After many attempts via trail-and-error, this is my all time favourite onion soup recipe.
This was great. I used it as a template. To make it healthier, I upped the amount of onions, added dry red wine and served without cheese and bread. A few days later I wanted to make the leftovers more of "meal", so I added some French lentils that I cooked in beef broth, red wine and thyme. Awesome, awesome, awesome stuff!! - 11 Sep 2009 (Review from Allrecipes US | Canada)
Amazing! my brother and i actually hate onion soups but we absolutely devoured this one! i excluded the sherry and used parmesan cheese and it was just perfect! - 03 Feb 2007 (Review from Allrecipes US | Canada)
Soup was good, but I don't recommend using low sodium broth unless your diet calls for it. I made it again after using regular beef broth, and it was perfect! - 18 Jul 2004 (Review from Allrecipes US | Canada)
