Can I make this recipe for scalloped potatoes ahead of time?

Yes, you can assemble the entire dish and keep it in the refrigerator for up to 24 hours before baking. Just make sure the potatoes are completely covered by the sauce so they do not turn brown. When you are ready to eat, you might need to add an extra 10 to 15 minutes to the baking time since the dish will be cold when it goes into the oven.

What is the best way to slice potatoes for this dish?

A mandoline is the most effective tool for getting the thin, even slices needed for a recipe for scalloped potatoes. If you do not have one, a very sharp chef's knife will work. The goal is to keep the thickness around one-eighth of an inch. If the slices are too thick, they will take a very long time to cook and might stay firm in the center.

Why did my sauce turn out watery?

Watery sauce in a recipe for scalloped potatoes is usually caused by using low-fat milk or potatoes that do not have enough starch. It can also happen if the potatoes were very wet when you put them in the dish. Always pat your sliced potatoes dry with a paper towel before layering them to make sure you aren't adding extra moisture to the casserole.

Can I add cheese to a recipe for scalloped potatoes?

While traditional scalloped potatoes do not use cheese, many people enjoy adding a sprinkle of cheddar or parmesan between the layers. If you add a lot of cheese, the dish technically becomes "au gratin," but it will still be delicious. Just be aware that cheese adds more oil to the dish, so you might want to reduce the amount of butter in your sauce slightly.

Can I freeze scalloped potatoes?

Freezing a recipe for scalloped potatoes can be tricky because dairy-based sauces often break or become grainy when thawed. If you must freeze it, it is best to do so after the dish is fully baked and cooled. Wrap it very tightly to prevent freezer burn. When you are ready to eat it, thaw it in the fridge overnight and reheat it slowly in the oven to help the sauce come back together.
