4 tablespoons unsalted butter
1 cup onions, minced
1 cup shiitake mushrooms, sliced
4 cups green beans, blanched and frenched
3 cups chicken broth
2 cans condensed cream-of-mushroom soup (10 and 3⁄4 ounces each)
2 cans French-fried onion rings (2.8 ounces each)
2 cups Vermont Cabot cheddar, grated
Preheat oven to 350 degrees. Melt butter in a large pan. Sauté onions in butter until translucent. Remove onions and add mushrooms; sauté mushrooms until lightly browned.
Combine chicken stock, mushroom soup, blanched beans, and sautéed onions and mushrooms in a large mixing bowl. Mix with a kitchen spoon until ingredients are combined; season with fresh ground black pepper and salt. Place the mixture in a buttered casserole and top with grated cheddar.
Place in oven and bake until cheese is browned and casserole is bubbling. Top with French-fried onions
