Instructions
Preparation Steps
In a large bowl, combine panko and milk and let sit until hydrated.
Add ground beef, egg, grated onion, garlic, Worcestershire, Dijon, ketchup, salt, and pepper. Mix gently until just combined.
Divide and shape into 4 oval patties about 0.75 inch thick. Make a shallow indent in the center of each to prevent bulging.
Heat olive oil in a large skillet over medium-high. Sear patties until browned, 2 to 3 minutes per side. Transfer to a plate.
Reduce heat to medium. Add butter, then onions and mushrooms. Cook, stirring, until softened and golden, 6 to 8 minutes. Stir in garlic for 30 seconds.
Pour in beef broth, Worcestershire, ketchup, and Dijon. Scrape up browned bits and bring to a simmer.
Whisk cornstarch with water, then slowly stream into the skillet while stirring. Simmer until the gravy thickens slightly.
Nestle patties back into the gravy. Cover and simmer until cooked through, 8 to 10 minutes, or until internal temp reaches 160°F.
Season gravy to taste with salt and pepper. Garnish with parsley and serve hot with mashed potatoes or egg noodles.
Notes
For extra tender patties, avoid overmixing the meat. You can swap mushrooms for extra onions if preferred. If the gravy gets too thick, whisk in a splash of warm broth to loosen.
