Ingredients for ajo blanco soup
Transform humble pantry staples into Andalusian elegance with this chilled garlic masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Whole Garlic Cloves 🧄 | 12 cloves | Blanched for mellow sweetness |
| Raw Almonds 🥜 | 1 ½ cups | Skin-on for authentic texture |
| Stale Bread 🍞 | ½ loaf | Day-old crusty bread preferred |
| Extra-Virgin Olive Oil 🫒 | 1 ½ cups | High-quality, fruity variety |
| Fresh Celery Stalks 🧅 | 4 whole | Thick stalks for crispy crowns |
| Lemon Juice 🍋 | ½ cup | Freshly squeezed, strained |
| Cold Water 💧 | 4 cups | Filtered preferred for clarity |
| Smoked Paprika 🌶️ | 1 tsp | For depth of flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked preferred |
| Crusty Bread 🍞 | 6 slices | For serving and dipping |
| Smoked Salmon 🐟 | 6 oz | Optional garnish, thinly sliced |
| Black Olives 🫒 | ¼ cup | Pitted, for garnish |
The garlic is non-negotiable—Spanish garlic if you can find it, otherwise robust supermarket varieties. Whole Foods or Trader Joe's often carry the best quality. Blanching whole cloves mellows their intensity while preserving sweetness—don't skip this step. For almonds, skin-on is traditional, but blanched works too. The bread should be stale but not moldy—day-old baguettes from a good bakery are ideal. Look for high-quality extra-virgin olive oil with fruity notes; California Olive Ranch is a reliable choice.
No blanching water? Cold water from the fridge works in a pinch. Substituting almonds? Cashews at equal weight soften similarly, though texture differs slightly. For the celery crowns, thick stalks crisp best—avoid the thin, stringy ones. The smoked paprika adds depth without overpowering; Penzeys brand is excellent. If you're avoiding seafood, the soup still shines with just the crispy celery and a sprinkle of smoked paprika. For extra richness, add a splash of almond milk to the blending stage.
This soup stays fresh for 3 days in the fridge, though it's best within 24 hours of making. The crispy celery crowns should be prepared fresh before serving—they lose crunch quickly. For make-ahead convenience, blanch and store the garlic cloves separately until ready to blend. Garnishes like smoked salmon and olives can be added just before serving to maintain texture. The soup thickens slightly when chilled, so add a splash of cold water if it becomes too dense.

Step-by-step instructions for ajo blanco soup
Master this Andalusian classic with crispy celery crowns and velvety almond cream.
Blanch the Garlic and Prepare the Celery Crowns
Peel the 12 cloves whole garlic cloves and bring 4 cups cold water to a gentle simmer in a saucepan. Add the garlic cloves and simmer for exactly 5 minutes until they turn translucent and mellow. Drain immediately and set aside—this blanching prevents bitterness and creates sweet, aromatic garlic for the base.
While the garlic cooks, trim the 4 whole fresh celery stalks by cutting off the leafy tops and reserving them for another use. Using a sharp knife, slice each stalk lengthwise into ¼-inch thick planks. Then, cut each plank into 2-inch long pieces. Arrange these celery pieces on a baking sheet lined with parchment paper, drizzle with 1 tablespoon of the extra-virgin olive oil, and sprinkle with ½ teaspoon salt. Bake at 400°F for 15-18 minutes until golden brown and crispy—this is the signature crown that tops the soup.
Toast the Almonds and Prepare the Bread
Spread the 1.5 cups raw almonds on a dry baking sheet and toast in a preheated 350°F oven for 8-10 minutes, stirring once halfway, until fragrant and lightly golden. Remove from the oven and let cool slightly—this toasting enhances their nutty flavor and prevents bitterness in the soup.
Tear the 0.5 loaf stale bread into small pieces, discarding any hard crusts. This bread will absorb the garlic-infused water to create the soup's velvety texture. In a food processor, pulse the toasted almonds until they resemble coarse sand—this texture is crucial for achieving the signature creamy consistency without using dairy.
Create the Garlic-Infused Almond Cream Base
In a blender, combine the blanched garlic cloves, almond sand, 0.5 cup lemon juice, and 1.5 teaspoons salt. Blend on high for 1 minute until completely smooth, scraping down the sides as needed. With the blender running, slowly pour in 1 cup of the cold water used for blanching the garlic—this creates an emulsified base that will form the soup's creamy foundation.
Transfer the almond-cream mixture to a saucepan and place over medium heat. Stir in 1 teaspoon smoked paprika and 0.5 teaspoon ground black pepper. Simmer gently for 5-7 minutes, stirring occasionally, until the mixture thickens slightly and coats the back of a spoon. This step develops the soup's depth of flavor—don't rush it, as proper simmering ensures the almonds release their full nuttiness.
Assemble and Finish the Soup
Remove the saucepan from heat and stir in the remaining 3 cups cold water. The soup should now have a light, creamy consistency. Taste and adjust seasoning with additional salt if needed—this is your flavor baseline before adding the crispy elements.
