- 16 ounces sauerkraut, drained but not rinsed
- 1 cup Thousand Island dressing or Russian dressing

- Tongs
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Spray the inside of your slow cooker with nonstick cooking spray or lightly grease it with oil or butter. This helps prevent sticking and makes cleanup easier later.
Step 2: Add the Sauerkraut Base
Spread the drained sauerkraut evenly across the bottom of the slow cooker. This acts as a flavorful base and keeps the corned beef elevated while it cooks.
Make sure you drain the sauerkraut well, but do not rinse it. The natural tangy juices are essential for authentic Reuben flavor.
Step 3: Season and Add the Corned Beef
Take the corned beef brisket and pat it dry with paper towels. Sprinkle the included seasoning packet evenly over the meat.
Place the seasoned brisket directly on top of the sauerkraut layer.
Step 4: Add the Dressing
Pour the Thousand Island or Russian dressing evenly over the top of the corned beef. Allow some of it to drip down the sides for maximum flavor infusion.
This dressing creates a rich, creamy sauce as the beef cooks.
Step 5: Slow Cook
Cover the slow cooker with the lid.
Cook on:
- Low: 8 to 9 hours (recommended for the most tender beef)
or - High: 4 to 5 hours
The corned beef is ready when it easily falls apart with a fork.
Step 6: Shred the Beef
Carefully remove the corned beef from the slow cooker and place it on a cutting board or large plate.
Using two forks, shred the meat into bite-sized pieces.
Remove any excess fat if desired.
Step 7: Return Beef to Slow Cooker
Place the shredded beef back into the slow cooker and mix it with the sauerkraut and juices.
This helps every bite absorb even more flavor.
Step 8: Add the Swiss Cheese
Lay slices of Swiss cheese over the top of the shredded beef mixture.
Cover again and cook for an additional 10 to 15 minutes until the cheese melts beautifully.
