Romanian Leek Soup – Vegan Ciorbă de Praz de Post with Fresh Chives

Romania – A Country of Hearty Soups and Culinary Traditions
Romanian cuisine is shaped by regional traditions, seasonal vegetables and influences from the Balkans, Central Europe and the Ottoman world. Soups are an important part of everyday food culture, particularly ciorbă, a family of soups known for their pleasantly tangy flavour. Fresh herbs such as lovage and parsley, root vegetables and homemade vegetable broths give these dishes their distinctive character. Orthodox Christian fasting traditions have also influenced Romanian cooking, inspiring a rich variety of naturally plant-based dishes.

What Is Ciorbă de Praz de Post?
Ciorbă de praz de post is a Romanian fasting-style leek soup. The word "praz" means leek, while "de post" indicates a dish prepared according to religious fasting traditions, generally without meat, dairy products or eggs. Traditional versions combine tender leeks, root vegetables, vegetable broth and fresh herbs, often finished with a pleasantly sour note. My Via Veggie Vegan version uses lemon juice, a little plant-based sour cream for creaminess and fresh chives for a colourful finish. The soup is entirely plant-based and inspired by Romania's tradition of simple, nourishing fasting dishes.

▣ Ingredients (2 servings)

  • 2 leeks, white and light green parts, approximately 350 g
  • 1 carrot
  • 1 small parsley root or 80 g celeriac
  • 1 yellow onion
  • 2 tbsp tomato paste
  • 1 pinch kala namak
  • 6 sprigs fresh chives
  • 2 tbsp freshly squeezed lemon juice
  • 3 tbsp vegan sour cream, for the soup
  • 2 tbsp vegan sour cream, for the garnish
  • 1 tsp cornstarch
  • 2 tbsp cold water
  • to taste salt & freshly ground black pepper

♨ Preparation

  1. Prepare the Vegetables
    Wash the leeks thoroughly, especially between the layers, and cut the white and light green sections into approximately 1 cm thick rings. Peel and finely dice the carrot, parsley root or celeriac, and onion. Wash and finely chop the lovage or parsley and the fresh chives. Set the herbs aside for finishing.
  2. Sauté the Vegetables
    Heat the sunflower oil in a large saucepan over medium heat. Add the onion, carrot and parsley root or celeriac and sauté gently for approximately 5 minutes. Add the leek rings and cook for another 3–4 minutes until they begin to soften. Stir in the tomato paste and cook briefly to develop its flavour.
  3. Simmer the Soup
    Pour in the hot vegetable broth and season lightly with salt and freshly ground black pepper. Bring to a gentle boil, reduce the heat and cover the saucepan. Simmer for approximately 15–20 minutes until the leeks and root vegetables are tender.
  4. Add the Traditional Tanginess
    Stir in the freshly squeezed lemon juice, starting with 2 tablespoons. Taste and adjust gradually until the soup develops a pleasant, balanced acidity. Remove the saucepan briefly from the heat.
  5. Prepare the Creamy Thickener
    In a small bowl, whisk 3 tablespoons of vegan sour cream with the cornstarch and 2 tablespoons of cold water until completely smooth. Add a ladleful of hot soup and stir thoroughly to temper the mixture.
  6. Finish the Soup
    Slowly pour the tempered sour cream mixture back into the saucepan while stirring. Return to low heat and simmer gently for approximately 1 minute until the cornstarch has thickened the broth slightly. Remove from the heat, stir in the fresh lovage or parsley and optionally add a tiny pinch of Kala Namak. Adjust the seasoning if necessary.
  7. Garnish and Serve
    Divide the hot leek soup between two bowls, filling them almost to the rim. Transfer the remaining 2 tablespoons of vegan sour cream into a small piping bag and pipe a delicate decorative swirl into the centre of each bowl. Sprinkle generously with freshly chopped chives and serve immediately.

Food Story

There Is Always Room for Another Soup
Anyone who has followed my Via Veggie Vegan journey for a while probably knows that I have a serious weakness for soups. Give me a steaming bowl of something delicious during autumn or winter and I’m happy. But when the temperatures start rising, I simply switch to chilled soups for spring and summer. Apparently, my love affair with soup doesn’t have an off-season.

