Ingredients for canned potatoes scalloped
Creamy, crispy, and foolproof—this scalloped recipe turns simple canned potatoes into a luxurious dish with just 12 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Potatoes 🥔 | 2 cups | Drained, no liquid retained |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Freshly grated from block |
| Whole Milk 🥛 | ½ cup | Warmed for creaminess |
| Mustard Powder 🌶️ | 1 tsp | Key for depth of flavor |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy golden top |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crispy breadcrumb layer |
| Butter 🧈 | 2 tbsp | Unsalted, melted |
| Green Onions 🧅 | 2 whole | Sliced, for garnish |
The sharp cheddar is non-negotiable here—Kraft Natural or Cabot from the dairy aisle delivers that perfect tangy bite. For the potatoes, Libby's or Great Value brands work best—they drain evenly and hold their shape. Warm the whole milk slightly before mixing (just 30 seconds in the microwave) to help the cream sauce emulsify better. The mustard powder might seem minor, but it’s the secret to that restaurant-quality depth. Penzeys sells a great blend if you want to splurge, but the regular grocery store stuff works fine. Look for garlic powder labeled 'freshly ground'—it makes a noticeable difference.
No heavy cream? Half-and-half plus 1 tablespoon butter gets you close. Short on cheddar? Parmesan at half the amount adds umami, though it won’t melt the same way. The panko breadcrumbs are crucial for that crispy top—Japanese panko from Trader Joe's is my go-to, but any panko works. For extra richness, swap 2 tablespoons of the milk for cream cheese, blended smooth. The green onions can be omitted if you’re not a fan, but they add a nice fresh contrast. If your dish feels too thick after baking, stir in 1 tablespoon of warm milk to loosen it up.
This reheats beautifully—just cover with foil and warm at 350°F for 15 minutes. The texture actually improves the next day as the flavors meld. Store leftovers in an airtight container for up to 4 days in the fridge. For make-ahead magic, assemble the dish in a baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. The panko topping stays crispy if you bake it straight from the fridge, so no need to bring it to room temperature. Freezes well for 3 months—portion into individual servings before freezing for easy reheating.

Step-by-step instructions for canned potatoes scalloped recipe
Here's how to create a rich, creamy potato casserole with crispy edges using simple pantry staples.
Prepare the Potato Layer
Preheat your oven to 375°F. In a 9x13-inch baking dish, arrange the drained canned potatoes in a single even layer, slightly overlapping if needed. You want them to fit snugly in one layer without stacking—this ensures even baking and creamy results throughout.
Lightly brush the potatoes with 1 tablespoon of the extra-virgin olive oil using a pastry brush. This creates a subtle barrier that prevents the potatoes from absorbing too much moisture from the cream mixture later. Spread the oil evenly over all surfaces to help develop a golden crust during baking.
Create the Creamy Cheese Sauce
In a medium bowl, whisk together the 1 cup heavy cream, 0.5 cup whole milk, 1 teaspoon mustard powder, 0.5 teaspoon garlic powder, 0.5 teaspoon salt, and 0.25 teaspoon black pepper until completely smooth. The mustard powder adds depth that balances the richness of the cream.
Gradually whisk in the 1.5 cups freshly grated sharp cheddar cheese until fully melted and combined. You should have a thick, velvety sauce that coats the back of a spoon. If the cheese doesn't melt completely, warm the mixture over low heat for 1-2 minutes while stirring constantly—just enough to create a smooth, lump-free sauce.
Assemble and Bake the Scalloped Potatoes
Pour the cheese sauce evenly over the potato layer in the baking dish, spreading it with a spatula to ensure complete coverage. The sauce should reach about halfway up the potatoes—this ensures they absorb enough creaminess without becoming soggy.
Transfer the baking dish to the preheated oven and bake for 30 minutes. You'll notice the edges starting to turn golden and the cheese forming a bubbly crust. After 30 minutes, remove the dish from the oven and sprinkle the remaining 1 tablespoon extra-virgin olive oil evenly over the top.
Add the Crispy Topping
In a small bowl, combine the 0.5 cup panko breadcrumbs, 2 tablespoons melted butter, and 1 tablespoon extra-virgin olive oil (the remaining amount). Mix until the breadcrumbs are evenly coated and the mixture resembles wet sand. This topping creates the signature crispy texture that contrasts beautifully with the creamy interior.
Sprinkle the breadcrumb mixture evenly over the top of the casserole, pressing down gently with the back of a spoon to help it adhere. Return the dish to the oven and bake for an additional 15-20 minutes, or until the topping is golden brown and crispy and the cheese sauce has thickened to a custard-like consistency.
Finish and Garnish
Remove the scalloped potatoes from the oven and let them rest for 5-10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice and serve. The internal temperature should reach 160°F at the center.
Slice the green onions into thin rings and sprinkle them evenly over the top just before serving. The fresh green onions add a bright contrast to the rich, creamy potatoes. Serve immediately while the topping is still crisp and the cheese is perfectly melted—this dish doesn't reheat well once cooled.
