In a large bowl combine onion, crackers, eggs, garlic, ketchup, mustard, worcestershire sauce, and bouillon. Mix well.
Add ground beef and knead together until fully incorporated. If mixture is too wet, knead in additional crushed crackers.
Press into a 10x5 loaf pan and cover with foil. Bake at 350 degrees for 60 minutes.
While meatloaf is baking, whisk together ingredients for glaze.
After 60 minutes, uncover and drain off any pooling liquid. Baste top with glaze. Return to oven uncovered for an additional 15 minutes, until the center of your loaf reaches 160 degrees.
