How to Make the Best French Onion Soup:
Caramelize the Onions
Melt the butter in a large pot set to medium-low heat. Add the onions, season with salt and allow them to cook down for 30-40 minutes, until lightly browned and tender. Stir the onions every few minutes. Don't rush this step, having nicely caramelized onions will result in a more flavourful soup.
Turn Onions into Soup
Once the onions are caramelized, turn the heat to medium-high. Sprinkle the onions with the flour and cook for 1-2 minutes. Add the Peppercorn Rye Saison and bring to a boil. Scrape any bits of flour left on the bottom of the pan. Add the stock, bay leaves, and thyme. Simmer covered for at least 30 minutes.
All the Cheese
This is where the magic happens - creating the beautifully melted, cheesy crust that tops the French onion soup. For this, you need to butter both sides of your baguette slices. Toast in a preheated oven until browned. Using oven-proof bowls on a baking sheet, fill them with the soup, leaving about a quarter inch of space. Top with a couple of slices of baguette and smother with a handful of Swiss cheese. Switch your oven to broil and melt the cheese until golden and bubbly, about 3-4 minutes. They'll be hot so allow them to cool for at least 5 minutes before serving.

I've been trying to find a good recipe for an experiment using left-over wort when we make our Pretty Purple Porter at our brewery (ManyFriends Brewing Company), and this is perfect! Wort is not as tasty as beer, but it still made an excellent base for this delicious soup. Thanks for the inspiration!
