Hi friends! Today I’m excited to not only bring you the most delicious Crock Pot French Onion Soup recipe, but just like we did last year, we’re continuing on with 12 Bloggers – 12 Months – 12 Ingredients (or less)! Remember, each month again this year on the 12th, 11 of my bloggy friends and I are bringing you a delicious and easy recipe, with a theme! And the theme this month is 12 Slow Cooker Soup Recipes!

Mmmm…I just love soup recipes for this time of year. The perfect meal to heat up your home and your belly! One of my favorite soups to order when we’re out is French Onion Soup. I had always thought it would be near impossible to make at home – but with this crock pot recipe and just a little time to get those onions golden, you’ll be amazed at how well it turns out!

I started out the soup by browning two JUMBO onions in butter, adding a little sugar at the end and letting them carmalize a bit. I then added a little cooking sherry to deglaze the pan and get all those yummy browned butter bits. I transfterred this aromatic onion mixture to the crock pot, added some beef broth and spices and cooked for a few hours and voila! Delicious soup.

But that’s not all. Once I knew I was about to serve up the soup, I simply tossed some mozzarrella and parmesan cheese (you can also substitute with gruyere and emmental) on top of a slice of french bread and broiled that until the cheese was bubbly and browning. Top off your cup (or bowl) of soup with this cheesy bread and you’re set to go!
