Slab Sliders

old smokey slab sliders recipe

When you’re feeding a crowd, flipping individual burgers just slows things down. That’s where these Old Smokey Slab Sliders come in.

Instead of shaping patties, you cook one seasoned slab of ground beef right over charcoal, melt the cheese on top, and drop the whole thing onto a toasted sheet of King’s Hawaiian rolls. Slice, serve, and watch them disappear. It’s efficient, forgiving, and exactly the kind of cook that shines on an Old Smokey.

  • Prep Time: 20 Minutes
  • Cook Time: 30 Minutes
  • Servings: This recipe is for a pack of 16 sliders that you can find at Costco. Adjust to 1lb of meat for 12 sliders for a smaller pack of sliders.
Slider Ingredients:
  • 1.3 lbs ground beef (for 16 sliders)
  • Salt, pepper, garlic powder (or your favorite burger seasoning)
  • 4–5 slices American cheese
  • 1 pack (16 rolls) King's Hawaiian Original Sweet Rolls (Costco size)
  • Dill pickles
  • Grilled Onions
Equipment:
  • Old Smokey Charcoal Grill
  • Charcoal
  • Pizza Peel
  • Bowl for Sauce
  • Non-Stick Spray

Prep & Cooking Instructions:

  • Prep and Cook the Meat Slab
    • Form the ground beef into a square slab, roughly the size of the full pack of King's Hawaiian rolls (slightly larger is optimal due to meat shrinking when grilled).
    • Season generously with salt, pepper, garlic powder - you know, the good stuff
    • Cook the slab over charcoal on the Old Smokey
    • I used a pizza peel to flip the slab in one piece. It was crucial (Pam spray before grilling helps to keep from sticking)
    • Once flipped, lay 4–5 slices of American cheese across the slab.
    • While slab is cooking start prepping your rolls
  • Prep the Rolls
    • Slice the entire pack of rolls horizontally so you have one big top and one big bottom (keep them connected).
    • Grill to toast the bottom half lightly—this helps it hold up to the meat, sauce, and juice.
  • Assemble & Serve
    • Place the cooked meat slab directly onto the toasted bottom half of the rolls.
      Add burger sauce, dill pickles and grilled onions
    • Cap it with the top half of the rolls.
    • Slice into individual sliders (16 total).
    • Watch them disappear!

Burger Sauce Ingredients:

  • 2 parts mayonnaise
  • 1 part ketchup
  • 1 part yellow mustard
  • 1 dash Worcestershire sauce
  • 1 spoonful sweet relish
  • A few dashes of Crystal or Louisiana hot sauce (to taste) 

Burger Sauce Instructions:

  • In a bowl, combine mayo, ketchup, and mustard using a 2:1:1 ratio. For example:
    • ½ cup mayo
    • ¼ cup ketchup
    • ¼ cup mustard
    • Add a dash of Worcestershire sauce and a spoonful of sweet relish to taste
    • Stir well until smooth.
    • For an extra bite add Crystal or Louisiana hot sauce or cayenne pepper
    • Chill for 15–30 minutes before serving to let the flavors meld.

Pro-Tip: When making for an event, learn from the expert:  I prepped the burger slabs the night before and wrapped them in parchment paper. Also, I grilled down the onions and made the burger sauce the night before so all we had to do was grill it up and serve the day of.
