Ingredients

For the Burger:

  • 2 pounds of 85/15 ground sirloin
  • 1 cup of cremini mushrooms
  • 1 cup of domestic mushrooms
  • soy sauce to taste
  • Worcestershire to taste
  • Tabasco to taste
  • 2 tablespoons of olive oil or bacon fat drippings from the cooked bacon
  • Kosher salt and cracked black pepper to taste

For the Toppings:

  • 2 thickly sliced sweet onions
  • 1 teaspoon of unsalted butter
  • 1 teaspoon of sugar
  • blue cheese crumbles
  • 8 crispy cooked bacon strips
  • cooked onion rings my version is here
  • 8 slices of mozzarella cheese
  • 4 to asted brioche buns

Instructions

  • Caramelized onions: In a large sauté pan on medium high heat add in the butter and caramelize the onions until golden brown. Add in the sugar to help brown. Note: May take up to 30 to 40 minutes to caramelize.
  • Preheat the grill to high (450° to 550°).
  • Burger: Add the mushrooms to a food processor and blend until smooth. Add the pureed mushrooms to a large bowl and thoroughly mix together with the ground sirloin, soy sauce, Worcestershire, Tabasco, salt and pepper. Form 8 patties with your hands and set on a sheet pan lined with parchment paper.
  • Brush the burgers with the olive oil, season them lightly with salt and pepper, and add them to the grill oiled side down. Once they are on the grill brush the other side with olive oil and season with salt and pepper. Cook for 3 to 4 minutes on each side or until golden brown grill marks have been formed or to your desired internal temperature have been achieved.
  • To keep the flames down use ice cubes were fire is consuming the burger to help tone down the flames and smoke.
  • Toast the brioche buns on the grill for 2 minutes until crispy.
  • To serve: place 1 cooked burger patty down on the brioche bun followed up with a slice of mozzarella cheese and then repeat the process again. Add on 2 tablespoons of the caramelized onions, 2 strips of bacon, and then 1 tablespoon of the blue cheese crumbles. Top it off with a few cooked onions rings, and then of course the top of the bun. Enjoy!
