Kohlrabi potato soup recipe

Updated potato soup dish.

Have you ever had kohlrabi? It’s a sweet but slightly peppery vegetable, similar to a turnip, that is part of the cabbage family. The root vegetable pairs well with another root vegetable – you guessed it – the potato. Give this recipe a try for dinner tonight. 

Serves 6-8


  • 1 tablespoon olive oil
  • 1 medium sweet onion, chopped
  • 1-2 cloves of garlic, pressed/minced
  • 1 pound kohlrabi bulb, leaves and skin removed, diced into ½ inch cubes or smaller* 
  • ½ - 1-pound red potato, diced into ½ inch cubes or smaller
  • 4 cups low-sodium broth (chicken or vegetable)
  • 1 2/3 cup milk (or unsweetened milk alternative, soy, almond, cashew, etc.)
  • 1-2 bay leaf
  • ½ teaspoon dried thyme
  • ¼ teaspoon pepper
  • ¼ teaspoon salt
  • 1/8 teaspoon red pepper flakes, optional
  • *You may substitute a turnip if kohlrabi is unavailable.

Optional ingredients

  • 1 ½ cups fresh or canned mushrooms, trimmed and cut into bite size pieces
  • ¼ - ½ cup lentils, rinsed
  • Carrots, peeled and sliced/diced

Optional toppings

  • Shredded cheese
  • Plain non-fat Greek yogurt or sour cream
  • Chopped chives, fresh parsley or preferred herb


In a large pot, heat oil over medium heat, sauté onion until tender and translucent. Add garlic and cook until fragrant. Add kohlrabi, potatoes, broth, milk, bay leave, thyme, salt, pepper and optional red pepper flakes. If using anything from the optional ingredients list, add them now.

Turn heat to medium-high and cover. Simmer for about 15-20 minutes, or until vegetables are fork tender.

Mix well. Remove bay leaf and serve in bowls and add optional toppings.

Optional: Puree soup until smooth.
