Frequently Asked Questions
- → Is it okay to prep scalloped potatoes ahead of time?
- Absolutely! You can assemble them up to a day in advance, cover them tightly, and refrigerate. When baking from chilled, just add an extra 10 to 15 minutes to the cook time.
- → What potatoes should I pick for the best result?
- Yukon Golds are the go-to choice since they keep their shape and turn out creamy. Russets can work, but they might break apart more easily.
- → Can I make this dish without using any dairy products?
- You can! Swap dairy versions for plant-based milk, butter, and cheese to make a non-dairy alternative while keeping it still delicious.
- → How thin should the potato slices be?
- Aim for slices about 1/8-inch thick so they cook evenly. A mandoline works wonders for this, but a sharp knife will do the trick too.
- → Why did the sauce split or curdle?
- To keep the sauce smooth, don’t boil it, and make sure to use flour for thickening before adding the cheese. Freshly shredded cheese will also melt more evenly.
