- Prep and Roast:
Preheat your oven to 390°F (200°C). Place the cauliflower and garlic on a lined baking sheet or roasting pan. Drizzle with 1 tablespoon of olive oil, sprinkle with salt and vegetable stock powder, and toss to coat. Roast for 30 minutes, or until the cauliflower is golden and easily pierced with a fork. - Soak the Cashews:
While the cauliflower roasts, pour boiling water over the cashews in a heatproof bowl. Cover and let soak for 20 minutes (or soak overnight for a creamier consistency). Drain and rinse with cool water. - Blend the Sauce:
Once the cauliflower is ready, allow it to cool slightly. In a high-speed blender, combine the roasted cauliflower, garlic, soaked cashews, almond milk, remaining olive oil, nutritional yeast, lemon juice, and a pinch of nutmeg. Blend until smooth, adding more almond milk for a thinner consistency if desired. Season to taste with salt and pepper. - Serve:
Pour the sauce over your pasta of choice, toss to coat, and garnish with fresh parsley. Enjoy your creamy, dairy-free Alfredo!
Substitutions

- Garlic: Use garlic powder (1 teaspoon per clove) or shallots for a milder flavor.
- Olive Oil: Replace with avocado oil, coconut oil, or melted vegan butter.
- Vegetable Stock Powder (or Vegeta seasoning): Substitute with miso paste (½ teaspoon per teaspoon of powder) for a savory depth or onion powder and salt.
- Raw Cashews: silken tofu for a similar creamy texture.
- Almond Milk (or preferred milk substitute): Use coconut milk, oat milk, or cashew milk for creaminess.
- Nutritional Yeast: dairy-free Parmesan for a cheesy taste.

Storage
Store any leftover dairy-free Alfredo sauce in an airtight container in the refrigerator for up to 2-3 days. Reheat gently on the stove or in the microwave, adding a splash of almond milk or water to reach your desired consistency. Freezing is not recommended as it may affect the texture.
Top tips
- Roast Cauliflower Well: Roast until golden and tender; this adds depth and richness to the sauce.
- Blend Cashews Smooth: Ensure cashews are well-soaked and blend until completely smooth for a creamy, lump-free sauce.
- Adjust Consistency: Add almond milk gradually when blending to achieve your preferred sauce thickness without thinning it too much.
FAQs
Fettuccine or linguine are classics, but any pasta will work! Try it with spiral or tube-shaped pasta to capture more sauce in each bite.
Freezing isn’t ideal, as it may affect the sauce’s creamy texture. Fresh is best, but if you must, freeze in a tightly sealed container for up to 1 month and blend again after thawing.
Absolutely! Make the sauce up to 3 days in advance and store it in the fridge. Reheat with a little extra almond milk or water to refresh the creamy texture before serving.