My Favourite Kind of Recipe Discovery
One of the things I absolutely love about researching dishes for my culinary journey around the world is discovering recipes that are already naturally vegan. No complicated substitutions, no wondering how to replace meat, eggs or dairy. Just vegetables, herbs, spices and generations of culinary tradition. Romanian fasting cuisine is a wonderful place to find that kind of inspiration. And every time I discover another plant-based dish, I celebrate it a little.

Romania, You Had Me at Leek Soup
This Ciorbă de Praz de Post turned out to be exactly my kind of comfort food: tender leeks, sweet carrots, aromatic herbs and a gently tangy broth. I gave mine a creamy finish with vegan sour cream and added a little piped swirl and fresh chives on top. Nothing overly complicated, just a beautiful bowl of comforting food. Because whether it’s hot, cold, creamy, chunky or spicy, I simply love eating. And soup will always have a very special place in my kitchen.

Good to Know

What Does "De Post" Mean in Romanian Cooking?
The Romanian expression "de post" refers to food prepared in accordance with religious fasting practices, especially those of the Romanian Orthodox Church. These dishes generally exclude meat, dairy products and eggs. Depending on the particular fasting day, fish and certain other foods may also be restricted. This tradition has contributed to a wide variety of plant-based Romanian recipes, including vegetable soups, bean stews, cabbage dishes and spreads.
Orthodox Fasting – More Than Just Giving Up Meat
Romanian Orthodox Christianity traditionally observes four major annual fasting periods: Great Lent before Easter, the Nativity Fast before Christmas, the Apostles' Fast and the Dormition Fast in August. Many observant believers also fast on Wednesdays and Fridays throughout much of the year, with exceptions. The exact dietary rules vary according to the religious calendar and individual pastoral guidance.
What About Alcohol During Orthodox Fasting?
Orthodox fasting is not simply about avoiding animal products. It is also associated with moderation, prayer, reflection and self-discipline. Traditional fasting rules restrict wine on certain days, while permitting it on others, often alongside oil. The Nativity Fast and Great Lent are two particularly significant fasting periods, but there is no universal rule requiring complete abstinence from every alcoholic beverage throughout both periods. My Via Veggie Vegan kitchen is alcohol-free all year round, regardless of the religious calendar.
Is Ciorbă de Praz de Post Naturally Vegan?
A fasting-style leek soup prepared exclusively with vegetables, vegetable broth, herbs and plant oil is naturally vegan. However, recipes vary, and some modern preparations may include dairy-based sour cream outside fasting periods. This version uses a plant-based alternative, keeping the entire dish vegan while adding a creamy finish.
Why Are Romanian Soups Often Sour?
One characteristic of Romanian ciorbă is its tanginess. Traditionally, this can come from borș, a fermented wheat-bran liquid, as well as lemon juice, vinegar or other souring ingredients. Borș in this context is not the same as beetroot borscht. For this recipe, fresh lemon juice provides a clean, bright acidity that complements the mild sweetness of the leeks and carrots.
Lovage – A Classic Romanian Soup Herb
Lovage, known as leuștean in Romanian, has a powerful herbal aroma reminiscent of celery. It is widely associated with Romanian soups and contributes a distinctive savoury freshness. Flat-leaf parsley makes a milder alternative, while fresh chives add a delicate onion flavour and a colourful finishing touch.
Why Temper Plant-Based Sour Cream?
Adding cold sour cream directly to a very hot soup can sometimes cause separation, depending on the product. Mixing it first with a little hot broth helps bring the temperatures closer together. Cornstarch provides additional stability and creates a gently thickened consistency without making the soup excessively heavy.
What About Kala Namak?
Kala Namak is a mineral salt with a characteristic sulphurous aroma reminiscent of cooked eggs. It is popular in vegan egg alternatives, but it is not a traditional or necessary ingredient in Romanian leek soup. A tiny pinch can add an unusual savoury note, although this soup tastes excellent without it.
