Italian Chickpea and Chestnut Soup – Zuppa di Ceci e Castagne

2 hours ago
7 min read

Zuppa di Ceci e Castagne is a rustic Italian soup built around two ingredients that have sustained rural communities for centuries: chickpeas and chestnuts.

Naturally vegan without requiring substitutions, this dish belongs to the old cucina povera tradition of central and southern Italy, where legumes, chestnuts, olive oil, herbs and preserved pantry ingredients created deeply satisfying meals during the colder months.

The combination is particularly effective because chickpeas provide body and a creamy texture while chestnuts contribute gentle sweetness and an earthy character. Garlic, rosemary and extra-virgin olive oil bring the two together, while tomato adds acidity and depth.

The finished soup should be thick but not heavy, with whole chickpeas, pieces of chestnut and a naturally creamy broth created partly by blending a small portion of the legumes.

History and Tradition

Chestnuts were once an essential source of carbohydrates throughout many mountainous areas of Italy.

Before wheat became inexpensive and widely available, chestnut trees were so important to rural communities that they were sometimes described as “bread trees.” Chestnuts could be eaten fresh, dried for winter, ground into flour or added directly to soups and stews.

Chickpeas have an equally long history in Italian cooking.

Their ability to be dried and stored made them especially valuable in communities where meat was expensive and seasonal availability determined what reached the table.

Combining legumes with chestnuts therefore made practical sense. Chickpeas provided protein and substance while chestnuts supplied carbohydrates and sweetness.

Variations of chickpea and chestnut soup developed across areas of Lazio, Abruzzo, Umbria and other parts of central Italy.

As with many traditional recipes, there is no single universal formula. Some versions contain tomato, others are almost white. Some are brothier, while others approach the consistency of a stew.

The version below focuses on balance: enough tomato to provide acidity, enough chestnut to create character, and enough chickpea purée to give the soup body without turning it into a cream.

Technical Explanation

The most important technical challenge is achieving a creamy soup without destroying the individual identity of the chickpeas and chestnuts.

Blending the entire soup would produce a uniform purée and remove the rustic character of the dish.

Instead, approximately one quarter of the chickpeas are blended with some cooking liquid and then returned to the pot.

This releases starch into the broth and creates natural viscosity.

Chestnuts should be added after the aromatic base has developed.

Cooked chestnuts are already soft. Adding them too early and stirring aggressively can cause them to break down completely.

Rosemary also requires restraint.

Its essential oils are strong, particularly when cooked for a long time. One small sprig is usually enough for a pot serving six people.

The soup should ultimately taste of chickpeas and chestnuts first, with rosemary functioning as an aromatic background rather than the dominant flavor.

Ingredients

Serves 6

3 cups cooked chickpeas, drained (about 500 g)
10 oz cooked and peeled chestnuts (285 g)
1 medium yellow onion, finely diced
1 medium carrot, finely diced
1 celery stalk, finely diced
2 garlic cloves, lightly crushed
1 cup crushed tomatoes (240 ml)
5 cups vegetable stock or water (1.2 liters)
1 small sprig fresh rosemary
1 bay leaf
1/4 cup extra-virgin olive oil (60 ml), plus more for finishing
1/2 tsp freshly ground black pepper
Kosher salt, to taste
1 pinch dried red chili flakes, optional
Italian parsley, finely chopped, for finishing

If using dried chickpeas, begin with approximately 1 1/2 cups (300 g) dried chickpeas and soak them overnight before cooking until tender.

Preparation

1. Prepare the Chickpeas

If using canned chickpeas, rinse them thoroughly under cold running water.

If using dried chickpeas, soak them overnight in plenty of water.

Drain, cover with fresh water and simmer gently until completely tender.

Do not aggressively salt the chickpeas at the beginning of cooking.

They should be creamy inside without falling apart.

2. Prepare the Aromatic Base

Heat the extra-virgin olive oil in a heavy-bottomed pot over medium-low heat.

Add the onion, carrot and celery.

Season with a small pinch of salt.

Cook gently for approximately 8–10 minutes.

The vegetables should soften and become lightly sweet without browning aggressively.

Add the garlic and cook for another minute.

If using chili flakes, add them now.

3. Add the Tomato

Add the crushed tomatoes to the aromatic vegetables.

Cook for approximately 5–7 minutes.

The tomato should lose its raw aroma and begin to concentrate.

This stage is important because tomato added directly to a large quantity of broth often remains thin and disconnected from the other flavors.

4. Add the Chickpeas

Add approximately three quarters of the cooked chickpeas to the pot.

Reserve the remaining quarter.

Pour in the vegetable stock or water.

Add the rosemary and bay leaf.

Bring the soup to a gentle simmer.

Cook for approximately 15 minutes.

5. Create the Natural Cream

Place the reserved chickpeas in a blender with approximately 1 cup of the hot cooking liquid.

Blend until smooth.

Return the chickpea cream to the pot.

Stir gently.

The broth should immediately become richer and more cohesive without becoming excessively thick.

6. Add the Chestnuts

Break approximately half of the chestnuts into large pieces and leave the remainder whole or halved.

