Clear stars, so easy and so delicious.
I used my own homemeade stock, and this was just fantastic.
I did not have gruyere, but used cheddar and mozarella together.
So very good, with fantastic falvours.
This is a must recipe for onion soup lovers.
Thanks Boomette.

Yummy onion soup! I loved the addition of a tomatoes for a change and the gruyere cheese is to die for. So rich and flavorful. Thanks for sharing!

Delicious!! This is so good with the deep rich flavors of the beef and port wine topped off by that yummy gruyere cheese. This is defiantly restaurant quality recipe. Made using a smoked gruyere and had to put in the oven to melt the cheese as my broil chose tonight to go on the blink. Thanks so much for the post.