To serve, ladle the ajo blanco into bowls, placing 3-4 crispy celery crowns on top of each portion. The contrast between the cold, creamy soup and the warm, crispy celery is what makes this dish truly special. Garnish with thin slices of smoked salmon and black olives if using, and serve immediately with the 6 slices crusty bread on the side for dipping.
Pro Tips For Making Ajo Blanco Soup
- Blister the Garlic: Don’t just mince it—peel whole cloves, smash them flat with the side of your knife, then fry in olive oil until edges blacken. I learned this the hard way: raw garlic tastes sharp; blistered garlic melts into velvety sweetness that carries the whole soup.
- Toast Almonds Until Golden: Dry-toast the raw almonds in a separate pan over medium heat until they smell nutty and turn pale gold—about 5-6 minutes. Skipping this step leaves them bitter and underwhelming; toasted almonds add texture and depth that stale bread alone can’t match.
- Soak Bread in Cold Broth: Tear the bread into chunks and soak them in cold broth (or water) for 10 minutes before adding to the pot. This prevents a gummy, gluey mess—my first attempt had bread clumps that sank like rocks. Cold soaking ensures even absorption.
- Simmer Low and Slow: After blending the soup, reduce heat to a bare simmer and let it cook uncovered for 20 minutes. Rushing it keeps the almonds raw-tasting and the celery harsh. Low heat lets flavors marry, and you’ll notice the celery soften into silkiness instead of mush.
Make-ahead tips for this ajo blanco soup
Prep Ahead Components
I always start by blanching the garlic cloves and toasting the almonds a day in advance. Store the blanched garlic in an airtight container in the fridge for up to 2 days—this preserves their sweetness and prevents oxidation.
The toasted almonds keep well in a sealed jar at room temperature for 3 days, ready to be pulsed into almond sand when needed. This prep saves 20 minutes of active time when you're ready to assemble the soup. 💡
Chilling Strategy
The key to perfect ajo blanco lies in proper chilling. After blending the almond-cream base, transfer it to a large bowl or pitcher and refrigerate for at least 4 hours, ideally overnight. This allows the flavors to meld completely and creates that signature velvety texture.
I like to use a glass bowl because it shows when the soup has fully chilled—it should have a slight sheen on top. For parties, I make the base 2 days ahead and store it in airtight containers with room for expansion.
Crispy Celery Timing
Save the celery crowns for last—they lose their crispness quickly. I recommend baking them 30 minutes before serving so they're piping hot when added to the chilled soup. If you're making this for a large group, bake two batches in 10-minute intervals to keep them fresh.
Store any extras in a paper towel-lined container at room temperature for up to 1 hour, but they're best served immediately. 🌟
Garnish Assembly
Keep smoked salmon, olives, and other garnishes separate until serving. Thinly slice the salmon with a sharp knife just before plating—this prevents it from drying out. Store olives in their original brine jar in the fridge for up to 1 week.
I assemble garnishes on a small platter at the table so guests can customize their bowls. This approach keeps everything fresh and adds a restaurant-quality presentation. ✨
Serving Temperature
Serve ajo blanco well-chilled at 40-45°F for the best texture. If the soup thickens too much after refrigeration, thin it with 1-2 tablespoons cold water at a time until it reaches your desired consistency. I like to serve it in pre-chilled bowls to maintain the cold temperature longer.
For extra elegance, place bowls on a large wooden board with crusty bread and olives arranged around them. This presentation makes it feel like a special occasion dish. 🍽️

Frequently asked questions
Why is ajo blanco traditionally served cold?
The chilled temperature highlights the soup's delicate almond-cream texture and mellow garlic flavor. Serving it cold also makes it perfect for hot Spanish summers while creating that signature refreshing contrast with warm garnishes like crispy celery crowns. The chilling process also allows flavors to meld beautifully over time.
Can I make ajo blanco without almonds?
Yes, but the texture will differ significantly. You can substitute 1 cup cashews for the almonds, though they'll create a slightly softer cream. For a dairy-free alternative, try blending ½ cup silken tofu with the garlic and lemon juice, though the flavor won't be identical. The traditional almond base is what gives ajo blanco its signature velvety texture.
How do I prevent ajo blanco from getting too thick?
Start with the full 4 cups cold water and thin as needed. If the soup thickens after chilling, add 1-2 tablespoons cold water at a time while stirring gently. Never use hot water as it will break the emulsion. The key is to maintain a light, creamy consistency that coats the back of a spoon without being heavy.
What's the best way to store leftovers?
Transfer the soup to airtight containers and refrigerate for up to 3 days. The crispy celery crowns should be prepared fresh before serving. For longer storage, freeze the base (without celery) for up to 1 month. When reheating, gently warm with a splash of water to restore creaminess, though it won't be as perfect as freshly made.
Can vegetarians enjoy ajo blanco?
This soup is naturally vegetarian when prepared without seafood garnishes. For extra richness, add avocado slices or poached eggs as toppings. The traditional Spanish version often includes seafood, but the base itself is completely plant-based and delicious as-is with fresh herbs like parsley or chives.
