Instructions

1

Caramelize the Onions

In a large heavy-bottomed pot, melt butter with olive oil over medium-high heat. Add the thinly sliced onions, sugar, and salt. Cook for 15-18 minutes, stirring frequently, until onions are deep golden brown and caramelized. The sugar helps speed up the caramelization process. If onions start to stick, add a splash of water and scrape up the browned bits.

Pro Tip:

Use medium-high heat and stir frequently to caramelize quickly without burning. The sugar accelerates the natural caramelization process.

2

Add Wine and Broth

Add white wine to the caramelized onions and cook for 2 minutes, scraping up any browned bits from the bottom of the pot. Pour in the beef broth and add bay leaves, thyme, and black pepper. Bring to a boil, then reduce heat and simmer for 8-10 minutes to blend flavors. Remove bay leaves and taste for seasoning, adjusting salt and pepper as needed.

Pro Tip:

The wine deglazes the pot and adds depth of flavor. Don't skip this step even in the quick version.

3

Assemble and Broil

Preheat broiler to high. Ladle the hot soup into oven-safe bowls and place on a baking sheet. Top each bowl with a slice of French bread, then generously sprinkle with Gruyère and Parmesan cheese. Broil for 2-3 minutes until cheese is melted, bubbly, and golden brown on top. Remove carefully and garnish with fresh chives. Serve immediately while the cheese is still bubbling.

Pro Tip:

Watch carefully under the broiler as cheese can go from golden to burnt quickly. Use oven-safe bowls that can handle high heat.
