Gruyère

Gruyère is a hard, cooked, pressed cow's milk cheese from Switzerland, traditionally made in the canton of Fribourg and surrounding regions. It's aged anywhere from 5 months (mild, called 'doux') to over 12 months (firmer and more crystalline, called 'reserve' or 'vieux'), developing a nutty, slightly sweet flavor with earthy, savory depth as it matures. Unlike Emmental, its holes are small and sparse rather than large and dramatic, and it melts exceptionally smoothly, which is why it anchors classic fondue and gratins.

Varieties

Younger 'doux' Gruyère (aged 5 to 9 months) is mild and creamy, ideal for melting in sandwiches. 'Reserve' or 'vieux' Gruyère (aged over 12 months) develops small flavor crystals, a firmer texture, and a sharper, more concentrated taste, better suited to shaving over dishes or eating on its own than to fondue, where it can turn grainy.

Buying tips

Look for a natural, slightly damp brown rind and a pale ivory interior; avoid pieces with a dry, cracked, or overly yellow surface, which suggests age past its prime or poor storage. Genuine Swiss Gruyère AOP carries a red label with the word 'Gruyère' and a production number stamped into the rind. For fondue, ask for a blend of younger and aged Gruyère to balance meltability with flavor.

Substitutes

• Comté — 1:1

  Also a French Alpine cooked-pressed cheese; very close in nutty flavor and melts just as well.

• Emmental (Swiss cheese) — 1:1

  Milder and slightly more elastic when melted, with larger holes; a good everyday substitute for sandwiches and gratins.

• Beaufort — 1:1

  Firmer and more concentrated in flavor; excellent in fondue but can be harder to find outside specialty shops.

• Jarlsberg — 1:1

  Milder and softer with a buttery sweetness; works in melts but lacks Gruyère's depth in fondue.

• Fontina — 1:1

  Melts beautifully and has a similar nutty-savory quality, though it's slightly funkier and softer in texture.

Storage

Wrap tightly in wax or parchment paper rather than plastic wrap, which traps moisture and encourages mold, then place in a loose plastic bag or container in the warmest part of the refrigerator (usually the door). Properly wrapped, a cut piece keeps for 3 to 4 weeks. Freezing is possible for cooked applications like gratins, but it turns crumbly and loses meltability, so avoid freezing if serving it fresh.

How to use

Grate it for classic Swiss fondue with white wine and a touch of kirsch, melt it over French onion soup, layer it into croque monsieur or a grilled ham and cheese, fold it into quiche or gratin dauphinois, or shave thin slices onto a cheese board with fruit and charcuterie. Because it melts without becoming stringy or oily, it's a reliable choice for baked pasta dishes and savory bread puddings.

What it pairs with

Pairs well with crisp dry white wines like Sauvignon Blanc or a Swiss Chasselas, tart apples and pears, walnuts, and cured meats like prosciutto or dry-cured ham. In cooking, it complements caramelized onions, potatoes, mustard, and ham.

Nutrition

Gruyère is calorie-dense and high in saturated fat and sodium, but it's also a strong source of calcium, protein, and vitamin B12. It's naturally low in lactose due to its long aging, so many people with mild lactose sensitivity tolerate it well.
