The first time I made these Slow Cooker French Dip Sandwiches, I couldn’t believe how effortless they were. The aroma of seasoned beef slowly cooking all day while I went about my routine was already a win—but then came the juicy, melt-in-your-mouth meat piled high on a toasted roll, with gooey melted cheese and that glorious, savory au jus for dipping.

Why You’ll Love These Slow Cooker French Dip Sandwiches

These sandwiches deliver all the flavor with none of the stress. The slow cooker does the heavy lifting—tenderizing the beef and infusing it with rich, beefy goodness—while you sit back and relax. The combination of crusty bread, juicy shredded beef, melty cheese, and warm au jus is nothing short of irresistible. They’re also super versatile, easily doubling for a crowd or perfect for meal prep.

What Cut of Beef Should I Use?

Chuck roast is hands-down the best option for French dip sandwiches. It’s well-marbled, flavorful, and breaks down beautifully in the slow cooker. If chuck roast isn’t available, bottom round roast or even brisket can work in a pinch, though they may need a little longer to get that fall-apart texture.

Options for Substitutions

• Bread: Hoagie rolls are the classic choice, but French baguettes or ciabatta rolls also hold up well to the juiciness.
• Cheese: Provolone is a favorite, but Swiss, mozzarella, or even a sharp white cheddar can melt beautifully and complement the beef.
• Broth: While beef broth is the base of the au jus, adding a splash of Worcestershire sauce or soy sauce can deepen the flavor.
• Onions: Sautéed onions add a sweet-savory layer, but you can skip them or replace with caramelized shallots for a twist.
• Butter: Toasting the buns with a swipe of garlic butter takes the sandwich to another level, though it’s optional if you’re short on time.

Ingredients for These Slow Cooker French Dip Sandwiches

• Chuck Roast: This is the star of the show. It’s rich, marbled, and turns incredibly tender after hours in the slow cooker.
• Beef Broth: The base for the flavorful au jus. Choose low-sodium to better control the saltiness.
• Worcestershire Sauce: Adds depth and umami to the broth.
• Soy Sauce: Balances the broth with savory saltiness.
• Garlic: A few cloves infuse the meat and broth with bold flavor.
• Yellow Onion: Sliced onions soften and sweeten during cooking, adding complexity to the au jus.
• Dried Thyme & Bay Leaf: These aromatics bring subtle earthiness and fragrance.
• Salt & Pepper: Essential for seasoning the roast.
• Provolone Cheese: Melts perfectly over the warm beef, giving that classic cheesy pull.
• Hoagie Rolls or French Bread: The sandwich base—hearty enough to soak up the au jus without falling apart.
• Butter (optional): For toasting the rolls and adding a layer of flavor.

Step 1: Season and Sear the Beef

Generously season the chuck roast with salt and pepper. If you have time, sear it in a hot skillet with a little oil until browned on all sides. This step is optional but adds deep, savory flavor to the meat and broth.

---

Step 2: Layer Ingredients in the Slow Cooker

Place sliced onions and garlic at the bottom of the slow cooker. Lay the roast on top. Pour in the beef broth, Worcestershire sauce, and soy sauce. Add the thyme and bay leaf. Cover and cook on low for 8 hours, or on high for 4-5 hours, until the beef is fall-apart tender.

---

Step 3: Shred the Beef

Remove the cooked roast and shred it using two forks. Discard any large pieces of fat. Strain the broth to remove onions and herbs if you prefer a cleaner au jus.

---

Step 4: Toast the Rolls

While the beef is resting, slice the rolls and lightly butter the insides. Toast them in a skillet or under the broiler until golden and crisp.

---

Step 5: Assemble the Sandwiches

Pile the shredded beef onto each toasted roll. Top with slices of provolone cheese and return to the oven or broiler just long enough to melt the cheese.

---

Step 6: Serve with Au Jus

Ladle the warm strained broth into small bowls for dipping. Serve each sandwich hot with a side of au jus and enjoy every savory, cheesy bite.

How Long to Prepare the Slow Cooker French Dip Sandwiches

Prep Time: You’ll need about 15–20 minutes to get everything ready—seasoning the roast, slicing onions and garlic, and possibly searing the meat. Prepping the rolls and cheese at the end also takes just a few minutes.

Cook Time: On low, the roast needs 8 hours to become fall-apart tender, while the high setting will shorten it to around 4–5 hours. Slow and low is the way to go for maximum flavor and tenderness.

Tips for Perfect Slow Cooker French Dip Sandwiches

• Sear the Meat: It’s optional, but a good sear on the roast enhances the flavor tenfold.
• Use a Fat Separator: If your au jus turns out a bit greasy, skim the fat or use a separator to make it clean and sippable.
• Toast the Bread: This adds crunch and prevents sogginess when dipped in the broth.
• Melt Cheese Properly: Let the cheese melt in the oven, not just on the hot beef, for that bubbly, golden finish.
• Use Fresh Bread: The crustier the roll, the better it will hold up to dipping.

Watch Out for These Mistakes While Cooking

• Undercooking the Roast: Chuck roast needs time to break down—rushing it leads to tough meat.
• Using Salty Broth: Always go with low-sodium to keep control over seasoning.
• Skipping the Sear: If you have 5 extra minutes, sear that roast. It adds amazing depth.
• Overloading the Sandwiches: Piling too much meat can cause the bread to fall apart while dipping.
• Forgetting to Strain the Au Jus: It’s more enjoyable when it’s smooth and free of stray herbs or onions.
