Full Ingredients

Beef & Aromatics

• 3 lb boneless beef chuck roast, trimmed of thick exterior fat
• 2 tsp kosher salt
• 1 tsp freshly ground black pepper
• 1 tbsp neutral oil (canola, avocado, or grapeseed)
• 2 large yellow onions (about 1.5 lb total), halved and thinly sliced
• 6 garlic cloves, smashed
• 6 fresh thyme sprigs (or 1.5 tsp dried thyme)
• 2 bay leaves (optional)

Braising Liquid & Au Jus

• 4 cups low-sodium beef broth
• 1 tbsp Worcestershire sauce
• 1 tbsp soy sauce
• Optional finishing: 1 tsp sherry or red wine vinegar; 1 tbsp unsalted butter

For Serving

• 8 hoagie rolls (6-inch), split
• 2 tbsp unsalted butter, melted (for toasting rolls)
• 8 slices provolone cheese (about 8 oz)
• Optional: prepared horseradish or creamy horseradish sauce; chopped parsley for garnish

Step-by-Step Instructions

Step 1: Season and sear the roast

Pat the chuck roast dry. Sprinkle all over with 2 teaspoons kosher salt and 1 teaspoon black pepper. Heat 1 tablespoon oil in a large skillet over medium-high heat until shimmering. Sear the roast for 3–4 minutes per side (and 1–2 minutes on edges) until a deep brown crust forms. This browning builds flavor for the au jus.

Step 2: Load the slow cooker

Place the sliced onions, smashed garlic, and thyme (and bay leaves if using) in the slow cooker. Nestle the seared roast on top. Pour in 4 cups beef broth, 1 tablespoon Worcestershire, and 1 tablespoon soy sauce. The liquid should come at least halfway up the sides of the roast.

Step 3: Slow-cook until shreddable

Cover and cook on LOW for 8 hours, or on HIGH for 4.5 hours, until the beef is fork-tender and strands pull apart easily. If using LOW, resist lifting the lid for the first 6 hours to maintain steady heat.

Step 4: Shred the beef and strain the juices

Transfer the roast to a cutting board and rest 10 minutes. Meanwhile, strain the cooking liquid through a fine-mesh sieve into a saucepan; press on the onions to extract flavorful juices. Skim off surface fat. Using two forks, shred the beef into chunky strands, discarding any large fatty bits.

Step 5: Reduce and season the au jus

Bring the strained liquid to a lively simmer over medium-high heat and reduce for 10–12 minutes, until you have about 3 cups. Taste and adjust: add a pinch of salt if needed and stir in 1 teaspoon sherry vinegar to brighten. For extra richness, whisk in 1 tablespoon cold butter off heat.

Step 6: Toast rolls, melt cheese, and serve

Preheat the oven to 425°F. Brush the cut sides of the rolls with 2 tablespoons melted butter and arrange cut-side up on a sheet pan. Toast for 5 minutes until lightly crisp. Pile warm shredded beef onto the rolls and top each with a slice of provolone. Return to the oven for 2–3 minutes, until the cheese is just melted. Ladle about 1/2 cup hot au jus into small bowls for each serving. Serve immediately, dunking each bite into the jus.

Pro Tips

• Brown well: a deep sear on the roast means a deeper, richer au jus later.
• Control the salt: use low-sodium broth, then season the reduced jus at the end.
• Reduce for intensity: a quick 10-minute simmer concentrates beefy flavor and gives the jus body.
• Keep it crisp: thoroughly toast the rolls so they stay sturdy when dunked.
• Cheese as “glue”: melting provolone over the beef helps hold everything in place.

Variations

• French Onion Style: caramelize the onions in 1 tbsp butter until deeply golden before adding to the slow cooker; finish the jus with a splash (2 tbsp) of dry sherry and use Gruyère cheese.
• Spicy Italian Dip: add 1 cup sliced pepperoncini plus 2 tbsp brine to the cooker; finish sandwiches with provolone or mozzarella and a spoon of giardiniera.
• Herb & Garlic Boost: add 1 sprig fresh rosemary and an extra 2 cloves garlic to the cooker for a more aromatic profile.

Storage & Make-Ahead

Refrigerate shredded beef and au jus (stored separately or together) in airtight containers for up to 4 days. For longer storage, freeze up to 3 months. Reheat gently in a saucepan, bringing the jus and beef to a simmer until piping hot (165°F). Toast fresh rolls and melt cheese just before serving. Pro move: make the beef a day ahead and chill; the fat will solidify on the jus for easy removal, yielding a cleaner, richer dip.
