Step 1

Gather the ingredients before you start.

Step 2

Heat the Blackstone griddle.  For a Blackstone griddle gas grill, preheat on medium.  If using an electric Blackstone, preheat the flat top griddle to 400°F.

Step 3

While the Blackstone griddle is heating up, lightly butter one side of each piece of the rye bread. Place two slices of Swiss cheese on top of one side of the non-butter rye bread slice. When the flat top griddle is hot, place both slices of the bread on the Blackstone so the buttered side is down.

Step 4

In another spot on the griddle, spread out the sliced pieces of corned beef.

Step 5

On the piece of rye bread without the Swiss cheese, top with the sauerkraut that has been rinsed and drained, so it is not dripping.  The last thing you want is soggy bread.

Step 6

Toss the sliced corned beef around on the hot griddle to evenly cook and heat up.

Step 7

Assemble the Blackstone Reuben sandwich by placing the warmed corned beef slices on top of the sauerkraut piece of bread and flip the sandwich on top of the other half.  Griddle grilling the corned beef Rueben sandwich will take about 3 to 5 minutes. You want a golden-brown sandwich. Serve the Corned Beef Rueben sandwiches warm with Thousand Island dressing and your favorite sides.
