Ingredients
🧅 4 large yellow or sweet onions, thinly sliced
🧴 2 tbsp olive oil (or unsalted butter for richness)
🍷 1 cup dry white wine (like Sauvignon Blanc)
🍯 4 cups beef broth (low-sodium preferred)
🧂 1 tsp dried thyme (or 1 tbsp fresh thyme leaves)
🧀 1 cup shredded Gruyère cheese (or Swiss if needed)
🍞 4 slices of toasted baguette (or any crusty bread)
Optional additions: splash of Worcestershire, pinch of sugar for faster caramelizing, or a garlic rub on your toast!
Instructions
1. Caramelize the Onions (Fast-Track Version)
In a large pot, heat olive oil over medium heat. Add sliced onions and sauté, stirring often, for about 15 minutes, until they’re golden brown and soft. If they’re browning too fast, reduce the heat slightly. Optional: add a pinch of sugar to help speed up caramelization.
2. Add the Wine
Pour in the white wine, scraping up any browned bits from the bottom of the pot. Simmer for 2–3 minutes until the wine reduces slightly.
3. Add Broth and Thyme
Stir in the beef broth and thyme. Bring to a simmer, then reduce the heat and let it cook gently for 15–20 minutes.
4. Toast the Bread
While the soup simmers, toast the baguette slices until golden. For extra flavor, rub each slice with a clove of garlic once toasted.
5. Broil and Serve
Ladle soup into oven-safe bowls. Top each with a slice of baguette and a generous handful of Gruyère cheese. Place under a broiler for 3–5 minutes, or until the cheese is melted, bubbly, and lightly browned. Serve hot!
Tips for Success
- Use sweet or yellow onions for the best flavor
- Slice onions thinly and evenly so they cook uniformly
- For a deeper flavor, try using half chicken broth, half beef broth
- Don’t skip the broil—that’s where the cheesy magic happens
- If you don’t have oven-safe bowls, broil the toast separately and float on top
