Total Time: 6 hrs 10 mins
Cuisine: American
Serves: 6 servings
Ingredients
- 4 large onions, thinly sliced
- 2 cloves garlic, minced
- 4 cups beef broth
- 1 cup beer (lager or ale)
- 2 tbsp Worcestershire sauce
- 1 tsp thyme
- Salt and pepper to taste
- 1 cup shredded cheese (Gruyere or Swiss)
- 6 slices of baguette
Instructions
- Begin by preparing the onions. Peel and thinly slice the 4 large onions. Aim for uniform slices to ensure even cooking.
- In a large skillet over medium heat, add a tablespoon of oil (optional) and sauté the sliced onions. Stir occasionally until they become soft and translucent, about 10-15 minutes. This step enhances the flavor of the onions.
- Once the onions are softened, add the 2 cloves of minced garlic to the skillet. Stir for another minute until fragrant, being careful not to let the garlic burn.
- Transfer the sautéed onions and garlic into the slow cooker. This will be the base for your soup.
- Pour in 4 cups of beef broth, followed by 1 cup of beer (lager or ale). The beer will add depth and richness to the soup.
- Add 2 tablespoons of Worcestershire sauce and 1 teaspoon of thyme to the slow cooker. Season with salt and pepper to taste. Stir all the ingredients together to combine well.
- Cover the slow cooker and set it to low heat. Allow the soup to cook for 6 hours. This slow cooking process will develop the flavors beautifully.
- After 6 hours, check the seasoning of the soup. Adjust salt and pepper if needed.
- While the soup is finishing, preheat your oven to 350°F (175°C). Arrange the 6 slices of baguette on a baking sheet.
- Toast the baguette slices in the preheated oven for about 10 minutes, or until they are golden brown and crispy.
- Once the soup is ready, ladle it into bowls. Top each serving with a generous amount of shredded cheese (Gruyere or Swiss) and place under the broiler for 2-3 minutes, or until the cheese is melted and bubbly.
- Serve the soup hot, garnished with the toasted baguette slices on the side or floated on top of the soup.
Tips
- Onion Slicing Technique: Use a sharp knife and slice onions uniformly to ensure even caramelization and cooking.
- Beer Selection Matters: Choose a good quality lager or ale. The beer's flavor will significantly impact the soup's overall taste, so select one you'd enjoy drinking.
- Caramelization is Key: Take time to slowly sauté onions before adding to the slow cooker. This step develops a deeper, sweeter flavor profile.
- Cheese Recommendation: While Gruyere or Swiss are traditional, don't be afraid to experiment with other melting cheeses like Emmental or Comté.
- Toasting Baguette: For extra flavor, brush baguette slices with garlic-infused olive oil before toasting for added depth.
- Low and Slow: Resist the urge to rush the cooking process. The 6-hour slow cooking time allows flavors to meld beautifully.
- Make Ahead Friendly: This soup tastes even better the next day, so consider making it in advance for enhanced flavor development.
