This is, by far, the most delicious French onion soup I have ever tasted. I merged two recipes in the style of Martha Stewart and Paula Deen to come up with the absolute best French Onion Soup in the world. I kid you not, this is the best you will ever have, if you adhere to a few key steps.
Two details of importance, when making GREAT French onion soup: (1) Slow cooking the onions for about an hour and a half on very low heat. This will really mellow the onions and bring out amazing flavors. (2) Use imported Gruyere Cheese. Imported Gruyere is a bit pricey compared to some other cheeses (I recently paid about $19.00 per pound). You need about a half pound of cheese, which would cost around $10.00. I know, some of you will cringe at that, but really this soup is amazing and well worth it. Make it as a special treat. But promise me, that at least once, you will use the imported Gruyere (from France), just to treat yourself. And I will promise that you will LOVE it.
Just this weekend, I made this soup for my parents who both agreed: It was the BEST French Onion Soup they ever had!!!
