Step 1

Preheat oven to 350F, with rack on middle position. Place large pan of water on lower rack underneath.

Step 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.

Step 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.

Step 4

Form beef mixture into a loaf (roughly 2x5xin a larger baking dish.

Step 5

In a bowl, combine brown sugar, coarse mustard, and ketchup. Pour half of this sauce over the meatloaf.

Step 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.

Step 7

Let meatloaf sit at room temp about 10 minutes before cutting into it. Serve, and drizzle with any leftover sauce.
