This homemade garlic aioli whisks a single egg yolk, fresh garlic, lemon juice, and olive oil into a thick glossy sauce in about fifteen minutes by hand, with a sharp garlic bite in every spoonful.
The trick is adding the oil drop by drop at first so it blends into the yolk instead of separating, and once the sauce thickens you can pour a little faster. Serve it with fries, vegetables, or grilled meat.

Why This Homemade Garlic Aioli Recipe Works
Real garlic mashed into a paste with salt melts into the sauce, so you taste garlic in every bite without any harsh raw chunks hiding in the mix.
A single egg yolk holds a surprising amount of oil, and whisking slowly builds a stable emulsion that stays thick in the refrigerator for days.
Lemon juice brightens the richness of the oil, and a spoonful of Dijon mustard helps the sauce stay smooth if your arm gets tired halfway through.
Ingredients for Homemade Garlic Aioli
- For the sauce: two cloves garlic, one pasteurized egg yolk, one cup mild olive oil, one tablespoon lemon juice, and one quarter teaspoon salt.
- Optional: one teaspoon Dijon mustard for extra flavor and a steadier emulsion, plus a little warm water to thin the finished sauce.
Garlic: Fresh cloves give the sauce its sharp bite, and mashing them with salt breaks them into a smooth paste that disappears into the oil.
Egg yolk: The yolk is the emulsifier that holds the oil in tiny droplets, and pasteurized yolks lower the risk of raw egg illness.
Olive oil: Mild olive oil keeps the flavor smooth, while strong extra virgin oil can turn bitter once it is whisked into a sauce.
Lemon juice: Acid adds brightness and thins the sauce slightly, so squeeze it in at the end and taste before adding more.
Salt and Dijon: Salt seasons the garlic and helps grind it, and Dijon mustard is a small backup that stabilizes the emulsion.
How to Make Homemade Garlic Aioli
1. Make the garlic paste. Smash the cloves, sprinkle them with the salt, and mash with the flat of a knife until you have a smooth paste with no visible pieces.
2. Add the yolk. Scrape the paste into a bowl set on a damp towel, add the egg yolk and Dijon if using, and whisk until pale and well combined.
3. Start the oil. Add the oil a few drops at a time while whisking hard, and keep going until the mixture looks thick and glossy like soft mayonnaise.
4. Pour more steadily. Once the sauce holds together, drizzle the remaining oil in a thin steady stream, whisking constantly until all of it is blended in.
5. Season with lemon. Whisk in the lemon juice, taste, and add a pinch more salt if needed, then thin with a teaspoon of warm water if it feels too stiff.
6. Store the sauce. Spoon the aioli into a clean jar, cover tightly, and refrigerate right away since the sauce contains raw egg yolk.
How to Serve Homemade Garlic Aioli
Dip crispy homemade fries straight into the bowl, spread it on juicy cheeseburgers, spoon it beside air fryer asparagus, or stir a spoonful into creamy buttermilk coleslaw for extra tang.
How to Store and Reheat Homemade Garlic Aioli
Keep the aioli in a covered jar in the refrigerator for up to three days, and discard it if it smells off or turns watery. Do not leave it out for more than two hours, and skip freezing because the emulsion breaks when thawed. Stir gently before serving, since it will thicken in the cold.
Tips and Variations for Homemade Garlic Aioli
Use pasteurized yolks. Pasteurized eggs are safer for children, older adults, pregnant guests, and anyone with a weak immune system.
Flag the allergens. The sauce contains egg, and mustard is an allergen for some guests, so check labels on the Dijon.
Skip raw tasting. Do not taste the raw yolk mixture before the oil goes in, and keep every tool and bowl clean.
Steady the bowl. Set the bowl on a damp towel so it stays in place while you whisk with both hands.
Fix a split sauce. Whisk a fresh yolk in a clean bowl, then add the split sauce a teaspoon at a time until it comes back together.
Adjust the thickness. Add warm water by the half teaspoon if the aioli is too thick for drizzling over vegetables or fish.
Mellow the garlic. For a gentler bite, soak the garlic paste in the lemon juice for five minutes before adding the yolk.
Check trusted guidance. Read the Montana State University Extension egg fact sheet for safe egg handling.
Frequently Asked Questions About Homemade Garlic Aioli
How long does homemade garlic aioli last?
Keep it covered in the refrigerator for up to three days. Raw egg yolk makes the sauce perishable, so do not store it longer or leave it out.
Why did my homemade garlic aioli split?
The oil went in too fast at the start. Begin with drops, whisk firmly, and rescue a split sauce by whisking it into a fresh yolk.
Can I make homemade garlic aioli in a blender?
Yes. A small food processor or immersion blender works if you blend the yolk, garlic, and lemon first, then stream in the oil slowly until thick.
Is aioli the same as mayonnaise?
They are close relatives. Aioli leans on garlic and olive oil, while mayonnaise uses a neutral oil and usually less garlic.
What can I use instead of raw egg?
Use a pasteurized yolk, or whisk garlic and lemon into prepared mayonnaise for a quick shortcut without raw egg.
