French Chicken in Vinegar Sauce with Caramelized Onions
Tender chicken thighs or breasts braised in a bright balsamic-wine reduction with sweet caramelized onions and fresh tarragon. This French-inspired dish balances acidity and subtle sweetness with a savory depth. The sauce reduces to coat the chicken, creating a glossy finish. Serve over rice or with crusty bread to soak up every drop. This lighter version uses cooking spray and chicken broth instead of cream or butter, keeping the focus on clean, classic flavors that work for weeknight dinners or casual entertaining.

Tips
Use thighs over breasts for juicier meat that stays tender during simmering; they have more fat and won't dry out.
Don't skip the caramelization step on onions, even though it adds just a few minutes. The browning develops deep flavor that elevates the whole dish.
Freshly minced tarragon provides brighter flavor than dried, but either works; add fresh at the end if using fresh for better color.
Good to Know
Refrigerate covered up to 3 days. Reheat gently on stovetop over medium-low heat or in covered oven at 120C until warmed through, about 10-15 minutes.
Prepare through step 4 (sauce mixed). Refrigerate sauce separately up to 1 day. Combine and braise when ready to cook.
Serve over rice, couscous, egg noodles, or with crusty bread. Pair with a dry white wine such as Sauvignon Blanc or Pinot Grigio.
Common Mistakes
Skip the caramelization step to avoid flat, one-dimensional flavor in the sauce.
Overcrowd the pan when searing chicken to avoid steaming instead of browning; work in batches if needed.
Cook without the cover too long to avoid dry chicken; braise covered for most of the time.
Use low-quality vinegar or skip it to avoid losing the bright acidity that defines this dish.

FAQ
Can I use chicken breasts instead of thighs?
Yes, use 4 boneless skinless breasts (6 ounces each). Check doneness at 12 minutes; breasts cook faster than thighs and can dry out if overcooked. Aim for 165F internal temperature.
What if I do not have fresh tarragon?
Dried tarragon works well; the recipe calls for 1 teaspoon dried as the conversion. You can also substitute with dried chervil or parsley, though the anise-like flavor of tarragon is distinctive to this dish.
Can I freeze leftovers and for how long?
Yes, cool completely and freeze in an airtight container for up to 2 months. Thaw overnight in the refrigerator. Reheat gently on the stovetop over medium-low heat, stirring occasionally, until warmed through.
