Ingredients for campbell's potato casserole
Pantry staples meet comfort food magic in this Campbell's potato casserole.
| Ingredient | Amount | Notes |
|---|---|---|
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz can each, unsalted preferred |
| Russet Potatoes 🥔 | 3 lb | Medium-sized, peeled and sliced thin |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, not pre-shredded (block preferred) |
| Butter 🧈 | ½ cup | Unsalted, melted, full-fat |
| Dry Breadcrumbs 🍞 | ½ cup | Panko or fine dry breadcrumbs |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |

The Campbell's cream of mushroom soup is the flavor anchor here. Opt for the unsalted version if available—it gives you better control over seasoning. I always grab the 10.5 oz cans from the store's canned soup aisle, but the 10.75 oz size works too. For the potatoes, Russets are non-negotiable—their high starch content makes them creamy when cooked. Medium-sized potatoes (about 6-8 oz each) slice evenly, but don't stress if yours vary slightly. The key is thin, even slices for consistent cooking. Grocery store brands work perfectly here—no need for organic or specialty potatoes.
No Campbell's soup? Homemade mushroom cream sauce is the next best thing—sauté mushrooms in butter, add cream and a splash of milk, then season with salt and pepper. Pre-shredded cheese gets clumpy, so grate your own from a block if you can. The breadcrumbs are where texture happens—Panko gives extra crispiness, but regular dry breadcrumbs work too. Short on milk? Half-and-half or light cream adds richness without overpowering. The garlic and onion powders are subtle but essential—Diamond Crystal or Morton are reliable brands for consistent flavor. If you're feeling fancy, add a pinch of nutmeg to the cheese layer for warmth.
This casserole tastes even better the next day, so make it ahead if you can. Assemble everything, cover with foil, and refrigerate for up to 24 hours before baking. Once baked, store leftovers in an airtight container for 4-5 days—the flavors meld beautifully overnight. For freezing, bake as directed, then cool completely before wrapping tightly in foil. It keeps for 3 months in the freezer, though the topping may lose some crispness. Reheat covered at 350°F for 15-20 minutes to restore that golden crunch.

