Prepare a delicious baked brie cheese snack with a tasty topping of bacon and caramelized onion. This cheese snack recipe is served with bread and won't take much time to prepare, as you only need to brown the bacon and caramelize the onion in the pan before baking the cheese for 10 minutes. Don't forget to grease the aluminum foil slightly so it doesn't stick and serve it hot so it's melted inside.
