Comfort food at it's best! Plan ahead the chicken needs to soak in the buttermilk for 45 minutes. The complete recipe (gravy also) may be doubled to serve more than 3-4 people, just make certain that you use a large enough baking dish to accommodate all of the chicken, or use two baking pans, I just make this in two heavy 13x9-inch foil pans or use a large turkey roaster foil pan, I just discard the pans after...easy, no clean-up! You will love this chicken recipe! You can use canned mushrooms in place of fresh, but fresh it definatley better!
