well and set aside.
Mix ground beef, onion, garlic, bread crumbs, eggs, and milk with your hands until nicely combined. Mix in all but 1/3 cup of the sauce.
Dump your meatloaf mixture onto the prepared baking sheet and form it into a mound or loaf shape. It should hold because the meat is awesome like that. Top with the remaining sauce.
Bake for an hour and a half, checking occasionally for doneness. Depending on your shape, it may require more or less time.
Serve with white rice or homemade mashed potatoes!
