french onion soup au gratin – hard core classic

by Michelle

French Onion Soup never gets old. No matter where I am in the world, if I see it on a  menu and after an encyclopedia of questions for my poor unsuspecting server, I order it. I need to know it’s the real thing.

Sunday evening we hosted our first Christmas dinner party for what feels like forever. Time being limited, I chose a classic menu. No pimping anything up. Just hard core simplicity. It was delicious! French onion soup to start, chicken paillards in green peppercorn sauce, hasselback potatoes, asparagus and chocolate mousse for dessert.

In an effort to stick to my promise of posting more than once a year, I’ve decided to show you the warts in my kitchen and when I’m cooking. In the past, I’ve happily spent hours staging every shot. I wanted to share beautiful photography with you not show you my dirty dishes. Now, I realize messy kitchens are just as interesting as staged, probably more so. So here you have it, French onion soup while I eat my breakfast on Sunday morning.

French onion soup is a mixture of sliced onions and beef stock, toasted baguette topped with grated Comté or gruyere cheese. It’s gastronomic roots are in the kitchens of Ancient Rome, prepared for the first time over 8,000 years ago. It popped up in restaurants across Paris in the 18th century and the rest is history.

My French Onion Soup strays away from beef broth and the type of cheese for the topping. I prefer a rich poultry broth and a combination of Gruyere, emmental and mozzarella cheeses to create the gorgeous gooey crust.

My spin let’s the depth of the caramelized onions shine brighter, however I would never turn my nose up at a beef broth version.

I use an old fashion hand grater with large holes to grate the cheeses. This gives me big shards of cheese that can stand up under the heat of the broiler. Hot, gooey clumps of cheese trumps a desiccated cheese topping.

Give yourself a few days to make French Onion Soup. The broth needs time on the stove and in the fridge. Removing the fat from the stock after it’s chilled is critical. No one wants an oil slick in their mouth from greasy broth. Once your homemade broth is ready, the onions will need a couple of hours over a low heat caramelizing.

As an appetizer or main course French Onion Soup is a crowd pleaser. Once made, you can stick it in the freezer until you need it for up to six months. Honestly, mine never lasts the night.
