The Key Ingredients for Perfect French Dip
The magic of these sandwiches lies in the simplicity and quality of the ingredients. You don’t need a long list of fancy items to create a deeply flavorful au jus and tender beef. Here’s what you’ll need to make the best Slow Cooker French Dip Sandwiches.
What’s the Best Cut of Beef?
For the best results, a beef chuck roast is the gold standard. It has fantastic marbling, which means more flavor and moisture as it cooks. The slow cooking process melts this fat and collagen, creating incredibly tender meat. A rump roast or sirloin roast are also excellent alternatives if you prefer a slightly leaner option.
Building the Perfect Au Jus
The soul of a French dip is the au jus. We build layers of flavor starting with a rich beef broth. A combination of onion, garlic, and a hint of Worcestershire sauce creates a savory base that perfectly complements the beef. Don’t be tempted to use water; a quality broth is non-negotiable for a truly epic dip.

How to Make Slow Cooker French Dip Sandwiches (Step-by-Step)
Making these sandwiches is as easy as 1-2-3. We’ll guide you through each simple step to ensure your French dip is absolutely perfect.
- Sear the Beef: Pat the chuck roast dry and season generously with salt and pepper. Sear all sides in a hot, oiled skillet until a deep brown crust forms. This step is crucial for developing rich, complex flavor.
- Slow Cook: Place the seared roast in the slow cooker. Add the beef broth, sliced onions, garlic, and Worcestershire sauce. Cover and cook on low for 8 hours or on high for 4 hours, until the beef is fall-apart tender.
- Assemble the Sandwiches: Remove the beef from the slow cooker and shred it using two forks. Strain the cooking liquid (the au jus) into a bowl. Lightly toast your hoagie rolls, pile them high with the shredded beef, top with provolone cheese, and broil for 1-2 minutes until the cheese is melted and bubbly. Serve immediately with a side of the warm au jus for dipping.
Tips for the Best French Dip Every Time
Want to take your Slow Cooker French Dip Sandwiches from great to unforgettable? Follow these simple tips from our kitchen.
- Don’t Skip the Sear: Searing the roast before slow cooking creates the Maillard reaction, which adds a massive layer of savory depth to both the meat and the au jus.
- Toast Your Buns: A critical step! Toasting the hoagie rolls prevents them from becoming soggy when you add the beef and dip the sandwich. A quick broil or a toast in a buttered pan works perfectly.
- Strain the Au Jus: For a smooth, clean dipping sauce, be sure to strain the onions and any solids out of the cooking liquid before serving. You can even use a fat separator for a less greasy jus.
- Choose Quality Rolls: Sturdy hoagie rolls, French baguettes, or ciabatta rolls are best. They need to be robust enough to hold the juicy beef and withstand a good dip in the au jus without falling apart. This is a great tip for other hearty sandwiches, like our Bacon-Wrapped Grilled Cheese.

What to Serve with French Dip Sandwiches
While these sandwiches are a meal in themselves, a few classic sides can complete the experience. Consider serving them with crispy french fries, a simple green salad with a vinaigrette, or some creamy coleslaw. For a more comforting meal, our Crockpot Broccoli Cheddar Potato Soup (coming soon) makes an excellent partner.
Variations and Customizations
Feel free to make this recipe your own! Add sliced bell peppers and mushrooms to the slow cooker for a Philly-style French dip. A splash of red wine or a dark beer in the broth can add another layer of complexity. For a bit of a kick, add a pinch of red pepper flakes to the au jus.
Storing and Reheating Leftovers
Leftovers are fantastic! Store the shredded beef and the au jus in separate airtight containers in the refrigerator for up to 4 days. To reheat, simply warm the beef and au jus gently in a saucepan over medium-low heat. You can then assemble the sandwiches as if you were making them fresh.
Frequently Asked Questions
While it’s difficult, it is possible. If cooked for too long, the beef can become mushy rather than tender-shredded. Sticking to the recommended 8 hours on low or 4 hours on high typically yields the perfect texture.
To prevent soggy bread, it’s essential to toast the hoagie rolls before assembling the sandwiches. A quick trip under the broiler or in a buttered pan creates a barrier that helps the bread hold up to the juicy beef and au jus.
The best cut is a beef chuck roast due to its excellent marbling, which becomes incredibly tender and flavorful during the slow cooking process. A rump roast is a great leaner alternative.
‘Au jus’ is a French term that means ‘with juice’. In this recipe, the au jus is the flavorful liquid that the beef cooks in, which is essentially enriched beef broth infused with drippings from the meat, onion, and garlic.
Provolone is the classic choice for French Dip because it melts beautifully and has a mild flavor that complements the beef. Swiss cheese is another popular and delicious option.

Equipment
Method
- Pat the chuck roast dry with paper towels and season all over with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Carefully place the roast in the skillet and sear for 4-5 minutes per side, until a deep brown crust forms.
- Transfer the seared roast to the basin of a large slow cooker. Add the sliced onion, minced garlic, beef broth, and Worcestershire sauce. Cover and cook on LOW for 8 hours or on HIGH for 4 hours, until the beef is tender and shreds easily with a fork.
- Carefully remove the beef from the slow cooker and place it on a large cutting board. Use two forks to shred the meat. Strain the liquid from the slow cooker through a fine-mesh sieve into a bowl or saucepan; this is your au jus. Discard the solids.
- Preheat your broiler. Open the hoagie rolls and place them on a baking sheet. Toast them lightly under the broiler for 1-2 minutes. Pile the shredded beef onto the bottom half of each roll, top with a slice of provolone cheese, and broil for another 1-2 minutes until the cheese is melted and bubbly. Place the top of the roll on and serve immediately.
- Serve the sandwiches hot with small bowls of the warm au jus for dipping.
Notes
Au Jus: For a richer flavor, you can simmer the strained au jus on the stovetop for 10-15 minutes to reduce it slightly.
