This is another recipe I was given by Aunt Della (no prunes in this one!she says she found this recipe in the newspaper a long time ago.The original recipe calls for 1/3 c wine but she substitutes milk .
She also said you cause dry thyme and sage,she uses fresh because she grows them,us half the amount if you do.
This was a delicious side dish that went well with pork chops but I'm sure would go with any dish. Very tasty!

How to Make Della's Mushroom & Potato Casserole


  1. Preheat oven to 375º. Lightly grease a 9x13-inch baking dish with butter or non-stick spray.
    Heat butter and olive oil in a large pan or skillet and sauté mushrooms and onions until soft,about 3-5 minutes.
    Add minced garlic, thyme and sage, season with salt and pepper, and cook for another 1 minute, or until fragrant.
    Pour in milk and cook for another 3 minutes, or until liquid has mostly evaporated.
    Remove from heat and set aside.
    Arrange 1 layer of potato slices on the bottom, then add a layer of sautéed mushrooms.
    Repeat with remaining vegetable layers.
    In a small bowl, whisk the chicken stock into the cream of mushroom soup, then pour mixture over the mushrooms and potatoes, tapping the baking dish against the counter to make sure the liquid gets in between the vegetables.
    Sprinkle the cheeses over the top, cover with aluminum foil and place baking dish in oven.
    Bake for 40 minutes, then uncover and bake for another 20 minutes.
    Remove from oven and let cool 5 minutes before serving.
