30minserves 4




  • Mayonnaise

  • Mustard

  • Ketchup

  • Shredded lettuce

  • Sliced tomatoes

  • Homemade Pickles (and Other Vegetables) (recipe follows)

  • Special Sauce (recipe follows)

  • Caramelized Onions (recipe follows)


  • ½ cup mayonnaise

  • 1 tbsp sweet pickle relish

  • 1 tbsp ketchup

  • 1 tsp Dijon mustard

  • 1 clove garlic, grated

  • ¼ tsp smoked paprika

  • ¼ tsp onion powder

  • Pinch of red pepper flakes

  • Splash of Worcestershire sauce

  • Splash of hot sauce

  • Kosher salt and freshly ground black pepper, to taste

HOMEMADE PICKLES (and other vegetables):

  • 1 ¼ cups water

  • ¾ cup rice vinegar

  • 1 tsp kosher salt

  • 1 tsp sugar

  • 2 tsp pickling spice

  • ½ tsp red pepper flakes

  • 1 pound Persian cucumbers, sliced into coins or spears (you could also use this for carrots + jalapeños + green beans + cauliflower)

  • 6 large sprigs dill

  • 3 cloves garlic, smashed and peeled


  • 2 tbsp Tillamook Extra Creamy Unsalted Butter

  • 3 tbsp olive oil, divided

  • 2 large yellow onions (about 1 pound), peeled and sliced ¼ inch thick
    Kosher salt and freshly cracked black pepper

  • 1 tsp fresh thyme leaves



  1. Using a box grater, grate the frozen stick of butter on the smallest size holes.

  2. Combine the beef, grated butter, salt, pepper, and garlic powder in a large bowl. Don’t overmix.

  3. Divide into 8 portions and loosely form into balls, about 4 ounces for each. Cover with plastic wrap and set aside.

  4. Preheat a gas or charcoal grill to high heat (450ºF to 500ºF/230ºC to 260ºC) with a cast-iron griddle on it. You want it smoking hot.

  5. Split the buns and slather with mayonnaise on each cut side.

  6. Toast the burger buns on the hot griddle for 1 to 2 minutes, until golden, making sure not to burn them. Remove from the heat.

  7. Working quickly, place 4 of the burger balls on the griddle on the grill and, using a piece of parchment paper just bigger than the final patty size and a spatula, smash the ball into a thin burger. You want to really put some weight into it to make it as thin as possible. You can even use another metal spatula to assist in the smash. Slide the spatula off (don’t pull it up). This will help the patty stay flat against the griddle.

  8. Cook for 3 to 4 minutes; at the end, add a few slices of onion, then quickly flip the patties and give them another smash with the spatula.

  9. Top each patty with sliced cheese, close the lid on the grill, and cook another 3 to 4 minutes, until the cheese is melted.

  10. Stack 2 patties and place them on the bottom bun. Top with desired toppings (see below for instructions on how to make the homemade pickles, caramelized onions and special sauce) and the top bun.
