Method
- Add the ground beef, egg, breadcrumbs, Worcestershire sauce, garlic powder, onion powder, salt, and pepper to a medium mixing bowl. Use your hands to gently combine everything until just mixed, about 30 seconds of handling.
- Divide the meat mixture into 4 equal portions, roughly 6 ounces each. Shape each portion into an oval patty about 3/4 inch thick, pressing a shallow dimple into the center with your thumb.
- Place your cast iron skillet over medium high heat and let it preheat for 3 full minutes. Add 1 tablespoon of vegetable oil and swirl to coat the bottom evenly.
- Place the patties in the hot skillet, leaving at least 1 inch between each one. Press down gently once to ensure full contact with the pan, then leave them completely alone for 4 minutes.
- Flip each patty using a spatula and cook for another 4 minutes. Insert your thermometer into the thickest part of one patty. Remove the patties when they reach 155°F internally. Transfer to a clean plate.
- Reduce heat to medium and add the butter to the same skillet. Let it melt and foam, then add the sliced onions, spreading them into an even layer.
- Cook the onions for 8 to 10 minutes, stirring every 2 minutes, until they turn golden brown and smell deeply sweet. Add the minced garlic during the final minute.
- Sprinkle the flour over the onions and stir constantly for 1 full minute. Make sure every bit of flour gets coated in fat and no dry patches remain.
- Pour in the beef broth slowly while whisking constantly. Add the Worcestershire sauce and dried thyme, continuing to whisk until the mixture is completely smooth.
- Bring the gravy to a gentle boil, then reduce heat to medium low. Let it simmer for 5 minutes, stirring occasionally, until it coats the back of a spoon.
- Nestle the rested patties back into the gravy. Spoon some gravy and onions over the top of each patty, then let everything simmer together for 3 minutes.
- Taste the gravy and adjust salt and pepper as needed. Transfer each patty to a plate and spoon generous amounts of onion gravy over the top. Serve immediately.
Notes
Let your patties rest for 3 minutes after the initial sear before returning them to the gravy. This redistributes juices throughout the meat, preventing them from flooding out when you cut into the steak. Store leftovers in an airtight container for up to 4 days refrigerated or 3 months frozen.
