Total Time: 8 hrs 15 mins
Cuisine: French
Serves: 6 servings
Ingredients
- 4 large onions, thinly sliced
- 4 cups beef broth
- 1 cup white wine
- 2 tbsp butter
- 1 tsp thyme
- Salt and pepper to taste
- 6 slices of baguette
- 1 cup Gruyère cheese, shredded
Instructions
- Begin by preparing your ingredients. Thinly slice the 4 large onions and set them aside. Measure out 4 cups of beef broth, 1 cup of white wine, and have 2 tablespoons of butter ready. Also, gather 1 teaspoon of thyme, salt, and pepper to taste.
- In a large skillet or frying pan, melt the 2 tablespoons of butter over medium heat. Once the butter is melted and foamy, add the sliced onions to the pan.
- Cook the onions slowly, stirring occasionally, for about 10 to 15 minutes until they become soft and translucent. This initial cooking will help to bring out the natural sweetness of the onions.
- Once the onions are soft, reduce the heat to low and continue to cook them for another 30 to 40 minutes, stirring occasionally. The onions should turn a deep golden brown color, which is crucial for the flavor of the soup.
- After the onions have caramelized, transfer them to your slow cooker. Add the 4 cups of beef broth, 1 cup of white wine, and 1 teaspoon of thyme. Season with salt and pepper to taste.
- Stir the mixture well to combine all the ingredients. Cover the slow cooker with its lid and set it to cook on low for 8 hours. This slow cooking process allows the flavors to meld beautifully.
- Once the cooking time is complete, taste the soup and adjust the seasoning if necessary. If you prefer a richer flavor, you can add a bit more salt or thyme at this stage.
- While the soup is finishing, preheat your oven to 350°F (175°C). Place the 6 slices of baguette on a baking sheet and toast them in the oven for about 10 minutes, or until they are golden and crispy.
- After toasting, remove the baguette slices from the oven and top each slice with a generous amount of shredded Gruyère cheese, about 1/4 cup per slice.
- Return the cheese-topped baguette slices to the oven and bake for an additional 5 to 7 minutes, or until the cheese is melted and bubbly.
- To serve, ladle the hot French onion soup into bowls and float a cheese-topped baguette slice on top of each serving. Enjoy your slow-cooked French onion soup!
Tips
- Slice with Care: For the best texture and flavor, slice your onions as thinly as possible. A mandoline slicer can be a great tool for achieving uniform slices.
- Low and Slow: Patience is key when caramelizing onions. Allow them to cook slowly on low heat to develop their natural sweetness and rich color.
- Quality Broth: Use a high-quality beef broth for the best flavor. Homemade broth can elevate your soup to the next level.
- Wine Matters: Choose a good white wine that you would enjoy drinking. The flavor of the wine will significantly impact the final taste of your soup.
- Cheese Choices: While Gruyère is traditional, you can mix in other cheeses like Swiss or provolone for a unique twist.
- Toast for Texture: Toast the baguette slices until they are crispy to prevent them from becoming soggy in the soup.
- Garnish with Fresh Herbs: A sprinkle of fresh thyme or parsley just before serving can add a pop of color and freshness to your dish.
- Adjust to Taste: Don’t hesitate to tweak the seasoning to your preference. A dash of balsamic vinegar can add depth, while a pinch of cayenne can introduce a subtle heat.By following these tips, you'll ensure that your French Onion Soup is not only delicious but also a delightful experience for you and your guests!
