How to Make Cajun Roast Beef Po’ Boys Step-by-Step
Step 1: Brown the Beef
Heat oil in a large oven-safe pan over medium-high heat. Season the beef roast with 1 tablespoon Cajun seasoning. Brown the beef on all sides until a crust forms.
Step 2: Add Onions and Liquids
Add the sliced onions, beef broth, Worcestershire sauce, and remaining Cajun seasoning to the pan.
Step 3: Cook the Beef
You have several options:
- Stovetop: Bring to a boil, reduce heat to low, cover, and simmer 2-4 hours until beef is fork-tender.
- Oven: Preheat to 275°F (140°C), cover pan, and cook 2-4 hours until tender.
- Slow Cooker: Place everything in the slow cooker and cook on LOW for 8-10 hours or HIGH for 4-6 hours.
Step 4: Shred the Beef
Remove the beef and shred it using two forks.
Step 5: Make the Gravy
Bring the cooking liquid to a boil. Mix cornstarch and water to create a slurry, then add it to the liquid. Reduce heat and simmer until gravy thickens, about 2-3 minutes.
Step 6: Combine Beef and Gravy
Mix the shredded beef back into the thickened gravy until well coated.
Step 7: Assemble the Po’ Boys
Slice the hoagie rolls and spread mayonnaise on the insides. Pile on the shredded beef mixture, then add shredded lettuce, tomato slices, and pickles.
Step 8: Serve and Enjoy!
Serve immediately for the best flavor and texture. Optionally, add hot sauce for extra heat.
