French Onion Soup

Onions caramelized slowly and simmered in beef broth. I finish the bowls under the broiler with toasted bread and melted gruyère.

Why This Works

Low, slow caramelization breaks down the onions' complex sugars over 45+ minutes into deep, sweet, savory compounds that no shortcut can replicate — it's pure chemistry you cannot rush.

The Upgrade

Add a splash of cognac or dry sherry to the onions right before the stock — it adds an extraordinary depth that's unmistakably French.

Chef's Secret

Michelin Technique

The secret is patience: the onions need a full 45–60 minutes on low heat, stirred every 5–10 minutes. Any browning on the bottom of the pot is gold — deglaze it with a splash of wine and scrape it all back in.

Wine Pairing

🍷

Beaujolais

Red Wine

The BottleJean-Paul & Charly Thévenet Morgon Vieilles Vignes

The vibrant red fruit profile and bright acidity of a Gamay from Morgon cut cleanly through the rich, molten gruyère and deeply caramelized onion sweetness. Its low tannins ensure the wine doesn't clash with the savory beef broth, while a subtle earthy undertone mirrors the fresh thyme for a seamless, harmonious pairing.
