What is the baking time for scalloped potatoes?

How can I tell when the scalloped potatoes are done?

The scalloped potatoes are done when they are tender and easily pierced with a fork, and the top is golden brown and bubbly. You can also check if the potatoes feel tender throughout by inserting a knife.

Can I make scalloped potatoes ahead of time?

Yes, you can prepare the scalloped potatoes ahead of time by assembling the layers and covering the baking dish with plastic wrap or aluminum foil. Store it in the refrigerator and bake it when ready, adding an extra 10-15 minutes to the baking time if baking straight from the fridge.

What can I use instead of milk in scalloped potatoes?

A 9x13 inch baking dish is ideal for layering the potatoes and sauce. If you have a larger quantity or prefer thicker layers, you can use a slightly deeper dish.

Cooking Tips:

- Ensure the potatoes are sliced thinly and evenly to promote even cooking and ensure a uniform texture.

- For added flavor, consider incorporating a bit of cheese between the layers of potatoes.

- Use a mandoline slicer to make the potato slices more uniform if you have one available.

- Feel free to add other herbs or spices to suit your taste, such as thyme or rosemary.

- Let the dish sit for about 10 minutes after baking before serving. This allows the sauce to set slightly, making it easier to serve.
