Ingredients

Scale

Vegetables

  • 4 medium potatoes, peeled and diced
  • 1 cup green cabbage, finely chopped
  • 1 cup kale, stems removed and chopped
  • 1 medium leek, sliced
  • 1 onion, diced
  • 2 green onions, sliced for garnish

Liquids

  • 3 cups vegetable broth
  • 2 cups milk (or plant-based milk)

Dairy & Fats

  • 4 tablespoons butter (or vegan substitute)

Seasonings

  • Salt and pepper to taste
  • ½ teaspoon nutmeg

Instructions

  1. Sauté the aromatics: In a large pot, melt the butter over medium heat. Add the diced onion and sliced leek, sautéing until they become soft and translucent, about 5 minutes, to develop their sweet, mellow flavors.
  2. Add potatoes and cook briefly: Add the diced potatoes to the pot, stirring and cooking them for an additional 3 minutes to lightly coat them in butter and aromatics before adding liquid.
  3. Simmer with broth and greens: Pour in the vegetable broth and bring the mixture to a boil. Then reduce the heat to low and add the chopped cabbage and kale. Let it simmer gently for 15-20 minutes until the potatoes are tender and the greens are softened.
  4. Puree the soup: Using an immersion blender, carefully puree the soup until smooth. If you prefer, leave a few potato chunks for added texture.
  5. Finish with milk and seasoning: Stir in the milk and season the soup with salt, pepper, and nutmeg. Heat gently for about 5 minutes until warmed through, without boiling, to keep the milk from curdling.
  6. Serve: Ladle the warm soup into bowls and garnish with sliced green onions for a fresh, mild bite.

Notes

  • You can substitute plant-based milk and vegan butter to make this recipe vegan-friendly.
  • For a richer soup, use whole milk or half-and-half.
  • To vary the greens, try substituting kale with spinach or Swiss chard.
  • Leftovers can be refrigerated for up to 3 days and reheated gently on the stove.
  • Adjust seasoning with more salt and pepper as needed after blending.
