Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
3 pounds round roast, trimmed of excess fat
2 cups low-sodium beef broth
2 tablespoons Worcestershire sauce
1 teaspoon dried parsley flakes
1 teaspoon dried basil
1 teaspoon Italian seasoning
1 teaspoon garlic powder
1 teaspoon onion salt
1/2 teaspoon salt
1/2 teaspoon black pepper
6 hoagie rolls, split
6 slices provolone or mozzarella cheese, optional
1/2 cup sliced pepperoncini or banana peppers, optional
Directions
Take the roast out of the refrigerator about 1 hour before cooking so it can lose some of its chill. Trim any visible excess fat, then place the roast in the slow cooker.
In a small bowl, combine the dried parsley flakes, basil, Italian seasoning, garlic powder, onion salt, salt, and black pepper. Sprinkle the seasoning mixture evenly over the roast.
In a measuring cup or bowl, stir together the beef broth and Worcestershire sauce. Pour this mixture around and over the roast in the slow cooker.
Cover and cook on low for 6 to 7 hours, or until the roast is tender and reaches a safe internal temperature. For a more shredded texture, continue cooking until the beef pulls apart easily, which may take up to 8 or 9 hours depending on the size and thickness of the roast.
Once the roast is tender, remove it carefully and slice it thinly or shred it with two forks. Return the beef to the slow cooker and let it sit in the broth for 30 minutes on low so it can soak up even more flavor.
Pile the beef onto hoagie rolls. Add cheese or peppers if desired. Spoon some of the cooking liquid into small bowls and serve it as au jus for dipping.

Variations
For a cheesier sandwich, melt provolone or mozzarella over the warm beef before serving. If you like a little tang and heat, add sliced pepperoncini or banana peppers. For a larger presentation, serve the beef on a loaf of French bread and slice it into portions for sharing. You can also toast the hoagie rolls with a little garlic butter for extra flavor and texture. If you prefer a bolder herb taste, add a pinch of dried oregano or a little crushed red pepper.
Storage/Reheating
Store leftover beef and au jus together in an airtight container in the refrigerator for up to 3 days. Keeping the beef in the broth helps prevent it from drying out.
To reheat, place the beef and some of the au jus in a saucepan over low heat until warmed through. You can also microwave it in short intervals, stirring in between, until hot. If the broth reduces too much, add a splash of extra beef broth.
For longer storage, freeze the cooled beef and au jus in a freezer-safe container or bag for up to 1 month. Thaw overnight in the refrigerator before reheating.
FAQs
Can I use a different cut of beef?

Can I make this recipe ahead of time?
Yes, the beef tastes even better after sitting in the au jus, so it is a great make-ahead meal.
Is it better to slice or shred the roast?
Either works. Slice it for a deli-style sandwich or shred it for a softer, juicier filling.

How do I keep the sandwiches from getting soggy?
Use a slotted spoon to add the beef to the rolls and serve the au jus on the side for dipping.

Potato chips, fries, mashed potatoes, or a simple salad all pair nicely.
