Cooking Instructions
Here’s where the magic happens. Follow each step slowly; the caramelization of the onions is where the soul of this soup resides:
-
Caramelize The Onions
- Melt butter with olive oil in a large heavy-bottomed pot over medium heat.
- Add sliced onions, a pinch of salt, and cook slowly for 30-40 minutes, stirring occasionally.
- Patience is key here; onions should be golden brown, sweet, and fragrant.
-
Add Garlic And Flour
- Stir in the minced garlic and cook for 1-2 minutes.
- Sprinkle the flour over the onions, stir constantly for 2-3 minutes to remove the raw taste.
-
Deglaze And Simmer
- Pour in the white wine or sherry to deglaze the pot, scraping up any brown bits.
- Add the beef broth, thyme, and bay leaf. Bring to a gentle simmer and let it cook for 20-25 minutes.
-
Final Seasoning
- Remove thyme sprigs and bay leaf. Taste and adjust salt and pepper as needed.
-
Prepare The Cheese Toasts
- Preheat the broiler.
- Place toasted baguette slices on a baking sheet, sprinkle generously with shredded Gruyère, and broil until melted and bubbly.
-
Serve
- Ladle soup into oven-safe bowls, float one or two cheesy toasts on top, and, if desired, broil for a minute for that signature golden crust.
