In late summer on Tunisia’s Cap Bon peninsula, strings of red peppers hang from walls and rooftops to dry in the sun. In the kitchens of Nabeul, women pound them with garlic, caraway and coriander into a deep red, fiery paste. Every family’s jar tastes a little different, and every family says theirs is the best.
Harissa is Tunisia’s chilli paste: sun-dried red chillies ground with garlic, caraway, coriander, salt and olive oil. It goes into almost everything in Tunisian cooking, from couscous and stews to tuna sandwiches and the breakfast table, where it is served with olive oil and bread. In 2022 UNESCO added harissa to its list of Intangible Cultural Heritage, and Tunisia is the world’s largest exporter of the prepared paste.
This guide is for cooks buying a jar anywhere in the world and for visitors to Tunisia: how harissa is made, how Tunisians use it, how it differs across North Africa, how to choose a good jar, the harissa festival in Nabeul, and how to make it at home.
What Harissa Is Made Of
| Ingredient | Role |
|---|---|
| Dried red chillies | The base: traditionally sun-dried local peppers, including the mild Baklouti and hotter varieties |
| Garlic | Pungency and depth |
| Caraway (karwiya) | The signature Tunisian spice, giving an earthy, slightly aniseed note |
| Coriander seed | Citrusy warmth |
| Salt | Seasoning and preservation |
| Olive oil | Poured over the top to seal and preserve the paste |
Some households add cumin, lemon juice, tomato or a little fermented onion. The ratio of hot to mild peppers decides how fiery it is.
How Harissa Is Made in Tunisia
- Ripe red peppers are harvested in late summer, mostly on the Cap Bon peninsula around Nabeul.
- They are dried in the sun, then the stems and many of the seeds are removed.
- The dried peppers are soaked briefly and minced or pounded with garlic.
- Ground caraway, coriander and salt are mixed in.
- The paste is packed into jars and covered with olive oil, which preserves it for months.
Chillies came to Tunisia from the Americas, probably during the Spanish occupation of Tunis between 1535 and 1574. Over the following centuries the Cap Bon became the country’s pepper garden, and harissa its signature condiment.
How Tunisians Use Harissa
- At breakfast: a saucer of harissa drizzled with olive oil, eaten with bread and olives.
- In couscous: Tunisian couscous is famously red and spicy, with harissa in the sauce and more on the side.
- In sandwiches: the casse-croûte tunisien, a baguette with harissa, tuna, egg, olives and potato, and the fried fricassé roll.
- In shakshouka: eggs poached in a spicy pepper and tomato sauce.
- In lablabi: the chickpea soup poured over bread, finished with harissa, cumin and olive oil.
- In salads: slata mechouia, grilled peppers and tomatoes, often has harissa mixed in.
- As a marinade: rubbed on fish, chicken and lamb before grilling.
Harissa Across North Africa
Harissa is Tunisian in origin, but the whole region uses it:
- Algeria: added to soups, stews and couscous, and used as a rub for meat.
- Morocco: served as a condiment with tagines; Moroccans often prefer it milder.
- Libya: a similar pepper-and-garlic paste is part of everyday cooking.
- Abroad: chefs in the UK, Europe and North America use it in marinades, roasted vegetables, dips and dressings.
Harissa vs Hrouss, Rose Harissa and Other Pastes
| Paste | How it differs |
|---|---|
| Tunisian harissa | Dried red chillies, garlic, caraway and coriander; bold and earthy |
| Hrouss | A Tunisian paste of fermented onions with chilli and spices, salty and sour, made especially in the south |
| Rose harissa | Harissa with dried rose petals or rosewater, milder and fragrant; popular in British and European kitchens |
| Sriracha | A Thai-style chilli sauce with vinegar and sugar, thinner and sweeter |
| Chilli paste (sambal, gochujang) | Different chillies and flavourings; gochujang is fermented with rice |
How Hot Is Harissa?
It depends on the jar. Traditional Tunisian harissa ranges from medium to very hot, and many are hotter than sriracha. Some supermarket brands are mild and heavy on tomato. If you want real heat, look for Tunisian-made jars that list peppers as the first ingredient.
How to Choose a Good Jar
Tunisians on forums give the same advice again and again when people ask which harissa to buy abroad:
- Check the first ingredient. It should be peppers, not tomato paste or water.
- Look for Tunisian origin, often labelled “product of Tunisia”, especially from the Cap Bon or Nabeul.
- Short ingredient list: peppers, garlic, spices, salt and oil. Avoid long lists of thickeners and sugar.
- Tins and tubes are common for Tunisian harissa and are often more authentic than jars of “harissa sauce”.
- Artisan harissa from small producers is sold in delis and online and is closest to home-made.
Once opened, keep harissa in the fridge and cover it with a thin layer of olive oil to keep it fresh.
The Nabeul Harissa Festival
Nabeul, in the heart of the Cap Bon, holds an annual harissa festival, usually in October. Stalls sell harissa from family producers, women demonstrate traditional preparation with sun-dried peppers and spices, and the town celebrates harissa as a national symbol. If you visit Tunisia in autumn, it is the best place to taste and buy harissa straight from the makers.
From late summer, you will also see peppers drying on walls and terraces across the Cap Bon.
How to Make Harissa at Home
- Take about 100 g of dried red chillies (a mix of mild and hot), remove stems and most seeds, and soak them in hot water for 20–30 minutes.
- Toast 1 teaspoon each of caraway and coriander seeds in a dry pan, then grind them.
- Blend or pound the drained chillies with 4–6 garlic cloves, the spices and 1 teaspoon of salt to a thick paste.
- Stir in 2–3 tablespoons of olive oil.
- Pack into a clean jar, cover with olive oil and keep in the fridge for up to a month.
Wear gloves when handling hot chillies, and keep your hands away from your eyes.
Dietary and Halal Notes
Halal note: harissa is made from peppers, garlic, spices, salt and oil, so it is naturally halal, vegan and gluten-free. Tunisia is almost entirely Muslim, and harissa there is part of everyday halal cooking. Abroad, check jars for wine vinegar or unusual additives, which are rare; many Tunisian brands carry a halal logo. See our halal food travel guide.
