Ingredients for campbell's cream of chicken casserole

Pantry staples meet restaurant-quality technique for this timeless comfort dish.

The Campbell's Condensed Cream of Chicken Soup serves as the flavor foundation—always use the full can for optimal richness. For the mushrooms, fresh white varieties yield the best texture, though cremini works in a pinch. The yellow onion should be bright white with no sprouting, and the celery needs to be crisp with no brown spots. Trader Joe's and Whole Foods carry the best quality for these staples, but standard grocery stores suffice. The garlic powder should be freshly ground—pre-ground loses potency quickly. For the breadcrumbs, Panko-style provides superior texture, but standard breadcrumbs work if you're in a hurry.

No Campbell's Condensed Cream of Chicken Soup? Homemade chicken velouté works beautifully—simmer chicken stock with roux and cream. Substitute cremini mushrooms for white if needed, though they'll be slightly more earthy. For the celery crown, green onions or scallions can replace half the celery for a milder flavor. The cornflakes should be lightly crushed by hand to avoid powdering. If you prefer a cheesy version, add 1 cup shredded cheddar to the topping mix. The butter for the celery crown must be unsalted to control seasoning balance—salted butter will over-salt the delicate celery flavor.

This casserole reheats beautifully—cover with foil and bake at 350°F for 20 minutes. The celery crown stays crisp for 3-4 days if stored properly in an airtight container. For make-ahead convenience, assemble completely (without baking) and refrigerate for up to 24 hours before baking. The sauce thickens as it cools, so add 1-2 tbsp milk if it seems too thick after chilling. Garnish with fresh parsley just before serving to maintain vibrant color.

Step-by-step instructions for Campbell's cream of chicken casserole

Here's the method—layered technique ensures velvety sauce and crispy celery crowns every time.

Begin by slicing the 4 whole celery stalks into thin rounds using a mandoline or sharp knife—aim for ¼-inch thickness. Set aside. In a large skillet, melt the 2 tablespoons unsalted butter over medium heat. Add the 1 whole yellow onion, finely chopped, and cook for 5 minutes until translucent.

Stir in the 1.5 cups fresh white mushrooms, sliced thin, and cook for another 5 minutes until they release their moisture and begin to soften. Sprinkle in the 1 teaspoon garlic powder, 0.5 teaspoon salt, and 0.25 teaspoon black pepper, stirring to combine. Remove from heat and set aside—this aromatic base forms the flavor foundation of the casserole.

In a separate bowl, whisk together the 2 cans Campbell's Condensed Cream of Chicken Soup and 1.5 cups whole milk until smooth. Gradually whisk in the 0.5 cup all-purpose flour, ensuring no lumps remain. This mixture should be thick but pourable—like heavy cream consistency.

Return the skillet with sautéed aromatics to medium-low heat and carefully pour in the soup mixture. Stir constantly for 3-4 minutes until the sauce begins to thicken and coat the back of a spoon. The goal is a velvety, clingy texture—this ensures the casserole holds its shape when baked. Taste and adjust seasoning if needed.

Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish to prevent sticking. Spread half of the 1.5 cups plain breadcrumbs evenly across the bottom, creating a thin, even layer. This forms the crispy base that prevents sogginess.

Pour the thickened cream mixture over the breadcrumbs, spreading it evenly with a spatula. Arrange half of the celery rounds in a single layer on top, slightly overlapping if necessary. Repeat with the remaining breadcrumbs and celery, finishing with a final layer of celery crowns on top. This layered approach guarantees each bite delivers both crispy and creamy textures.

Sprinkle the 0.5 cup crushed cornflakes evenly over the top layer of celery. This creates the signature crunch—press down gently to ensure they adhere. Bake uncovered for 25-30 minutes until the top is golden brown and the edges bubble slightly.

Here's the key: The cornflake topping should be crispy while the celery remains tender. If the top browns too quickly, tent loosely with foil for the last 5 minutes of baking. Remove from the oven and let rest for 10 minutes before serving—this allows the layers to set and prevents a runny casserole.

Before serving, sprinkle the 0.25 cup fresh parsley evenly over the top for a pop of color and freshness. The parsley not only enhances presentation but also balances the richness of the cream sauce. Serve immediately with crusty bread or a simple green salad to complement the hearty flavors.

Each bite should deliver the contrast of crispy celery crowns against the velvety mushroom sauce. The breadcrumb base prevents sogginess, while the cornflake topping adds satisfying texture. This method ensures restaurant-quality results with minimal effort—perfect for family dinners or meal prep.

Essential equipment for great campbell's cream of chicken casserole

Baking Dish Essentials

For this casserole, a 9x13-inch baking dish is non-negotiable—it provides the perfect surface area for even baking and crispy edges. I recommend using a Ceramic CorningWare dish or a heavy-duty stainless steel pan for superior heat distribution.

Avoid glass dishes that aren't oven-safe or aluminum pans that can react with acidic ingredients. If you don't have a 9x13-inch dish, a 9-inch round dish works but may require slightly longer baking time. 🔥

Mandoline for Celery

A mandoline slicer is my secret weapon for achieving those perfect, even celery rounds. The OXO Good Grips Mandoline is my go-to—it's safe, easy to use, and produces slices that are consistently ¼-inch thick.

If you don't own one, a sharp chef's knife works, but it takes more practice to achieve uniform slices. Pro tip: Wrap the celery tightly in a kitchen towel before slicing to prevent the mandoline blade from slipping. 🥬

Skillet for Aromatics

Use a 10-inch cast iron skillet or stainless steel sauté pan for sautéing the onions and mushrooms. Cast iron retains heat beautifully and creates a natural fond that adds depth to the flavor. If you don't have cast iron, a heavy-bottomed stainless steel pan works just as well.

Avoid nonstick pans for this step—they don't provide enough heat control for proper browning. I like to use my Lodge cast iron skillet for this exact reason. 🍄

Mixing Bowls and Whisk

For the sauce mixture, a medium-sized mixing bowl (at least 3-quart capacity) is ideal. I prefer stainless steel bowls because they're durable and easy to clean. Pair it with a balloon whisk—the OXO Good Grips Balloon Whisk—to ensure the Campbell's soup and milk blend smoothly without lumps.

A whisk with silicon-coated wires prevents scratching your nonstick bowls if you ever use them. 🥛

Measuring Tools

Precision matters when measuring ingredients like the 0.5 cup flour and 1.5 cups breadcrumbs. Use a stainless steel measuring cup set for dry ingredients and a liquid measuring cup for the milk. I keep a Ninja Foodi Precision Measuring Cups Set handy—it's accurate and easy to read.

For the 2 tablespoons butter, a stainless steel measuring spoon ensures you get the exact amount needed for the celery crown. Never eyeball measurements in this recipe! 🧈

Optional: Food Processor

If you prefer to crush your cornflakes uniformly, a mini food processor like the Cuisinart Mini-Prep Plus makes quick work of it. Simply pulse the cornflakes in 2-second bursts until they're lightly crushed but not powdery.

This ensures an even, crispy topping. If you don't have one, use a rolling pin or heavy pan to gently crush them in a plastic bag. 🍞
