Finnish Summer Vegetable Soup (Kesäkeitto): A Taste of Nordic Sunshine

I remember the first time I tasted kesäkeitto. I was visiting my husband’s family in Finland, a place of endless summer days and cozy, light-filled evenings. His äiti (mother) served a steaming bowl of this pale, unassuming soup. One spoonful, and I was transported. It was the taste of sunshine in a bowl – sweet, fresh, and utterly comforting, a symphony of the season’s bounty. It has since become a summer staple in my own kitchen, a reminder of long days and cherished family memories.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 15-20 minutes
• Total Time: 30-35 minutes
• Servings: 4-6
• Yield: About 8 cups
• Dietary Type: Vegetarian (Can be made vegan by substituting the milk and cream)

Ingredients

• 2 cups water
• 2 small carrots, sliced
• 1 medium potato, cubed
• ¾ cup fresh green peas or ¾ cup frozen green peas
• 1 cup cut fresh green beans or 1 cup frozen green beans
• ¼ small cauliflower, separated into florets
• 2 ounces fresh spinach, cut up (about 2 cups)
• 2 cups milk (dairy or non-dairy)
• 2 tablespoons all-purpose flour (or gluten-free alternative)
• ¼ cup whipping cream (or vegan alternative)
• 1 ½ teaspoons salt
• ⅛ teaspoon pepper
• 2 tablespoons snipped dill weed or 2 tablespoons parsley

Equipment Needed

• 3-quart saucepan
• Measuring cups and spoons
• Knife and cutting board

Instructions

1. In a 3-quart saucepan, bring the water, carrots, potato, peas, green beans, and cauliflower to a boil over medium-high heat.
2. Once boiling, reduce the heat to low. Cover the saucepan and simmer until the vegetables are almost tender. This usually takes 10 to 15 minutes. Check the vegetables for doneness by piercing them with a fork; they should be easily pierced but still retain a slight bite.
3. Add the cut-up spinach to the saucepan. Cook uncovered for about 1 minute, or until the spinach has wilted.
4. In a small bowl, mix ¼ cup of the milk with the all-purpose flour until a smooth slurry forms. This prevents lumps from forming when added to the hot soup.
5. Gradually stir the milk and flour mixture into the vegetable mixture in the saucepan. Make sure to stir constantly to prevent the flour from settling and burning on the bottom of the pan.
6. Bring the soup back to a boil over medium heat, stirring constantly. Boil and stir for 1 minute, or until the soup has thickened slightly.
7. Stir in the remaining milk, the whipping cream, salt, and pepper.
8. Heat the soup just until hot. Do not boil after adding the milk and cream, as this can cause the milk to curdle.
9. Garnish each serving with snipped dill weed or parsley before serving.

Expert Tips & Tricks

• Fresh is best: Using fresh, seasonal vegetables will give the soup the best flavor. Visit your local farmer’s market for the most vibrant ingredients.
• Don’t overcook the vegetables: The vegetables should be tender-crisp, not mushy. Overcooked vegetables will lose their flavor and texture.
• Adjust the thickness: If you prefer a thicker soup, use a little more flour in the slurry. For a thinner soup, use less.
• Make ahead: The soup can be made a day ahead and stored in the refrigerator. The flavors will meld and deepen overnight.
• Vegan variation: Easily make this soup vegan by using plant-based milk (such as oat or almond milk) and a plant-based cream alternative. A touch of nutritional yeast can add a subtle cheesy flavor.
• Seasoning is key: Taste and adjust the seasoning as needed. A squeeze of lemon juice can brighten the flavors.

Serving & Storage Suggestions

Serve kesäkeitto hot, garnished with fresh dill or parsley. It’s traditionally served with freshly-baked Finnish Rye Bread and a slice of mild cheese, such as leipäjuusto (Finnish squeaky cheese), for a complete and satisfying lunch or light dinner.

• Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days.
• Reheating: Reheat the soup gently over low heat on the stovetop, stirring occasionally, until heated through. Avoid boiling.
• Freezing: While not ideal due to the dairy content, the soup can be frozen. Be aware that the texture of the vegetables may change slightly upon thawing. Thaw overnight in the refrigerator and reheat gently.
