  • The keto meatballs can be made with beef mince alone if preferred or a combination of beef and veal mince, beef and turkey mince or even the bold flavour of venison mince.
  • For a quicker version of the recipe premade meatballs or marinara sauce then follow the guidelines below to achieve the same great resulting dish.
  • The meatballs are gently combined until they come together naturally, super-tight meatballs become tough and chewy when the ground meat is overworked.
  • Shape the keto meatballs to an even size, they can be as big or small as you like but should be roughly equal to ensure consistent cooking. Smaller meatballs will become dry and larger meatballs will be undercooked.
  • The meatballs can be baked into the oven once they are on the baking tray for 15 minutes rather than browning in the skillet. This method is less effort and clean-up however there is a greater danger of the meatballs drying out.
