Ingredients for campbell's cream of mushroom chicken casserole
Sixteen ingredients transform nostalgic comfort into professional-level casserole perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Chicken Breast 🍗 | 2 lb | Boneless, skinless, cut into bite-sized pieces |
| Egg Noodles 🍝 | 2 cups | Uncooked, broken in half |
| Fresh White Mushrooms 🍄 | 1 ½ cups | Sliced, stems removed |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for topping |
| Saltine Crackers 🍞 | 2 cups | Crushed into fine crumbs |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, for topping |
| Garlic Cloves 🧄 | 3 cloves | Minced for flavor base |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for heat |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme leaves |
| Onion Powder 🧅 | ½ tsp | For depth of flavor |
The Campbell's soup is the foundation—always use the condensed version for the right texture. For mushrooms, farmers market varieties like cremini or white button work best, but avoid pre-sliced (they brown too fast). The chicken should be evenly sized pieces—cut larger breasts into 1-inch cubes. Egg noodles are ideal here; they hold up better than other pasta shapes. Store-brand noodles work fine, but avoid overcooking them before adding to the casserole. For the topping, Ritz or Triscuits can replace saltines if needed—just crush them extra fine.
No Campbell's soup? Homemade mushroom sauce made with cream, butter, and fresh mushrooms works beautifully. Short on chicken? Rotisserie chicken shredded into bite-sized pieces is a great shortcut. The flour is key for thickening—all-purpose works best—but if you're gluten-free, use cornstarch instead. For the topping, butter and Parmesan are non-negotiable—they create that golden, crispy finish. If you can't find saltines, crushed potato chips add a fun twist (try kettle-cooked for extra crunch).
This casserole reheats beautifully—cover with foil for 10 minutes after baking to keep the topping crispy. Store leftovers in an airtight container for up to 5 days. The topping can be prepped ahead and kept in the fridge until ready to bake. For parties, double the topping ingredients—it disappears fast. Freeze portions for up to 3 months; thaw overnight in the fridge before reheating.

Step-by-step instructions for cream of mushroom chicken casserole
Here's the straightforward method for a creamy, comforting casserole with crispy cracker topping.
Prepare the Chicken and Sauté Aromatics
Cut the 2 lb chicken breast into bite-sized pieces, about 1-inch cubes. In a large skillet, melt 2 tablespoons unsalted butter over medium heat. Add the 3 cloves minced garlic cloves and cook for 30 seconds until fragrant. Add the chicken pieces and cook for 5-6 minutes until lightly browned on all sides and cooked through.
Remove the chicken from the skillet and set aside. In the same skillet, add the 1.5 cups sliced fresh white mushrooms and cook for 4-5 minutes until softened. Sprinkle with 0.5 tsp dried thyme and 0.5 tsp onion powder, stirring to combine. Remove from heat and set aside with the chicken.
Make the Creamy Sauce
In a large bowl, whisk together the 2 cans Campbell's Cream of Mushroom Soup, 1 cup milk, and 2 tablespoons all-purpose flour until smooth. Pour this mixture into a 9x13-inch baking dish. Stir in the cooked chicken and mushrooms, spreading them evenly throughout the sauce. Sprinkle with 0.5 tsp black pepper and mix gently.
Add the 2 cups egg noodles, breaking them in half if needed, and stir until they're fully coated in the mixture. The noodles will absorb the sauce as they cook, so don't worry if they look dry at this stage.
Assemble and Bake the Casserole
Preheat your oven to 375°F. In a small bowl, combine the 2 cups crushed Saltine crackers and 0.5 cup freshly grated Parmesan cheese. Sprinkle this mixture evenly over the top of the casserole, pressing down lightly with the back of a spoon to create an even, crispy layer.
Dot the top with the remaining 0.5 cup unsalted butter, cutting it into small cubes and distributing them evenly. Bake uncovered for 30-35 minutes until the cracker topping is golden brown and the casserole bubbles around the edges. The center should be hot and creamy when tested with a fork.
Rest and Serve
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the cracker topping to crisp up further and the layers to set properly. The creamy sauce should coat the noodles and chicken perfectly, with a crispy, golden-brown cracker crust on top.
Serve warm with a side salad or steamed vegetables. The casserole reheats beautifully, so leftovers taste just as good the next day. Store any unused portions in an airtight container in the refrigerator for up to 3 days.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- Sear Chicken First: Tossing raw chicken straight into the soup? Skip it. After poaching or baking the chicken, sear the slices in a hot pan for 30 seconds per side—just until golden. The extra step adds depth of flavor that turns this casserole from "meh" to "oh, that’s better." (Yes, even if you’re impatient like me.)
