This one-pot creamy mushroom baked chicken is the kind of easy dinner I love making when I want something comforting without spending the whole evening in the kitchen. Tender chicken breasts bake right in a rich garlic cream sauce with plenty of savoury mushrooms, creating a flavourful meal that feels special but is still simple enough for a busy weeknight.
I like using mostly cremini mushrooms with a few shiitake mushrooms mixed in for deeper flavour. Everything cooks in one oven-safe pan, so the chicken stays juicy, the mushroom sauce becomes beautifully creamy and cleanup is easy. Serve it with rice, mashed potatoes or egg noodles to soak up every bit of that delicious sauce.
Short Description
This one-pot creamy mushroom baked chicken combines tender chicken breasts, sautéed mushrooms and a rich garlic cream sauce in one oven-safe pan. I like using mostly cremini mushrooms with a few shiitake mushrooms for extra savoury flavour. The chicken bakes right in the sauce, so it stays moist and picks up plenty of flavour.

Why It’s Good
This easy creamy mushroom chicken dinner tastes comforting and a little special, but it is still simple enough for a weeknight. Browning the chicken and mushrooms first adds much better flavour than placing everything straight into the oven. It takes a few extra minutes, but it is worth it.
The creamy sauce is also excellent with rice because it soaks into every bite. And since everything cooks in one pan, cleanup is fairly easy. Always a bonus.
Â
When to Serve It
Serve this baked chicken with creamy mushroom sauce for a cosy family dinner, a relaxed Sunday meal or when guests are coming and you want something dependable. It works especially well during fall and winter, although it is easy enough to make any time of year.
Add rice, mashed potatoes or egg noodles and a simple green vegetable for a complete dinner. The sauce is generous, so make sure you serve it with something that can soak it up.
Tips and Tricks
Use evenly sized chicken breasts. Thick chicken breasts take much longer to bake and can cook unevenly. Pound them slightly or slice very large breasts in half so this creamy mushroom baked chicken stays tender and juicy.
Brown the chicken first. It only takes a few minutes, but it adds much more flavour and gives the chicken that golden colour. The browned bits left in the pan also help flavour the creamy mushroom sauce.
Do not crowd the mushrooms. Give the mushrooms a little time to brown before adding the garlic and cream. If the pan is crowded, they release water and steam instead. I usually leave them alone for a minute or two before stirring.
Use cremini mushrooms for the best all-around result. They have a deeper flavour than white button mushrooms but are still mild. A few sliced shiitake mushrooms can be added for extra savoury flavour. Remove the tough shiitake stems first.
Add the garlic near the end of sautéing. Garlic can burn quickly and become bitter. Let the mushrooms brown first, then add the garlic for the final 30–60 seconds.
Pour the broth in gradually. Stir as you add it so the flour blends smoothly into the sauce. This helps prevent little flour lumps in your garlic cream sauce.
The sauce will thicken in the oven. It may look slightly thin before baking, and that is okay. Avoid reducing it too much on the stovetop or it could become overly thick once the chicken is cooked.
Check the chicken early. Baking time depends on the thickness of the breasts. The chicken is ready when the thickest part reaches 74°C (165°F). Overcooking is the main reason baked chicken becomes dry.
Let it rest for five minutes. This gives the juices time to settle and allows the creamy mushroom sauce to thicken slightly. Then spoon plenty of mushrooms and sauce over the chicken.
Serve it with something that catches the sauce. Rice, mashed potatoes and egg noodles all work well with this one-pan creamy mushroom chicken dinner. There is usually plenty of sauce, and you will not want to waste it.
Variations
Use chicken thighs instead. Boneless, skinless chicken thighs work very well in this creamy mushroom chicken recipe because they stay juicy and have plenty of flavour. They may need a few extra minutes in the oven, depending on their size.
Make it with only cremini mushrooms. Cremini mushrooms are easy to find and give the sauce a deeper flavour than white button mushrooms. They are my first choice when I want a simple, dependable baked chicken with mushroom sauce.
Add shiitake mushrooms. Replace about one-third of the cremini mushrooms with sliced shiitake mushrooms for a richer, more savoury taste. Remove the tough stems first. A little shiitake goes a long way.
Try a mixed mushroom version. Cremini, shiitake and oyster mushrooms create a more interesting texture and make this one-pot creamy mushroom chicken feel a bit more special. Just keep the total amount of mushrooms about the same.
Add spinach. Stir 2 cups of baby spinach into the sauce just before returning the chicken to the pan. It wilts quickly and adds colour without making the recipe complicated.
Add sun-dried tomatoes. A small handful of chopped sun-dried tomatoes gives the creamy sauce a slightly tangy, savoury flavour. Use the oil-packed kind, but drain them well first.
Make it dairy-free. Replace the butter with olive oil and use an unsweetened dairy-free cooking cream. Check that it is suitable for heating, since some dairy-free milks can separate in the oven.
Use half-and-half for a lighter sauce. The sauce will not be quite as rich, but it still works. Keep the heat gentle and avoid boiling it hard so the sauce stays smooth.
Add Parmesan cheese. Stir â…“ cup finely grated Parmesan into the sauce before adding the chicken back to the pan. It makes the garlic mushroom cream sauce richer and slightly thicker.
Give it a little heat. Add ¼ teaspoon crushed red pepper flakes with the garlic. It does not make the dish very spicy, but it gives the creamy sauce a nice little lift.
Change the herbs. Thyme is a natural match for mushrooms, but rosemary, tarragon or Italian seasoning also work. Use dried herbs sparingly. They can become strong while the chicken bakes.
