A pastrami Reuben stacked with sauerkraut, Swiss, and Russian dressing on griddled rye is a high protein deli masterpiece. This bold, tangy sandwich is a family-favorite twist on the classic.
Preheat a skillet or griddle over medium heat—ensure consistent moderate heat for even browning.
Spread 1/2 tbsp unsalted butter on one side of each rye bread slice.
Lay 4 slices, butter-side down, and spread 1 tbsp Russian dressing per slice; layer each with 4 oz pastrami, 2 slices Swiss cheese, and 1/4 cup sauerkraut.
Top each sandwich with the remaining bread slices, butter-side up, pressing gently.
Cook sandwiches 5-6 minutes per side, pressing lightly and turning once; grill until golden brown and cheese has fully melted. Rest for 1 minute before serving to let the interior settle.
