Heat the oven to 350° F /175 °C/Gas Mark 5.
In a large frying pan, melt 2 tablespoons of butter over medium heat. Add flour and stir it until smooth and without lumps and let cook for one minute. Add onion, sugar, salt and sour cream and stir well. Add the green beans, and stir to coat with the mixture.
Place the mixture to a casserole dish. Sprinkle with the grated cheese. In a separate cup, mix remaining butter and cracker crumbs, and spread over the cheese.
