Why You’ll Love This Recipe
If you love caramelized onions, but don’t want to stand around stirring onions forever, you’re going to love this Simple Slow Cooker French Onion Soup.
Yes, it takes awhile to caramelize onions in the slow cooker too, but when you do, you can walk away and come back hours later to perfectly golden, soft and flavorful onions.
And of course, French onion soup is the perfect way to showcase caramelized onions. In fact, as the name suggests, onions are the star of this recipe.
Trust me, once you’ve made French onion soup this way, you’ll never go back to the stove-top method!
Even people who say they don’t like onions (like my husband), love this soup. In fact, he says it’s one of his favorites and requests it often. I love onions, so I’m always happy to oblige.
As much as I love onions, I have to admit that my favorite thing about this soup are the crusty baguette slices with melted cheese.
The recipe calls for Gruyere, but if that’s not available, shredded mozzarella will do the trick. Fontina is another good choice that melts easily and tastes amazing.
There are so many things I love about this soup, including the fact that it’s kind of fancy and gourmet, yet so simple and economical to make.
With the exception of the cheese, you really won’t find less expensive ingredients than beef broth, onions and day old bread.
