Au Gratin Potatoes

Cheesy potatoes are one of those comforting side dishes that I could eat just about every day. I always think they take longer than they actually do to make. I mean, they do take an hour to bake, but that is hands off time. I can normally have this cheesy potato recipe in the oven with only a 20 minute prep.

Potatoes Au Gratin go with just about any main dish that you can imagine, making them extremely versatile.

What is the difference between potatoes au gratin and scalloped potatoes?

The main difference between au gratin potatoes and scalloped potatoes are the addition of cheese. Potatoes au gratin usually have Gruyere cheese. This cheese can sometimes be expensive and hard to find, so we often use cheddar cheese as a substitute. Sometimes au gratin potatoes are topped with bread crumbs, but the key is that lightly browned cheese that tops them.

You can also make “au gratin” recipes with vegetables other than potatoes. Think broccoli au gratin, carrots au gratin….you get it. Just add cheese and breadcrumbs if you’d like.

How do you make potatoes au gratin?

Potatoes au gratin are easier than you think!

  1. Prepare the white sauce. This is a basic homemade white sauce of butter, flour and milk. You can use a lower fat milk if you’d like, but whole milk or half and half will produce the creamiest, richest results. Add in the cheese after the sauce has thickened. Turn off the stove heat and simply stir it in. It won’t take long at all for it to melt!
  2. Slice the potatoes. Au Gratin potatoes are generally thinly sliced. You can peel the potatoes, or if you’re lazy like I am, leave them on.
  3. Layer half of the potatoes, chopped onion and half of the cheese sauce in a baking dish. Then add the rest of the potatoes and cheese sauce.
  4. Cover the dish and bake it for 40 minutes. Then remove the cover, sprinkle with remaining cheese and bake again until the potatoes are soft and the top is golden brown. It will take about 15 minutes or so.

What is the best type of potato to use for au gratin potatoes?

Use Russets or Yukon Gold potatoes for au gratin or scalloped potatoes. They are both a high-starch potato and will hold their shape well while cooking.
