This slow-cooker lemongrass beef curry is a tried and tested favourite. Sarah PoundThis is one of those magical slow-cooker recipes that delivers unbelievable flavour with barely any effort. Everything simply gets thrown straight into the slow cooker – no frying off, no extra pans and absolutely no complicated prep. I’ve been making this recipe for more than 20 years, and it is still one of my all-time favourites. By the end of the day, the beef becomes melt-in-your-mouth tender, the sauce turns rich and deeply fragrant, and the whole house smells incredible.
