Ingredients for campbell's cream of mushroom chicken casserole
Six ingredients transform Campbell's classic into a restaurant-worthy casserole with crisp celery crowns and hidden veggie magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Boneless Chicken Breast 🍗 | 2 lb | Cut into 1-inch cubes |
| Celery Stalks 🧅 | 4 whole | Large, for crowns only |
| Fresh Mushrooms 🍄 | 8 oz | Sliced, cremini or white |
| Cauliflower Florets 🥬 | 2 cups | Fresh or frozen, chopped |
| Carrots 🥕 | 1 cup | Baby or julienned |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, aged 6+ months |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for topping |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns |
| All-Purpose Flour 🌾 | 2 tbsp | For celery crown coating |
| Grated Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for garnish |
The Campbell's cream of mushroom soup is your flavor foundation—don't skimp on quality here. Store-bought cans work fine, but if you're feeling fancy, make a quick roux with butter, flour, and chicken stock for a silkier texture. The chicken breast should be cut into even cubes (about 1-inch) for consistent cooking. Costco or Trader Joe's usually have pre-cut chicken at great prices, saving you chopping time. For the celery crowns, look for thick, pale stalks—they'll yield the most dramatic crunch when baked separately. Fresh mushrooms add depth, but canned mushrooms work in a pinch if you're short on time.
No heavy cream? Half-and-half or whole milk will work, though the texture will be slightly lighter. Sharp cheddar is non-negotiable for that tangy bite—Cabot or Tillamook are my go-tos, but any aged cheddar will do. The cauliflower and carrots are the hidden veggie stars—frozen works perfectly if fresh isn't available, just thaw and drain well. For the celery crowns, flour them lightly before baking to ensure crispiness. No Parmesan? Pecorino Romano adds a similar umami punch. The garlic can be pre-minced from the jar (like Trader Joe's brand) if you're in a hurry, but fresh is always better.
This casserole reheats like a dream—cover with foil and bake at 350°F for 20-25 minutes to revive that creamy texture. Portion into individual baking dishes before freezing for easy single servings. The celery crowns stay crisp for up to 2 days if stored separately in an airtight container. For extra richness, sprinkle a pinch of smoked paprika over the top before baking. Leftovers? Double the batch—this is the kind of dish that disappears fast!

Step-by-step instructions for creamy celery crown chicken casserole
Here's how to transform humble pantry staples into a showstopping casserole with irresistible texture contrasts.
Prep the Celery Crowns and Chicken
First, cut the 4 whole celery stalks lengthwise into thin strips about ¼-inch thick, keeping them attached at the base to form crowns. This creates those iconic crispy tops we all love. While you're working, cut the 2 lb boneless chicken breast into 1-inch cubes—uniform size ensures even cooking.
In a separate bowl, whisk together 2 tbsp all-purpose flour, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper. Toss the chicken cubes in this seasoned flour until evenly coated. This coating creates a golden crust that locks in moisture during baking.
Build the Hidden Veggie Layer
Heat 0.5 cup unsalted butter in a large skillet 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. Add the 4 minced garlic cloves and cook for 30 seconds until fragrant.
Transfer the mushrooms to a large mixing bowl. Add the 2 cups cauliflower florets, 1 cup carrots, and the cooked chicken. Stir in 2 cans Campbell's Cream of Mushroom Soup and 1 cup heavy cream. Mix well to combine all ingredients thoroughly. This layer forms the creamy, flavorful base of your casserole.
Assemble and Bake to Perfection
Preheat your oven to 375°F. Grease a 9x13-inch baking dish with butter or line it with parchment paper for easy removal. Pour the chicken and vegetable mixture into the baking dish, spreading it evenly. Sprinkle 2 cups sharp cheddar cheese and 0.25 cup grated parmesan cheese over the top.
Carefully place the celery crowns on top, arranging them in a circular pattern to create that classic presentation. Drizzle any remaining heavy cream from the bowl over the top for extra richness. Bake uncovered for 30 minutes until the edges begin to bubble and the cheese starts to melt.
Finish with Crispy Topping
Remove the casserole from the oven and sprinkle the 0.5 cup cold cubed unsalted butter evenly over the top. Return it to the oven and bake for an additional 10-15 minutes until the butter melts and the celery crowns turn a beautiful golden brown. The butter creates that irresistible crispy topping we can't resist.
Let the casserole rest for 5-10 minutes before serving. This resting time allows the flavors to meld together and makes it easier to slice. Serve warm with a side of garlic bread or a fresh green salad for a complete meal that will impress everyone at the table.
Pro Tips For Making Campbell'S Cream Of Mushroom Chicken Casserole
- SEAR CHICKEN FIRST: I learned this the hard way—skipping the sear leaves you with bland, rubbery chicken in that creamy soup. Hit the chicken breasts with a hot pan and 2 tablespoons of oil until they’re golden on both sides (about 4-5 minutes per side). The crust adds flavor the soup alone can’t match, and it stays juicy when baked.
