Introduce the recipe and ingredients for French onion soup.

Use 75% Spanish onions and 25% red onions, slicing them all at once.

Add 2 tablespoons each of garlic and shallots, adjusting for personal taste.

Use olive oil as the fat for cooking, avoiding animal fats.

Lightly coat a rondo or large soup pot with olive oil and heat to medium-low.

Add the sliced onions to the pot and sprinkle with salt to help break them down.

Cook the onions for 30 to 45 minutes, stirring occasionally to avoid burning.

Prepare crostini by slicing stale baguette about 1 centimeter thick, toasting it, and seasoning with olive oil, salt, and pepper.

Wrap fresh herbs (rosemary, thyme, tarragon, bay leaf) in cheesecloth and tie with butcher's twine.

After the onions have softened, add the garlic, shallots, and the bouquet of herbs to the pot.

Stir and continue cooking for another 45 minutes.

Add red wine, sherry, and Madeira to the pot, cooking off the alcohol.

Add demi-glace diluted with water to the pot, using about 3 quarts of demi-glace and 2 quarts of water.

Stir to combine and simmer for another 45 minutes to develop flavor.

Taste and adjust seasoning with sherry vinegar, Worcestershire sauce, salt, and pepper as needed.

Finish the soup with crostini and a generous amount of grated gruyère cheese on top.
