Japanese Sweet Potato Gratin with Aged Asiago Cheese: Adventures in Gluttony's Cheese of the Month Challenge

First things first, thank you so much to all those who commented on my Daring Bakers September Challenge post! It's always great hearing feedback and bravo to those who completed the challenge.
Besides the DB challenge this month, I was also excited about the Cheese of the Month Challenge over at Adventures in Gluttony. I love cheese and always willing to try something new, so this challenge sounded like a perfect way to explore my curiosity. If you're interested in participating for next month, head over to Adventures in Gluttony the first of every month for details. This month's chosen cheese is Asiago. I decided to use it in a gratin, but instead of with regular potato I tried it out with satsumaimo (Japanese sweet potato).

Japanese sweet potato can be found in most Asian supermarkets. Its skin is red and have a white flesh inside. This is not the same as the other Japanese sweet potato you might have heard about with the purple flesh inside that's popular in Okinawa and Hawaii. Satsumaimo are great for tempura and even more delicious simply just grilled. As for the Asiago, I went with the aged variety. I wasn't sure how well the sweetness of the potato would pair with the sharpness of the cheese, but I was in the mood for a gratin and this sounded like an interesting pairing.

I hardly make gratins and it's not because I don't like them. I actually love gratin. For goodness sake how could you not love melted baked cheese or baked breadcrumbs over anything! It's just that gratins always seem like a big family dish to me. Not only do I not have a big family to cook for, but my parents aren't the biggest fan of cheese. I'm slowly trying to ease my dad in with Swiss by adding a slice in his sandwiches every now and then, but mom...she's the tough one. Added shave slices of Parmigiano Reggiano in her salad. "It could have been better without the cheese" was her comment. Tucked a thin slice of provolone in her sandwich. Took one bite and put it down, but made her the exact sandwich a minute later minus the cheese and she ate the whole thing. I've even tried grating it on pasta and that was a no no. What really gets me is that she loves pizza though. This gratin would be my last attempt.


Japanese Sweet Potato Gratin with Aged Asiago Cheese
Ingredients
1 small Japanese sweet potato
1 small onion
Asiago cheese
1/3 cup of half and half
1 slice of white bread without the crust
2 tablespoon of butter
Salt and pepper
Preheat oven to 350 dgrees.
Chop the onion in half and slice. In a pan, add oil and caramelize the onion. Set aside.
Thinly slice the Japanese sweet potato. It doesn't need to be paper thin but do make sure it is evenly slice. You can take the skin off the potato if you like, but its' skin is thin and I think it looks nicer leaving it on.
Add 1 tablespoon of butter, 1/3 cup of half and half, salt and pepper in a pan. Cook until it's lightly simmering under low medium heat.
Add the slice Japanese sweet potato to the pan. Cook until it's tender but still has a bite to it or when the liquid has almost evaporated.
In a food processor. Pulse the white bread, about 2 tablespoons of grated Asiago cheese, and 1 tablespoon of melted butter together. This will be your breadcrumb topping.
When the Japanese sweet potato is done, arrange an even layer in the bottom of a buttered 7x5 baking dish. Top it with the caramelize onion follow by grated Asiago cheese. Top that with another even layer of the potatoes and repeat with the onion and cheese topping. Top that with your last layer of potatoes.
Bake in the oven for about 15 minutes. Top it with the breadcrumb mixture during the last 3 minutes and bake until golden brown
Serves 2

What's the verdict? She actually thought it was ok. I'm going take her "ok" comment as a nod that I should make this for Thanksgiving. I don't think I added enough grated Asiago cheese between the layer. I think I might try shredding the cheese next time. Also, I only used half and half because that was what I had in the fridge. I usually like the richer combo of milk and heavy cream instead in my gratins and would advice using that.
Do you have a favorite gratin dish? Any advice on converting non-cheese eaters?