- Sauté Mushrooms Dry: I learned this the hard way—damp mushrooms release water that turns your sauce into soup. Pat them very dry with a paper towel, then sauté in a dry pan over medium-high heat for 5 minutes until they’re deeply browned. The texture change makes all the difference, and you’ll taste it in every bite.
- Don’t Boil Noodles: Cook egg noodles just until al dente (about 1 minute less than package instructions), then drain and rinse with cold water. Tossing them into the hot casserole later keeps them from turning mushy—no one wants a sad, gluey texture in their cream of mushroom magic.
- Stir in Cheese Late: If you’re adding cheese (because you should), fold it in right before baking, not during assembly. The heat will melt it perfectly into the soup, creating a creamy, gooey layer on top instead of a clumpy mess. (Pro move: shred your own cheddar—pre-shredded stuff has anti-caking agents that burn.)
Storing and reheating this campbell's cream of mushroom chicken casserole
Refrigerator Storage
Let your casserole cool completely before storing—about 2 hours—to prevent condensation that can make the cracker topping soggy. Transfer to an airtight container (I love Glasslock containers for this) and refrigerate for up to 5 days.
The flavors actually deepen overnight, so leftovers often taste even better reheated. Just make sure to cover it tightly to keep that crispy topping intact. 🥫
Freezer Prep Tips
For longer storage, freeze portions in single-serving sizes (about 1.5 cups per container) for easy reheating. Use quart-sized freezer bags or silicone molds—they prevent freezer burn better than rigid containers.
Label with the date and freeze for up to 3 months. Thaw overnight in the fridge before reheating for best texture. 🧊
Oven Reheating
Preheat your oven to 350°F and cover the casserole loosely with foil (leave a small vent for steam). Bake for 20-25 minutes until heated through. For extra crispiness, broil for 2-3 minutes at the end—just watch it like a hawk to avoid burning the topping.
The creamy sauce will thicken slightly, so a splash of milk or broth can restore its velvety texture. 🔥
Microwave Method
If you're short on time, use microwave-safe dishware and cover with a damp paper towel (this traps steam and prevents drying). Heat on medium power (50%) for 3-4 minutes, stir, then continue in 30-second intervals until reaching 165°F.
Add a splash of milk if it looks dry—this casserole reheats best when creamy, not rubbery. 💡
Reviving the Topping
If the cracker topping loses its crunch after reheating, pop it back under the broiler for 1-2 minutes until golden. For extra crispiness, sprinkle with extra Parmesan and broil until bubbly. I also like toasting new cracker crumbs on top right before serving—it adds that fresh-from-the-oven crunch everyone loves. 🧀
Make-Ahead Topping
Prep the cracker topping ahead and store it in the fridge until ready to bake. Mix the crushed crackers, Parmesan, and butter cubes in a bowl and keep it covered.
When you're ready to bake, simply sprinkle it on top—no need to thaw. This shortcut saves time on busy weeknights and keeps the topping from getting soggy during prep. ⏰

Frequently asked questions
Can I use rotisserie chicken instead of fresh chicken breast?
Rotisserie chicken is a fantastic shortcut. Shred or chop 2 cups of cooked chicken into bite-sized pieces to replace the 2 lb fresh chicken breast. Just make sure to drain it well to avoid making the casserole soggy. The flavor will be richer and more complex, too!
How do I keep the cracker topping from getting soggy?
Press the cracker-Parmesan mixture firmly onto the casserole before baking, and avoid overfilling the baking dish. For extra insurance, bake at 375°F for 30 minutes before adding the topping, then bake another 15 minutes to set it properly. A quick broil for 2 minutes at the end also helps restore crispiness.
What can I substitute if I don't have Saltine crackers?
Try crushed Ritz crackers, Triscuits, or even potato chips for a different texture. For a cheesy topping, use crushed cornflakes mixed with Parmesan. Just crush them extra fine—coarse crumbs won't get as crispy. Kettle-cooked potato chips add a fun, salty crunch that kids love!
Can I make this casserole ahead and freeze it?
Yes! Assemble the casserole (without the topping) and refrigerate for 24 hours to let flavors meld. For freezing, cover tightly with foil and plastic wrap, then freeze for up to 3 months. Thaw overnight in the fridge, add the topping, and bake as directed. The topping should be added fresh to ensure crispiness.
Why did my casserole turn out watery?
Watery texture usually means the pasta absorbed too much sauce. Next time, break the noodles in half before adding them to the baking dish, and stir them into the sauce after it's in the dish. Also, ensure your baking dish isn't too large—this recipe works best in a 9x13-inch dish. If needed, bake uncovered for 5-10 extra minutes to thicken the sauce.
