How to Make French Onion Soup
- Begin by slicing an onion in half lengthwise, and cutting it into ¼” thick slices.
- With a large pot over high heat, add butter and allow to melt.
- Add sliced onion, minced garlic, thyme, and bay leaves and sauté until onions are translucent and soften, about 5 minutes. Season with a few pinches of salt.
- Reduce heat to medium-high and continue to cook the onion until soft and caramelized, stirring frequently.
- As the onion gets closer to being caramelized, the bottom of the pan may start to burn, add a little bit of the beef broth to deglaze it as the onion continues to cook.
- When the onions are a deep golden caramel color, about 25 minutes, add the rest of the beef broth to the pot.
- Bring to a boil and simmer for another 10 minutes, season with salt and pepper to taste.
- Shred or grate cheese, and slice bread into ¼” – ½” round slices that will fit inside an oven-safe bowl.
- Remove thyme and bay leaves from the soup, and divide into oven-safe serving bowls.
- When ready to eat, place a slice of bread on top of your soup and top generously with grated Fontina cheese.
- Broil for 4 minutes until cheese is melted and golden.
- Remove from oven and serve immediately. Enjoy!
French Onion Soup Classic Recipe Tips
- Deglaze the pan with white wine or red wine before adding the rest of the beef broth and letting the soup simmer for additional flavor.
- You can make this a vegetarian French onion soup by using vegetable stock or broth instead of beef. You could even substitute the cheese for a vegan option, if preferred.
- If you don’t have oven-safe bowls, you can toast the bread slices separately and add a slice to each bowl of soup before serving.
- You can make this French onion soup recipe in the slow cooker by adding the ingredients to a crockpot and cooking on low for 8 hours or on high for 4-5 hours, after caramelizing the onions.
- Use a sweet onion for this recipe – only use white onions if they’re all you have on hand.
