Ingredients

• 1½ pounds / 680g (24 oz) fresh cauliflower florets
• 2 cups / 475ml chicken stock or bone broth
• 4 cloves garlic, peeled
• ½ cup / 120ml (4.1 fl oz) unsweetened almond or coconut milk
• 2 tablespoons / 30ml (1 fl oz) bacon drippings
• 1 tablespoon nutritional yeast
• 1 tablespoon (15 ml / 0.5 fl oz) chopped fresh flat-leaf parsley
• 1½ teaspoons sea salt
• ½ teaspoon ground black pepper
• 1 tablespoon (15 ml / 0.5 fl oz) fish sauce or gluten-free soy sauce

Instructions

1. Directions
2. In a large saucepan, combine the cauliflower florets, chicken stock, and whole garlic cloves. Cover the pan and bring to a boil over medium-high heat.
3. Once boiling, reduce the heat to medium and let it simmer for about 10 minutes, or until the cauliflower is tender enough to be easily pierced with a fork.
4. Carefully transfer the entire contents of the saucepan—cauliflower, garlic, and any remaining stock—to a high-powered blender or food processor. Add the almond milk, bacon drippings, nutritional yeast, parsley, salt, pepper, and fish sauce.
5. Blend on high until the mixture is completely smooth and creamy. You may need to scrape down the sides once or twice to ensure everything is incorporated.
6. Pour the blended sauce back into the saucepan and warm it over medium heat for about 5 minutes, stirring occasionally. This step helps the flavors meld together beautifully. Serve immediately.

Frequently Asked Questions

Is cauliflower Alfredo sauce keto?

Per ¼-cup serving it has 3.2 g total carbs with 1.2 g fiber, about 2 g net carbs. It is one of the lighter Alfredo options and pairs perfectly with zucchini noodles.

Can I make this sauce vegan?

Yes — use vegetable broth instead of chicken stock and swap the bacon drippings for olive oil or vegan butter. The fish sauce step would also need a plant-based alternative.
