Step 1
Slice the onions thinly, keeping the layers separate.
Step 2
Melt butter in a large pot over medium heat.
Step 3
Add sliced onions and sauté for 8-10 minutes, stirring occasionally, until deeply caramelized and golden brown.
Step 4
Sprinkle flour over the caramelized onions and stir constantly for 2-3 minutes to toast the flour and eliminate raw taste.
Step 5
Gradually pour in vegetable broth while stirring to avoid lumps.
Step 6
Bring to a simmer and cook for 10-12 minutes, stirring occasionally, until the soup thickens slightly.
Step 7
Season with salt and black pepper to taste.
Step 8
Ladle into bowls and garnish with fresh parsley before serving.
