Pro Tips

• for Perfect Rogan Josh
• Don’t overcrowd the pan when browning the lamb. Searing in batches ensures a deep, flavorful crust which translates to a richer curry.
• Sauté the curry paste for a full minute before adding liquids. This ‘blooming’ process awakens the aromatic oils in the spices, maximizing their flavor.
• Stir in the sour cream or coconut milk off the heat or on the ‘keep warm’ setting to prevent it from curdling and ensure a smooth, creamy finish.
• This curry tastes even better the next day. The flavors meld and deepen overnight, making it a perfect make-ahead meal.

FAQ

Q: What cut of lamb is best for Rogan Josh

Q: How can I make this curry spicier
A: To increase the heat, add 1/2 to 1 teaspoon of cayenne pepper or extra chili powder when you add the Rogan Josh paste. The recipe notes mention you can easily dial up the warmth with a pinch of extra chili powder.

Q: Is this Lamb Rogan Josh recipe keto-friendly
A: Yes, with only 5.6g of net carbs per serving, this recipe is suitable for a ketogenic diet. Serve with cauli-rice or shirataki rice and use full-fat sour cream or creamed coconut milk to keep it low-carb.
