Ingredients for campbell's potato casserole
Creamy spuds meet golden crust—this classic casserole delivers comfort in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Peeled and cubed evenly |
| Campbell's Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Heavy Cream 🥛 | 1 cup | Full-fat for optimal creaminess |
| Shredded Cheddar Cheese 🧀 | 2 cups | Sharp variety preferred |
| Cornmeal 🌽 | 1 cup | Fine grind for smooth texture |
| All-Purpose Flour 🌾 | ½ cup | For crispy topping blend |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for flavor |
| Garlic Powder 🧄 | 1 tsp | For subtle depth |
| Onion Powder 🧅 | 1 tsp | Enhances savory notes |
The potatoes are the foundation, so Russet potatoes are non-negotiable—their high starch content ensures that velvety texture. Buy them in bulk at Walmart or Costco for better value, and always peel and cube them uniformly for even cooking. The Campbell's Cream of Mushroom Soup adds depth without overpowering; the condensed version cuts prep time significantly. For the cheddar, sharp white cheddar from Cabot or Tillamook delivers that signature tang. Pre-shredded cheese works, but freshly grated melts more smoothly and prevents that dreaded clumping.
No cream of mushroom soup? Condensed chicken noodle soup works in a pinch, though the flavor profile shifts slightly. Substituting heavy cream with half-and-half lightens the texture, but you'll sacrifice that luxurious creaminess. For the cornmeal topping, fine grind is critical—it blends seamlessly with the flour. If you're out of cornmeal, almond flour at half the amount adds a nutty twist, though the texture will differ. The garlic and onion powders are easy to overlook, but they're what elevate this from basic to restaurant-quality. Toasting them lightly in a dry pan before adding to the topping mix intensifies their flavor dramatically.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 20-25 minutes until bubbly. Store leftovers in the fridge for up to 5 days, though the flavor peaks within the first two. For meal prep, assemble the casserole ahead and refrigerate uncovered for 24 hours before baking—this allows the flavors to meld and the crust to develop deeper color. Freeze unbaked portions for up to 3 months; thaw overnight in the fridge before baking. The topping can be pre-mixed and refrigerated separately for up to 3 days, making last-minute assembly effortless.

Step-by-step instructions for creamy Campbell's potato casserole
This method delivers a perfectly creamy, cheesy potato casserole with a golden, crisp cornmeal topping every time.
Prepare the Potato Base
Preheat your oven to 375°F and grease a 9x13-inch baking dish with the 0.5 cup butter, rubbing it evenly along the bottom and sides. This prevents sticking and creates a rich foundation for your casserole.
Peel the 3 lb russet potatoes and cut them into ½-inch cubes, ensuring even-sized pieces for uniform cooking. Spread them in a single layer on a baking sheet and toss with 1.5 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, and 1 tsp onion powder. Roast for 15 minutes to begin softening the edges while you prepare the sauce.
Create the Creamy Sauce Mixture
In a large mixing bowl, combine the 2 cans Campbell's Cream of Mushroom Soup, 1 cup heavy cream, 0.5 cup milk, and 2 cups shredded cheddar cheese. Whisk until the cheese is fully melted and the mixture is smooth, with no lumps remaining. This step ensures a velvety texture that coats every potato perfectly.
Remove the potatoes from the oven and transfer them to the mixing bowl with the sauce. Gently fold everything together until each potato cube is fully coated in the creamy mixture. The sauce should look glossy and well-distributed, indicating even flavor penetration. Transfer the potato mixture to the prepared baking dish and spread it out evenly.
Prepare the Golden Crisp Topping
In a medium bowl, whisk together the 1 cup cornmeal, 0.5 cup all-purpose flour, 1 tsp garlic powder, 1 tsp onion powder, and the remaining 0.5 tsp black pepper. This dry blend forms the crispy, golden crust that seals in moisture and adds texture contrast to the creamy filling.
Drizzle the melted 0.5 cup butter over the dry ingredients and mix with a fork until the mixture resembles coarse crumbs with some butter streaks remaining. The texture should be slightly sandy but hold together when pressed. Sprinkle this evenly over the potato mixture in the baking dish, pressing down gently with your fingers to ensure full coverage.
Bake to Perfectly Creamy Perfection
Place the baking dish on the middle rack of your preheated oven and bake for 45-50 minutes. The casserole is done when the top is deep golden brown and the edges are slightly crispy, while the center still shows a gentle jiggle when shaken. This indicates the filling is hot throughout but hasn't overcook into dryness.
Remove from the oven and let the casserole rest for 10 minutes before serving. This resting period allows the creamy filling to set slightly, making it easier to cut and serve while maintaining that perfect balance of creamy texture and crispy topping. Serve warm with a side of steamed green beans or a simple garden salad.
Pro Tips For Making Campbell'S Potato Casserole
- PRE-COOK POTATOES: Slice your Russets before boiling—thin, even slices (about ¼-inch) cook faster and soak up the creamier sauce better. I used to skip this and ended up with gummy potatoes; pre-cooking guarantees tender slices that hold their shape.
