Zucchini Noodles

  • Tip and tail your zucchini and depending on the spiralizer you have you may need to cut zucchini into a manageable size. Following the instructions create desired amount of zoodles. I large (350g) zucchini will generally yield 2 servings of pasta noodles

  • Assemble your low carb spaghetti and meatballs and garnish with red chili flakes, fresh basil, fresh parsley, fresh grated cheese, or Parmesan cheese

As always, check the post above the recipe for more details and tip on how to make this recipe
Meatball Tips:
  • Allow you ground meat to come to near room temperature to avoid painfully numb hands
  • Protein: You can definitely try any ground meats you would like for this recipes
  • Higher fat content ground beef will help keep the meatballs from falling apart during cooking
  • You should not need to use any binder to keep these together, but if you do, use some dried Parmesan cheese as a low carb breadcrumb replacement
  • Fresh is better, but pre-chopped frozen onions and minced garlic are a convenient timesavers
Sauce Tips:
  • Store leftovers in a sealed container of jar in the fridge
  • Letting your sauce simmer longer will soften onions and garlic further and allow the flavours to develop
