Potatoes Au Gratin
This is one of the best potato gratins I have ever made, and that’s saying something because I make a lot of potato gratins. Potatoes au gratin are possibly one of the top 10 comfort foods in the world. They are at the very least certainly one of the top 10 potato comfort foods in the world.
If you don’t need a gratin to serve 6, make this anyway because truly a plate of leftover gratin heated up in the microwave is one of those breakfasts worth getting up early for.
What Does au Gratin Mean?
Au gratin is a French cooking term that refers to food that is sprinkled with breadcrumbs or cheese or both and then baked or broiled until browned. For potatoes au gratin, the gratin part usually refers to cheese (scalloped potatoes are similar, but usually have no cheese), though occasionally breadcrumbs are added. If you wanted to give this casserole a final sprinkle of breadcrumbs after removing the foil halfway through the baking you could definitely do that for additional texture and even more browning.
What Kind of Cheese to Use in Potatoes au Gratin
Sometimes potato gratins are made with Gruyere or other alpine-style cheeses, but here we are leaning hard into sharp, flavorful nutty cheddar. You can use any cheddar that fits your budget, from pre-shredded bagged cheddar to some fine aged hand-grated block cheddar. You’ll really taste the cheese, so if you have a few extra bucks to throw into a dish, this would be a good place to do that.
Best Potatoes for Potatoes au Gratin
Make sure to use russet potatoes here, which have a higher level of starch, which help make the sauce creamy. They will get very tender, and fall apart a little bit as you scoop them up, but the layers will still remain distinct, and the will get very tender.

How to Prevent Potatoes au Gratin from Getting Watery
Again the russet potato is key, with the higher level of starch which will thicken the sauce.
Also, the use of higher fat cream instead of milk will help keep the sauce creamy and not watery. And make sure to bake the gratin until the potatoes are cooked to tenderness, which not only gives the gratin a creamy texture, but also ensures the potatoes absorb most of the liquid.
How to Make Potato Gratin
Preheat the oven to 400°F. Butter a 1 ½ quart baking dish, or a 9×9 inch baking pan, or spray with nonstick spray. In a medium bowl or a liquid measuring cup combine the chicken broth, cream, mustard, thyme, salt and pepper. Isn’t that a pretty mixture?
Thinly slice the potatoes, layering half of them in the prepared baking dish.
Sprinkle over half of the cheese.
Pour over half of the liquid mixture.
Repeat with the rest of the potatoes, cheese, and liquid.
Cover the pan with foil and bake for 30 minutes. Remove the foil and continue to bake for another 45 minutes or so, until the potatoes are tender (a knife slides in easily) and the top is browned and crispy. Let stand for 15 minutes before serving.
