Vegan Potatoes Au Gratin Recipe (2024)

FAQs

Why are my au gratin potatoes watery? ›

If you used a pre-prepped potato from the refrigerator section instead of slicing your own, they can have preservatives that make them a bit 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.

Scalloped potatoes also won't be as crispy in texture as au gratin. Both are golden brown and creamy, but if it's crispiness and crunchiness you're after, au gratin will probably be your best bet. Either one is sure to be a hit with your dinner guests, but it just depends on what sort of vibe you're going for!

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.

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.

To thicken scalloped potatoes, keep cooking the sauce a minute or so longer than directed before adding the cheese. This will create a rich, extra-thick sauce. You can also use whole or 2% milk in place of the fat-free milk.

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.

I love cooking these potatoes in a cast-iron skillet because it gives the potatoes a nice crispy edge and it makes the perfect amount of potatoes.

High heat will cause the milk to curdle. Use milk or cream with higher fat content. Whole milk, half-and-half, or cream and full-fat cheeses are necessary. Skim milk and reduced-fat products will not be your friend in this dish.

Au Gratin potatoes are rich. Serve them with leaner proteins such as beef tenderloin, grilled or roasted chicken, and pan-seared fish. Another excellent pairing for Au Gratin potatoes is a fresh salad with herbs and a tart vinaigrette. Au Gratin potatoes make a great casserole and are a great entrée themselves.

What is the difference between au gratin potatoes and scalloped potatoes? Au Gratin potatoes contain cheese, whereas Scalloped Potatoes do not. Scalloped potatoes typically contain cream but can also contain flavorful stock instead of dairy.

Can I slice potatoes ahead of time for gratin? ›

If you're here, you'll probably be glad to know that yes, you can peel and cut potatoes the day before you plan to serve them — and that it's super easy! All you have to do is submerge the bare potato pieces in water and refrigerate (more on that later).

Culinary school taught me that leftovers should be eaten within two days, but if I cooked the meal, cooled the leftovers appropriately, and reheated appropriately: I'll eat leftovers for up to 5 days.

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.

It is possible to pre-prepare the gratin up to 2 days ahead by simmering the potatoes and transferring them to the buttered baking dish, then refrigerating them until needed. You should cool and refrigerate the mixture as quickly as possible, and within 2 hours of cooking.

Whisk a little cornstarch into the warm potatoes, only a teaspoon at a time, until the potatoes thicken to your liking. The potatoes must be warm. You can also use tapioca starch or potato starch, although most cooks are less likely to have those products on hand.

You can use what you have on hand: Flour, cornstarch, or powdered milk are all solid options that are probably already in your pantry. Potato flour and potato starch would work as well. Stir in the thickening agent gradually, about a tablespoon at a time, until the potatoes have reached your desired consistency.

Soil or dirt has a lot to do with the solids content of the harvested potato. Potatoes grown in clay or very dense soil have a tendency to not be able to get rid of the moisture versus potatoes grown in sandy soil or volcanic soil; which is what Idaho soil is.
