Ingredients
- 500g yellow onions
- 1.5 L beef stock
- 2 tbsp butter
- 1 tbsp all-purpose flour
- 1/2 cup white wine
- 4 baguette slices
- 100g Gruyère cheese
- 2 sprigs fresh thyme
Instructions
- Step 1: Slice 500g yellow onions into 1/4-inch half-moons. Melt 2 tbsp butter in a heavy pot over medium-low heat, add onions, and cook slowly for 45 minutes until deeply golden and caramelized, stirring occasionally to prevent burning.
- Step 2: Stir in 1 tbsp all-purpose flour and cook for 1 minute to eliminate raw flour taste. Deglaze with 1/2 cup white wine, scraping up browned bits, and simmer until wine evaporates (about 3 minutes).
- Step 3: Add 1.5 L beef stock and 2 thyme sprigs. Simmer uncovered for 1 hour until flavors deepen and soup reduces slightly. Remove thyme. Toast baguette slices in a 350°F (175°C) oven for 5 minutes until crisp. Top each serving with 100g shredded Gruyère and broil for 2 minutes until melted and bubbly.
