2 pounds ground beef (85-percent lean)

Kosher salt and freshly ground black pepper

1/4 cup Dijon mustard 

3 tablespoons soy sauce

1 teaspoon sugar

6 slices Swiss cheese

1 tablespoon olive oil

8 ounces chopped baby bella or cremini mushrooms

2 teaspoons fresh thyme leaves or 1 teaspoon dried

2 cloves garlic, minced

6 yeasty buns


  1. Preheat the grill to medium-high heat. 
  2. Form the beef into 6 burgers; sprinkle with salt and pepper. To make the glaze, mix together the mustard, soy sauce and sugar in a small bowl. 
  3. Grill the burgers until desired doneness, 4 to 5 minutes per side for medium rare, brushing the burgers with the glaze about halfway through. A minute before removing the burgers from the grill, top with the cheese. 
  4. Meanwhile, heat the oil in a large skillet over medium-high heat. Cook the mushrooms until beginning to soften, about 5 minutes. Add the thyme and garlic and cook until the mushrooms are soft, about 3 minutes more. Season with salt and pepper. 
  5. Toast the buns and serve the burgers with the mushroom topping.
