Scalloped potatoes are a classic comfort food dish that is perfect for any occasion. Whether you’re serving it as a side dish for a holiday meal or as a main course for a weeknight dinner, scalloped potatoes are sure to be a hit. However, one of the most common questions people have when it comes to cooking scalloped potatoes is how long to cook them. In this article, we’ll explore the answer to this question and provide you with a step-by-step guide on how to cook the perfect scalloped potatoes.
Understanding the Basics of Scalloped Potatoes
Before we dive into the cooking time, let’s first understand the basics of scalloped potatoes. Scalloped potatoes are a dish made from thinly sliced potatoes, cream, cheese, and seasonings. The potatoes are layered in a baking dish and topped with a creamy sauce and cheese. The dish is then baked in the oven until the potatoes are tender and the top is golden brown.
The Importance of Thinly Sliced Potatoes
One of the key factors in cooking scalloped potatoes is the thickness of the potato slices. Thinly sliced potatoes are essential for achieving the right texture and cooking time. If the potatoes are too thick, they may not cook evenly, and the dish may end up being undercooked or overcooked.
Tips for Slicing Potatoes Thinly
To slice potatoes thinly, you can use a mandoline or a sharp knife. Here are a few tips to help you slice potatoes thinly:
- Use a mandoline with a adjustable blade to get the perfect thickness.
- Slice the potatoes when they are cold, as this will help them to slice more evenly.
- Slice the potatoes in a gentle, sawing motion, applying gentle pressure.
Cooking Time for Scalloped Potatoes
Now that we’ve covered the basics of scalloped potatoes, let’s talk about the cooking time. The cooking time for scalloped potatoes will depend on several factors, including the thickness of the potato slices, the temperature of the oven, and the size of the baking dish.
Cooking Time for Thinly Sliced Potatoes
For thinly sliced potatoes, the cooking time will typically be around 30-40 minutes. However, this can vary depending on the temperature of the oven and the size of the baking dish. Here are some general guidelines for cooking thinly sliced potatoes:

What are the essential ingredients for making scalloped potatoes?
The essential ingredients for making scalloped potatoes include thinly sliced potatoes, onions, butter, all-purpose flour, milk or cream, grated cheese (such as cheddar or mozzarella), salt, and pepper. You may also choose to add additional ingredients, such as diced ham or bacon, to give the dish extra flavor.
It’s worth noting that the quality of the ingredients can greatly impact the final result. Choose high-quality potatoes that are high in starch, such as Russet or Idaho potatoes, for the fluffiest results. Freshly grated cheese will also melt more smoothly and evenly than pre-shredded cheese.
How do I slice the potatoes for scalloped potatoes?
To slice the potatoes for scalloped potatoes, use a mandoline or sharp knife to slice them into very thin rounds, about 1/8 inch thick. Try to make the slices as uniform as possible so that they cook evenly. You can also use a food processor with a slicing attachment to slice the potatoes quickly and evenly.
It’s also a good idea to slice the potatoes just before assembling the dish, as sliced potatoes can turn brown quickly due to oxidation. To prevent this, you can soak the sliced potatoes in cold water for about 30 minutes before assembling the dish.
How do I prevent the potatoes from turning brown during cooking?
To prevent the potatoes from turning brown during cooking, make sure to slice them just before assembling the dish, and soak them in cold water for about 30 minutes if you’re not using them right away. You can also add a splash of lemon juice or vinegar to the water to help prevent browning.
Additionally, make sure to cook the potatoes in a hot oven, as high heat will help to cook the potatoes quickly and prevent browning. You can also cover the dish with foil for part of the cooking time to prevent the top layer of potatoes from browning too quickly.
Can I make scalloped potatoes ahead of time?
Yes, you can make scalloped potatoes ahead of time, but it’s best to assemble the dish just before baking. You can slice the potatoes and onions, and grate the cheese, up to a day in advance, but it’s best to assemble the dish just before baking to prevent the potatoes from becoming soggy.
If you do need to make the dish ahead of time, you can assemble it up to a few hours in advance and refrigerate it until you’re ready to bake. Just be sure to let it come to room temperature before baking to ensure even cooking.
How do I know when the scalloped potatoes are done?
The scalloped potatoes are done when they’re golden brown on top and the potatoes are tender and cooked through. You can check for doneness by inserting a fork or knife into the potatoes – if it slides in easily, they’re done.
You can also check the internal temperature of the potatoes – they should be cooked to an internal temperature of at least 190°F (88°C). If you’re unsure, it’s always better to err on the side of caution and cook the potatoes for a few more minutes to ensure they’re cooked through.
Can I make scalloped potatoes in a slow cooker?
Yes, you can make scalloped potatoes in a slow cooker. Simply assemble the dish as you would for the oven, but instead of baking, cook it on low in the slow cooker for 3-4 hours. This is a great option if you want to come home to a hot, ready-to-eat meal.
Keep in mind that the results may be slightly different than oven-baked scalloped potatoes – the potatoes may be more tender and the top may not be as crispy. However, the slow cooker method can still produce delicious results with minimal effort.
How do I store leftover scalloped potatoes?
Leftover scalloped potatoes can be stored in the refrigerator for up to 3 days or frozen for up to 2 months. To refrigerate, let the potatoes cool completely, then cover them with plastic wrap or aluminum foil and refrigerate.
To freeze, let the potatoes cool completely, then transfer them to an airtight container or freezer bag. When you’re ready to reheat, thaw the potatoes overnight in the refrigerator, then reheat them in the oven or microwave until hot and bubbly.
