01 - Pat the chicken thighs dry with paper towels. Season both sides generously with salt and pepper. Dredge each thigh lightly in flour, shaking off any excess.
02 - Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Working in batches to avoid crowding, sear the chicken thighs until golden brown on both sides, approximately 4 minutes per side. Transfer the browned chicken to a plate and set aside.
03 - In the same pot, add the diced onion, carrots, and celery. Sauté for 5 to 6 minutes until the vegetables have softened. Add the minced garlic and continue cooking for 1 minute until fragrant.
04 - Pour in the dry white wine, using a wooden spoon to scrape up any browned bits from the bottom of the pot. Allow the wine to reduce for 2 to 3 minutes.
05 - Add the diced tomatoes with their juices, chicken stock, dried thyme, and bay leaf. Stir to combine, then return the browned chicken thighs to the pot, nestling them into the liquid. Bring everything to a gentle simmer.
06 - Cover the pot with a tight-fitting lid and reduce the heat to low. Braise for 1 hour, stirring occasionally, until the chicken is fork-tender and nearly falling off the bone.
07 - Remove the lid for the final 15 minutes of cooking to allow the sauce to reduce and thicken to your desired consistency.
08 - Remove the pot from the heat. Discard the bay leaf. Stir in the lemon zest and chopped parsley. Taste and adjust the seasoning with additional salt and pepper as needed. Serve hot alongside creamy polenta, mashed potatoes, or crusty bread.
