Ingredients for campbell's cream of mushroom chicken casserole
Pantry staples plus a few fresh touches—this casserole comes together faster than you can say golden crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Breast 🍗 | 2 ½ lb | Boneless, skinless, cut into bite-sized pieces |
| Cream of Mushroom Soup 🍲 | 2 cans | Campbell's condensed, 10.5 oz each |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium sharp, freshly shredded |
| French Fried Onions 🧅 | ½ cup | For topping, store-bought or homemade |
| Mushrooms 🍄 | 8 oz | Sliced, cremini or white |
| Yellow Onion 🧅 | 1 whole | Medium, finely chopped |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
The chicken is game-changing here. Buy boneless, skinless breasts—they cook evenly and stay juicy. Costco or Trader Joe's usually have them pre-cut, which saves time. If you're using whole breasts, cut them into small, even pieces so they cook through without drying out. The mushrooms? Cremini or white work perfectly—avoid the pre-sliced kind if you can, since they brown faster. For the onions, yellow or white are ideal, but red adds a nice pop of color if you're feeling fancy.
No Campbell's soup? Homemade cream of mushroom is easy—just sauté mushrooms, onions, and garlic, then blend with cream and a splash of chicken broth. Short on heavy cream? Half-and-half plus a tablespoon of butter works in a pinch. The French fried onions? Store-bought is fine—just check the ingredients list for no weird additives. For the cheese, sharp cheddar is best, but Monterey Jack melts beautifully too. If you're watching carbs, use half the amount of flour and stir in an extra splash of milk.
This casserole reheats like a dream—better the next day, honestly. Store leftovers in an airtight container for up to 4 days. Freezes beautifully too—portion into single servings before freezing for 3 months. Pro tip: Sprinkle a little extra cheese on top before baking if you want that extra crispy crust. Serve with a crisp green salad or warm dinner rolls to soak up every last bit of that creamy goodness.
Why You'll Love This Recipe
- I’ll be real: this recipe stretches my grocery budget and my patience for leftovers. Chicken breast keeps it affordable, the canned soup cuts costs, and one pan means fewer dishes to wash. Plus, the heavy cream and cheese make it feel indulgent—without breaking the bank.
- One-Pot Magic: The second I pull this bubbling, golden casserole from the oven, I know I made the right call—no chopping, no fuss, just dump-and-bake. That creamy mushroom soup base does all the heavy lifting while I toss in pre-cooked chicken, heavy cream, and cheese, then let the oven work its magic.
- Cheesy Crispy Bliss: Between us, the moment those French fried onions hit the top—crunchy, salty, and caramelized—is why I keep making this. The cheddar melts into a velvety blanket around tender chicken, while the onions add that irresistible texture that makes it disappear faster than you can say "seconds, please."
- Weeknight Workhorse: Honestly? This is my go-to when I’ve got soccer practice, homework, and a dog that needs dinner too. It reheats beautifully for lunches, feeds a crowd without stress, and even my picky teenager doesn’t complain—though he will fight me for the last bite of the crispy onion bits.
Step-by-step instructions for creamy mushroom chicken casserole
This cheesy, creamy masterpiece comes together in layers that bake to bubbly perfection.
🍳 Step 1: Sauté the Aromatics for Maximum Flavor
Melt the 0.5 cup butter in a large skillet over medium heat. Add the 1 whole yellow onion and 8 oz sliced mushrooms, cooking for 5-6 minutes until they soften and release their moisture. You'll see the mushrooms shrink slightly—that's when they're ready for the next step.
Add the 3 cloves minced garlic and cook for 30 seconds until fragrant. Here's the thing—don't let the garlic burn. It should smell amazing but not bitter. Transfer this aromatic mixture to a large bowl and set aside. This forms the flavor base for your creamy sauce.
👨🍳 Step 2: Create the Creamy Sauce Foundation
In the same skillet, sprinkle the 2 tbsp all-purpose flour over the melted butter remnants and stir constantly for 1-2 minutes until lightly golden. This creates a roux that will thicken your sauce beautifully. Slowly whisk in the 0.5 cup milk and 0.5 cup heavy cream, stirring until smooth and slightly thickened.
Remove the skillet from heat and stir in 1 can of Campbell's cream of mushroom soup. Then add the sautéed onion and mushroom mixture back to the skillet. Stir in 1 tsp salt and 0.5 tsp black pepper. The sauce should be thick but still pourable—this is your creamy glue that holds everything together.
🥘 Step 3: Combine Chicken and Sauce
Cut the 2.5 lb chicken breast into bite-sized pieces. Add the chicken to the skillet with the sauce and stir gently to coat each piece completely. Let it sit for 2-3 minutes so the chicken absorbs some of that rich flavor. You'll see the chicken start to turn opaque—that's your signal it's absorbing the creamy goodness.
Transfer the chicken mixture to a 9x13-inch baking dish, spreading it evenly. Sprinkle 2 cups shredded cheddar cheese evenly over the top. The cheese should melt into that creamy sauce, creating the perfect cheesy blanket. Real talk: this is where the magic happens—don't skip this layer!
