Prep: 10 minsCook: 20 minsTotal: 30 mins
Servings: 8 1x


  • Hamburgers:
  • 1 lb. grass-fed ground beef
  • 1/2 onion, finely chopped
  • 34 garlic cloves, minced
  • 1/2 cup grated Parmesan cheese
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon ketchup
  • 1 egg
  • salt and pepper
  • Toppings:
  • 1/2 onion, sliced
  • 1 tablespoon butter (for caramelizing the onions)
  • 1 slicing tomato
  • 1/2 avocado, sliced
  • 8 leaves green leaf lettuce
  • Special Sauce:
  • 3 tablespoons mayo
  • 2 tablespoons ketchup
  • 1/2 teaspoon garlic powder
  • dash hot sauce (about 1/8 teaspoon)
  • dash liquid smoke (about 1/8 teaspoon)


  1. In a bowl, combine the ground beef, 1/2 of the onion (chop it), minced garlic, Parmesan, Worcestershire, ketchup, egg, salt, and pepper.
  2. Use your hands to combine all the ingredients and mix everything together.
  3. Form the meat mixture into patties. I made smaller slider patties (about 8) so they were easily wrap-able in the lettuce.
  4. Optional step: spray (or brush) each side of the hamburgers with oil or ghee.
  5. Heat your grill on high for 5 – 10 minutes.
  6. Then turn down the heat to medium and place the burgers on the grill.
  7. Grill each side for about 5 minutes, until they are easily flippable and don’t stick when you try to slide the spatula under.
  8. While you’re cooking the hamburgers, or waiting for the grill to heat up, slice the other half of the onion and place it in a pan over medium heat with 1 tablespoon butter or oil.
  9. Cook, stirring occasionally for about 10 minutes to caramelize the onions.
  10. For the special sauce, in a small bowl, whisk together the mayo, ketchup, garlic powder, hot sauce, and liquid smoke.
  11. Place a slice of tomato in the middle of the leaf, followed by some avocado, the burger, caramelized onion, and some special sauce.
  12. Fold up the sides and secure with a couple toothpicks.
  13. These are best and juiciest right off the grill, so enjoy immediately. OMG, salivating.
