Servings 8 servings


  • 3.5 to 4 pounds corned beef brisket rinsed and drained
  • Seasoning packet from corned beef brisket package
  • 1 medium onion quartered
  • Water (about 3 cups)
  • 16 large slices rye or hearty white bread
  • softened butter
  • 1/2 cup Thousand Island or Russian Salad Dressing
  • 2 cups sauerkraut
  • 2 cups shredded Swiss cheese


  • Place the corned beef on the trivet inside a 6-quart Instant Pot and add the seasonings and onion.
  • Pour in just enough water to come half way up the brisket-that's all that's necessary and probably could get by with less.
  • Put the lid on the Instant Pot and seal the valve.
  • Set the Instant Pot to manual (high) pressure for 1.5 hours. For a 4 pound brisket, cook 1 hour 40 minutes.
  • Allow the pot to release naturally for 15 minutes and quick release. Remove the brisket to a cutting board and let cool to the touch.
  • Cut the brisket across the grain into slices or shred it.

Reuben Sandwiches:

  • Spread the salad dressing on both sides of the bread slices. Add sliced corned beef, sauerkraut, and cheese.
  • Heat a nonstick skillet or griddle until hot
  • Spread softened butter on the top piece of bread and place that side down in the pan.
  • Now, spread butter on the other side of the sandwich bread which will be on the top.
  • Cook 2 minutes or until the bread is lightly browned. Turn gently with a spatula and cook 1 to 2 minutes on the other side until lightly browned and the cheese is melted.
