How to Make It
Place onions, mushrooms, carrots, and garlic in a 6-quart slow cooker.
Cook bacon in a large skillet over medium, stirring occasionally, until crispy and fat has rendered, 8 to 10 minutes. Transfer to slow cooker using a slotted spoon; reserve drippings in skillet. Increase heat to medium-high.
Season chicken with ½ teaspoon salt and the pepper. Cook chicken, skin side down, until skin is golden brown and crispy, 7 to 8 minutes. Transfer chicken to a plate; reserve drippings in skillet. Add flour and cook, whisking constantly, until slightly darkened, about 2 minutes. Add wine and cook, scraping up browned bits from bottom of skillet, until reduced by half, about 6 minutes. Pour into slow cooker.
Stir broth, thyme sprigs, and remaining ¾ teaspoon salt into slow cooker. Arrange chicken, skin side up, on top of mixture. Cover and cook on low until chicken is tender, about 5½ hours. Top with thyme leaves and serve with egg noodles.
