1/2 cup beef broth
-

Instructions
In a large skillet, melt butter over medium‑low heat and add the sliced onions. Sprinkle a pinch of sugar, then let them soften and turn a deep amber, stirring occasionally – this takes about 12 minutes.
Push the onions to the side, increase heat to medium, and add the ground beef. Break it up, season with pepper and thyme, and brown until no longer pink, about 6 minutes.
Stir in garlic, Worcestershire sauce, and beef broth. Let the mixture simmer gently until it thickens, about 5 minutes, scraping up any browned bits for flavor.
