Ingredients You’ll Need

Chicken and potatoes

• 2 pounds bone-in, skin-on chicken thighs or drumsticks – thighs stay juicy and crisp well
• 1.5 pounds Yukon Gold potatoes, cut into 1-inch chunks – thin-skinned potatoes hold shape and stay creamy
• 8 ounces cremini or baby bella mushrooms, sliced – white button mushrooms work too
• 3 tablespoons olive oil, divided
• 1.5 teaspoons kosher salt, plus more to taste
• 1 teaspoon freshly ground black pepper
• 2 teaspoons fresh thyme leaves – or 1 teaspoon dried
• 1 teaspoon fresh rosemary, finely chopped – or 1/2 teaspoon dried
• 3 cloves garlic, minced – 1 teaspoon garlic powder works in a pinch
• Zest of 1 lemon

Creamy white sauce

• 2 tablespoons unsalted butter
• 1 small shallot, finely minced – 1/4 cup minced onion works
• 2 tablespoons all-purpose flour – use a 2 teaspoon cornstarch slurry for gluten-free
• 1/2 cup dry white wine – chicken broth plus 1 teaspoon lemon juice works if you skip wine
• 1.25 cups low-sodium chicken broth – I like Better Than Bouillon or Kettle & Fire
• 3/4 cup heavy cream – half-and-half gives a lighter sauce
• 1 teaspoon Dijon mustard
• 1/4 cup grated Parmesan, optional for extra body
• 2 tablespoons chopped parsley

Pantry shortcuts and swaps

• Use rotisserie chicken if you need speed, then roast the potatoes and make the sauce on the stove.
• Stir in 1/2 teaspoon poultry seasoning if you do not have fresh herbs.
• Use canned sliced mushrooms in a hurry, but pat them dry so the sauce stays silky.

Equipment

• Large oven-safe skillet or braiser, 12 inches, or a Dutch oven
• Sheet pan if your skillet cannot fit everything
• Tongs and a wooden spoon
• Instant-read thermometer

How to Make Herb Roasted Chicken in Creamy White Sauce with Mushroom and Potatoes

Prep and preheat, 10 minutes

1. Heat the oven to 425 degrees F. Pat the chicken dry with paper towels so the skin crisps.
2. Toss potatoes with 1 tablespoon olive oil, half the salt and pepper, and half the herbs. Set aside.
3. Mix remaining salt, pepper, herbs, garlic, and lemon zest with 2 tablespoons olive oil. Rub all over the chicken.

Sear the chicken, 6 to 8 minutes

1. Heat the oven-safe skillet over medium-high. Lay chicken in, skin-side down, and sear until the skin turns deep golden, about 4 to 5 minutes.
2. Flip the chicken and cook 2 to 3 minutes more. Transfer chicken to a plate.

Roast with potatoes and mushrooms, 25 to 35 minutes

1. Scatter potatoes in the skillet. Nestle chicken on top, skin-side up.
2. Roast 15 minutes. Pull the skillet, add sliced mushrooms around the chicken, and stir the potatoes.
3. Return to the oven and roast until the chicken reaches 165 degrees F in the thickest part and potatoes turn tender, about 10 to 20 minutes more, depending on piece size.

Make the creamy white sauce, 8 to 10 minutes

1. Move chicken and potatoes to a warm plate and tent loosely with foil. Set the skillet over medium heat with whatever juices remain.
2. Melt butter in the skillet. Add shallot and cook until translucent, about 2 minutes.
3. Sprinkle in flour and stir for 1 minute to form a paste. Pour in wine and whisk until smooth, scraping up browned bits.
4. Stream in chicken broth and simmer until slightly thick, 2 to 3 minutes. Lower heat, whisk in cream, Dijon, and Parmesan. Simmer until the sauce coats the back of a spoon, about 2 minutes. Salt and pepper to taste.

Finish and serve, 3 to 5 minutes

1. Return chicken, potatoes, and mushrooms to the skillet and spoon sauce over everything. Let it bubble together 1 to 2 minutes.
2. Sprinkle with parsley. Serve hot with extra sauce on the side.

