This oven-baked buttermilk chicken is the perfect combination of crispy, golden-brown skin and tender, juicy meat, all nestled alongside perfectly seasoned potatoes. It’s a one-pan dinner that feels like a warm hug on a plate—even better, it’s incredibly easy to make with pantry staples.

The buttermilk marinade works its magic, keeping the chicken moist while infusing it with a slightly tangy, savory flavor you won’t forget. Add in the aromatic punch of Herbes de Provence and a touch of ginger, and it’s no wonder my family requests this meal on repeat!

Why This Oven-Baked Buttermilk Chicken Is So Irresistible

Tender, Juicy Chicken: Buttermilk breaks down the proteins in chicken, resulting in succulent meat that stays moist even after baking.
Crispy, Perfectly Seasoned Skin: The combination of olive oil, soy sauce, and a quick oven blast creates golden, crispy chicken your taste buds will celebrate.
One-Pan Wonder: This recipe simplifies dinner by roasting everything—chicken and potatoes—in one dish for easy prep and cleanup.
Customizable: Add your favorite root veggies to the pan or tweak seasonings to match your flavor cravings.
Meal Prep-Friendly: The chicken marinates ahead of time, making it a great option for stress-free weeknight dinners or Sunday suppers.

Essential Ingredients for Perfect Oven-Baked Buttermilk Chicken

This recipe uses simple yet impactful ingredients that come together to create magic in your oven. Here are the stars:

Buttermilk: The key to tender chicken! Tangy and creamy, buttermilk transforms every bite into melt-in-your-mouth goodness. No buttermilk on hand? Mix 1 cup of milk with 1 tablespoon of lemon juice or vinegar for a quick substitute.
Herbes de Provence: This blend of aromatic herbs brings an earthy, floral note that elevates the chicken’s flavor. If you don’t have this, Italian seasoning makes a great replacement.
Potatoes: I love using new or baby potatoes for their creamy texture, but russet or Yukon gold potatoes cut into wedges work beautifully, too. Tossed in olive oil, they roast to golden, crispy perfection.
Soy Sauce: Adds a savoriness that deepens the flavor of the marinade. For a gluten-free option, swap in tamari or coconut aminos.

Ingredients for Oven-Baked Buttermilk Chicken

1 whole chicken cut into parts (thighs, wings, drumsticks, etc.), 1 kilogram (approx)
1/4 cup olive oil
1/4 cup red wine vinegar
1/2 cup soy sauce
1 cup buttermilk (or sour milk)
1 teaspoon Herbes de Provence seasoning
1 teaspoon ground ginger
8 barberries (optional)
1/2 teaspoon black pepper
1 teaspoon salt, plus more for potatoes
2 pounds potatoes (baby, new, or cut into wedges)

Step-by-Step Instructions for Oven-Baked Buttermilk Chicken

Preheat your oven to 360°F (180°C) and prepare a large roasting pan or rimmed baking sheet.
Pat the chicken pieces dry with paper towels to ensure crispy skin later.
Wash and prep the potatoes. If using small potatoes, leave them whole or cut them in half. For larger potatoes, cut into uniform wedges.
In a large mixing bowl, add the chicken pieces and drizzle with olive oil. Stir to coat evenly.
Pour in the red wine vinegar, soy sauce, and buttermilk. Sprinkle with Herbes de Provence, ground ginger, black pepper, and salt. Add the optional barberries for an extra tangy note.
Mix everything together, cover the bowl, and refrigerate for at least 2 hours (or overnight, if possible).
Arrange the marinated chicken pieces on the prepared baking sheet, leaving space around each piece for even cooking.
Scatter the potatoes around the chicken. Drizzle the potatoes with olive oil and season generously with salt and pepper.
Pour 1/4 cup of the leftover marinade over the chicken to lock in extra flavor.
Bake in the preheated oven for 45 minutes, basting the chicken with its juices halfway through cooking. You’re looking for the chicken to reach a safe internal temperature of 165°F and the potatoes to be fork-tender and golden.
Remove from the oven and let the chicken rest for 5 minutes before serving. Enjoy!

Pro Tips for Perfect Oven-Baked Buttermilk Chicken

Marinate for the Max Flavor: While 2 hours is sufficient, letting the chicken marinate overnight will infuse it with even more zest and tenderness.
Don’t Overpack the Pan: Give the chicken and potatoes enough room to roast and caramelize properly—crowding can cause steaming instead of browning.
Basting is Key: Don’t skip basting during cooking—it helps keep the chicken moist and enhances the flavor of the crispy skin.
Skip Barberries if Needed: Can’t find barberries? A touch of lemon zest makes a nice substitute.
Storing Leftovers: Refrigerate in an airtight container for up to 3 days. To reheat, bake in a 350°F oven until warmed through.

Delicious Oven-Baked Buttermilk Chicken Variations

Spicy Kick: Add 1 teaspoon of smoked paprika and a pinch of cayenne to the marinade for a bolder flavor.
Swap the Potatoes: Use sweet potatoes, carrots, or parsnips for a sweeter, earthy twist.
Dairy-Free: Replace buttermilk with coconut milk mixed with a splash of vinegar for a creamy, tangy alternative.

Oven-Baked Buttermilk Chicken FAQs

Can I use boneless chicken for this recipe?

Yes, boneless thighs or breasts work well, but reduce the baking time to prevent overcooking. Start checking for doneness at around 25 minutes.

What can I serve with this dish?

This dish pairs beautifully with a fresh green salad, roasted veggies, or a slice of crusty bread to soak up the juices.

Can I make this ahead of time?

Absolutely! Marinate the chicken the night before and store it in the fridge. The day-of, simply bake and serve. Leftovers also reheat wonderfully.

What’s the purpose of basting the chicken?

Basting helps lock in moisture and adds flavor to the crispy skin. You’ll be amazed by the difference it makes!

Can I use frozen chicken?

Defrost your chicken completely before marinating. Frozen chicken releases liquid as it thaws, which could dilute the marinade flavors.
