French chicken in vinegar sauce, or poulet au vinaigre, is a classic dish from the Lyon region, often called the capital of French gastronomy. It was popularized by chef Paul Bocuse. It’s known for its bold yet balanced sauce, where vinegar, wine, and pan juices come together into something surprisingly smooth and comforting.
This version stays true to the spirit of the dish while fitting comfortably into a Mediterranean Diet approach. The chicken is browned in olive oil, then gently baked in a tangy sauce that’s finished with just a small amount of butter for texture. The result is deeply flavorful, without feeling heavy, and well suited to a simple weeknight dinner or a relaxed weekend meal.
Why You’ll Love This French Chicken in Vinegar Sauce
Despite the name, this is not a sharp or aggressive vinegar dish. As the sauce cooks, the vinegar softens and blends with the wine, broth, and pan juices, creating a balanced flavor that’s closer to a gentle sweet-and-sour than anything harsh (see Escoffier’s Guide to Cooking with Vinegar).
The chicken is first browned to build depth, then baked slowly in the sauce so it stays tender while the flavors mellow and concentrate. A small amount of tomato paste adds roundness, and a final touch of butter gives the sauce its signature silky texture.
It’s a classic French preparation that feels comforting rather than heavy, with enough acidity to keep the dish lively.
Ingredients You’ll Need
This recipe uses simple, classic ingredients to build a balanced vinegar sauce. Find the complete recipe with measurements below.
- Chicken thighs – Bone-in, skin-on thighs stay tender during the longer bake and add depth to the sauce.
- Olive oil – Used to brown the chicken and sauté the aromatics.
- Shallot and garlic – Provide a mild sweetness and form the aromatic base of the sauce.
- White wine and chicken broth – Combined to create the cooking liquid. I use an uneven ratio because I keep small bottles of wine for cooking, but equal parts work just as well.
- Red wine vinegar – The defining ingredient of poulet au vinaigre, adding brightness.
- Tomato paste – Adds body and helps round out the acidity.
- Fresh rosemary and thyme – Used sparingly to add aroma.
- Butter – A small amount stirred in at the end to give the sauce a silky finish while keeping the dish in line with the Mediterranean Diet.
How to Make French Chicken in Vinegar Sauce
This is a high-level overview of the process. Full details and exact timings are in the recipe card below.
- Season and brown the chicken. Pat the chicken thighs dry, season with salt and pepper, and brown skin-side down in olive oil until golden. Flip briefly, then remove to a plate.
- Build the sauce base. Pour off excess fat, then sauté the shallot and garlic until softened. Deglaze the skillet with the wine, vinegar, and broth, scraping up the browned bits.
- Bake the chicken in the sauce. Return the chicken to the skillet, skin-side up, and bake uncovered until very tender. The chicken should sit in the sauce without being fully submerged.
- Finish the sauce. Remove the chicken, then reduce the sauce on the stovetop with tomato paste and fresh herbs. Stir in a small amount of butter off the heat for a silky finish.
- Serve. Spoon the finished sauce over the chicken and serve warm.

Keep the sides understated so the chicken and sauce remain the focus.
Recipe Tips and Variations
- About the cooking liquid
I use slightly uneven amounts of wine and broth because I keep small bottles of wine on hand for cooking. As long as you use about two cups of liquid total, the exact ratio isn’t critical. Using equal parts wine and broth works just as well. - Skillet choice
Avoid using a cast iron skillet for this recipe. The vinegar makes the sauce acidic, which can react with cast iron and affect both the skillet and the flavor. A stainless steel, oven-safe skillet works best. - Butter and the Mediterranean Diet
Finishing the sauce with a small amount of butter is traditional in this dish and gives it a silky texture. At one tablespoon for the whole recipe, it stays well within Mediterranean Diet guidelines. - Herb variations
Classic versions of poulet au vinaigre often use fresh tarragon. Because fresh tarragon can be hard to find where I live, I use rosemary and thyme instead. They work very well here and complement the vinegar sauce without overpowering it.
Advance Prep and Storage
Make-ahead
This dish can be made a day ahead. Store the chicken and sauce together, covered, in the refrigerator.
Reheating
Reheat in a 300°F oven, covered, until warmed through, about 20–30 minutes depending on the portion size. You can also reheat gently on the stovetop over low heat. If the sauce has separated slightly, stir it gently before serving to bring it back together.
