Ajo Blanco Sauce Recipe: Chilled Celery-Cream Velocity With Vinegar Zing

This ajo blanco sauce recipe delivers the crisp, chilled elegance of Andalusian cuisine with just five simple ingredients. The secret lies in blending toasted almonds and stale bread into a velvety base, then brightening it with sherry vinegar and garlic-infused olive oil.

What makes this sauce extraordinary is its perfect balance—creamy yet refreshing, with just enough acidity to cut through rich cold meats.

The traditional method calls for blending raw garlic with the other ingredients, but I've perfected a gentler approach by infusing the olive oil first. This eliminates harsh garlic flavors while preserving that signature ajo blanco aroma.

The sauce thickens beautifully when chilled, creating an ideal dipping vehicle for cured ham, smoked fish, or even fresh crusty bread.

What you'll end up with is a silky, pale green sauce that's cool and comforting—perfect for hot summer days or festive tapas gatherings. The texture transforms from slightly thick to perfectly pourable when refrigerated, making it ideal for drizzling over salads or serving alongside charcuterie boards.

Storage is effortless: simply transfer to an airtight container and keep refrigerated for up to 5 days.

For a modern twist, consider adding finely diced cucumber or a splash of lemon juice to enhance the refreshing quality. The sauce also works beautifully as a base for chilled soups or as a marinade for grilled vegetables. Let's create this Andalusian classic that's as versatile as it is delicious.

Ingredients for ajo blanco sauce

Five ingredients transform into Andalusian ajo blanco's signature creamy-chilled elegance.

The celery and almonds form the sauce's velvety foundation. Fresh celery from the produce section—look for crisp, pale stalks with no brown spots—works best, but frozen will do in a pinch. For almonds, Trader Joe's or bulk bins offer the best price per pound, and skin-on varieties add subtle texture. The bread? Stale crusty loaves (like sourdough or baguettes) soak up liquid beautifully—toss any moldy pieces. Garlic matters here too: Spanish garlic has a milder, sweeter profile that pairs perfectly with sherry vinegar.

No sherry vinegar? White wine vinegar or apple cider vinegar work in a bind, though the flavor will be slightly different. Want extra creaminess? Blend in 2 tablespoons tahini or silken tofu with the base. The olive oil infusion is key—toast the garlic cloves in a dry pan for 30 seconds before infusing to mellow their sharpness. For a modern twist, add 1 teaspoon lemon zest to the final blend. Storage tip: The sauce thickens as it chills, so add ice water gradually if it becomes too stiff after refrigeration.

This sauce keeps beautifully for 5 days refrigerated in an airtight container. For longer storage, freeze portions in ice cube trays—thaw overnight in the fridge. The texture transforms magically when chilled, becoming silky and pourable. Double the batch if you're serving a crowd—it disappears fast with charcuterie boards. Garnish with a drizzle of olive oil and extra sherry vinegar right before serving to restore its vibrant pale green hue.

Step-by-step instructions for ajo blanco sauce

Master this Andalusian classic with a velvety, chilled celery-almond sauce that balances creaminess with bright vinegar notes.

Place the 0.5 cup toasted almonds in a dry skillet over medium heat. Toast for 3-4 minutes until they develop a golden aroma and deepen in color. Watch closely—they'll darken quickly. Transfer immediately to a cutting board and roughly chop with a knife, leaving some texture for body.

Meanwhile, tear the 0.5 cup stale bread into small pieces and set aside. The bread should be completely dry—if it's fresh, spread it on a baking sheet and bake at 300°F for 10 minutes to remove all moisture. This ensures your sauce won't be gummy. Keep both components separate until ready to blend.

Heat the 1.5 cups extra-virgin olive oil in a small saucepan over low heat. Add the 2 peeled garlic cloves and cook for 2-3 minutes until they're golden and fragrant—don't let them brown. Remove from heat immediately and let steep for 10 minutes to infuse the oil with garlic flavor. Strain through a fine-mesh sieve into a clean bowl, pressing gently on the garlic to extract all the essence.

