In my opinion, the best mushroom soup recipe is the one from Hungarian cuisine with pieces of mushrooms and small homemade egg noodles.
Frying Onion and Bell Pepper
Heat the oil in a pot and sauté the chopped onion for a minute over medium heat, add the diced pepper, the salt, fry for another minute.
Add the Mushrooms
Add the sliced mushrooms, mix and season with fresh thyme that you chopped finely and Hungarian sweet paprika.
Flour on the Mushrooms
Add the flour, mix and let it absorb for a minute from the liquid; the flour will have the role of thickening the soup a little.
Boiling Mushroom Soup
Pour the water, season with sea salt, freshly ground pepper, vegetable mix for soups and simmer over medium-small heat for about 20 minutes.
In a bowl, break a fresh egg, and add the wheat flour. With a fork, mix everything well until you get a kind of paste, thin but not liquid.
Add Noodles to the Soup
With a teaspoon, add small amounts of dough in the soup, which in contact with hot water will swell a little and float to the surface.
Boiling the Noodles
Boil the dumplings for about five minutes on low heat, add the juice of half a lemon, a tablespoon of chopped parsley and ready.
Serving the Mushrooms Soup
Serve warm with a bit of hot chilly if you like, and a tablespoon of sour cream or Greek yoghurt will make it more creamy and tasty.
