Wolof baseline braising technique, predates the peanut-driven mafé. The name «thiou» refers to the sauce method itself. Pre-colonial form used dried fish; modern versions diversified after 1960 with Italian-influenced tomato use rising during Sahel WWII food-aid programs.
Restaurant La Calebasse in Dakar's Plateau, run by Aïda Mbodj since 2003, serves thiou yapp daily as the cheap-lunch counterpart to thieb. Senegal imported $32M of canned tomato in 2022 — much used in thiou. Fresh tomato sauce is purist; canned is everyday.
Translucent red-orange sauce, looser than mafé, lemonier and brighter. The meat or fish stays distinct in the sauce, not coated heavily. Sometimes the rof paste appears stuffed into protein. A weekday dish, less of an event than thieb.
Onions cooked low 25 min, fresh tomato added 10 min, stock 30 min, protein last 20-40 min by type. No thickening agent — reduction is the only thickener. The 1:1 onion-to-tomato ratio is the marker of a proper thiou versus a lazy stew.
Variations
Thiou yapp (lamb), thiou poisson (fish, faster cook), thiou patat (sweet-potato vegetarian), and the Senegalese-French Marseille version that adds olives and saffron.

How it's made
4 steps · 13 min active + 1 hour 5 min waiting
- 110 min
Brown 500 g lamb in oil with 1 chopped onion + 4 garlic.
Watch outLet the lamb take real color before the onion goes limp — those browned bits are the whole flavor base, since nothing else thickens this stew.
- 245 min
Add 4 chopped tomatoes + 1 tbsp tomato paste + 500 ml water + bay; simmer 45 min.
Watch outKeep it at a lazy simmer, not a boil — you want the tomato and onion to melt down to a glossy base, reducing until the oil floats back up.
- 320 min
Add cubed potato or carrot; simmer 20 min.
Watch outAdd the potato only now — go in too early and it falls apart and clouds the sauce.
- 43 min
Serve over rice or couscous.
