Cook your pasta of choice in boiling and well salted water, according to timing of your chosen pastaโs packet directions. Strain & be sure to reserve 1 cup of the starchy pasta water (this is essential).
Place the strained pasta into a bowl. Do not reuse the hot cooking pot for this or you will risk your basil turning from vibrant green to black basil pesto (nowhere near as appealing ๐).
Add your homemade basil pesto as well as approximately 1/3 cup of the reserved pasta water. Continue adding more water as it is required. You want it to be silky smooth.
Taste and adjust the seasoning, according to your tastes.
Serve with additional freshly grated parmesan when serving.
