Why This Recipe Saves You Money
I built this recipe to be kind to your budget. Every choice has a cost-saving reason behind it.
Sweet potatoes and yams are incredibly cheap, especially in fall. They are the star ingredient and cost pennies per serving. You use basic pantry staples for the creamy sauce. Milk, flour, and butter form the base.
You don’t need fancy cheeses. A modest amount of a basic sharp cheddar gives big flavor. The recipe also uses the whole potato. There’s no wasteful peeling if you scrub them well.
Finally, it’s a one-dish meal. You bake and serve it in the same dish. That saves you time on cleanup, which is its own kind of savings.
My Tips for Smart Shopping on a Budget
How you shop makes all the difference. These are my hard-earned tricks for keeping costs down.
Buy sweet potatoes loose from the bin, not pre-bagged. You can pick the best sizes and often get a better price. Choose smaller to medium ones. They are often sweeter and cook more evenly.

Notes
Enjoy your homemade Sweet Potato Scalloped Potatoes Recipe!
For cheese, buy a block and grate it yourself. Pre-shredded cheese costs more and has anti-caking agents. A block of sharp cheddar stretches further and melts better.
Use dried thyme if that’s what you have. Fresh herbs are lovely but not required. Dried herbs are a pantry powerhouse. Keep your milk basic. Whole milk is great, but 2% works perfectly here too.
The Budget-Friendly Ingredient List
Check your pantry first. You might already have most of this. Every item is affordable and easy to find.
- 2 ½ to 3 pounds sweet potatoes or yams (about 4-5 medium)
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 ½ cups milk (any kind you have)
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- ½ teaspoon black pepper
- 1 ½ teaspoons salt
- 1 ½ cups shredded sharp cheddar cheese, divided
How to Make It (Step-by-Step)
Follow these simple steps. The result is a creamy, layered dish with a gorgeous cheesy top. For another simple and healthy way to enjoy sweet potatoes, try this easy carrot and sweet potato soup.
1. Start by heating your oven to 375°F (190°C). Grease a 9×13 inch baking dish lightly with butter or cooking spray.
2. Scrub the sweet potatoes very well under running water. You do not need to peel them. The skins add nutrition, texture, and save you time. Slice them into ⅛-inch thick rounds. A sharp knife or mandoline works best.
3. Now, make the sauce. In a medium saucepan, melt the 3 tablespoons of butter over medium heat. Whisk in the 3 tablespoons of flour. Cook for 1 minute until it smells a bit nutty.
4. Slowly pour in the milk, whisking constantly to avoid lumps. Add the garlic powder, dried thyme, pepper, and salt. Keep whisking until the sauce thickens enough to coat the back of a spoon. This takes about 5-7 minutes.
5. Remove the sauce from the heat. Stir in 1 cup of the shredded cheddar cheese until it’s melted and smooth.
6. Arrange a third of the sweet potato slices in the bottom of your prepared dish. It’s okay if they overlap. Pour a third of the cheese sauce over this layer. Repeat this process two more times: potatoes, then sauce.
7. Sprinkle the remaining ½ cup of cheese evenly over the very top. Cover the dish tightly with aluminum foil.
8. Bake, covered, for 45 minutes. Then, remove the foil and bake for another 15-20 minutes. The top should be golden brown, and the potatoes should be tender when pierced with a fork.
9. Let the dish sit for 10 minutes before serving. This helps the sauce set so you get perfect slices.
How to Use Up Every Last Bit (No Waste!)
I hate throwing food away. Here’s how to make sure every part of this recipe gets used.
If you have leftover sauce, you can freeze it. Let it cool, then store it in a freezer bag. Thaw it in the fridge for your next pasta bake or vegetable gratin.
Extra shredded cheese? Pop it in a sealed bag in the freezer. You can sprinkle it frozen onto soups, omelets, or casseroles later.
If you end up with a few leftover cooked slices, they are a treasure. Chop them up and add them to a morning frittata or breakfast hash. They add wonderful sweetness and color.
Nutrition Notes
This dish is as nourishing as it is delicious. Here’s a simple breakdown of what you’re getting.
- Rich in Vitamin A from the sweet potatoes.
- Provides a good source of calcium from the milk and cheese.
- Contains fiber from the potato skins.
- Using the whole potato keeps the nutrients intact.
Common Questions About This Recipe
Here are answers to the questions I get asked the most about this dish.
Can I make this ahead of time?
Absolutely. Assemble the whole dish, cover it, and refrigerate it for up to 24 hours before baking. You may need to add 5-10 extra minutes to the baking time since it will be cold from the fridge.
What’s the difference between sweet potatoes and yams for this?
In most US grocery stores, the orange-fleshed tubers labeled “yams” are actually a type of sweet potato. Either will work beautifully. Just look for the ones with vibrant orange flesh for the best color and sweetness.
My sauce seems thin. Did I do something wrong?
Don’t worry. The sauce will thicken a lot as it bakes with the potatoes. It also continues to set up as the dish rests after coming out of the oven. Trust the process.
This Sweet Potato Scalloped Potatoes is proof that eating well doesn’t require a fancy budget. It’s about being smart with what you have. This savory gratin brings warmth and joy to any table, especially for a fall harvest dinner. For a heartier, protein-packed sweet potato meal, this easy ground beef and sweet potato bake is another fantastic option.
