Ingredients for campbell's cream of mushroom chicken casserole
Pantry staples plus a few fresh ingredients transform into nostalgic comfort food.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Cooked Chicken Breast 🍗 | 2 cups | Diced, boneless, skinless |
| Mushrooms (white) 🍄 | 1 cup | Sliced, fresh or canned |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, mild or sharp |
| Milk 🥛 | ¼ cup | Whole milk preferred |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Yellow Onion 🧅 | ½ cup | Diced, medium size |
| Garlic Cloves 🧄 | 2 cloves | Minced, fresh preferred |
| Butter 🧈 | 2 tbsp | Unsalted, for sautéing |
| Breadcrumbs 🍞 | ¼ cup | Plain or panko style |
| Green Onions 🧅 | 2 whole | Sliced, for garnish |
The Campbell's soup is the base here, but don't skimp on the mushrooms. Fresh white mushrooms from the grocery store's produce section add real texture—Trader Joe's and Whole Foods carry the best quality. If you're using canned mushrooms, drain well and pat dry. The chicken should be fully cooked and diced into bite-sized pieces (about 1-inch cubes). For extra flavor, season the chicken with a pinch of salt and pepper before adding it to the casserole. The sharp cheddar is non-negotiable—it needs to melt beautifully, so Kraft or Cabot are solid choices. If you're using pre-shredded cheese, give it a quick stir to break up any clumps.
No Campbell's soup? Homemade cream of mushroom soup works too—just simmer mushrooms, onion, garlic, and chicken broth with a splash of cream. Short on mushrooms? Cream of celery soup is a decent swap, though the flavor will be different. The heavy cream can be swapped for half-and-half or sour cream if you're watching fat, but the texture won't be as rich. For the breadcrumbs, panko gives extra crunch, but plain breadcrumbs work fine. If you're adding extra veggies like broccoli or peas, cook them first and stir into the casserole before baking—no need to pre-chop them small since they'll soften during baking.
This casserole reheats beautifully—just cover with foil and warm in the oven for 10-15 minutes. It keeps well in the fridge for 4-5 days, though it tastes best within the first couple of days. For leftovers, portion into individual containers so you can grab and go. The sauce thickens as it sits, so if it seems too thick after baking, stir in a splash of milk or cream before serving. Double the recipe if you're feeding a crowd—it's that good.

Step-by-step instructions for creamy mushroom chicken casserole
Here's how to make this rich, cheesy casserole with perfect texture every time.
Sauté the Aromatics for Maximum Flavor
Melt the 2 tablespoons butter in a large skillet over medium heat. Add the 0.5 cup diced yellow onion and cook for 3-4 minutes until softened and translucent. Push the onions to the side and add the 2 minced garlic cloves, cooking for 30 seconds until fragrant.
Here's the thing—don't let the garlic burn. It should smell amazing but not bitter. If it starts to darken too quickly, reduce the heat slightly. Add the 1 cup sliced mushrooms and cook for 5-6 minutes until they release their moisture and begin to brown. This step builds the flavor foundation for your entire casserole.
Create the Creamy Mushroom Sauce
In a separate bowl, whisk together the 2 cans Campbell's Cream of Mushroom Soup, 0.5 cup heavy cream, 0.25 cup milk, and 1 tablespoon all-purpose flour until smooth. Pour this mixture into the skillet with the sautéed vegetables and stir well to combine.
Bring the mixture to a gentle simmer over medium heat, stirring frequently for 3-4 minutes until it thickens slightly. Taste and adjust seasoning with the 0.5 teaspoon salt and 0.25 teaspoon black pepper. The sauce should be rich and velvety—this is where the magic happens. If it's too thick, add a splash of milk to reach your desired consistency.
Combine with Chicken and Cheese
In a large mixing bowl, combine the cooked mushroom sauce with the 2 cups diced cooked chicken breast and 1.5 cups shredded sharp cheddar cheese. Stir gently until the cheese begins to melt and the chicken is evenly distributed throughout the mixture. You want the cheese to melt completely but not get stringy.
This is the moment that matters: the cheese should be fully incorporated but still have a slight meltiness to it. If you notice the mixture getting too thick, you can add a little more milk to help it come together smoothly. The texture should be creamy but still spreadable.
Assemble and Bake to Perfection
Preheat your oven to 350°F. Grease a 9x13-inch baking dish and spread the chicken mixture evenly inside. Sprinkle the 0.25 cup breadcrumbs evenly over the top for a crispy finish. Bake uncovered for 25-30 minutes until the top is golden brown and the edges are bubbly.
Watch for the breadcrumbs to turn golden—they should look toasted and crispy, not pale. If the top isn't browning enough, broil for 1-2 minutes at the end (watch closely to avoid burning). The internal temperature should reach 165°F when checked with a meat thermometer.
