Ingredients You’ll Need
· 1 (3 to 4 lb) beef chuck roast
· 1 (1 oz) packet dry au jus gravy mix
· 2 cups beef broth
For Serving:
· 6 French or hoagie rolls, buttered and toasted
· Optional toppings: sliced provolone or Swiss cheese, sautéed onions, sautéed mushrooms, horseradish sauce, sliced pepperoncini
Note: For a gluten-free version, ensure au jus mix is gluten-free and serve on gluten-free rolls. For extra flavor, sear the roast before slow cooking. Chuck roast is ideal for its marbling, but rump roast or bottom round also work.
Step-by-Step Instructions
- Place Roast in Slow Cooker: Place the beef chuck roast in the bottom of the slow cooker. No need to cut or trim it—the roast will shred easily after cooking.
- Add the Au Jus Mixture: In a small bowl, whisk together the dry au jus mix and the beef broth until the powder is fully dissolved. Pour the mixture over the roast, ensuring it’s mostly submerged in the liquid.
- Cook Low and Slow: Cover and cook on LOW for 8-9 hours or HIGH for 5-6 hours, until the meat is incredibly tender and falls apart easily with a fork. The long cooking time is what makes the beef so tender and flavorful.
- Shred the Beef: Carefully remove the roast from the slow cooker and place it on a cutting board. Use two forks to shred it into bite-sized pieces, discarding any excess fat. The meat should fall apart effortlessly.
- Prepare the Au Jus: Strain the remaining juices from the slow cooker into a small bowl to remove any bits of fat. This is your rich, incredible au jus for dipping. If you prefer a thicker jus, whisk 1 tablespoon cornstarch with 2 tablespoons cold water, stir into the juices, and cook on HIGH for 10 minutes until thickened.
- Toast the Rolls: Butter the French or hoagie rolls and toast them under the broiler or in a skillet until golden and crispy. This prevents the bread from becoming soggy when dipped.
- Assemble the Sandwiches: Pile the shredded meat generously onto the buttered, toasted rolls. Add cheese or other toppings if desired.
- Serve with Au Jus: Serve immediately with the hot au jus on the side for dipping. Encourage everyone to dip generously—that’s the best part!
Tips for the Best Slow Cooker French Dip Sandwiches
· Sear the Roast (Optional): For extra depth of flavor, sear the roast in a hot skillet with a little oil for 3-4 minutes per side before placing in the slow cooker. This creates a caramelized crust that adds richness to the au jus.
· Use Chuck Roast: This cut has the perfect amount of marbling and connective tissue that breaks down during slow cooking, resulting in tender, flavorful beef. Avoid lean cuts that can become dry.
· Don’t Rush the Cooking: The long cooking time is essential for tender beef. LOW for 8-9 hours produces the best results.
· Toast the Rolls Well: Toasted, buttered rolls hold up better to dipping and add a delicious crunch.
· Add Cheese: Provolone or Swiss cheese melts beautifully over the hot beef. Add it during the last few minutes of toasting for a melty finish.
· Strain the Au Jus: Straining removes excess fat and creates a cleaner, more flavorful dipping sauce.
Variations & Substitutions
· Cheesy French Dip: Add sliced provolone or Swiss cheese to the sandwiches and broil briefly until melted.
· Philly Style French Dip: Add sautéed onions, bell peppers, and mushrooms to the sandwich. Use provolone cheese.
· Spicy Version: Add 1/4 teaspoon red pepper flakes to the au jus mixture. Serve with pepperoncini or spicy horseradish sauce.
· Onion French Dip: Add 1 sliced onion to the slow cooker with the roast for extra flavor.
· Garlic French Dip: Add 3-4 cloves minced garlic to the au jus mixture.
· Italian French Dip: Add 1 teaspoon Italian seasoning and 1/2 teaspoon garlic powder to the au jus. Serve with giardiniera.
Frequently Asked Questions
Can I use a different cut of beef?
Yes! Chuck roast is ideal for its marbling and tenderness, but rump roast, bottom round, or brisket also work well. Avoid lean cuts like sirloin tip, which can become dry during long cooking.
Can I cook this on high instead of low?
Yes, cook on HIGH for 5-6 hours instead of LOW for 8-9 hours. The beef should still be fork-tender and easy to shred.
Can I make this in an Instant Pot?
Absolutely! Use the sauté function to sear the roast. Add au jus mixture. Cook on high pressure for 60 minutes, then natural release for 15 minutes. Shred and serve.
How do I store leftovers?
Store the shredded beef and au jus separately in airtight containers in the refrigerator for up to 4 days. Reheat the beef in the au jus to keep it moist and flavorful.
Can I freeze this dish?
Yes! Freeze the shredded beef in the au jus in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave.
What can I serve with French dip sandwiches?
Serve with French fries, potato chips, coleslaw, a simple green salad, or roasted vegetables. Pickles and potato salad also pair beautifully.
Why is my beef tough?
This usually means it hasn’t cooked long enough. Chuck roast needs time for the connective tissue to break down. Cook on LOW for at least 8 hours, or until the meat easily shreds with a fork.
Can I make the au jus thicker?
Yes, whisk 1 tablespoon cornstarch with 2 tablespoons cold water to create a slurry. Stir into the hot juices and cook on HIGH for 10-15 minutes until thickened.
