Making Slow Cooker Ground Beef French Dip Sandwiches is straightforward. Just follow these steps:

1. Prepare Ground Beef: In a skillet, brown the ground beef over medium heat. Drain excess grease and set aside.

2. Combine Ingredients: In the slow cooker, combine browned ground beef, diced onion, minced garlic, beef broth, Worcestershire sauce, thyme, black pepper, salt, and soy sauce. Stir until the mixture is well blended.

3. Cook: Cover the slow cooker and set it to low for 8 hours or high for 4 hours. Allow the flavors to meld beautifully.

4. Prepare Rolls: When the cooking time is nearly complete, preheat your oven to 350°F (175°C). Split rolls or baguettes in half and lightly toast them.

5. Fill Rolls: Once cooked, use a slotted spoon to fill each toasted roll with the beef mixture. If desired, top with slices of provolone or Swiss cheese.

6. Melt Cheese: Place the filled rolls on a baking sheet and return them to the oven for about 5 minutes or until cheese is melted and bubbly.

7. Serve with Au Jus: Ladle the remaining cooking liquid from the slow cooker into small bowls for dipping and serve alongside the sandwiches.

These steps will help you create an irresistible platter of deliciousness that everyone will enjoy.
