A Classic Dish With Soul
Some dishes stand the test of time. They carry tradition, culture, and flavour in every bite. Lamb Rogan Josh is one of those iconic dishes — and at Raj, we bring it to life in a way that feels both authentic and unforgettable.
Located in the heart of Slough, Raj is known for its passion for Indian food made the right way — with fresh ingredients, slow cooking, balanced spices, and genuine warmth. Among all our customer favourites, Lamb Rogan Josh holds a special place.
But what makes it so special? Let’s take you behind the scenes.
The Origins of Rogan Josh
Rogan Josh is a traditional dish from Kashmir, known for its deep red colour, tender lamb, and rich, spiced gravy. It was brought to India by the Mughals and over time, became a staple in Indian kitchens across the country — especially in the north.
The name itself comes from two words:
“Rogan” meaning oil or ghee
“Josh” meaning intense heat or passion
At Raj, we honour these roots by keeping the preparation close to its heritage, while also fine-tuning the dish to suit today’s taste buds. The result is something bold, comforting, and full of soul.
What Makes Raj’s Lamb Rogan Josh So Special?
We know a lot of restaurants serve this dish. But here’s what sets ours apart:
1. High-Quality Lamb, Always
We use lamb shoulder, a cut that’s perfect for slow cooking. It’s marbled with just the right amount of fat, making the meat ultra tender and juicy after hours of cooking. Every bite practically melts in your mouth — rich, soft, and satisfying.
2. Slow Cooking, No Shortcuts
We don’t rush our food. That’s the Raj promise.
Our Lamb Rogan Josh is cooked low and slow — letting the flavours develop naturally. The spices are gently toasted, the onions caramelised until golden, and the sauce simmered until thick and silky. It takes time, but that time creates depth.
3. Hand-Blended Spices
No store-bought mixes here.
We blend our own garam masala and other spices by hand to create the perfect flavour profile. Our blend includes:
Green cardamom
Cinnamon stick
Cloves
Ground cumin
Ground coriander
Turmeric
Kashmiri red chilli (for colour and mild heat)
Fennel powder
Paprika
Garlic and ginger paste
Each spice plays its part — no one overpowers the other. The result? A curry that’s full of warmth and harmony, not fire and shock.
4. Rich, Balanced Gravy
The sauce is the heart of any Rogan Josh. At Raj, we use:
Thick natural yoghurt
Ripe tomatoes
Caramelised onions
A spoon of ghee (clarified butter)
This base is simmered until it turns into a rich, velvety gravy that coats the lamb and clings to your naan or rice. The yoghurt adds creaminess without heaviness, and the tomatoes bring a gentle tang to balance the richness.
5. Flavour Without Fire
A lot of people assume Indian food has to be spicy. We don’t believe that.
Our Lamb Rogan Josh is about depth, not heat. We use Kashmiri chilli, which gives the dish a beautiful red colour and a warm glow — but not an overpowering burn. This makes the dish enjoyable for all spice levels — even kids love it!
6. Cooked With Care
There’s something you can’t fake in cooking — and that’s care.
Every Lamb Rogan Josh at Raj is made with attention, pride, and passion. You can taste it in the balance, the smooth texture, the comforting aroma that greets you as the dish arrives at your table.
What to Eat with Lamb Rogan Josh
One of the best things about this dish is how beautifully it pairs with other items. To truly enjoy it, we recommend the following combinations:
Basmati Rice
Simple, fragrant rice lets the curry shine. It absorbs the gravy and makes every bite comforting and complete.
Tandoori Naan
Our naan is soft, chewy, and baked fresh. Use it to scoop up the lamb and mop up the sauce — there’s nothing better.
Raita or Cucumber Salad
A cool, creamy raita balances out the richness of the curry and adds freshness to the plate. Try our mint raita or classic cucumber version.
Mango Lassi or Chutney
For contrast, a sip of chilled mango lassi or a spoon of sweet mango chutney gives you that sweet-savory balance that makes Indian food so exciting.
A Dish That Tells a Story
What makes Raj’s Lamb Rogan Josh so unforgettable is not just the taste — it’s the feeling.
From the way it smells to the way it warms your stomach and soul, this dish tells the story of real cooking. Of chefs who learned from family kitchens. Of spices toasted in ghee. Of food made not to impress — but to nourish and satisfy.
