What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Soak cashews in boiling water for exactly 10 minutes — over-soaking can make them waterlogged and thin the sauce.
- 2Reserve a full cup of pasta water; the starch helps emulsify the sauce and gives it a silky cling.
- 3Blend the cashew cream for a full 90 seconds to break down all particles — a high-speed blender yields the smoothest result.
- 4Warm the sauce over low heat only; high heat can cause cashew cream to curdle or separate.
- 5For a nuttier flavor, toast the cashews in a dry pan for 2-3 minutes before soaking.
- 6Add the reserved pasta water gradually, 1 tablespoon at a time, to control the sauce thickness without making it runny.
Adapt it for your goals.
Oil-free
Skip the olive oil and water-sauté the onion and garlic in a few tablespoons of vegetable broth. The cashew cream still provides enough richness for a satisfying sauce.

Sauté 200g sliced cremini mushrooms with the onion and add 1/2 teaspoon smoked paprika to the blender. This adds an earthy, savory depth for a heartier pasta dish.

Add 1/4 cup oil-packed sun-dried tomatoes (drained) to the blender along with the cashew cream. It brings a sweet-tangy pop and a gorgeous rosy color.

Stir in 2 tablespoons of hemp seeds or a scoop of unflavored pea protein powder into the blender. This boosts protein without altering the creamy texture.
