Preheat the oven to 250°F. Add chopped bacon to an oven-proof skillet over medium-high heat. Brown completely, then transfer to a paper towel-lined plate. Drain all but 1 tablespoon of bacon drippings from the skillet.
Season chicken with salt and pepper on both sides. Brown evenly on all sides in the same skillet. Remove and set aside.
Add onion wedges to the skillet and sauté for a few minutes. Stir in minced garlic and reduce heat to medium.
Pour in chicken broth and red cooking wine.
Stir in tomato paste, bay leaf, thyme, and a pinch of salt and pepper. Bring the mixture to a light boil.
Return chicken and bacon to the skillet. Cover and bake for 55 minutes.
Remove the cover, add sliced mushrooms, and bake for another 15 minutes.
Plate the chicken and mushrooms, spoon sauce over, and enjoy!
Notes
