There’s something irresistibly comforting about a warm, crusty sandwich filled with tender, juicy beef and topped with melty cheese — especially when it’s served with a rich, savory au jus for dipping. That’s exactly what you get with these Slow Cooker French Dip Sandwiches. I love making these on a chilly weekend or even during the week when I want dinner to be hands-off but still totally satisfying.

This recipe leans heavily on the slow cooker to do all the heavy lifting — hours of low-and-slow cooking transform a humble chuck roast into shredded perfection, soaking up all the flavors of beef broth, garlic, onions, and Worcestershire sauce. All you have to do is layer it into a French roll, top it with provolone or mozzarella, and toast it until golden. Dip, bite, repeat. Pure bliss.

Why You’ll Love This Slow Cooker French Dip Sandwiches Recipe

These sandwiches check every box when it comes to comfort food: juicy meat, melty cheese, crusty bread, and rich dipping sauce. They’re low effort thanks to the slow cooker, but taste like something you’d get at a cozy diner. Plus, they make incredible leftovers.

What Kind of Bread Should I Use for French Dip Sandwiches?

The best choice is a crusty French roll or hoagie roll that holds up well to the juicy filling and dipping sauce. Look for rolls with a sturdy exterior and soft interior. Baguettes also work, though they can be a bit tougher to bite into. Avoid soft sandwich bread, as it will fall apart in the au jus.

Options for Substitutions

If you don’t have chuck roast, you can use bottom round roast or brisket, though they may be slightly leaner and less tender. Swiss cheese can replace provolone if you prefer a nuttier flavor. For a low-carb version, skip the bread and serve the meat and cheese in lettuce wraps with au jus on the side.

Ingredients for This Slow Cooker French Dip Sandwiches Recipe

Chuck Roast: This is the star of the dish. Chuck roast becomes beautifully tender and easy to shred after hours in the slow cooker, absorbing all the savory broth flavors.

Beef Broth: Acts as the flavorful liquid base for both cooking the meat and creating the dipping sauce (au jus).

Yellow Onion: Adds natural sweetness and depth to the au jus as it softens during cooking.

Garlic: Infuses the meat and broth with an aromatic kick that enhances all the savory notes.

Worcestershire Sauce: Brings a rich umami boost that mimics the flavor complexity of traditional French dip.

Soy Sauce: Deepens the saltiness and adds extra savory depth.

Bay Leaf: A small touch that gives the au jus a subtle earthy warmth.

Provolone Cheese: Melts perfectly over the hot shredded beef, adding creaminess and stretch.

French Rolls or Hoagie Buns: Strong enough to hold up to the moisture from the meat and dipping sauce.

Butter (optional): For toasting the bread, which adds a golden crunch and rich flavor.

Fresh Parsley (optional): Adds a pop of freshness and color when sprinkled on top.

Step 1: Prep the Roast and Vegetables

Trim any large pieces of fat off the chuck roast, but don’t go overboard — some fat is essential for flavor. Slice the onion into thin strips and mince the garlic. Set aside.

Step 2: Layer Ingredients into the Slow Cooker

Place the onions and garlic in the bottom of the slow cooker. Place the chuck roast on top. Pour in the beef broth, Worcestershire sauce, and soy sauce. Toss in a bay leaf for extra depth of flavor.

Step 3: Cook Low and Slow

Set your slow cooker to low and cook for 8 to 10 hours. You want the beef to be fall-apart tender and easy to shred with two forks. If you’re short on time, cook on high for 4 to 5 hours, but the longer cooking method delivers better flavor.

Step 4: Shred the Beef

Once the roast is done, remove it from the slow cooker and shred it using two forks. Skim excess fat off the surface of the au jus. Return the shredded meat to the pot to soak up more flavor.

Step 5: Toast and Assemble the Sandwiches

Split the French rolls and butter them if desired. Toast under a broiler or in a hot pan until golden and crispy. Pile the shredded beef onto the bottom half of each roll, top with provolone, and place under the broiler until the cheese melts.

Step 6: Serve with Au Jus

Ladle the warm au jus from the slow cooker into small bowls. Serve each sandwich with a bowl of the dipping sauce for the full French Dip experience.

How Long to Prepare the Slow Cooker French Dip Sandwiches

Prep Time: You’ll need about 15 to 20 minutes at the start. That includes trimming the roast, slicing the onion, mincing garlic, and assembling everything in the slow cooker. Toasting the buns and assembling the sandwiches at the end takes an additional 10 minutes.

Cook Time: On low, the roast needs 8 to 10 hours for optimal tenderness. If you’re pressed for time, cooking it on high for 4 to 5 hours still yields good results. The slow, low cook is worth it though — the meat becomes unbelievably tender and soaks up all the flavors.

Tips for Perfect Slow Cooker French Dip Sandwiches

Sear the Roast (Optional): For deeper flavor, you can sear the roast on all sides in a hot skillet before adding it to the slow cooker.
Toast the Bread Well: A good crunchy exterior keeps the bread from getting soggy when dipped in au jus.
Use a Fat Separator: If your broth is too oily, separate the fat from the au jus before serving.
Melt Cheese in the Oven: After assembling, pop the sandwiches under the broiler for that golden, bubbly cheese finish.
Don’t Overfill: Keep the sandwich fillings balanced so they’re easy to handle and dip without falling apart.

Watch Out for These Mistakes While Cooking

Using Lean Cuts of Beef: Leaner roasts like eye of round won’t shred easily and may turn out dry.
Under-seasoning the Broth: Don’t skimp on Worcestershire or soy sauce; they add critical depth to the au jus.
Skipping Toasting: Untoasted rolls will soak too much liquid and become soggy.
Overcooking on High: High heat for too long can lead to dry, stringy meat instead of juicy shreds.
Not Shredding the Beef Properly: Use forks or meat claws to pull the beef into thick shreds for the best texture.

What to Serve With Slow Cooker French Dip Sandwiches?

1. Crispy French Fries

A classic pairing with any sandwich, especially when you want something to dip alongside that au jus.

2. Simple Green Salad

Something light and refreshing to balance the richness of the meat and cheese.

3. Roasted Vegetables

Carrots, zucchini, and bell peppers tossed in olive oil and herbs are perfect on the side.

4. Coleslaw

Adds a crunchy, creamy contrast to the warm sandwich.

5. Pickles or Pickled Onions

A tangy addition that cuts through the richness and enhances the flavors.

Storage Instructions

Refrigeration: Store leftover shredded beef and au jus separately in airtight containers. They will keep in the fridge for up to 4 days. Reheat the beef in some of the au jus to keep it juicy.

Freezing: The beef freezes beautifully. Place shredded beef and some of the au jus in a freezer-safe container and freeze for up to 3 months. Thaw in the fridge overnight and reheat gently on the stovetop.

Bread Storage Tip: Always store the bread separately to prevent it from getting soggy. Toast fresh before assembling again.
