Full Ingredients

Classic Garlic-Lemon Aioli (From Scratch)

• 3–4 medium garlic cloves (about 12 g), peeled
• 1/2 teaspoon kosher salt (plus more to taste)
• 1 large egg yolk (pasteurized if desired), at room temperature
• 1 1/2 tablespoons fresh lemon juice (plus more to taste)
• 3/4 cup (180 ml) extra-virgin olive oil
• 1–3 teaspoons ice-cold water, as needed to adjust thickness
• Freshly ground black pepper, to taste

Shortcut Garlic-Lemon Aioli (Mayo-Based)

• 1 cup (230 g) good-quality mayonnaise
• 2 garlic cloves (about 8 g), very finely grated or minced
• 1 tablespoon fresh lemon juice (plus more to taste)
• 1 tablespoon extra-virgin olive oil
• Pinch of kosher salt and black pepper

Step-by-Step Instructions

Step 1: Prep and set up

Bring the egg yolk to room temperature for 10–15 minutes; a warmer yolk emulsifies more easily. Secure a medium mixing bowl on a damp towel to keep it steady. Assemble a whisk, measuring spoons, and your oil in a container with a spout for controlled pouring.

Step 2: Make a smooth garlic paste

Combine the garlic and kosher salt in a mortar and pestle and pound until completely smooth and creamy. No mortar? Mince the garlic, then mash repeatedly with the side of a chef’s knife and the salt until a fine paste forms. Scrape the paste into your mixing bowl.

Step 3: Start the emulsion

Add the egg yolk and lemon juice to the garlic paste. Whisk vigorously until the mixture is homogeneous, slightly thickened, and a bit frothy—about 30–45 seconds. This acidic base helps the emulsion form and stay stable.

Step 4: Drizzle in the oil slowly

Begin adding the olive oil drop by drop while whisking constantly. After the mixture visibly thickens, continue with a very thin stream. The sauce should become glossy and thick like soft mayonnaise. If the stream gets too fast and it looks oily or separated, pause and whisk vigorously to catch up before adding more oil.

Step 5: Adjust texture and season

When all the oil is incorporated, whisk in 1–3 teaspoons ice-cold water to reach your desired consistency (thick for spreading, slightly looser for dipping). Taste and adjust with more lemon juice, salt, and black pepper as needed. Let the aioli rest 10 minutes so the garlic mellows and flavors bloom.

Step 6: Mayo shortcut option

Whisk mayonnaise with the grated garlic, lemon juice, and olive oil until smooth and slightly glossy. Season with salt and pepper. Rest 10 minutes before serving.

Pro Tips

• Emulsion insurance: Add the oil painfully slowly at first. Once it thickens, you can speed up to a thin stream.
• Balance the flavor: If it tastes sharp, a pinch more salt and an extra minute of resting will round out the garlic.
• Texture control: Whisk in ice water a teaspoon at a time to loosen without dulling flavor.
• Gentler flavor: Use a milder olive oil or blend 1/2 extra-virgin with 1/2 neutral oil for a softer profile.
• Food safety: Use pasteurized eggs for the classic version, or default to the mayo shortcut if serving young children, pregnant individuals, or immunocompromised guests.

Variations

• Roasted Garlic Aioli: Substitute 6 roasted garlic cloves for raw for a sweeter, mellow flavor.
• Herb Aioli: Stir in 2 tablespoons finely chopped parsley, chives, or dill at the end.
• Smoky Lemon Aioli: Add 1/2 teaspoon smoked paprika and a pinch of cayenne.

Storage & Make-Ahead

Transfer aioli to a clean, airtight jar and refrigerate up to 3 days for the classic version or 5 days for the mayo shortcut. Keep cold and use clean utensils to avoid contamination. The flavor improves after 1–2 hours in the fridge. If it thickens too much, whisk in a teaspoon of cold water or a few drops of lemon juice just before serving.
