Authentic Chicken Yassa with Caramelized Onions and Lemon
This authentic chicken yassa features bone-in chicken marinated in lemon and dijon, braised with a mountain of sweet caramelized onions and spicy scotch bonnet peppers.
If you are looking for a dish that perfectly balances bright acidity with deep, savory sweetness, chicken yassa is the ultimate Senegalese comfort food. This classic West African braise relies on a massive quantity of onions that melt down into a jammy sauce, cut through by a sharp, mustardy lemon marinade.
The secret to a great poulet yassa recipe lies in the patience of the marinade and the slow caramelization of the onions. By using bone-in chicken thighs, you ensure the meat stays succulent while it absorbs the heat of the scotch bonnet and the tang of the olives. It is a masterclass in building layers of flavor from humble pantry staples.
While this senegalese chicken yassa is traditionally served over white rice to soak up every drop of the onion gravy, it is equally spectacular alongside smoky jollof rice for a full West African feast. Don't be intimidated by the amount of onions—once they hit the heat, they transform into the silky, golden backbone of the dish.
Ingredients
The Marinade
- 4 lbs (1.8kg) bone-in, skin-on chicken thighs and drumsticks
- 1/2 cup (120ml) fresh lemon juice (about 4-5 large lemons)
- 3 tablespoons Dijon mustard
- 6 cloves garlic, minced
- 2 tablespoons peanut oil (or neutral oil)
- 1 tablespoon grated fresh ginger
- 1 tablespoon bouillon powder (chicken or vegetable)
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly cracked black pepper
The Braise
- 6 large yellow onions, thinly sliced (approx. 2.5 lbs)
- 1/4 cup (60ml) peanut oil
- 1-2 scotch bonnet or habanero peppers, pierced with a knife (keep whole for less heat)
- 1/2 cup (75g) pitted green olives (picholine or manzanilla)
- 2 bay leaves
- 1/2 cup (120ml) water or chicken stock
- Fresh parsley, chopped for garnish
Instructions
- 1
Whisk together the lemon juice, Dijon mustard, minced garlic, ginger, oil, bouillon, salt, and pepper in a large non-reactive bowl or gallon-sized zip-top bag.
- 2
Add the chicken pieces and sliced onions to the marinade, tossing thoroughly to ensure everything is coated. Refrigerate for at least 3 hours, though overnight is preferred for the best flavor penetration.
- 3
Remove the chicken from the marinade, scraping off any clinging onions; reserve the onions and all the liquid separately.
- 4
Heat the peanut oil in a large Dutch oven or heavy-bottomed skillet over medium-high heat. Sear the chicken in batches until the skin is deeply golden brown, about 5-6 minutes per side. Remove chicken and set aside.
- 5
Add the reserved marinated onions to the same pot. Cook over medium heat, stirring frequently, until they are soft and have turned a deep golden brown, about 15-20 minutes. If they stick, add a splash of water to deglaze the pan.
- 6
Pour in the remaining marinade liquid and the water or stock. Stir in the bay leaves, olives, and the whole scotch bonnet pepper.
- 7
Nestle the browned chicken pieces back into the bed of onions. Cover the pot and reduce heat to low.
- 8
Simmer for 30-40 minutes, or until the chicken is fall-apart tender and the sauce has thickened into a jam-like consistency.
- 9
Remove the bay leaves and the scotch bonnet pepper before serving. Taste and add an extra squeeze of lemon if you want more zing.
- 10
Garnish with fresh parsley and serve hot over steamed jasmine rice or jollof rice.

Tips
- → Do not skip the browning step. The fond left in the pan from searing the mustard-marinated chicken provides the base for the gravy's deep color.
- → If you want the heat without the burn, keep the scotch bonnet whole. If you want it truly spicy, mince half of the pepper into the marinade.
- → Use yellow or white onions rather than red; they have a higher sugar content which is essential for that signature sweet-and-sour yassa balance.
FAQ
Can I use chicken breast for chicken yassa?
You can, but it is not recommended. The long braising time required to melt the onions will often dry out lean white meat. Bone-in thighs provide the fat and collagen necessary for a rich sauce.
How do I make the onions more caramelized?
Patience is key. If your onions aren't browning after 15 minutes, increase the heat slightly and add a pinch of sugar or a tablespoon of water to help release the natural sugars from the pan.
Is chicken yassa supposed to be very sour?
It should have a prominent tang from the lemon and mustard, but it should be balanced by the sweetness of the cooked onions. If it's too tart, let the onions cook down longer next time.
