Ingredients for campbell's potato casserole
Pantry staples that transform into nostalgic, crispy-cheesy comfort food perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lbs | Peeled, sliced into 1/4-inch rounds |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Milk 🥛 | 1 cup | Whole milk preferred |
| Cornmeal 🌾 | ½ cup | Fine grind for crispiness |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium or sharp cheddar |
| Butter 🧈 | ½ cup | Melted, unsalted preferred |
| All-Purpose Flour 🌾 | ¼ cup | For crispy topping |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | 1 tsp | For extra flavor |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |
| Sour Cream 🍦 | ½ cup | Full-fat for creaminess |
The potatoes are the heart of this dish—Russets are ideal because they hold their shape when sliced thin. Peeled and uniform slices cook evenly, so take the time to slice them all the same thickness. I always buy the 3-pound bag at Walmart—it’s the best price, and it’s perfect for this recipe. If you’re short on time, the pre-peeled bags work too, but they’re pricier. The secret to that crispy top? Don’t skip the cornmeal—it’s what gives it that nostalgic crunch. Grab the fine grind at Kroger or any grocery store; it’s usually near the flour.
No Campbell’s cream of mushroom soup? Homemade version with cream, mushrooms, and a dash of thyme works just as well. Short on cheddar? Swiss or Monterey Jack add a nice twist—just make sure it’s freshly shredded (pre-shredded gets gummy). The sour cream adds richness, but Greek yogurt at half the amount cuts calories without sacrificing creaminess. Want extra crisp? Mix 1 tbsp of crushed cornflakes into the cornmeal topping—trust me, it’s a game-changer. And if you’re out of milk, half-and-half or evaporated milk keeps the same creamy texture.
This casserole reheats like a dream—just 350°F for 15-20 minutes until bubbly. Leftovers keep for 4-5 days in the fridge, but honestly, it’s even better the second day. For meal prep, assemble it in a greased 9x13-inch baking dish and refrigerate uncovered for 1 hour before baking—this helps the top get extra crispy. Freezes beautifully for up to 3 months—just bake straight from frozen, adding 10-15 minutes to the cooking time. Double the recipe and freeze half for lazy weeknights!

Step-by-step instructions for Campbell's potato casserole
Here's how to create that irresistible crispy top and creamy, cheesy filling everyone will beg for!
👨🍳 Step 1: Prep the Potatoes for Maximum Creaminess
Peel the 3 lbs russet potatoes and slice them into even ¼-inch rounds. I use a mandoline for perfect thickness, but a sharp knife works too—just stay consistent. Soak the potato slices in cold water for 10 minutes to remove excess starch, then drain well and pat dry with paper towels. This step prevents a gummy texture and ensures your casserole stays tender.
While the potatoes soak, preheat your oven to 375°F. I like to use the middle rack for even baking. The potatoes will absorb the creamy mixture better when they're at room temperature, so let them sit in a colander for 5 minutes before assembling. This little prep step makes all the difference in texture!
🍳 Step 2: Make the Creamy Cheese Sauce Foundation
In a large bowl, combine the 2 cans Campbell's cream of mushroom soup, 1 cup milk, 0.5 cup melted butter, 0.5 cup sour cream, 1 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, and 1 tsp onion powder. Whisk everything together until smooth and fully combined. This is your flavor base—don't skip tasting it now to adjust seasoning if needed!
Add the drained potatoes to the sauce mixture and toss gently but thoroughly to coat each slice evenly. You want every potato to be fully saturated with the creamy sauce. I like to use my hands for this part—it ensures even distribution and helps the sauce cling to the potatoes. Transfer the potato mixture to a greased 9x13-inch baking dish and spread it out evenly.
🥘 Step 3: Create the Crispy Cornmeal Topping
In a medium bowl, mix together the 0.5 cup cornmeal, 2 cups shredded cheddar cheese, and 0.25 cup all-purpose flour. This is your magic topping that creates that irresistible crispy crust. Sprinkle this mixture evenly over the potato layer in the baking dish, pressing down gently with your fingers to help it adhere.
Here's the thing—don't be shy with the topping! You want it thick enough to get properly crispy. I like to make little peaks and valleys with my fingers to create that pull-apart texture that makes this casserole so addictive. The cornmeal gives it that perfect crunch while the cheese adds richness.
🔥 Step 4: Bake to Golden, Crispy Perfection
Place the baking dish on the middle rack of your preheated oven and bake for 45-50 minutes. You're looking for the top to turn a beautiful golden brown with crispy edges that look almost caramelized. The casserole is done when the top is crispy and the cheese is fully melted throughout.
I know it's tempting to check early, but resist! The top needs time to get properly crispy. If you're worried about it browning too quickly, tent loosely with foil after 30 minutes and then uncover for the final 15-20 minutes to crisp up. The internal temperature should reach 180°F when done.
⏰ Step 5: Rest and Serve with Maximum Crunch
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting time allows the cheese to set slightly and makes it easier to get that perfect pull-apart texture. The contrast between the crispy top and creamy filling is what makes this casserole so amazing!
Serve immediately with a side of green beans or a simple salad. The crispy cornmeal topping should be golden and crunchy, while the potatoes underneath remain tender and creamy. This is comfort food at its finest—easy to make but always impressive when served to guests!
