Can I make Beef Rogan Josh instead of Lamb Rogan Josh?

You can substitute the lamb in this lamb curry recipe for beef and change the lamb stock to beef stock – just as nice! It’s a family favourite meal and so nice served with naan and poppadoms. Even the children really enjoy it and the flavours infuse wonderfully in the slow cooker. It’s also great for batch cooking and freezing for a tasty meal when you’re short of time.

Curries are amazing in the slow cooker as the longer you cook them for the more flavour they get plus, if you freeze them and use later they seem to get even more flavour still.

You can turn this into a beef rogan josh by switching the lamb for beef and the lamb stock for beef stock. You could even make slow cooker chicken rogan josh with chicken thighs and chicken stock – it’s such a simple and adaptable recipe. You can even add vegetables if you’re feeling adventurous.

This is our go-to curry for the whole family and even the children love it. The lamb rogan josh is a great recipe for a midweek dinner when you’re short of time – it can be put on in the morning and then done when you’re ready for dinner and the flavours just keep improving whilst it’s slow cooking.
