Chłodnik: Poland’s Refreshing Cold Beet Soup

Chłodnik, a vibrant pink cold soup based on beets, kefir, and fresh vegetables, is one of Poland’s most distinctive summer dishes. This refreshing, tangy soup offers a perfect antidote to hot weather, combining the earthiness of beets with the cooling properties of fermented dairy and the crunch of fresh cucumbers and radishes. More than just a summer refreshment, chłodnik represents the Polish tradition of fermented foods and seasonal eating.

Historical Background

Chłodnik’s history is intertwined with the broader Eastern European tradition of cold soups, particularly influenced by Lithuanian and Belarusian cuisines. The name “chłodnik” comes from the Polish word “chłodny” (cold/cool), directly indicating the soup’s defining characteristic.

The soup’s origins likely date back several centuries to the Polish-Lithuanian Commonwealth era (1569-1795), when culinary traditions freely mixed across the vast territory. The practice of eating cold soups during summer was widespread among Eastern European peoples, driven by both practical necessity (no need for fire in hot weather) and the refreshing nature of chilled foods.

The key ingredient—fermented dairy—has been central to Polish cuisine for over a thousand years. Before refrigeration, milk was naturally preserved through fermentation, creating products like kefir, buttermilk, and sour milk. These tangy dairy products formed the perfect base for summer soups.

By the 19th century, chłodnik was well-established in Polish cuisine, particularly in eastern regions (present-day Lithuania and Belarus, former Polish territories). The soup appeared in cookbooks as both peasant fare and refined dish for noble tables. While basic versions used simple vegetables and buttermilk, elegant versions might include crayfish, hard-boiled eggs, and dill.

During the communist period, chłodnik was commonly served in milk bars and cafeterias during summer months. The soup’s simple ingredients and no-cooking preparation made it economical and practical. After 1989, chłodnik experienced a renaissance as chefs rediscovered traditional Polish cuisine, and it began appearing on upscale restaurant menus.

Cultural Significance

Chłodnik holds special meaning in Polish summer culinary culture. It’s the quintessential hot-weather dish, embodying the Polish approach to seasonal eating. When temperatures rise, Polish families automatically think of chłodnik as the perfect lunch—cooling, nutritious, and requiring no hot cooking.

The soup represents the Polish tradition of fermented foods, which continues to be valued for both flavor and health benefits. The use of kefir or buttermilk connects chłodnik to centuries of dairy fermentation practices.

In Polish social culture, chłodnik is often served at summer gatherings, garden parties, and outdoor meals. Its vibrant pink color makes it visually striking, while its refreshing nature makes it ideal for warm-weather entertaining. The soup is particularly associated with lazy summer afternoons, vacation cottages, and relaxed outdoor dining.

For older generations of Poles, chłodnik evokes memories of childhood summers spent in the countryside, where grandmothers would prepare large bowls of the pink soup using vegetables fresh from the garden and dairy from local farms.

Traditional Recipe

Ingredients

Main components:

500g (1 lb) young beets with greens
1 liter (4 cups) kefir or buttermilk (or sour milk)
500ml (2 cups) cold water or vegetable broth
1 large cucumber, peeled and diced small
6-8 radishes, thinly sliced
4 hard-boiled eggs
4 spring onions or 1 small regular onion, finely chopped
1 bunch fresh dill, chopped
Juice of 1 lemon
Salt and pepper to taste
Optional: 200ml (3/4 cup) sour cream
Optional: fresh chives for garnish

For serving:

Boiled new potatoes (served warm or cold)
Additional hard-boiled eggs
Ice cubes (optional, for extra chill)

Preparation Steps

Cook the beets: Wash beets thoroughly. If using young beets with greens, separate greens and set aside. Cook whole unpeeled beets in boiling water until tender (30-45 minutes depending on size). Alternatively, roast at 200°C (400°F) wrapped in foil.
Cool and peel: Once beets are cooked, let them cool enough to handle. Peel and grate on a coarse grater or dice into small cubes.
Prepare beet greens (optional): If using young beet greens, wash well, chop finely, and blanch briefly in boiling water (1-2 minutes). Drain and cool.
Create the base: In a large bowl, combine kefir or buttermilk with cold water or broth. Mix well. Add the grated or diced beets along with any beet cooking liquid that’s cooled (this intensifies color and flavor).
Add vegetables: Add diced cucumber, sliced radishes, and chopped spring onions to the bowl.
Add eggs: Peel hard-boiled eggs. Chop 2-3 eggs into small pieces and add to the soup. Reserve remaining eggs for garnish.
Add herbs: Add generous amounts of chopped fresh dill. If you have chives, add them too.
Season: Add lemon juice, salt, and pepper to taste. The soup should be tangy and refreshing. If using sour cream, stir it in now for a creamier texture.
Chill thoroughly: Refrigerate the soup for at least 2-3 hours, ideally 4-6 hours or overnight. Chłodnik must be served very cold.
Serve: Ladle into bowls. Garnish each serving with halved or quartered hard-boiled egg, extra dill, and a small dollop of sour cream. Serve with warm or cold boiled new potatoes on the side or in the soup.

Regional Variations

Different regions of Poland and neighboring countries have developed variations:

Lithuanian Šaltibarščiai: Very similar to Polish chłodnik, often includes sour cream and is sometimes even pinker. Considered a national dish of Lithuania.

Eastern Polish Style: May include chopped beet greens and sometimes kvass (fermented rye drink) for extra tang.

Warsaw Version: Often uses more kefir and less water, creating a thicker, creamier soup.

Silesian Chłodnik: Sometimes adds a small amount of grated horseradish for a subtle kick.

Vegetarian/Vegan: Easily adapted—already vegetarian, can use plant-based kefir for vegan version.

Luxury Version: Some upscale restaurants add crayfish tails, shrimp, or smoked fish.

White Chłodnik: Rare variation without beets, using only cucumber, kefir, and herbs.

Tips for Perfect Chłodnik

Use young beets: Young, fresh beets have the best flavor and color. Avoid large, woody beets.
Don’t skip the chill time: The soup must be thoroughly cold. Overnight refrigeration is ideal.
Quality kefir matters: Use fresh, high-quality kefir or buttermilk. The tangier, the better.
Add ice cubes: On very hot days, add an ice cube or two to each serving for extra refreshment.
Adjust consistency: The soup can be thinner (more water) or thicker (more kefir). Adjust to preference.
Fresh herbs are essential: Dried dill cannot substitute for fresh in this soup.
Balance the tang: Adjust sourness with lemon juice and sweetness with beet cooking liquid.
Prepare ahead: Chłodnik actually improves with a day in the refrigerator as flavors meld.
