Halloumi is a semi-hard, brined cheese from Cyprus, best known for its unusually high melting point, which allows it to be grilled or pan-fried without losing its shape. Made from a blend of sheep’s, goat’s, and cow’s milk, it has a firm, springy texture and a salty flavor that intensifies when cooked. In 2021, the European Union granted halloumi Protected Designation of Origin (PDO) status, meaning only cheese produced on the island of Cyprus using the traditional recipe can legally be sold as halloumi in the EU.
How Halloumi Is Made
The production process is what gives halloumi its distinctive character. Milk is gently heated to about 32°C (90°F) and mixed with rennet to form curds, which are then pressed into blocks. What happens next sets halloumi apart from most cheeses: the pressed blocks are cooked in hot whey at roughly 97°C (206°F) for about an hour. This step changes the protein structure of the cheese, giving it that signature squeaky texture and high heat tolerance.
Once the cheese floats to the surface of the whey, each piece is removed, coated in salt and dried mint leaves, and folded in half while still hot. The mint isn’t just decorative. Traditionally, it acted as a natural preservative, and it contributes a subtle herbal note to the finished cheese. That folded-over shape you see in the package is a hallmark of authentic halloumi.
What’s in the Milk Blend
Traditional halloumi relies on sheep’s and goat’s milk, which give the cheese a richer, more complex flavor than cow’s milk alone. Under the PDO specification, the quantity of sheep or goat’s milk (or a blend of the two) must always exceed the amount of cow’s milk used. This requirement has been a point of contention on the island, since many large-scale producers had shifted toward cheaper cow’s milk over the decades. Cyprus has granted transitional periods for producers to adjust their herds and sourcing to meet the standard.
Halloumi made entirely from sheep’s and goat’s milk tends to be creamier, with a slightly more tangy, complex flavor. Versions with more cow’s milk are milder and firmer. If you’re buying halloumi outside of Cyprus, check the label for milk composition, as non-PDO versions may use cow’s milk exclusively.
Nutrition at a Glance
Per 100 grams, halloumi contains roughly 305 calories, 20.5 grams of protein, and 24.6 grams of fat. It’s an excellent source of calcium at 700 mg per 100 grams, which is about 70% of the typical daily recommendation. The standout number to be aware of is sodium: 1,100 mg per 100 grams, which is high even by cheese standards. A single 80-gram serving delivers close to half the recommended daily sodium limit for most adults.
If sodium is a concern, soaking halloumi slices in plain water for 30 minutes before cooking pulls out a noticeable amount of salt. This won’t eliminate it, but it takes the edge off. The high protein content and satisfying texture make halloumi a popular meat substitute for vegetarians. Most commercial halloumi is made with vegetarian or microbial rennet rather than animal-derived rennet, though it’s worth checking the packaging if this matters to you.
Why It Doesn’t Melt
Most cheeses soften into a puddle on a hot pan. Halloumi holds its shape because of that unusual cooking step during production. Heating the curds in near-boiling whey denatures the proteins in a way that raises the cheese’s melting point well above normal cooking temperatures. The result is a cheese you can sear in a skillet, lay on a grill grate, or even deep-fry, and it will brown and blister on the outside while staying intact inside. It softens and becomes more pliable with heat, but it won’t run.
How to Cook and Serve It
The simplest approach is the best one. Slice halloumi into pieces about 1 cm thick and cook them in a dry, hot pan or on a grill. No oil is needed since the cheese releases enough fat on its own. Give each side one to three minutes until golden brown and blistered. Eat it right away, because halloumi firms back up and becomes rubbery as it cools.
A squeeze of lemon juice right after cooking brightens the flavor and cuts through the saltiness. In Cyprus, one of the most traditional pairings is halloumi with fresh watermelon. The sweetness of the fruit balances the salt of the cheese in a way that sounds odd but works beautifully, especially in summer. Halloumi also goes well stuffed into pita bread with fresh vegetables and tzatziki, crumbled over salads, or served alongside cured pork loin (a Cypriot pairing known as halloumi with lountza).
Beyond grilling, you can cube halloumi and thread it onto skewers with vegetables, slice it into stir-fries during the last minute of cooking, or bake it in the oven at high heat until it puffs slightly and turns golden.
Storage and Shelf Life
Unopened vacuum-sealed halloumi keeps for four to six months in the refrigerator, according to most Cypriot producers. Research on shelf life found that at a steady 5°C (standard fridge temperature), vacuum-packaged halloumi stays in good condition for roughly 80 days. That window shrinks dramatically with temperature: at 15°C it drops to about 38 days, and at room temperature it lasts only a few days before spoiling.
Once you open the package, store leftover halloumi submerged in its brine (or lightly salted water) in an airtight container in the fridge. This keeps it from drying out and extends its usable life by a couple of weeks. If there’s no brine left, wrapping it tightly in plastic wrap works for a few days, but the texture will start to suffer. Halloumi also freezes well for up to three months. Thaw it in the fridge overnight before cooking.
