Ingredients for campbell's cream of mushroom chicken casserole
Pantry staples meet restaurant-quality technique for this cheesy, crisp-topped casserole masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 2 ½ lb | Cut into 1-inch cubes for even cooking |
| Egg Noodles 🍝 | 2 cups | Uncooked, medium width preferred |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Heavy Cream 🥛 | ½ cup | Full-fat for rich texture |
| Shredded Sharp Cheddar Cheese 🧀 | 2 cups | Freshly shredded, not pre-shredded |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, fine texture |
| Panko Breadcrumbs 🍞 | ¾ cup | Light and crispy preferred |
| Fresh White Button Mushrooms 🍄 | 1 cup | Sliced, for extra texture |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 3 cloves | Minced, for aromatic depth |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crispy topping |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground for best flavor |
| Milk 🥛 | ¼ cup | Whole milk for creaminess |
The chicken is the foundation—boneless, skinless breasts cut into even cubes cook perfectly without drying out. Costco or butcher sections often have pre-cubed chicken, but if not, grab a whole breast and slice it yourself. For the cheeses, freshly shredded sharp cheddar makes all the difference (pre-shredded gets gummy when baked). Parmigiano-Reggiano for the Parmesan adds depth—skip the pre-grated stuff. The mushrooms? Fresh white buttons from the grocery store's produce section work best; canned mushrooms add moisture but lack texture. Pro tip: Toast your panko in a dry pan for 2 minutes before using—it gets extra crispy.
No Campbell's soup? Homemade mushroom cream sauce (mushrooms sautéed in butter, blended with cream and a splash of milk) works beautifully. Short on sharp cheddar? Monterey Jack or Gouda blends well. The panko topping too heavy? Swap for crushed potato chips or cornflakes for a lighter texture. For extra richness, stir 2 tbsp sour cream into the soup mixture. The egg noodles can be any shape—fettuccine or penne work too, but medium-width holds up best in baking. And if you're prepping ahead, cook the noodles al dente (1 minute less than package says) so they don't turn mushy when baked.
This casserole reheats like a dream—350°F for 20 minutes covered with foil, then 5 minutes uncovered to crisp the top. Keeps for 4 days in the fridge, freezes for 3 months (thaw overnight in the fridge). For meal prep, assemble the casserole up to a day ahead and refrigerate uncovered—it develops even more flavor. The cheese topping? Broil for 2-3 minutes at the end if you want it extra crispy. Leftovers? Double the batch—it disappears fast.

Step-by-step instructions for creamy mushroom chicken casserole
Here's how to create that perfect cheesy, crisp-topped masterpiece every time.
Prep the Chicken and Sauté the Aromatics
Cut the 2.5 lb boneless, skinless chicken breast into 1-inch cubes for even cooking. In a large skillet, melt 0.25 cup milk and 0.5 cup unsalted butter over medium heat. Add the 1 whole yellow onion (diced) and 1 cup fresh white button mushrooms (sliced), cooking for 5-6 minutes until softened and the onions turn translucent.
Stir in the 3 cloves garlic cloves (minced) and 1 tsp dried thyme, cooking for 30 seconds until fragrant. This aromatic base will infuse the entire casserole with deep flavor. Remove the mixture from the skillet and set aside for now—it's ready to become the heart of your dish.
Cook the Noodles and Build the Casserole Base
In a separate large pot, bring 6 cups water to a rolling boil and add 2 cups egg noodles. Cook according to package instructions until al dente—about 8-10 minutes. Drain well, then return the noodles to the pot and toss with 1.5 tsp salt and 1 tsp black pepper. The noodles should be hot when you combine them with the other ingredients.
In a large mixing bowl, combine the cooked noodles with the sautéed onion-mushroom mixture. Add 2 cans Campbell's cream of mushroom soup and 0.5 cup heavy cream, stirring until everything is evenly coated. The mixture should be thick and creamy—this is the foundation of your casserole's rich texture.
Layer and Assemble the Casserole
Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish to prevent sticking. Spread half of the noodle mixture evenly into the bottom of the dish. Sprinkle 1 cup shredded sharp cheddar cheese and 0.25 cup parmesan cheese over the first layer, then add the remaining noodle mixture. Top with another 1 cup shredded sharp cheddar cheese and 0.25 cup parmesan cheese.
Here's the secret to that perfect crispy top: In a small bowl, mix 0.75 cup panko breadcrumbs with the remaining 0.25 cup parmesan cheese. Sprinkle this mixture evenly over the top of the casserole. The panko will create a golden, crunchy crust that contrasts beautifully with the creamy layers below.
