A guide to Oaxaca cheese (quesillo) — Mexico's stretched, stringy melting cheese. How it's made, why it's wound into balls, and how to use it.
Oaxaca cheese, known in Mexico as quesillo, is the country's great melting cheese — soft, mild, and stringy, wound into a ball like a skein of yarn. If queso fresco and cotija are for crumbling, Oaxaca is for melting, and it's the cheese that makes quesadillas gooey and string-pulling.
What Oaxaca Cheese Is
Oaxaca cheese is a cow's-milk pasta filata (stretched-curd) cheese that originated in the state of Oaxaca in southern Mexico. It's made by the same stretching-and-kneading technique as mozzarella and string cheese — in fact, it's often described as Mexico's version of mozzarella. After the curd is stretched into long ribbons, it's wound into a ball, which is its signature form.
Why It's Wound Into a Ball
The distinctive ball shape comes from how the cheese is made. The warm, stretched curd is pulled into long, thin ropes, then wound around itself into a tight ball, much like winding string. To use it, you simply unwind the ball and pull the cheese into strands. This stringy, peelable quality is central to its identity and its appeal.
Flavor and Texture
Oaxaca cheese is mild, milky, buttery, and slightly salty, with a soft, elastic, stringy texture. Fresh, it pulls apart into smooth, springy strands and is pleasant to snack on. Its mild flavor and excellent melt make it less about bold taste and more about texture and gooeyness, the qualities that make it indispensable for melted dishes.
A Champion Melter
Oaxaca cheese melts smoothly and stretchily, making it the go-to cheese for melted Mexican dishes. It's the classic choice for quesadillas, where it melts into long, satisfying strings, and for queso fundido (melted cheese dip), chiles rellenos, and tlayudas. It's also excellent on pizza or anywhere you'd use mozzarella for a stretchy melt.
How to Use Oaxaca Cheese
To use it, unwind the ball and tear the cheese into strands or chop it. Pile it into quesadillas and tacos, melt it into queso fundido with chorizo, stuff it into peppers, or scatter it over baked dishes. Because it melts so well and tastes mild, it's a versatile substitute for mozzarella in many recipes, with a slightly saltier, more savory edge.
Pairings
Oaxaca cheese pairs naturally with Mexican flavors — chilies, chorizo, salsa, beans, and tortillas — and with light, refreshing drinks. Its mild creaminess balances spice and acidity beautifully.
Buying and Storing
Oaxaca cheese is sold in its characteristic wound balls, fresh, in the refrigerated section of Latin markets and many supermarkets. Keep it wrapped and refrigerated, and use within a week or so. If you can't find it, low-moisture mozzarella is the closest easy substitute.
