Ingredients for campbell's cream of mushroom chicken casserole
Pantry staples meet restaurant-quality texture in this Campbell's Cream of Mushroom Chicken Casserole.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Boneless Chicken Breast 🍗 | 2 ½ lb | Cut into 1-inch cubes |
| Uncooked Egg Noodles 🍝 | 12 oz | Medium or wide egg noodles |
| Celery Stalks 🧅 | 1 whole | Trimmed, cut into 2-inch pieces |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, sharp variety |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Garlic Cloves 🧄 | 2 cloves | Minced for flavor |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |

The Campbell's cream of mushroom soup serves as the flavor foundation here, so opt for the condensed version—it delivers more concentrated flavor without excess liquid. Costco or Walmart typically stock bulk cans at the best price, though any grocery store will carry them. For the chicken, boneless, skinless breasts ensure tender results; cutting them into uniform 1-inch cubes guarantees even cooking. The celery crown demands fresh, crisp stalks—avoid woody or yellowed pieces that won't crisp properly. If your celery is particularly large, trim the base and use the leafy tops for garnish instead of discarding them.
No Campbell's soup? Homemade mushroom cream sauce works beautifully—simmer mushrooms, garlic, and thyme in butter, then blend with milk and a splash of cream. Substituting chicken thighs for breasts adds richness but may require adjusting baking time. For the celery crown, arrange stalks tightly in a circular pattern during the final 10 minutes of baking to ensure even crisping. The sharp cheddar should be freshly shredded—pre-shredded cheese contains anti-caking agents that prevent proper melting. If you prefer a lower-fat option, reduce the cheese by one-third and add an extra 0.25 cup of milk**
This casserole reheats beautifully—cover with foil and bake at 350°F for 20 minutes to restore crispiness. Store leftovers in an airtight container for up to 4 days, though the celery crown loses its crunch after 2 days. For freezing, bake without the celery crown, let cool completely, then freeze for up to 3 months. The celery crown can be added fresh after reheating. Portion into individual servings before freezing for quick meals—simply reheat and top with fresh parsley for a restaurant-worthy presentation.
Why You'll Love This Recipe

- Savory Umami Bomb: Between us, the Campbell’s soup alone brings the flavor—earthy mushrooms, rich broth, and that little kick of garlic. Add tender chicken and the celery’s crisp bite, and you’ve got a dish that tastes like it simmered for hours, not 30 minutes.
- Lunchbox Hero: Honestly, this is my go-to for meal prep. The leftovers reheat beautifully, and the creamy texture holds up better than takeout. Pack it in a container, and your kid (or you) will think you slaved over it—no one will guess it’s from a can of soup.

