Ingredients
Method
- In a bowl, mix ground beef with Worcestershire sauce, soy sauce, garlic powder, and onion powder. Let rest for 30 minutes to allow flavors to meld.
- Preheat oven to 300°F (150°C). Heat a skillet over medium heat and sear the beef patties for 2-3 minutes per side to lock in juices.
- Transfer the patties to a baking dish and roast in the oven for 20-25 minutes until the internal temperature reaches 71°C (160°F).
- Caramelize onions by slicing them thinly and sautéing in a pan with a bit of olive oil over low heat for 20-25 minutes, stirring occasionally, until golden brown.
- Toast the buns and assemble the burger with cheese, caramelized onions, ketchup, and mustard.
