# What You'll Need:

→ Smash Burgers

01 - 2 pounds ground chuck (80/20), formed into six 1/3 pound balls
02 - 2 white onions, thinly sliced
03 - 1/2 pound bacon, cooked until crisp and chopped
04 - Salt, freshly ground black pepper, and granulated garlic for seasoning
05 - Yellow mustard, for cooking
06 - 6 slices pepper jack cheese
07 - 6 burger buns, split and toasted
08 - Avocado oil, for greasing the griddle

→ Baconnaise Sauce

09 - 1/2 cup mayonnaise
10 - 2 tablespoons ketchup
11 - 2 tablespoons yellow mustard
12 - 1/2 pound bacon, cooked until crisp and finely chopped
13 - 1 tablespoon Worcestershire sauce
14 - 1 tablespoon apple cider vinegar
15 - 1 tablespoon all-purpose seasoning blend (salt, pepper, granulated garlic)
16 - 1 tablespoon red pepper flakes

# Directions:

01 - Form ground chuck into six 1/3 pound balls and refrigerate for 30 minutes to set the shape.
02 - Thinly slice white onions using a mandoline for even thickness, blot dry with paper towels, and refrigerate until use.
03 - In a mixing bowl, combine mayonnaise, ketchup, yellow mustard, finely chopped cooked bacon, Worcestershire sauce, apple cider vinegar, all-purpose seasoning, and red pepper flakes. Mix thoroughly and refrigerate for optimal flavor.
04 - Cook bacon in a skillet over medium heat until crisp. Drain excess fat, chop finely, and divide for sauce and burger topping.
05 - Preheat a flat griddle over medium-high heat and apply a thin, even layer of avocado oil.
06 - Place each burger ball on the hot griddle. Top with a portion of sliced onion and smash with a burger press to ensure contact. Season with salt, ground black pepper, and granulated garlic.
07 - Brush the exposed side of patties with yellow mustard. After 3–4 minutes, flip patties, immediately top with pepper jack cheese, and continue cooking for 3 minutes until cheese has melted.
08 - While burgers finish, toast the cut sides of buns on the griddle until golden brown.
09 - Spread Baconnaise sauce on the bottom half of each toasted bun, stack two cheeseburger patties, top with additional sauce, and finish with the upper bun. Serve immediately.

# Notes:

01 - Chilling the meat balls before smashing helps maintain a juicy interior during searing.
