Preheat oven to broil. Add bacon to large skillet over medium heat. Cook, stirring occasionally, until golden-brown and crisp, about 5 to 8 minutes. Transfer bacon to a paper-towel-lined plate. Set aside. Add Brussels sprouts to skillet, cut-side-down, and cook until light golden-brown, about 6 to 8 minutes. Season with salt and pepper, to taste. Stir in butter and garlic, and cook until garlic is fragrant, about 30 seconds. Stir in heavy cream. Remove from heat.
Top with Gruyere, Swiss cheese and reserved bacon. Broil until cheese is melted and light golden-brown, about 2 to 3 minutes. Serve and enjoy.
