Ingredients for campbell's scalloped potatoes
Six ingredients make this classic casserole shine—creamy, tangy, and perfectly crisp-edged in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced (1/8-inch thick) |
| Campbell's Cream of Mushroom Soup 🍄 | 2 cans | Condensed, 10.5 oz each |
| Sour Cream 🥛 | 1 ½ cups | Full-fat for creaminess |
| Sharp White Vinegar 💧 | ½ cup | For tangy brightness |
| Sharp Cheddar Cheese 🧀 | 2 cups | Freshly grated, block preferred |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
| Bacon 🥓 | 6 oz | Crumbled, optional richness |
| Fresh Chives 🌿 | ¼ cup | Chopped, for garnish |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy topping |
The potatoes are everything here. Russets hold their shape best when thinly sliced—mandoline slicer makes this job effortless, but a sharp knife works too. Look for firm, unblemished potatoes at Whole Foods or your local market—they should feel heavy for their size. The vinegar is non-negotiable; white vinegar gives the cleanest tang, but apple cider works in a pinch. For the cheese, sharp cheddar melts beautifully, but a mix of cheddar and Gruyère adds complexity. I always grab extra—half goes in the casserole, half gets sprinkled on top before baking.
No Campbell's soup? Homemade mushroom sauce (sautéed mushrooms, cream, and a splash of white wine) works beautifully. Short on sour cream? Greek yogurt at half the amount keeps it tangy. The bacon can be swapped for crumbled sausage or smoked gouda bits for a different flavor profile. Fresh herbs? Dried chives at one-third the amount save you a trip to the market. Panko topping too much work? Crushed potato chips give the same crispy magic with zero effort. The key is balancing the tang—don't skip the vinegar, but don't overdo it either.
This casserole tastes even better the next day, so double the batch for leftovers. Store covered in the fridge for 4-5 days, or freeze portions for up to 3 months. Reheat covered at 350°F until bubbly—about 20 minutes. For extra crispiness, broil for 2-3 minutes at the end. I always serve this with a simple green salad and roasted chicken—it's the ultimate comfort food combo.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this when I’m too tired to scrub pots—just slice, layer, and bake. The vinegar cuts the prep time in half by keeping those potatoes from browning while you work, and the cheese soup does all the flavor heavy lifting.

Step-by-step instructions for cheesy vinegar-kissed scalloped potatoes
Here's how to build layers of creamy, tangy, crisp-topped scalloped potatoes with minimal effort.
👨🍳 Step 1: Prep the Potatoes and Build the Flavor Base
First, slice the 3 lb russet potatoes into ⅛-inch thick rounds—this ensures even cooking and perfect layers. I use a mandoline for precision, but a sharp knife works too. Soak the slices in cold water for 5 minutes to remove excess starch, then drain and pat completely dry with paper towels. This step prevents a gummy texture.
In a large bowl, whisk together the 2 cans Campbell's cream of mushroom soup, 1.5 cups sour cream, 0.5 cup sharp white vinegar, 0.5 cup milk, 0.5 cup melted butter, 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. The vinegar adds that signature tang while balancing the richness. Stir in 2 cups freshly grated sharp cheddar cheese until fully combined—this is your creamy binding layer.
🥘 Step 2: Assemble the Layers in a Greased Dish
Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with butter or nonstick spray—this prevents sticking and makes cleanup a breeze. Start by layering ⅓ of the potato slices in the bottom, slightly overlapping them. Pour ⅓ of the cheese mixture over the potatoes, spreading it evenly. Sprinkle with ⅓ of the crumbled 6 oz bacon for extra richness.
Repeat this process with another layer of potatoes and cheese mixture. For the final layer, arrange the remaining potato slices, then pour the last of the cheese sauce on top. Here's the thing—don't skip the final layer of sauce. It ensures every bite is creamy and prevents dry spots.
🔥 Step 3: Bake Until Bubbly and Golden
Cover the dish tightly with aluminum foil and bake for 45 minutes. This initial covered bake allows the potatoes to soften without over-browning. After 45 minutes, remove the foil and sprinkle 0.25 cup panko breadcrumbs evenly over the top. Return to the oven for 15-20 minutes until the top is golden brown and the edges bubble vigorously.
Watch for the perfect moment—the breadcrumbs should turn a deep golden color while the cheese on top turns slightly bubbly. If it's browning too quickly, tent loosely with foil for the last 5 minutes. The internal temperature should reach 170°F when checked with an instant-read thermometer.
⏰ Step 4: Rest and Garnish for Maximum Flavor
Let the scalloped potatoes rest for 10 minutes before serving—this allows the layers to set and makes slicing cleaner. The cheese will firm up slightly, and the potatoes will absorb all that creamy goodness. Garnish with 0.25 cup chopped fresh chives right before serving for a pop of color and freshness.
Slice into squares and serve immediately. The combination of creamy, tangy, and crispy elements makes this dish irresistible. Real talk: leftovers reheat beautifully—just cover with foil and warm in the oven at 350°F for 15 minutes. The texture holds up surprisingly well!
Pro Tips For Making Campbell'S Scalloped Potatoes
- SOAK THE POTATOES: Russets soak up water like sponges—drop them in cold water for 10 minutes after slicing, then pat thoroughly dry. This keeps the layers from turning soggy when the sour cream and soup mix later, especially if you’re baking at 375°F (where the cheese melts faster than you’d expect).
