Method
Make the patties
- Mix ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper until evenly combined, then form into 4 oval patties about 3/4 inch thick.
- Sear patties in a skillet over medium-high heat for 3–4 minutes per side until browned, then remove and set aside.
Cook the gravy
- Melt butter in the same pan, then cook onion and mushrooms over medium-high heat for 6–7 minutes until golden, stirring occasionally so the fond develops.
- Sprinkle flour over the cooked onion-mushroom mixture and cook for 1 minute, then whisk in beef broth, Worcestershire sauce, and Dijon mustard until smooth.
- Simmer the gravy for 3–4 minutes until thickens, then return patties to the pan, cover, and cook for 10–12 minutes until cooked through and fork-tender.
Serve
- Garnish with fresh thyme and serve immediately over mashed potatoes, spooning the dark mushroom gravy over the top.
Notes
Pro tip: keep the skillet hot for the first sear so the crust forms before the patties release juices. Store leftovers in an airtight container in the refrigerator up to 3 days; reheat gently on the stovetop with a splash of broth. Freeze patties and gravy up to 2 months for best texture—thaw overnight in the fridge and rewarm slowly. For a lighter option, use lean ground beef (90/10) and add 1–2 extra tablespoons breadcrumbs to maintain juiciness.
