Can I use bone-in chicken instead of boneless breasts?
Yes, but increase oven time to 35–40 minutes and check that internal temperature reaches 165°F at the thickest part.
What if I don't have buttermilk?
Mix 1 cup regular milk with 1 tablespoon lemon juice or vinegar and let sit 5 minutes before using.
Can I make the gravy ahead of time?
Make it fresh after cooking the chicken to capture the pan drippings, but you can reheat stored gravy gently on the stovetop with a splash of milk.
How long does leftovers last?
Store chicken and gravy separately in airtight containers for up to 3 days. Reheat chicken at 350°F for 10–12 minutes until warmed through.