Bake to Golden Perfection
Transfer the casserole to the preheated oven and bake uncovered for 25-30 minutes until the top is golden brown and the edges begin to bubble. The cheese should be fully melted, and the panko topping should be crispy enough to snap when touched.
For the final touch, let the casserole rest for 5-10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve. The result? A creamy, cheesy, mushroom-infused casserole with a crispy, golden top that will have everyone asking for seconds.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- COOK CHICKEN UNTIL 165°F: I learned this the hard way—undercooked chicken in this casserole turns rubbery when it hits the creamy sauce. Use a meat thermometer and pull it when it hits 165°F, even if it looks underdone. The residual heat in the oven will finish it off while keeping it tender.
- TOSS NOODLES IN MELTED BUTTER: Skip the dry noodles—toss them in 1 tablespoon of melted butter before mixing with the soup. This prevents that sad, dry noodle texture at the bottom and makes sure every bite is creamy, not gummy. (Yes, even if you're impatient like me.)
- WHISK SOUP AND CREAM FIRST: Don’t just dump the heavy cream into the soup and stir. Whisk them together first, then mix into the soup. This creates a smoother, richer sauce instead of little cream blobs that curdle when baked. Trust me, your casserole will look (and taste) like it came from a restaurant.
- ADD CHEESE LAST, THEN STIR: Sprinkle the cheddar on top after the casserole is mostly baked, then stir it into the sauce before serving. This keeps the cheese from turning into a grainy, baked-on crust. If you’re serving it straight from the dish, at least stir the bottom layer back in—your guests will notice the difference.
Dietary considerations for these flavors
Gluten-Free Adaptations
Skip the egg noodles and use gluten-free pasta like Barilla or Jovial—both hold up well in baking. For extra security, I swap in cauliflower rice (cooked until tender) or quinoa for a grain-free option. Just make sure to cook it thoroughly so it doesn’t stay crunchy in the oven. 🌱
Dairy-Free Options
Replace the sharp cheddar with dairy-free cheddar shreds (like Violife or Daiya) and use cashew cream instead of heavy cream. For the panko topping, mix ½ cup crushed gluten-free cornflakes with ¼ cup nutritional yeast to mimic the cheesy flavor. The texture stays crispy, just without the dairy.
Lower-Carb Swaps
For a keto-friendly version, replace egg noodles with shredded zucchini (sautéed until tender) or cauliflower rice. Use cream of mushroom soup (check for no added sugar) and thicken it with xanthan gum if needed. Top with crushed pork rinds instead of panko for a crispy, carb-free crust.
Allergen-Friendly Tips
If nut allergies are a concern, swap cashew cream for coconut cream (full-fat, canned). For soy-free needs, ensure your Campbell’s soup is soy-free (some varieties contain soy lecithin). Always double-check labels—hidden allergens sneak into pantry staples more often than you’d think. 🚨
Lactose-Sensitive Fixes
Use lactose-free heavy cream and lactose-free cheeses (like Green Valley Organics) to keep the creamy texture without the digestive discomfort. The panko topping stays the same, but the cheesy layers won’t upset sensitive stomachs. Trust me, it’s a game-changer for family dinners!

Frequently asked questions
Can I use rotisserie chicken instead of fresh chicken breast?
Shredded rotisserie chicken works perfectly and saves time. Just measure out 2.5 lbs of cooked, cooled chicken and chop it into 1-inch pieces to mimic the texture. The flavor will be even richer since rotisserie chicken often comes seasoned with herbs.
How do I prevent the cheese topping from getting soggy?
Toast your panko breadcrumbs in a dry pan for 2 minutes before mixing with cheese. Also, bake the casserole uncovered for the first 20 minutes, then cover with foil for the last 5-10 minutes to melt the cheese without steaming the topping. The crispy texture depends on this step!
Can I make this casserole ahead of time?
Yes! Assemble it completely (including the cheese topping) up to 24 hours ahead and refrigerate uncovered. The flavors develop beautifully overnight. When ready to bake, add 10 extra minutes to the baking time. For freezing, assemble without baking, wrap tightly, and freeze for up to 3 months. Thaw overnight before baking.
What's the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 20 minutes, then uncover and broil for 2-3 minutes to restore crispiness. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals until warm. The texture won't be as crispy as fresh, but the flavors stay rich.
Why did my casserole turn out too watery?
This usually happens if the noodles weren't drained well or too much liquid was added. Next time, drain noodles thoroughly and pat dry with a towel. Also, reduce the heavy cream to ¼ cup if your soup is particularly thin. For extra insurance, let the assembled casserole sit at room temperature for 10 minutes before baking to help liquids absorb.
