Method
Preheat and shape the steaks
- Preheat the oven to 350°F. Set out a 9x13 baking dish so you can transfer the patties quickly.
- Mix ground beef with breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper, then shape into 6 oval patties. Press firmly so the steaks hold their shape during baking.
Sear and bake
- Sear the patties in a skillet over medium-high heat for 2 minutes per side until browned, then place them in a 9x13 baking dish. You should see a dark-golden crust on the edges.
- Melt butter in the same skillet and sauté the sliced onion and mushrooms for 5 minutes until golden. Scrape up browned bits so they dissolve into the gravy.
- Sprinkle flour over the onion-mushroom mixture and cook for 1 minute. Stir until the flour looks slightly nutty and fully absorbed.
- Whisk in beef broth, Worcestershire sauce, and thyme until smooth, then simmer for 3 minutes. The gravy should thicken lightly and look glossy.
- Pour the gravy over the hamburger steaks, cover with foil, and bake at 350°F for 30–35 minutes until cooked through. Look for steaming bubbling gravy at the edges and a no-pink center.
Notes
For best texture, press the patties firmly so they don’t crack, and keep the skillet hot for the initial 2-minute-per-side sear. Store leftovers in the refrigerator for up to 3–4 days; reheat covered at 325°F until warmed through. Freezing is not recommended because the gravy’s texture can thin after thawing. For a lighter option, swap half the ground beef for lean ground turkey and use low-sodium beef broth.
