Behind the Recipe

Burgers on an Oakford

If there's any other way to braai smash burgers without using the Oakford 790 Pellet Grill and still call the end-product a perfect animal style burger, then we need to know.

According to legend, animal style burgers derive their name from the local surfers and skaters who would order their mustard-grilled smash burgers and sauce, boisterously devouring them like animals. With no shame in the name, the animal style burger deserves its lip-smacking, face-wiping enjoyment wherever it's made. 

Again, we suggest making them the 'perfect way' by smashing those patties on your Pellet grill. 



  • 2 tablespoons of vegetable oil, plus more for brushing
  • 2 large onions, finely chopped
  • Kosher salt
  • ¼  cup of mayonnaise
  • 2 tablespoons of tomato sauce
  • 1 tablespoon of sweet pickle relish
  • ½  teaspoon of white vinegar
  • 2 pounds of ground beef chuck 
  • 4 hamburger buns, split
  • ¼  cup of sliced dill pickles
  • ¾ cup of shredded iceberg lettuce
  • 4 to 8 thin slices of tomato
  • Freshly ground pepper
  • ¼  cup of yellow mustard
  • 8 slices of American cheese


  1. Using your Nexgrill App set the Pellet grill to the smoke cooking method at 180°C which is the medium-high heat that you need.
  2. Prepare your ground beef by rolling them into balls 
  3. Slice open some burger buns 

Cooking Instructions

  1. 1

    Heat the vegetable oil in a large skillet over medium-low heat. Add onions and a 3/4 teaspoon of salt, cover and cook until golden and soft, which should take about 30 minutes. Add ½ a cup of water to the skillet, scraping up the browned bits from the bottom. Simmer until the water evaporates, about 2 more minutes; transfer to a bowl.

  2. 2

    Mix the mayonnaise, relish tomato sauce, and vinegar in a bowl. Squash the beef into patties, about 10 cm wide and about 2 cm thick.

  3. 3

    Then toast the buns on your pellet grill. Spread each bun bottom with 1 tablespoon of the mayonnaise mix, then top with pickles, lettuce, 2 slices of tomato and some more of the mayonnaise mix.

  4. 4

    Season the patties with salt and pepper. Place the patties on the pellet grill and cook for approximately 3 minutes. Spread 1 and a half teaspoons of mustard on the side of each patty that is uncooked, flip and top with 1 slice of cheese; continue cooking about 2 more minutes till medium rare. Top the patties with caramelized onions, cheese-side up. Sandwich the double patties on the buns.
