French Оnion Soup feels like getting a warm hug on a cold night . It started in old French kitchens way back , maybe even in Roman days , with simple onions , butter and broth . Over time cooks figured out that slow-cooking the onions until they’re sweet and brown makes all the diference . Then adding toasted bread and gooey cheese on top turned it into the cozy treat we all love today . Whether you sip it in a busy Paris bistro or eat it at home on a rainy day , this soup brings back sweet memories of family dinners and hearty meals .
What makes this soup so special is how easy it is to make yet how deep it tastes . First you caramelize onions low and slow so they get brown and sweet . Next you pour in broth and a splash of dry white wine or sherry , which gives it a little zing . Finally you float a slice of crusty bread on top and cover it with melty cheese . Broil it until the cheese bubbles and turns golden . Stick to a good recipe , but don’t be afraid to add your own twist — that’s part of the fun .
