Finnish Summer Vegetable Soup

The first time I encountered Finnish summer soup was during a unexpectedly cool July evening at my friend Minnas cottage by the lake. She kept insisting this humble vegetable soup was somehow magical, and watching her chop the garden fresh vegetables with such care made me curious. When we finally sat down to eat, I understood what she meant

Last summer I made this for my family using vegetables from our first real garden attempt. The kids who normally reject anything green went back for thirds, and my grandmother asked for the recipe before leaving the table

Ingredients

• New potatoes: Their waxy texture holds up perfectly in soup, unlike russets which would fall apart completely
• Fresh dill: This is nonnegotiable for authentic Finnish flavor, add it right at the end so it stays bright
• Whole milk and cream: The combination creates richness without being overwhelming, you can adjust the ratio to your taste
• White pepper: Traditional in Scandinavian cooking, it adds gentle heat without visible specks in the pale broth
• Seasonal vegetables: The beauty of this soup is adapting it to whatever your garden or market offers

Instructions

Start the broth:

Bring your water or vegetable broth to a gentle boil, then add the potatoes, carrots, and cauliflower first since they need the longest cooking time

Add remaining vegetables:

Toss in the green beans, peas, leek, and radishes, cooking just until everything is tender but still has some bite

Make the roux:

Melt butter in a small saucepan, stir in the flour and cook for exactly one minute while constantly stirring

Create the creamy base:

Gradually whisk in the milk until smooth, then let it thicken before combining with the vegetables

Finish and serve:

Pour in the cream, season with salt and white pepper, and stir in fresh dill just before serving

This soup became my goto recipe last summer when my garden produced more vegetables than we could eat raw. Even my vegetable hating husband started requesting it on cool evenings

Making It Your Own

The traditional Finnish version is beautiful as written, but I have discovered that adding a handful of baby spinach at the end creates gorgeous color variation. Sometimes I throw in chopped chives too for an extra layer of onion flavor

What To Serve Alongside

My Finnish friend always serves this with dark rye bread or crispy knäckebrød. The slight bitterness of rye balances the creamy sweetness of the soup perfectly, and a simple green salad with vinaigrette cuts through the richness

Storage And Make Ahead Tips

This soup actually tastes better the next day as flavors meld together, but hold off on adding the final cream and dill until you reheat it. The roux thickened base will keep well in the refrigerator for up to three days

• Freeze the vegetable base without cream for up to two months
• Add cream and dill after reheating to prevent separation
• Thin with extra milk or broth if it gets too thick overnight

Save

Theres something deeply comforting about a soup that celebrates vegetables without trying to hide them. This Finnish summer soup has become a permanent fixture in my kitchen, and I hope it finds a place in yours too
