Total Time: 6 hrs 15 mins
Cuisine: French
Serves: 8 servings
Ingredients
- 4 large onions, sliced
 - 2 lbs beef chuck, cubed
 - 8 cups beef broth
 - 1 cup red wine
 - 1 tsp thyme
 - Salt and pepper to taste
 - 8 slices of baguette
 - 2 cups shredded Gruyere cheese
 
Instructions
- Peel and slice the onions thinly, ensuring uniform thickness for even cooking.
 - Season the beef chuck cubes generously with salt and black pepper, ensuring each piece is well-coated.
 - Heat a large skillet over medium-high heat and brown the beef cubes on all sides, creating a rich caramelized exterior. This step will enhance the soup's depth of flavor.
 - Transfer the browned beef cubes to the slow cooker.
 - In the same skillet, sauté the sliced onions until they become soft and start to caramelize, approximately 8-10 minutes.
 - Add the caramelized onions to the slow cooker with the beef cubes.
 - Pour in the beef broth and red wine, then sprinkle dried thyme over the mixture.
 - Cover the slow cooker and set it to low heat, cooking for 6 hours until the beef becomes tender and the flavors meld together.
 - About 30 minutes before serving, preheat the oven's broiler.
 - Ladle the soup into oven-safe bowls, ensuring each serving has beef and onions.
 - Top each bowl with a slice of baguette and generously sprinkle shredded Gruyere cheese over the bread.
 - Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted, bubbly, and slightly golden brown.
 - Carefully remove from the broiler and let cool for a few minutes before serving.
 - Garnish with fresh thyme leaves if desired, and serve hot.
 
Tips
- Slice onions uniformly to ensure even caramelization and cooking.
 - Take your time browning the beef - this step is crucial for developing deep, rich flavors.
 - Use a good quality beef broth and red wine for the best taste profile.
 - Don't rush the slow cooking process; low and slow is the key to tender beef and melded flavors.
 - Choose a high-quality Gruyere cheese for the most authentic and delicious topping.
 - Watch the broiler carefully when melting the cheese to prevent burning.
 - Let the soup rest for a few minutes after broiling to allow flavors to settle and prevent burning your mouth.
 - Fresh thyme leaves can add an extra layer of aromatic freshness as a final garnish.
