Ingredients

• 500 grams Beef chuck or stewing beef
• 4 large Yellow onions
• 3 cloves Garlic
• 3 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 2 tablespoons All-purpose flour
• 6 cups Beef broth
• 1 cup Red wine
• 1 piece Bay leaf
• 1 teaspoon Thyme
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 6 pieces Baguette slices
• 1.5 cups Gruyère cheese

Directions

Step 1

Cut the beef into bite-sized cubes and set aside.

Step 2

Peel the onions and slice them thinly. Mince the garlic.

Step 3

In a large pot or Dutch oven, heat 1 tablespoon of olive oil and 1 tablespoon of butter over medium heat.

Step 4

Add the beef and sear until browned on all sides. Remove the beef from the pot and set it aside.

Step 5

In the same pot, lower the heat to medium-low and add the remaining 2 tablespoons of butter.

Step 6

Add the sliced onions and cook, stirring frequently, for about 25-30 minutes until deeply caramelized.

Step 7

Stir in the minced garlic and cook for 1-2 minutes until fragrant.

Step 8

Sprinkle the flour over the onions and stir well to coat. Cook for 1-2 minutes to eliminate the raw flour taste.

Step 9

Deglaze the pot by adding the red wine, scraping up any browned bits from the bottom.

Step 10

Return the seared beef to the pot, then pour in the beef broth.

Step 11

Add the bay leaf, thyme, salt, and black pepper. Bring the soup to a simmer.

Step 12

Cover the pot partially and let the soup simmer gently for 1 hour, stirring occasionally. Adjust seasoning if needed.

Step 13

While the soup is simmering, preheat the oven to 375°F (190°C). Toast the baguette slices on a baking sheet until crispy.

Step 14

Top each baguette slice with grated Gruyère cheese and return to the oven until the cheese is melted and bubbly, about 5 minutes.

Step 15

Serve the soup hot, ladled into bowls, and topped with the cheesy baguette slices.
