Slow Cooker Beef Debris Po Boy

‘Debris’ refers to beef that is cooked and then cut into shreds. In this case, we cut the beef first then cook it until it completely falls apart. The sauce is absolutely incredible. You’ll want to just take a spoonful of it and eat it right out of the slow cooker.

The aroma of the beef cooking in the delicious sauce will drive you crazy all day long. You will find yourself doing like I did, trying to rush the clock forward to dinnertime. Fortunately this recipe for a slow cooker beef debris po boy makes a big batch so you’ll have plenty of it on hand to enjoy again and again.

I love sandwiches topped with tender slow-cooked beef. Try my Italian slow cooker beefspicy ItalianFrench dip and New Orleans roast beef sandwiches too.

  1. I’m confused as to what happens to the other 3 cups of beef broth, The recipe says 4 cups of beef broth, divided. Then step 9 is the only mention of the broth when 1 cup is slowly mixed in.

    1. Hi, and sorry for the confusion. I see that you’re absolutely right about the broth. I went back and tried to locate my notes on when I made this recipe, but could not. But I did research other beef debris recipes, and for the size chuck I used adding 4 cups at once seems quite appropriate. I’d rather lean towards it being wetter than too dry. You can always squeeze out some of the moisture before piling it high on the bread. You can also use any extra juice for dipping the sandwiches!
