Senegalese yassa poulet is chicken marinated with lemon, mustard, garlic, and plenty of onions, then browned and gently simmered until tender. The bright, tangy sauce is usually served over rice; family and regional versions vary in their use of mustard, chile, and olives.
Ingredients
- 3 lb (1.36 kg) bone-in, skin-on chicken thighs, about 6 pieces
- 3 lb (1.36 kg) yellow onions, peeled and thinly sliced
- ¾ cup (180 ml) fresh lemon juice, from about 4 to 5 lemons
- 2 tbsp (30 g) Dijon mustard
- 5 garlic cloves (about 15 g), finely grated or minced
- ¼ cup (60 ml) neutral oil, such as canola, divided
- 2 tsp (10 g) fine salt
- 1 tsp (2 g) freshly ground black pepper
- 2 bay leaves (about 0.2 g)
- 1 Scotch bonnet pepper (about 10 g), left whole and pierced once with a knife; optional
- 1 cup (240 ml) low-sodium chicken stock or water
- ½ cup (75 g) pitted green olives, drained; optional
- 2 cups (370 g) long-grain white rice
- 3 cups (710 ml) water, for the rice
- ½ tsp (3 g) fine salt, for the rice
Instructions
- Make the marinade. In a large nonreactive bowl, mix the lemon juice, mustard, garlic, 1 teaspoon of the salt, the black pepper, and 2 tablespoons (30 ml) of the oil. Add the sliced onions and toss well so they are coated. Add the chicken and turn each piece to coat it, nestling the onions around and between the pieces. Cover and refrigerate for 2 hours. Keep the chicken chilled while it marinates; do not leave raw poultry on the counter.
- Separate the chicken and onions. Lift the chicken pieces out of the marinade and let excess liquid drip back into the bowl. Set the onion mixture and marinade aside. Pat the chicken skin dry with paper towels so it browns instead of steaming. Wash your hands and any tools or surfaces that touched raw chicken before using them for cooked food.
- Brown the chicken. Heat the remaining 2 tablespoons (30 ml) oil in a large, heavy Dutch oven or deep sauté pan over medium-high heat. Working in batches if needed, place the chicken skin-side down and brown for 6 to 7 minutes. Turn and brown the other side for about 4 minutes. Transfer the pieces to a plate. The chicken does not need to be fully cooked yet; it will finish in the sauce. If the pan has very dark, scorched bits, carefully wipe those out, leaving the flavorful browned fond.
- Soften the onions. Add the onion mixture to the same pan, along with the remaining 1 teaspoon salt. Cook over medium heat for about 15 minutes, stirring frequently and scraping up browned bits. The onions should soften and give off liquid, but they do not need to become deeply caramelized. If they begin sticking before they soften, lower the heat and stir in a tablespoon or two of water.
- Simmer the chicken. Pour in the stock or water and add the bay leaves and optional pierced Scotch bonnet. Stir, then arrange the chicken in the onions, skin-side up. Pour in any juices that collected on the plate. Bring the liquid to a gentle simmer, cover, and cook over low heat for 35 minutes. Keep the simmer gentle rather than letting the sauce boil hard; this helps the meat cook evenly and keeps the onions from catching on the bottom.
- Finish the sauce and check doneness. Uncover and simmer for about 8 minutes, turning the chicken once if needed to coat it in the sauce. Stir in the olives, if using, and simmer for 2 more minutes. Check the thickest part of each thigh with a food thermometer without touching the bone. Chicken must reach the USDA FSIS safe minimum internal temperature of 165°F (74°C). If a piece is not there yet, continue simmering and check again after a few minutes. Remove the bay leaves and whole chile before serving, or leave the chile on the side so diners can avoid it.
- Cook the rice while the chicken simmers. Rinse the rice in a fine-mesh strainer under cool water until the runoff is mostly clear, then drain. Combine it with 3 cups (710 ml) water and ½ teaspoon (3 g) salt in a saucepan. Bring to a boil, stir once, cover, and reduce the heat to low. Cook for 15 minutes, then turn off the heat and leave the covered pan undisturbed for 5 minutes. Fluff with a fork. Spoon the yassa and plenty of onion sauce over the rice.
Tips
- Give the onions time. Thin slices cook more evenly than thick wedges. A sharp knife or mandoline makes the large amount of onion easier to handle, but use a guard with a mandoline. Stir regularly during the first 15 minutes so the onions soften without burning.
- Adjust the lemon to taste. Lemon is central to yassa’s sharp, lively flavor, but lemons vary in acidity. If you prefer a softer sauce, begin with ½ cup (120 ml) juice and add a little more after cooking. Avoid replacing all of it with bottled lemon juice, which can taste flatter and sometimes harsher.
