Cheese for Potatoes au Gratin
What is the best cheese for potatoes au gratin? When making Gratin potatoes, choose cheeses that have lots of bold flavors. Our top choices are varieties with a sharper flavor such as sharp cheddar, parmesan, and/or Gruyere (or swiss). Gruyere cheese adds a rich flavor to au gratin potatoes that truly cannot be matched; if you can get it, I highly recommend that you do! If Gruyere isn’t available use provolone or swiss for a similar flavor!
In the case of this recipe, the difference is the cheese. That being said, the term scalloped potatoes is still often still used if there is cheese within the dish!
How to make Potatoes Au Gratin
Potatoes Au Gratin has tender potatoes in a creamy, cheesy sauce for a dish that everyone loves.
- Prepare potatoes and onions by thinly slicing. For even thin slices, I use an inexpensive mandoline. You can find them for under $20 it and saves a lot of time.
- Make the cheese sauce per the recipe below with flour and butter. Add in a little bit of milk to make a white sauce and finally lots of cheese. If desired other additions such as garlic and fresh thyme or herbs can be added.
- Assemble the gratin. Stack the potato slices and onions in little piles and then stand them on their sides in your casserole dish (instead of laying them flat like a traditional gratin). This is easy to do and makes this potatoes au gratin recipe really pretty! It adds both extra flavor and texture with the crispy edges on the potatoes (and who doesn’t love the crispy yummy cheesy bits)!! Sprinkle a little bit of extra cheese on top if desired. Bake these Potatoes Au Gratin for about 90 minutes and garnish with parsley.
Time Saving Tip
If you’re a little short on time, set the potatoes and onions in the dish as directed and cover with plastic wrap. Microwave on full power for about 10 minutes (be careful, it will be hot when removing the plastic wrap). Add the cheese sauce and bake as directed below for about 45-55 minutes. Equally delicious… just a little bit quicker!
