Step-by-Step Beginner-Friendly Instructions
- Caramelize the Onions: Heat butter and olive oil in your pot over medium heat. Add the sliced onions and coat thoroughly. Cook, stirring occasionally, for 35–45 minutes until deep golden brown. 🧅
- Thicken and Deglaze: Stir in the flour and cook for 1 minute to remove the raw taste. Gradually pour in the beef stock while stirring constantly to prevent clumps.
- Simmer: Add the thyme and bay leaf. Bring to a boil, then reduce heat and simmer for 20 minutes to allow the flavors to meld together.
- Toast the Bread: While the soup simmers, place baguette slices on a baking sheet and toast in the oven until golden brown.
- Broil: Ladle soup into oven-safe bowls. Top with a slice of bread and a generous handful of Gruyere. Broil for 3–5 minutes until the cheese is bubbling and slightly browned. ✨
💡 Pro Tips
- Storage: Keep leftover soup in an airtight container in the fridge for up to 3 days. Freeze without the bread and cheese for up to 2 months.
- Onion Tip: Don’t rush the caramelization! If the onions start to burn, lower the heat and add a tablespoon of water to deglaze the bottom of the pot.
- Flavor Boost: If you want a deeper flavor, add a splash of balsamic vinegar during the last 5 minutes of caramelizing your onions.
Variations
- Vegetarian Twist: Substitute the beef stock with a high-quality roasted mushroom or vegetable stock.
- Cheesy Crunch: Mix in a little grated Parmesan with the Gruyere for an extra salty, savory crust.
FAQ
Can I make this ahead of time? Yes! The soup base actually tastes better the next day after the flavors have had time to settle.
Do I have to use oven-safe bowls? If you don’t have oven-safe bowls, you can melt the cheese on the bread slices on a baking sheet under the broiler and simply place the cheesy toast on top of the bowl of hot soup just before serving.
