Questions about French onion soup
How do you get the onions properly caramelised for French onion soup?
Slice them evenly and cook slowly in butter or oil over a low to medium heat, stirring often, for about 35–45 minutes. They should turn deep golden brown and soft, not black; lower the heat if they catch.
How do you make the cheesy bread topping?
Ladle hot soup into ovenproof bowls, top each with a slice of toasted baguette and grated Gruyère, then grill for 2–4 minutes until the cheese is bubbling and browned. Set the bowls on a sturdy baking tray and use oven gloves: they will be very hot.
Can you make French onion soup ahead of time, and how should you store it?
Yes. Cool the soup promptly, refrigerate it in a covered container for up to 3 days, and reheat until steaming; add the bread and cheese only when serving so they do not turn soggy.
What can you serve with French onion soup?
It is often served as a filling starter or light meal with toasted baguette and melted Gruyère. A crisp green salad makes a fresh contrast to the rich, savoury soup.
What can you use instead of Gruyère on French onion soup?
Comté or Emmental melts well and gives a similar savoury topping. For a stronger flavour, use mature Cheddar, though it will taste less traditional.
Why is French onion soup usually topped with bread and melted cheese?
The bread soaks up the savoury onion broth, while the cheese melts over it to form the browned, bubbling crust known as a gratinée topping. That contrast of soft bread and crisp, golden cheese is a hallmark of the dish.
How is French onion soup different from clear onion soup?
French onion soup is usually made with slowly browned onions and stock, then served with bread and melted cheese. Clear onion soup is a lighter broth; per 100 g it has 27 kcal, compared with 82 kcal in French onion soup.