Storage
Leftovers keep well in the refrigerator for up to 3 days.
Freezing
This dish can be frozen, but the texture of the sauce may change slightly. When reheating, warm it gently and stir the sauce to bring it back together.
Frequently Asked Questions
No. As the sauce cooks, the vinegar mellows and blends with the wine, broth, and pan juices. The finished dish has a balanced, gently tangy flavor rather than a sharp vinegar taste.
Red wine vinegar works best here. You could substitute white wine vinegar, but the flavor will be slightly sharper. Avoid balsamic vinegar, which will overpower the sauce.
Chicken thighs benefit from longer cooking and higher internal temperatures. Around 195°F allows the connective tissue to break down, resulting in more tender meat.
Yes. The chicken is cooked in olive oil, and only one tablespoon of butter is added at the end for the entire dish. This small amount provides the traditional silky texture while staying within Mediterranean Diet guidelines.
The wine adds depth, but if you prefer to avoid it, you can replace it with additional chicken broth. The sauce will still work, though it will be slightly less complex.

Equipment
Ingredients
- 6 chicken thighs, bone-in skin-on
- 1 tsp salt
- ¼ tsp black pepper
- 1 tbsp extra-virgin olive oil
- 1 large shallot minced (about ¼ cup)
- 2 cloves garlic minced
- 1¼ cups chicken broth
- ¾ cup dry white wine
- ⅓ cup red wine vinegar
- 1 tbsp tomato paste
- 1 tbsp unsalted butter
- ½ tbsp fresh rosemary chopped (or 1/2 tsp dry)
- ½ tbsp fresh thyme leaves (or 1/2 tsp dry)
Instructions
- Preheat the oven to 325°F with a rack set in the lower-middle position.
- Pat the chicken thighs dry with paper towels. Season both sides with salt and pepper.
- Heat the olive oil in a 12-inch oven-safe stainless steel skillet over medium-high heat. Add the chicken skin-side down and cook 7 minutes without moving it, until the skin is well browned. Flip and cook 3 minutes on the other side. Transfer the chicken to a plate.
- Carefully pour off all but about 2 tablespoons of fat from the skillet. Add the shallot and garlic and cook for about 1½ minutes, until softened but not browned.
- Add the wine, red wine vinegar, and chicken broth. Bring to a simmer, scraping up the browned bits from the bottom of the skillet.
- Return the chicken to the skillet, skin-side up. The chicken should not be fully submerged. Transfer the skillet to the oven and bake uncovered for 40–45 minutes, until the internal temperature reaches about 195°F.
- Remove the chicken to a serving dish. Return it to the turned-off oven, loosely covered, to keep warm while you finish the sauce.
- Place the skillet back on the stovetop over high heat. Stir in the tomato paste, rosemary, and thyme. Reduce the sauce to about 1¼ cups, about 10 minutes. Turn off the heat and stir in the butter until smooth.
- Taste and adjust seasoning with salt and pepper. Spoon the sauce over the chicken and serve.
Notes
- Skillet choice: Avoid cast iron. The acidic vinegar sauce can react with cast iron and affect both the pan and the flavor. A stainless steel skillet works best.
- Wine and broth: As long as you use about 2 cups of liquid total, the exact ratio of wine to broth isn’t critical. Equal parts work just fine.
- Butter: The sauce is finished with just 1 tablespoon of butter, which gives it a silky texture while staying within Mediterranean Diet guidelines.
- Reheating: Reheat covered in a 300°F oven for 20–30 minutes, or gently on the stovetop over low heat. Stir the sauce if it has separated slightly.
- Nutrition: Nutrition values are estimates and assume all rendered chicken fat is retained, even though most of it is discarded during cooking. Actual total fat and saturated fat will be lower, depending on how much fat is poured off.
I’ve always loved how French cooking can turn a few simple ingredients into something elevated. This poulet au vinaigre has become a favorite at our table and is perfect for guests.
When I first heard of this recipe, my first thought was “vinegar? really?”….WOW…what a lack of imagination I had! The reality is that this dish has a delicious flavor with some zip while not being overpowering. After having it first served fresh right out of the oven and finding it delicious, I was curious what it would be like after refrigerating the remaining chicken and microwaving a piece two days later….it was wonderful with the flavors fully saturated into the meat. This meal must be repeated!
