Leerdammer and Maasdam are Dutch holey cheeses often confused with each other. Here's how they relate and what sets them apart.
Leerdammer and Maasdam are two Dutch cheeses that look almost identical — pale, holey, and Swiss-like — and they're frequently confused. Understanding how they relate clears up the mix-up: one is a brand, the other a cheese type, and together they form a popular family of mild, nutty Dutch cheeses.
The Key Distinction: Brand vs. Type
The simplest way to understand these two is that Maasdam is the name of a cheese type, while Leerdammer is a specific brand of that style. Maasdam is a Dutch cheese developed in the 20th century as a more affordable, faster-maturing alternative to Swiss Emmental, with similar large holes and a sweet, nutty flavor. Leerdammer is a well-known commercial brand of Maasdam-style cheese. So all Leerdammer is Maasdam-style, but not all Maasdam is Leerdammer.
What Maasdam Is
Maasdam is a semi-hard Dutch cow's-milk cheese created to capture the appeal of Swiss-style cheeses in a Dutch product. Like Emmental and Jarlsberg, it uses propionic acid bacteria that produce carbon dioxide during ripening, forming the large round holes. It matures relatively quickly, which made it economical, and it became popular as a mild, nutty, holey everyday cheese.
Why They Have Holes
Both Leerdammer and Maasdam owe their large holes to the same process used in Swiss-style cheeses. Specific bacteria added during production release carbon dioxide gas as the cheese ripens, and the gas collects into bubbles within the supple paste, forming the characteristic round "eyes." The holes are a signature of the Maasdam style and a key part of its Swiss-like appearance.
Flavor and Texture
Maasdam and Leerdammer are semi-firm, smooth, and supple, pale yellow, with large holes. The flavor is mild, sweet, and nutty, similar to a gentle Emmental or Jarlsberg, with a buttery character and a clean finish. They're approachable, crowd-pleasing cheeses without sharpness or pungency, which makes them popular for everyday eating and for those who prefer mild cheeses.
How to Use Them
Both are versatile, mild cheeses. They slice neatly for sandwiches and snacking, melt smoothly for toasties, gratins, and cooking, and make a friendly addition to a cheese board with fruit and bread. Their nutty sweetness and good melt make them easy substitutes for Emmental or Jarlsberg in many uses, from breakfast slices to melted dishes.
Pairings
Leerdammer and Maasdam pair with crisp white wines, light reds, and lagers, as well as with fruit like apples and grapes, nuts, and crusty bread. Their mild, nutty flavor makes them easy to match for both snacking and cooking.
Buying and Storing
Maasdam is sold under various brands, including Leerdammer, in blocks, wedges, and slices. Store it wrapped in the fridge and use within a couple of weeks. Slice or grate it fresh for the best flavor and melt.