Pro Tips For Making Campbell'S Potato Casserole
- PRE-COOK POTATOES: Toss sliced Russets in cold water while prepping the rest—it stops browning and keeps them from turning to mush in the oven. I learned this the hard way after serving a soggy casserole once. Drain and pat very dry before mixing with soup.
- SKIP THE MIXING BOWL: Spread the cornmeal directly in your baking dish first—it creates a crispier bottom layer without clumping. I used to stir it into the soup, and the texture was always uneven. Just sprinkle, then dump the potato-soup mix on top.
- COVER THEN BAKE: Tent with foil for the first 30 minutes—this traps steam and ensures even cooking before the cheese gets crispy. After that, uncover to let the top brown. My first attempt had a pale, sad middle because I rushed this step.
- TOAST THE CHEESE: Sprinkle shredded cheddar right out of the fridge? Nope. Microwave it for 20 seconds first—it melts faster and stays gooey, not clumpy. I was skeptical until I tried it, and now it’s non-negotiable.
Flavor customization for this dish
Cheesy Variations
Swap the cheddar for Monterey Jack to add a milder, creamier flavor that melts beautifully. I've also had great success with Swiss cheese—it adds a nutty depth that pairs perfectly with the mushrooms in the Campbell's soup.
For a spicy kick, mix in ½ cup pepper jack with the cheddar. 🧀
Want extra richness? Add ¼ cup cream cheese to the sauce mixture for a velvety texture. Or try blue cheese crumbles in the topping for a bold, tangy twist that surprises everyone.
My Nonna used to add Parmesan to the cornmeal topping for a salty crunch—just 2 tablespoons makes a difference.
Herb & Spice Twists
Fresh herbs elevate this classic. Stir 2 tablespoons chopped chives or 1 tablespoon dried thyme into the sauce for an aromatic boost. I also love adding 1 teaspoon smoked paprika to the cornmeal topping for a subtle smokiness that pairs perfectly with the mushrooms. 🌿
For a zesty kick, mix 1 teaspoon lemon zest into the sauce or sprinkle ½ teaspoon cayenne pepper over the top before baking. If you're feeling adventurous, try 1 tablespoon fresh dill—it adds a bright, fresh note that cuts through the richness.
Protein Add-Ins
Turn this into a full meal by mixing in 1 cup cooked bacon bits or ½ cup crumbled sausage with the potatoes. For a lighter option, try ½ cup cooked chicken or ½ cup black beans—both add protein without overpowering the creamy flavor. 🍳
Want extra indulgence? Top with ½ cup cooked ham or ¼ cup crispy fried onions right before serving. I once added 2 tablespoons chopped green onions after baking for a fresh pop of color and texture that guests loved.
Vegetable Boosts
Add 1 cup steamed broccoli florets or 1 cup sautéed mushrooms to the potato layer for extra veggies. For a New England touch, try ½ cup diced celery—it adds a subtle crunch that pairs perfectly with the creamy sauce. 🥦
Roasted red bell peppers or zucchini work beautifully too. Just slice them thin and mix them in with the potatoes. I once added ½ cup roasted garlic for a mellow, sweet depth that surprised everyone at the dinner table.
Dairy-Free Options
For a dairy-free version, replace the milk with 1 cup unsweetened almond milk and use 2 cups shredded mozzarella substitute (like Miyoko's). The cornmeal topping can be made with 2 tablespoons nutritional yeast for a cheesy flavor without dairy. 🌱
Swap sour cream for ½ cup coconut yogurt and butter for ½ cup olive oil in the sauce. The texture stays creamy, and the flavor is still rich and satisfying. Trust me, even cheese lovers won't miss the dairy in this version!

Frequently asked questions
Can I make this potato casserole ahead of time?
Assemble the dish in a greased 9x13-inch baking dish and refrigerate uncovered for 1 hour before baking. This helps the topping get extra crispy. For make-ahead meals, bake it completely, then cool to room temperature. Store covered in the fridge for 4-5 days—it reheats beautifully at 350°F for 15-20 minutes until bubbly.
What if I don't have cornmeal for the topping?
No cornmeal? No problem! Swap it for ½ cup crushed cornflakes or ½ cup panko breadcrumbs for a similar crispy texture. For extra richness, mix in 2 tablespoons melted butter with the breadcrumbs. The topping will still be delicious—just slightly different in crunch.
Why did my casserole turn out gummy instead of crispy?
Gummy texture usually means the potatoes absorbed too much moisture. Make sure to pat them completely dry after soaking and draining. Another common mistake is undercooking—bake until the top is golden brown and crispy (about 45-50 minutes). If it's still soft, broil for 2-3 minutes at the end for extra crispiness.
Can I use sweet potatoes instead of russets?
Yes, but with a few adjustments! Sweet potatoes hold their shape better, so you can skip soaking them. For extra flavor, add ½ teaspoon cinnamon or 1 teaspoon maple syrup to the sauce. The texture will be slightly denser, but the cheesy topping will still be delicious.
How do I make this casserole extra cheesy?
Double the cheese to 4 cups shredded cheddar and add ½ cup cream cheese to the sauce for a velvety texture. For a decadent twist, sprinkle ½ cup mozzarella on top before baking. The extra cheese creates a gooey, pull-apart perfection that disappears fast!
