This is a favorite of my family's. Whenever I cook this dish, my husband and son wolf it down. I strongly recommend it.
This has been my favourite gratin for years. It's my mom's recipe. I rearranged the taste a little bit.
It's better to use a deep gratin dish When you are using a shallow one, you can just make 2 layers with the meat and mashed potatoes.
Enjoy Japanese food around the world.
