Slow Cooker 3-Ingredient French Dip Sandwiches

These Slow Cooker 3-Ingredient French Dip Sandwiches are an easy, delicious way to enjoy tender, slow-cooked beef with very little preparation. A juicy beef chuck roast is cooked slowly in a flavorful combination of beef broth and onion soup mix until it becomes incredibly soft and easy to shred.

As the beef cooks, it absorbs all the rich, savory flavors while creating a delicious homemade au jus for dipping. Served on toasted hoagie rolls and paired with the warm cooking juices, these sandwiches bring restaurant-style comfort right to your kitchen.

Perfect for busy weekdays, relaxed weekends, or feeding a hungry family, this simple slow cooker recipe delivers big flavor with just three main ingredients.

Ingredients

For the Beef and Au Jus

• 3–4 lb beef chuck roast, trimmed
• 3 cups low-sodium beef broth
• 2 packets (1 oz each) dry onion soup mix

For Serving

• 6 hoagie rolls or submarine sandwich buns

Instructions

Step 1: Prepare the Beef

Place the beef chuck roast inside a 5–7-quart slow cooker with the fat side facing upward. Sprinkle the onion soup mix evenly over the roast, gently pressing it onto the surface of the meat. Pour the beef broth around the sides of the roast.

Keeping the fatty side facing up allows the fat to gradually render during cooking, helping keep the beef moist and flavorful.

Step 2: Slow Cook Until Tender

Cover the slow cooker with its lid and cook using one of the following settings:

• LOW: 8–10 hours.
• HIGH: 4–5 hours.

The beef is ready when it becomes fork-tender and can easily be pulled apart. Cooking times may vary depending on the size and thickness of the roast.

Step 3: Shred the Beef

Carefully transfer the cooked roast to a large bowl or cutting board. Use two forks to pull the meat apart into tender, bite-sized shreds.

Skim any excess fat from the cooking liquid. Return the shredded beef to the slow cooker and stir gently so the meat is coated in the flavorful juices. Leave on the WARM setting for another 10–15 minutes to allow the beef to absorb even more of the savory broth.

Step 4: Assemble the Sandwiches

Slice the hoagie rolls and generously fill each one with the warm shredded beef.

For an extra-crispy finish, arrange the assembled sandwiches on a baking sheet and place them under the broiler for approximately 2–3 minutes, just until the bread becomes lightly toasted and the edges turn golden. Watch carefully to prevent burning.

Serve immediately with small bowls of the warm au jus on the side for dipping.

Helpful Tips

• Choose chuck roast: This cut becomes especially tender during long, slow cooking and produces flavorful shredded beef.
• Don’t rush the cooking: Allow enough time for the roast to become completely fork-tender.
• Remove excess fat: Skimming the cooking liquid before returning the shredded beef helps create a cleaner, richer dipping sauce.
• Toast the rolls: Lightly crisping the bread helps prevent it from becoming soggy when filled with juicy beef.
• Add extra toppings: Swiss cheese, provolone, or caramelized onions make delicious additions if you want to customize your sandwiches.

Serving Suggestions

Pair these hearty French dip sandwiches with:

• Crispy French fries or seasoned potato wedges.
• Creamy homemade coleslaw.
• A fresh garden salad.
• Pickles or tangy pepperoncini.
• Roasted vegetables or onion rings.

Storage and Reheating

• Refrigerator: Store leftover shredded beef and au jus together in an airtight container for up to 3–4 days.
• Freezer: Freeze the beef with some of its cooking liquid for up to 3 months.
• Reheating: Warm gently in a saucepan over medium-low heat or microwave until thoroughly heated. Add a little broth if needed to maintain moisture.