Tips & Tricks

• Dry the chicken well so the skin crisps instead of steaming.
• Salt the chicken 30 minutes ahead for deeper seasoning.
• Cut potatoes the same size so they roast evenly.
• Use high heat. The oven at 425 degrees F gives you crusty skin and golden edges.
• Keep the cream warm before adding so the sauce stays smooth.
• Skip wine? Add 1 teaspoon lemon juice or 1 teaspoon white wine vinegar to the broth.
• Go lighter by swapping half the cream with chicken broth, then reduce the sauce a minute longer.
• Want more mushrooms? Double them and sauté half with the shallot for extra browning.
• Check doneness with a thermometer, not the clock.
• Broil 1 to 2 minutes at the end if you want extra crispy skin. Watch closely.

What to Serve with Herb Roasted Chicken in Creamy White Sauce with Mushroom and Potatoes

A crisp salad with lemon vinaigrette balances the richness and makes the sauce pop. Roasted green beans or asparagus cook on the second rack and stay snappy. Warm crusty bread or buttered noodles soak up every last drop of creamy white sauce. If you pour wine, try Chardonnay or Pinot Noir, and if you skip alcohol, chilled sparkling water with a lemon wheel tastes bright and clean.

Make-Ahead and Storage

• Make-ahead: You can season the chicken up to 24 hours in advance and store it covered in the fridge. Toss potatoes in oil and herbs, then keep them in cold water and drain before roasting.
• Fridge: Store leftovers in an airtight container for 3 to 4 days. Keep the sauce separate if you can.
• Freezer: Chill completely, then freeze chicken and sauce up to 2 months. Potatoes can turn a bit grainy after freezing, so expect a softer texture.
• Reheat: Warm in a 325 degree F oven, covered, until hot, about 15 to 20 minutes. Reheat the sauce gently on the stove over low heat and thin with a splash of broth or cream. Finish under the broiler for 1 minute to re-crisp the skin.

Ingredients

  

• 4 pieces bone-in, skin-on chicken thighs
• 1 teaspoon salt
• 1/2 teaspoon freshly ground black pepper
• 1 teaspoon dried thyme
• 1 teaspoon dried rosemary, crushed
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 8 ounces cremini or button mushrooms, sliced
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 1 1/2 cups baby potatoes, halved
• 1 cup chicken broth
• 1 cup heavy cream
• 1 tablespoon all-purpose flour
• 1 teaspoon Dijon mustard
• 2 tablespoons fresh parsley, chopped

Instructions

 

1. Preheat the oven to 400°F (200°C). Pat the chicken thighs dry with paper towels and season all over with salt, pepper, dried thyme, and dried rosemary.
2. Heat the olive oil and 1 tablespoon of butter in a large oven-safe skillet over medium-high heat. Place the chicken thighs skin-side down and sear for 4–5 minutes per side until the skin is golden brown. Remove the chicken to a plate and set aside.
3. In the same skillet, reduce the heat to medium and add the remaining 1 tablespoon butter. Add the sliced mushrooms and cook for 4–5 minutes until they release their moisture and begin to brown.
4. Add the chopped onion and cook for 3–4 minutes until softened, then stir in the minced garlic and cook for 30 seconds until fragrant.
5. Sprinkle the flour over the vegetables and stir for 1 minute to coat. Gradually pour in the chicken broth while stirring, scraping up any browned bits from the bottom of the pan.
6. Add the heavy cream and Dijon mustard (if using), stirring until the sauce is smooth. Bring to a gentle simmer, then add the halved baby potatoes and toss to coat them in the sauce.
7. Return the seared chicken thighs to the skillet, skin-side up, nestling them into the sauce and potatoes. Spoon a little sauce over the chicken, leaving the skin exposed.
8. Transfer the skillet to the preheated oven and bake for 25–30 minutes, or until the chicken is cooked through (internal temperature reaches 165°F/74°C) and the potatoes are tender.
9. Remove from the oven and let rest for 5 minutes. Taste the sauce and adjust seasoning with additional salt and pepper if needed. Sprinkle with chopped fresh parsley before serving, if desired.
