Adapted from a recipe by Sondra Morrow at Note this calls for a fresh beef brisket, NOT a "corned beef brisket." Additional note: I just made this for the first time; while it's very TASTY, it's not the TENDEREST brisket I've ever had, even though I sliced it very thin. I tossed a dozen baby Red Bliss potatoes in with the meat; they came out really good!

Ingredients Nutrition


  1. Place the brisket in a slow cooker. In a bowl, combine the ketchup, onion, vinegar, 1 tbsp horseradish, mustard, sugar and pepper. Pour over brisket. Cover and cook on low for 6 hours or until tender.
  2. Remove the beef; set aside. Pour the sauce into a saucepan and add remaining 1 tbsp horseradish; cook, uncovered, over low heat for 13-15 minutes or until reduced and thickened, stirring occasionally. Slice the meat across the grain; serve with sauce.
