If you enjoy New Orleans Cajun food, you will love this Roast Beef Po Boy. It is a great way to use your leftover roast beef.  This post includes instructions to building a fabulous Cajun Roast Beef Po Boy plus a delicious slow cooker roast beef.

Roast Beef Po Boy Cajun New Orleans Style

A Po Boy is a traditional Louisiana sandwich.  It consists of roast beef or fried seafood like shrimp, crab, oysters, or fish.  New Orleans French Bread is a must for Po Boys. It has a crispy crust and a soft fluffy center.

A New Orleans Roast Beef Po Boy starts cooking the roast beef low and slow in the oven.  Cajuns make a delicious gravy out of the dripping from the roast and add small pieces of the roast into the gravy.  They serve this Debris on a New Orleans Roast Beef Debris Po-Boy.

The bread they serve the Po Boy on is always French bread.  You usually get a six or twelve inch Po Boy. They slice the French bread lengthwise. Generously, add mayonnaise on the top and bottom part of the bread.  My husband likes to add a little horseradish on one side. Next, they layer cheese, Swiss cheese generally, on one side of the French Bread.  Next, cover the cheese with a generous portion of hot roast beef debris.

On the other side of the Roast Beef Po Boy, they add shredded lettuce and fresh slices of tomato with salt, pepper, and Cajun Seasoning.  It is incredibly messy and typically requires a knife and fork instead of picking it up.  Messy or not, a New Orleans Roast Beef Po Boy is out of this world.  The bread absorbs a lot of the gravy, and it is genuinely yumminess.

For my homemade version of a Roast Beef Po Boy, I cook the roast beef on low for ten hours in a slow cooker.

Second Step: Your Slow Cooker Roast

Next, I chop it up into small pieces and make a gravy using the incredibly tasty broth the roast cooked in.  New Orleans Gravy is thinner than the gravy I make.  It is a must to use the liquid from the roast to make the gravy.

Third Step: Bread

Fourth Step: Mayonnaise

Fifth Step: Cheese & Roast Beef

Sixth Step: Make the Gravy

Seventh Step: Add the Gravy and Toppings

Do Not Skip The Gravy

After layering the Swiss cheese and adding the roast beef, I add the gravy to the chopped roast.  It is a little less messy this way, but I serve additional broth from the slow cooker.  This way, you can dip the sandwiches into it.  This Roast Beef Po Boy can still be messy, but it is so worth it.  It is finger, licking good.
