Instructions
- 1
Soak cashews in very hot water for 30 minutes, uncovered.
- 2
Bring 3 quarts water with 1 Tbsp salt to a boil in a large pot. Add pasta, stir, and cook to the lower end of package al dente time.
- 3
While pasta cooks, blend soaked cashews, lemon zest, lemon juice, garlic powder, garlic clove, chickpea miso, nutritional yeast, salt, and olive oil with 1 cup water until completely smooth, about 1 minute.
- 4
Transfer blended sauce to a large shallow pan at least 10 inches in diameter and 3 inches deep.
- 5
Test pasta for doneness when it should be slightly firmer than desired. Reserve 1 cup pasta water, then drain pasta.
- 6
Off heat, whisk 1/2 cup reserved pasta water into the sauce. Add drained pasta.
- 7
Heat to medium low and stir constantly for 3-5 minutes until sauce thickens and clings to pasta.
- 8

Tips
Reserve pasta water before draining. The starch is essential for sauce emulsification and achieving that signature cling to the pasta.
Taste the raw sauce before it hits the pasta. It should taste quite tart from lemon and savory from garlic. This balance adjusts as you toss.
Cook pasta to the firmer end of al dente. It finishes cooking directly in the sauce over medium-low heat for 3-5 minutes.
Good to Know
Transfer leftovers to an airtight container and refrigerate up to 5 days. The sauce will stiffen as it cools. Reheat in a skillet over medium-low heat with a splash of non-dairy milk to restore creaminess. Stir frequently.
Soak cashews up to 24 hours ahead. Blend sauce up to 1 day in advance and store in an airtight container. Cook pasta fresh.
Serve immediately for best texture. The sauce is most fluid and luxurious when just tossed. Garnish each plate with fresh parsley, red pepper flakes, and extra vegan parmesan.
Common Mistakes
Do not skip reserved pasta water. Adding it gradually allows the sauce to emulsify and coat the pasta rather than remain thin and separate.
Do not cook pasta to full al dente before the pan. It will overcook while tossing in the sauce.
Do not freeze. Cashew-based sauces separate and become grainy when thawed.

FAQ
Can I make this sauce ahead?
Yes, blend the sauce up to 1 day ahead and store in an airtight container in the refrigerator. Whisk with reserved pasta water just before tossing with hot pasta. The emulsification happens fresh in the pan.
What if my sauce looks too thin after blending?
This is correct. The sauce should resemble non-dairy milk in consistency. It will thicken as you toss it with hot pasta and pasta water over medium-low heat for 3-5 minutes. Trust the process.
How long will leftovers keep and can I freeze them?
Refrigerate up to 5 days in an airtight container. Do not freeze; cashew cream separates and becomes grainy upon thawing. Reheat gently in a skillet with a splash of non-dairy milk to restore creaminess.
