Ingredients You Need
Chicken and Vegetables
- 4 to 6 bone-in, skin-on chicken thighs
- You can use drumsticks or a mix of thighs and drumsticks.
- I like air-chilled chicken because the skin crisps better.
- 1 ½ pounds baby potatoes, halved
- Use Yukon gold or red potatoes for a creamy texture.
- If you only have large potatoes, cut them into 1 ½ inch chunks.
- 8 ounces cremini or baby bella mushrooms, sliced
- White button mushrooms work, but cremini give deeper flavor.
- 1 medium yellow onion, thinly sliced
- 4 cloves garlic, minced
Herbs, Fats, and Seasoning
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon freshly ground black pepper
- 1 teaspoon dried Italian seasoning or herbes de Provence
- 1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
- 1 teaspoon dried rosemary or 1 tablespoon fresh rosemary, finely chopped
- ½ teaspoon smoked paprika or sweet paprika
You can use a pre-mixed poultry seasoning if you want a shortcut. Just skip extra thyme and rosemary so the flavor stays balanced.
Creamy White Sauce Base
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- Use a 1:1 gluten free flour blend if you avoid gluten.
- 1 ½ cups low sodium chicken broth
- I like Better Than Bouillon for a pantry-friendly option.
- 1 cup whole milk or half-and-half
- Use heavy cream for a richer sauce, or 2 percent milk for a lighter version.
- ¼ cup grated Parmesan cheese
- Use a wedge and grate it if you can; pre-shredded works in a pinch.
- ½ teaspoon Dijon mustard
- This does not make the sauce taste like mustard; it just adds depth.
- Juice of ½ lemon, plus extra wedges for serving
Optional Flavor Boosters
- ¼ teaspoon red pepper flakes for a little heat
- 2 tablespoons chopped fresh parsley for garnish
- Extra grated Parmesan for serving
Equipment List
- Large oven-safe skillet or braiser, 12 inch size
- A Dutch oven also works; just avoid a very thin pan that scorches easily.
- Tongs for turning chicken
- Wooden spoon or silicone spatula
- Small whisk for the white sauce
- Cutting board and sharp knife
- Measuring cups and spoons
Tips
- Pat the chicken very dry with paper towels so the skin crisps nicely.
- Season the chicken generously; bland chicken ruins a good sauce.
- Brown the chicken skin side down and leave it alone for a few minutes so it develops color.
- Slice mushrooms thick so they stay meaty and do not disappear into the sauce.
- Use medium heat when you sauté aromatics so the garlic does not burn.
- Warm the milk slightly before adding it to the pan to help the sauce stay smooth.
- Add the broth slowly while you whisk so the flour does not clump.
- Taste the sauce at the end and adjust salt, pepper, and lemon juice.
- Let the chicken rest a few minutes before serving so the juices settle.
- If the sauce thickens too much, thin it with a splash of warm broth or milk.
How to Make Herb Roasted Chicken in Creamy White Sauce
1: Season and brown the chicken
Pat the chicken thighs dry on all sides. Season them with salt, pepper, smoked paprika, thyme, and rosemary. Heat olive oil and butter in a large oven-safe skillet over medium high heat.
Place the chicken in the hot pan skin side down. Sear for 5 to 7 minutes until the skin turns deep golden and crisp. Flip the chicken and cook the second side for 3 to 4 minutes, then transfer the pieces to a plate.
2: Sauté mushrooms, onions, and garlic
Lower the heat to medium. Add the sliced onions and mushrooms to the same pan, and scrape up the browned bits from the bottom with a wooden spoon. Those bits carry a lot of flavor into the creamy white sauce.
Cook the onions and mushrooms for 6 to 8 minutes until they soften and take on some color. Add the minced garlic and Italian seasoning, then stir and cook for 1 minute until the garlic smells fragrant. Season lightly with salt and pepper.
3: Add potatoes and build the base
Add the halved baby potatoes to the pan and toss them with the mushrooms and onions. Coat them in the remaining fat and seasonings so they pick up flavor from the start. Cook for 3 to 4 minutes, stirring occasionally, so the edges start to turn golden.
Push the vegetables to the edges of the pan and create a small open space in the center. Add 2 tablespoons of butter to that space and let it melt. Sprinkle the flour over the melted butter and stir it into a paste.
4: Make the creamy white sauce
Whisk the flour and butter mixture for 1 to 2 minutes to cook out the raw flour taste. Slowly pour in the chicken broth while you whisk constantly so the mixture stays smooth. Add the milk or half-and-half in a slow stream and keep whisking.
Stir in the Dijon mustard and grated Parmesan cheese until the cheese melts and the sauce thickens slightly. Add the lemon juice and taste the sauce. Adjust salt and pepper until the creamy white sauce tastes rich and well seasoned.
5: Nestle the chicken and roast
Nestle the seared chicken thighs back into the pan, skin side up, on top of the potatoes and mushrooms. Spoon a little sauce over the meat, but keep most of the skin uncovered so it stays crisp. The sauce should come about halfway up the chicken.
Place the skillet in a preheated 400°F oven. Roast for 25 to 30 minutes until the chicken reaches 165°F in the thickest part and the potatoes feel tender when you pierce them with a fork. If you want extra crispy skin, switch the oven to broil for the last 2 to 3 minutes and watch closely.
6: Rest, garnish, and serve
Remove the pan from the oven and let the chicken rest for 5 minutes. The sauce will thicken slightly as it stands, which gives you that perfect spoon-coating texture. Sprinkle chopped fresh parsley and extra Parmesan over the top.
Taste a spoonful of sauce and add a squeeze of extra lemon if you want more brightness. Serve the herb roasted chicken with plenty of mushrooms, potatoes, and creamy white sauce in each bowl or plate. Enjoy the way the potatoes soak up every drop.
Different Ways to Try It
- Gluten free: Use a gluten free flour blend in the sauce and confirm your broth label.
- Lower carb: Swap potatoes for cauliflower florets or chunks of rutabaga or turnip.
- Lighter version: Use 2 percent milk and skip the extra Parmesan on top.
- Extra rich: Use half milk and half heavy cream for a thicker, more indulgent sauce.
- No mushrooms: Replace mushrooms with extra onions and some sliced zucchini.
- Dairy free: Use olive oil instead of butter, coconut milk or oat milk for the sauce, and skip the Parmesan or use a dairy free cheese.
- Herb twist: Try tarragon and parsley instead of rosemary and thyme for a fresher, lighter flavor.
- Spice lovers: Add red pepper flakes with the garlic or a pinch of cayenne to the sauce.
How to Serve
Serve Herb Roasted Chicken in Creamy White Sauce with Mushroom and Potatoes straight from the skillet at the table, family-style, so everyone can scoop extra sauce. Spoon a piece of chicken, a pile of potatoes, and plenty of mushrooms onto each plate, then ladle sauce over the top. Pair it with a simple green salad, steamed green beans, or roasted broccoli to balance the richness. Offer lemon wedges and extra Parmesan on the side so people can customize each serving.
Make-Ahead and Storage Success
You can season the chicken and cut the vegetables up to 24 hours ahead and store them in the fridge in airtight containers. If you want to cook the whole dish in advance, bake it fully, let it cool, and store it in the fridge for up to 3 days. Reheat portions on the stove over low heat with a splash of broth or milk until the sauce loosens and the chicken warms through. You can also freeze leftovers for up to 2 months, then thaw in the fridge overnight and reheat gently so the creamy white sauce stays smooth.
