The most important step in this recipe is caramelizing the onions. They need to cook for 30 minutes to develop that dark brown hue and sweet taste. Caramelized onions are good in anything soup, dip and now sandwiches.
Try not to stir your onions to much. Keep them in a thin layer and stir ever so often.
To assemble this French Onion Grilled Cheese place buttered pieces of bread (I used whole wheat) in a large skillet or griddle. Layer with Swiss cheese and caramelized onion. I used extra thin slices of Swiss that is why it calls for 6 slices on each sandwich. You can use less if you are using regular slices of Swiss cheese.
Serve this sandwich with a side of warm beef broth and enjoy.
