  • 1 package (2 pounds) refrigerated sauerkraut
  • 1 package (2 to 3 pounds) corned beef brisket
  • 1 cup Thousand Island dressing
  • 16 slices pumpernickel rye bread, toasted
  • 8 slices (1 ounce each) Swiss cheese


  • 1
    Place sauerkraut in 3- to 4-quart slow cooker. Place beef brisket on sauerkraut. (If brisket includes packet of spices, sprinkle spices over brisket.)
  • 2
    Cover and cook on Low heat setting 9 to 11 hours.
  • 3
    Remove beef from cooker; place on cutting board. Cut beef into slices. To serve, spread 1 tablespoon dressing on each toast slice. Using slotted spoon to remove sauerkraut from cooker, top 8 slices toast with 1/2 cup sauerkraut each. Top sauerkraut with beef slices and cheese slice. Top with remaining toast. Note: This recipe was tested in slow cookers with heating elements in the side and bottom of the cooker, not in cookers that stand only on a heated base. For slow cookers with just a heated base, follow the manufacturer’s directions for layering ingredients and choosing a temperature.

Tips from the Betty Crocker Kitchens

  • tip 1
    These Slow-Cooker Reuben Sandwiches cry out for a good garlic dill pickle, purchased German potato salad or crunchy potato chips and a side of deli slaw.
  • tip 2
    To make this a portable potluck sandwich, stir the sliced beef into the sauerkraut. Place the dressing in a squeeze bottle (like for ketchup), and set out a basket of rye buns and smaller slices of Swiss cheese to make it easy for guests to make their own sandwiches.
  • tip 3
    Need a hearty party snack? Build the sandwiches on slices of party rye for a three-bite treat.
