This is a garlic-forward, homemade aioli built on a Dijon mustard and olive oil emulsion — essentially a punchy, hand-whisked mayo that takes about 15 minutes and no special equipment. It’s worth making from scratch because the flavor is sharper and fresher than anything from a jar, and it pulls a burger or sandwich together in a way that bottled condiments just don’t.
Why this recipe works
Two things make or break this aioli. First, the Dijon mustard isn’t just flavor — it contains compounds that actively help the oil and egg yolks bond into a stable emulsion, which is why you whisk it in before the oil ever touches the bowl. Second, the oil addition speed matters more than most people expect: the first few tablespoons need to go in almost drop by drop while you whisk hard. That’s when the emulsion forms. Once it looks thick and creamy, you can pour in the rest in a thin, steady stream. Rush that first stage and the sauce breaks. Get it right and you end up with a glossy, spoonable aioli that holds its texture for days.
If something goes sideways
- The aioli broke and looks greasy or curdled: Whisk a fresh egg yolk in a clean bowl, then slowly whisk the broken mixture into it a little at a time. It almost always comes back together.
- The garlic tastes harsh or sharp: Raw garlic can be aggressive. After mashing it with salt, let the paste sit for five minutes before adding it to the yolks — the salt draws out moisture and mellows the bite slightly.
- It’s too thick to spread: Whisk in cold water, half a teaspoon at a time, until you reach the consistency you want. Don’t add more lemon juice to thin it — that can tip the flavor balance.
- It tastes flat even after seasoning: A small pinch of white pepper added with the salt rounds out the flavor without changing the color or adding visible flecks.
- The emulsion won’t thicken at all: Your egg yolks were probably too cold. Room-temperature yolks emulsify much more reliably — pull them out of the fridge at least 20 minutes before you start.
Smart swaps
- Extra virgin olive oil: A strongly flavored EVOO can make the aioli taste bitter, especially in larger batches. If that’s a concern, use half EVOO and half a neutral oil like avocado or light olive oil — you still get the flavor without the edge.
- Dijon mustard: Whole-grain Dijon works and gives the aioli a slightly coarser texture with visible mustard seeds, which looks good on a burger. Standard yellow mustard is too sweet and will throw off the balance.
- Lemon juice: White wine vinegar is a clean substitute if you’re out of lemons — use the same amount.
- Aquafaba (vegan swap): Replace both egg yolks with 3 tablespoons of aquafaba. The emulsion is slightly less rich but still stable and spreadable.
Storage and reheating
Store the aioli in a sealed container in the refrigerator for up to 4 days. Because it contains raw egg yolk, don’t leave it sitting out at room temperature for more than 2 hours. It will firm up in the fridge — just give it a quick stir before serving and it loosens right back up. This aioli doesn’t freeze well; the emulsion breaks on thawing and doesn’t recover cleanly, so make only what you’ll use within the week. There’s no reheating involved — serve it cold or at room temperature straight from the fridge.
French Dijon Mustard Aioli
Ingredients
- 2 cloves Garlic peeled and finely minced
- 2 tablespoons Dijon mustard preferably French
- 1 cup Extra virgin olive oil cold-pressed and fruity
- 2 large Egg yolks from free-range eggs, room temperature
- ½ teaspoon Sea salt finely ground
- 1 tablespoon Lemon juice freshly squeezed
Instructions
- In a mortar and pestle, mash the garlic cloves with a pinch of sea salt until a smooth paste is formed. Alternatively, use a garlic press for a quicker method.
- In a medium-sized mixing bowl, whisk together the Dijon mustard, mashed garlic, and egg yolks until the mixture becomes creamy and smooth.
- While whisking continuously, slowly drizzle in the olive oil, a few drops at a time at first, then gradually increase to a thin stream. The aim is to emulsify the mixture, creating a rich and creamy aioli.
- If the mixture becomes too thick, add a few drops of water to help maintain the emulsion.
- Once all the oil is incorporated and the aioli is smooth and glossy, whisk in the fresh lemon juice to balance the flavors.
- Taste and adjust seasoning with additional salt and a touch more lemon juice if needed.

Your questions, answered
Is it safe to eat aioli made with raw egg yolks?
For most healthy adults, the risk from raw egg yolks in a home-made aioli is low but not zero. If you’re cooking for pregnant people, young children, elderly guests, or anyone immunocompromised, use pasteurized eggs — they’re available at most grocery stores and work exactly the same way in this recipe.
Can I make this with a blender or food processor instead of whisking by hand?
Yes, and it’s faster and more foolproof. Add the yolks, garlic paste, and mustard to the blender, blend briefly to combine, then drizzle the oil in through the feed tube while the machine runs. The result is slightly airier than the hand-whisked version but just as stable.
What’s the best way to use this aioli on a burger?
Spread it on both the top and bottom bun — it acts as a moisture barrier that keeps the bun from going soggy, and you get aioli in every bite. Skip the egg in the mix — it makes the patty mushy, so keep the aioli as your richness source and let the patty stay lean and well-seasoned on its own.
Why does my aioli taste more bitter than tangy?
Bitterness almost always comes from the olive oil, not the mustard or garlic. Strong, peppery extra virgin olive oils can turn noticeably bitter when emulsified in large quantities. Switching to a milder EVOO or cutting it with a neutral oil like avocado oil fixes this immediately.
