Yassa Poulet
Also: Poulet Yassa, Yassa Chicken, Thiou Yassa
A Senegalese-Gambian dish of chicken marinated overnight in lemon juice, Dijon mustard, and aromatics, grilled to char, then slow-braised in a deeply caramelized onion-lemon-mustard sauce and served over rice.
Identity criteria
- 1Chicken must be marinated in the lemon-mustard-onion mixture for a minimum of several hours, ideally overnight
- 2Marinated chicken is grilled or broiled over high heat to develop char before any braising begins — this char is non-negotiable
- 3The onions must be cooked slowly until deeply golden-brown and jammy, not merely softened or translucent
- 4Both citrus acid (lemon) and mustard must be present in the sauce — removing either produces a different dish
- 5The dish is served over rice, traditionally thiéboudienne-style broken rice or long-grain rice
- 6Green olives are a canonical Senegalese addition that signals authenticity, though absent in some regional variants
Components
broken rice or long-grain white riceessentialYassa is always plated over rice; the sauce is meant to saturate it
chicken, bone-in pieces (legs and thighs preferred)essentialSkin-on pieces withstand the grill-then-braise double cook without drying out
yellow onions, large quantity (roughly equal weight to chicken)essentialVolume reduces dramatically during caramelization; under-onioning is the most common shortfall
garlic cloves, crushedessential
neutral vegetable oil (groundnut oil traditional)essential
fresh lemon juiceessentialProvides both marinade tenderizer and the signature bright-sour backbone of the sauce
the reserved marinade, used as braising liquidessentialThe marinade is not discarded — it becomes the sauce
Dijon mustardessentialEmulsifies the sauce and delivers characteristic sharpness; coarse-grain mustard is an acceptable regional variant
scotch bonnet or habanero pepper, whole or halvedoptionalAdded whole for moderate heat; pierced for more; omitted for mild
bay leavesoptional
black pepperessential
green olives, pittedoptionalCanonical in Senegalese versions; their brine acidity amplifies the sauce's brightness
Technique
- Overnight marinade
- Acid and mustard penetrate deeply only with time; a short marinade yields surface flavor and tough meat — the long soak is what makes the chicken fall-tender after braising
- High-heat grilling or broiling before braising
- Char on the skin creates bitter-smoky Maillard compounds that balance the acid-sweet sauce; skipping this step produces stewed chicken that is texturally and aromatically flat
- Deep caramelization of onions
- Onions must reach full golden-amber color (30–45 minutes) to develop sweetness that counterpoints the lemon; pulling them too early leaves the sauce thin and acrid
- Finishing the braise with reserved marinade
- Pouring the marinade back over the grilled chicken and caramelized onions integrates every layer — discarding the marinade loses the dish's depth entirely
Form & serving

- Family-style platter or individual bowl — chicken pieces resting on or beside rice, sauce ladled generously over both
- Temperature
- hot
- Portion
- one to two bone-in pieces per person with a substantial mound of rice
- Pairs with
- thiéboudienne broken rice · fried sweet plantains · bissap hibiscus drink · attaya (Senegalese mint tea)
Character
Flavour
Texture
Tender, fall-off-bone chicken in a glossy, jammy onion sauce that is thick but not starchy; rice below absorbs the sauce to a soft, saucy consistency
Eaten
Everyday family meal and celebratory dish across Senegal and the Gambia; a staple of Senegalese restaurants worldwide; commonly prepared for large gatherings and served communally from a shared platter

Variations & related
Regional variations
- Yassa Poisson · Casamance, Senegal
Fish (typically grouper or capitaine) replaces chicken; shorter marination and cook time; equally canonical
- Yassa Agneau · Senegal
Lamb variant for festive occasions; requires longer braise
- Gambian Yassa · Gambia
Typically spicier with more habanero; olives less common; sometimes includes carrots
- Yassa Ganaar (Casamance origin) · Casamance region, Senegal
The original Diola preparation; 'ganaar' is Diola for chicken; this name signals the dish's Casamance roots even in Dakar restaurants
- Grilled Yassa (no braise) · Street food, urban Senegal
Chicken grilled and served with the sauce on the side rather than braised in it; faster but loses the sauce-integrated depth

Substitutions
Dijon mustard → whole-grain mustardadmissible
Texture changes, flavor holds; acceptable
fresh lemon juice → lime juiceadmissible
Slightly more floral but functionally equivalent in the Gambian tradition
groundnut oil → sunflower or canola oiladmissible
Negligible flavor difference; safe
scotch bonnet → jalapeñoadmissible
Heat drops significantly; flavor profile shifts away from West African character
Dijon mustard → yellow American mustardinadmissible
Breaks authenticity — American mustard lacks the pungency and emulsifying power; sauce becomes thin and too sweet
fresh lemon juice → white wine vinegar onlyinadmissible
Loses the citrus aroma that is definitional; dish reads as a European onion sauce, not Yassa
grilling step → skipping directly to braisinginadmissible
Produces pallid braised chicken without char; texturally and aromatically wrong — the grill step is not optional
bone-in chicken → boneless chicken breastinadmissible
Overcooks during the braise; loses the collagen depth that enriches the sauce
Common mistakes
- Pulling the onions off heat while still pale or translucent — they must reach deep golden-amber or the sauce lacks sweetness and body
- Skipping or shortening the grill step, producing pale braised chicken with no char complexity
- Discarding the marinade instead of using it as the braising liquid, losing half the dish's flavor
- Marinating for under two hours — acid and mustard need overnight contact to penetrate the meat
- Using boneless, skinless chicken breast, which turns dry and chalky during the braise
- Under-lemoning: the sauce should taste bracingly citrus-forward before the sweetness of the onions rounds it
- Adding olives too early — they should go in for the last 10 minutes of braising only, or they turn bitter
Provenance
Yassa is widely attributed to the Diola people of the Casamance region of southern Senegal, where the name 'yassa ganaar' (chicken yassa) originates in the Diola language. The dish spread through Senegal and across the Senegambian region during the 20th century, becoming a pan-West African staple particularly associated with Senegalese national cuisine. Gambia, Guinea-Bissau, and the Senegalese diaspora worldwide all claim strong culinary traditions around it.
