Cheesy au gratin potatoes baked to perfection with smoked paprika, thyme, dry mustard, and garlic in a creamy cheddar and Parmesan cheese sauce.
For the love of cheese and potatoes, this recipe is to die for! I love the thin slices of potatoes with cheese, almost more than diced potatoes. And the seasonings make it taste so delicious.
Not only was it easier to prepare than diced (using a slicer saves a lot of time!), but I also prefer the potato-to-cheese ratio more.

Scalloped Potatoes vs Au Gratin
They both look so similar. Both have thin coins of potatoes. Both have a creamy sauce. Trying to find a difference is hard because we’ve all seen cheese in both dishes.
After researching, all I could find was that au gratin potatoes, which originated in France, often have breadcrumbs and cheese.
While scalloped potatoes, which are thought to have been created in England, have a creamy sauce with no cheese.
Ultimately, if you search, you will find cheese in both dishes. Either way, they’re delicious and will all be gone!
Can you freeze potatoes au gratin?
Yes, but like all potatoes, it’s best to cook them first prior to freezing. Raw potatoes simply don’t hold up in the freezer and turn to mush when they thaw.
I recommend partially baking the dish first so that when you do go to heat it later it doesn’t overcook the dish.
Bake it at 400 degrees Fahrenheit for 40 minutes, then cover it airtight (with saran wrap and foil), and store it in the freezer for 2-3 weeks at the maximum.
After it’s frozen, allow it to thaw overnight in the fridge the day before you need it. Then, bake it at 400 degrees Fahrenheit for 40-45 minutes.
In the end, it’s still the same cook time, just divided.
