"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!"
"Made this recipe and once I tasted it I wished I didn't have to share..."
"This was lacking something. Maybe it's the brand of beef broth that I used. I think next time I might even use a can of condensed French onion soup instead of just beef broth. I really loved how the slow cooker began to caramelize the onions. I let them cook almost two hours longer to give them a nice golden color. Like BobbiBacha, I, too, was coming down with something, and ate this and woke up this morning feeling great!"
