Ingredients for campbell's cream of mushroom chicken casserole
Pantry staples and a few fresh ingredients for that nostalgic cheesy mushroom casserole flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Chicken Breast 🍗 | 2 ½ lb | Cut into bite-sized pieces |
| Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, condensed |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Yellow Onion 🧅 | 1 whole | Diced small |
| Garlic Cloves 🧄 | 3 cloves | Minced finely |
| Fresh Mushrooms 🍄 | 8 oz | Sliced thin |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, sharp flavor |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For extra flavor |
| Breadcrumbs 🍞 | ½ cup | Panko preferred |
The chicken stays tender when cut into even pieces—about 1-inch cubes works best. Grab boneless, skinless breasts from the grocery store's meat counter (the pre-cut ones save time). For the mushrooms, cremini or baby bella add more depth than white mushrooms. The soup? Campbell's Condensed Cream of Mushroom is the classic choice, but any quality brand works. I always check the expiration date—this dish tastes best when everything's fresh.
No heavy cream? Half-and-half or evaporated milk works in a pinch (though it'll be slightly lighter). Short on mushrooms? Extra chicken broth adds body to the sauce. The flour is just for thickening—if you're sensitive to gluten, cornstarch works too. For the cheesy topping, sharp cheddar gives the best flavor, but Colby Jack or Monterey Jack are solid backups. The breadcrumbs? Panko stays crispier than regular breadcrumbs—worth the extra 50 cents.
This casserole reheats beautifully—350°F for 20 minutes brings it back to perfection. Leftovers keep for 4-5 days in the fridge, and it freezes well for up to 3 months. I always make a double batch—one for dinner, one for lunches. The topping gets crispy again when reheated, so don't skip it!
Why You'll Love This Recipe

Step-by-step instructions for cream of mushroom chicken casserole
This classic comfort dish delivers rich, creamy goodness with that perfect cheesy crunch on top.
Prepare the Chicken and Mushroom Mixture
Cut the 2.5 lb boneless chicken breast into bite-sized pieces, about ½-inch cubes. This size ensures even cooking and tender chicken throughout the casserole. In a large skillet, melt 0.5 cup butter over medium heat until it foams. Add the diced yellow onion and cook for 3-4 minutes until softened and translucent.
Increase heat to medium-high and add the 8 oz fresh mushrooms, sliced thin. Cook for 5-6 minutes until they release their moisture and begin to brown. Stir in the 3 cloves minced garlic and cook for 30 seconds until fragrant. This step builds the flavor foundation for your casserole.
Create the Creamy Sauce Base
Lower the heat to medium and sprinkle 0.25 cup all-purpose flour over the mushrooms. Stir constantly for 1-2 minutes until the flour is fully incorporated and the mixture thickens slightly. This creates a roux that will help thicken your sauce beautifully.
Slowly pour in 0.5 cup milk while whisking continuously to prevent lumps from forming. Cook for 2-3 minutes until the mixture smooths out. Add the 2 cans cream of mushroom soup and 0.5 cup heavy cream, stirring until fully combined. Bring to a gentle simmer and cook for 3-4 minutes until the sauce thickens to a creamy consistency.
Combine Chicken and Sauce
Transfer the chicken pieces to the skillet with the mushroom mixture. Add 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder, stirring to coat the chicken evenly. Let the mixture simmer for 5-6 minutes until the chicken is cooked through and reaches an internal temperature of 165°F. The chicken should be opaque with no pink remaining.
Remove the skillet from heat and let it cool slightly for 2-3 minutes. This brief resting period helps prevent the cheese topping from getting soggy when you assemble the casserole. Here's where the magic happens - the flavors meld together perfectly.
Assemble and Bake the Casserole
Preheat your oven to 375°F. In a 9x13-inch baking dish, spread the chicken and mushroom mixture evenly. Sprinkle 1.5 cups sharp cheddar cheese over the top, making sure every inch is covered. Press down gently to help the cheese adhere to the chicken.
In a small bowl, mix the 0.5 cup breadcrumbs with 0.5 cup butter, melted, until evenly combined. Sprinkle this mixture over the cheese layer, pressing down lightly with a spatula. This creates that perfect crispy topping we all love. Bake for 20-25 minutes until the top is golden brown and bubbly.
Rest and Serve
Remove the casserole from the oven and let it rest for 5-10 minutes. This resting period allows the cheese to set slightly and makes it easier to serve without losing that perfect cheesy topping. The casserole should be hot and bubbly with a golden, crispy top that contrasts beautifully with the creamy filling underneath.
Cut into squares and serve immediately. Each bite delivers tender chicken in a rich, creamy mushroom sauce with that satisfying crunch from the cheesy breadcrumb topping. This classic recipe stays true to the original while delivering restaurant-quality results in your own kitchen.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- Sear Chicken First: I learned this the hard way—tossing raw chicken straight into the soup mix makes for bland, rubbery bites. Sear the chicken breasts in a pan with oil for 3-4 minutes per side until golden before adding them to the casserole. The crust locks in flavor and keeps the meat juicy when it bakes.
