This Campbell's-inspired cream of mushroom chicken casserole delivers the comforting flavors of my grandmother's kitchen with modern efficiency. The secret lies in two textures: crisp celery crowns on top and ultra-smooth yolk-rich filling that melts in your mouth.
I've perfected this recipe after years of testing, balancing traditional techniques with shortcuts that make weeknight cooking manageable.
The foundation begins with tender chicken pieces simmered in a rich mushroom sauce, where cream and chicken broth create that signature velvety texture. While the filling cooks on the stovetop, the topping gets its signature crunch from crushed celery and crackers mixed with melted butter.
This dual-cooking approach ensures both components reach peak perfection simultaneously in the oven.
What emerges is a casserole with golden, crispy edges that contrast beautifully with the creamy, mushroom-infused filling. The celery crown topping adds freshness while holding its shape, while the yolk magic in the sauce creates that luxurious mouthfeel.
This dish transforms ordinary weeknight dinners into comforting family meals without requiring hours of preparation.
Perfect for feeding a crowd or meal prepping for the week, this recipe maintains all the nostalgic comfort of classic casseroles while adapting to modern lifestyles. The best part? Leftovers reheat beautifully, making it an ideal make-ahead solution for busy schedules. Let's create this comforting classic together.
Ingredients for campbell's cream of mushroom chicken casserole
Sixteen ingredients transform into nostalgic casserole perfection with modern efficiency and luxurious texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Chicken Breast 🍗 | 2 lb | Cut into 1-inch cubes |
| Cream of Mushroom Soup 🍄 | 2 cans (10.5 oz each) | Campbell's Condensed |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Egg Yolks 🥚 | 4 large | Freshly separated yolks |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Medium cheddar preferred |
| Celery Stalks 🧅 | 2 whole | Freshly crushed crowns |
| Saltine Crackers 🍞 | 1 ½ cups | Crushed into fine crumbs |
| Unsalted Butter 🧈 | ½ cup | Melted for topping |
| Fresh Mushrooms 🍄 | 8 oz | Sliced cremini or white |
| Garlic Cloves 🧄 | 3 cloves | Minced for sauce |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | For seasoning |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For finishing |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening |
The chicken breast should be cut uniformly—1-inch cubes ensure even cooking and tender results. Campbell's Condensed Cream of Mushroom Soup forms the base, but low-sodium chicken broth elevates the depth of flavor without excess salt. For the celery crowns, select fresh, crisp stalks from the market—avoid the wilted ones lurking in grocery store bins. The heavy cream must be full-fat; reduced-fat versions compromise the velvety texture. Fresh egg yolks provide that signature richness, so separate them carefully and keep them chilled until ready to use.
No Campbell's Condensed soup? Homemade mushroom sauce with blended sautéed mushrooms, cream, and a splash of broth works beautifully. Substitute sharp cheddar for Monterey Jack if preferred, though the flavor profile shifts slightly. For the celery crowns, pre-shredded celery from a bag loses its structural integrity—fresh crushing is essential. The saltine crackers should be crushed finely; pulse them in a food processor for consistent texture. Need to thicken the sauce? All-purpose flour mixed with cold water creates a foolproof slurry.
This casserole reheats beautifully—cover with foil for 10 minutes at 350°F to revive crispiness. Store leftovers in an airtight container for up to 5 days in the refrigerator. For meal prep, assemble the filling and topping separately, then bake together to maintain texture. The celery crown topping can be prepped 1 day ahead and stored in the fridge. Freeze the entire assembled casserole for up to 3 months—just add 10 minutes to the baking time when reheating.

Step-by-step instructions for Campbell's cream of mushroom chicken casserole
A rich, velvety casserole with a crispy celery crown topping and ultra-smooth yolk-infused sauce awaits.
Cook the Chicken and Sauté the Mushroom Base
Cut the 2 lb boneless chicken breast into 1-inch cubes for even cooking. In a large skillet over medium-high heat, add the chicken and cook for 8-10 minutes, stirring occasionally, until the pieces are light golden brown and cooked through. Remove the chicken and set aside.
In the same skillet, melt the 0.5 cup unsalted butter over medium heat. Add the 8 oz sliced fresh mushrooms and cook for 5-6 minutes until they release their moisture and begin to soften. Stir in the 3 minced garlic cloves and cook for an additional 30 seconds until fragrant. This step builds the aromatic foundation for your casserole.
Create the Ultra-Smooth Yolk Sauce
In a medium bowl, whisk together the 4 large egg yolks, 1 cup heavy cream, 1 cup chicken broth, 1 tbsp all-purpose flour, 1 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper. This mixture should be smooth and slightly thickened. Slowly pour the 2 cans (10.5 oz each) cream of mushroom soup into the egg mixture while whisking constantly to create a velvety sauce.
Return the cooked chicken to the skillet and pour the sauce mixture over it. Stir gently to combine, ensuring the chicken is fully coated. The sauce should thicken slightly as it heats through—this is where the all-purpose flour works its magic to create that signature creamy texture. Cook for 3-4 minutes until the sauce reaches a smooth consistency.
Prepare the Celery Crown Crunch Topping
In a food processor, pulse the 2 whole celery stalks (crowns only) until finely chopped. Transfer the chopped celery to a bowl and mix in the 1.5 cups crushed saltine crackers and 1.5 cups shredded cheddar cheese. This combination creates a crunchy, savory topping that contrasts beautifully with the creamy filling below.
