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.

Can I do everything but the baking the day before or will that screw up cheese?

This is a great recipe that can be tweaked for your personal taste. I have altered the cheeses and generally add paprika on top.

I used a 30 oz bag of hashbrowns, doubled the sauce, don't use more than 1 1/2 tp salt for doubled sauce recipe. Super simple and oh so good!!!!

Outstanding! I halved this recipe but otherwise stuck to the ingredients and directions. Came out great. I was amazed how such basic ingredients like this could come together so nicely. Highly recommend this!!

Super easy and oh so delish! If you are pressed for time but need a great side dish try semi boiling your potatoes while making your sauce. Cuts the time down significantly. Also, you can boil your potatoes in chicken broth for extra flavor!

Wonderful. This is the same recipe that my mom and I would make. But we would add pan fried pork chops to it. I would also make a toss green salad to go along with it. YUMMY.

So easy and the flavors blended just perfectly. I wouldn't change a thing and I'll make this again and again.
