Ingredients for campbell's cheesy potato casserole
Campbell's Cream of Mushroom soup and crispy potato layers transform into this iconic comfort dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 ½ lb | Cut into 1/2-inch thick slices |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, 4 oz per cup |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Panko Breadcrumbs 🍞 | 1 cup | For crispy topping |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Green Onions 🌱 | ¼ cup | Sliced, for garnish |
| Bacon 🥓 | ½ lb | Cooked crispy, crumbled |
The foundation begins with Russet potatoes—their high starch content ensures that signature fluffy texture. Opt for organic Russets from Whole Foods or your local market's fresh produce section; they hold up better during parboiling. The Campbell's Cream of Mushroom soup is non-negotiable here—its creamy consistency and umami depth create the velvety base. For the cheese, sharp cheddar from a block (like Cabot or Tillamook) melts more smoothly than pre-shredded varieties, which often contain anti-caking agents that prevent proper melting. The Panko breadcrumbs should be toasted lightly before mixing with butter to maximize crispiness—Trader Joe's carries excellent quality at a reasonable price.
No Campbell's Cream of Mushroom soup? Homemade mushroom cream sauce works as a substitute—sauté mushrooms in butter, add cream and a touch of thyme, then blend until smooth. Pre-shredded cheese is convenient but shred your own for better texture; it melts more evenly. Running short on Panko? Italian breadcrumbs or crushed cornflakes provide a similar crunch. The bacon adds a smoky depth that pairs beautifully with the creamy potatoes—thick-cut bacon from Costco renders the most flavor when cooked crispy. For an extra boost, consider adding a pinch of smoked paprika to the breadcrumb mixture for a subtle smokiness that mimics the bacon flavor.
This casserole reheats beautifully—cover with foil and bake at 350°F (175°C) for 15-20 minutes to revive crispiness. Store leftovers in the refrigerator for up to 5 days, covered tightly to prevent drying. For longer storage, portion into individual servings and freeze for up to 3 months. The topping can be prepped ahead and stored separately—just sprinkle fresh green onions on top before baking. For a restaurant-quality finish, broil the casserole for the last 2-3 minutes to achieve that signature golden-brown crust that shatters at every bite.

Step-by-step instructions for Campbell's cheesy potato casserole
This method delivers a perfectly layered casserole with a crispy golden crust and creamy cheddar filling every time.
Prepare the Potato Layers
Preheat your oven to 375°F and grease a 9x13-inch baking dish with a light coating of the 0.5 cup butter. Peel and slice the 3.5 lb russet potatoes into ½-inch thick slices. You'll need about 6-7 layers of potatoes for proper stacking.
Arrange the potato slices in the prepared baking dish in a single layer, slightly overlapping them like shingles. This creates a stable foundation and ensures even cooking. Season each layer lightly with 0.25 tsp salt and 0.125 tsp black pepper—just enough to enhance flavor without overpowering the cheese. Repeat this layering process until all potatoes are used, finishing with a final layer of potato slices on top.
Create the Creamy Cheese Mixture
In a large bowl, combine the 2 cans Campbell's Cream of Mushroom Soup, 1 cup milk, 1 tsp garlic powder, and 1 tsp onion powder. Whisk until completely smooth—this ensures the sauce will distribute evenly between the potato layers. The mixture should be thick but pourable, with a creamy consistency that will blend seamlessly with the melted cheese.
Gradually fold in 1 cup of the 2 cups sharp cheddar cheese using a rubber spatula. Be gentle to avoid creating air pockets, which could lead to uneven melting. Pour this mixture evenly over the potato layers in the baking dish, pressing down lightly with the back of a spoon to help it seep between the slices. This step is critical for achieving that signature creamy texture throughout.
Add the Crispy Topping Layer
In a separate bowl, mix the 1 cup panko breadcrumbs, remaining 1 cup sharp cheddar cheese, 0.25 tsp salt, and 0.125 tsp black pepper. Stir in the 0.5 lb cooked bacon (crumbled) and 0.25 cup sliced green onions until evenly distributed. This topping will create a golden, crispy crust while adding savory depth and freshness.
Sprinkle this mixture evenly over the top of the casserole, pressing down gently to ensure good contact with the cheese layer beneath. The panko should cover the entire surface completely—this is what will give you that perfect crunch when served. For extra insurance, you can lightly press down with a glass or the bottom of a measuring cup to compact the topping.
Bake to Golden Perfection
Transfer the baking dish to the preheated 375°F oven and bake for 45-50 minutes. The casserole is ready when the top is deep golden brown and the edges are bubbling vigorously. You'll notice the cheese has melted completely and the potatoes are tender when pierced with a fork—no resistance should remain.
For best results, let the casserole rest for 10-15 minutes before serving. This resting period allows the layers to set slightly and prevents any cheese from running out when you cut into it. The crispy topping will maintain its texture, while the interior remains creamy and perfectly heated. Serve warm with a side of steamed green beans or a simple salad for a complete meal.
Pro Tips For Making Campbell'S Cheesy Potato Casserole
- BOIL POTATOES UNTIL SOFT: The recipe might call for "boiled" potatoes, but I learned the hard way—actually tender means no one will complain about mushy bites. Cut them into even ½-inch slices, boil in salted water for 8–10 minutes (test with a fork), then drain thoroughly before mixing. Overcooked potatoes turn to glue; undercooked ones stay crunchy. Aim for fork-tender, not falling-apart.
