Ingredients

• 1 medium head cauliflower (about 4 cups chopped)
• 1/2 cup raw cashews (soaked for 2 hours or boiled for 10 minutes)
• 2 cups unsweetened almond milk (or your favorite plant milk)
• 3 cloves garlic (minced)
• 1/4 cup nutritional yeast (for cheesy flavor)
• 1 tablespoon lemon juice (freshly squeezed)
• 1 teaspoon Dijon mustard
• 1/2 teaspoon onion powder
• Salt & black pepper to taste
• Optional: pinch of nutmeg for warmth and depth
• Optional garnish: fresh parsley or basil

Equipment

• Large saucepan or pot
• Blender or high-speed food processor
• Knife and cutting board
• Measuring cups and spoons
• Colander or strainer (for draining cashews and cauliflower)
• Wooden spoon or spatula

Instructions

1. Prepare the cauliflower: Wash and chop the cauliflower into small florets. Steam or boil the cauliflower until very tender, about 8-10 minutes. Drain and set aside.
2. Soak the cashews: For best creaminess, soak cashews in hot water for 2 hours or boil them for 10 minutes if short on time. Drain before using.
3. Sauté the garlic: In a dry skillet over medium heat, lightly toast minced garlic for 1-2 minutes until fragrant, being careful not to burn it. This step enhances the garlic’s flavor.
4. Blend the sauce: In a blender, combine cooked cauliflower, soaked cashews, toasted garlic, almond milk, nutritional yeast, lemon juice, Dijon mustard, onion powder, and a pinch of nutmeg (if using). Blend on high until smooth and creamy.
5. Season: Taste the sauce and add salt and black pepper as needed. Blend again briefly to mix.
6. Heat the sauce: Pour the blended sauce back into the saucepan and warm over low heat for 3-5 minutes, stirring occasionally. Do not boil—just heat through.
7. Serve immediately: Toss with cooked pasta, drizzle over steamed vegetables, or use as a dip. Garnish with fresh parsley or basil if desired.

Tips & Variations

“For an ultra-smooth sauce, strain the blended sauce through a fine mesh sieve before heating.”

• Make it gluten-free: Serve with gluten-free pasta or spiralized veggies.
• Add herbs: Fresh thyme, basil, or oregano can be blended in for extra flavor.
• Spicy kick: Add red pepper flakes or a dash of cayenne pepper.
• Lower fat: Reduce cashews by half and increase cauliflower for an even lighter sauce.
• Cheesy boost: Add a tablespoon of vegan parmesan or extra nutritional yeast.
• Storage: Store leftovers in an airtight container in the fridge for up to 4 days or freeze for up to 1 month.
