Ingredients for campbell's cream of mushroom chicken casserole
Sixteen ingredients for a nostalgic casserole that delivers restaurant-quality comfort food with minimal effort.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Breast 🍗 | 2 lbs | Boneless, skinless, cut into bite-sized pieces |
| Cream of Mushroom Soup 🍄 | 2 cans | Condensed, Campbell's brand preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for rich texture |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Butter 🧈 | ½ cup | Unsalted, cubed |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Fresh Mushrooms 🍄 | 1 lb | Sliced, cremini or white |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Parsley 🌿 | 1 tbsp | For garnish, or fresh if available |

| Unsalted Butter 🧈 | 2 tbsp | For topping, melted |

The Campbell's cream of mushroom soup is the backbone of this dish—it's what brings back those childhood flavors. Grab the classic condensed version from any grocery store, but check the expiration date; older cans can make the sauce taste flat. For the mushrooms, fresh cremini or white are ideal, but frozen works in a pinch—just thaw and pat dry. The chicken should be freshly cut into even pieces (about 1-inch cubes) so it cooks uniformly. Pro tip: Costco often has pre-cut chicken breasts at a great price, saving you time. If you're using pre-cooked chicken, make sure it's fully cooled before adding to the casserole to avoid steaming the sauce.
No Campbell's soup? Homemade mushroom sauce works just as well—sauté mushrooms, onions, and garlic in butter, then add flour to make a roux before incorporating milk and cream. Short on heavy cream? Half-and-half plus a splash of milk keeps it creamy without breaking the bank. The butter matters here—unsalted is key so you control the seasoning. For the golden top, melted butter plus breadcrumbs is non-negotiable; it's what creates that signature crispy finish. If you're out of panko, regular breadcrumbs toasted in a dry pan for 2 minutes will do the trick. The parsley is purely decorative, but it adds a fresh pop—dried works if that's what you've got.
This casserole reheats beautifully—4-5 days in the fridge with the top sealed tightly. For leftovers, cover with foil to prevent drying out. Freezes for up to 3 months, though the texture might get slightly soggy after thawing. I always make a double batch because it's that good—portion into individual containers for easy lunches. The best part? It smells amazing while it bakes, so set a timer and let that aroma fill your kitchen. Trust me, the whole house will know dinner's ready.

