Ingredients
Scale
Beef and Seasoning
- 2-3 pounds beef roast (chuck or eye of round)
- 1 tablespoon Cajun seasoning
- 1 tablespoon oil (for searing)
Cooking Liquids and Gravy
- 1 medium onion (sliced or diced)
- 1-2 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 tablespoon cornstarch
- 1 tablespoon water (to dissolve cornstarch)
Sandwich Assembly
- 6 12-inch hoagies/buns
- 6 tablespoons mayonnaise (for spreading)
- 2 cups shredded lettuce (for crunch)
- 2 large tomatoes (sliced)
- 1/2 cup sliced pickles (for tang)
Instructions
- Brown the Beef: Heat the oil in a large oven-safe pan over medium-high heat. Coat the beef roast evenly with 1 tablespoon Cajun seasoning, then add it to the hot pan. Sear the roast, browning all sides to lock in the flavors and develop a savory crust.
- Add Cooking Aromatics and Liquid: Add the sliced or diced onion to the pan alongside the beef. Pour in 1 to 2 cups of beef broth and 1 tablespoon Worcestershire sauce. Sprinkle another tablespoon of Cajun seasoning over the mixture. Stir gently to combine and bring the liquid to a gentle boil, ensuring all flavors meld.
- Simmer the Beef: Reduce the heat to low, cover the pan, and let the beef simmer slowly until tender, which takes about 2 to 4 hours on the stovetop. Alternatively, place the pan in a preheated oven at 275°F (135°C) or transfer all ingredients to a slow cooker set on LOW and cook for 8 to 10 hours. The result is tender, shreddable beef packed with flavor.
- Shred the Beef: Once tender, remove the beef from the pan and shred it finely using two forks. Set aside the shredded meat while you prepare the gravy with the remaining liquid.
- Prepare Gravy: Bring the leftover cooking liquid in the pan to a boil over medium heat. In a small bowl, dissolve 1 tablespoon of cornstarch in 1 tablespoon of water to make a slurry. Stir the slurry into the boiling liquid, continuing to stir until it thickens, about 2 to 3 minutes, creating a rich, flavorful gravy.
- Combine Beef and Gravy: Return the shredded beef to the thickened gravy, mixing thoroughly to coat the meat and keep it moist and juicy.
- Assemble the Po’ Boys: Spread each hoagie bun with 1 tablespoon of mayonnaise, then fill generously with the beef mixture. Top with shredded lettuce, sliced tomatoes, and pickles to add crunch and tangy brightness to each sandwich.
Notes
- For even richer flavor, marinate the beef roast with Cajun seasoning overnight.
- If using a slow cooker, sear the beef beforehand as directed for best texture and flavor.
- Adjust the amount of beef broth based on desired gravy consistency; add more if you prefer a thinner gravy.
- Serve immediately to enjoy the bread fresh and the meat warm.
- Leftover shredded beef can be refrigerated for up to 3 days or frozen for up to 3 months.
