French Onion Cheese Fondue - An ooey gooey three-cheese fondue studded with deeply caramelized onions. |

You guys, it’s the last Epic Game Day recipe. I’m sort of sad it’s all over. I’ve had so much fun sharing all of my “home chef” party food recipes with you guys. But, the game is this weekend, and all good things must come to an end.

Don’t worry . . . we’re going out with a bang. What’s a party without a supremely gooey cheese dip? And this French Onion Cheese Fondue, oh man. It’s a blend of three of the tastiest and best melting cheeses in the world.

Why have one cheese when you can have three? And then, it’s kicked up a notch with a big batch of deeply caramelized onions.

This French Onion Cheese Fondue comes together really quickly on game day if you caramelize the onions in advance and just keep them in the fridge (make extra if you also want to make some pretzel bun sliders).

Then, on game day, you’ll be stirring the cheeses into a bit of white wine until they’re nice and melted, and then adding those amazing caramelized onions.

I’m not sure about you, but when I think of good cheese, I think of Wisconsin. So, all of the cheeses used in this fondue are straight from the Badger state. Here’s the run-down on the cheese situation I have going on here. Equal parts:

  • Fontina – Considered one of the most versatile cheeses in the world because it is excellent as both a table cheese and a cooking cheese. Fontina is often used as the cheesy layer served atop French onion soup.
  • Butterkase –  Its name literally means “butter cheese.” Although it contains no butter, it has a butter-like texture and is very mild and creamy.
  • Shredded Grand Cru Original – A rich, nutty Alpine-style cheese. Robust and full-bodied, this award-winning cheese melts beautifully.
