Preheat oven to 350 degrees F (175 degrees C).
Layer half the halibut slices in a 9x13-inch baking dish. Mix sour cream and mayonnaise in a small bowl until smooth; spread half the sour cream mixture over halibut. Spread mushroom slices on top, followed by a layer of half the onion slices and half the Cheddar cheese. Repeat layers of halibut, sour cream mixture, onion, and Cheddar cheese.
