Preheat oven to 350°F (175°C). In a large bowl, combine ground beef, chopped onion, minced garlic, breadcrumbs, egg, milk, salt, black pepper, and Worcestershire sauce. Mix gently to avoid overworking. Shape into 4-5 oval patties.

Heat vegetable oil in a large skillet over medium-high heat. Brown the patties for 2-3 minutes on each side. Transfer to a 9x13-inch baking dish.

In the same skillet, melt butter over medium heat. Stir in flour and cook for 1-2 minutes forming a roux. Gradually whisk in beef broth until smooth. Add Worcestershire sauce, dried thyme, salt, and pepper. Simmer for 3-4 minutes until thickened.
