Ingredients

4 Tbsp. butter
6 yellow onions (large), peeled and thinly sliced
1 tsp. sugar
1/2 tsp. salt
1 tsp. dried thyme leaves
3 Tbsp. flour
8 c. rich beef broth (simmering)

Preparation

Heat butter over medium heat in a soup pot until butter foams. Add the sliced onions; toss to coat completely.
Reduce heat to low and cover.
Cook 15 to 20 minutes until translucent.
Uncover pot; raise heat to medium.
Sprinkle onions with sugar, salt and thyme and saute very slowly until onions are a rich golden brown, about 45 minutes.
Sprinkle browned onions with the flour; cook 2 to 3 minutes, stirring.
Ladle in the simmering beef broth, whisking to incorporate liquid.
Add the sherry and simmer soup 30 minutes.
Add the lemon juice and cook 10 minutes longer.
Season with black pepper to taste.
