Think of this as a lower-stress version of Chicken Cacciatore. Skin-on, bone in chicken thighs receive a flavor-boosting browning. They’re joined in the crockpot with the classic trio of aromatic vegetables: onion, celery, and garlic, with garlic, sautéed to soften. Moisten with broth, canned diced tomatoes, red wine, and balsamic, and let the slow cooker do its thing for 5 to 6 hours. Serve with creamy Polenta.
