Ingredients

Directions

Make the soup

  1. Heat oil in a large pot.

  2. Saute garlic slices and chopped marjoram 2 minutes.

  3. Add the onion slices and cook about 5 minutes (or longer if you like them very soft).

  4. Add wine and broth and cook, uncovered, 10 minutes at a gentle simmer (bubbling, but not boiling).

  5. Test soup- season well with salt and pepper.

  6. Soup is ready when onions are tender- broth will be very clear & pinkish in color.

Make the toasts

  1. Meanwhile, heat up your broiler and line a baking sheet with foil.

  2. Using a 6 cm round biscuit cutter, cut bread slices into rounds (discard excess)- you may also use a glass.

  3. Set bread rounds on foil lined pan and sprinkle with cheese and broil only about 1 minute- just to melt cheese.

Serve

  1. Ladle into bowls and float a bread round on top of each bowlful, garnishing with some extra fresh marjoram if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions
Soften and sweeten as they cook slowly, forming the body of the soup.
Red onions
Add sweetness and deeper colour to the soup as they soften.
Garlic
Adds aroma that deepens as it gently sautés in the oil.
Dry white wine
Adds acidity and aromatic depth to the broth as it simmers.
Chicken broth
Provides the liquid base that carries the flavour of the soup.
Parmesan cheese
Melts over the bread rounds, adding savoury richness and browning.

The step that matters

Simmer gently, do not boil. A gentle simmer lets the broth clarify and keeps the onions tender. A hard boil makes the liquid cloudy and can toughen the onions and evaporate flavour too quickly.

Swap the marjoram

The recipe marks marjoram as optional. How well each one fits the dish's main ingredients (onion, clove, garlic, olive, white wine, chicken, bread):

  1. Thymefits better
  2. Cuminfits about as well
  3. Rosemaryfits about as well
  4. Marjoramthe original

Fit is the average pairing score against onion, clove, garlic, olive, white wine, chicken, bread. Candidates are from the same food group and used in at least 100 recipes.
