Chicken thighs marinated in lemon, mustard, and cayenne, then slow-cooked under a collapsing heap of caramelized onion that turns silky and sweet against the tang and heat. This is yassa as it should be — unapologetically seasoned, deeply aromatic, and made for passing around the table until the pot is clean.

Method
In a large bowl, combine chicken thighs with lemon juice and zest, mustard, cayenne, salt, and black pepper. Toss well to coat every piece. Cover and let rest at room temperature for 20 minutes.
While chicken marinates, slice all seven yellow onions into thin half-moons. In your Dutch oven over medium-low heat, warm the olive oil and add the onions. Stir with your wooden spoon.
Cook the onions slowly, stirring every few minutes, for 30 minutes until they turn deeply golden, soft, and sweet. Do not rush this — patience makes the yassa.
Cook the onions slowly, stirring every few minutes, for 45-60 minutes until they turn deeply golden, soft, and sweet. Do not rush this — patience makes the yassa.
Remove the onions to a plate and raise the heat to medium-high. Working in batches if needed, sear the marinated chicken thighs skin-side down for 4 minutes until golden, then flip and cook 2 more minutes. Set aside.
While the yassa braises, rinse the white rice under cold water until clear. In a separate pot, bring water and salt to a boil, add the rice, stir once, cover and simmer on very low heat for 18 minutes until fluffy and fully cooked.
Heap the cooked white rice into a wide communal bowl. Spoon the chicken yassa on top, letting the mountain of caramelized onion sauce flow down over the rice. Scatter fresh parsley generously over everything. Serve warm, and eat together.

Safety & Storage
Cooking Temperature
Chicken thighs must reach an internal temperature of 165°F (74°C) to ensure safe consumption. Use a meat thermometer to verify doneness before serving.
Cross Contamination
Raw chicken should be handled on a dedicated cutting board and with separate utensils. Wash all surfaces, hands, and tools thoroughly with hot soapy water after handling raw poultry.
Handling
Marinating raw chicken at room temperature for 20 minutes is acceptable but should not exceed 2 hours total. If marinating longer, refrigerate to prevent bacterial growth.
Storage
Leftover yassa should be cooled to room temperature within 2 hours, then refrigerated in airtight containers for up to 3-4 days. Reheat to 165°F (74°C) before consuming.
Allergen Warning
This dish contains mustard. Ensure all diners are aware of this allergen. Cross-contamination during preparation with other ingredients should be prevented.
Pro Tips
Technique
The onions are the soul of this yassa — do not rush them. Thirty minutes over medium-low heat, stirring every few minutes, until they melt into sweet golden ribbons. If they color too fast, add a splash of water and lower the heat. Patience makes the yassa, my grandmother always said.
Substitution
No whole mustard? Dijon works beautifully — just use one tablespoon and taste as you go. The lemon and cayenne stay essential though; they are the heartbeat of this dish and cannot be replaced.
From the chef
Yassa is a dish built entirely on patience with the onion. Seven yellow onions sliced thin, cooked thirty minutes low and slow until they collapse into a soft, golden sweetness — that is the foundation everything else rests on. The chicken thighs go in already bright from a lemon-mustard-cayenne marinade, then braise in that onion bed until the sauce turns glossy and coats the back of a spoon. A hard squeeze of fresh lemon over the top before serving. Heap it over white rice in one generous communal bowl and let everyone dig in together, because this yassa is absolutely made to be shared.
