"This soup is absolutely wonderful. I only had 1 sweet onion so I added a red onion. That is the only change. My husband will ask for this often!"
"I just made this tonight. My first time making French Onion soup. It was easy and really really delicious. I used a box of Trader Joe's beef broth instead of canned. I added a bay leaf, and 1 tsp of beef granules. Everything else was exactly the same. (I did cook the onions on the stove to save time, and then put them in the crockpot with the broth. I will definitely make again. Hubby loved it too."
"I smashed this recipe together with another one to make a great French onion soup. Caramelized the onions in a pan first. Added 1 can of progresso French onion soup, 1 can Campbells consommé, 1 teaspoon of better than bouillon beef flavor, lawrys, parsley, garlic, salt, bay leaf. Those extra ingredients only take a minute to add and gives it a depth of flavor it needs. I triple the recipe, we love it."
"I have made this several times and it's great! My boyfriend says it's the best he has ever had. It's our favorite soup!"