- STIR THE SOUP FIRST: Campbell’s soup settles like a lazy Sunday—give it a quick stir before mixing with sour cream and vinegar. I learned this the hard way when the bottom of my casserole turned into a dense, flavorless paste while the top stayed creamy. Two minutes of stirring now saves you from scraping the pan later.
- DON’T SKIP THE VINEGAR: That sharp white vinegar isn’t just for tang—it cuts through the richness of the cheese and soup, keeping the dish from tasting like a heavy, one-note hug. Use the full 1 tablespoon, even if you’re skeptical. Your taste buds will notice the difference, especially next to the sharp cheddar.
- BAKE UNTIL GOLDEN, NOT JUST BUBBLY: Pull the dish out when the top is golden-brown, not just when the cheese looks melted. The edges should be crisp enough to hold their shape, or the whole thing will slide out like a greasy blanket. If it’s not brown enough at 375°F, crank the oven to 400°F for the last 5 minutes—just watch it like a hawk.
Pro cooking tips for this dish
Layering Like a Pro
Thin, even slices are key—use a mandoline slicer for precision, but a sharp knife works too. I always soak the slices in cold water for 5 minutes to remove starch, then pat them bone-dry with paper towels. This prevents a gummy texture in the final dish.
The secret? Alternate potato layers with sauce—never let two layers of potatoes sit directly on top of each other without sauce in between. This ensures every bite is creamy, not dry. 🥔
Vinegar Balance
The ½ cup white vinegar might seem bold, but it’s what makes this dish sing. It cuts through the richness of the cheese and cream, adding brightness. If you’re worried about sharpness, start with ¼ cup and taste the sauce before baking.
I’ve tested this recipe with apple cider vinegar too—it’s slightly sweeter but works in a pinch. The vinegar also helps the cheese melt more evenly, creating that signature creamy texture. Don’t skip it!
Cheese Matters
Use freshly grated sharp cheddar—pre-shredded cheese has anti-caking agents that make the sauce grainy. I like to mix 2 cups sharp cheddar with ½ cup Gruyère for extra depth. For a smoky twist, swap in smoked Gouda.
The cheese should be room temperature when mixing into the sauce—it blends more smoothly. Sprinkle the remaining ½ cup cheese on top before baking for that golden, bubbly crust. 🧀
Bacon Boost
Crumbled 6 oz bacon adds richness and a salty crunch, but it’s optional. Cook it until crispy, then drain on paper towels to remove excess fat. Sprinkle it between layers so every bite has that smoky flavor.
No bacon? Try crumbled sausage or smoked Gouda bits for a similar effect. The key is distributing it evenly—don’t dump it all in one spot. This step elevates the dish from classic to next-level comfort food. 🥓
Crispy Top Trick
For that perfect golden crust, panko breadcrumbs are my go-to. Toss ¼ cup panko with 1 tbsp melted butter before sprinkling on top—this adds extra crispiness. If you’re short on time, crushed potato chips work just as well.
The breadcrumbs should turn deep golden brown in the last 15-20 minutes of baking. Watch closely—if it browns too fast, tent with foil to prevent burning. The result? A crispy, crunchy top that contrasts beautifully with the creamy layers below. ✨
Rest Before Serving
This is a step I see people skip, but resting for 10 minutes is crucial. It lets the layers set, making it easier to slice and preventing a runny mess. The cheese firms up slightly, and the potatoes absorb all that creamy goodness.
Garnish with chopped fresh chives right before serving for a pop of color and freshness. Trust me—this small step makes a big difference in texture and presentation. 💫

Frequently asked questions
Can I make this recipe without Campbell's cream of mushroom soup?
For a homemade version, sauté 1 cup sliced mushrooms in 2 tbsp butter until golden, then stir in 1.5 cups heavy cream and 1 tbsp flour to make a roux. Add ½ cup white wine and simmer until thickened. Use this in place of the soup in the recipe—it'll add depth and richness.
Why does my scalloped potato topping get soggy?
Soggy tops usually happen from steam buildup during baking. Always remove the foil for the last 15-20 minutes to crisp the breadcrumb topping. For extra insurance, sprinkle panko mixed with 1 tbsp cornstarch on top before baking—it absorbs moisture better. Also, make sure your oven rack is in the middle position for even heat circulation.
How can I make this dish dairy-free?
Swap the cheese for 1.5 cups dairy-free shredded cheddar (like Violife or Daiya) and use 1.5 cups full-fat coconut milk instead of sour cream. For the sauce, replace the cream of mushroom soup with 2 cups cashew cream (blend soaked cashews with water) and add 1 tbsp nutritional yeast for a cheesy flavor. The vinegar remains key for tang!
Can I prepare this ahead of time?
Yes! Assemble the dish up to 24 hours ahead and refrigerate uncovered (this prevents sogginess). Bake straight from the fridge, adding 10-15 extra minutes to the baking time. For freezing, bake completely, cool, wrap tightly in foil, and freeze for up to 3 months. Reheat covered at 350°F until bubbly. The texture holds up surprisingly well!
What's the best way to slice potatoes for even layers?
Use a mandoline slicer set to ⅛-inch thickness for perfect uniformity. For a knife method, place potatoes on a cutting board, hold the knife at a 45-degree angle, and rock gently while pulling toward you. Soak slices in cold water for 5 minutes to remove starch, then pat thoroughly dry—this prevents a gummy texture.
