I know it is easier to pick up a chicken at the grocery store, but this is really good and the gravy it makes is nice. Tomorrow I will take the grease off the top of the gravy and put the rest of the chicken in the gravy for leftovers.
Active time: 25 minutes
Total time: 2 hours
Preheat oven to 375°. Discard chicken neck and any included giblets. Pat chicken dry with paper towels and season generously with kosher salt and black pepper, including inside the cavity.
Place a 4-quart (or larger) Dutch oven or heavy oven-safe pot or pan over high heat. Add butter; when it melts and foams, add chicken. Brown chicken over high heat 10 minutes, using tongs to turn over. When chicken is evenly golden brown, turn it breast side down in pot and pour in milk. Bring to a simmer, then turn off heat.
Add to milk the lemon zest, garlic cloves, cinnamon, sage, and rosemary. Cover pot with a lid or foil and roast 45 minutes. Remove lid and roast until a thermometer inserted in the thickest part of the thigh registers 165°, 30 to 45 minutes more. Remove from oven and carve or shred chicken (it should pull off the bone easily). If needed, add salt to sauce to taste. Serve, spooning sauce from pan over meat.
