This five-ingredient recipe is one of the easiest fish casseroles you'll ever find. The cheesy shrimp sauce is made with canned soup and takes just minutes to prepare.
1. Heat oven to 400 degrees F. Coat bottom of 8 x 11-inch baking dish or 4 ramekins (2 cup capacity) with just enough soup to cover.
2. Place fish on top and pour remaining soup over fish. Sprinkle crushed crackers over fish; top evenly with cheese. Pour milk on top.
3. Cover with foil and bake at 400 degrees F for 1 hour or 35 minutes for ramekins. Let cool slightly before serving.
