Melt butter in a skillet over medium heat. Cook and stir sweet onion in hot butter until browned, 5 to 7 minutes; transfer to a bowl. Add mayonnaise to the onion and stir; pour into a 9×13-inch baking dish. Sprinkle Swiss cheese over the mixture.

Bake in preheated oven until the top is bubbling and lightly golden, about 35 minutes.
