FAQs

Why did my potato gratin curdle? ›

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.

If you stored the sliced potatoes in water to prevent discoloring, but didn't drain them well and pat them dry before adding them to the baking dish, you may have added extra water to the dish. You could have also used the wrong kind of potato, as some waxy potatoes can release more water than starchier potatoes.

Derived from the French verb gratiner — to broil — gratin is a process that involves topping a dish with either cheese or buttery breadcrumbs and baking or broiling until crispy. While potatoes au gratin is most traditional, the contents beneath the golden crust can vary widely.

Watery scalloped potatoes are not good, and is often caused by using the wrong type of potato. This recipe requires starchy potatoes, such as russets or Yukon golds, not waxy potatoes. Another cause is washing or holding the sliced potatoes in water (as outlined in the question above).

The Kitchn recommends whisking an egg yolk with a bit of whatever liquid you are using as the sauce's base. Gradually add your broken liquid to the egg yolk mixture, one tablespoon at a time. In doing this, you're forming a fresh emulsion. You could also add a tablespoon or so of heavy cream.

Method 3: Add starch or fat.

These ingredients not only prevent curdling, but they can fix it, too. You can heat heavy or whipping cream or make a simple roux. Gradually whisk into your curdled sauce to save it.

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.

Butter a gratin dish (which should be long and large and about 5 cm (2 in) deep) and sprinkle 2 chopped garlic slices on the bottom, a pinch of salt and pepper and more nutmeg.

The phrase au gratin literally means "by grating" in French, or "with a crust," from the verb gratter, "to scrape, scratch, or grate."

My scalloped potatoes are bland

They are also in need of serious seasoning to ensure deliciousness. Make sure your sauce is well-seasoned, but also, season each layer of potatoes with salt and pepper before adding the sauce, to make sure they are as flavorful as you want them!

What is the one trick Michael Symon uses to make perfect scalloped potatoes? ›

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.

Au gratin potatoes bake uncovered for 60 to 75 minutes.

You'll know they're done when a paring knife can be easily slipped into the center of the casserole and the top is browned and crisped. Cool the whole dish for at least 10 minutes before scooping and serving.

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.

Add more liquid

The first thing to try is adding more liquid. How much liquid to add depends on how much of the sauce is broken. If it is half-broken, add half as much again as the amount of oil that was used to break it in the first place. If it is completely broken, add equal volumes of oil and liquid.

Adjust Temperature:If curdling happens due to high heat, reduce the temperature immediately. Gradually heat the mixture over low to medium heat while stirring constantly. Avoid boiling, as this can exacerbate the issue.

Adding Liquid: If your cheese sauce has started to curdle, the first thing to do is immediately take it off the heat. Adding a splash of the sauce's base liquid, such as cold milk for a milk-based sauce, can help minimize the damage. You can also try adding a splash of wine, beer, or cream.
