- Soak cashews in hot water for 10-15 minutes (or longer if not using a high-powered blender).
- Heat olive oil in a pan over medium heat. Sauté onion for 5 minutes, then add garlic and Italian seasoning, cooking for 1 more minute.
- Cook pasta al dente according to package instructions. Reserve some pasta water before draining.
- In a high-speed blender, combine sautéed onion and garlic, soaked cashews, nutritional yeast, lemon juice, salt, and reserved pasta water. Blend until smooth, adding more water if needed.
- Pour sauce over pasta, toss to coat, and serve immediately.
Notes
- Store leftover sauce in an airtight container in the fridge for up to 4–5 days. It may thicken, so stir in a splash of water when reheating.
- For freezing, keep the sauce separate from the pasta. Freeze in containers with space to expand.
- Avoid roasted or salted cashews for the best flavor and texture.
- Thin the sauce with more pasta water or a splash of plant-based milk if needed.
- No high-speed blender? Soak cashews at least 2 hours or overnight for extra creaminess.
- For a nut-free version, use raw sunflower seeds instead of cashews. It’ll still be creamy, but the taste will be a bit different.