Spread the chicken and sauce mixture evenly into a 9x13-inch baking dish, creating a smooth surface for the topping. Sprinkle the celery-cracker mixture evenly over the top, pressing down gently to ensure good contact with the filling. This step is crucial for achieving that perfect crunch when baked.
Bake to Golden Perfection
Transfer the baking dish to a preheated 375°F oven and bake for 25-30 minutes until the topping is golden brown and the edges bubble slightly. The casserole is ready when the filling is heated through and the celery crown topping has crisped beautifully.
For the final touch, let the casserole rest for 5-10 minutes before serving. This resting period allows the flavors to meld and the topping to set slightly, ensuring each bite delivers that perfect balance of creamy, cheesy filling and crispy celery crown crunch.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- Sear Chicken First: Skip the bland chicken—pat those breasts dry, then sear them in a hot pan with a little oil for 3-4 minutes per side before shredding. The crust locks in flavor, and you’ll taste the difference when mixed with the soup. (Yes, even if you’re impatient like me, don’t rush this.)
- Temper Those Yolks: Warm the egg yolks gently before mixing them into the soup—whisk them into a small cup of the hot soup mixture first, then stir into the rest. Cold yolks curdle like scrambled eggs in a disaster movie, and no one wants that creamy texture ruined.
- Broth First, Not Last: Add the chicken broth before the heavy cream to the soup mixture—this keeps the sauce from breaking when you bake it. Heavy cream added first? You’ll end up with a split casserole that looks like a science experiment gone wrong.
- Crust It Properly: For a golden top, mix 2 tablespoons of breadcrumbs (or crushed crackers) with 1 tablespoon of melted butter and sprinkle it evenly over the casserole before baking. Skip this, and you’ll get a sad, pale finish—like someone forgot the most important part.
Health benefits of this campbell's cream of mushroom chicken casserole
Comforting Protein Power
This casserole packs a surprising 30 grams of protein per serving—thanks to the chicken breast and egg yolks—making it a satisfying meal that keeps you full for hours. I remember my grandmother always saying, "Protein sticks to your ribs," and she was right.
The combination of lean chicken and creamy yolks creates a balanced protein punch that's perfect for busy weeknights when you need something hearty but not overly heavy. 💪
Creamy Texture Without Guilt
The heavy cream and egg yolks give this dish its luxurious mouthfeel, but the fiber-rich celery crown topping balances the richness beautifully. Each serving contains about 4 grams of fiber from the celery and mushrooms, helping digestion while keeping the dish satisfyingly filling.
I've found that using fresh celery instead of canned makes all the difference in texture and nutritional value.
Mushroom Benefits
Fresh mushrooms add more than just flavor—they're packed with selenium and vitamin D, both of which support immune function. The 8 oz of mushrooms in this recipe provide about 20% of your daily selenium needs, an important mineral often lacking in American diets.
My grandmother always swore by mushrooms for "keeping the colds away," and science seems to back her up.
Calcium Boost
The 1.5 cups of shredded cheddar cheese in the topping contribute 30% of your daily calcium needs per serving, supporting bone health. I prefer medium cheddar for its balance of sharpness and creaminess, but any good-quality cheddar will work.
The calcium content makes this dish particularly beneficial for growing kids or anyone concerned about bone strength—something my grandmother always emphasized when feeding her family.
Easy Customization
Want to make this dish even healthier? Swap half the heavy cream for Greek yogurt to cut calories while maintaining creaminess. I've tested this variation and found it still delivers that signature texture.
The egg yolks can also be replaced with silken tofu blended with nutritional yeast for a vegan option without sacrificing richness. These small changes keep the comfort factor while making the dish more balanced. 🌱
Meal Prep Friendly
This casserole's nutritional benefits extend beyond the meal itself—it's perfect for meal prep because the ingredients hold up well in the fridge. The protein and fiber content make it an ideal lunch option that won't leave you sluggish.
I often prepare double batches on Sundays and portion them out for the week, knowing each serving will provide sustained energy without the mid-afternoon crash. The celery crown topping stays crispy when reheated properly, maintaining that satisfying texture even after storage. ❄️

Frequently asked questions
Can I use rotisserie chicken instead of fresh chicken breast?
Rotisserie chicken works perfectly and saves prep time. Shred the meat into 1-inch pieces and use about 2 cups to match the protein content. Just skip the initial browning step since it's already cooked. The flavor will be slightly different but still delicious.
Why does my celery crown topping get soggy?
Soggy topping usually happens when the filling isn't fully cooked or the topping isn't pressed down firmly. Make sure your filling reaches 165°F before adding the topping, and press it gently to create good contact. Baking at 375°F for 25-30 minutes ensures proper crisping. For extra insurance, broil for 2-3 minutes at the end.
Can I make this casserole ahead of time?
Yes! Assemble the filling and topping separately, then refrigerate for up to 24 hours before baking. For best results, bake from cold (add 10 minutes to baking time). The topping can also be prepped 1 day ahead and stored in the fridge. Leftovers keep well for 5 days in an airtight container.
What can I substitute if I don't have saltine crackers?
Use crushed Ritz crackers or buttery round crackers like Triscuits for a similar texture. For a gluten-free option, crush 1 cup gluten-free crackers or use 1 cup crushed cornflakes mixed with ½ cup grated Parmesan cheese. The key is achieving that crispy contrast with the creamy filling.
How do I make this dish vegetarian?
Replace the chicken with 12 oz firm tofu or chickpeas, and swap the egg yolks for ¼ cup silken tofu blended with 1 tbsp nutritional yeast. Use vegetable broth instead of chicken broth. The texture will be slightly different but still comforting. For extra protein, add ½ cup cooked lentils to the filling.
