You're standing at a taco stand in Mexico City or maybe a sandwich shop in Madrid. You want that creamy, tangy spread. You know what it is. You can see the jar. But suddenly, your brain freezes. You're wondering how to say mayo in Spanish without sounding like a textbook from 1995.
It's easy. It's mayonesa.
But honestly? If you just stop there, you’re missing the flavor of the language. Just like in English where we clip "mayonnaise" down to "mayo," Spanish speakers have their own ways of handling this condiment depending on where they are standing. If you're in a hurry, or just trying to sound like a local, there is a whole world of regional slang and culinary nuance to navigate.
The Standard Answer: Mayonesa
If you want to be 100% correct in any Spanish-speaking country, use mayonesa. It’s the universal term. It’s what is printed on the Hellmann's jars from Bogotá to Buenos Aires.
The pronunciation is pretty straightforward: mah-yoh-NEH-sah.
In most of Spain and Latin America, this is your go-to. It's safe. It's polite. It works. But let's be real—nobody says "mayonnaise" when they're ordering a burger at a drive-thru in Texas, and they don't always say the full word in Spanish either. In many places, especially in the Caribbean or parts of Mexico, you’ll hear people shorten it to mayo. It sounds exactly like the English version but with a slightly shorter "o" sound at the end.
Does "Mayo" Mean the Month?
Here is a funny thing about learning how to say mayo in Spanish. The word mayo already has a job. It's the month of May.
- "Cinco de Mayo" (Fifth of May)
- "Pásame la mayo" (Pass me the mayo)
Context is everything. Nobody is going to think you’re asking for a calendar month to be spread on your ham sandwich. However, some linguistic purists might give you a look if you use the shortened version in a fancy restaurant. If you're at a high-end bistro in Polanco, stick to mayonesa. If you're at a backyard BBQ in Miami, mayo is perfectly fine.

Regional Twists and The Salsa Secret
Language isn't a monolith. While mayonesa is the king, different regions have specific ways of referring to mayo-based sauces that you absolutely need to know if you don't want to be disappointed with your meal.
In Spain, specifically in the Balearic Islands, they claim to have invented the stuff. They call it mahonesa. Legend has it that the sauce originated in the city of Mahón on the island of Menorca. When French forces under the Duke de Richelieu captured the city in 1756, they supposedly took the recipe back to France, where it became mayonnaise. If you find yourself in Menorca, calling it mahonesa isn't just a linguistic choice; it's a point of local pride.
The "Salsa" Confusion
In many parts of Latin America, people don't just ask for mayo. They ask for salsa.
This can be incredibly confusing for Americans who associate "salsa" exclusively with chunky tomato and chili mixes. In Spanish, salsa just means "sauce." If you are in a cafeteria in Chile or Peru, and you see a white squeeze bottle, someone might just call it salsa blanca (white sauce) or salsa de mayonesa.
In Chile, they are obsessed with mayo. Like, really obsessed. It’s a national pastime. If you order a completo (the Chilean version of a hot dog), it will come topped with a mountain of homemade mayo. They don't just call it "mayo" there; they often specify if it's mayo casera (homemade). Trust me, there is a massive social divide between people who eat the store-bought stuff and those who make it fresh with lemon and oil.
It’s Not All Mayonesa: Related Condiments
Sometimes when you think you want to know how to say mayo in Spanish, what you're actually looking for is one of its cousins.
- Alioli: This is the big one in Spain. It's garlic and oil emulsified into a thick, mayo-like paste. While traditional alioli doesn't use egg, most modern versions are basically garlic mayonnaise. If you're in Barcelona, ask for alioli with your potatoes (patatas bravas).
- Aderezo: In Mexico and parts of Central America, "mayo" is often the base for an aderezo (dressing). If you want that creamy chipotle sauce, you aren't asking for mayo; you're asking for aderezo de chipotle.
- Crema: Don't mix these up. Crema is closer to sour cream or crème fraîche. It's thinner and tangier. If you put mayonesa on your enchiladas because you got the words mixed up, you’re going to have a very heavy, greasy dinner.
How to Use it Like a Native
Stop thinking in translations. Start thinking in phrases.

If you want to sound natural, you need the right verbs. In English, we "put" mayo on things. In Spanish, you "add" it or "apply" it.
- ¿Le pones mayonesa? (Do you put mayo on it?)
- Con mucha mayo, por favor. (With a lot of mayo, please.)
- Sin mayonesa. (Without mayo.)
If you’re at a grocery store, you’ll see labels like Mayonesa con limón (mayo with lime/lemon). This is incredibly popular in Mexico. It gives it a zing that the standard American blue-label jars lack. Honestly, once you try the lime version, the standard stuff tastes a bit flat.
The Great Mayonnaise Debate: Realities of the Kitchen
Let's talk about the texture. In Spanish culinary circles, the term emulsión is often used by chefs. If you’re watching a Spanish cooking show like MasterChef España, they might refer to the process of making mayo as montar la mayonesa (whipping or "mounting" the mayo).
There is also the "broken" mayo problem. If your oil and egg separate, you have a mayonesa cortada.
"Se me cortó la mayonesa." (My mayo broke/separated.)
This is a tragedy in a Spanish household. To fix it, you don't throw it away. You start with a new egg yolk and slowly drip the "broken" mixture into it. It’s a kitchen skill every "abuela" has mastered.
Beyond the Jar: Slang and Idioms
Language is weird. We use food words for things that have nothing to do with food. While mayonesa isn't as common in slang as, say, pan (bread) or leche (milk), it does pop up.

In some Caribbean contexts, calling someone or something "mayonesa" can imply they are "white" or "bland," but this is pretty niche and depends heavily on the specific island. For the most part, mayo stays in the kitchen.
However, there is the famous song "Mayonesa" by the Uruguayan group Chocolate. It was a massive hit in the early 2000s. The chorus goes: "Mayonesa, ella me bate como a la mayonesa" (Mayo, she beats/stirs me like mayo). It’s a metaphor for a girl making a guy's head spin. If you really want to impress your Spanish-speaking friends, put that on the jukebox. They’ll know you’ve done your homework.
Health and Substitutes
If you're looking for how to say mayo in Spanish because you're reading a label for health reasons, keep an eye out for baja en grasa (low fat) or vegana (vegan).
The vegan movement is exploding in cities like Madrid, Mexico City, and Santiago. You'll see veganesa on menus now. It's a portmanteau of vegana and mayonesa. It’s a quick way to know you’re getting a plant-based spread usually made from soy milk or aquafaba.
Actionable Steps for Your Next Trip
Don't just memorize the word. Use it correctly in the wild.
- Check the Label: Next time you're in the international aisle, look for a jar of McCormick Mayonesa (the one with the yellow lid). Look at the ingredients. Notice it says jugo de limones. That's the secret.
- Order with Confidence: Practice the phrase: "¿Me podrías dar un poco de mayonesa aparte?" (Could you give me a little mayo on the side?). It’s polite and uses the "apart" trick to keep your fries from getting soggy.
- Try the Regional Stuff: If you're in Spain, forget the jar. Ask for alioli. If you're in Chile, ask for mayo casera.
- Watch the "Y": Remember, the "y" in mayonesa functions like a soft "y" or even a "j" sound depending on the country (like in Argentina, where it might sound more like mah-zho-NEH-sah).
Knowing how to say mayo in Spanish is a small step, but it’s the difference between eating a dry sandwich and enjoying a meal exactly how you want it. Whether you call it mayonesa, mayo, or mahonesa, you're now equipped to handle any deli counter from Tijuana to Tierra del Fuego.
Go get that sandwich. You've earned it.
