When entertaining guests, I bring out this savory soup while we're waiting for the main course. It's simple to make—just saute the onions early in the day and let the soup simmer until dinner-time. In winter, big bowls of it make a warming supper with a salad and biscuits. —Linda Adolph, Edmonton, Alberta

"To the people complaining it's not vegetarian, use Vegetable broth!"

"I also carmelized the onions. I made the rest of the recipe as stated and it will now be my "go to" recipe."

"I cut it down because it is just two of us. I didn't chop the onions but sliced them then cut then slices in half. I liked the flavor of the onions. I like the flavor the Parmesan cheese gave to it as well."

"I use the slow cooker to caramelize the onions first in the slow cooker, then do the rest of the recipe so it takes me a full day to do this soup. I put the onions on overnight, add the rest in the morning and prepare as above. Sometimes I add thyme also. I want to try the idea mentioned of using cider. I'll use apple juice instead since I always have it on hand and see how it is. Sounds really unique and tasty."

"While I haven't made this specific recipe, I just wanted to mention that you can also use the "Better Than Bouillon" beef base instead of the canned soup (3 Tbsp. base to 8 cups water). They even make a low salt version although I just use the regular version and to us the salt level is perfect. I too caramelize the onions in butter with a little oil, 4 Tbsp. butter with 2 Tbsp. oil, in a large pot. Once caramelized, I sprinkle with 3 Tbsp. flour;stir, and then add the base/water to the pan. To make the soup on the stove top, after combining all the ingredients, bring to a boil and then lower to a simmer, partially covered, for 45 minutes before ladling it into the ovenproof bowls. We prefer Mozzarella only and my husband likes it when I put some of the shredded cheese in the bottom of the bowl before ladling in the soup, then the bread with lots of cheese on top and then under the broiler. You can also sprinkle with a little paprika if you wish for a little added color."
