I know if you are like me, often we can reach for a box of potatoes, but I promise real ones always taste better. My easy potato gratin recipe isn’t complicated and can be put together fairly quickly. While the potatoes are baking in the oven you are free to get the rest of your meal ready, or if you put this in the oven along with a chicken, both will be ready at about the same time. I love to put a couple of items in the oven at once. Cooking in the oven is often carefree cooking.

Cooking tips for easy potato gratin recipe

For this recipe I suggest using either Russet or Yukon gold potatoes. The Russets are my personal choice for this recipe, they have lots of starch in them, and that starch really helps the casserole to hold together well. I also suggest that you cut the potatoes in about 1/8 to 1/4 inch thick. You don’t want them any thicker, and slicing them any thinner will have the potatoes cooking too quickly, and then breaking apart in your dish.

In this recipe I am using heavy cream, I think that it gives these potatoes a nice richness. Heavy cream has multiple names. It can be called heavy cream, whipping cream, or even double cream. Do not substitute for whole milk. I don’t like using half and half for this recipe either. One big plus in cooking with heavy cream is that the dish will reheat better. I often really consider how the food will out the second time you enjoy this easy potato gratin recipe.

When I make this I like to use Jarlsburg cheese, if you don’t have Jarlsburg you can use a Swiss cheese, or even cheddar. My suggestion is that you grate the cheese yourself. Cheese that comes already grated has an anti caking agent on it to keep it separated in the package and I don’t think it melts as well.
