Ingredients
Scale
Beef and Seasoning
- 1 (2.5 to 3-pound) beef chuck roast
- 1 (1-ounce) packet au jus mix
- 1 (0.87-ounce) packet brown gravy mix
- 1 cup water
Bread and Toppings
- 4 to 6 French bread sub rolls (about 6 inches each) or 2 large French bread loaves cut into 2 to 3 pieces each
- Finely shredded cabbage
- Dill pickle chips
- Mayo
- Yellow mustard
- Creole mustard
Instructions
- Prepare the Slow Cooker: Spray the crock of a 4 to 6-quart slow cooker with nonstick cooking spray to prevent sticking. Place the beef chuck roast inside the crock.
- Mix and Add Seasonings: In a small bowl, whisk together the au jus mix, brown gravy mix, and 1 cup of water until fully combined. Pour this seasoned liquid over the beef roast in the slow cooker to ensure the meat stays moist and flavorful during cooking.
- Cook the Roast: Cover the slow cooker and set it to cook on low for 8 to 10 hours. This long, slow cooking breaks down the tough beef connective tissue, making the meat tender and easy to shred.
- Shred the Beef: Once the roast is very tender, carefully remove it from the slow cooker. Allow it to cool enough to handle safely, then shred the beef with two forks. Discard any large pieces of fat. Return the shredded meat to the slow cooker and stir to coat it evenly with the remaining gravy and juices.
- Warm the Bread: Preheat the oven to 400°F (204°C). Place the French bread rolls or pieces on a baking sheet and warm them in the oven for 3 to 5 minutes until the exterior crisps slightly, enhancing texture for the sandwich.
- Assemble the Po’ Boys: Spread mayo and Creole mustard and/or yellow mustard inside the warmed bread for a zesty, creamy base. Pile generous amounts of shredded beef debris with its gravy onto the bread. Top the beef with finely shredded cabbage and dill pickle chips to add crunch and brightness to each bite.
- Serve: Serve the assembled Roast Beef Debris Po’ Boys immediately while warm to enjoy the full savory flavors and satisfying textures characteristic of this New Orleans classic.
Notes
- Using a chuck roast is ideal because its marbling breaks down slowly for tender meat perfect for shredding.
- Adjust mustard types and quantities to suit your preferred spice and tang levels.
- Shredded cabbage adds a crunchy texture contrast but you can substitute with coleslaw mix if desired.
- If you prefer a saucier sandwich, add more cooking liquid from the slow cooker when assembling.
- French bread is traditional, but sturdy hoagie rolls or baguettes can also work well.
- Cook time can vary slightly based on slow cooker model; ensure beef is tender enough to shred easily.
