Potato-Mushroom Pie

Recipe photo courtesy of Gentl and Hyers

This gratin combines two comforting ingredients to their mutual advantage -- and ours. Sliced potatoes encircle a casserole dish, with assorted wild mushrooms, such as chanterelle and oyster, taking spots alongside more potatoes. Fresh thyme gives the pie herbal undertones; Gruyere and Parmesan, melting in and around the layers during baking, make it soul-satisfying.

Cook's Notes

    it tasted good but the sauce separated and looked curdled I wouln't want to serve it a party like this, anyone know where I went wrong? maybe the mushrooms weren't dry enough?

    Question: I am hoping to take this to a Christmas party. Can I cook it at home for the hour, and then the rest of the 30min to golden the cheese after I arrive at my holiday location (about 2hrs later)?

    Jidiji - I've made this two or three times, and yes, it does take the full time stated to cook. I was also sceptical about the cooking time before I'd tried it, seeing as the mandoline slices the potato so thinly, however, it really wasn't done until it had the full time. It's absolutely decicious!

    Do you have to use Yukon Gold potatoes? Would Russet work just as well?

    Does this recipe REALLY take 1 1/2 hrs. total to bake???? If you're slicing the potatoes on a mandoline, what is it exactly that takes 1 1/2 to cook?

    alibee, a mandoline is a slicer that is usually used on an angle. It is very sharp and helps to assist in getting more uniform slices versus you slicing by hand. You can find them at BB

    This is so delicious ! If the grocery doesn't have exact mushrooms I make it with Portabellos and it's very good. It looks special and your family and friends will love the extra mile you went.

    You're right, the Gruyere cheese was accidentally omitted from the ingredients list. The error has been fixed. Thank you!

    Potato-Mushroom Pie: I have the original recipe from Martha Stewart Living magazine and it calls for "1 cup finely grated Gruyere cheese (about 4 ounces)". Everything else is the same. I think they just left this out by mistake.
