Marinate the chicken: Combine the buttermilk, ranch seasoning, and salt in a large bowl and whisk to dissolve. Add the chicken pieces and submerge in the buttermilk mixture. Cover with plastic wrap and refrigerate for 12 to 24 hours.
Prepare for roasting: Remove the chicken from the fridge. Preheat the oven to 425°F and place a rack in the center. Lightly grease a casserole dish, baking pan, or rimmed baking sheet large enough to accommodate the chicken in a single layer. Once the oven has preheated and the chicken isn’t quite so cold, use tongs to grasp a piece of chicken, letting excess buttermilk drip off before transferring to the baking dish. Place the chicken skin-side up. Repeat with the remaining chicken and sprinkle with salt. Discard the marinade.
Roast: Bake in the center of the oven, uncovered, until the breasts register at least 155°F in the thickest part (without touching the bone) and the dark meat registers at least 165°F, about 30 minutes. The temperature will continue to rise to safe temperature (at least 165°F) as the chicken rests. Let rest in the pan for 10 minutes. Transfer to a planner and top with a squeeze of lemon and chopped fresh herbs before serving, if using. Leftover ranch chicken can be stored in an airtight container in the refrigerator for up to 4 days. Love the recipe? Leave us stars and a review below!
