Instant Pot Corned Beef Reuben Sandwich is an easy pressure cooker recipe with braised corned beef brisket. These sandwiches are great to enjoy as leftovers to the St. Patrick's Day holiday or for a quick weeknight dinner. This sandwich is loaded with sauerkraut, thousand island dressing on toasted rye bread.
Release the steam. Open the pot and remove the beef. Set aside to cool.
Using two knives, shred the beef.
Toast the rye bread.
Add the Swiss cheese on top of one of the bread slices while the toasted bread is still hot so that it melts. You can also add the bread and cheese to the microwave for 15-20 seconds if you prefer bubbling cheese.
Next, add the shredded corned beef. Then top with sauerkraut.
Spread the Thousand Island dressing on the other slice of bread. Top the sandwich.
I typically make reuben sandwiches using the leftover corned beef from my corned beef and cabbage dinner. This recipe has been prepared with leftovers in mind.
