Step‑by‑Step Instructions for Cajun Roast Beef Po Boy

Step 1: Heat the Oil
In a large oven-safe pan, heat a few tablespoons of oil over medium-high heat until shimmering. This crucial first step ensures your Cajun Roast Beef gets that beautiful, crispy exterior. As the oil heats, gather your ingredients and make sure your beef roast is ready to be seasoned.

Step 2: Season and Sear the Beef
Generously rub the beef roast with Cajun seasoning, ensuring it’s well-coated. Carefully place the seasoned roast in the hot oil, browning it on all sides for about 5-7 minutes until it develops a golden crust. You’ll know it’s ready to turn when it releases easily from the pan, creating a mouthwatering aroma in your kitchen.

Step 3: Add Aromatics and Liquids
Once the beef is browned, add diced onions to the pan, sautéing them for about 3-4 minutes until they become translucent. Then pour in the beef broth and Worcestershire sauce, followed by additional Cajun seasoning to boost the flavor. Stir everything together to create a savory base for your roast beef.

Step 4: Choose Your Cooking Method
Now, decide your cooking method for the Cajun Roast Beef. For stovetop, bring the mixture to boil, reduce heat to low, cover, and simmer for 2-4 hours until fork-tender. If using the oven, cover the pot and cook in a preheated oven at 275°F for the same duration. Alternatively, for a slow cooker, transfer all ingredients, cover, and cook on LOW for 8-10 hours or HIGH for 4-6 hours.

Step 5: Shred the Beef
Once the beef is tender and can be easily pulled apart, remove it from the pot and place it onto a cutting board. Let it rest for a few minutes before using two forks to shred the beef into bite-sized pieces, allowing all the flavorful juices to soak in.

Step 6: Thicken the Gravy
Using the cooking liquid left in the pan, bring the mixture to a rapid boil on the stovetop. Mix together cornstarch and water in a small bowl to create a slurry, then whisk it into the boiling liquid. Reduce the heat and simmer for 2-3 minutes until the gravy thickens to a luscious consistency, perfect for your po boys.

Step 7: Combine Beef and Gravy
Add the shredded beef back into the thickened gravy, ensuring it’s fully coated. Stir gently to combine, allowing the meat to soak in all the rich flavors from the gravy. This mixture will be the hearty filling for your Cajun Roast Beef Po Boys.

Step 8: Assemble the Po Boys
To construct your Cajun Roast Beef Po Boys, take soft hoagies and generously fill them with the beef mixture. Top with mayonnaise, crisp lettuce, fresh tomato slices, and optional pickles for that tangy crunch. If you like a bit of heat, consider drizzling on some hot sauce.

Step 9: Serve and Enjoy
Your Cajun Roast Beef Po Boys are now ready to serve! Arrange them on a platter, and feel free to pair with crispy fries or coleslaw for a complete meal. Each bite promises a delightful experience of tender beef and zesty toppings, perfect for sharing with family and friends.

Make Ahead Options

These Cajun Roast Beef Po Boys are perfect for meal prep enthusiasts! You can season and sear the beef up to 24 hours in advance, allowing the flavors to meld beautifully. Simply marinate the beef roast in Cajun seasoning, then brown it and store it in the refrigerator. You can also chop the vegetables and prepare the gravy up to 3 days ahead; just refrigerate them separately to maintain their freshness. When you’re ready to enjoy your po boys, cook the marinated beef using your chosen method until it’s fork-tender. Reheat the gravy, combine with the shredded beef, and assemble your po boys for a comforting meal that feels just as special as if you made it all at once!

Expert Tips for Cajun Roast Beef Po Boys

Marinate for Flavor: Marinate the beef in Cajun seasoning overnight to enhance the flavors and tenderize the meat for a more robust dish.
Ensure Even Browning: Avoid common mistakes by ensuring the beef is turned frequently during the initial sear, achieving that golden crust.
Check for Tenderness: Test the beef for fork-tenderness; overcooking can dry it out, so keep an eye on your cooking time!
Thicken Wisely: When thickening the gravy, whisk the cornstarch slurry in gradually—this prevents clumping in your Cajun Roast Beef Po Boy.
Bread Choice Matters: Use fresh, soft hoagies for the best texture; stale bread won’t hold the moist filling or provide a satisfying bite.

How to Store and Freeze Cajun Roast Beef Po Boys

Fridge: Store leftover Cajun Roast Beef in an airtight container for up to 3 days to maintain freshness. Reheat gently on the stovetop or in the microwave.

Freezer: Place cooled leftover roast beef in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

Gravy Storage: The gravy can also be stored separately in the fridge for up to 3 days or frozen for 2 months. Reheat on the stovetop until warmed through.

Sandwich Assembly: It’s best to assemble the po boys just before serving. Store hoagies and fillings separately to keep the bread from getting soggy.
