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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Combine Beef and Gravy: Return the shredded beef to the thickened gravy, mixing thoroughly to coat the meat and keep it moist and juicy.
  7. 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.