Turn it into a complete vegetable dinner. Add small broccoli florets, green beans or asparagus during the last 10–15 minutes of baking. Keep the pieces fairly small so they cook through without overcooking the chicken.
Storage Tips
Refrigerate leftovers promptly. Let the creamy mushroom baked chicken cool slightly, then transfer it to an airtight container within two hours. Store the chicken and mushroom sauce together so the meat stays moist.
Keep it refrigerated for up to 3 days. The creamy sauce may thicken as it chills. That is normal. It usually loosens again once gently reheated.
Store the rice separately. If you are serving this one-pot mushroom chicken with rice, keep the rice in its own container. This prevents it from soaking up all the sauce and becoming too soft.
Reheat gently on the stovetop. Place the chicken and sauce in a covered skillet over low heat. Add a small splash of chicken broth, cream or milk if the sauce seems too thick. Turn the chicken occasionally until heated through.
Use the microwave for individual portions. Cover the dish loosely and heat at reduced power in short intervals. Full power can make the chicken tough and may cause the cream sauce to separate.
Avoid overcooking it during reheating. The chicken is already cooked, so it only needs to become hot. Gentle heat makes a real difference here.
Freezing is possible, but the sauce may change. Cream-based sauces can become slightly grainy after freezing and thawing. For the best texture, I prefer enjoying this creamy garlic mushroom chicken fresh or refrigerated.
To freeze, use an airtight container. Freeze the chicken with its mushroom sauce for up to 2 months. Thaw it overnight in the refrigerator, then reheat slowly while stirring the sauce.
Do not leave leftovers at room temperature for long. Discard any creamy chicken dish that has been sitting out for more than two hours.
One-Pot Creamy Mushroom Baked Chicken
Equipment
- Large oven-safe skillet or shallow Dutch oven
- Cutting board
- Sharp kitchen knife
- Measuring cups and spoons
- Wooden spoon or silicone spatula
- Tongs
- Small whisk
- Instant-read meat thermometer
- Plate for holding the browned chicken
Ingredients
- 4 chicken breasts boneless, skinless , about 170–200 g each
- ¾ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- 2 tablespoons olive oil
- 340 g mushrooms sliced - cremini mushrooms or shiitake mushrooms, stems removed and caps sliced
- 1 shallot small finely chopped or ½ small onion
- 3 garlic cloves minced
- 1 tablespoon butter
- 1 tablespoon all-purpose flour
- 1 cup chicken broth
- ¾ cup whipping cream
- 1 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- ½ teaspoon Worcestershire sauce
- ¼ teaspoon salt or to taste
- 2 tablespoons chopped fresh parsley
Instructions
Prepare the chicken.
- Preheat the oven to 190°C (375°F). Pat the chicken dry, then season both sides with the salt, pepper, garlic powder and paprika.
Brown the chicken.
- Heat the olive oil in a large oven-safe skillet or shallow Dutch oven over medium-high heat. Brown the chicken for about 2 minutes per side. It does not need to be cooked through. Transfer it to a plate.
Cook the mushrooms.
- Add the mushrooms to the same pan and cook for 4–5 minutes, stirring occasionally, until lightly browned. Add the shallot, garlic and butter. Cook for another minute.
Make the creamy sauce.
- Sprinkle the flour over the mushrooms and stir for 30 seconds. Gradually pour in the chicken broth while stirring. Add the cream, Dijon mustard, thyme and Worcestershire sauce. Simmer for 2–3 minutes, until the sauce begins to thicken. Taste and add the remaining salt as needed.
Bake the chicken.
- Return the chicken and any juices to the pan, spooning some mushrooms and sauce over each breast. Bake uncovered for 18–25 minutes, depending on the thickness of the chicken, until the centre reaches 74°C (165°F).
Finish and serve.
- Let the chicken rest in the sauce for 5 minutes. Scatter the parsley over the top and spoon the mushrooms and creamy sauce over each serving.
Serving suggestion
- Serve the creamy mushroom chicken over hot rice, mashed potatoes or buttered egg noodles, with plenty of sauce spooned over the top.
Notes
- Cremini mushrooms work best for this creamy mushroom baked chicken because they have a deeper flavour than white button mushrooms and hold their shape well in the sauce.
- For a richer mushroom flavour, replace about one-third of the cremini mushrooms with sliced shiitake mushrooms. Remove the tough stems before slicing.
- Choose chicken breasts that are fairly even in thickness. Very large chicken breasts can be sliced horizontally into thinner pieces so they cook more evenly and stay juicy.
- Browning the chicken before baking gives this one-pot chicken dinner better colour and flavour. It also leaves tasty browned bits in the pan that help flavour the creamy garlic mushroom sauce.
- Let the mushrooms cook for a few minutes before stirring too often. This helps them brown instead of becoming soft and watery.
- The sauce may look slightly thin before the pan goes into the oven. That is fine. It will thicken as the oven-baked chicken breasts finish cooking.
- Baking time can vary depending on the thickness of the chicken. Use an instant-read thermometer and cook until the centre reaches 74°C (165°F).
- Let the chicken rest in the sauce for about 5 minutes before serving. The sauce thickens a little more, and the chicken stays noticeably juicier.
- Serve this creamy mushroom chicken with rice, mashed potatoes or egg noodles. All three are good for soaking up the garlic mushroom cream sauce.
- Store leftover chicken and sauce together in an airtight container in the refrigerator for up to 3 days. Reheat gently and add a small splash of broth or cream if the sauce becomes too thick.
