Ingredients Method Notes

Ingredients
  

  • 2 tablespoons butter or olive oil
  • 1/2 cup chopped shallots
  • 1/2 cup chopped cremini mushrooms (optional)
  • 2 cloves garlic (minced)
  • 1 head cauliflower (chopped roughly into 2-inch pieces)
  • 2 cups chicken stock (plus more to thin if needed)
  • 1/2 cup raw cashews
  • 1/2 teaspoon tamari (or soy sauce) (optional for more flavor)
  • 1/2 cup parmesan cheese (optional, dairy-free if needed!)
  • salt & pepper to taste

Method
 

  1. Heat butter or olive oil in a medium saucepan over medium-high heat. Add shallots and mushrooms (if using) and cook until softened, 5-7 minutes.
  2. Add minced garlic and cook for 30 seconds until fragrant. Add the chopped cauliflower and chicken stock.
  3. Bring the liquid to a boil, then reduce heat to a simmer, cover, and cook for 10-15 minutes, until cauliflower is very tender.
  4. While cauliflower cooks, place raw cashews in a microwave-safe bowl, cover with water, and microwave on high for 3 minutes to soften. Drain and rinse.
  5. In a high-speed blender, combine the softened cashews with 1/2 cup of water (or chicken stock). Blend until completely smooth and creamy.
  6. Once cauliflower is tender, carefully pour the vegetable mixture into the blender with the cashew cream. Blend on low speed until totally smooth.
  7. Pour the smooth sauce back into the saucepan. Stir in tamari and Parmesan cheese (if using). Season to taste with salt and plenty of freshly cracked pepper. Serve immediately over your favorite pasta!

Notes

– For an even richer sauce, use extra chicken stock or a splash of unsweetened plant-based milk to thin.
– Ensure cauliflower is very tender before blending for the smoothest texture.
– Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.

The technique that makes it

The magic behind this creamy cauliflower alfredo lies in transforming humble cauliflower into a velvety sauce base. The key is to thoroughly cook the cauliflower until it’s exceptionally tender. This is achieved by simmering the cauliflower florets in chicken stock until they are soft enough to be easily pierced with a fork. This process not only softens the vegetable but also infuses it with the savory notes of the stock. Following this, the tender cauliflower, along with the cooking liquid, is blended until completely smooth. The addition of soaked raw cashews further enhances the creaminess and richness, mimicking the texture of traditional dairy-based alfredo. Soaking the cashews (either overnight or in boiling water for 15-30 minutes) is crucial for achieving a silky smooth blend without any grittiness. The final addition of parmesan cheese (if using) provides the characteristic umami and slightly sharp flavor of a classic alfredo sauce.

Troubleshooting

  • Sauce is too thick: Add more chicken stock, a tablespoon at a time, while blending until the desired consistency is reached.
  • Sauce is gritty: Ensure the cauliflower is very tender before blending and that the cashews have been soaked sufficiently. Blend for a longer duration, or use a high-powered blender.
  • Sauce lacks flavor: Increase the salt and pepper. Consider adding a pinch of nutmeg, a squeeze of lemon juice for brightness, or the optional tamari/soy sauce for depth.
  • Sauce is watery: Simmer the blended sauce gently in a saucepan for a few minutes to allow some of the liquid to evaporate, thickening it naturally.

Substitutions

  • Cauliflower: Broccoli can be used, though it will impart a slightly different flavor and a greener hue to the sauce. Ensure it’s cooked until very tender.
  • Chicken Stock: Vegetable stock or water can be used. Using water will result in a less complex flavor, so seasoning becomes even more critical.
  • Raw Cashews: Soaked raw macadamia nuts or blanched slivered almonds can be used. Almonds may require longer soaking and blending for a smooth texture.
  • Parmesan Cheese: Nutritional yeast can be used for a cheesy, umami flavor, especially for a dairy-free or vegan version. The flavor profile will be different but still delicious.

Pro tips

  • For an even richer sauce, use extra chicken stock or a splash of unsweetened plant-based milk to thin.
  • Ensure cauliflower is very tender before blending for the smoothest texture.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.

Frequently asked questions

Can I make this sauce ahead of time?

Yes, this cauliflower alfredo sauce can be made ahead and stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave, adding a splash of stock or water if it has thickened too much.

How do I make this recipe vegan?

To make this recipe vegan, omit the butter and use olive oil. Ensure you skip the optional parmesan cheese or replace it with nutritional yeast for a cheesy flavor. Use vegetable stock instead of chicken stock.

What is the best way to store leftovers?

Store any leftover cauliflower alfredo sauce in an airtight container in the refrigerator. It will keep well for 3 to 4 days. When ready to serve, gently reheat it on the stovetop over low heat or in the microwave.

Can I freeze this cauliflower alfredo sauce?

While it’s best enjoyed fresh, you can freeze the sauce. Place it in a freezer-safe container. The texture might change slightly upon thawing, becoming a bit more watery. You may need to re-blend or simmer it to regain the desired consistency.
