French onion soup is one of my favorite comfort foods. This recipe is so easy because you make it in your slow cooker! It is easily made vegetarian by swapping the broth type, which in my opinion doesn’t impact the flavor at all.

If you don’t already buy parmesan cheese you can leave it out. It is delicious but not 100% necessary. Is this the most authentic French onion soup recipe? Not even close, but it is yummy!

Since we are focusing on budget meals around here, this one comes out to about $1.53 per serving, that’s pretty good!
