Leerdammer — Cups to Grams

Measuring Leerdammer: Cubed, Sliced, and Shredded

Leerdammer density varies substantially with preparation. The difference between shredded and cubed forms is 35 grams per cup — about 35% — a meaningful discrepancy in recipes relying on gram-level precision for baked dishes and cheese sauces.

Cubed, half-inch (135g/cup): The standard cut for cheese boards, pasta dishes, and salads. Half-inch cubes stack efficiently, producing the densest pack of the three forms. A standard 200g retail Leerdammer block yields approximately 1.5 cups cubed.

Sliced, deli-thin (115g/cup): The form most commonly found in pre-packaged retail. Thin slices folded loosely into a measuring cup leave significant air gaps. A typical 200g pack of sliced Leerdammer fills approximately 1.75 cups measured this way.

Shredded (100g/cup): Shredded Leerdammer is the lightest form, as the fine strands create extensive air pockets. Used on pizzas, in quiches, and for gratins. Measure loosely — pressing the cup increases weight by 20-30%.

What Is Leerdammer? Origin and Cheese-Making Process

Leerdammer was created in 1977 in Barendrecht, Netherlands by cheesemaker Cees Boterkooper. The brand is now owned by Bel Group, the French dairy cooperative best known for La Vache qui rit (Laughing Cow). Leerdammer belongs to the Maasdam-style family of Dutch cheeses, named after the River Maas in southern Holland, though Leerdammer itself does not carry the Maasdam PDO designation.

The characteristic large round holes (eyes) in Leerdammer form during a warm-room ripening phase of 3-4 weeks at 20-24°C (68-75°F). During this period, Propionibacterium freudenreichii bacteria consume lactic acid and produce carbon dioxide gas, which accumulates into the distinctive eye formations ranging from 1 to 4 centimeters in diameter. The cheese then undergoes cold storage at 10-12°C for a further 2-4 weeks to develop its final mild, slightly sweet, nutty flavor.

Total aging time is 6-8 weeks, compared to Swiss Emmental at minimum 4 months. This shorter maturation produces Leerdammer's characteristic mildness and creamier texture. Fat content is approximately 45% in dry matter (30-31% total fat), with a moisture content of 37-41%.

Cooking with Leerdammer: Grilled Cheese, Quiche, and More

Leerdammer's melt point of approximately 55-65°C (130-150°F) makes it an outstanding cooking cheese. Its moderate fat content prevents it from becoming greasy, while its semi-hard texture means it holds shape when cold but flows smoothly when heated to the right temperature.

Grilled cheese sandwich: Use 60-80g (approximately half a cup shredded or 4-5 thin slices) per two-slice sandwich. Leerdammer pairs particularly well with sourdough or rye bread. Apply medium-low heat and cover the pan for the first 2 minutes to allow even melting before flipping.

Quiche filling: For a 23cm (9-inch) quiche serving 6-8 people, scatter 150-200g (1.5-2 cups shredded) over the filling ingredients before pouring the custard (4 eggs + 240ml cream + 240ml whole milk). The cheese melts into the custard during baking at 180°C (350°F) for 35-40 minutes.

Fondue variation: Leerdammer combines with Gruyere in equal weights for a milder fondue. For 4 servings: 200g Leerdammer + 200g Gruyere + 200ml dry white wine + 1 tablespoon cornstarch + 1 tablespoon Kirsch. Heat gently to 70-75°C, stirring constantly in figure-eight motions.

Leerdammer vs. Emmental, Jarlsberg, and Baby Swiss

All four cheeses are semi-hard cow's milk cheeses with large holes and mild, nutty-sweet flavor profiles. Understanding their differences helps in substitution decisions and recipe scaling.

Leerdammer vs. Emmental: Emmental is Swiss, aged 4+ months, with a stronger nuttier flavor and slightly drier texture (95-100g/cup grated). Leerdammer is milder and sweeter (100g/cup shredded). In cooking, they substitute 1:1 by weight, but expect more pronounced flavor from Emmental. Emmental's larger wheel size means retail pieces tend to be cut thicker.

Leerdammer vs. Jarlsberg: The most similar pairing. Jarlsberg is Norwegian, slightly tangier and firmer than Leerdammer, with the same characteristic eyes from Propionibacterium. Jarlsberg shreds to approximately 110g/cup versus Leerdammer's 100g/cup. Substitute 1:1 by weight in all applications.

Leerdammer vs. Baby Swiss: American baby Swiss uses small cultures and produces smaller, more numerous holes. The flavor is milder than Leerdammer, the texture slightly softer. Substitute 1:1 by weight; baby Swiss has slightly higher moisture (38-42%) and may release more liquid in cooked applications.

Nutritional Profile and Dietary Considerations

Leerdammer provides approximately 340-360 calories per 100g, with around 26-28g protein, 27-29g fat (17-18g saturated), and less than 1g carbohydrate (residual lactose is minimal in aged cheeses). Calcium content is approximately 800-900mg per 100g, representing 80-90% of the daily value in a single 100g serving.

Per 1 cup cubed (135g): approximately 460-485 calories, 35-38g protein, 36-39g fat. Sodium is relatively moderate compared to many cheeses at approximately 170-200mg per 30g serving, since Leerdammer uses less brine salting than aged hard cheeses or blue cheeses.

Leerdammer, like most aged cheeses, contains negligible lactose — generally well tolerated by lactose-sensitive individuals. It is not suitable for those with cow's milk protein allergies (casein) or following vegan diets. Leerdammer does not contain rennet sourced from animal-free processes in standard commercial production.
