Creamy Garlic Mushroom Chicken Potato Bake
There’s something incredibly comforting about a bubbling chicken and potato bake coming straight from the oven. This Creamy Garlic Mushroom Chicken & Potato Bake has everything you want in a cozy homemade meal: crispy-skinned chicken, tender potatoes, buttery mushrooms, and a rich Parmesan cream sauce scented with garlic and herbs.
The potatoes slowly soak up the creamy sauce as they bake, becoming soft and flavorful underneath the chicken. Meanwhile, the chicken stays juicy inside while the skin turns beautifully golden on top.
It’s hearty without feeling complicated, and most of the magic happens right in one baking dish. That makes it perfect for a relaxed family meal, a chilly evening, or any day when you’re craving something warm and satisfying.
And once the garlic, mushrooms, thyme, and rosemary start filling the kitchen with their aroma, waiting for it to finish baking might be the hardest part.
Ingredients
- 6 bone-in, skin-on chicken thighs
- 1 1/2 pounds (680 g) potatoes, thinly sliced
- 10 ounces (280 g) mushrooms, sliced
- 1 small onion, thinly sliced
- 4 cloves garlic, minced
- 2 tablespoons olive oil
- 2 tablespoons butter
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- Salt and black pepper, to taste
- 1 cup chicken broth
- 1 cup heavy cream
- 1/2 cup freshly grated Parmesan cheese
- 1 tablespoon all-purpose flour
- 2 tablespoons fresh parsley, chopped
Instructions
1. Prepare the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a large baking dish and set it aside.
2. Season the Chicken
Pat the chicken thighs dry with paper towels.
This little step helps the skin brown much better.
Season both sides with paprika, garlic powder, thyme, rosemary, salt, and freshly ground black pepper.
3. Sear Until Golden
Heat the olive oil in a large skillet over medium-high heat.
Place the chicken thighs skin-side down in the hot skillet.
Let them cook undisturbed for about 4–5 minutes, until the skin becomes deeply golden and crisp.
Flip and cook the other side for another 2 minutes.
Transfer the chicken to a plate. It doesn’t need to be fully cooked yet because it will finish in the oven.
4. Cook the Mushrooms and Onion
Reduce the heat to medium and add the butter to the same skillet.
Once melted, add the sliced mushrooms and onion.
Cook for 5–6 minutes, stirring occasionally, until the mushrooms have softened and developed some golden color.
They’ll also pick up all those flavorful browned bits left behind by the chicken.
5. Add the Garlic
Stir in the minced garlic.
Cook for about 30 seconds, just until fragrant.
You don’t want the garlic to brown too much—just enough to release that warm, savory aroma.
6. Make the Creamy Mushroom Sauce
Sprinkle the flour over the mushroom mixture and stir for about 1 minute.
Slowly pour in the chicken broth while stirring so the sauce stays smooth.
Add the heavy cream and Parmesan cheese.
Let everything simmer gently for 2–3 minutes, until the sauce begins to thicken slightly.
Taste and adjust the salt and pepper if needed.
7. Assemble the Bake
Arrange the thinly sliced potatoes evenly across the bottom of the prepared baking dish.
Pour most of the creamy mushroom sauce over the potatoes, making sure the sauce reaches between the slices.
Place the seared chicken thighs on top, skin-side up.
Spoon the remaining mushrooms and cream sauce around the chicken.
Try to keep the chicken skin mostly uncovered so it can stay crisp while baking.
8. Bake Until Tender
Cover the baking dish loosely with foil.
Bake for about 30 minutes.
Remove the foil and continue baking uncovered for another 20–25 minutes.
The potatoes should be fork-tender, the sauce should be bubbling, and the chicken should reach an internal temperature of 165°F (74°C).
9. Brown and Finish
For an extra golden finish, place the dish under the broiler for 2–3 minutes.
Keep a close eye on it so the chicken skin doesn’t burn.
Remove from the oven and let the bake rest for a few minutes.
Finish with a generous sprinkle of chopped fresh parsley.
Presentation
This dish is especially inviting served straight from the baking dish while the creamy sauce is still gently bubbling around the edges.
Place one chicken thigh on each plate and spoon plenty of tender potatoes, mushrooms, and creamy garlic sauce alongside it.
A sprinkle of fresh parsley adds a little color and freshness to the rich sauce.
For a complete meal, pair it with roasted green beans, steamed broccoli, asparagus, or a simple green salad.
Warm crusty bread is also perfect for soaking up any creamy mushroom sauce left on the plate.