Pro Tips For Making Canned Potatoes Scalloped
- Drain and Rinse Potatoes: Canned potatoes hold way more liquid than you think—skip the rinse at your peril. After draining, give them a quick cold-water rinse and pat dry with paper towels. This prevents a watery, soupy mess when baking, and trust me, you’ll notice the difference in texture.
- Preheat Pan to 375°F: Too low, and your scalloped potatoes steam instead of brown. Too high, and the top burns before the middle cooks. Start at 375°F for even baking, then switch to 350°F halfway through if the edges are getting too dark. (Yes, I’ve learned this the hard way.)
- Use Block Cheese, Not Shreds: Pre-shredded cheese has anti-caking agents that make your dish taste like plastic. Grate your own sharp cheddar—it melts smoother and packs more flavor. If you’re short on time, at least skip the pre-shredded stuff in the mix.
- Mix Mustard with Cream First: Sprinkling dry mustard powder over the potatoes is a recipe for uneven seasoning. Whisk it into the heavy cream and milk first so it dissolves completely. This way, every bite gets that subtle tang without clumps. (And no, you won’t taste the difference if you skip it—but you’ll miss out.)
Storing and reheating this dish
Refrigerator Storage
Store leftovers in an airtight container for up to 4 days—the flavors actually deepen overnight as the spices meld. I use glass Pyrex with snap-on lids to maintain freshness. Let the dish cool completely before sealing to prevent condensation, which can make the breadcrumb topping soggy. 🥔
Freezer-Friendly Tips
This recipe freezes beautifully for up to 3 months—portion into individual servings before freezing for easy reheating. Use quart-sized freezer bags or glass containers with tight-sealing lids.
Leave 1-inch headspace to account for expansion, and squeeze out excess air to prevent freezer burn. Label with the date to track freshness.
Oven Reheating
For best results, cover the dish with foil and reheat at 350°F for 15-20 minutes until bubbly. The oven method preserves the crispy breadcrumb topping while gently warming the creamy layers. If the top loses crispiness, broil for 1-2 minutes at the end to restore texture. 🔥
Microwave Shortcut
For a quick fix, transfer a portion to a microwave-safe dish, cover with a damp paper towel, and heat on 50% power for 2-3 minutes.
Stir halfway through to distribute heat evenly. The texture won’t be as crispy, but it’s perfect for lazy weeknights when you’re in a hurry.
Make-Ahead Magic
Assemble the dish in a baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. The cold start helps the breadcrumb topping stay crispy—no need to bring it to room temperature.
Just bake as directed, adding 5-10 extra minutes if coming straight from the fridge. ✨
Garnish Refresh
Revive reheated scalloped potatoes by topping with extra panko breadcrumbs and broiling for 2-3 minutes to restore crispiness. A sprinkle of fresh green onions or a drizzle of hot honey adds brightness to the creamy texture. Serve immediately for the best experience—the crispy topping softens quickly once sliced.
Nutrition facts
Frequently asked questions
Can I use instant potatoes instead of canned for scalloped potatoes?
Instant potatoes work perfectly—they drain and absorb flavors similarly to canned. Just follow the same layering technique and baking times. The texture will be slightly creamier since instant potatoes have more starch. For extra richness, add 1 tablespoon melted butter to the cream sauce.
Why did my scalloped potatoes turn out watery instead of creamy?
Watery results usually happen from one of two issues: too much liquid in the cream sauce or not enough baking time. Make sure to drain canned potatoes thoroughly and use 1 cup heavy cream (not milk) for proper thickness. Bake until the center reaches 160°F—the sauce will set as it cools. For extra insurance, sprinkle 1 tablespoon cornstarch mixed with 1 tablespoon cold water over the sauce before baking.
What's the best cheese substitute if I don't have sharp cheddar?
For a similar tangy flavor, try Parmesan cheese (use half the amount) or Gruyère for a nutty depth. If you prefer milder options, Monterey Jack works well but lacks the sharpness. For a dairy-free version, blend 1 cup nutritional yeast with 1 tablespoon lemon juice to mimic cheesy flavor. The key is balancing richness with acidity—mustard powder helps bridge the gap.
Can I make this recipe ahead of time for a holiday meal?
Yes! Assemble the dish completely (up to adding the breadcrumb topping) and refrigerate for up to 24 hours before baking. The cold start actually helps the breadcrumbs stay crispier. When ready to bake, add the topping and increase baking time by 5-10 minutes since it's coming from the fridge. For large gatherings, double the recipe—it reheats beautifully when covered with foil at 350°F for 15 minutes.
How do I keep the breadcrumb topping from getting soggy?
The secret is in the timing and technique. First, make sure your breadcrumbs are completely dry before mixing with butter and oil. Press them gently into the sauce (don't just sprinkle) so they make contact with the creamy layer. For extra insurance, bake the topping uncovered for the last 5 minutes to crisp it up. If reheating leftovers, broil for 1-2 minutes to restore crispiness. The key is heat exposure—keep it hot and dry!
