French onion soup. Really cook them onions down. At least 45 mins. Wine & brandy. Gruyere baguette toasty bits on top are a must.
Harira. A spicy chickpea & chicken soup. Often eaten to break a Ramadan fast. Utterly delicious. A real warmer with mellow North African spices. Can omit the chicken if you are a veggie.
Crab chowder.
Carrot and coriander.
Broccoli and Stilton. Also works as a Christmas leftover in the guise of sprout and Stilton. Oh that works. Stand clear though eh?
Classic Italian Ribolitta.
As others have said, butternut squash and curried parsnip are true Autumn / winter classics.
Stews? Take your pick. Onions, carrots, celery of course. Your choice of beer or wine with stock. Beef? Rabbit? Chicken? Pearl barley? Mushrooms towards the end? Knob of butter or dollop of yog to finish? Slow cooked oxtail is a fave. Always seems a bit odd opening a can of ale before going to work. Ho hum.
Ooh don’t forget them thar dumplings.
It’s Autumn. You are limited by your imagination and your ability to Google recipes.
