Place a Dutch oven or a heavy-based pan on low heat and add the butter. When the butter melts, add the sliced onions to the pan.

Gently cook the onions until nice and soft, stirring occasionally to avoid them burning. That usually takes around 15 minutes.

Keep stirring the onions to avoid burning them and be patient at that stage. When the onions are golden brown, add the garlic and cook for another minute.

Use vermouth or sherry to deglaze the pan then add the flour. Give it a good stir before adding the beef stock.

Add the whole bacon, bay leaves, thyme, and black pepper along with some more of the beef stock, just enough to cover the onions.

Bring it to a boil, turn the heat to low, and let it gently simmer for 45 minutes. Proceed to the preparation of the bread for serving.

Thinly slice the baguette, rub them with garlic, and place them in the oven for a few minutes until lightly toasted.

When the soup is cooked, remove the whole bacon, bay leaves, and thyme stalks. Ladle the soup in individual oven-proof bowls or ramekins.

Put a slice (or two!) of baguettes on top of the soup, top them with your cheese mixture, and place the ramekins in the oven.

Let them under the grill until the cheese is bubbly and golden. Click on 👇 "learn more" for the full recipe with step-by-step instructions.
