For the Burger

  • 1 lb ground beef
  • 4 hamburger buns
  • 8 slices of tomato
  • 1 finely chopped white onion
  • 8 pickle slices
  • 8 lettuce leaves
  • 2 tsp salt
  • 2 tsp ground pepper

For the Sauce

  • 4 tbsp mayonnaise
  • 1/2 tsp lemon juice
  • 1 tsp onion powder
  • dash of sugar


For the Sauce

  • Simply mix all of the sauce ingredients into a bowl. Cover the bowl and place it in the refrigerator at least one hour before serving.

For the Burger

  • First, preheat an electric griddle to 400 degrees. Toast your buns by laying them face down on the griddle for about a minute, and set aside.
  • Form the ground beef into thin patties, slightly larger than the bun. Cook patties on the hot griddle for 2 to 3 min per side. Pinch a bit of salt and pepper and sprinkle it over each patty.
  • Once the patties have cooked, it's time to assemble the burgers. ┬áTake the bottom bun and spread the sauce over it. Then stack the ingredients in the following order: 1 beef patty, 2 tomato slices, 2 lettuce leaves, 2 pickles, a handful of diced onions, and top bun. Serve hot and enjoy.


  • If you'd like to turn this into a Jumbo Jack Cheeseburger, simply sandwich your meat patty between two slices of American cheese.
  • Double the amount of meat if you want to make a Double Jack.
