Ingredients
½ cup finely chopped tarragon (leaves and tender stems), plus 4 whole sprigs
2 garlic cloves, finely grated or minced
2 tablespoons extra-virgin olive oil, more for drizzling
1 ½ teaspoons kosher salt, more as needed
½ teaspoon ground black pepper, more as needed
3 pounds bone-in chicken thighs (skin on)
2 large onions, peeled and sliced (about 4 cups)
4 thyme sprigs
Sherry vinegar, to taste
Preparation
- Step 1
In a large bowl, stir together tarragon, garlic, oil, salt and pepper. Add chicken thighs and toss to coat. Cover with plastic wrap and chill for at least 6 hours, and up to overnight.
- Step 2
Heat oven to 425 degrees. Spread onions out on a rimmed baking sheet, drizzle with oil and sprinkle with salt and pepper and toss well. Clear spaces on the baking pan, then place chicken pieces in the cleared spaces so the onions surround the chicken. Strew thyme and tarragon sprigs over onions and chicken.
- Step 3
Roast, tossing the onions after 15 minutes, until chicken is cooked through and the onions tender, 25 to 35 minutes. If the chicken skin or onions are not as brown as you’d like, run pan under the broiler for 1 to 2 minutes at the end of cooking.
- Step 4
Place chicken on a platter. Drizzle onions with sherry vinegar and more salt and pepper if needed. Spoon onions around the chicken and serve.

I really wish food writers would stop writing "Marinate over night" as though you're going to cook it the next morning. A more precise way of writing would be to quantify the time in hours: 4, 6, 8,12 hours.
It's hotter on the top shelf and a good place to brown the chicken slowly without having to take the time to use the broiler later.
I made this with only 15 minutes marinating time. I used 3 onions because they reduce in size during cooking. I added some sherry during cooking because the chicken thighs I had on hand were skinless, after I'd tossed everything. I didn't put the additional herbs in during cooking, I used them for fresh chopped garnish on the serving platter. I use tarragon often and liked how it worked with the sherry flavors. Next time I'll add some thinly sliced potatoes.
Wedge, don’t slice, the onions. Slices will burn while the thighs brown. I liked red onions for this. Cut down on tarragon in the marinade, or else skip the sprigs on top. They char at that temperature anyway. I added small Yukon gold potatoes, unpeeled, to the pan after parboiling them. I sort of “deglazed” the pan with the sherry vinegar and some white wine, making more of a sauce than indicated here. Good.
Great recipe!
Boneless skinless thighs worked great. Such a tasty dish. I threw in some broccoli when I stirred the onions. Served with rice. Putting into regular rotation.
