Melt butter in a pan. Add sliced onions and the cleaned and sliced mushrooms. Cook over medium-low heat, stirring a little for 10 - 15 minutes until the mushrooms release their water, begin to brown and the onion becomes soft.
Add dried thyme and paprika. Stir, cook for a minute and then deglaze the pan by adding the wine first and after a minute the vegetable broth and soy sauce. Cook over low heat until the liquid halves the volume.
Mix the milk well with the flour. Pour into the boiling soup and mix well. Cook the soup for another 3 - 5 minutes until it thickens. Taste and season with salt if necessary.
Turn off the flame. Add the lemon juice and cream and mix. Serve immediately sprinkled with chopped parsley or a drizzle of raw olive oil.
