French Onion Fondue

A fondue of melty swiss, Gruyére, and caramelized onions.  

A french onion fondue

Is there a better winter meal than a bucket of melted cheese? It’s the perfect form of delicious indulgence to send off the old year and celebrate the new one with. This recipe builds of the traditional fondue base, using a mix of swiss and Gruyére, along with white wine and hints of nutmeg.  

And then it uses all the stuff that makes a bowl of French Onion magic, savory seasoned beef broth and heaps of caramelized sweet onions.  

Feel free to dunk whatever floats your boat into this bowl of cheese. I used some sourdough bread cubes and steamed Brussel sprouts (so I can pretend it was somewhat healthy), but you could also use cauliflower, broccoli, potatoes, and even grapes. Go crazy and stay warm this winter!
