Sauce Diane

ingredients

  • 2 cups mushrooms, thinly sliced
  • 1 shallot, minced
  • 1 garlic clove, grated
  • 1 tablespoon freshly ground black pepper
  • 2 tablespoons cognac
  • 1/2 cup beef stock

To make the Caramelized Onions:

Method

  • Step 1

    Heat a pan over medium heat and add a drizzle of olive oil.

  • Step 2

    Add the sliced onions and cook for about 10 minutes, stirring occasionally.

  • Step 3

    Add the salt, sugar, and Worcestershire sauce.

  • Step 4

    Lower the heat and cook for 45 more minutes, stirring often to prevent burning. Set aside.

To Cook the Burgers:

  • Step 1

    Divide the ground beef into 4 equal portions and form into loose patties.

  • Step 2

    Heat a cast iron or stainless-steel skillet over high heat.

  • Step 3

    Add a small amount of neutral oil and place two patties in the skillet. Smash each patty with a spatula until thin.

  • Step 4

    Season with salt and black pepper.

  • Step 5

    Sear each side for about 2 minutes. Add a slice of Swiss cheese on top and cover with a lid until the cheese is melted. Repeat for the remaining patties.

To Make the Sauce Diane:

  • Step 1

    In the same skillet over medium heat, add a bit more olive oil and sauté the shallots for 1 minute.

  • Step 2

    Add the mushrooms and cook until lightly browned. Sprinkle with a pinch of salt and add the garlic.

  • Step 3

    Cook for 5 more minutes, then pour in the cognac and flambé until the alcohol burns off.

  • Step 4

    Add the beef stock and reduce by half.

  • Step 5

    Stir in the heavy cream and reduce until the sauce thickens to the desired consistency.

  • Step 6

    Finish with cold butter and mustard. Stir and season with salt to taste.

To Assemble the Burgers:

  • Step 1

    Toast the burger buns and place a generous scoop of caramelized onions on the bottom bun.

  • Step 2

    Add the cooked burgers with melted cheese and spoon the Diane sauce over the top.

  • Step 3

    Sprinkle with chives if desired, and cap with the top bun.