- SALT THE WATER: Boil your potato slices in salted water (1 tbsp per gallon)—it seasons them properly and prevents blandness later. The soup’s already salty, but the potatoes need their own kick to balance the cheesy richness.
- SKIP THE MIXING: Don’t stir the soup and cream mixture after adding it to the potatoes—it breaks the layers and makes the top soggy. Just pour it in and let it settle; the cheese will melt evenly on its own.
- BREAD THE CHEESE: Toss the shredded cheddar with 1-2 tbsp cornmeal before sprinkling—it creates a crispier, thicker crust instead of a greasy mess. (Yes, it sounds weird, but it works—trust me.)
Creative variations of these flavors
Cheesy Bacon Twist
Crispy bacon adds a smoky depth that takes this casserole to the next level. Cook 6 slices of thick-cut bacon until crispy, then crumble it into the creamy sauce mixture before transferring to the baking dish.
For extra indulgence, top with an additional ¼ cup crumbled bacon mixed into the cornmeal topping. I like using Oscar Mayer smoked bacon from my local grocery store—it’s affordable and delivers that perfect smoky flavor. 🥓
Vegetable Boost
Add fresh veggies for a lighter, more colorful version. Stir in 1 cup frozen broccoli florets or ½ cup finely chopped bell peppers after mixing the sauce with the potatoes. For a heartier dish, try ½ cup sautéed mushrooms or 1 cup corn kernels (fresh or canned).
I often use frozen veggies for convenience—they’re pre-cut and ready to go. Just make sure to drain excess liquid before adding to avoid a watery casserole. 🥦
Creamy Spinach Version
Swap out some of the cheddar for a tangy, creamy twist by adding 10 oz frozen chopped spinach½ cup sour cream for extra richness.
The spinach adds a vibrant green color and a subtle earthiness that pairs beautifully with the Campbell’s soup base. For an extra boost, sprinkle ¼ cup grated Parmesan cheese over the cornmeal topping before baking. 🍃
Breakfast Casserole Upgrade
Transform this into a breakfast casserole by adding 4 scrambled eggs mixed into the creamy potato base. Top with an extra ½ cup shredded cheddar and a sprinkle of chopped chives for a fresh finish.
Bake as directed, then broil for 2-3 minutes at the end to create a golden, slightly crispy top. Serve with a side of hash browns or crispy home fries for a hearty weekend brunch. 🍳
Slow Cooker Adaptation
For a hands-off version, combine all ingredients in a 6-quart slow cooker and cook on LOW for 4-5 hours or HIGH for 2-3 hours. After cooking, transfer to a baking dish and broil for 5-7 minutes to crisp the topping.
This method is perfect for busy weeknights when you don’t want to stand over the stove. I use my Hamilton Beach slow cooker—it’s reliable and easy to clean. 🍲
Gluten-Free Option
Make this casserole gluten-free by replacing the all-purpose flour with ½ cup gluten-free flour blend and using 1 cup gluten-free cornmeal. Ensure your Campbell’s soup is also gluten-free, and check the labels on any seasoning mixes.
The texture will be slightly different but still delicious. For extra crunch, sprinkle ½ cup crushed gluten-free cornflakes over the top before baking. 🌾

Frequently asked questions
Can I make this potato casserole ahead of time?
Assemble the casserole in your baking dish and refrigerate it uncovered for 24 hours before baking. This lets the flavors meld beautifully and gives the topping a deeper golden color. For make-ahead freezing, prepare the dish as directed but don't bake it. Cover tightly with foil and plastic wrap, then freeze for up to 3 months. Thaw overnight in the fridge before baking.
What's the secret to getting a crispy cornmeal topping?
The key is mixing the cornmeal with melted butter until it reaches a sandy texture with visible butter streaks. Press it firmly onto the potato mixture before baking, and use the middle oven rack for even heat circulation. For extra crispiness, broil for 2-3 minutes at the end of cooking, watching closely to avoid burning.
Can I substitute Campbell's Cream of Mushroom Soup?
Yes, but the flavor will change slightly. For a similar creamy texture, try condensed chicken noodle soup or cream of chicken soup. For a richer taste, use 1 cup sour cream or ½ cup Greek yogurt mixed with 1 cup milk as a base. The Campbell's soup adds that signature umami depth that's hard to replicate with other ingredients.
Why did my casserole turn out watery?
Watery casseroles usually happen from overmixing the potatoes or using too much liquid. Make sure to drain all excess water from cooked potatoes before mixing with the sauce. Also, avoid using low-fat dairy products—they can't provide the same creamy texture. If you're adding veggies, squeeze out all excess moisture before incorporating them into the mixture.
How can I make this casserole kid-friendly?
Cut the casserole into fun shapes using cookie cutters before baking, or arrange the potato mixture into individual portions in small baking dishes. For picky eaters, try mixing in ½ cup finely grated carrots or ¼ cup finely chopped ham into the creamy base. The familiar flavors and textures will make it more appealing to children while keeping the comforting taste they love.
