Traditional Finnish Pea Soup (Hernekeitto) with Smoked Ham (28g Protein)

Published: 8/31/2026

Traditionally served on Thursdays in Finland, Hernekeitto is a thick, satisfying soup made from dried yellow peas. Generous helpings of lean smoked ham provide a significant protein boost and a deep, smoky undertone.

Ingredients (6 servings)

• 1 lb (450 g) dried yellow peas, soaked overnight
• 1 lb (450 g) lean smoked ham, diced
• 8 cups (1.9 L) water
• 1 large onion, finely chopped
• 1 tbsp (15 g) yellow mustard (plus more for serving)
• 1 tsp (2 g) dried marjoram

Instructions

1. Drain the soaked peas and place them in a large soup pot with 8 cups (1.9 L) of fresh water.
2. Add the diced ham and chopped onion.
3. Bring to a boil, then reduce the heat to a low simmer. Cook for 2.5 to 3 hours, stirring occasionally, until the peas have broken down into a thick, smooth puree.
4. Stir in the dried marjoram and 1 tablespoon of mustard.
5. Serve hot with an extra dollop of mustard on top.

Pro Tips

• Texture Mastery: This soup is often better the next day as the flavors mature and the texture thickens; simply thin it with a little broth or water when reheating.
• Nutritional Benefit: Dried yellow peas are a powerhouse of plant-based protein and fiber, promoting long-lasting satiety and digestive health.
