Method
- In a large bowl, combine ground beef, breadcrumbs, egg, milk, diced onion, garlic, Worcestershire sauce, salt, and pepper. Gently mix until just combined.
- Divide mixture into 6 equal portions and shape into oval patties, about 3/4-inch thick, with a slight indentation in the center.
- Heat olive oil in a large skillet over medium-high heat. Sear patties for 4-5 minutes per side until golden brown. Remove and set aside.
- In the same skillet, add butter and sliced onions. Cook for 8-10 minutes until caramelized. Add mushrooms if using and cook for 5 minutes until golden.
- Sprinkle flour over the onion mixture and stir for 1-2 minutes. Gradually whisk in beef broth, Worcestershire sauce, and thyme until smooth.
- Return patties to the skillet, nestle into the gravy, cover, and simmer on low for 15-20 minutes until internal temperature reaches 160°F.
Notes
Gently mix patties to avoid toughness. Make an indentation in patties for even cooking. Whisk flour thoroughly to prevent lumpy gravy. Store patties and gravy separately in the refrigerator for up to 3 days or freeze for up to 3 months, reheating gently with a splash of broth.