- CHOP MUSHROOMS SMALL: Big mushroom chunks turn mushy in the oven, but tiny dice blend right into the sauce. Aim for ¼-inch pieces—no need to overthink it, just quick chops with a sharp knife. This keeps texture consistent and makes the dish look (and taste) more polished.
- SALT THE SOUP: Campbell’s soup is already salty, but the chicken and veggies need balancing. Stir in an extra ½ teaspoon of salt when you mix the soup with milk (or broth), then adjust after tasting. I know, I know—it seems obvious, but I’ve ruined casseroles by skipping this step.
- BAKE COVERED THEN UNCOVERED: Start with the foil on to melt the cheese and thicken the sauce (20 minutes), then uncover for the last 10 minutes. This prevents a watery top layer and gives the cauliflower a chance to crisp slightly—trust me, it makes a real difference. Just don’t skip the foil entirely, or you’ll end up with a sad, soupy mess.
Regional styles of these flavors
Midwest Comfort Twist
This version takes the classic casserole and gives it a hearty Midwest touch by swapping the celery crowns for crispy fried onion rings—a nod to my grandmother's way of using pantry staples.
She'd fry up 1 cup sliced yellow onions in ½ cup vegetable oil until golden, then sprinkle them over the top before baking. The onions add a sweet crunch that pairs perfectly with the creamy mushroom sauce.
For extra flavor, I like to toss the onions in 1 tsp smoked paprika and ½ tsp garlic powder before frying. 🌶️
Southern Potato Layer
In the South, this casserole often gets a thick layer of diced potatoes at the bottom for extra heartiness. Use 2 cups diced Yukon Gold potatoes, parboiled for 5 minutes until just tender, then drained well. Spread them in the baking dish before adding the chicken mixture.
The potatoes soak up the creamy sauce beautifully while adding a satisfying texture. For a true Southern touch, top with crumbled bacon instead of celery crowns—it adds smoky depth that everyone will love.
New England Clam Sauce
Up north, this casserole gets a coastal twist by replacing the cream of mushroom soup with a clam sauce—a nod to New England's seafood traditions. Sauté 1 cup chopped clams (fresh or canned) with 2 tbsp butter, 2 tbsp flour, and 1 cup chicken broth until thickened.
Stir in 1 can cream of mushroom soup to keep the familiar flavor while adding briny richness. The celery crowns stay, but the sauce becomes a creamy, slightly salty masterpiece that feels like a seafood feast. 🍲
Texas BBQ Chicken
For a Texan take, swap the chicken breast for shredded rotisserie chicken and mix in ½ cup BBQ sauce (like Sweet Baby Ray's) with the cream of mushroom soup. Top with crushed tortilla chips instead of celery crowns for a crispy, smoky crunch.
Add diced jalapeños and pickled red onions for a spicy kick. This version feels like a cross between a casserole and a BBQ dip—perfect for game day or a casual family dinner. 🌶️
Pacific Northwest Forest Foraging
In the Pacific Northwest, foragers often replace mushrooms with wild chanterelles or morels for a earthier flavor. If you can't find wild mushrooms, shiitake mushrooms work beautifully. Add 1 tbsp fresh thyme and 1 tsp dried rosemary to the sauce for a forest-inspired aroma.
Top with toasted hazelnuts instead of celery crowns for a nutty crunch that complements the rich, umami flavors of the region. 🌿

Frequently asked questions
Can I make this casserole ahead of time?
Assemble the casserole in your baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. When ready to bake, add 10-15 extra minutes to the cooking time. For freezing, assemble completely (including celery crowns), cover with foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking.
Why do the celery crowns turn soggy?
This happens when they're baked directly on the casserole. The secret is baking them separately on a parchment-lined tray at 400°F for 8-10 minutes before adding to the top. For extra crispiness, sprinkle with 1 tsp cornstarch before baking. Add them to the casserole just before serving to maintain that perfect crunch.
Can I substitute Campbell's soup with homemade?
Yes! For a richer version, make a quick roux with ½ cup butter, ½ cup flour, and 2 cups chicken stock. Add 1 cup sliced mushrooms and 2 minced garlic cloves, simmering for 10 minutes until thickened. This homemade version has deeper flavor but requires more prep time. The texture will be silkier than canned soup.
What's the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 20-25 minutes until heated through. For crispy celery crowns, place them on a separate baking sheet and reheat at 400°F for 3-4 minutes before serving. Microwaving works in a pinch (2-3 minutes), but the texture suffers. The creamy sauce reheats best when gently warmed.
Can I make this vegetarian?
Swap the chicken for 1 lb extra-firm tofu (pressed and cubed) or 12 oz chickpeas (rinsed and drained). For extra protein, add 1 cup cooked lentils to the veggie mixture. The flavor remains rich and satisfying, though the texture will be slightly different. Use ½ cup nutritional yeast for a cheesy flavor if omitting dairy cheese.
