What is a French Dip Sandwich?
A French Dip Sandwich is a classic American sandwich made with thinly sliced beef, typically served on a French roll or hoagie bun, and accompanied by a rich, flavorful au jus (a beef broth-based dipping sauce). The beef is often slow-cooked to tender perfection, allowing the flavors to develop and the meat to shred easily. The sandwich is then assembled with cheese and served alongside the au jus for dipping, making every bite juicy and savory.
The Origin of the French Dip Sandwich
Though its exact origin is debated, the French Dip Sandwich is commonly believed to have been created in Los Angeles in the early 20th century. One theory credits the sandwich to Philippe’s, a local restaurant that served a French roll filled with roast beef and au jus to a police officer, who accidentally dropped his sandwich into the beef juices. The result was so delicious that it became a signature item, and the French Dip was born. Another theory points to the Clifton’s Cafeteria, where a similar creation was said to be introduced.
Regardless of its origin, the French Dip Sandwich has become a beloved American comfort food, known for its savory, tender beef and satisfying dipping experience.
Ingredients for Slow Cooker French Dip Sandwiches
For the Beef:
- 3–4 lb chuck roast
- 1 medium onion, sliced
- 3 cups beef broth
- ¼ cup soy sauce
- 2 tablespoons Worcestershire sauce
- 1 tablespoon balsamic vinegar (optional, adds depth)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- ½ teaspoon black pepper
- 2 bay leaves
For the Sandwiches:
- 6–8 French rolls or hoagie rolls
- 6–8 slices provolone or Swiss cheese
- Butter (optional for toasting)
Step-by-Step Directions for Slow Cooker French Dip Sandwiches

1. Prep the Slow Cooker
Start by placing the sliced onions in the bottom of your slow cooker. These will infuse the beef with their flavor as it cooks. Next, place the chuck roast on top of the onions.
2. Make the Broth
In a separate bowl, whisk together the following ingredients to create the flavorful broth that will cook the beef:
- Beef broth
- Soy sauce
- Worcestershire sauce
- Balsamic vinegar (optional but recommended for added depth of flavor)
- Garlic powder
- Onion powder
- Dried thyme
- Dried rosemary
- Black pepper
Once everything is well combined, pour this broth mixture over the chuck roast and add the bay leaves to enhance the flavor further.
3. Cook the Beef
Now it’s time to cook the beef:
- Low for 8–10 hours for the best texture and tenderness.
- High for 4–5 hours if you’re short on time.
The beef should be incredibly tender and easy to shred once it’s done. The long, slow cooking process ensures that all the flavors meld together perfectly.
4. Shred the Beef
After the beef has cooked, carefully remove the bay leaves. Take the roast out of the slow cooker and shred it using two forks. The meat should fall apart easily, thanks to the long cooking time. Once shredded, return the beef to the broth and let it soak for an additional 10–15 minutes to absorb even more flavor.
5. Toast the Sandwiches
While the beef soaks in the broth, it’s time to prepare the sandwiches:
- Lightly butter your French rolls or hoagie rolls and toast them on a skillet, griddle, or under the broiler. This adds a crispy texture and enhances the flavor.
- Once toasted, pile on a generous amount of the shredded beef.
- Top the beef with provolone or Swiss cheese slices.
- Melt the cheese either under the broiler or in the skillet for a gooey, delicious result.
6. Serve With Au Jus
Finally, strain the cooking liquid from the slow cooker and serve it in small bowls alongside your sandwiches. This au jus is perfect for dipping the sandwiches and soaking up all the savory juices.
Tips & Variations
- Onion Lovers: If you love onions, consider caramelizing some extra onions and adding them to your sandwich for a rich, sweet flavor.
- Spicy Version: Add sliced pepperoncini or a splash of their brine to give the sandwich a little kick.
- Extra Richness: For a more indulgent dip, stir 1 tablespoon of butter into the au jus after straining it.
- Gluten-Free: If you need a gluten-free version, use gluten-free rolls and ensure the soy sauce and broth are gluten-free.
Frequently Asked Questions
1. Can I use a different cut of beef?
While chuck roast is ideal for slow cooking due to its marbling and tenderness, you can use other cuts like brisket or round roast. Just be aware that the texture and flavor may differ slightly.
2. How can I make the sandwich spicier?
To add a bit of heat to your French Dip, you can include spicy ingredients like jalapeños, pepperoncini, or a drizzle of hot sauce. You could also opt for a spicy cheese like pepper jack.
3. Can I make this recipe ahead of time?
Yes! In fact, the beef will be even more flavorful if you prepare it the night before. Just refrigerate the shredded beef and broth overnight, and when you’re ready to serve, reheat everything and assemble your sandwiches.
4. Can I freeze leftover French Dip?
Yes, you can freeze the leftover beef and broth for up to 3 months. Simply let it cool, then store in an airtight container. To reheat, just thaw it in the fridge overnight and heat it up on the stove or in the microwave.
