Few Indian dishes have travelled as far as Rogan Josh. What started as a traditional Kashmiri dish has become a favourite on menus across the world, including in the UK. But along the way, different versions have appeared, and not everyone agrees on what makes a proper Rogan Josh.
So, where did it all begin? What makes the Kashmiri version different from the British curry house favourite? And what does Gordon Ramsay have to do with the debate? Let’s explore its history, flavours and global journey.
What is rogan josh?
Rogan josh is a braised meat curry from Kashmir in northern India. The meat cooks slowly until it is tender and the sauce turns deep red. The red colour comes mainly from Kashmiri chillies, which add colour and flavour with only moderate heat.
The meat is usually lamb, mutton or goat, often cooked on the bone. The sauce is built on oil or fat, ground spices and, in many recipes, yoghurt. Rogan josh is usually served with steamed rice or flatbread.
The name is commonly explained as Persian. “Rogan” means oil or fat. “Josh” means heat, intensity or boiling. Together the words describe meat cooked in fat over strong heat.
Many diners know rogan josh as a standard curry house order. The dish has a much older place in Kashmiri cooking.
Where does rogan josh come from?
Rogan josh comes from Kashmir and is a staple of Kashmiri cuisine. According to Kashmir Life, it is one of the main dishes of the Wazwan, the Kashmiri multicourse meal. The Wazwan is a ceremonial feast served at weddings and other large gatherings.
Rogan josh sits alongside other Kashmiri meat dishes in that meal, such as gushtaba, which is a lamb meatball dish cooked in a yoghurt gravy.
Households across Kashmir cook rogan josh in different ways. Different communities make different choices about spices and aromatics. This means no single recipe is the only authentic one.
Restaurants outside Kashmir later adapted the dish for local tastes. That is why rogan josh looks and tastes different from one kitchen to the next.
What is traditional rogan josh made with?
Traditional rogan josh is made with bone-in lamb, mutton or goat, Kashmiri chillies, alkanet root, whole spices and slow cooking. Kashmir Life names alkanet root and Kashmiri chillies as the main sources of its colour and flavour. Alkanet root, known as ratan jot, is a natural dye that gives oil a red tint.
Other common ingredients include:
- Fennel and dried ginger powder, which give the sauce a warm, slightly sweet base
- Green cardamom, black cardamom, cloves and cinnamon
- Yoghurt, in many recipes
- Mustard oil or ghee as the cooking fat
- Asafoetida, in some home versions
Onion and garlic vary by recipe.
The method matters as much as the ingredient list. The meat simmers gently with the spices until the fat separates and the gravy turns glossy. Home recipes usually take around two hours.
Why is rogan josh famous around the world?
Rogan josh is famous because it travelled from Kashmiri kitchens to curry houses, cookbooks and television shows. It is a standard dish on UK Indian restaurant menus, from local takeaways to formal dining rooms. Travelmag notes that Veeraswamy in London lists Kashmiri rogan josh on its regional menu.
Television chefs helped spread the dish. Jamie Oliver gave it a full episode in the first series of Jamie’s 30 Minute Meals, titled “Rogan Josh Curry”. The episode served it with rice, carrot salad, poppadoms and flatbread.
The cooking series One World Kitchen also featured a chef making lamb rogan josh, butter chicken and chapatti from scratch.
The dish travels well because the method works with several meats. Cooks can use lamb, mutton or goat. Restaurants can also adjust the heat and richness for local guests.
How is UK rogan josh different from the Kashmiri original?
UK restaurant rogan josh often has a tomato-based sauce, while the Kashmiri original gets its colour from chillies and alkanet root. The two versions share a name and a general idea. They differ in method, base and garnish.
| Feature | Traditional Kashmiri rogan josh | Typical UK restaurant version |
| Colour source | Kashmiri chillies and ratan jot | Often tomato and chilli powder |
| Sauce base | Fat, ground spices and often yoghurt | Often an onion and tomato base |
| Meat | Lamb, mutton or goat on the bone | Often boneless lamb, sometimes chicken |
| Garnish | Usually plain | Often coriander, sometimes peppers |
| Heat | Mild to medium | Mild to medium, varies by kitchen |
A UK local newspaper review described a chicken rogan josh cooked with pimento, garlic, tomatoes, pepper and onions. That example shows how far restaurant versions can move from the Kashmiri recipe.
Neither version is wrong in its own setting. The UK version is an adaptation built for local tastes. The Kashmiri version is the home style that the name comes from.
Where can you eat rogan josh in London?
Rogan josh is on menus across London, from Mayfair dining rooms to Brick Lane curry houses. These places list it or are linked to it in published reviews and guides:
- Veeraswamy, near Regent Street: lists Kashmiri rogan josh on its regional menu. The Week describes it as the UK’s oldest surviving Indian restaurant.
- chennai spice : list rogan josh along with other curries
- Bibi, Mayfair: lists lamb rogan josh alongside butter chicken and Goan fish curry.
- Madhu’s, Southall: ranked first for rogan gosht in a small diner-recommendation comparison on one review site.
- Brick Lane: known as “Curry Lane”, with many curry houses serving traditional Indian dishes.
Menus change often, so check the current dishes before you book. Ask the kitchen whether it uses lamb, mutton or goat if the meat matters to you.
What goes well with rogan josh?
Steamed basmati rice is the classic partner for rogan josh. The rice soaks up the rich red gravy without competing with the spices. Flatbreads such as naan, roti and chapati also work well.
For a South Indian style meal, serve it with parotta, which is a flaky layered flatbread. Lemon rice gives a fresh, sharp contrast to the rich sauce.
Simple sides keep the plate balanced:
- Cucumber raita to cool the heat
- Kachumber salad of chopped onion, tomato and cucumber
- A plain dal for extra protein
- A light vegetable dish such as stir-fried green beans
Avoid heavy cream-based sides. They compete with the richness of the curry.
