Ingredients for scalloped potatoes with half and half
Half and half and cheddar make these scalloped potatoes restaurant-worthy in one baking dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 ½ lb | Thinly sliced, peeled preferred |
| Half and Half Cream 🥛 | 2 cups | Full-fat for best creaminess |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Freshly grated, block preferred |
| Heavy Cream 🥛 | ½ cup | Optional for extra richness |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Garlic Cloves 🧄 | 4 cloves | Minced for flavor depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme leaves |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Gruyère Cheese 🧀 | ½ cup | Optional for nutty flavor |
| Breadcrumbs 🍞 | ¼ cup | Panko for extra crunch |
The potatoes are the star, so pick firm, starchy russets—they hold up best to slicing and baking. Costco sells them in bulk for great prices, but any grocery store's russets work. Peeled or unpeeled? I peel mine (easier to slice evenly), but the skin adds texture if you leave it. For the cheese, sharp white cheddar is non-negotiable—it melts perfectly and has that tangy kick. If you're feeling fancy, add Gruyère for nutty depth. The half and half? Store-brand works fine, but organic or grass-fed has richer flavor. Don't use light cream—this dish needs that velvety richness!
No half and half? Whole milk plus a splash of heavy cream gets you close, but the texture won't be quite as luxurious. Fresh thyme is ideal, but dried works at half the amount. The flour is just for thickening—don't skip it, or the sauce will be too thin. For extra crispy edges, toss the sliced potatoes in a little flour before layering. The breadcrumbs on top? Panko gives the best crunch, but regular breadcrumbs work too. Want to make it ahead? Assemble the dish, cover, and refrigerate overnight—it'll be even creamier when baked!
This reheats like a dream—just cover with foil and warm in the oven for 15-20 minutes. Leftovers keep for 4-5 days in the fridge, but honestly, it disappears that fast. For meal prep, bake in a 9x13 dish so you can portion easily. Freezes beautifully too—just reheat covered with foil first to melt the cheese, then uncover to crisp the top. The best part? The sauce gets even richer the next day, so always make extra. Trust me on this one—it's the kind of dish that gets rave reviews every single time!

Step-by-step instructions for scalloped potatoes with half and half
Here's how to create layers of velvety, golden perfection that'll disappear faster than you can say "half and half."
Prepare the Potatoes for Perfect Layers
Start by peeling the 2.5 lb russet potatoes and slicing them paper-thin—about ⅛-inch thick—using a mandoline or sharp knife. I like to keep them uniform so they cook evenly. Soak the slices in cold water for 10 minutes to remove excess starch, then drain and pat completely dry with paper towels. This step is crucial—wet potatoes steam instead of crisping, and we want that beautiful golden crust.
Preheat your oven to 375°F while you work. The potatoes need to go into a hot oven right away to start cooking immediately. Arrange half the potato slices in a single layer in a 9x13-inch baking dish, slightly overlapping them. The dish should be large enough to accommodate all layers without crowding.
Build the Creamy Cheese Layers
In a medium bowl, whisk together the 2 cups half and half cream, 0.5 cup heavy cream, 2 tbsp all-purpose flour, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp dried thyme until smooth. This mixture is the heart of your creamy sauce—don't skip the flour, as it helps thicken the sauce beautifully. Stir in 2 cups freshly grated sharp white cheddar cheese and 0.5 cup grated gruyère cheese until fully combined. The cheeses should melt smoothly into the cream.
Pour half of this creamy mixture evenly over the potato layer in your baking dish. Sprinkle half of the 0.25 cup breadcrumbs over the cream. The breadcrumbs add a delightful crunch that contrasts perfectly with the creamy layers. Repeat with the remaining potato slices, cream mixture, and breadcrumbs, ending with a final layer of breadcrumbs on top.
Bake Until Golden and Bubbly
Place the baking dish on the middle rack of your preheated oven and bake for 45 minutes. After 30 minutes, tent the dish loosely with aluminum foil to prevent the top from browning too quickly. You're looking for a golden brown crust on top and bubbling edges—this indicates the cream is thickening perfectly. If the top isn't browning enough, uncover it for the last 10 minutes of baking.
Here's the thing—don't overbake! The potatoes should be tender when pierced with a fork, but still hold their shape. If the sauce looks too thick, it's better to let it sit for a few minutes before serving—it will continue thickening as it cools slightly. The internal temperature should reach 175°F when checked with an instant-read thermometer.
Rest and Serve Warm
Remove the dish from the oven and let it rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice cleanly. The potatoes should be fork-tender with a creamy, cheesy sauce that clings to every bite. If you're feeling fancy, broil for 1-2 minutes at the end to get an extra-crispy top, but watch it closely—broiling can burn quickly.
Serve immediately with a simple side salad or steamed green beans. The contrast of the warm, creamy potatoes with cool, fresh greens is incredible. Each bite should deliver that perfect balance of crispy edges, creamy sauce, and tender potatoes—this is what makes these scalloped potatoes truly special.
