New Zealand Grass-Fed Cheeseburgers with Secret Sauce Recipe

  • Servings: 4-5
  • Prep Time: 20 minutes
  • Cook Time: 15 minutes

Our secret sauce makes this New Zealand grass-fed beef cheeseburger that extra bit tasty and satisfying! We used cheddar, but you can use a different cheese to change up the flavor. Try Camembert, Gruyere or fried haloumi. Blue cheese is an especially delicious match with grass-fed beef.
