Boil a large pot of water and cook your desired pasta according to the package or until al dente.
Add the rest of the ingredients into a high powered blender to make the alfredo sauce.
Blend the dairy-free alfredo sauce until smooth. If it needs to be thinner, keep blending and slowly add small amounts of chicken broth.
Drain the noodles, reserving about ¼ of a cup of pasta water.
Pour the sauce into a pan with half of the reserved pasta water and the noodles. Mix together until the noodles are evenly coated and the sauce is warm. If the sauce is too thick or sticking to the pan, add the rest of the pasta water and mix together.
Notes
Sauce is too thick: Sometimes the sauce is very thick, which is a very easy fix! If you are looking for a thinner sauce, all that needs to be done is adding more chicken broth. Start slow and continue blending until it is your desired texture. If the sauce is too thick once you have it on the pasta, you can use up to a cup of pasta water to help thin it out, again start slow and add more as needed.
Reheating: The sauce will get thicker the longer that it sits with the pasta, so if you are saving leftovers, I always reheat it in a pan with some chicken broth to loosen the sauce again.
High-Powered Blender: If you don't have a high-speed blender (I have a Vitamix), this dairy-free sauce can also be made in a food processor. I do find that a food processor doesn't blend it to completely smooth, but it definitely does the job!
