Ingredients

• 2 Yellow Onion (thinly sliced)
• 2 lb Chuck Roast (cut into 2‑inch cubes)
• 2 Tbsp Unsalted Butter (cut into small pieces)
• 6 cup Beef Broth (low‑sodium preferred)
• 2 Tbsp Worcestershire Sauce
• 1/2 tsp Black Pepper (freshly ground)
• 2 cup Water
• 1 French Baguette (sliced 1/2‑inch thick)
• 1 cup Gruyère Cheese (shredded)
• 2 clove Garlic (minced (optional))

Instructions

1. Slice the onions

   Trim the ends off the yellow onions and slice them as thinly as possible (about 1‑2 mm) using a sharp chef’s knife.

2. Add onions to the slow cooker

   Transfer the sliced onions to the bottom of the crock‑pot, spreading them evenly.

   Time: PT2M

3. Prepare and add the chuck roast

   Cut the chuck roast into 2‑inch cubes, then add the pieces on top of the onions.

   Time: PT5M

4. Add butter (and optional garlic)

   Drop 2 Tbsp of unsalted butter (and minced garlic, if using) over the meat and onions; the butter will melt during cooking.

   Time: PT2M

5. Add liquids and seasonings

   Pour in 6 cups beef broth, 2 Tbsp Worcestershire sauce, 1/2 tsp freshly ground black pepper, and 2 cups water. Stir gently to combine.

   Cover the slow cooker, set it to HIGH, and cook for about 6 hours (or until the beef is fork‑tender).

   Time: PT6H

7. Shred the beef

   When the cooking time is up, remove the lid, use two forks to pull the beef apart into bite‑size shreds, and stir them back into the soup.

   Time: PT5M

8. Toast the baguette slices

   Preheat the oven broiler to high. Place baguette slices on a baking sheet and toast for 3‑5 minutes until lightly golden.

   Time: PT5M

   Temperature: Broil

9. Assemble the soup bowls

   Ladle hot soup into oven‑safe bowls, place one or two toasted baguette slices on top, and sprinkle generously with shredded Gruyère cheese.

• Broil the cheese just until bubbly to avoid burning.

Chef Tips from the Video

• Add a splash of dry sherry or brandy to the broth for a classic French flavor.
• For extra depth, caramelize a portion of the onions in a skillet before adding them to the crock‑pot.
• Use a high‑quality aged Gruyère for the best melt and flavor.
