Are you looking for a well-seasoned roast beef that is so tender it falls apart?  This Slow Cooker Roast Beef was cooked on low for ten hours in a slow cooker.  It reminds me of New Orleans Roast Beef Debris.

In New Orleans, they make Roast Beef Debris for Roast Beef Po Boys, Roast Beef & Gravy over a Baked Potato, Roast Beef & Gravy over Fries or even over a hamburger.  I will be adding all these recipes soon.

We lived on the Northshore of New Orleans for several years.  I remember the first time I heard the word Debris (pronounced Day-bree) when someone was talking about a roast.  I had no idea what they were talking about.  I just figured Debris is another New Orleans word.  It is obvious to the locals you are not from the New Orleans area if you do not know what debris is.  

Cook Your Roast Low And Slow

To make Debris, you cook a roast low and slow until it completely falls apart.  Roast Beef Debris is cooked in the oven.  The bits and pieces from the roast are added to the gravy.  This combination is called Debris.  In the New Orleans area, you will find Roast Beef Debris over fries, hamburgers and more.  My favorite place to eat Roast Beef Debris is at Bear’s Restaurant.  They have a hamburger covered in Debris and Debris covered French Fries which are very messy, but amazingly delicious. 

Best Way To Prepare Roast Is In Slow Cooker

I have found that the best way prepare this roast beef debris is in the crockpot instead of the oven.  I love my crock pot as much as I love my cast iron dutch oven and skillet. You may already cook your roast in a crock pot. My main purpose with this post is not only to give you a great crock pot roast recipe but to give you lots of different ideas to serve the Crock Pot Roast Beef.  

New Orleans Inspired My Cooking

Living in the New Orleans area and eating Roast Beef Debris on everything inspired me to make Roast Beef Po Boys, Fries, Burgers, and Stuffed Potatoes at home.  After cooking the Slow Cooker Roast Beef on low for eight hours in my slow cooker, I remove it from the slow cooker.  It will fall apart or pull apart at this point with just a fork.  I take a sharp knife and chop it up into small pieces.  Chopping the Slow Cooker Roast Beef up looks more like Roast Beef Debris from New Orleans.

Fix the Gravy

 Next, I prepare the gravy.  The secret to the gravy is adding the broth the roast was cooking in back into the gravy.  The broth is seasoned extremely well and makes a fantastic gravy.  New Orleans Roast Beef Debris has the roast bits, and pieces added back into the gravy. I like to add my gravy on top of my Slow Cooker Roast Beef.
