Chef Manning's Better Burger, topped with pepper jack cheese, is for the classic burger lover.


  • 32 ounces white mushrooms, sliced
  • 3 medium Vidalia onions, sliced
  • 2 pounds 80/20 fresh ground chuck
  • Salt and pepper 
  • 8 slices pepper jack cheese
  • 1 bunch romaine lettuce, thinly sliced
  • 2 Louisiana heirloom tomatoes, thickly sliced
  • 4 toasted sourdough buns    


Preheat the oven to 375ºF. On a large sheet tray, roast the mushrooms and onions until the mushrooms turn a rich brown color, about 30 to 40 minutes. Reserve half of this mixture for garnishing the burgers.

In a food processor, purée the remaining mushroom mixture into a paste. In a large bowl, combine the mushroom purée and the ground chuck. Form into four patties of equal size. 

Cook the patties on a hot griddle. Season with salt and pepper. Flip after 5 minutes and season with salt and pepper again. Cook the burgers to medium, about 10 minutes total cooking time. 

While still on the griddle, top each burger with 2 slices of pepper jack cheese and a handful of the remaining mushroom mixture. Cover with a lid for 30 seconds in order to melt the cheese and reheat the mushrooms.

To serve, place each cooked burger patty, along with some lettuce and tomato, on a toasted bun.