🔥 Step 4: Bake to Bubbly Perfection
Preheat your oven to 375°F. Bake the casserole uncovered for 25-30 minutes until the top is golden brown and bubbly. You'll know it's ready when the edges look crispy and the cheese has formed a delicious crust. If you're worried about burning, tent with foil for the last 5 minutes.
While it bakes, prepare the topping: sprinkle the 0.5 cup French fried onions evenly over the cheese. The onions will get crispy and add that perfect crunchy contrast to the creamy layers below. The moment you see those onions turn golden, your casserole is ready.
⏰ Step 5: Rest and Serve with Confidence
Remove from the oven and let it rest for 5 minutes before serving. This resting period allows the cheese to set slightly and makes it easier to slice. The casserole should be creamy in the center with crispy golden edges—exactly what you're after for that restaurant-quality texture.
Slice into squares and serve immediately. Each bite delivers that perfect combination of tender chicken, creamy mushroom sauce, and melty cheddar. The French fried onions on top add that final crunch that takes this dish from good to amazing. Don't forget to save some for leftovers—they're even better the next day!
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- Poach Chicken First: Skip the raw chicken in the casserole—it’ll turn rubbery and dry. Simmer boneless breasts in salted water for 12-15 minutes until just cooked, then shred. The soup mixture will stay creamy, not watery, and the texture stays tender. (Yes, even if you’re impatient like me.)
- Dry the Cheese: Pat that shredded cheddar with a paper towel before sprinkling it on top. Wet cheese clumps and slides off, leaving you with a sad, uneven crust. A quick rub ensures it melts into a golden, crispy blanket—no one wants a soggy cheese disaster.
- Temper the Cream: Warm the heavy cream with the soup off the heat first—just heat it in a separate bowl until steaming, then mix it in. Cold cream curdles when hit with hot soup, and no one wants lumpy casserole. Stir gently; this isn’t a smoothie.
- Toast the Onions: Spread those French fried onions on a baking sheet and broil for 2-3 minutes before adding them to the top. The heat crisps them up so they don’t turn mushy under the cheese. (Pro move: Do this right after pulling the casserole from the oven—less waiting, more crunch.)
Wine and beer pairings for this campbell's cream of mushroom chicken casserole
Creamy Comfort Wines
This rich, cheesy casserole pairs beautifully with Chardonnay—especially a buttery, oaked version like Kim Crawford Reserve or La Crema. The wine’s vanilla and citrus notes cut through the creaminess while complementing the earthy mushrooms.
For something lighter, try a Sauvignon Blanc with its crisp acidity—Cloudy Bay works wonderfully. 🍷
Malty Beer Balance
A honey wheat beer like Blue Moon or Allagash White brings sweetness that mirrors the casserole’s richness. The hops and floral notes provide a refreshing contrast to the cheesy layers.
For a darker option, an amber ale such as Fat Tire adds a malty depth that stands up to the mushrooms and chicken. 🍺
Unexpected Sparkling Pairing
Don’t overlook sparkling wine—a Prosecco or Cava adds a celebratory touch while cleansing your palate between bites. The bubbles and slight sweetness make the dish feel even more special. I’ve served this casserole at holiday dinners with La Marca Prosecco and it was a hit every time. ✨
Coffee or Tea Finish
End your meal with a dark roast coffee like Peet’s Major Dickason’s Blend to balance the richness. For a caffeine-free option, a spiced chai tea with warm cinnamon notes complements the dish’s cozy flavors. Both pairings help cleanse the palate and leave you feeling satisfied. 💛
Nutrition facts
Frequently asked questions
Can I use rotisserie chicken instead of fresh chicken breast?
Rotisserie chicken works perfectly and saves time. Shred the meat from 2-3 chicken breasts (about 2.5 lbs cooked weight) and use it in place of the fresh chicken. The flavor will be richer, and you'll still get that tender texture. Just drain any excess fat or seasoning packets before mixing with the sauce.
How do I make this casserole gluten-free?
Replace the 2 tbsp all-purpose flour with 2 tbsp gluten-free flour blend or cornstarch. Also check your Campbell's soup label—some varieties contain wheat. For extra insurance, use a gluten-free cream of mushroom soup alternative. The texture will still be creamy, just slightly thicker from the cornstarch.
Can I make this ahead of time for a dinner party?
Yes! Assemble the casserole in a baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. When ready, bake at 375°F for 30-35 minutes (5 minutes longer than fresh). The flavors actually deepen overnight, making it perfect for stress-free entertaining. Just add 5 extra minutes to the baking time.
What's the best way to reheat leftovers?
Transfer individual portions to microwave-safe dishes and cover loosely with a damp paper towel. Reheat on high for 2-3 minutes until steaming hot. For oven reheating, cover with foil and bake at 350°F for 15-20 minutes. The oven method preserves the crispy top better. Leftovers keep well for 4 days in the fridge.
Why did my casserole turn out watery?
This usually happens when the sauce wasn't thickened enough. Next time, cook the roux (butter + flour) for 2-3 minutes until golden brown before adding liquids. Also ensure you're using full-fat dairy products—they create a richer, thicker sauce. If it's still too thin, sprinkle extra cheese on top and bake uncovered for 5 more minutes.
