This is not just mushroom soup and rice. This combines fresh herbs wild mushrooms, fennel, onions, sherry and a creamy cheesy bechemel sauce, all topped with a crunchy crusty topping. This is a rich decadent side dish which is amazing with roasted turkey, chicken, cornish hens or pork. Using any rice you want, a quick cooking, or any boxed rice, or the old fashioned way. But I take the short cut for this to make my life easier, but either way, the casserole is great.
