Vegan Pesto Pasta (with Thai basil)

This pasta recipe is unbelievably easy to make, and so delicious. Thai basil is known for its antioxidants. It’s anti-cancer, anti-viral, anti-bacterial, and anti-fungal properties make it a healing herb. In addition to that, Thai basil aroma is traditionally used to help relieve stress.

Thai basil is slightly different from Italian basil (sweet basil). It’s more pungent and has got more of a licorice, peppery, star anise note to it than sweet basil. Although they may look quite similar, the most distinguishable feature between Thai basil and Italian basil are the stems. Thai basil has a purple stained stem, and Italian basil has a light green stem.

Why Thai basil and not Italian basil?

Of course, nothing beats the classic Italian sweet basil pesto, but Thai basil adds a Southeast Asian element to pesto that delivers more spice and aroma than the delicate, traditional flavours of pesto. I have also made this vegan, so I have substituted parmesan with nutritional yeast. This substitute also contributes to the more peppery texture than a diluted creamy texture.
