Ingredients
Scale
Beef and Cooking Liquid
- 1 tablespoon vegetable oil (or any neutral oil with high smoke point)
- 3 to 4 pound chuck roast
- 1 and 1/2 teaspoons kosher salt (use 1 teaspoon if table salt)
- 1 teaspoon black pepper
- 2 and 1/2 cups water
- 1/4 cup sherry wine
- 1 tablespoon Better Than Bouillon Beef Base
- 1 bay leaf
- 2 (1 oz) packets dry onion soup mix
- 1/2 teaspoon dried thyme (or 1 sprig fresh thyme)
- 1/2 teaspoon dried rosemary (or 1 sprig fresh rosemary)
Sandwich Components
- 6 to 8 crusty rolls (ciabatta, sub rolls, or similar)
- 1/2 cup butter (softened) (optional)
- 1/2 teaspoon garlic powder (optional)
- 16 ounces provolone cheese (sliced; can substitute Monterey Jack or mozzarella)
- 1 batch Horseradish Sauce (for serving)
Instructions
- Season and Dry Roast: Heat a wide skillet over medium-high heat. Pat the chuck roast dry and sprinkle evenly with 1 and 1/2 teaspoons kosher salt (or 1 teaspoon table salt). This ensures a good sear and enhances flavor.
- Heat Oil: Add 1 tablespoon vegetable oil to the hot skillet, swirling to coat the bottom. It should shimmer immediately if the pan is properly heated.
- Sear the Roast: Place the roast in the pan and do not move it for 1-2 minutes to develop a brown crust. Use tongs to flip and brown all sides of the roast thoroughly, about 5-6 minutes total.
- Transfer to Slow Cooker: Place the seared roast in a 6-quart (or larger) slow cooker. Sprinkle 1 teaspoon black pepper over the roast.
- Make Broth: Return the skillet to medium heat. Add 2 and 1/2 cups water, 1/4 cup sherry wine, and 1 tablespoon beef base. Stir well, scraping browned bits off the pan until the beef base dissolves. Pour this liquid over the roast in the slow cooker.
- Add Bay Leaf: Place 1 bay leaf into the slow cooker for herbal aroma.
- Season with Onion Soup Mix: Sprinkle 2 packets of dry onion soup mix directly onto the top of the roast. Rub it into the exposed meat with your hand; some may fall into the broth, which is fine.
- Add Herbs: Sprinkle 1/2 teaspoon dried thyme and 1/2 teaspoon dried rosemary over the roast, or add fresh sprigs if available.
- Slow Cook: Cover and cook on low heat for 8-10 hours until the meat is fork-tender. Alternatively, use high heat for 1 hour before switching to low. Avoid cooking on high all the way through to maintain tenderness.
- Rest Roast: Carefully remove the tender roast from the slow cooker to a cutting board with a juice groove. Let it rest for a few minutes.
- Slice Meat: Using a sharp chef’s knife, slice the roast against the grain into thick slices, avoiding shredding as much as possible. Keep the sliced meat warm.
- Prepare Oven and Rolls: Preheat the broiler and move the oven rack to the top position. Slice rolls if not pre-sliced and place them face-up on a baking sheet.
- Optional Garlic Butter: Mix 1/2 cup softened butter with 1/2 teaspoon garlic powder and spread on cut sides of rolls for extra flavor and moisture.
- Broil Rolls (First Side): Under the broiler, toast the rolls cut side up for 2-3 minutes until golden and crisp. Watch closely to avoid burning.
- Broil Rolls (Second Side): Flip rolls over and broil the other side for 2-4 minutes until nicely crisp but not burned.
- Add Cheese and Melt: Flip rolls back to cut-side up, layer with sliced provolone cheese, and return to broiler for 1-2 minutes until the cheese just melts.
- Assemble Sandwiches: Spread horseradish sauce on the cheesy rolls, top with sliced beef, and close the sandwich.
- Serve with Au Jus: Ladle warm au jus broth from the slow cooker into small bowls. Dip each sandwich before taking a hearty bite for full French Dip experience.
Notes
- Adjust salt quantities if using table salt instead of kosher to avoid over-salting.
- For more tender meat, avoid cooking entirely on high heat in the slow cooker.
- Using fresh rosemary and thyme instead of dried herbs enhances flavor if available.
- The optional garlic butter adds richness and flavor but can be omitted to reduce calories.
- Broil rolls carefully and watch the toasting process closely to prevent burning.
- Leftover au jus can be refrigerated for up to 3 days and reheated for dipping.