- Choose a manageable chile. Scotch bonnet is a traditional option in some versions and brings fruity heat. If it is hard to find, use a whole habanero, which has a similar kind of heat, or omit it for a mild dish. Keep the pepper whole for gentle flavor; cutting it releases more heat. Wash your hands after handling either pepper.
- Brown in batches. Crowding traps steam and prevents good browning. If your pot is not large enough to leave space between the thighs, brown them in two batches. Skinless thighs work too, though the sauce will have less richness and the meat will not develop crisp browned skin.
Serving Suggestions
Serve the chicken over a bed of plain long-grain rice, with generous spoonfuls of the softened onions and lemony cooking liquid. The rice absorbs the sauce and balances its acidity. If you want a more substantial spread, add a simple tomato and cucumber salad, shredded cabbage, or steamed greens. Keep side dishes lightly seasoned so they do not compete with the mustard, citrus, and onions.
For a communal-style meal, bring the pot to the table and let everyone take a piece of chicken, rice, and sauce. Offer the whole chile separately if you want guests to control the heat. A wedge of lemon is useful for anyone who likes an even brighter finish, while extra olives can be set out for diners who enjoy their salty, briny flavor.
Variations
Use chicken legs: Drumsticks or whole legs can replace the thighs. Keep the pieces similar in size and use a thermometer to check each one; larger legs may need additional simmering time. Chicken breasts are leaner and can dry out during a long braise, so use bone-in breasts and begin checking them earlier, removing each piece as soon as it reaches 165°F (74°C).
Make it without mustard: Mustard appears in many familiar yassa recipes, but it is not required in every family’s version. Leave it out for a sharper lemon-and-onion sauce, or use a mild whole-grain mustard for a more textured, less smooth flavor. Do not substitute an equal amount of prepared horseradish, which is much hotter and changes the character of the dish.
Add vegetables or change the protein: Stir in sliced carrots during the last 20 minutes of simmering if you want a sweeter, heartier sauce. Some cooks make yassa with fish instead of chicken; fish cooks much faster, so it should not be simmered for the full chicken cooking time. For a fish version, cook the onion sauce first, then add fish near the end and cook until the thickest part reaches 145°F (63°C).
Make it less rich: Remove the chicken skin before serving, or start with skinless thighs. The sauce will still be flavorful, though it will have less rendered fat. You can also reduce the oil used for browning to 1 tablespoon (15 ml) in a good nonstick or well-seasoned pan; add a splash of water if the onions need help loosening the browned bits.
Storage and Reheating
Refrigerate leftover chicken, sauce, and rice within 2 hours of cooking, in separate shallow airtight containers if possible. They keep for 3 to 4 days in the refrigerator. Keeping the rice separate makes it easier to portion and helps it retain a better texture, but it is also fine to store rice with some sauce spooned over it.
For longer storage, freeze the chicken and onion sauce in a freezer-safe container for up to 3 months for best quality. Rice can be frozen separately, though it may be a little softer after thawing. Thaw frozen portions in the refrigerator overnight rather than on the counter.
Reheat a serving in a covered saucepan over medium-low heat with a small splash of water or stock, stirring the sauce and turning the chicken occasionally. You can also microwave it in a covered, microwave-safe dish, stirring or rotating halfway through. Reheat leftovers to 165°F (74°C), checking the chicken and sauce with a food thermometer. Add a spoonful of water if the onions have thickened too much; avoid repeatedly cooling and reheating the same portion.
Frequently Asked Questions
Can I marinate the chicken overnight?
Yes. Keep it covered in the refrigerator and cook it within 24 hours. The two-hour marinade gives the lemon and mustard time to season the chicken without requiring an overnight wait. Because the marinade is acidic, very long marinating can affect the texture of the outer meat, so several days is not a good plan.
Can I make yassa ahead of time?
Yes. Cook the chicken and sauce a day ahead, cool and refrigerate them promptly, then reheat gently to 165°F (74°C). The onion sauce may taste more integrated after resting, and a little water or stock will loosen it as it warms. For the best rice texture, cook the rice on the day you plan to serve it.
Why is my yassa sauce too sour?
Lemon acidity varies, and a sauce can taste especially sharp before it is served with rice. Stir in a little water or stock and simmer briefly, then taste again. You can also serve extra rice or add more softened onions. A small pinch of sugar can round off an overly sharp batch, but use it sparingly so the sauce stays tangy rather than sweet.
Can I use boneless chicken thighs?
Yes. Boneless thighs cook faster than bone-in thighs, so start checking them before the 35-minute covered simmer is complete. Check the thickest piece with a thermometer and remove pieces individually when they reach 165°F (74°C). The sauce may need a few extra minutes to reduce after the chicken comes out.
Do the olives and Scotch bonnet have to be included?
No. Both are optional in this version. Olives add a salty, briny note, so taste the sauce before adding extra salt if you use them. The whole Scotch bonnet adds aromatic heat; leaving it out makes the dish milder without changing the lemon, mustard, and onion base.