Rest and Serve with Fresh Garnish
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting time allows the juices to redistribute and the cheese to set slightly, making each bite more flavorful and less runny.
Slice the 2 whole green onions into thin rings and sprinkle them over the top just before serving. The fresh green onions add a bright contrast to the rich, cheesy casserole. Serve warm with crusty bread or a simple side salad for a complete meal that's sure to impress.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- Sauté the mushrooms first: The soup’s flavor gets lost if you just dump raw mushrooms into the mix. Sear them in a dry pan with a splash of water for 5 minutes until they release their juices—this adds depth the canned soup can’t provide.
- Use leftover chicken, shredded: Freshly cooked chicken stays too clumpy. Shred cold, leftover chicken instead—it breaks down better, soaks up the sauce evenly, and saves you from drying out the casserole while it bakes.
- Skip the watery soup stretch: Heavy cream and Campbell’s soup already make this dish rich. If the mixture looks too thick, thin it with a splash of chicken broth instead of milk—it won’t dilute the mushroom flavor as much.
- Bake uncovered, then cover: Let the top brown for 10 minutes uncovered first—this prevents a soggy cheese crust. Then tent with foil and finish baking to melt the cheddar evenly without burning. (Yes, even if it looks weird halfway through.)
Health benefits of this dish
Protein-Packed Comfort
The chicken in this casserole provides a solid 25-30 grams of protein per serving, making it a satisfying option for muscle maintenance or post-workout recovery. I always use boneless, skinless chicken breast for lean protein, but you could swap in rotisserie chicken for convenience.
The combination of protein and complex carbs from the breadcrumbs keeps you full for hours—perfect for weeknight dinners when you need staying power. 💪
Mushroom Antioxidants
White mushrooms add selenium and vitamin D—nutrients that support immune function and bone health. A 1-cup serving provides about 20% of your daily selenium needs, an important antioxidant. I like to use fresh mushrooms from the farmers market because they have more vibrant flavor and texture than canned.
The sautéing step also helps preserve these nutrients while building depth of flavor.
Healthy Fat Balance
The heavy cream and cheese in this recipe provide saturated fats that contribute to the creamy texture, but they're balanced by the protein and fiber from the chicken and mushrooms. For a lighter version, I sometimes swap half the heavy cream for Greek yogurt—it adds tanginess while cutting calories.
The breadcrumbs add a satisfying crunch without significant nutritional drawbacks, though panko has slightly more fiber than plain breadcrumbs.
Cheese Nutrition
Sharp cheddar contributes calcium and phosphorus for bone health, with 1.5 cups providing about 30% of your daily calcium needs. The cheese also adds fat-soluble vitamins like A and K2.
I always use real shredded cheese (not pre-shredded) because it melts more smoothly and doesn't contain anti-caking agents that can make the texture grainy. The meltiness of the cheese is what makes this casserole feel indulgent while still being a complete meal.
Meal Prep Advantage
This casserole reheats well while maintaining most of its nutritional benefits, making it ideal for meal prep. The protein and fiber content helps stabilize blood sugar levels, preventing energy crashes that often come with carb-heavy meals.
I like to portion leftovers into individual containers so I can grab a serving for lunch without reheating the whole dish. The flavors actually improve overnight as the ingredients meld together—this is one of those rare casseroles that tastes better the next day. 💡

Frequently asked questions
Can I use rotisserie chicken instead of cooked chicken breast?
Rotisserie chicken works perfectly and saves time. Just remove the skin and bones, then dice the meat into 1-inch cubes. The flavor will be slightly richer, but the texture remains tender. This swap is especially helpful when you're short on time or want to simplify prep.
Why does my casserole look watery after baking?
Watery texture usually means the sauce needs more thickening. Try mixing 1 tablespoon cornstarch with 2 tablespoons cold water and stirring it into the sauce before baking. If the issue persists, reduce the milk slightly next time—too much liquid prevents proper thickening. Always bake until bubbly at the edges for the best results.
Can I make this casserole ahead of time?
Yes! Assemble the dish up to 24 hours ahead and refrigerate uncovered. When ready to bake, add 10-15 extra minutes to the baking time (cover with foil if needed). The flavors actually deepen overnight, making it taste even better the next day. Just avoid adding breadcrumbs too early—they'll get soggy.
What's the best way to reheat leftovers?
Cover the casserole with foil and reheat in a 350°F oven for 15-20 minutes until warmed through. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals on medium power, stirring between each interval. The oven method preserves the creamy texture best.
Can I add other vegetables to this recipe?
Certainly! Try adding ½ cup frozen peas or 1 cup chopped broccoli—just cook them first and stir into the casserole before baking. For heartier veggies like bell peppers or zucchini, sauté them with the onions and mushrooms. The key is to pre-cook any veggies that might release excess moisture during baking.
