Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

1 (1.5 lb) beef roast (such as rump roast or chuck roast)

1 packet ranch dressing mix (optional, for seasoning)

1 packet au jus gravy mix

1 cup beef broth

12 slider buns (or small sandwich rolls)

1 cup sliced provolone cheese (or your preferred cheese)

1/4 cup mayonnaise (optional for spreading on buns)

2 tbsp butter, melted (for brushing on buns)

1 tbsp garlic powder (optional for extra flavor)

Directions
Prepare the Roast: Place the beef roast in a slow cooker. Sprinkle the ranch seasoning mix (if using) and the au jus gravy mix over the roast. Pour in the beef broth. Cover and cook on low for 6–8 hours, or until the beef is tender and easy to shred.

Shred the Beef: Remove the cooked roast from the slow cooker. Using two forks, shred the meat and discard any excess fat. Return the shredded beef to the slow cooker to absorb the flavorful juices.

Prepare the Buns: Preheat the oven to 375°F (190°C). Slice the slider buns and arrange the bottom halves on a baking sheet. If desired, spread a thin layer of mayonnaise on the insides of the buns.

Assemble the Sandwiches: Distribute the shredded beef evenly across the bun bottoms. Top with provolone cheese slices.

Toast the Buns: Place the top halves of the buns on each sandwich. Brush with melted butter and sprinkle garlic powder over the tops for added flavor.

Bake: Bake for 10–15 minutes, or until the cheese has melted and the tops of the buns are golden brown.

Serve: Slice into individual sandwiches and serve warm. Offer extra au jus from the slow cooker as a dipping sauce, if desired.

Calories: Approximately 300 kcal per sandwich

Variations
Spicy Kick: Add sliced jalapeños or pepper jack cheese for heat.

Different Cheese Options: Swap provolone for Swiss, cheddar, or mozzarella.

Sweet Touch: Use Hawaiian sweet rolls for a contrast in flavor.

Herbed Butter: Mix herbs into the melted butter for extra seasoning before brushing on buns.

Grilled Option: Instead of oven baking, grill the assembled sandwiches for a crispier exterior.

Storage/Reheating
Storage: Store leftover sandwiches in an airtight container in the refrigerator for up to 3 days.

Reheating: To reheat, place sandwiches on a baking sheet and warm in a 350°F (175°C) oven for 10 minutes. Alternatively, microwave individual portions for 1–2 minutes, though the buns may soften.

Freezing: You can freeze the shredded beef separately for up to 2 months. Thaw overnight in the refrigerator and assemble fresh before serving.

FAQs
Can I use a different cut of beef?
Yes, chuck roast or even brisket works well as long as it’s suitable for slow cooking and becomes tender when shredded.

Do I have to use the ranch seasoning?
No, the ranch mix is optional. You can omit it for a more traditional roast beef flavor.

Can I cook the beef faster?
Cooking on high for 3–4 hours is possible, but low and slow yields the most tender results.

What if I don’t have a slow cooker?
You can cook the beef in a covered Dutch oven at 300°F (150°C) for 3–4 hours or until tender.

Can I make this ahead of time?
Yes, you can cook the beef a day ahead. Store in the refrigerator and reheat before assembling the sandwiches.

What type of cheese melts best for this recipe?
Provolone, Swiss, and mozzarella melt smoothly and pair well with roast beef.

Are these sandwiches good for meal prep?
Yes, prepare the beef and buns in advance and reheat portions as needed.

Can I add vegetables to the sandwiches?
Absolutely. Sautéed onions, bell peppers, or even mushrooms add great flavor and texture.

What’s a good side dish for these sandwiches?
Serve with coleslaw, potato salad, chips, or a simple green salad.

Is it okay to skip baking them in the oven?
Yes, you can serve them directly after assembly, but baking enhances the flavor and texture.
