Preheat the oven to 350 degrees F (175 degrees C).
Mix green beans, condensed soup, 1/2 cup milk, sour cream, Swiss cheese, 1/2 of the French-fried onions, garlic salt, soy sauce, and pepper together in a large casserole dish.
Bake, covered, for 30 minutes adding a little more milk halfway through the cooking time if a creamier consistency is desired.
Remove from the oven and add remaining onions to the top. Bake, uncovered, until bubbly, about 15 more minutes.
