Ingredients for original betty crocker scalloped potato
Classic comfort starts with these 11 simple ingredients—creamy, cheesy, and nostalgic all at once.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced, peeled if preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for best creaminess |
| Whole Milk 🥛 | 1 cup | Warmed for smoother texture |
| Unsalted Butter 🧈 | 6 tbsp | Cold, cubed for even melting |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Yellow Mustard Powder 🌶️ | 1 tsp | The secret depth ingredient |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For subtle garlic flavor |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The potatoes are everything here. Russets are the gold standard—they hold their shape and soak up the sauce perfectly. Buy a few extra if you're nervous about slicing, since you'll want them paper-thin (about 1/8-inch). The sharp cheddar makes all the difference too—pre-shredded gets clumpy, so grab a block and grate it yourself. For the dairy, full-fat is non-negotiable—the creaminess comes from the fat, not the water. If you're in a pinch, Whole Foods or Kroger always have good-quality dairy, but the butter should be cold** when you cube it—this keeps the sauce from separating.
No heavy cream? Half-and-half plus a splash of milk works in a bind, but you'll lose some richness. Mustard powder can be swapped for Dijon mustard at half the amount, but it'll be more intense. The flour is just for thickening—if you're gluten-free, cornstarch works 1:1. For the garlic powder, fresh minced garlic is better but requires more effort. The parsley is totally optional, but it adds that fresh pop of color—Trader Joe's sells big bunches for cheap if you want to go overboard. And if you're worried about the sauce being too thin, just add a few more slices of potato between layers—they'll absorb the extra liquid.
This dish reheats like a dream—just cover with foil and warm at 350°F for 15-20 minutes. Leftovers keep for 3-4 days in the fridge, but honestly, it's even better the second day as the flavors meld. For make-ahead prep, assemble the dish in a baking dish, cover, and refrigerate for up to 24 hours before baking. The cheese gets extra melty that way. And if you're serving a crowd, double the recipe—it's worth it.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s literally one bowl, one pan, no fuss. Just slice those Russets thin, layer them with the creamy milk-butter mix, sprinkle in that sharp cheddar, and bake—no chopping boards to clean, no extra dishes. Honestly, the only mess is the delicious kind.
- Creamy-Cheesy Bliss: That combination of heavy cream and sharp cheddar? It’s the kind of rich, velvety goodness that makes you close your eyes halfway through the first bite.

- Budget-Friendly Luxury: Russets are cheap, milk and butter are pantry staples, and a block of cheddar stretches far. It’s one of those dishes that feels fancy without breaking the bank. Plus, the creamy sauce makes it feel indulgent, even when you’re cooking on a tight budget.
Step-by-step instructions for original Betty Crocker scalloped potato recipe
Here's how to build that iconic creamy, cheesy potato casserole layer by layer.
Prepare the Potatoes and Seasoning Base
Start by thinly slicing the 3 lb russet potatoes—about ⅛-inch thick—using a sharp mandoline or knife. You want even slices so they cook uniformly. As you slice, place them in a large bowl of cold water to prevent browning. This is key for keeping those potatoes crispy on the outside while tender inside.
In a small bowl, whisk together the 1 cup heavy cream, 1 cup whole milk, 2 tbsp all-purpose flour, 1 tsp yellow mustard powder, 0.5 tsp garlic powder, 1.5 tsp salt, and 0.5 tsp black pepper. The mustard powder adds that classic tangy depth you'd expect from Betty Crocker's original. Warm the milk separately in a small saucepan over low heat until just steaming—this helps the sauce blend smoother later. Let it cool slightly before mixing with the other ingredients.
Assemble the Layers for Maximum Creaminess
Preheat your oven to 375°F and grease a 9x13-inch baking dish with 2 tbsp of the unsalted butter, rubbing it all over the bottom and sides. This prevents sticking and adds rich flavor. Arrange a single layer of potato slices in the dish, overlapping them slightly but not too tightly—you want them to touch each other but still allow the cream to penetrate.
Sprinkle ⅓ of the shredded sharp cheddar cheese evenly over the first layer. Then, pour ⅓ of the cream mixture over the cheese. Repeat this layering process two more times, ending with a final layer of potatoes. The cheese should be distributed evenly between each layer, and the cream mixture should cover each layer completely. This ensures every bite has that signature creamy, cheesy goodness.
Add the Butter and Bake to Golden Perfection
Dot the top of the casserole with the remaining 4 tbsp unsalted butter, spreading it evenly across the surface. This creates a golden, crispy crust while keeping the inside creamy. Cover the dish tightly with aluminum foil and bake for 45 minutes. The foil traps steam, helping the potatoes cook through without drying out.
After 45 minutes, remove the foil and bake for another 15-20 minutes until the top is golden brown and bubbly. You'll see the cheese turning a lovely golden hue—this is your signal it's ready. If the edges brown too quickly, tent them loosely with foil to prevent over-browning while the center finishes cooking.
Rest and Garnish for the Ultimate Presentation
Let the scalloped potatoes rest for 10 minutes before serving. This resting period allows the juices to redistribute, ensuring each slice is creamy and not runny. The dish should be bubbling hot and the potatoes fork-tender with a slight bite. If you're serving it immediately, sprinkle the 0.25 cup chopped fresh parsley over the top for a pop of color and freshness.
Slice into 6 equal portions and serve warm. The layers should be distinct—creamy sauce, tender potatoes, and melty cheese in every bite. This is the classic comfort food you remember, made even better with a few modern tweaks to keep it foolproof. Enjoy it with a simple green salad or crusty bread to soak up every last bit of that creamy goodness.

