Polish Vegetarian Soups: A Seasonal Zupa Jarzynowa Recipe

Zupa jarzynowa is a Polish home-style vegetable soup made with potatoes, root vegetables, and whatever seasonal produce is available, usually in a light broth finished with dill and sometimes cream. This vegetarian version balances tender vegetables with a little richness, and its flexible ingredient list makes it useful for both fresh market vegetables and freezer staples.

Ingredients

2 tablespoons unsalted butter or olive oil (28 g)
1 medium yellow onion, finely diced (about 1 cup; 150 g)
1 small leek, white and pale green parts only, rinsed and sliced (about 1 cup; 120 g)
2 medium carrots, peeled and diced (about 1 cup; 180 g)
1 cup diced celeriac (celery root), peeled (120 g); or use 2 diced celery stalks (about 80 g)
2 cups waxy or all-purpose potatoes, peeled if desired and cut into ½-inch cubes (300 g)
7 cups low-sodium vegetable broth (1.65 L)
1 dried bay leaf
3 whole allspice berries (or ⅛ teaspoon ground allspice, about 0.3 g)
1 teaspoon fine salt (6 g), plus more to taste
¼ teaspoon freshly ground black pepper (about 0.5 g), plus more to taste
1 cup cauliflower florets, cut into small bite-size pieces (200 g)
1 cup green beans, trimmed and cut into 1-inch pieces (120 g)
1 cup frozen peas (145 g)
½ cup heavy cream (120 ml), or ½ cup sour cream (120 g)
⅓ cup finely chopped fresh dill, loosely packed (12 g)
1 tablespoon lemon juice (15 ml), optional

Instructions

Prepare the vegetables. Dice the onion, leek, carrots, celeriac, and potatoes; cut the cauliflower and green beans into bite-size pieces. Rinse the sliced leek well, since grit can collect between its layers. Keep the peas frozen until needed. This preparation takes about 25 minutes, depending on how quickly you work.
Soften the aromatics. Melt the butter in a large, heavy pot or Dutch oven over medium heat. Add the onion and leek and cook for about 4 minutes, stirring often, until softened but not browned. If the pan starts to look dry, lower the heat rather than letting the vegetables catch.
Add the root vegetables and broth. Stir in the carrots, celeriac, potatoes, bay leaf, allspice berries, salt, and pepper. Pour in the vegetable broth and raise the heat until it reaches a gentle boil, which should take about 4 minutes. Avoid a hard rolling boil; it can break up the potatoes before the other vegetables are tender.
Simmer until nearly tender. Lower the heat, cover the pot with the lid slightly ajar, and simmer for 10 minutes. Stir once or twice, scraping the bottom gently. The potato edges should begin to soften, while the pieces should still hold their shape.
Add the quicker-cooking vegetables. Stir in the cauliflower and green beans. Simmer gently for 10 minutes, then add the frozen peas and cook for 2 more minutes. Check a potato and a piece of carrot: both should be tender when pierced, but not falling apart. If they need a little longer, simmer in 2-minute increments.
Finish with cream and dill. Turn the heat to low. Stir a ladleful of hot broth into the cream or sour cream in a small bowl, then slowly stir that mixture back into the pot. This gradual warming helps prevent sour cream from curdling. Add the dill and lemon juice, if using, and warm for about 3 minutes without bringing the soup to a boil.
Season and serve. Remove the bay leaf and, if you can find them, the allspice berries. Taste the broth and adjust the salt, pepper, or lemon. The soup should taste gently savory and fresh, with the dill noticeable but not overpowering. Ladle into warm bowls.

Tips

Cut vegetables to a similar size. Small, even pieces cook at roughly the same rate and are easier to eat from a spoon. Keep the potatoes around ½ inch; much smaller cubes may turn mushy before the carrots soften.
Use a mild vegetable broth. A strongly seasoned or very dark stock can dominate the delicate vegetables and dill. If your broth is salty, begin with less added salt and adjust only at the end.
Choose the right dairy method. Heavy cream can go straight into the soup after tempering, while sour cream benefits especially from being mixed with hot broth first. Keep the soup below a boil after adding either one.
Make it without dairy if needed. Use olive oil instead of butter and omit the cream, or stir in an unsweetened oat or soy cooking cream. Plant-based creams vary in thickness and flavor, so add them gradually and taste before adding lemon.

