Burgers with Sauteed Mushrooms, Swiss Cheese, Caramelized Onions, and Crispy Bacon

I’ve been eating a lot of burgers lately. When I want to do something different than the classis burger with American cheese, lettuce, tomato, and red onion, I often go in the direction of a mushroom, bacon, and Swiss burger.
This recipe includes a quick and tangy homemade vinegar-heavy BBQ sauce to go on top of the burger.

Ingredients

For the Homemade BBQ Sauce:

  • 2 Tbsp butter
  • ¼ red onion, finely minced
  • 1 garlic clove, finely minced
  • ½ cup ketchup
  • ½ cup apple cider vinegar
  • 1 Tbsp hot sauce of choice
  • ¼ tsp freshly-ground black pepper
  • 1 tsp kosher salt
  • ¼ cup brown sugar
  • 1 tsp smoked paprika
  • 1 tsp sweet paprika

For the Remaining Burger Components:

  • 24 oz ground beef, 75-80% lean
  • 4 slices Swiss cheese
  • 4 slices thick-cut bacon, cooked until they are crispy
  • 4 Tbsp salted buttered, softened
  • 1 large onion, thinly-sliced
  • 8 oz mushrooms, sliced
  • Kosher salt & freshly-ground black pepper, to taste
  • 4 burger buns of choice

Instructions

For the Homemade BBQ Sauce:

  • Heat 2 Tbsp butter in a small sauce pot on the stove.
  • Add the minced onion and cook on medium-low heat for 8 minutes.
  • Add the minced garlic and cook for an additional 2 minutes.
  • Add the remaining BBQ sauce ingredients and bring to a simmer.
  • Remove from the heat, and taste the seasoning level.
  • Add more hot sauce, salt, pepper, vinegar, ketchup, or brown sugar based on your desired sauce profile.
  • Use an immersion blender to blend the sauce to a smooth consistency.
  • Set the sauce aside for later use.

For the Remaining Burger Components:

  • Preheat grill to 500F.
  • Cook your bacon on the stove and set aside for later.
  • Caramelize the onions in butter and set them aside for later.
  • Cook the sliced mushrooms in butter until they are tender and cooked.
  • Season the mushrooms with kosher salt & freshly-ground black pepper to taste and set the cooked mushrooms aside for later.
  • Prepare your ground beef patties.
  • Salt the burger patties, and grill them at 500F until they are cooked on one side.
  • Flip the patties and add continue to cook for an additional 3 minutes.
  • Before the burgers are cooked through, add the Swiss cheese and allow for the cheese to melt.
  • Butter the burger buns and briefly grill them over a warm section of the grill that is not directly above the flame.
  • Set the toasted buns aside on a plate when they are ready.
  • When the burgers are almost cooked, remove them from the grill and allow them to rest on a plate for 3 minutes before serving.
  • Top the Swiss cheese burgers with the bacon, mushrooms, and caramelized onions that you cooked earlier.
  • Add some homemade BBQ sauce on top, and enjoy the burgers while they are still warm.

Notes

These burgers are best eaten right after they are made.
