Ingredients You’ll Need
You’ll be amazed at how a handful of staple ingredients create layers of flavor and texture in this Creamy Chicken Mushroom Noodle Bake. Each ingredient has its own special role—whether it’s adding richness, creating that craveable sauce, or bringing the whole dish together with a pop of color.
- Chicken breasts: Use boneless, skinless pieces for tender bites that soak up all the creamy goodness.
- Onion: Diced onion adds subtle sweetness and deepens the savory base of the casserole.
- Mushrooms: Sliced mushrooms give the bake a rich, earthy flavor and satisfying texture.
- Egg noodles: Their soft texture is perfect for absorbing the sauce; feel free to swap with gluten-free pasta if needed.
- Cream of mushroom soup: This shortcut ingredient brings creaminess and brings all the flavors together effortlessly.
- Sour cream: Adds tang and silkiness to make the sauce luxuriously smooth.
- Chicken broth: Infuses the whole dish with extra flavor and keeps things moist.
- Garlic powder: An easy way to add savory depth that wakes up all the other flavors.
- Salt and pepper: Essential seasonings for perfect seasoning and balance.
- Oil: Needed for sautéing the onions, mushrooms, and chicken so everything cooks up golden.
- Fresh parsley: Totally optional, but a sprinkle on top makes for a fresh, vibrant finish.
How to Make Creamy Chicken Mushroom Noodle Bake
Step 1: Prep the Oven and Ingredients
Start by preheating your oven to 350°F (175°C) so it’s hot and ready by the time your casserole is assembled. While that’s happening, chop your chicken, dice the onion, and slice those mushrooms—it’s all about making dinnertime as stress-free as possible.
Step 2: Sauté the Onion and Mushrooms
Heat a little oil in a large skillet over medium heat. Add the diced onion and cook until it turns translucent and fragrant, ensuring the flavor base is mellow and sweet rather than sharp. Toss in the mushrooms next and sauté until they soften and just start to brown. This brings out their deep, savory notes, which are absolute magic in this Creamy Chicken Mushroom Noodle Bake.
Step 3: Add and Cook the Chicken
Now, stir in your bite-sized chicken pieces. Sprinkle them with garlic powder, salt, and pepper right in the pan. Cook, stirring occasionally, until the chicken loses its pink color and starts to develop a light golden edge—it’ll finish cooking in the oven later, so don’t worry about it getting completely browned through at this stage.
Step 4: Pour in Chicken Broth and Simmer
Once your chicken is looking just right, pour in the chicken broth. Let everything simmer gently for a few minutes as the broth bubbles away, infusing the chicken and veggies with flavor and keeping them ultra juicy.
Step 5: Create the Creamy Sauce
Meanwhile, grab a bowl to combine the cream of mushroom soup and sour cream. Stir until smooth—this is your secret sauce for supreme creaminess. Add this mixture to the skillet and stir well so it coats every bit of chicken and mushroom, making sure nothing is left behind.
Step 6: Mix With Noodles and Transfer
Cook your egg noodles, but only until just shy of al dente (think: still a tad firm). This helps them stay perfectly textured in the oven. In your baking dish, mix the cooked noodles with the chicken and mushroom mixture. Stir everything together until the noodles are well coated and evenly distributed.
Step 7: Bake to Perfection
Cover the dish with foil to help everything steam and meld together, then bake for about 25 minutes. Remove the foil and continue baking another 10 to 15 minutes until the casserole is bubbly and just starting to turn golden on top. Let it sit for a few minutes before serving—everything will come together in creamy, irresistible harmony.
How to Serve Creamy Chicken Mushroom Noodle Bake

Garnishes
A flourish of freshly chopped parsley adds both color and a hint of freshness to this dish. If you’re feeling adventurous, a sprinkle of grated Parmesan or a few crispy fried onions on top also amps up the wow factor—let your taste buds lead the way!
Side Dishes
This Creamy Chicken Mushroom Noodle Bake pairs brilliantly with a crisp green salad tossed in a light vinaigrette, or some simply roasted carrots or broccoli for extra color and crunch. If you want to make it a full comfort-food feast, serve it alongside garlic bread or warm, fluffy rolls that are perfect for swiping up every last bit of that dreamy sauce.
Creative Ways to Present
Try serving individual portions in ramekins for an elevated dinner party feel, or bake the casserole in a cast iron skillet for rustic charm. If you’re prepping ahead for a potluck, transfer it to a travel-friendly dish and garnish with plenty of fresh herbs just before serving to liven up the look and flavor.
Make Ahead and Storage
Storing Leftovers
Let any leftover Creamy Chicken Mushroom Noodle Bake cool to room temperature before transferring it to an airtight container. It’ll keep happily in the fridge for up to 3 days, making your next lunch or dinner every bit as delectable (and easy!) as the first time around.
Freezing
If you want to freeze your casserole, assemble everything right up to the baking stage. Wrap the unbaked dish tightly in plastic wrap and then foil. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge, then bake as directed, adding a few extra minutes if needed to reach that delicious bubbly finish.
Reheating
For best results, reheat leftovers covered in a low oven (about 300°F) until hot and creamy again. A splash of milk or broth stirred in before reheating helps revive the sauce. You can also microwave individual servings, but do so in short bursts and stir often to keep the noodles from drying out.
FAQs
Can I use rotisserie chicken instead of cooking chicken breasts?
Absolutely! Shredded or chopped rotisserie chicken is a fantastic shortcut. Just fold it in with the mushrooms and sauce before baking for even faster prep with loads of flavor.
Can I substitute different vegetables?
Definitely. Spinach, peas, bell peppers, or even steamed broccoli would all be delicious additions. Just keep the quantities balanced so your Creamy Chicken Mushroom Noodle Bake stays perfectly creamy without getting overloaded.
How can I make this dish gluten-free?
Simply swap in gluten-free pasta for the egg noodles and use a gluten-free cream of mushroom soup. Check labels to make sure all your other ingredients are gluten-free, and you’re good to go!
What kind of mushrooms work best here?
Button or cremini mushrooms are classic, but use what you love. Portobello, shiitake, or even a wild mushroom blend will add more earthy, complex flavors to the bake.
Can I assemble this ahead of time?
Yes! You can assemble the casserole (without baking) up to 24 hours in advance. Cover and store in the fridge, then bake when you’re ready—just add a few extra minutes to the bake time if it’s going straight from the fridge to the oven.
