Potatoes Au Gratin Tips
Why did my potato au gratin curdle?Curdling can occur when high heat affects the fat in dairy. In this recipe, we thicken the milk with flour to prevent curdling. Starch will also help, so make sure to use a high starch potato like a russet. If you've got leftover russet potatoes, use them up in any of these russet potato recipes!
How do you keep potatoes au gratin from becoming watery?If your au gratin is watery, replace the milk with heavy cream, which has a higher fat content, next time you prepare the recipe. Also, russet potatoes have less water and more starch, making them ideal for au gratin recipes.
What goes well with au gratin potatoes?Lemon thyme chicken is easy and delicious—and bakes at the same temperature as the potatoes! Feeling more like a steakhouse dinner? Try a garlic grilled steak or any of our other steak recipes.

Why would you cook potatoes for an hour and 40 minutes?

These are absolutely delish! I made a few slight changes the second time and since even better...switched out the milk with heavy whipping cream and used 1 1/2 cups of cheese instead and baked uncovered for 50 minutes to get the top crispier! EVERYONE asks me for this recipe now

Excellent but I think ?? half 2% and half heavy cream would of been better along with a bit of salt or some type of seasoning. But overall fantastic

this was perfect for us and exactly what I was looking for Easter - I doubled for a 9x13 pan - used cheddar/jack shredded cheese (family preference) - used 3 cups fat free milk and one cup half and half- so good!