The infused oil forms the sauce's base, so its quality matters. Use a fruity, high-quality olive oil—this is where the sauce's depth of flavor comes from. If the oil smells bitter after straining, start over with fresh oil and garlic.

In a food processor, combine the 1 cup finely chopped raw celery stalks, toasted almonds, stale bread pieces, and 0.5 teaspoon sea salt. Pulse until the mixture resembles coarse sand, with no large bread chunks remaining. This texture ensures a smooth sauce without over-processing the ingredients.

With the processor running, slowly drizzle in the 0.25 cup sherry vinegar. The vinegar adds the signature tang that balances the richness. Process for 30 seconds to emulsify slightly, then stop and scrape down the sides. This step prevents the motor from overheating and ensures even blending.

With the processor running on low speed, very slowly pour in the infused olive oil through the feed tube. This gradual addition creates a stable emulsion—adding it too quickly will break the sauce. Process for 1-2 minutes until completely smooth and creamy, scraping down the sides as needed.

Transfer the sauce to a bowl and taste. It should be rich but not overly thick. If needed, thin with ice water 1 tablespoon at a time until it reaches a pourable consistency—it should coat the back of a spoon but still flow freely. The 0.5 cup ice water is your reserve for adjustments.

Cover the sauce and refrigerate for at least 2 hours (or up to 24 hours) to allow flavors to meld and the texture to set properly. The longer it chills, the more pronounced the almond and celery flavors become. Before serving, give it a quick stir to redistribute any settled ingredients.

This sauce pairs beautifully with cold grilled shrimp or seafood dishes. Serve it well-chilled in a chilled bowl to maintain its refreshing quality. The contrast between the cool sauce and warm protein creates a perfect balance in every bite.

Perfect pairings for these flavors

Tapas Board Essentials

Serve ajo blanco with classic Spanish cured meats like jamón ibérico or chorizo—the creamy sauce cuts through the saltiness beautifully. I love adding marinated anchovies and olives for contrast. For a vegetarian spread, include roasted red peppers, manchego cheese, and crusty baguette slices.

The cool sauce also elevates smoked salmon or boquerones (fresh anchovies) with a single drizzle. 🥗

Seafood Pairings

This sauce shines with cold seafood dishes. Try it with grilled prawns or chilled calamari rings—the almond creaminess balances the briny flavors. For a complete meal, serve with shrimp cocktail or seared scallops.

The vinegar notes in ajo blanco also complement grilled octopus perfectly. I often make a double batch to have on hand for summer seafood feasts. 🦐

Salad Enhancements

Use ajo blanco as a creamy dressing for cucumber and tomato salads. Toss with diced cucumbers, cherry tomatoes, and red onion slices for a refreshing Andalusian-inspired dish.

It also works beautifully with arugula salads—just drizzle lightly and add toasted pine nuts for crunch. For a heartier option, mix with roasted eggplant and feta cheese. 🥒

Bread Dippers

No charcuterie board is complete without ajo blanco for dipping. Use crusty sourdough, garlic bread, or even pita chips. For extra flair, toast baguette slices with garlic butter before dipping.

The sauce also pairs wonderfully with empanadas or tortilla española—the contrast of warm, spiced foods with cool ajo blanco is pure magic. 🥖

Modern Twists

Get creative with this versatile sauce! Use it as a marinade for grilled vegetables like zucchini or bell peppers. It also makes an excellent base for cold soups—simply add diced cucumber or avocado for extra freshness.

For a dessert twist, drizzle over fresh berries with a sprinkle of honey. The possibilities are endless once you master the base recipe. ✨

Wine & Drink Pairings

Pair ajo blanco with crisp Spanish whites like Albariño or Verdejo—their citrus notes complement the sauce's vinegar brightness. For red wine lovers, try a light Ribera del Duero with subtle tannins.

Non-alcoholic options? Sparkling San Pellegrino or ginger beer add effervescence that cleanses the palate. The key is balancing the sauce's richness with something refreshing. 🍷
