Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Rich French Onion Soup
Ingredients
Directions
Make the soup
Put the butter and oil in a large pan and heat.
Add the onion and garlic and cook on a high heat until the onions turn a deep golden brown.
Stir to prevent sticking. Add the sugar and reduce the heat.
Cover the pan and cook gently for 20 minutes.
Make the consommé up to 1.21 (2pts) with water and add to the pan, with the wine.
Simmer without the lid for 45 minutes.
Season with salt and pepper.
Top and serve
Toast the bread, spread with butter and sprinkle with cheese and parsley.
Put under the grill until the cheese has melted. Ladle the soup into bowls and put the toast on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red onions
- Slow browning builds the deep golden color and sweet, rich flavor of the soup.
- Beef consommé
- Forms the savory liquid base of the soup.
- Dry white wine
- Adds acidity and aroma that brighten the rich broth.
- Cheddar cheese
- Melts over the toast, adding fat, body and savory flavor.
- French loaf
- Toasted slices hold up under the cheese and soak up some soup.
The step that matters
Browning the onions on a high heat. Onions must turn deep golden brown to develop the sweet, caramelized flavor the soup depends on. Stirring prevents scorching on the pan base, while the sugar helps the onions brown evenly.
