In a large bowl, combine fresh ground beef, breadcrumbs, an egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix gently until just combined.

Shape the beef mixture into four equal patties, each about ¾ inch thick. Make a gentle impression in the center of each patty.

Heat a skillet over medium heat and add a drizzle of olive oil. Add the patties and cook for 4-5 minutes on each side until browned.

In the same skillet, melt butter over medium heat. Add thinly sliced onions and sauté for about 10-15 minutes until caramelized.

Sprinkle flour over the onions, stirring well. Slowly pour in beef broth while continuously stirring to prevent lumps.

Stir in Worcestershire sauce, salt, pepper, and dried thyme. Bring to a gentle simmer for 5-7 minutes to thicken.

Return the cooked patties to the skillet, nestling them into the gravy. Let simmer together for an additional 5 minutes.

Plate the patties topped with onion gravy, serving with mashed potatoes or rice.
