  • 2 lbs Ground Beef 85/15
  • 1.5 tbsp Kosher Salt
  • 1.5 tbsp Black Pepper
  • 1.5 tbsp Garlic Powder
  • Yellow Mustard as needed

Burger Sauce:

  • ½ cup Mayonnaise
  • ½ cup Ketchup
  • 2.5 tbsp Relish
  • 2 tbsp White Vinegar
  • 1 tbsp FYR RED Hot Sauce


  • 3-4 Yellow Onions
  • Sliced American Cheese
  • Cooked Fries/Tater Tots serving
  • Beef Tallow as needed


  • In a bowl, mix all the ingredients for the special sauce then place in the fridge until ready to use.
  • Slice your onions into 1” thick onion slices as a whole to use as your “buns”.
  • Heat your grill to high heat (around 450 degrees F) for direct cooking.
  • Grab a handful of ground beef (around 1/4 lbs… ish) and gently roll it into a ball. Repeat this for 6-8 balls or until you’re out of meat.
  • Add a cast iron skillet or plancha over the flames to heat till it's slightly smoking (about 450 on the skillet).
  • Add a burger ball to the skillet. Place a piece of parchment over one ball and then firmly press with the spatula until the burger is “smashed” on the skillet.
  • Season the patty with salt, pepper, and garlic. Let cook for another 1-1.5 minutes. Before flipping, drizzle some yellow mustard on the unflipped patty.
  • Carefully flip the burger patty over and then season the new side. Top with a slice of cheese and let melt for 1-2 minutes.
  • Once melted, pull off and rest. Repeat for the rest of your patties.
  • Add your sliced onions to cook for 2 minutes per side. Once browned, top with a slice of cheese and let melt.
  • Build your burger with onion slice, burger sauce, smash burgers, more sauce and another onion slice. Serve and enjoy!