Serving Suggestions

Serve zupa jarzynowa hot as a light main course or as the first course of a larger meal. A slice of rye bread, crusty sourdough, or a soft bread roll is useful for soaking up the broth. For a more filling lunch, add boiled potatoes or serve the soup alongside a simple cheese sandwich; for a fully dairy-free meal, choose bread without butter or milk in its dough.

A small spoonful of sour cream on each bowl adds a cool, tangy contrast, while extra chopped dill keeps the herbal flavor bright. If the soup tastes especially mild, offer black pepper and lemon wedges at the table so each person can adjust their bowl. Serve promptly after finishing with cream, while the vegetables retain their shape and the broth is hot but not boiling.

Variations

Zupa jarzynowa is a flexible Polish vegetable soup rather than one fixed formula: the vegetables change with the season and what is available. In spring, use young potatoes, asparagus tips, or tender green beans; in summer, add zucchini near the end so it does not turn soft. In colder months, use more root vegetables, such as parsnip or additional celeriac, and reduce the peas if you prefer a less sweet broth.

For a mushroom variation, sauté 200 g (about 7 oz) sliced mushrooms with the onion and leek until their moisture cooks off, then continue with the recipe. They give the broth a deeper, earthier flavor. You can also replace some of the potatoes with 1 cup (about 150 g) diced kohlrabi or add 1 cup (about 150 g) shredded cabbage with the cauliflower. If using a firmer vegetable, cut it small and check its tenderness before serving.

To make a more substantial bowl, stir in 1 cup (about 150 g) cooked white beans during the final 5 minutes, or add cooked barley. These are optional additions rather than requirements; barley will absorb broth as it sits, so you may need to thin leftovers with a splash of water or stock. For a lighter, dairy-free finish, skip the cream and add a little extra dill and lemon instead.

Storage and Reheating

Let the soup cool briefly, then refrigerate it in shallow, covered containers within 2 hours of cooking. Keep it refrigerated at 40°F (4°C) or below and use it within 3–4 days. The potatoes and vegetables continue to soften as they sit, so the texture will be softer on the second day. If you know you plan to freeze portions, freeze the soup before adding cream or sour cream; dairy can separate or become grainy after thawing.

Freeze cooled soup in airtight freezer containers, leaving a little room for expansion, for up to 2–3 months for best quality. Thaw it overnight in the refrigerator, then warm it gently in a saucepan, stirring occasionally. Reheat leftovers to 165°F (74°C), checking with a food thermometer. Add the cream and fresh dill after reheating, and do not repeatedly cool and reheat the same pot; warm only the portion you plan to eat.

Frequently Asked Questions

Is zupa jarzynowa always vegetarian?
Not necessarily. Home versions vary, and some use meat stock or meat additions. This recipe uses vegetable broth and no meat, so it is vegetarian as written. Check the label on packaged broth, and choose a vegetable-based option if you are avoiding meat ingredients.

Can I use frozen vegetables?
Yes. Frozen peas can go straight into the pot, as directed. Frozen green beans or cauliflower also work; add them near the end and allow a few extra minutes if needed. Frozen vegetables can release water and soften faster than fresh ones, so check them regularly and avoid prolonged boiling.

What can I use instead of celeriac?
Use two celery stalks for a practical substitute. Celeriac has a more concentrated, earthy celery flavor and a firm texture; ordinary celery is milder and adds a little less body. Parsnip can also work, though it makes the soup sweeter, so start with a smaller amount if you want to keep the flavor balanced.

Can I make this soup ahead?
Yes. Cook the soup through the vegetable simmering steps, then cool and refrigerate it promptly. Reheat it the next day to 165°F (74°C), then temper and add the cream, dill, and lemon. This keeps the dairy fresher in flavor and gives you more control over the vegetables’ final texture.

Why did my cream curdle?
The soup was likely too hot when the dairy went in, or the dairy was added cold all at once. Lower the heat, mix a little hot broth into the cream first, and stir that warmed mixture into the pot. Afterward, heat gently without boiling. If it has already separated, the soup is generally still usable, though its texture may be less smooth.
