The first time I ever had a po' boy was in NOLA. This recipe is just as good if you can't get there. It is so tasty and yummy. I can't believe how good it is. I made it for my family, and they loved it. They couldn't get enough. Make sure you have enough napkins around! This recipe is perfect to make in the slow cooker for those days you're just too busy or it's too hot outside. I hope you enjoy it!

Blue Ribbon Recipe

Traditional Louisiana po' boy sandwiches vary by what area you're visiting, and this twist on a roast beef po' boy sandwich is delicious. Making a darker roux for the debris gravy is traditional to Louisiana cooking. For a slow cooker dish, this is made with love and takes a little time. The roast beef is cooked to tender perfection, shredded, and then coated in the dark, rich gravy. Use crusty French bread or a hoagie bun to hold the flavorful shredded beef. Adding mayonnaise, lettuce, and pickles makes for a delicious sandwich. You can even use a jalapeno mayo for a little kick.

How To Make slow cooker roast beef po' boys with debris gravy

  • Salt, pepper, garlic powder, paprika, and oregano in a small bowl.
    1
    In a small bowl combine Kosher salt, pepper, garlic powder, paprika, and oregano.
  • Searing meat, covered in seasonings, in a skillet.
    2
    After trimming fat off the meat (which we will use later use), rub all sides of the meat with the dry rub ingredients. Allow to sit on meat for about 15 minutes or until desired. In a heavy bottom skillet (or insert of slow cooker) heat olive oil. Place roast in pan and sear all sides until a nice dark crust is formed (about 3-5 minutes on each side). When finished remove from heat to a plate and cover with foil.
  • Pieces of fat in a slow cooker.
    3
    In the bottom of the slow cooker insert, place trimmed fat (fat side down).
  • Pureed onions, garlic, parsley, and mushrooms in a cast iron skillet.
    4
    In a food processor combine onions, garlic cloves, parsley, and mushrooms. Puree until smooth. Add mushroom-onion mixture to pan (or slow cooker insert) and cook for about 7-10 minutes until the liquid has evaporated. Place the mixture in the slow cooker and then place the roast on top of it.
  • Ale, water, demi-glace, and bouillon in the skillet.
    5
    In the pan used to cook these ingredients, deglaze with 8 oz amber ale and 8 oz water. Add demi-glaze and bouillon cubes. Stir to combine.

    When the meat has finished cooking, remove the meat to a plate and cover it with foil.
  • Skimmed liquid, water, and red wine vinegar in a measuring cup.
    8
    Pour the liquid from the Crock Pot into a measuring cup and skim the fat off the top. Discard any remaining fat pieces. Mix in the red wine vinegar and water.
  • Melted butter and flour to create a roux.
    9
    In a saucepan, melt butter. When it begins to bubble add flour. Stir to create a roux. It should be between a blonde and a brown roux.
  • Whisking liquid into the roux.
