Underneath all of the cheesy bread goodness, you’ve got one of the best things on earth – a Philly cheesesteak! This recipe combines a classic French onion soup with a seriously mouthwatering cheesesteak sandwich. It’s a crockpot recipe so it’s ridiculously easy and does the work itself.

When I think about winter, one thing comes to mind: soup! Although it’s not truly winter yet, I have been relishing in allll the soup recipes and plan to do so for the next couple of months!

French onion soup is one of my favorites in the soup club. Cheese, bread, caramelized onions. How can you go wrong here? I love, love, LOVE French onion soup but if I’m being honest it intimidates me a little bit. In walks my crockpot…

“This doesn’t have to be so difficult” she whispers to me. And that’s how this recipe was born. With this crockpot recipe, you are literally throwing everything in a pot and walking away. BYYYE, see you!

We are adding in all of the elements of a Philly cheesesteak because I’m constantly craving one of those and let’s be real – this is where I have more confidence. Living right outside of Philly gives us access to the best cheesesteaks, basically anytime we are down to go! I feel like when it comes to Philly cheesesteaks, it is one of those things I couldn’t fathom ever getting tired of – even if I ate one every night for dinner!

So let me introduce you to your cravings answered and a true winter soup dream! I hope you enjoy this recipe as much as our little tribe has time and time again.
