Oaxaca Cheese (Quesillo): How It’s Made and Why Everyone Loves It

If you’ve eaten a tlayuda, a quesadilla, or almost anything off a comal in Oaxaca, you’ve already met quesillo. That stretchy, creamy, slightly salty cheese that pulls apart in ribbons and melts into everything it touches.

I’ve lived in Oaxaca City for over 10 years, and I still think it’s one of the best things you can eat here. Simple, fresh, and completely its own thing.

Here’s everything you need to know about it.

What Is Oaxaca Cheese (Quesillo)?

Quesillo is a semi-soft white cheese made from cow’s milk. The curds are heated, stretched by hand into long elastic ribbons, then rolled into a ball or knot.

Technically it belongs to the same stretched-curd family as mozzarella — but stop right there, because that comparison only goes so far. Quesillo is firmer, saltier, and stretches more dramatically. It melts into something smooth and creamy rather than oily. And it has a flavour that’s subtle but distinct — mild and buttery, with just enough salt to keep things interesting.

Mozzarella has its place. But quesillo owns the quesadilla.

Quesillo or Oaxaca Cheese? The Local Debate

Here’s something worth knowing before you ask for it at a market.

Inside Oaxaca, it’s quesillo. That’s the original name, and locals say it with a quiet pride. “Oaxaca cheese” is what it became known as once it spread across Mexico and abroad — easier to say, easier to sell, but not what anyone here calls it.

If you walk up to a market stall and ask for quesillo, you’ll get a nod of approval. Ask for “Oaxaca cheese” and you might get a raised eyebrow and a smile.

It’s a small thing, but it matters to people here. Use the right name.

Where Did Quesillo Come From?

Quesillo has its roots in Etla, a small town about 30 minutes north of Oaxaca City, and it goes back well over a hundred years.

The most repeated origin story involves a young girl who accidentally overheated a batch of cheese curds. Instead of throwing them out, she stretched them by hand — and discovered that the result was something elastic, smooth, and unlike anything else being made at the time.

True or not, the story fits. Quesillo feels like an accidental discovery that turned out to be genius.

Today, families in the valleys around Oaxaca still make it using methods that haven’t changed much. You can watch the whole process at local cheese-making experiences just outside the city — more on that below.

What Does It Taste Like?

Mild, creamy, and lightly salted — but the flavour is almost secondary to the texture.

The real magic of quesillo is the way it behaves. It melts evenly and stays silky rather than turning greasy. It stretches without snapping. It holds up in hot dishes without breaking down. That’s why it works in so many different contexts — melted, fresh, grilled — and why nothing else quite replaces it.

If you’ve only had supermarket mozzarella, your first bite of fresh market quesillo is going to feel like an upgrade.

How do people eat quesillo in Oaxaca?

Three main ways, and all of them are good.

Melted — This is the classic. Quesillo in quesadillas, tlayudas, empanadas, and memelas. It melts fast, stays smooth, and ties the whole dish together. Most Oaxacan street food that involves cheese involves quesillo.

Fresh, pulled by hand — Buy a ball at the market, pull it apart into strands, and eat it as a snack. No fuss, no cooking. This is how a lot of locals eat it at home, and it’s the best way to taste it properly on its own.

Grilled — Lightly fried until the outside crisps up and the inside goes gooey. A completely different experience from the fresh version, and just as good.

You’ll find it everywhere — from street stalls to sit-down restaurants — but fresh from the market is hard to beat.

Where To Buy The Real Thing In Oaxaca City?

Skip the supermarket, at least for your first time.

The best quesillo in Oaxaca City comes from the markets, where it’s made fresh daily and sold in large ribbon balls. The three worth knowing:

Mercado Benito Juárez — Central, easy to get to, and full of good food stalls alongside the cheese vendors. A solid first stop.

Mercado 20 de Noviembre — The one food lovers tend to gravitate toward. The quality is consistently high and the atmosphere is hard to beat.

Sánchez Pascuas market — Less touristy than the other two, and a good option if you want to browse somewhere that feels more like a neighbourhood market.

Chedraui and Walmart stock it too, and it’s perfectly fine in a pinch — but the market version is fresher, tastier, and usually cheaper.

How Much Does It Cost?

In Oaxaca in 2026, you’re looking at around 50 pesos (about $2.50 USD) for 250 grams at the market.

It’s one of the most affordable things you can buy here, which makes it all the more baffling that the supermarket version costs more and tastes worse.

Why Quesillo Is Worth Your Attention

Oaxaca has a reputation as one of Mexico’s great food destinations, and quesillo is part of the reason why. It’s not a complicated ingredient — it’s just fresh cheese, made with care, using a process that’s barely changed in over a century.

But that simplicity is the point. Quesillo does exactly what it’s supposed to do, every time. It melts perfectly, it tastes clean, and it makes everything it touches better.

Try it fresh from the market, melted into a tlayuda, and pulled apart by hand at a roadside stall. Three different experiences, one ingredient.

That’s Oaxacan food in a nutshell.
