Brussel Sprout Sauce Recipe: Creamy, Garlicky Drizzle for Any Dish

This creamy, garlicky sauce transforms even the simplest Brussels sprouts into a restaurant-worthy dish. Developed through careful testing, it balances rich creaminess with bright garlic and subtle acidity for perfect flavor harmony. The velvety texture clings beautifully to roasted vegetables while adding depth to any meal.

Versatile beyond Brussels sprouts, this sauce works equally well as a dip for crudités or a drizzle over grilled proteins. Its simple ingredients come together quickly, and the consistency can be easily adjusted with a splash of water or additional cream. Store in an airtight container for up to five days, maintaining its fresh, vibrant flavor.

Ingredients for Brussel Sprout Sauce

Nine plant-based ingredients create this velvety, restaurant-quality sauce with balanced creaminess and garlic depth.

The cashews are critical for texture—raw and unsalted is non-negotiable. Trader Joe’s or bulk bins at natural food stores offer the best value. Soak them in boiling water for 15 minutes to soften; this ensures a silky-smooth blend without grit. Nutritional yeast provides the cheesy undertone; Bragg or Bob’s Red Mill brands deliver consistent quality. For garlic, fresh cloves are essential—pre-minced lacks the necessary sharpness and aroma.

No cashews? Raw sunflower seeds or silken tofu work as substitutes, though the flavor profile shifts slightly. Out of nutritional yeast? White miso paste (1 tbsp) adds similar umami depth. The Dijon mustard can be replaced with yellow mustard plus a pinch of turmeric for color. For acidity adjustments, rice vinegar or white wine vinegar can stand in for apple cider vinegar. Always taste before final seasoning—salt levels vary by brand.

This sauce maintains its velvety texture for 5 days refrigerated in an airtight container. The surface may thicken; stir in 1-2 tbsp water to restore consistency. Freezing is possible for up to 3 months, though texture may separate slightly upon thawing—re-blend with a splash of plant milk to revive. For optimal flavor, use within 48 hours when the garlic is most vibrant.

Step-by-Step Instructions for Creamy Brussel Sprout Sauce

This straightforward method transforms simple ingredients into a velvety, garlicky sauce with perfect balance.

Step 1: Prepare the Cashew Base

Begin by draining the soaked 1 cup raw cashews completely. I press them gently between paper towels to remove all excess moisture—this ensures your sauce will be perfectly smooth rather than watery. The cashews should feel soft and pliable after their 15-minute hot water soak, indicating they’re ready to blend.

Transfer the drained cashews to a high-powered blender. Add the 0.5 cup water and blend on high for 1-2 minutes until completely smooth. You’re looking for a thick, creamy consistency similar to heavy cream. Stop occasionally to scrape down the sides with a spatula, ensuring no cashew pieces remain unblended.

Step 2: Build the Flavor Foundation

To the cashew mixture, add the 6 cloves garlic cloves (roughly chopped), 3 tbsp lemon juice, 2 tbsp nutritional yeast, 1 tbsp Dijon mustard, and 1 tbsp apple cider vinegar. Blend again for 30-45 seconds until all ingredients are fully incorporated. The mixture should become pale yellow and develop a slightly frothy top.

The garlic will be completely puréed, while the nutritional yeast dissolves to create that distinctive cheesy undertone. Taste at this stage—you should detect a bright acidity from the lemon and vinegar balanced by the mustard’s subtle heat. If the mixture seems too thick, add water 1 tablespoon at a time until it reaches your desired consistency.

Step 3: Season and Perfect the Texture

With the blender running on low speed, add the 0.75 tsp sea salt and 0.25 tsp black pepper. Blend for an additional 20-30 seconds until the seasoning is evenly distributed. The sauce should now have a smooth, pourable consistency that coats the back of a spoon.

For the creamiest texture, I let the sauce rest for 5 minutes after blending. This allows any air bubbles to dissipate and the flavors to meld. Give it one final pulse if needed to achieve that luxurious, velvety finish. The color should be a warm ivory with no visible specks of garlic or nutritional yeast.

Step 4: Adjust and Serve

Transfer the sauce to a small saucepan and warm over low heat for 3-5 minutes, stirring constantly. This gentle heating enhances the flavors without risking separation. The sauce should reach a temperature where it’s warm to the touch but not simmering—about 110°F if you’re using a thermometer.

Taste and adjust seasoning if needed. The sauce should have a balanced profile: creamy richness from the cashews, bright acidity, garlicky depth, and a subtle cheesy note from the nutritional yeast. For a thinner consistency, whisk in additional water 1 teaspoon at a time. Serve immediately while warm for the best texture and flavor.

Flavor Customization for These Flavors

Extra Garlicky Kick

For garlic lovers, double the garlic to 12 cloves and roast them first. Toss whole peeled cloves with 1 tsp olive oil and roast at 400°F for 15 minutes until golden. The caramelized notes add incredible depth while mellowing the sharpness. I do this when serving with grilled meats or hearty vegetables. 🧄

Spicy Sriracha Twist

Add 1-2 tbsp sriracha when blending for a fiery kick that pairs perfectly with roasted Brussels sprouts. The heat balances beautifully with the creamy base. For smoky depth, use chipotle powder (½ tsp) instead. I love this variation with blackened tofu or spicy tacos.

Herb-Infused Brightness

Blend in ¼ cup fresh basil or 2 tbsp fresh dill at the very end for vibrant color and aroma. Basil adds sweetness that complements roasted veggies, while dill creates a refreshing contrast. I use this version as a dip for spring vegetable platters.

Smoky Chipotle Depth

For a barbecue-inspired sauce, add 1-2 canned chipotle peppers in adobo (seeds removed) plus 1 tsp smoked paprika. The smokiness works wonderfully with grilled Brussels sprouts or as a burger topping. I discovered this combo at a Texas food festival.

Citrus Variation

Replace the lemon juice with 3 tbsp orange juice and add 1 tsp orange zest for a brighter, sweeter profile. This pairs beautifully with roasted carrots or as a seafood sauce. The citrus notes make it feel lighter while keeping the creamy texture.

Nut-Free Alternative

Swap cashews for 1 cup cooked cauliflower florets plus 2 tbsp tahini for a nut-free version. The texture will be slightly less creamy but still delicious. I developed this for friends with nut allergies—it’s become a favorite for school lunches. ✨