Add them to the soup.

Simmer gently for another 10 minutes.

Avoid vigorous boiling.

The chestnuts should soften into the broth while still remaining recognizable.

7. Finish the Soup

Remove the rosemary sprig and bay leaf.

Taste and adjust the salt and black pepper.

If the soup is too thick, add a small amount of hot water or vegetable stock.

If it is too thin, simmer uncovered for several additional minutes.

Allow the soup to rest off the heat for approximately 10 minutes before serving.

Finish each bowl with extra-virgin olive oil and chopped parsley.

Professional Technique

The soffritto is the structural foundation of this recipe.

Do not rush it.

Onion, carrot and celery need gentle heat so that their natural sugars develop without burning.

A properly cooked soffritto produces depth that cannot be reproduced simply by increasing the quantity of herbs or salt later.

The second professional technique is controlling texture through partial blending.

Pureeing only part of the chickpeas creates a broth that feels naturally creamy while preserving the rustic structure of the soup.

This method works particularly well in vegan cooking because it creates richness without dairy, flour or artificial thickeners.

Finally, add the chestnuts late.

They are already cooked and delicate. Their purpose is not to dissolve entirely but to provide soft pieces that contrast with the chickpeas.

Chef Tips

Use good-quality cooked chestnuts with a naturally sweet aroma and no excessive dryness.

If using vacuum-packed chestnuts, inspect them before cooking and remove any hard fragments.

Use dried chickpeas whenever you have time. Their flavor and texture are usually superior to canned chickpeas.

Keep some chickpea cooking water. It contains starch and can improve the body of the soup.

Do not use too much rosemary.

Allow the finished soup to rest before serving. Legume soups become more harmonious after a short resting period.

Finish with excellent extra-virgin olive oil rather than cooking all of the oil for a long period. Fresh olive oil at the end contributes aroma, fruitiness and a slightly peppery finish.

For additional texture, serve the soup with toasted rustic Italian bread.

Common Mistakes

Blending the Entire Soup

This removes the contrast between chickpeas and chestnuts and transforms the dish into a purée.

Adding Too Much Tomato

Tomato should provide acidity and depth, not turn the dish into tomato soup.

Overusing Rosemary

Rosemary can easily overpower delicate chestnut flavor.

Boiling the Chestnuts Aggressively

Cooked chestnuts can disintegrate when subjected to vigorous boiling and excessive stirring.

Making the Soup Too Thick

The soup will continue to thicken as it rests. Leave it slightly looser than your desired final consistency while it is still on the stove.

Serving Immediately

A short resting period allows the starches to settle and the flavors to integrate.

Wine Pairing

The earthy sweetness of chestnuts and the creamy character of chickpeas work best with Italian wines that offer good acidity and moderate structure.

Montepulciano d’Abruzzo DOC

Montepulciano d’Abruzzo works particularly well when the soup is prepared with tomato. Its dark fruit, moderate tannins and savory character complement the earthy chickpeas and chestnuts without making the pairing excessively heavy.

Etna Bianco DOC

Etna Bianco provides a completely different approach. Its acidity and mineral character cut through the creamy texture of the chickpeas while remaining delicate enough for the chestnuts.

Grillo Sicilia DOC

Grillo offers citrus freshness, Mediterranean herbs and enough structure to stand beside the olive oil and legumes. It is an especially good choice when the soup is served as a first course.

Cerasuolo di Vittoria DOCG

Cerasuolo di Vittoria provides fresh red fruit and moderate tannin. Its brightness complements the tomato while its softer structure avoids overpowering the chestnuts.

How to Serve

Serve Zuppa di Ceci e Castagne warm rather than aggressively hot.

A wide soup bowl allows the aromas to develop more clearly.

Finish each serving with a drizzle of extra-virgin olive oil, freshly ground black pepper and chopped parsley.

Grilled or toasted country bread is the ideal accompaniment.

For a more substantial meal, rub the toasted bread lightly with garlic and place it directly at the bottom of the bowl before adding the soup.

The bread absorbs part of the broth and creates an even more rustic presentation.

Storage and Reheating

Store the soup in an airtight container in the refrigerator for up to 4 days.

As with many legume soups, the flavor generally improves after resting overnight.

The soup will thicken considerably in the refrigerator.

When reheating, add a small amount of water or vegetable stock and warm slowly over medium-low heat.

Avoid prolonged vigorous boiling because it can break down the chestnuts and chickpeas.

This soup can also be frozen for approximately 2 months.

Defrost slowly in the refrigerator before reheating.

Nutrition

Chickpeas provide plant-based protein, complex carbohydrates and dietary fiber.

Chestnuts differ nutritionally from most nuts because they contain considerably less fat and a higher proportion of carbohydrates.

Extra-virgin olive oil contributes primarily monounsaturated fats.

Because the recipe contains no dairy, eggs, meat or fish, it is naturally vegan.

Sodium will vary according to the vegetable stock and chickpeas used. When using canned chickpeas, rinsing them thoroughly can reduce some of the surface sodium.
