Grilled Senegalese Chicken with Yassa Marinade
Juicy chicken thighs swimming in a golden marinade of caramelized onions, bright mustard, and just enough chile heat to make you reach for seconds.
Bone-in chicken thighs bathe in a luscious marinade of jammy caramelized onions, bright Dijon mustard, and warming Scotch bonnet chiles before getting kissed by smoke and fire on the grill.
Ingredients
Yassa Marinade
- 3 largeyellow onions, thinly sliced
- 1/4 cupneutral oil
- 1/4 cupwhite wine vinegar
- 2 tablespoonsDijon mustard
- 1 wholeScotch bonnet chile, seeded and minced
- 4 clovesgarlic, minced
- 2 bay leavesbay leaves
- 1 teaspoonkosher salt
- 1/2 teaspoonblack pepper
Chicken
- 8 piecesbone-in chicken thighs, skin-on
- 1 teaspoonkosher salt
- 2 tablespoonslemon juice, fresh
For Serving
- 2 tablespoonsfresh parsley, chopped
- 1 wholelemon, cut into wedges
Method
1. Build the yassa base Warm the oil in your largest skillet over medium heat and add those sliced onions. Let them cook slowly, stirring now and then, until they turn the color of burnished gold and smell absolutely incredible. Pour in the vinegar—it'll sizzle and steam—then scrape up any caramelized bits stuck to the bottom. Whisk in the mustard, minced chile, garlic, bay leaves, salt, and pepper until everything comes together into a glossy, fragrant sauce.
Watch for: The onions should be deeply golden and jammy, with a sweet, concentrated aroma
Tip: This step is where all the magic happens—proper caramelization gives the sauce its soul
2. Marinate the chicken Pat those chicken thighs completely dry with paper towels, then season them all over with salt and bright lemon juice. Here's the smart move: scoop half of your beautiful yassa mixture into a container and stash it in the fridge for later. Toss the chicken with the remaining marinade in a big bowl, making sure every piece gets well coated. Cover and let it marinate in the refrigerator, flipping the pieces once if you remember.
Watch for: Each piece of chicken should be slicked with marinade and smell wonderfully aromatic
3. Grill to charred perfection Get your grill nice and hot—medium-high heat—and give those grates a good oiling. Lift the chicken from the marinade, letting the excess drip back into the bowl. Start skin-side down and resist the urge to move them around. You want that skin to get deeply golden and crispy before you even think about flipping. Once you get a good sear, flip and keep cooking until the thickest part of the thigh hits 165°F on your thermometer.
Watch for: The skin should be crackling and golden-brown, with clear juices running from the thickest part
Tip: If your grill starts flaring up, just slide the chicken to a cooler spot—no drama needed
4. Rest and finish Move the chicken to a serving platter and tent it loosely with foil—this little rest makes all the difference for juicy meat. While it's resting, warm up that reserved yassa sauce in a small pot until it's nice and glossy. Spoon the warm sauce generously over and around the chicken, then finish with a scatter of fresh parsley and those bright lemon wedges tucked alongside.
Watch for: The sauce should be warm and silky, ready to mingle with those incredible pan juices
Equipment
- large skillet
- gas or charcoal grill
- instant-read thermometer
- large mixing bowl
Make ahead
- The chicken is happy to marinate for up to a full day—just gets more flavorful. That yassa base actually improves after sitting in the fridge for a few days, so feel free to make it well ahead.
Storage
- Leftover chicken will keep in the fridge for three days, and that yassa sauce stores beautifully in its own container for even longer.
Reheat
- Warm leftover chicken gently in a 350°F oven for 10-12 minutes. Heat the sauce on the stovetop with a splash of water if it's gotten too thick.
Top tips
- That yassa base actually gets better after a day or two in the fridge—the flavors really have time to get acquainted
- If your grill tends to run hot, don't be shy about moving the chicken to a gentler spot once you get that beautiful char
- Any leftover yassa sauce is absolutely wonderful spooned over grilled vegetables or fish later in the week
Substitutions
- If Scotch bonnets aren't your thing, jalapeños will give you flavor without the serious heat
- Whole grain mustard works beautifully here if that's what you have on hand
- Bone-in chicken breasts work too, though they'll cook faster—keep an eye on them
Serve with
- Spoon this over a pile of fluffy jasmine rice or alongside some crusty bread for sopping up that incredible sauce
- Grilled plantains or roasted sweet potatoes make beautiful, sweet companions to all that tangy heat
- A simple salad of ripe tomatoes and thinly sliced onions dressed with lemon juice cuts through the richness perfectly

Why this recipe works
Editorial notes before you cook
There's something magical about the way yassa transforms on the grill—those caramelized onions get even deeper and smokier, while the mustard and chile create little pockets of flavor that char beautifully against the chicken skin. This is the kind of dish that fills your backyard with incredible aromas and brings everyone to the table asking what smells so good. The marinade pulls double duty as both flavor builder and finishing sauce, so you get layers of that tangy, aromatic heat in every bite.
The goal here is not just heat. It is contrast, pacing, and texture: enough richness to feel satisfying, enough brightness to keep the plate moving, and enough chile character that the spice actually tastes like something.

FAQ
The repeat questions
Can I make this without a grill?
Absolutely—a good cast-iron skillet will give you beautiful results, or you can roast everything in a 425°F oven and finish under the broiler for that charred look.
How spicy is this really?
With one seeded Scotch bonnet, you'll get a lovely warmth that builds as you eat, but the mustard and vinegar keep everything balanced—it's more complex than just hot.
What if I can't find Scotch bonnet chiles?
Habaneros are your best substitute, or use a couple of jalapeños if you want to keep things on the gentler side while still getting that authentic flavor.
