Boerenkass Soup (Dutch Cheese Soup)

Boerenkaas (literally “farmer cheese") soup is the Netherlands’ answer to French onion. A vegetable-based broth made from cauliflower, potato, carrot, and celeriac (the gnarly root vegetable also called celery root) gets ladled into oven-safe bowls, topped with crisp toast and slices of Dutch Gouda, then broiled until the cheese melts and bubbles golden.

Celeriac is the unsung hero. Its earthy celery-and-parsley flavor blends into the broth differently than celery stalks would, contributing depth that pure-vegetable soups often lack. If your store does not carry it, parsnip is the best substitute (sweeter but similar in texture).

Canadian bacon is the closer flavor match to Dutch country ham. It is leaner than American bacon, cured rather than smoked, and brings a meaty note to a dish that would otherwise be entirely vegetable. Place a slice on the toast under the cheese for the proper farmhouse layered effect.

Real aged Gouda matters. The mild, plastic-wrapped grocery store Gouda will work but will not deliver the nutty, sharp edge that aged Boerenkaas Gouda contributes. Look for “Boerenkaas” or “Aged Gouda” at a good cheese counter.

Pair with a glass of dry Dutch beer or apple cider.

Pro Tips

• Cube the vegetables uniformly so they cook in the same fifteen minutes. Different sizes mean some vegetables overcook while others stay raw.
• Use flameproof bowls or crocks. Glass and ceramic vary in heat resistance; check yours before broiling.
• Toast the bread until truly dry and crisp. Soft toast soaks up the broth and disappears under the cheese.
• Watch the broiler closely. Cheese goes from melted to scorched in under thirty seconds.

Variations

• Substitute aged cheddar or Gruyere for the Gouda for a sharper cheese profile.
• Add a sprig of fresh thyme or rosemary to the broth simmer.
• Use pancetta in place of Canadian bacon for an Italian twist.
