Roasted Garlic Aioli Dip
A silky, luxurious dip built on roasted garlic and egg yolks emulsified with olive oil. The deep sweetness of roasted garlic balances bright lemon juice and sharp Dijon mustard, making this aioli perfect for crudités, grilled vegetables, or as a spread for sandwiches. Unlike jarred mayonnaise-based dips, this homemade version has genuine garlic flavor and a velvety texture that feels restaurant-quality.

Steps
Before you start
- Remove eggs from the refrigerator 15 minutes before making the aioli so they're at room temperature (critical for emulsification)
- Preheat the oven to 400°F (200°C)
- Ensure all equipment is clean and dry—any water or oil residue will prevent proper emulsification
Prepare and roast garlicOven 400°F / 205°C
- Cut the tops off both garlic heads to expose the cloves.
- Place them cut-side up on a sheet pan.
- Drizzle with 2 tablespoons (30 ml) of olive oil, then season lightly with sea salt and black pepper.
- Roast in a 400°F (200°C) oven for 35 minutes, until the exposed cloves are golden and very soft—they should squish easily with a fork.

Ready when: Garlic cloves are deep golden and soft enough to squeeze from skin
Tip: Don't rush the roasting—the longer, slower cooking transforms raw garlic's harsh bite into mellow sweetness.
Cool roasted garlic
- Remove the pan from the oven and let the garlic cool for about 10 minutes until you can handle it comfortably.
- Once cool, squeeze the soft cloves out of their skins into a small bowl.
- You should have roughly 3–4 tablespoons (30–40 g) of roasted garlic puree.

Ready when: Garlic is cool enough to touch and squeeze from the skin
Tip: Squeeze gently—the pulp comes out easily when fully roasted. Discard the papery skins.
Combine egg yolks and flavorings
- Add the 2 room-temperature egg yolks to the roasted garlic in your bowl.
- Add the Dijon mustard and 1 tablespoon (15 ml) of the lemon juice.
- Whisk vigorously for about 30 seconds until everything is well combined and pale—this aerates the yolks and helps them accept the oil.

Ready when: Mixture looks pale and smooth, with no visible streaks
Tip: Whisk hard to incorporate air—this helps the emulsion form. Room-temperature eggs are essential or the emulsion may break.
Begin adding oil slowly
- Pour the ¾ cup (180 ml) of olive oil into a liquid measuring cup or small pitcher.
- While whisking constantly and vigorously, add the oil one teaspoon at a time at first, incorporating each addition fully before adding more.
- After you've added about 3 tablespoons (45 ml) and the mixture looks visibly thicker and paler, you can switch to a thin, steady drizzle while continuing to whisk.

Ready when: Aioli thickens noticeably as oil is incorporated; mixture looks creamy and glossy
Tip: Go slowly at first—if you add oil too quickly, the emulsion breaks and you'll end up with a separated mess. Patience here pays off.
Complete the emulsion
- Continue whisking in the remaining oil in a thin stream.
- The aioli will become thicker and glossier as more oil incorporates.
- If it gets too thick and hard to whisk, stop the oil and add a teaspoon of the ice-cold water, then resume whisking and adding oil.
- Repeat with water as needed until all the oil is incorporated and the aioli has a smooth, creamy, spreadable consistency.

Ready when: All oil is incorporated; aioli is thick, glossy, and holds its shape on a spoon
Tip: If the aioli does break (looks curdled or separated), start fresh with a new yolk in a clean bowl, then slowly whisk in the broken mixture to rescue it.
Finish and adjust seasoning
- Whisk in the remaining 1 tablespoon (15 ml) of lemon juice.
- Taste and adjust with a pinch more sea salt, black pepper, or lemon juice as you prefer.
- The aioli should taste rich but bright, with roasted garlic as the star flavor.

Ready when: Seasoning is balanced—garlic is prominent, lemon is bright, no single flavor dominates
Tip: Add lemon juice at the end so you can taste as you go; too much acid can affect the texture slightly.

Tips
- Room-temperature eggs are non-negotiable—cold eggs won't emulsify properly. Remove them from the fridge 15 minutes before starting.
- If your aioli breaks (looks curdled or separates), don't panic. Start with a fresh egg yolk in a clean bowl, then very slowly whisk in the broken aioli while whisking hard—this often rescues it.
- For extra-thick aioli, use slightly less oil; for a thinner dip consistency, whisk in a bit more cold water at the end. Thickness is entirely to your preference.
- Roasted garlic can be made up to 3 days ahead and stored in the fridge, making the aioli quick to assemble on serving day.
Storage & reheating
Store in an airtight container in the refrigerator for up to 4 days. The aioli may separate slightly as it sits; whisk in a teaspoon of cold water and stir well to restore its texture. Do not freeze, as the emulsion will break when thawed.
Substitutions
- large egg yolks, at room temperature → 1 whole large egg at room temperature. Use this if you're uncomfortable with raw yolks or have concerns about food safety. The result will be slightly less rich but still excellent.
- extra-virgin olive oil, for emulsifying → light olive oil or neutral oil (avocado, grapeseed). Neutral oils produce a lighter-tasting aioli. Extra-virgin olive oil gives deeper flavor but can taste grassy if overwhisked or warmed—use gentle, steady whisking.
- fresh lemon juice, divided → white wine vinegar (1½ tablespoons / 22 ml total) or champagne vinegar. Vinegar adds brightness with a slightly different tang. Use a touch less since vinegar is more acidic than lemon juice.
- Dijon mustard → whole-grain mustard (same amount). Whole-grain adds a subtle texture and rustic character; the flavor is slightly less sharp but still balances the richness.
