Scalloped Potatoes Recipe (2024)

FAQs

What is the difference between scalloped potatoes and au gratin potatoes? ›

The difference comes down to cheese. Scalloped potato recipes are usually baked in a basic cream sauce until soft and tender, with no cheese topping. Potatoes au gratin are a bit more decadent. They are made with lots of cheese sprinkled in between the layers of potatoes and also on top of the casserole.

Potatoes or rice can remain rock-hard after prolonged cooking. Starch will not swell if it is acidic. If you have a lot of sour cream in your scalloped potatoes or add something acidic, your potatoes may not soften. You can cook the potatoes with heavy cream or milk and then, after they soften, stir in sour cream.

Once you've chosen the right potatoes, grab a sharp chef's knife (or a mandoline, if you have one) and carefully slice them as thinly and evenly as possible—ideally one-fourth to one-eighth-inch thick. Potatoes that are too thick or thin will bake up unevenly, and you want the layers to cook up tender.

The curdling is caused by high heat, which is hard to avoid in an oven. So to keep the sauce together, tackle it before the dish goes in the oven. Instead of simply layering grated cheese and milk or cream with the potatoes, you need to make a smooth cheese sauce.

My sauce is watery

If you stored your potatoes in water to prevent discoloring, be sure to drain them well and pat them dry before adding to your casserole. Some of the waxier potatoes can release more water than starchier ones, so look for good baking potatoes like russet or Yukon golds.

Surprisingly, aluminum foil is his secret weapon. After beautifully shingling the potatoes (he's got a genius trick for doing this quickly, too) he covers the dish in foil before hitting the oven.

Do I have to blanch my potatoes, to make scalloped potatoes ahead of time? A: The short answer I recommend is yes, almost always. If sliced and then placed into a pot of cold water, bring to a boil for 1-2 minutes till the slices have a rubbery consistency, this blanching will help stop the oxidation process.

runny scalloped potatoes. If you find yourself faced with a soupy pan of potatoes, shake a few tablespoons of flakes into the sauce and mix them around with a fork or a small whisk. The flakes will soak up the extra liquid in a flash, and you can keep adding them until the sauce is at the proper thickness.

This process, which is called oxidation, happens because potatoes are a naturally starchy vegetable. And when exposed to oxygen, starches turn gray, brown, or even black. An oxidized potato is completely safe to eat. The process doesn't affect the flavor or texture of the vegetable.

before cooking?" The answer is most definitely YES!

Do you need a mandoline for scalloped potatoes? ›

You could use a mandoline slicer for this step, but I actually prefer to do it with a knife. Just be careful to slice the potatoes thinly and evenly so that they cook through at the same rate. Next, make the sauce. Melt the butter in a medium skillet, and then sprinkle in the flour and whisk to make a roux.

To further lower the risk of curdling, you can add extra starch in the form of flour or cornstarch. Just a teaspoon or two is enough to stabilize the dairy, as well as to give you a lusciously thick sauce. Of course, another highly important ingredient is cheese.

Make-Ahead Option #1: Prepare the sauce and potatoes, add to the casserole dish, then wrap tightly with plastic wrap or foil and refrigerate. This can be done up to two days in advance. When you're ready to cook, sprinkle the cheese on top and bake as directed.

They will be fully cooked when you can easily pierce them with a sharp knife or mush with the tines of a fork. I usually pull out a slice when I think they are done (typically 15-20 minutes) and let it cool enough to taste.

The dehydrated potatoes may soak up a little more liquid than fresh potatoes, so it's best to rehydrate them a little before using with fresh sauce. Simply cover with hot water for 15 minutes, drain and use as indicated in your recipe.

Rub the skin with vegetable oil. Sprinkle with salt. Pierce the skin of the potato in several places with the tines of a fork. Place on a cookie sheet and bake for 1 hour and 15 minutes, until the sides are soft when pressed.

The best way to prevent curdling in scalloped potatoes is to start with high starch potatoes, such as Russets, that will help to thicken the sauce, use very fresh cream or half-and-half rather than whole or low-fat milk, and thicken the cream with flour or corn starch to make a sauce rather than topping the ingredients ...
