Author's Notes

Russet potatoes work well for this recipe. However, I've also used red potatoes with equally good results.

The covered cooking time will vary slightly depending on how thin you've sliced the potatoes. I find cutting them by hand instead of using a mandolin requires closer to 60 minutes covered.

I like using cremini mushrooms for this recipe as they have a little more earthiness than regular white mushrooms. However, either works well as does a mix of mushrooms.
