Kulajda (Czech Mushroom Soup Recipe) (2024)

Published: Oct 17, 2022 · Modified: Jun 19, 2023 by Faith · This post may contain affiliate links · 1 Comment

Kulajda is a thick and creamy Czech mushroom soup with potatoes and dill. It has a well-balanced sweet and sour flavor profile similar to Borscht. And it’s quick and easy to make in just 30 minutes!

I first had Kulajda Polévka in Prague a couple years ago. It was a cool late-July day and I ate it at an outdoor café. I enjoyed every moment, especially being surrounded by such lovely, unique architecture!

(If you're interested, you can check out beautiful Prague in this post, and see more Czech food in this post.)

This classic Czech soup originates in the highly forested areas of south Bohemia where mushrooms grow in abundance. Mushrooms and potatoes are the main vegetables in this dish, and dill adds fresh brightness at the end. This soup has a sweet/sour flavor thanks to a blend of vinegar and sugar, which you’ll love if you enjoy Borscht.

Like a lot of regional specialties, there are many variations of this dish.

I’ve seen darker versions that use beef broth and dried mushrooms. And there are lighter versions that use chicken broth and fresh mushrooms. Sometimes this soup is pureed until velvety smooth, and other times it has a chunky texture. I've also had this soup when it was silky smooth except for mushroom pieces. There is a lot of leeway for you to interpret this recipe how you want, and to truly customize it to make it your own.

When I had this soup in Prague, it had a poached egg on top. This adds protein to make it more of a filling meal, as there typically isn’t meat in the soup. Also, the runny yolk adds another layer of flavor and texture to the dish.

• Chicken stock, vegetable stock, or beef stock
• Potatoes
• Salt and black pepper
• Allspice
• Bay leaf
• Heavy whipping cream
• White wine vinegar
• Sugar
• Fresh dill

Step-by-Step Instructions

1. Add the butter to a 5-quart pot over medium to medium-high heat. Once it’s starting to melt, stir in the onion and mushrooms. Cook 5 minutes, stirring frequently.
2. Turn the heat down to medium and stir in the flour. Cook 30 seconds, stirring constantly.

Bring up to a boil, and then cover the pot, turn the heat down slightly so it doesn’t boil over, and cook until the potatoes are tender, about 10 minutes, stirring occasionally. (During this time I like to make the poached eggs.)
4. Remove from the heat and stir in the cream, vinegar, sugar, and dill. Serve each bowl of soup topped with a poached egg and ½ teaspoon of fresh dill sprinkled on top.

Mushrooms in the Czech Republic

Foraging for mushrooms is a common practice and almost a hobby in the Czech Republic.

They have some incredibly beautiful forests, which are home to many different kinds of fungi, both edible non-edible. Mushrooms are so beloved that very Czech family picks over 8 kilograms (over 17 pounds) of mushrooms per year!

A few common types of edible mushrooms found in the Bohemian Forest along the border of Germany and Czechia include: Boletus edulis, which are also known asporcini, cep, penny bun mushrooms, or Steinpilz, as well as chanterelle mushrooms and parasol mushrooms.

One way of preserving all their beautiful mushrooms is to dry them. And dried mushrooms make a lovely Kulajda!

What Type of Fresh Mushrooms to Use for Kuladja

For this soup, you can use a mix of whatever type of fresh mushrooms you have available locally. I used a combination of shiitake mushrooms and cremini mushrooms.

How to Use Dried Mushrooms Instead of Fresh in Soup

Dried mushrooms are frequently used to make traditional Czech Kulajda. They work very well and yield a rich-colored, mushroom-flavored stock.

To use dried mushrooms in this dish:

1. Omit the fresh mushrooms. You will need 1 ounce of dried mushrooms (such as porcini) instead of 8 ounces of fresh mushrooms.
2. Rehydrate the dried mushrooms. You can do this in 1 of 2 different ways: 1) add the dried mushrooms and 2 cups of boiling water to a bowl large bowl and soak for 1 hour (or up to 12 hours), or 2) add the dried mushrooms and 2 cups of boiling water to a saucepan, bring to a boil, cover the saucepan and turn the heat down a little so it doesn’t boil over, and boil for 15 minutes.
3. Use the mushroom soaking liquid in the soup. For deep mushroom flavor, you can use the 2 cups of mushroom soaking liquid to make the soup and reduce the amount of chicken stock by 2 cups.

What Type of Potatoes to Use for Czech Mushroom and Potato Soup

Really, any type of potatoes will work for Kulajda. I prefer not to use russet potatoes or other starchy potatoes here because they will disintegrate and fall apart in the soup. (There’s nothing wrong with that, it’s just a matter of personal preference.)

Instead, I like to use white potatoes, which have white flesh and light tan-colored skin. These are considered an all-purpose potato. They’re great for mashing and also hold their shape well, which makes white potatoes a good choice for soups and potato gratins.

If white potatoes aren’t available, I like to use waxy potatoes, such as Yukon Gold. This type of potato also holds its shape well in soups.

How to Make Poached Eggs

1. First, fill a shallow saucepan with 2 to 3 inches of water and bring to a boil.
2. Next, add ½ tablespoon distilled vinegar or apple cider vinegar, and turn the heat down to medium to medium-low so it’s simmering.
3. Then crack each egg into a small bowl 1 at a time, and gently slip the egg into the water.
4. Finally, cook until the eggs reach your desired level of runniness, about 3 minutes.
5. Lastly, remove the eggs with a slotted spoon, patting the bottom with paper towels to absorb the liquid.
