Step-by-step instructions
- Melt and Sauté: In a large pot, melt the butter along with the olive oil over medium heat. This combination prevents the butter from burning.
- Caramelize Onions: Add the sliced onions, salt, and sugar into the pot. Stir frequently, allowing the onions to cook down and caramelize beautifully for about 30-40 minutes. Take your time for maximum flavor.
- Add Broth and Wine: Sprinkle the thyme over the onions, then pour in the beef broth and white wine if using. Bring everything to a gentle boil, then reduce the heat and let it simmer for about 30 minutes to meld the flavors.
- Get Broiler Ready: Preheat your broiler. Ladle the hot soup into oven-safe bowls, top each with a slice of baguette, and generously cover with grated Gruyère cheese.
- Broil to Perfection: Broil the bowls until the cheese is bubbly and golden brown. Keep a close watch, as it can go from perfect to burnt quickly!
- Serve Hot: Carefully remove the bowls from the oven and serve immediately. Enjoy the wonderful aroma and warmth!
Best ways to enjoy it
French onion soup is best enjoyed piping hot. Serve it alongside a crisp green salad to balance out the richness, or consider pairing it with a glass of Pinot Noir for a delightful contrast. For a more casual touch, some crunchy garlic bread on the side would enhance the experience nicely.
Storage and reheating tips
If you have leftovers, store the soup in an airtight container in the refrigerator for up to 4 days. To ensure the crispy baguette doesn’t become soggy, store it separately. When reheating, gently warm the soup on the stovetop. You can re-broil the cheese on top if desired — just use an oven-safe dish.
Helpful cooking tips
- Patience is key when caramelizing onions; let them do their thing without rushing!
- Use a heavy-bottomed pot to distribute heat evenly—this helps avoid burning.
- Don’t skimp on cheese! A generous layer is essential for that famous melt and bubbly crust.
Creative twists
Feel free to experiment with flavors: add a splash of balsamic vinegar for a tangy depth, or swap out the beef broth for vegetable broth to make a vegetarian version. You can even toss in some sautéed mushrooms or add a sprinkle of cayenne pepper for a bit of heat.
