You’re standing in the grocery aisle or staring at a fancy bistro menu. You want that creamy, garlic-infused goodness, but then you pause. How do you spell aioli anyway? Is it "aoli"? Does it have two Ls? Is there a random "y" in there somewhere? Honestly, it’s one of those words that looks like a literal vowel salad. Five letters, four of them are vowels. It’s a linguistic nightmare for most of us.
Basically, the correct spelling is aioli.
It comes from the Occitan and Catalan words for garlic (all) and oil (oli). If you can remember "all and oil," you’ve basically mastered the etymology and the spelling in one go. But knowing how to spell it is only half the battle. The real tragedy in the culinary world isn't just a typo on a menu; it's what we’ve done to the sauce itself. Most people think they're eating aioli when they're actually just eating "garlic mayo." There is a massive, spicy difference between the two, and if you're a food purist, the distinction matters.
The Vowel Trap: Why Your Brain Wants to Misspell Aioli
English speakers struggle with this word because it ignores our standard phonetic rules. We want to put an "a" and an "o" together, but that "i" in the middle acts as a bridge that feels unnatural to type. You’ll often see "ayoli" or "aoli" in search bars. It’s okay. Even professional chefs have been caught misspelling it on chalkboard specials.
The word is French by way of Provence. In French, it’s often written with a tréma over the "i"—aïoli—which tells you to pronounce the "a" and the "i" separately. Think "ah-ee-OH-lee." When we brought it into English, we ditched the dots but kept the confusing vowel string. If you’re trying to remember how do you spell aioli under pressure, just think of the word "ail" (the French word for garlic) and add "oli."
Actually, let's look at why this word is so weird. It’s a Mediterranean staple. It’s ancient. It’s a sauce that has survived centuries of linguistic shifts, yet we still treat it like a trendy new condiment.
Stop Calling Your Mayo Aioli
Here is the truth: 90% of the time you see "chipotle aioli" or "truffle aioli" on a burger menu, it’s a lie. It’s just mayonnaise with stuff stirred into it.

Traditional, hardcore Mediterranean aioli—the kind you find in Provence or Catalonia—does not contain eggs. It is a stubborn, difficult emulsion of nothing but garlic cloves, olive oil, and maybe a pinch of salt. That’s it. You crush the garlic in a mortar and pestle until it’s a paste, then you add the oil drop by drop, whisking like your life depends on it, until it thickens into a glorious, pungent cloud.
Mayo, on the other hand, is an emulsion of oil and egg yolk (and usually vinegar or lemon juice).
- Traditional Aioli: Garlic + Olive Oil + Salt.
- Modern "Cheat" Aioli: Mayonnaise + Garlic.
- The Hybrid: Egg yolk + Garlic + Olive Oil (often called Alioli in Spain).
Is it pretentious to care? Maybe. But if you’re paying $18 for a plate of fries, you should probably know if you’re getting a hand-emulsified garlic sauce or just some Hellman’s with a squeeze of garlic paste.
How Do You Spell Aioli Variations Around the Globe?
Depending on where you are in the world, the spelling shifts slightly. This adds to the confusion. In Spain, specifically in Catalonia and Valencia, it’s alioli. This actually makes more sense phonetically for the "garlic and oil" roots.
In some parts of Italy, you might hear people refer to agliata, which is a similar garlic-heavy sauce used for meats and fish. However, for the international standard that you’ll find in cookbooks and on the web, "aioli" is the undisputed king.
If you're writing a menu or an article, stick to the five-letter version.
Common Misspellings to Avoid
- Aoli (Missing the middle "i")
- Aioli (Double "l" - this is a very common mistake)
- Ayoli (Phonetic spelling that is technically incorrect)
- Alioli (Correct in Spain, but confusing in the US/UK)
The Science of the Emulsion
Why is it so hard to make? If you've ever tried to make the eggless version, you know it breaks easily. You end up with a greasy, garlicky soup instead of a thick spread.
Garlic contains surfactants—compounds that help oil and water-based juices stay together. But they aren't as strong as the lecithin found in egg yolks. This is why many modern recipes (and almost all restaurants) cheat by adding an egg yolk. It stabilizes the sauce. It makes it foolproof.
Harold McGee, the legend of food science and author of On Food and Cooking, points out that the traditional method requires an incredible amount of physical force. You are literally smashing the oil molecules into the garlic cells. It’s a workout. Most people aren't doing that for a Tuesday night dinner.

Regional Pride and Garlic Breath
In the south of France, Le Grand Aïoli isn't just a sauce; it's a whole event. We're talking a massive platter of salt cod, boiled vegetables, snails, and hard-boiled eggs, all served with a giant bowl of the namesake sauce. It is a communal feast.
If you show up there and ask "how do you spell aioli," they might give you a strange look, but if you suggest it's just garlic mayo, you might get kicked out of the village. The cultural weight of this sauce is massive. It represents the "Cuisine of the Sun." It’s meant to be powerful. It’s meant to make your breath smell like garlic for three days.
Honestly, the modern obsession with making everything "light" or "subtle" has ruined aioli. Real aioli should be aggressive. It should bite back.
Actionable Tips for Better Aioli (and Better Spelling)
If you want to move beyond just knowing the spelling and actually master the sauce, here is what you need to do. Forget the store-bought jars. They are mostly soybean oil and "natural flavors."
1. Use the Right Oil
Don't use extra virgin olive oil for the whole thing. It’s too bitter when emulsified at high speeds (like in a blender). Use a neutral oil like grapeseed or avocado for the bulk of the volume, then finish with a splash of high-quality olive oil for flavor.
2. The Garlic Trick
Remove the "germ" (the little green sprout) from the center of the garlic cloves. That’s where the bitter, acrid heat lives. Removing it makes the sauce smoother and more palatable.
3. Use a Mortar and Pestle
If you want the real deal, ditch the food processor. The texture is different. The food processor cuts; the mortar and pestle bruises and crushes, releasing essential oils that a blade just misses.
4. Acid Balance
Even though the traditionalists stick to oil and garlic, a tiny squeeze of lemon juice at the end brightens the whole thing. It cuts through the fat.
The Wrap Up on Aioli
Knowing how do you spell aioli is a small victory for your vocabulary, but understanding the difference between a cheap imitation and a Mediterranean masterpiece is a victory for your kitchen. Next time you're writing it down, just remember the vowels: A-I-O-L-I.

If you're feeling adventurous, try making it from scratch. Start with two cloves of garlic and a pinch of salt. Grind them into a paste. Add oil slowly. Very slowly. If it works, you’ll never look at a jar of mayo the same way again. If it breaks, don’t panic—just whisk in a teaspoon of warm water or an egg yolk to bring it back to life.
Next Steps for the Culinary Curious:
- Check your pantry: If you have "garlic aioli" in the fridge, check the ingredients. If the first ingredient is soybean oil or eggs, it’s technically a flavored mayonnaise.
- Practice the spelling: Write it five times. A-I-O-L-I. It’ll stick eventually.
- Try the Spanish version: Look up a recipe for "Alioli Negre," which uses squid ink for a dramatic, jet-black garlic sauce.
The world of Mediterranean sauces is deep and flavorful. Don't let a few confusing vowels keep you from exploring it. Just keep the garlic fresh and the oil flowing.
