Dutch Pea Soup

Erwtensoep, or snert, is the Dutch winter soup so traditional that there’s an unofficial rule: it’s thick enough when a spoon stands upright in the bowl. Two cups of split peas simmer for 10 long hours with ham, leeks, celery, and carrot until the peas dissolve entirely into a thick, almost porridge-like soup with no need for cream or thickener.

The overnight rest in the fridge isn’t optional, it’s tradition. As the soup cools, the starches release further and the flavors marry. Reheated the next day, the soup is thicker, deeper, and even more satisfying than the night it was made. Skip this and you’ve made decent pea soup; honor it and you’ve made proper snert.

Leeks instead of regular onions are the Dutch touch. Their gentler sweetness lets the smoky ham and split peas dominate without competing.

Kitchen Tips

• No need to soak the split peas ahead, they break down beautifully on their own during the long cook
• Use a smoked ham hock or ham bone for the deepest flavor, then shred the meat back into the soup at the end
• Stir occasionally on the stovetop or use a slow cooker, scorched peas on the bottom can ruin the pot
• Thin with a splash of water or stock when reheating, the soup thickens significantly overnight
• Serve with thick slices of buttered rye bread and a dab of mustard, the Dutch way

Variations

• Add sliced smoked sausage (rookworst is traditional) in the last 30 minutes
• Substitute yellow split peas for green for a different look and slightly milder flavor
• Stir in a tablespoon of fresh thyme or a bay leaf for herbal warmth
