Finnish Summer Vegetable Soup

Summer in Helsinki taught me that some of the best cooking happens when you barely cook at all. I stumbled into a tiny kitchen apartment after years of heavy stews and roasting everything to oblivion, and my Finnish neighbor handed me a bag of vegetables from her garden. She told me kesäkeitto was what her grandmother made when the kitchen got too hot to turn on the oven, and that first spoonful changed how I thought about soup entirely.

Last July, I made this for friends who claimed they hated vegetable soup. They watched me dump in peas and beans and cauliflower, looking doubtful about the whole operation. But then the smell of dill hit the kitchen, and someone actually reached for a spoon before I even finished seasoning.

Ingredients

• New potatoes: These hold their shape beautifully and bring a subtle sweetness that russets never could, plus the thin skins mean less prep work
• Fresh dill: The soul of Finnish cooking and what makes this soup taste like summer rather than just vegetables in cream
• Heavy cream and milk: The combination creates richness without being overwhelming, and I learned the hard way that skipping the cream makes all the difference
• Seasonal vegetables: Carrots, cauliflower, green beans, and peas form the classic quartet, but honestly whatever looks good at the market works wonderfully

Instructions

Start the vegetable base:

Bring your broth to a gentle bubble and drop in the potatoes, carrots, and cauliflower first, giving them about 8 minutes to get a head start while the kitchen starts smelling wonderful.

Add the quick-cooking vegetables:

Toss in the green beans, fresh peas, leek, and those pretty radish slices, letting everything swim together for another 7 to 8 minutes until tender but still holding their shape.

Build the creamy foundation:

Melt butter in a separate pan, whisk in flour until it forms a loose paste, then gradually stream in milk while stirring until it thickens into something velvety.

Bring it all together:

Pour that silky milk mixture and cream into your vegetable pot, stirring gently to marry everything without breaking up the tender pieces you just cooked.

Finish with finesse:

Season with salt and white pepper, then fold in the fresh dill right at the end so it stays bright and fragrant, tasting as you go.

My friend Elina once told me that kesäkeitto tastes better when someone else makes it for you, sitting at a wooden table with bread and butter. I think she was right about the company part, but there is something deeply satisfying about watching those vegetables dance in the cream, knowing dinner is ready in under an hour.

Choosing Your Vegetables

The beauty of this soup lies in using whatever looks freshest at the market, though I have found that some vegetables work better than others. Root vegetables need more time, while delicate things like peas and green beans only want a quick swim. Trust your instincts and bite into a piece if you are unsure about doneness.

Making It Your Own

Finnish cooks will tell you there are a thousand ways to make kesäkeitto, and most of them are probably right. I have added baby spinach at the end for color, swapped in almond milk successfully, and even tossed in corn kernels when fresh corn was calling my name. The soup remains forgiving as long as you respect the gentle cooking times.

Serving Suggestions

Traditional Finnish rye bread is the perfect companion, its earthy flavor balancing the creaminess perfectly. A crisp green salad on the side makes it feel more like dinner than a starter, and for a cozy weekend lunch, some smoked salmon or pickled cucumbers on the plate would not be out of place.

• Let the soup rest for five minutes before serving, allowing the flavors to settle and the temperature to become perfect
• Keep extra dill on hand because the bright green against the pale cream is almost too pretty to stir in
• This soup keeps beautifully for a day or two in the refrigerator, though the dill will fade slightly

There is something timeless about a soup that celebrates vegetables exactly as they are, letting their natural sweetness shine through. That first bowl of kesäkeitto in my borrowed Finnish kitchen remains one of my favorite food memories, simple and perfect and full of light.

Recipe Questions & Answers

→ What vegetables are traditionally used in Kesäkeitto?

Traditional Kesäkeitto includes new potatoes, carrots, cauliflower florets, green beans, fresh peas, and leeks. Some variations add radishes for extra crunch and color. The key is using vegetables that are in season during Finnish summers, creating a medley of textures and sweetness that pairs beautifully with the creamy broth.

→ Can I make this soup dairy-free or vegan?

Absolutely. Substitute the butter with plant-based butter or olive oil, replace whole milk with unsweetened almond or oat milk, and use coconut cream or a vegan cream alternative in place of heavy cream. The roux can be made with gluten-free flour blend to keep it entirely plant-based while maintaining the soup's characteristic silky texture.

→ Why is white pepper used instead of black pepper?

White pepper is traditional in Finnish cooking because it provides the pepper's warmth without visible specks in the light-colored soup. It has a slightly milder, more earthy flavor profile than black pepper, which complements the delicate vegetables without overpowering their natural sweetness. If you only have black pepper, use sparingly to maintain the soup's gentle flavor balance.

→ What should I serve with Kesäkeitto?

Traditional Finnish accompaniments include dense rye bread or crispy crispbread (knäckebröd), which provide hearty texture contrast to the smooth soup. A simple green salad with vinaigrette balances the richness. For a complete meal, consider adding grilled fish or pickled herring on the side, following authentic Finnish dining customs.

→ How long does Kesäkeitto keep and can it be frozen?

Kesäkeitto stores well in the refrigerator for 3-4 days, though the vegetables may soften slightly upon reheating. Freezing is possible but may affect the creamy texture—the dairy can separate when thawed. If freezing, omit the cream and add it fresh when reheating. Reheat gently over low heat, stirring occasionally to maintain the smooth consistency.

→ Can I adjust the vegetables based on what's available?

Yes, Kesäkeitto is wonderfully adaptable based on seasonal availability. Swap cauliflower for broccoli, add zucchini or summer squash during peak season, or incorporate turnips for extra earthiness. The key is maintaining a mix of root vegetables for body and quicker-cooking vegetables for texture. Keep the total vegetable quantity similar to ensure proper broth-to-vegetable ratio.
