Boil pasta, strain and set aside when done cooking. Save 1.5 cups of the cooking water for later!
While pasta is cooking, boil the butternut squash and cashews in a separate pot. Boil until fork tender.
Add cashews and butternut squash to a high-speed blender along with all other ingredients besides the pasta. Blend until completely smooth.
Pour over pasta and enjoy!
Notes
Boil the cashews in with the butternut squash so they soften and blend into a creamy sauce.
Adding in ¼ teaspoon of turmeric is optional but adds some anti-inflammatory benefits and will make the mac and cheese more yellow! (Proceed with caution though; turmeric stains!)
Add more salt to taste as needed.
There may be extra sauce leftover. I use a lot of sauce because I like it extra creamy but feel free to save leftovers for another night!
