Cajun Roast Beef

Cajun Roast Beef


"Not being from the Gulf Coast but living here now, I love the Cajun Roast Beef you can get in the delis right alongside the regular. Distinctively garlicky, I wanted to try roasting it in my own kitchen but found few recipes. Here's my version. It's not spicy, but it has the garlic and thyme that meld to make the savory, regional flavor. We like to serve the beef on toasted rolls with garlic mayonnaise."

  1. Stir the garlic, horseradish, hot pepper sauce, thyme, salt, pepper, Cajun seasoning, olive oil, and malt vinegar together in a bowl until thoroughly blended.
  2. Pierce the beef roast all over with a meat fork. Place the roast in a large, resealable plastic bag. Spoon in the marinade and turn the roast so it's well coated. Refrigerate overnight, turning occasionally if desired.
  3. When ready to cook, place the roast in a slow cooker along with any remaining marinade. Do not add water. Roast on Low for 8 to 10 hours, or until desired doneness. For medium-rare, a meat thermometer should read 135 degrees F (57 degrees C). Remove from the slow cooker to a serving plate, and allow to rest 15 minutes before slicing across the grain.

Ok Well this recipe was WAY off, but it's really good when done correctly. If you leave this in for 8-10 hours it's going to be a brick! I had a larger roast and it was over done at like 4 hours when I started to temp it. Start to temp this after two or three hours and it should come out ok. If you do over cook it, just slice it up and put it in a pot with gravy and it will come out more moist, and will be like pot roast. Then Add the original drippings to the gravy depending on how spicy you would like it. The flavor of this was REALLY great though! I highly recomned this, just remember to temp it earlier than the recipe says.


The flavor is awesome tasty!! I cooked my 3lb roast for 5 hours and it was a little dry, but putting the drippings on it made it wonderful! Next time I'm going to try doubling the ingredients except the roast and see if that helps.


I gotta tell you that I made this and even without the Horseradish it was very good. I did add a little beef broth because I was afraid that it would be too dry and I wasn't going to be home to check on it. We made sandwiches out of it and it was gone fast. Next time I'm going to try it with the Horse radish and buy a bigger cut of roast.
