The creamy buttermilk sauce bubbling gently around the chicken made the anticipation unbearable. When I finally sat down to eat, the crispy edges of the potatoes, the tender chicken, and the subtle smoky notes all worked together to melt away the day’s chaos. It was exactly the kind of meal that makes you want to cook again tomorrow.

One-Pot Buttermilk Chicken and Potatoes Casserole
- Total Time: 1 hour
- Yield: 4
Description
A comforting and easy one-pot casserole featuring tender chicken thighs and crispy golden potatoes simmered in a creamy buttermilk sauce, perfect for a hearty weeknight dinner.
Ingredients
6 bone-in, skin-on chicken thighs
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
2 tablespoons olive oil
1 pound baby Yukon gold potatoes, halved
1 medium yellow onion, thinly sliced
3 cloves garlic, minced
1 cup low-sodium chicken broth
1 cup buttermilk
1 teaspoon dried thyme
1 teaspoon dried rosemary
1/2 teaspoon smoked paprika
2 tablespoons unsalted butter
2 tablespoons all-purpose flour
1/4 cup grated Parmesan cheese
2 tablespoons chopped fresh parsley
Instructions
Preheat the oven to 375°F (190°C).
Season the chicken thighs evenly with kosher salt and black pepper on both sides.
Heat olive oil in a large oven-safe skillet or Dutch oven over medium-high heat.
Add the chicken thighs skin-side down and sear for 5-7 minutes until the skin is golden brown and crispy. Flip and cook for an additional 3 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, add the halved potatoes and sliced onion. Cook for 5 minutes, stirring occasionally, until the onions soften and the potatoes begin to brown.
Add the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the potatoes and onions, stirring to coat evenly. Cook for 1-2 minutes to eliminate the raw flour taste.
Slowly pour in the chicken broth and buttermilk while stirring constantly to create a creamy sauce.
Add the dried thyme, dried rosemary, and smoked paprika. Stir to combine.
Return the chicken thighs to the skillet, placing them on top of the potatoes and onions, skin-side up.
Dot the butter evenly over the top of the casserole.
Transfer the skillet to the preheated oven and bake uncovered for 30-35 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C) and the potatoes are tender.
Remove the skillet from the oven and sprinkle the grated Parmesan cheese over the casserole.
Return to the oven for 3-5 minutes until the cheese is melted and slightly golden.
Garnish with chopped fresh parsley before serving.

FAQ
Can I use other types of chicken? Bone-in, skin-on thighs are best for this recipe because they stay juicy and develop a crispy skin, but boneless thighs or breasts can work if you adjust cooking time accordingly.
What if I don’t have buttermilk? You can substitute with milk mixed with a little lemon juice or vinegar to mimic the tang.
Is it possible to make this dairy-free? Yes – swap the butter for a plant-based alternative and use coconut or almond milk with a bit of acid instead of buttermilk.
How do I reheat leftovers without drying out the chicken? Warm gently in the oven or microwave with a cover to keep moisture locked in.
Warm, simple, and satisfying—this casserole is an invitation to slow down and enjoy the moment. Give it a try and see how quickly it becomes a weeknight favorite.