Step-by-step instructions for cream of mushroom chicken casserole
This one-pan method delivers a creamy, cheesy casserole with a golden breadcrumb topping every time.
Cook the Chicken and Sauté Vegetables
Heat the 0.5 cup butter in a large oven-safe skillet over medium-high heat. Add the 2 lbs chicken breast cut into bite-sized pieces and cook for 5-6 minutes, stirring occasionally, until the chicken is lightly browned on all sides and cooked through to an internal temperature of 165°F. Remove the chicken and set aside.
In the same skillet, add the 1 lb fresh mushrooms and 1 whole yellow onion diced. Cook for 4-5 minutes until the mushrooms release their moisture and begin to soften. Add the 3 cloves garlic cloves minced and cook for 30 seconds until fragrant. Sprinkle with 1 tsp salt and 0.5 tsp black pepper, then stir to combine.
Make the Creamy Sauce
Reduce the heat to medium-low and stir in the 2 tbsp all-purpose flour, cooking for 1 minute to remove the raw flour taste. Slowly pour in the 0.5 cup heavy cream and 0.5 cup milk, whisking constantly to prevent lumps. Stir in the 2 cans cream of mushroom soup and bring the mixture to a gentle simmer, allowing it to thicken for 3-4 minutes. The sauce should coat the back of a spoon and have a smooth, creamy consistency.
Return the cooked chicken to the skillet and stir gently to coat in the sauce. Remove from heat and fold in the 1.5 cups shredded cheddar cheese until fully melted and evenly distributed. Taste and adjust seasoning if needed.
Assemble and Bake the Casserole
Preheat your oven to 375°F. Spread the chicken and sauce mixture evenly in the skillet. Melt the 2 tbsp unsalted butter in a small microwave-safe bowl for 20-30 seconds until fully liquid, then stir in the 0.5 cup breadcrumbs and 1 tbsp dried parsley to form a crumb mixture.
Sprinkle the breadcrumb mixture evenly over the top of the casserole, pressing down lightly with a spatula to ensure even coverage. Bake for 20-25 minutes until the top is golden brown and the edges are bubbling. The casserole is done when the cheese is melted and the breadcrumbs are crispy.
Rest and Serve
Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the cheese to set slightly and makes it easier to slice. Serve warm, straight from the skillet, with a side of steamed vegetables or a fresh green salad.
The casserole should have a creamy, rich texture with a perfectly crispy breadcrumb topping. Each bite should deliver tender chicken, velvety mushroom sauce, and sharp cheddar cheese. If the top isn't crispy enough, broil for 1-2 minutes on high before serving.
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. Simmer diced chicken in salted water or broth for 12-15 minutes until just cooked, then drain and cool before mixing. I learned this the hard way when my first batch came out chewy, and now the texture is always tender.
- WHISK THE SOUP: Campbell’s soup thickens when cold. Before adding it to the cream mixture, whisk it vigorously to break up any lumps—especially if you’re using powdered soup. I was skeptical until I tried it; the sauce stays silky instead of grainy.
- DON’T OVERMIX THE CREAM: Once you stir in the heavy cream and milk, stop mixing after 10 seconds. Overworking it turns the sauce thin and watery. Fold just until combined—this keeps the casserole rich and cohesive.
- BAKE COVERED THEN UNCOVERED: Start with the foil on for the first 25 minutes to melt the butter and thicken the sauce. Then remove the foil for the last 10-15 minutes to let the top brown. My grandmother swore by this, and she was right: the edges get crispy without burning.
Serving suggestions for this recipe
Classic Side Pairings
This casserole pairs perfectly with crusty French bread—I grab a loaf from my local bakery with the crust still warm. The bread soaks up any stray sauce while adding a satisfying crunch. For a lighter option, a simple green salad with lemon vinaigrette cuts through the richness beautifully.
I toss 4 cups mixed greens with 2 tbsp olive oil, 1 tbsp lemon juice, and a pinch of salt. 🥗
Vegetable Boosters
Add steamed broccoli or roasted Brussels sprouts for extra nutrients. Toss 1 lb Brussels sprouts with 1 tbsp olive oil, ½ tsp garlic powder, and ¼ tsp black pepper, then roast at 400°F for 20 minutes until crispy. The earthy flavors complement the creamy casserole perfectly.
Potato Perfection
For a heartier meal, serve with garlic mashed potatoes. Boil 2 lbs Yukon Gold potatoes until tender, then mash with ½ cup butter, ½ cup warm milk, 1 tsp garlic powder, and ½ tsp salt.
The creaminess of the potatoes mirrors the casserole’s sauce, creating a match made in comfort food heaven. 🥔
Beverage Pairings
A bold red wine like Cabernet Sauvignon stands up to the dish’s richness, while a crisp white wine such as Sauvignon Blanc offers a refreshing contrast. For non-alcoholic options, iced tea with lemon or sparkling water with a splash of cranberry juice keeps things light.
My grandmother always served this with sweet tea—a Southern staple that never disappoints. 🍷
Make-Ahead Serving
If serving for a crowd, assemble the casserole in a 9x13-inch baking dish (instead of a skillet) for easier transport. Reheat covered at 350°F for 20-25 minutes until bubbly. For a buffet-style setup, serve the casserole family-style with small bowls of extra breadcrumbs and shredded cheese for customization. 🍽️
Leftovers Reinvented
Turn leftovers into casserole croquettes by shaping cold slices into balls, dredging in 1 egg and ½ cup breadcrumbs, then pan-frying until golden. For a quick lunch, serve over buttered noodles or toasted sourdough with a side of pickled vegetables for acidity.
My kids always ask for this when I make extra—it’s their favorite way to enjoy the leftovers! 💡

Frequently asked questions
Can I use rotisserie chicken instead of fresh?
Rotisserie chicken makes this a true 30-minute meal. Shred 2 cups of cooked chicken and stir it into the sauce after removing the skillet from heat. The flavor is just as rich, and you'll save time on prep. Just make sure the chicken is fully cooled before adding to avoid steaming the sauce.
Why did my casserole top turn soggy?
Soggy tops usually happen when the breadcrumbs aren't crisped enough or the casserole isn't baked long enough. For a foolproof crispy finish, broil for 1-2 minutes at the end of baking. Also, make sure your breadcrumbs are toasted in butter before adding to the top layer. This adds an extra barrier against moisture.
Can I make this vegetarian?
Swap the chicken for chickpeas or mushrooms—both work beautifully! Use 2 cups cooked chickpeas (or 1.5 cups canned, drained) and add them with the sauce. For extra protein, stir in ½ cup crumbled feta at the end. The creamy mushroom sauce will still be the star of the show.
How do I reheat leftovers without drying it out?
Cover the casserole tightly with foil and reheat at 350°F for 15-20 minutes. For extra moisture, add 1-2 tbsp milk or broth before reheating. If using the microwave, cover with a damp paper towel and heat in 30-second intervals to prevent rubbery chicken. Stir between each interval.
What's the secret to that perfect melty top?
Three things: butter, breadcrumbs, and patience. Mix the breadcrumbs with melted butter before topping, and press down lightly with a spatula. Bake until the edges are bubbling and the top is deep golden brown. The last 5 minutes of baking are critical—don't peek or open the oven door!
