Poulet au Vinaigre (French Chicken in Vinegar Sauce)

Poulet au vinaigre is a classic French chicken braise where vinegar is used not as a sharp finishing splash, but as the backbone of the sauce. Bone-in, skin-on thighs give the dish depth and stay tender as they simmer with softened shallots, chicken stock and tomato purée, which rounds out the acidity without making the sauce heavy. The result is glossy, savoury and distinctly tangy, with enough richness from the chicken juices and butter to keep it balanced. It is the kind of dinner that suits simple sides — potatoes, rice or good bread — because the shallot-studded sauce is very much part of the point.

Why this recipe works

  • Built-in depth: Browning the chicken first leaves savoury fond in the pan, which is lifted into the sauce when the vinegar and stock are added.
  • Sharp but balanced: White wine vinegar gives the dish its signature tang, while shallots, tomato purée and stock round out the acidity.
  • Classic sauce finish: Whisking in cold butter off the heat gives the sauce a smooth, glossy finish without making it heavy.

Ingredient notes

  • Use bone-in thighs: Bone-in, skin-on chicken thighs suit this style of braise because they stay juicy and add richness to the sauce.
  • Choose the vinegar carefully: White wine vinegar gives a clean, assertive tang; Champagne vinegar makes the sauce slightly softer and more rounded.

Common mistakes

  • Avoid a hard boil: Once the stock is added, keep the sauce at a gentle simmer so the chicken stays tender and the vinegar does not taste harsh.
  • Finish the butter off the heat: Whisk in the cold butter away from direct heat so it emulsifies smoothly rather than separating into the sauce.

Make-ahead tips

  • Good for making ahead: The chicken and sauce can be cooled and refrigerated, then reheated gently when needed.
  • Reheat gently: Warm in a saucepan over low heat until piping hot, adding a little chicken stock if the sauce has thickened too much.
  • Freezer-friendly: Freeze after cooking, then defrost overnight in the fridge before reheating gently.

Serving ideas

  • Serve with something absorbent: Mashed potatoes, steamed rice or crusty bread work well because the sauce is a key part of the dish.
  • Add a green side: Green beans, wilted greens or a simple salad give freshness alongside the rich, tangy sauce.

  1. Pat the chicken thighs dry and season all over with the fine sea salt and black pepper. Peel the shallots and slice them into thin rounds.
  2. Heat the olive oil in a Dutch oven over medium-high heat. Add the chicken thighs skin-side down and brown well for 6 to 8 minutes, then turn and brown the other side for 3 to 4 minutes. Transfer the chicken to a plate.
  3. Lower the heat to medium and add the shallots to the pot. Cook for 5 to 7 minutes, stirring, until softened and lightly golden.
  4. Stir in the tomato purée and cook for 1 minute to take off the raw edge. Pour in the white wine vinegar and let it bubble for 1 to 2 minutes, scraping up any browned bits.
  5. Add the chicken stock and bring to a gentle simmer. Return the chicken (and any juices) to the pot, nestling it into the sauce. Cover and simmer gently for 18 to 22 minutes, until the chicken is cooked through and tender.
  6. Uncover and simmer for 3 to 5 minutes to slightly thicken the sauce. Off the heat, whisk in the cold butter a little at a time until the sauce looks glossy. Serve the chicken hot with plenty of shallots and sauce spooned over.

Recipe notes

Tips

  • Keep the simmer gentle once the stock is added; a hard boil can make the chicken tighten and the sauce taste harsh.
  • Whisk in the butter off the heat so it emulsifies smoothly and stays glossy rather than splitting.

Substitutions

  • Replace White wine vinegar with Champagne vinegar for a slightly softer acidity.
  • Replace Shallot with Sweet onion for a rounder, less delicate flavour.

Storage

  • Refrigerate up to 3 days
  • Cool, then refrigerate in a sealed container for up to 3 days. Reheat gently in a saucepan over low heat until piping hot, adding a splash of chicken stock if the sauce has thickened; freeze for up to 2 months and defrost overnight in the fridge before reheating.
