Instructions

1. Preheat oven to 350F, with rack on middle position. Place large pan of water on lower rack underneath.
2. In a large heavy saucepan, saute onion and garlic in olive oil until soft. Add a pinch of kosher salt, pinch of pepper, and the thyme. Saute 30 seconds more, and transfer to large bowl.
3. Add 1 tsp kosher salt, 1 tsp black pepper, Worcestershire sauce, eggs, beef broth, and bread crumbs. Whisk by hand to combine ingredients. Add ground beef and stir with wooden spoon until fully combined.
4. Form beef mixture into a loaf (roughly 2x5x8) in a larger baking dish.
5. In a bowl, combine brown sugar, coarse mustard, and ketchup. Pour half of this sauce over the meatloaf.
6. Bake about 50 minutes. Brush on more sauce, reserving a little for serving, if desired. Bake 10 more minutes or until meatloaf is cooked through.
7. Let meatloaf sit at room temp about 10 minutes before cutting into it. Serve, and drizzle with any leftover sauce.
