The short answer
Thiou, also spelled tiou, is a comforting everyday Senegalese stew built on a deep tomato and onion base, simmered with meat or fish and vegetables until rich, and served over or alongside plain white rice. Onions and tomato paste are cooked down slowly into a thick, savoury sauce, then the protein and vegetables go in to simmer until tender. Common versions include thiou au poulet, made with chicken, and thiou a la viande, made with meat, and it belongs to the wider family of rice-based Senegalese classics. In the UK the ingredients to make it are sold by African food shops, which you can find near you on African Stores.

The smell of onions and tomato paste slowly cooking down is the smell of a Senegalese kitchen getting to work. Thiou is not a special-occasion showpiece; it is the honest, everyday stew that appears on the table when the family is hungry and dinner needs to be good. That patient, unhurried base, stirred until it turns deep and sweet, is the quiet heart of so much Senegalese home cooking.
For Senegalese and Gambian families in Britain, a pot of thiou over white rice is a plate of home. It is the reassurance of a familiar meal, the flavours of the Senegambian coast carried into a flat far from Dakar. To cook it here, cooking onions down without rushing, letting the tomato deepen, is to keep an everyday tradition alive, and to hand a bowl to a friend is to share a small, warming piece of Senegal.
What Thiou Actually Is
Thiou, sometimes written tiou, is a Senegalese stew defined by its base rather than any single protein. It begins with a generous quantity of onions and tomato paste cooked down slowly until they turn into a thick, deep, savoury sauce, and it is this patient reduction that gives the dish its rich colour and mellow, concentrated flavour. Into that base go meat or fish and a selection of vegetables, which simmer until everything is tender and the sauce has drawn in all the flavour.
Because the protein varies, thiou comes in named versions: thiou au poulet is made with chicken, and thiou a la viande is made with meat, while seafood versions use fish. It is a comforting, everyday dish rather than a festival centrepiece, the kind of reliable stew that a household cooks often. It sits naturally within the rice-based traditions of Senegalese food, and if you know the famous thieboudienne, you will recognise the same coastal love of a deep tomato base paired with rice.
How Thiou Is Made and Served
The making of thiou is really the making of its base. Onions are cooked down gently, then tomato paste is added and fried out, and the two are stirred together over patient heat until they collapse into a thick, rich, jammy sauce. Rushing this step is the one thing to avoid, because the depth of the finished stew comes from taking the time to let the onions and tomato mellow and sweeten before anything else joins the pot.
Once the base is ready, the meat or fish is added along with the vegetables, and water or stock brings it to a simmer that continues until the protein is cooked through and tender and the sauce is rich. Cooks season to taste, and the vegetables used depend on what is to hand. Thiou is served over or alongside plain white rice, which soaks up the sauce and balances its richness, making a complete and satisfying meal from a handful of everyday ingredients.
Why Thiou Matters in Senegal
Thiou is home cooking in the truest sense. It is not the dish trotted out for guests and celebrations, but the everyday stew that feeds a family well without fuss, and that quiet reliability is exactly why it matters. It shows the Senegalese instinct for building big flavour from simple, affordable ingredients through patience at the stove rather than a long list of components.
Senegalese cooking is largely shared with The Gambia and the wider West African coast, and thiou belongs to that Senegambian everyday tradition of rice served with a rich, tomato-based sauce. In its many versions, chicken one day, meat or fish another, it is endlessly adaptable to what a household has, which is part of what has kept it a staple of the daily table.