Step-by-step instructions for Campbell's cream of mushroom chicken casserole
Master this one-pot technique for a creamy, crisp-topped casserole that delivers restaurant-quality texture.
Prepare the Chicken and Celery Crown
Cut the 2.5 lb boneless chicken breast into 1-inch cubes—uniform size ensures even cooking. Season each piece generously with 1 tsp of the 1.5 tsp kosher salt and ¼ tsp of the 0.5 tsp black pepper. Set aside in a bowl.
Trim the 1 whole celery stalk and slice into 2-inch pieces. Arrange these celery pieces in a circular pattern on top of a 9x13-inch baking dish, creating a "crown" that will crisp beautifully during baking. This technique adds visual appeal and a satisfying textural contrast to the creamy filling.
Create the Creamy Base
In a large skillet over medium heat, melt the 0.5 cup butter. Add the 2 minced garlic cloves and cook for 30 seconds until fragrant—this prevents raw garlic flavor in the finished dish. Sprinkle in the 2 tbsp all-purpose flour and stir vigorously for 1-2 minutes to create a roux. This will thicken our sauce beautifully.
Gradually whisk in the 0.5 cup milk, stirring constantly to prevent lumps from forming. Once smooth, remove from heat and stir in the 2 cans Campbell's Cream of Mushroom Soup and 0.5 tsp dried thyme. The mixture should be velvety and well-combined, with a rich mushroom aroma that fills your kitchen.
Assemble the Casserole
Cook the 12 oz uncooked egg noodles according to package instructions until al dente, then drain and rinse briefly under cool water to stop the cooking process. Spread half of the noodles evenly across the bottom of your prepared baking dish, creating a base that will soak up the creamy sauce.
Arrange the seasoned chicken cubes evenly over the noodles, then pour the creamy mushroom mixture evenly over the top. Sprinkle the remaining half of the noodles over the chicken, then cover with the 1.5 cups shredded sharp cheddar cheese. The cheese will melt into a golden blanket during baking, creating that coveted crispy top.
Bake to Golden Perfection
Preheat your oven to 375°F. Bake the casserole uncovered for 25 minutes, then increase the heat to 425°F. Continue baking for an additional 15-20 minutes until the cheese is deeply golden brown and the celery crown is crisp around the edges—this high-heat finish creates that satisfying contrast of textures.
Remove from oven and let rest for 5 minutes before serving. The internal temperature should reach 165°F when checked in the thickest part of the chicken. Garnish with the 0.25 cup chopped fresh parsley just before serving to add freshness and vibrant color.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- POACH CHICKEN FIRST: Skip the raw chicken in the casserole—it’ll turn rubbery. Poach the sliced breasts in simmering water (or broth) for 12-15 minutes until they hit 165°F, then shred or dice. Cold chicken absorbs the creamy sauce better, and you won’t end up with a gray, overcooked mess. (Yes, even if you’re impatient like me.)
- SAUTE CELERY UNTIL SOFT: Don’t just chop and dump the celery. Cook it in butter or oil for 5-6 minutes until it’s barely al dente—it’ll melt into the sauce instead of sitting like crunchy sticks. I learned this the hard way when my first batch looked like a sad, watery soup.
- STIR IN NOODLES LAST: Toss the uncooked egg noodles into the hot casserole right before baking, not when you mix the soup and milk. They’ll absorb the liquid faster this way and cook through evenly without turning mushy. (And yes, you can use regular pasta if you’re in a pinch—but it won’t be the same.)
- THICKEN WITH CORNSTARCH: If the sauce looks too thin after mixing, whisk in 1 teaspoon cornstarch with a splash of cold milk before adding it to the casserole. It’ll give the finished dish that perfect, velvety texture without making it gluey. My grandmother swore by this, and she was right.
Make-ahead tips for campbell's cream of mushroom chicken casserole
Prep Ahead Strategy
I always start by prepping the chicken and celery crown the night before—this cuts active cooking time by half. Season the 1-inch chicken cubes with salt and pepper, then store them in an airtight container with a paper towel to absorb any moisture.
For the celery crown, arrange the 2-inch celery pieces in your baking dish and refrigerate until ready to bake. This keeps everything fresh and ready for assembly. 💡
Make-Ahead Assembly
Assemble the casserole up to 24 hours ahead and refrigerate uncovered. The noodles will soften slightly, but the flavors meld beautifully overnight. When ready to bake, simply cover with foil and bake at 375°F for 5 minutes to warm through, then proceed with the high-heat finish.
I swear by this method—it's how my grandmother made her famous casseroles.
Freezer-Friendly Base
For maximum convenience, prepare everything except the celery crown and freeze the assembled casserole (without baking). Wrap tightly in plastic wrap followed by aluminum foil to prevent freezer burn.
When ready to bake, thaw overnight in the fridge, then add the celery crown and bake as directed. The celery will crisp perfectly during the high-heat finish. ❄️
Portion for Meal Prep
Divide the baked casserole into individual portions and store in airtight containers. Reheat covered with a damp paper towel in the microwave for 2-3 minutes, then broil for 2-3 minutes to restore crispiness.
I love this for busy weeknights—just grab and reheat while I prep the rest of dinner. The leftovers actually taste better the next day!
Celery Crown Secret
If you're making this ahead, skip adding the celery crown until the final 10 minutes of baking. Arrange the celery pieces in a circular pattern right before the high-heat finish to ensure perfect crisping.
This is the real game-changer—it transforms a simple casserole into something that looks and tastes restaurant-worthy. 🌟
Garnish Just Before Serving
Fresh parsley isn't just for looks—it adds a bright, herbaceous note that cuts through the richness. Chop the 0.25 cup parsley right before serving to keep it vibrant. I also like adding a sprinkle of crushed black pepper** right from the grinder for that fresh-grated kick.
The contrast of textures and flavors makes every bite feel special.

Frequently asked questions
Can I use frozen chicken instead of fresh?
Thaw the chicken completely in the refrigerator first—never at room temperature. Pat it dry thoroughly before cubing to ensure the crispy celery crown forms properly during baking. Frozen chicken works just as well but requires this extra prep step.
Why did my celery crown turn mushy instead of crispy?
This usually happens when the celery isn't fresh or when it's added too early. Use crisp, firm stalks and arrange them in the final 10 minutes of baking at 425°F. For extra insurance, brush the celery lightly with oil before baking. The high heat is key to achieving that perfect crunch!
Can I make this recipe in a smaller baking dish?
Yes, but you'll need to adjust the quantities. For a 9x9-inch dish, reduce the recipe by about 25% and use 1.5 cups of noodles and 1 can of soup. The baking times remain the same, but the celery crown may be smaller. The flavor will be just as rich—just expect smaller portions.
What's the best way to reheat leftovers?
Cover the casserole with foil and bake at 350°F for 20 minutes to restore moisture. For the crispy celery crown, add fresh celery pieces during the last 5 minutes of reheating. Microwaving works too—just cover with a damp paper towel for 2-3 minutes, then broil for 2 minutes to crisp the top.
Can I substitute another type of pasta?
Egg noodles work best for their slightly chewy texture, but you can use penne or rotini if preferred. Avoid delicate pastas like angel hair—they'll turn mushy during baking. Cook them al dente and rinse briefly to prevent overcooking. The flavor will still be delicious, though the texture may differ slightly.