- GRATE CHEESE FINE: Skip the big chunks unless you want a casserole that looks like a science experiment. Sharp cheddar melts best when grated very fine—almost like powdered sugar. Use the smallest holes on your box grater, or pulse in a food processor. The finer the cheese, the smoother the sauce and the better it clings to the potatoes. (Yes, it’s tedious, but trust me on this one.)
- SAUCE FIRST, POTATOES SECOND: Mix the Campbell’s soup, milk, and butter before adding the potatoes. Heat the sauce separately until it’s just simmering—this helps the cheese melt fully and coats the potatoes evenly. Dumping cold potatoes into cold sauce = clumpy, uneven texture. Warm the sauce first, then fold in the potatoes gently. Less stirring = fewer lumps.
- BAKE COVERED THEN UNCOVERED: Start this casserole with the foil on, but don’t leave it that way. Bake covered at 350°F for 30 minutes to let the moisture distribute and the cheese start melting. Then, remove the foil and bake another 10–15 minutes—this creates that golden, crispy top everyone loves. Skipping the uncovered step means a sad, soggy crust. (Your future self will notice.)
Flavor customization for this campbell's cheesy potato casserole
Creamy Variations
Swap the Campbell’s Cream of Mushroom Soup for cream of celery soup to add a refreshing, slightly earthy flavor that pairs beautifully with the cheesy potatoes. I like Campbell’s Cream of Celery Soup for convenience, but homemade versions with fresh celery and chicken broth work too.
For a richer option, mix in ½ cup sour cream with the cheese sauce—it adds a velvety texture that’s irresistible. 🥄
Cheese Swaps
Replace sharp cheddar with Monterey Jack for a milder, creamier melt that’s perfect for families. Or try Gruyère for a nutty, complex flavor—just reduce the amount to 1½ cups since it’s stronger.
For a smoky twist, add ½ cup smoked Gouda to the topping layer. I’ve also seen Colby Jack work well, especially when mixed with a little Cheddar for balance.
Protein Add-Ins
Boost the dish with ½ lb cooked ham or sausage crumbles instead of bacon for a different savory profile. I love adding diced breakfast potatoes (pre-cooked and cooled) for extra heartiness.
For a vegetarian option, fold in ½ cup corn kernels or sautéed mushrooms—they absorb the creamy sauce beautifully. Just be sure to drain any excess liquid from the veggies first.
Spicy Kick
Add ½ tsp cayenne pepper or 1 tsp hot sauce (like Frank’s RedHot) to the cheese mixture for a subtle heat. For a smoky-spicy topping, mix 1 tbsp smoked paprika and ½ tsp chipotle powder into the breadcrumb layer.
I also like sprinkling chopped jalapeños on top before baking—just remove the seeds for less heat. 🌶️
Herb Infusions
Brighten the dish with 1 tbsp fresh chives or 2 tbsp chopped parsley mixed into the cheese sauce. For a Mediterranean twist, add 1 tsp dried oregano and ½ tsp lemon zest to the topping.
I’ve also experimented with 1 tsp fresh thyme in the soup mixture—it adds an earthy depth that complements the mushrooms. Fresh herbs should be added just before serving to preserve their flavor.
Crunchy Toppings
Swap Panko for crushed tortilla chips for a Mexican-inspired crunch or use cornflake crumbs for a lighter texture. For extra indulgence, top with crushed potato chips (like Kettle Brand) in the last 10 minutes of baking.
I’ve even seen crumbled bacon + crushed Ritz crackers work as a buttery, crispy hybrid topping—it’s a game-changer for texture lovers. 🥔

Frequently asked questions
Can I make this potato casserole ahead of time?
Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, add 10-15 minutes to your baking time (about 55-60 minutes total) to account for the cold start. For best results, cover with foil during the first 30 minutes of baking to prevent over-browning.
Why did my casserole turn out soggy?
Soggy casseroles usually happen from one of two issues: overcooking the potatoes before layering or not pressing the topping down firmly. Always parboil potatoes for just 5 minutes (not longer) to keep them tender but firm. Also, ensure your breadcrumb topping is pressed down with a glass or measuring cup to create a proper barrier between the cheese and the crunchy layer.
What can I substitute if I don't have Campbell's Cream of Mushroom Soup?
Use 2 cups heavy cream + 2 tbsp cornstarch cooked until thickened, or make a quick roux with 4 tbsp butter + 4 tbsp flour mixed with 2 cups milk. For a vegetarian option, blend 1 cup cooked mushrooms + 1 cup cashew cream + 1 tbsp nutritional yeast until smooth. The key is achieving that creamy, slightly thick consistency.
How do I make this casserole lower in fat?
Swap the butter in the topping for light olive oil and use low-fat cheddar (or 2% milk cheese). Reduce the bacon to ¼ lb or use turkey bacon, and replace Panko with whole-grain breadcrumbs. The texture will be slightly different but still delicious—just expect a less crispy crust.
Can I bake this in a different sized dish?
Yes! For a 8x8-inch dish, reduce ingredients by 33% (about 2 lb potatoes, 1 can soup, 1 cup cheese). For a 11x15-inch dish, increase by 50% (about 5 lb potatoes, 3 cans soup, 3 cups cheese). Always adjust baking time—smaller dishes bake 5-10 minutes faster, while larger ones may need 10-15 minutes extra.
