Gotcha! Not the end. I have more to say. Mostly about the juicy chicken. and the super melty swiss cheese. and the tender savory caramelized onions on fluffy slider buns. We had these for dinner a couple of weeks back (though really, they would make an incredible appetizer too) and I couldn’t get enough. If I’d had enough physical stomach space I would have eaten all 8 of them myself.

My favorite part ended up being the dijon mustard, which usually I would go light on due to personal taste, but I ended up dipping these sliders into hoards and hoards of extra dijon mustard. I’m putting these back on the menu right away because I can’t get over how amazing the flavor of these soup-inspired sandwiches is! Plus they’re easy peasy and come together in 30 minutes or less!

Winner winner French onion chicken slider dinner.
