Why you’ll love this dish

This sandwich is the kind of comfort food you can set and forget. A chuck roast becomes richly flavored with just beef broth and onion soup mix, so the prep is minimal and the payoff is maximum. It is budget-friendly, kid-approved, and perfect for busy evenings, game day spreads, or casual weekend lunches.

"Tender beef that melts into the roll and a jus you actually want to dip into twice. Simple, slow, and utterly satisfying."

Reasons to choose this recipe:

• Very little hands-on time. Set the slow cooker and go.
• Uses inexpensive beef cut that becomes tender with low, slow cooking.
• Easy to scale for a crowd.
• Kid-friendly with familiar flavors from onion soup and melted provolone.

Step-by-step overview

You start by seasoning the roast and placing it in the slow cooker. Then whisk the beef broth with an onion soup mix and pour it over the meat. Slow-cook until the beef is fork-tender, shred it, and let it soak up the juices. To serve, pile the shredded beef on hoagie rolls, top with provolone, and offer the au jus for dipping. The whole process is forgiving, so small timing variations do not ruin the result.

What you’ll need

• 2 pounds beef chuck roast (a boneless roast works well)
• 1 can (10.5 ounces) beef broth
• 1 packet onion soup mix
• 6 hoagie rolls
• 6 slices provolone cheese
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Ingredient notes:

• If you prefer a richer au jus, use low-sodium beef broth and adjust salt at the end.
• For a cheesier melt, swap provolone for Swiss or fontina.
• Rolls: sturdy hoagies hold up best to dipping.

Step-by-step instructions

1. Pat the chuck roast dry with paper towels. Season all over with salt and pepper.
2. Place the roast in the slow cooker, fat side up.
3. In a bowl, whisk the beef broth and onion soup mix until combined. Pour the mixture over the roast.
4. Cover and cook on low for 8 hours or on high for 4 hours. The beef is done when it shreds easily with two forks.
5. Remove the roast and transfer it to a cutting board. Use two forks to shred the meat into bite-size pieces.
6. Return the shredded beef to the slow cooker and stir so it soaks up the juices for a few minutes. Taste and adjust seasoning.
7. To assemble, split each hoagie roll and pile on sliced beef. Top each with a slice of provolone. Serve warm with the au jus in small bowls for dipping.

Best ways to enjoy it

Serve these sandwiches hot with the au jus on the side so everyone can dip to taste. Toasting the cut sides of the rolls under a broiler for 1 to 2 minutes adds crunch and helps the bread stand up to the juicy beef. Pair with simple sides like crispy fries, a green salad with vinaigrette, or oven-roasted carrots. If you want a matching flavor profile for a party platter, try serving alongside savory bites like French Onion Meatballs for a unified onion-forward theme.

Storage and reheating tips

Refrigeration: Store leftover shredded beef and au jus in airtight containers. Refrigerate within two hours of cooking and use within 3 to 4 days.
Freezing: Cool completely, then place beef and au jus in freezer-safe containers or heavy-duty freezer bags. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Warm beef and au jus gently on the stovetop over low to medium heat until steaming. Aim for an internal temperature of 165°F before serving. Reheat sandwiches in a 350°F oven for 8 to 10 minutes or until the cheese melts. Avoid reheating at very high heat which can dry the meat.

Pro chef tips

• Sear the roast in a hot skillet for 2 to 3 minutes per side before slow cooking if you want extra browning and depth of flavor. This is optional but worth the few extra minutes.
• Slice or shred the beef against the grain for a more tender bite.
• If the au jus is watery, remove some cooking liquid, simmer it on the stovetop to reduce and concentrate flavor, then pour back over the beef.
• To melt the cheese perfectly, place assembled sandwiches under the broiler for 30 to 60 seconds—watch closely to prevent burning.

Creative twists

• Mushroom and onion: Add sliced mushrooms and extra onions to the slow cooker for an earthy boost.
• Spicy kick: Stir in a teaspoon of hot sauce or a pinch of red pepper flakes into the au jus.
• Slider version: Serve on small rolls for party-friendly sliders.
• Vegetarian option: Replace beef with large portobello mushrooms or shredded jackfruit braised in beef-flavored vegetable broth and onion seasoning for a similar texture and flavor profile.

Common questions

How long does prep take and what is total time?

Prep is about 10 minutes. Cook time is 8 hours on low or 4 hours on high, so total time depends on your slow cooker setting.

Can I use a different cut of beef?

Yes. Eye of round or bottom round can work, but chuck roast is preferred because it becomes especially tender with slow cooking. Leaner roasts may be drier, so plan to cook with slightly more liquid or on a lower temperature for longer.

How do I thicken the au jus if it is too thin?

Remove a cup of the au jus and simmer it down to concentrate the flavor. For a slightly thicker sauce, whisk in a cornstarch slurry (1 teaspoon cornstarch mixed with 1 tablespoon cold water) and simmer until it thickens. Add small amounts at a time so it does not become too heavy.

Is it safe to keep the shredded beef in the slow cooker on warm overnight?

It is better to refrigerate leftovers within two hours of cooking. While many slow cookers have warm settings, leaving food at warm temperatures for prolonged periods can increase food safety risks.

Can I make this ahead for a party?

Yes. Cook the roast a day ahead, shred it, and store the beef and au jus separately in the refrigerator. Reheat gently on the stovetop and assemble sandwiches just before serving for the best texture.