Pro Tips For Making Scalloped Potatoes With Half And Half
- PRE-COOK POTATOES FIRST: I learned this the hard way—raw potato slices in the oven turn to glue. Parboil them 5-7 minutes until just fork-tender, then drain well. This keeps slices intact and soaks up that creamy half-and-half mix instead of turning into a sad, mushy mess.
- SALT THE CREAM MIX: That sharp cheddar needs a partner in crime. Stir in ½ teaspoon salt to your half-and-half/heavy cream combo before layering—it balances the cheese’s bite and makes the whole dish taste richer. (Yes, even if the cheese is already "sharp.")
- DON’T SKIP THE BUTTER LAYER: Slather the bottom of your dish with melted butter before adding potatoes—it’s the non-negotiable crust-maker. For extra insurance, dot the top of the final cheese layer with a pat of cold butter before baking. The top will brown like a dream.
- BAKE LOW AND SLOW: After 30 minutes at 375°F, drop the heat to 350°F and cover with foil. This prevents the top from burning while the middle finishes cooking—no more dry, overbrowned tops or raw centers. (I know, I know, but trust the process.)
Pro cooking tips for this recipe
Layering Like a Pro
Uniformity is key for even cooking—slice potatoes to a consistent ⅛-inch thickness using a mandoline slicer (like the OXO Good Grips). Soak slices in cold water for 10 minutes to remove starch, then pat completely dry with paper towels.
This prevents soggy layers and ensures crispy edges. I arrange slices in a single overlapping layer in my 9x13-inch baking dish before adding cream—this creates the perfect foundation for that golden crust. 🥔
Cream Sauce Secrets
The half and half needs to be full-fat for that signature velvety texture—never substitute with light cream. Whisk in the 2 tbsp flour first to create a smooth roux before adding cheeses. For extra richness, I melt ½ cup butter alongside the garlic—this adds depth without overpowering.
The secret to avoiding lumps? Temper the cheeses by gradually mixing them into the warm cream. Stir in the breadcrumbs last to keep them crispy. 🧈
Baking Time Mastery
Bake at 375°F for 45 minutes total, but tent with foil after 30 minutes to prevent over-browning. The sauce should be bubbly with a golden crust—this means it's thickening perfectly. For extra crispiness, broil for 1-2 minutes at the end, but watch closely to avoid burning.
I check doneness with an instant-read thermometer at 175°F internal temp. Overbaking turns potatoes gummy, so pull them out when they're just tender. ⏱️
Resting for Perfection
Never skip the 10-minute rest after baking—this lets the layers set and the sauce thicken further. The potatoes will hold their shape better and slice cleanly. For serving, I like to add a final sprinkle of fresh thyme leaves or black pepper right before plating.
The contrast of warm, creamy potatoes with cool garnishes makes every bite feel special. Trust me, this resting step is what transforms good into restaurant-quality. ✨
Equipment Upgrades
Invest in a good baking dish—I use Ceramic CorningWare for even heat distribution. A mandoline slicer makes potato prep a breeze, but a sharp knife works too if you take your time. For crispy edges, I brush the baking dish with a little butter before adding potatoes.
And always use freshly grated cheese—pre-shredded contains anti-caking agents that make the sauce grainy. These small upgrades make all the difference! 🔥

Frequently asked questions
Can I make this recipe without half and half?
The half and half is what gives these potatoes their signature velvety texture, but you can substitute with 1½ cups whole milk + ½ cup heavy cream for a similar richness. For extra creaminess, whisk in 1 tbsp cornstarch to help thicken the sauce. The flavor won't be identical, but it'll still be delicious!
How do I prevent the top from getting too brown before the potatoes are done?
Tent the dish loosely with aluminum foil after 30 minutes of baking to slow browning while the potatoes cook through. For extra insurance, bake at 350°F instead of 375°F—it takes slightly longer but gives more even cooking. The key is golden-brown, not burnt!
What's the best way to reheat leftovers?
Cover with foil and warm in a 350°F oven for 15-20 minutes until heated through. For extra crispiness, broil for 1-2 minutes at the end. Microwaving works in a pinch, but it can make the sauce watery. The good news? These reheat beautifully—often better the second day!
Can I make this dish ahead of time?
Assemble the dish, cover tightly, and refrigerate for up to 24 hours before baking. The flavors meld beautifully overnight, and it bakes even more creamy. For make-ahead meals, bake it 1 hour before serving so it has time to rest and set properly.
Why did my sauce turn out too thick?
This usually happens if the cream mixture wasn't warmed enough before baking. The sauce should be pourable but slightly thickened when poured over the potatoes. For next time, whisk the cream and cheese together over low heat for 2-3 minutes before assembling. Also, avoid overbaking—the sauce thickens more as it cools.
