Ingredients

Units Scale

Burgers

  • 2 pounds ground chuck (80/20), formed into 1/3 pound balls
  • 2 white onions, thinly sliced with a mandoline
  • 1/2 pound bacon, cooked until crispy and chopped
  • Salt, pepper, and garlic powder for seasoning
  • Mustard for cooking
  • Pepper jack cheese, sliced
  • Burger buns, toasted
  • Avocado oil for cooking

Baconnaise Sauce

  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 2 tablespoons mustard
  • 1/2 pound crispy chopped bacon
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon apple cider vinegar
  • 1 tablespoon all-purpose seasoning (salt, pepper, garlic)
  • 1 tablespoon red pepper flakes

Instructions

  1. Form the patties: Shape the ground chuck into 1/3 pound balls and refrigerate for 30 minutes to help them hold together during cooking.
  2. Prepare onions: Using a mandoline with safety guard or gloves, slice the white onions as thinly as possible. Squeeze out excess moisture and refrigerate until ready to use.
  3. Cook bacon: Crisp the bacon strips in a pan or griddle, then chop finely and set aside.
  4. Make baconnaise sauce: In a bowl, combine mayonnaise, ketchup, mustard, chopped crispy bacon, Worcestershire sauce, apple cider vinegar, all-purpose seasoning (salt, pepper, garlic), and red pepper flakes. Mix well and refrigerate to allow flavors to meld.
  5. Preheat griddle: Heat your griddle to medium-high and lightly coat with avocado oil to prevent sticking.
  6. Cook burgers: Place the burger balls 2-3 inches apart on the hot griddle. Add sliced onions on top of each ball, then press down firmly with a burger press to smash the patties thin. Season with salt, pepper, and garlic powder.
  7. First side cook: Let the patties cook for 3-4 minutes until a crust forms.
  8. Flip and finish: Spread mustard on the cooked side, then flip the burgers. Immediately top with pepper jack cheese slices and cook another 3 minutes or until cheese is melted and patties are cooked through.
  9. Toast buns: While burgers cook, toast the burger buns on the griddle until golden brown.
  10. Assemble burgers: Spread a generous amount of baconnaise sauce on the bottom bun, add the double smashed burger patties with melted cheese, add more baconnaise sauce on top, and finish with the top bun.

Notes

  • Use 80/20 ground chuck for optimal juiciness and flavor.
  • Chilling the formed patties helps them keep their shape when smashed.
  • Thinly slicing the onions with a mandoline ensures even cooking and softness.
  • Adjust red pepper flakes in baconnaise sauce to your preferred spice level.
  • Avocado oil is chosen for its high smoke point, making it ideal for griddle cooking.
  • Double smash means two thin patties stacked, for extra burger height and flavor.
  • To ensure food safety, cook ground beef patties to an internal temperature of 160°F (71°C).