Step-by-step instructions for Campbell's potato casserole recipe
A rich, creamy potato casserole with crispy breadcrumb topping and bold cheddar flavor—ready in one pan.
Prepare the Potatoes and Seasoning Base
Start by peeling the 3 lb russet potatoes and slicing them into ¼-inch thick rounds. This even thickness ensures they cook uniformly. Place the sliced potatoes in a large bowl and toss them with 0.5 cup milk, 1.5 tsp salt, 0.5 tsp black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder. The milk helps tenderize the potatoes while the seasonings infuse flavor evenly. Let them sit for 5 minutes to absorb the liquid.
While the potatoes marinate, preheat your oven to 375°F. This temperature guarantees a creamy center without overcooking the edges. Grease a 9x13-inch baking dish with 0.25 cup of the melted butter (reserve the rest for later). The greased pan prevents sticking and makes cleanup effortless.
Layer Potatoes and Creamy Sauce
Spread half of the seasoned potato slices evenly across the bottom of the prepared baking dish. Pour 1 can of Campbell's Cream of Mushroom Soup over the potatoes, spreading it evenly with a spatula. This layer ensures every slice gets coated in the rich, creamy sauce.
Top with the remaining potato slices, pressing down gently to create an even layer. Pour the second can of soup over the top, again spreading it to cover all potatoes completely. Sprinkle 2 cups sharp cheddar cheese evenly over the sauce. The cheese will melt into a luscious, gooey blanket, delivering that promised creamy texture.
Create the Crispy Breadcrumb Topping
In a small bowl, melt the remaining 0.25 cup butter and mix it with 0.5 cup dry breadcrumbs and 1 tbsp parsley flakes. The parsley adds a fresh, bright contrast to the rich cheese and potatoes. Sprinkle this mixture evenly over the cheese layer, pressing down lightly with a fork to help it adhere. This step is crucial—it creates the signature crispy topping that adds texture and prevents the cheese from over-browning.
Bake to Golden Perfection
Place the baking dish in the preheated oven and bake for 45-50 minutes. You'll know it's ready when the top is golden brown and the edges are bubbling. The cheese should be fully melted, and the breadcrumbs should be crispy to the touch. If the top isn't brown enough after 45 minutes, broil for 2-3 minutes on high, watching closely to avoid burning.
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting time allows the layers to set slightly, making it easier to slice cleanly. The result is a creamy, cheesy potato casserole with a crispy, golden topping that delivers on every bite.
Pro Tips For Making Campbell'S Potato Casserole
- PRECOOK POTATOES UNTIL FALL-APART: Boil or microwave the Russets until they’re so tender a fork slides in like butter—no one likes that weird half-raw bite. Drain well, then mash them right in the pot with a splash of the soup to keep things smooth. (Yes, even if you’re impatient like me.)
- SALT THE CHEESE FIRST: Grate that sharp cheddar, then toss it in a bowl with a pinch of salt and a few drops of water—it melts better and sticks to the breadcrumbs like glue. Skip this, and you’ll end up with clumpy, sad cheese pull.
- BUTTER THE BREADCRUMBS: Mix the dry breadcrumbs with melted butter (about 2 tablespoons) before sprinkling—this guarantees a crispy top instead of a sad, dry crust. I learned this the hard way after my first batch came out like cardboard.
- BAKE COVERED THEN UNCOVERED: Start with foil on tight for the first 20 minutes to let the soup steam into the potatoes, then uncover and broil for 3–5 minutes—this makes the cheese bubble and the top golden. No broiling? Just crank the oven to 400°F and watch it closely.
Essential equipment for this recipe
Baking Dish Essentials
You'll need a sturdy 9x13-inch baking dish—I use CorningWare for its even heat distribution and non-stick surface. If you don't have one, a heavy-duty aluminum pan works too, but grease it well with butter or olive oil to prevent sticking.
Avoid glass dishes thinner than ¼ inch—they can crack under high heat. For extra insurance, I line my dish with parchment paper cut to fit, which makes cleanup a breeze. 🧈
Oven Thermometer Check
Your oven's temperature gauge can be off by 25°F or more, so I always use an oven thermometer (like the Taylor Precision model) to verify 375°F. Place it in the center rack while preheating—this ensures your casserole bakes evenly.
If your oven runs hot, reduce the temperature to 350°F to prevent over-browning. Trust me, this small step makes a huge difference in texture.
Potato Slicing Tools
For even slices, a mandoline slicer is ideal, but a sharp chef's knife works just fine if you're careful. I prefer the OXO Good Grips mandoline for its safety features. Slice potatoes ¼-inch thick—any thicker, and they'll stay undercooked; any thinner, and they'll turn mushy.
Keep a bowl of cold water nearby to rinse slices between batches to prevent browning. This keeps your prep organized and ensures consistent cooking.
Cheese Grater Upgrade
Pre-shredded cheese contains anti-caking agents that make it clump when melted. Invest in a microplane or box grater to shred your own sharp cheddar—it melts smoother and tastes fresher. I love the KitchenAid 4-Sided Grater because it handles large blocks efficiently.
For extra flavor, grate the cheese right before assembling so it stays vibrant. If you're short on time, Kraft Natural shredded cheese is the closest store-bought alternative.
Breadcrumbs Prep
For the crispy topping, I recommend Panko breadcrumbs—they're lighter and crispier than regular breadcrumbs. If you're using dry breadcrumbs, pulse them in a food processor for 10-15 seconds to break up any lumps. Keep a small bowl ready to mix with melted butter and parsley flakes.
Pro tip: Toast the breadcrumbs in a dry pan over medium heat for 2-3 minutes before mixing with butter to enhance their flavor. This step adds an extra layer of texture that takes your casserole to the next level. 🍞

Frequently asked questions
Can I substitute Campbell's Cream of Mushroom Soup with another flavor?
For a creamy texture, try Campbell's Cream of Chicken, Celery, or even Cream of Potato Soup. For a bolder flavor, swap in a can of cream of broccoli soup or cream of onion soup. Just reduce the milk to ¼ cup if using a thicker soup to maintain the right consistency. The key is keeping the same creamy base.
Why did my casserole turn out watery instead of creamy?
Watery results usually happen when potatoes release too much moisture. To fix this, pat sliced potatoes very dry with paper towels before assembling, and reduce baking time by 5-10 minutes. Also, ensure your baking dish isn't too large—stick to a 9x13-inch pan for proper cooking. Cover with foil for the first 30 minutes to trap steam.
Can I make this casserole ahead of time?
Yes! Assemble the casserole completely, cover tightly with foil, and refrigerate for up to 24 hours before baking. For best results, bake it straight from the fridge—add 10-15 minutes to the cooking time. Leftovers keep well in an airtight container for 4-5 days, and it freezes beautifully for up to 3 months. Reheat covered at 350°F for 20 minutes to restore crispiness.
What's the secret to a perfectly crispy breadcrumb topping?
The crispy topping depends on three things: Panko breadcrumbs (they're lighter), butter (not oil), and pressing it down gently with a fork. For extra crunch, toast the breadcrumbs in a dry pan for 2-3 minutes before mixing with melted butter. Avoid overbrowning by keeping the oven at 375°F and not broiling longer than 2-3 minutes at the end.
Can I add vegetables or protein to this casserole?
Stir in 1 cup frozen peas or diced bell peppers with the potatoes for extra veggies. For protein, add ½ cup cooked ham or chicken breast between potato layers. Keep portions balanced—too much extra filling can make the casserole dense. If adding wet ingredients (like cooked veggies), reduce the milk to ¼ cup to maintain the right texture.
