There's no place for delicate flavours and light textures in winter soups - they should be hearty and richly flavoured. These soups can be served as a light main course, but for a more rib-sticking meal, serve them as a starter and follow up with a seasonal main course.
French onion soup (pictured)
There are many versions of this classic French soup, but they all start with a large quantity of onion cooked slowly so it becomes sweet, soft and brown. Restaurant chefs then add rich homemade beef broth. Home cooks can 'cheat' and use canned broth, but choose the brand carefully; it should taste good on its own (the Pacific brand is recommended). The part that takes this soup from good to great is the addition of cheese-covered toast, grilled so the cheese forms long, chewy strings.
