Waffling Leftovers: Potato Gratin

Another day, another set of leftovers to play with in my waffle iron: potato gratin!

If you have no idea what I'm talking about, go read my intro to my Waffling Leftovers series, and perhaps browse a few of those stories first ...

The big question: Potato Gratin: Will it Waffle?  Basically, but, I think this is better left to traditional reheating techniques.
Parmesan Crusted Potato Gratin.
Here was the original dish, a decadent, totally delicious gratin of sliced sweet potatoes and red potatoes, absolutely loaded with heavy cream, butter, and Parmesan cheese, with a little panko on top for crunch.

I don't think I need to tell you how amazing this was, just given those ingredients.  I obviously saved leftovers.

It turned out to be really delicious cold as well, more like a potato salad.  And it reheated fine traditionally in a toaster oven too.

But I can't leave well enough alone.  Must. Waffle. All. The. Things.

If I can waffle mashed potatoes, I can waffle potato gratin, right?
Several minutes in ...
After a few minutes, I checked on it.

Uh-oh, things weren't looking good.  Half the grill plate was filled with oil.  Most of the gratin was stuck to the lid.  I immediately started thinking that I should have crusted it.  But I left it going ...
This side looks good!
When I checked a few minutes later, it looked ok, although not quite as crispy as I wanted.  I thought that the cheese would get all crispy like with pizza when it runs out into the waffle iron, and that the potatoes would get crazy crispy like a potato pancake.

So I left it a big longer.  The top side never advanced past what you see above, still never quite that crisp.
The other side? Not so much.
But, the other side?  When I pulled it out, I was devastated.  The bottom was totally burnt.  The last few times I used the waffle iron I was concerned that one side was hotter than the other, but this pretty much confirmed it.   Doh!
Note to self: don't just watch the top side, watch the bottom too!

Anyway, besides being burnt, it was still only a quasi-success.

The oil that ran out all over the iron was from the cheese, and the result was that all of the cheesy deliciousness was lost.  The potato did get crispy, and that was good, but, it was really just crispy potato waffles at this point, perfectly good, but a waste of gratin!

Perhaps I could try crusting it to help some of the cheese stay in.  I could certainly flip it halfway and avoid the burnt half.  But ... gratin reheats perfectly fine in a toaster oven, so I think this one may go the way of the shepherd's pie, and be better left to traditional methods ...
