Kelp noodles play well in any dish. It has no distinct flavor or aroma so it lends well to pasta dishes. Don’t let the name fool you, there is no fishy taste to this ingredient. Just good for you minerals & vitamins to compliment a fresh garlic & basil pesto.

Kelp Noodle Pasta

  • 1 package kelp noodles
  • 3-4 cups hot water (or enough to cover noodles in a bowl)
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • Juice of ½ lemon or 2 Tablespoons apple cider vinegar or white vinegar

Add all the ingredients to a large bowl and let sit for 10-15 min. Mix it a bit by hand to separate the noodles. Once they’re as soft as you want, strain and rinse them well. Drain and mix with sauce. Or place them in the fridge for quick assembly later. They’ll keep well at least 2 days.


  • 1 small shallot, sliced thin on a mandolin (this is the one I use & it’s the BEST!)
  • 1/4 organic red bell pepper, sliced thin on a mandolin

Slice the shallot & bell pepper on the mandolin slicer. Use a paper towel to soak up any excess liquid from the sliced bell pepper. This will ensure your pasta isn’t watered down.

Marinated Mushrooms

Rinse, pat dry, and chop or slice the mushrooms. Add the coconut aminos (or soy sauce alternative), lemon juice, & olive oil. Mix to combine, cover, & set aside while you prepare the rest of the ingredients.

Pesto Sauce

Make the Pesto sauce by adding all ingredients to a tall cup and emulsifying with a hand blender like this one. Or you can use your Vitamix. (*Tip: If you double the pesto recipe – careful with the salt and lemon – this will blend easier in your blender, as you need more volume for the blades to puree the ingredients). Store the extra in the freezer for quick prep next time you make the dish.

To serve, toss the kelp noodles in a generous amount of the pesto sauce and garnish with marinated veggies, mushrooms and grated macadamia nut on top.
