This Campbell’s cream of mushroom chicken casserole recipe turns a basic can of soup into a rich, golden dish with tender chicken, crispy breadcrumbs, and layers of savory flavor—all in one pan and 30 minutes.

The secret lies in layering ingredients strategically—starting with tender chicken, then the creamy soup base, and finishing with a golden cheese crisp that seals in all the flavors.

You'll achieve that perfect crispy cheese topping without needing a broiler, and the creamy mushroom sauce will coat every bite of chicken and pasta. The best part? It's customizable—add fresh peas, spinach, or herbs to make it your own.

By the time it emerges from the oven, you'll have a golden, bubbling casserole with tender chicken, perfectly cooked pasta, and a crispy cheese layer that's impossible to resist. The aroma alone will have everyone at the table asking what's for dinner.

This is comfort food at its finest—warm, inviting, and guaranteed to disappear quickly. Let's get started with the exact steps that make this recipe work every time.

Whether you're feeding a family of four or prepping for leftovers, this casserole scales beautifully while maintaining its restaurant-quality texture and flavor. The layering technique ensures each component stays in place, and the cheese crisp adds a satisfying crunch that balances the creamy soup base.

Serve with a simple side salad or crusty bread to complete the meal. Here's how to assemble it like a pro.

Ingredients for campbell's cream of mushroom chicken casserole

The classic comfort casserole starts with just twelve ingredients—simple, familiar, and foolproof.

The Campbell's Cream of Mushroom Soup is the foundation—stick with the condensed version for the right consistency. For chicken, boneless, skinless breasts work best; thighs can make the dish too greasy. Pre-cutting the chicken into 1-inch cubes ensures even cooking. Uncooked egg noodles are essential here—they absorb the creamy sauce perfectly. If you prefer another pasta shape, use elbow macaroni instead. For the cheese, sharp cheddar delivers that perfect balance of tang and creaminess, but Monterey Jack works well too if you prefer something milder. Panko breadcrumbs create the ideal crispy topping—don't substitute regular breadcrumbs, which won't hold up as well.

No Campbell's soup? Homemade mushroom sauce works just as well—sauté mushrooms in butter, add flour to thicken, then deglaze with milk and chicken broth. Short on cheddar? Parmesan or Gruyère add great depth, though the flavor will shift slightly. The butter and milk mixture should be smooth—whisk vigorously to avoid lumps. For extra richness, add 2 tbsp sour cream to the sauce. If you're watching sodium, reduce the salt to 1/4 tsp and use low-sodium chicken broth instead of water when thinning the soup. The garlic powder and black pepper should be freshly ground for the best flavor—pre-ground spices lose potency quickly. For a pop of color, add a pinch of paprika to the breadcrumb topping.

This casserole reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes to restore crispiness. Store leftovers in the fridge for up to 4 days or freeze for 3 months. Portion into individual baking dishes before freezing for easy reheating. The cheese topping browns best when broiled for 2-3 minutes at the end—keep an eye on it to avoid burning. For meal prep, assemble the dish a day ahead and refrigerate uncovered so the flavors meld before baking. The dried parsley can be omitted if you prefer a cleaner look, but it adds a nice fresh finish.

Step-by-step instructions for Campbell's cream of mushroom chicken casserole

Here's how to assemble this comforting, cheesy casserole with minimal effort and maximum flavor.

Cut the 1.5 lb boneless, skinless chicken breast into 1-inch cubes for even cooking. In a large skillet over medium-high heat, add 0.25 cup of the 0.5 cup butter and cook the chicken for 5-6 minutes until lightly browned and cooked through. Remove the chicken and set aside.

In the same skillet, add the 2 cups uncooked egg noodles and toast them for 2 minutes, stirring frequently, until they begin to turn golden. This step enhances their texture and removes excess starch. Transfer the noodles to a greased 9x13-inch baking dish and spread them evenly across the bottom.

Reduce the heat to medium and add the remaining 0.25 cup butter to the skillet. Stir in the 2 tbsp all-purpose flour and cook for 1-2 minutes until the mixture forms a light roux and smells nutty. Slowly whisk in the 0.5 cup milk and 2 cans Campbell's Cream of Mushroom Soup, stirring constantly to prevent lumps from forming.

Season the mixture with 0.5 tsp salt, 0.25 tsp black pepper, and 0.5 tsp garlic powder. Bring the sauce to a gentle simmer and let it thicken for 3-4 minutes until it coats the back of a spoon. Remove from heat and stir in the cooked chicken until evenly distributed.

Spread the chicken and sauce mixture evenly over the toasted noodles in the baking dish. Sprinkle the 1.5 cups shredded sharp cheddar cheese evenly across the top, pressing down gently to help it melt into the casserole. This ensures every bite has that rich, cheesy flavor.

Preheat your oven to 375°F. Bake the casserole uncovered for 20-25 minutes until the cheese is fully melted and the edges begin to bubble. The filling should be heated through and the cheese should have turned a deep golden color.

In a small bowl, mix together the 0.5 cup panko breadcrumbs, remaining 0.5 tsp salt, and 0.25 tsp black pepper. Drizzle the 0.5 cup melted butter over the breadcrumbs and toss until evenly coated. Sprinkle this mixture evenly over the top of the casserole.

Return the casserole to the oven and bake for an additional 5-7 minutes until the breadcrumb topping is golden brown and crispy. The aroma should fill your kitchen—this is your cue that it's ready. Let the casserole rest for 5 minutes before serving to allow the cheese to set slightly.

Before serving, sprinkle the 1 tbsp dried parsley evenly over the top for a touch of freshness and color. This casserole serves 4 and makes a hearty main dish perfect for family dinners or meal prep. The crispy breadcrumb topping contrasts beautifully with the creamy cheese filling and tender chicken.

Cut into squares and serve immediately while the topping is still crispy. The combination of creamy mushroom sauce, tender chicken, and cheesy noodles creates a satisfying, comforting dish that's sure to please.

Perfect pairings for this dish

Classic Side Salad

Toss together a simple arugula salad with 2 tbsp olive oil, 1 tbsp balsamic vinegar, and a pinch of salt to cut through the richness.

The peppery bite refreshes your palate perfectly. I like adding ¼ cup sliced almonds for crunch and ½ cup cherry tomatoes for sweetness. 🥗

Crusty Bread Basket

Serve warm sourdough bread or a baguette on the side for soaking up any leftover sauce. Toast slices in the oven for 3-5 minutes at 375°F until golden, then brush with garlic butter. The crusty texture contrasts beautifully with the creamy casserole.

Light Vegetable Accompaniment

Steamed green beans with a sprinkle of lemon zest and toasted almonds add freshness. Toss 1 lb green beans with 1 tbsp melted butter and ½ tsp lemon pepper after steaming for 5 minutes. The acidity balances the dish's richness.
