In a food processor, pulse half the mushrooms until finely chopped but not puréed. Transfer chopped mushrooms to a large bowl. To bowl, add the beef, bread crumbs, 2 tbsp Worcestershire sauce, ketchup, eggs, and ½ tsp garlic powder. Season with salt and pepper. Gently mix to combine. Shape into 6 oval patties.

In a 12-inch skillet, heat 2 tbsp oil on medium-high. Add patties and cook 2–3 min. per side, until browned. Transfer patties to a plate.

In skillet, heat remaining 2 tbsp oil on medium-low. Add remaining sliced mushrooms and onion. Season with salt and pepper. Cook 6–7 min., until mushrooms and onion are softened. Stir in the flour and cook 1–2 min., stirring often. Gradually add broth and remaining ½ tsp garlic powder, stirring constantly and scraping up any browned bits from bottom of pan. Bring sauce to a simmer. Season with salt and pepper. Stir in remaining 1 tbsp Worcestershire sauce.