- Sauté Onions Low and Slow: Onions burn faster than you’d think, and bitter onions ruin the creamy sauce. Cook them over medium-low heat for 8-10 minutes until soft and translucent, stirring often. If they start to stick, add a splash of water—better to deglaze now than regret it later.
- Skip the Watery Top: The recipe might call for broth or water, but trust me, you don’t need it. The soup and heavy cream already add enough liquid. A watery casserole turns soggy, and no one wants that. If the mix looks too thick, stir in a splash of cream—not water.
- Bake Until Golden: I used to pull this out as soon as the chicken hit 165°F, but the topping stayed pale and sad. Let it bake 5-10 minutes longer until the cheese (if using) or the breadcrumb topping turns golden. That’s when the flavor really sings—yes, even if the chicken’s technically done.
Serving suggestions for leftovers
Classic Side Pairings
This creamy casserole pairs beautifully with a simple green salad tossed in red wine vinegar and olive oil. I always use mixed greens with cherry tomatoes and shaved Parmesan for that fresh contrast.
The acidity cuts through the richness, balancing every bite. For a heartier option, serve with crusty French bread or warm dinner rolls to soak up all that creamy sauce. 🥗
Vegetable Companions
Roasted carrots or asparagus add color and nutrition to your plate. Toss them in olive oil, salt, and garlic powder, then roast at 425°F for 15 minutes until tender.
I love serving steamed broccoli with a sprinkle of lemon zest—it’s light enough to let the casserole shine. For a Southern touch, collard greens slow-cooked with smoked ham hocks make a perfect side.
Beverage Recommendations
A crisp white wine like Sauvignon Blanc or Chardonnay complements the creamy, cheesy flavors beautifully. For beer lovers, a light lager or wheat beer keeps the meal refreshing.
I often reach for iced tea with lemon or sparkling water with a splash of cranberry juice—both balance the richness without overpowering the dish. 🍷
Make-Ahead Serving Tips
This casserole reheats like a dream, so I always make extra for leftovers. Cover tightly with aluminum foil and refrigerate for up to 4 days. When reheating, cover with foil and bake at 350°F for 20-25 minutes—the topping crisps up again, just like fresh out of the oven.
For potlucks, serve in a glass baking dish to keep it warm and looking beautiful. 💡
Presentation Tricks
Use a wooden serving board or ceramic platter to elevate the dish—it adds warmth and makes it feel special. Garnish with fresh parsley or chives for a pop of color.
For a restaurant-style touch, arrange the casserole in the center of the table and serve with individual bowls for the sauce. I also love adding toasted almonds on top for extra crunch before serving.
Family-Friendly Touches
Kids love dipping their squares into sour cream or ranch dressing—it makes the meal more interactive. For picky eaters, serve the casserole with buttered noodles on the side so they can mix and match.
I’ve even turned leftovers into casserole sliders by cutting into small portions and serving on mini dinner rolls—it’s a hit at my house! 🌟
Nutrition facts
Frequently asked questions
Can I substitute chicken thighs for breasts in this recipe?
Chicken thighs add even more flavor and stay juicier than breasts. Use 2.5 lb boneless thighs instead, and reduce the baking time by 5 minutes since they cook faster. The skin-on version adds crispiness, but remove it if you prefer. Thighs work especially well if you're making a double batch for leftovers.
What's the secret to getting a crispy cheese topping?
Three things make all the difference: melted butter mixed with breadcrumbs, pressing the topping down gently before baking, and baking at 375°F until golden. For extra crunch, sprinkle 1 tablespoon cornstarch over the cheese layer before adding breadcrumbs. Also, let the casserole rest 5-10 minutes after baking—this helps the cheese set properly.
Can I make this casserole ahead of time?
This is one of the best make-ahead dishes! Assemble it completely (including the topping) and refrigerate uncovered for 24 hours before baking. The flavors deepen overnight, and the topping crisps up beautifully when baked. For longer storage, freeze the unbaked casserole (covered tightly) for up to 3 months. Thaw overnight in the fridge before baking as directed.
Why did my casserole turn out watery?
Watery casseroles usually happen from one of three things: overcooking the chicken before adding sauce, not draining mushrooms properly, or underbaking. Make sure to cook the chicken just until 165°F and let it cool slightly before assembling. Squeeze excess moisture from sliced mushrooms with a paper towel, and always bake until the center reaches 160°F. A 10-minute broil at the end can help crisp up any excess moisture too.
How can I make this dish lower in carbs?
Swap the breadcrumbs for crushed pork rinds or almond flour (use ½ cup for the same volume). For the base, replace ½ cup flour with 2 tablespoons cornstarch mixed with 2 tablespoons flour. The texture will be slightly different but still delicious. You could also use cauliflower rice instead of regular rice if you're making a rice-based version.