Storing and reheating your original betty crocker scalloped potato
Refrigerator Storage
Store leftovers in an airtight container with a tight-fitting lid to maintain moisture and prevent drying. I use glass Pyrex containers because they distribute heat evenly when reheating.
Keep the dish at 40°F or below for up to 4 days—the flavors actually deepen as the sauce melds with the potatoes. The key is to let it cool completely before sealing to avoid condensation buildup, which can make the potatoes soggy. 🥔
Freezer Prep Tips
For longer storage, assemble the dish in a 9x13-inch baking dish, cover tightly with aluminum foil, then wrap the dish in plastic wrap for extra protection. Freeze for up to 3 months—the butter and cheese maintain their texture surprisingly well.
When ready to eat, thaw overnight in the fridge before reheating. I like to portion individual servings into freezer-safe containers for easy grab-and-go meals. 🧊
Oven Reheating Method
This is my preferred way to revive scalloped potatoes—it restores that creamy texture perfectly. Cover the dish with foil and bake at 350°F for 15-20 minutes, adding 2-3 tablespoons of milk or water if the sauce looks dry.
For even better results, place a small cup of water in the oven alongside the dish to add moisture to the air. The internal temperature should reach 165°F for food safety. 🔥
Microwave Shortcut
When I'm short on time, I use the microwave for quick reheating. Cover the potatoes with a damp paper towel and microwave on 50% power for 2-3 minutes, stirring halfway. This prevents overheating the edges while warming the center.
Add a splash of milk if the sauce separates—just 1 tablespoon is enough to restore creaminess. For best texture, avoid microwaving from frozen. ⚡
Make-Ahead Baking Hack
Assemble the dish completely, cover tightly, and refrigerate for up to 24 hours before baking. The cold start helps the cheese melt more evenly and creates a thicker sauce. When baking, you may need 5-10 extra minutes at the end to compensate for the cold start.
I also like to add an extra 1 tablespoon of butter to the top layer before baking—it creates that perfect golden crust while reheating. 💡
Serving Leftovers Creatively
Turn reheated scalloped potatoes into potato pancakes by slicing and pan-frying in butter until crispy. Or make potato croquettes by mixing with breadcrumbs and frying. For a quick breakfast, top with a fried egg and hot sauce.
The possibilities are endless—just remember that reheated scalloped potatoes taste best when served with crusty bread or a simple green salad to cut through the richness. 🍳

Frequently asked questions
Why does the original Betty Crocker recipe use mustard powder?
The mustard powder adds a subtle tang that balances the richness of the cheese and cream. It was a classic touch in vintage recipes to prevent the dish from tasting too heavy. You can substitute it with ½ teaspoon Dijon mustard if you prefer a more pronounced flavor, but reduce the amount since it's stronger.
Can I make this recipe with waxy potatoes like Yukon Gold?
Waxy potatoes like Yukon Gold won't hold their shape as well as Russets and may turn mushy. For best results, stick with Russets or Idaho potatoes—they absorb the cream while staying firm. If you must use Yukon Gold, slice them slightly thicker (¼-inch) and reduce baking time by 5-10 minutes to prevent overcooking.
What's the secret to preventing a watery sauce?
The key is proper layering and baking technique. Use 3 layers max of potatoes, and don't overfill the baking dish—it should be ¾ full when assembled. Also, let the potatoes drain in cold water before layering to remove excess starch. If your sauce still looks thin after baking, sprinkle 1 tablespoon flour over the top before the final baking phase.
How can I make this dish dairy-free?
Swap the heavy cream for full-fat coconut milk and whole milk for unsweetened almond milk. Use dairy-free cheddar shreds (like Violife or Daiya) and add 1 tablespoon nutritional yeast for a cheesy flavor. The texture will be slightly lighter, but still creamy. For extra richness, stir in 2 tablespoons melted coconut oil into the sauce mixture.
Why did my top layer get too brown before the center cooked?
This happens when the oven runs hot or the dish is uncovered too early. For even browning, tent the edges with foil after 30 minutes of baking, then uncover just the center for the final 10 minutes. If your oven runs hot, reduce the temperature to 350°F for the last 15 minutes to finish cooking gently.
