Prep
Soak cashews in hot water for 20 minutes, then drain.
Cook pasta in well-salted water according to package directions.
Reserve ½ cup pasta water, then drain.
Stovetop & Blending Method
Heat olive oil in a large skillet over medium heat.
Add onion and sauté 3–4 minutes until soft.
Add garlic and cook 30 seconds until fragrant.
In a blender, combine cashews, plant milk, nutritional yeast, lemon juice, salt, pepper, and paprika.
Blend until completely smooth and creamy.
Pour sauce into the skillet and simmer on low heat 3–5 minutes, stirring often.
Add cooked pasta and toss to coat, adding pasta water or broth a little at a time to loosen.
Texture Check
Sauce should be thick and silky, clinging to the pasta.
Too thick? Add liquid gradually.
Too thin? Simmer gently another minute.
Finish
Remove from heat and rest 2 minutes. Adjust seasoning and garnish with herbs or vegan parmesan if desired.
