French Onion Soup Grilled Cheese Sandwiches

Did you read that title and immediately think “uh...?” while salivating a bit? Because that was basically my reaction when I found out about these sandwiches. We are very pro-grilled cheese in this house so any and all twists are welcomed! There are quite a number of recipes out there for this particular sandwich but it's so simple, you really don't need one.

Take just about everything you'd use to make french onion soup but rearrange things a bit. Caramelize two medium onions in butter and oil, sugar, thyme, and white wine or broth, grate some delicious Swiss gruyère, spread lots o' butter on thick slices of a baguette or, in my case, sourdough and boom, you're in business!

I went to town on these onions but that's because we love super-caramelized onions. Keep an eye on them if you're not too keen on them becoming too brown, you don't want to end up with burned onions!

After letting your bread soak up a good amount of butter, top with the onions and grated cheese. Grating the cheese will help with the melting process, so don't skip that step! It will result in an amazingly gooey sandwich.

I combined and modified these two recipes from Tasty Kitchen and Portuguese Girl Cooks to come up with the above. I strongly suggest you make these. STRONGLY!
