Classic New York Style Pastrami Reuben Melt Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are measured and ready, as the griddling process happens quickly. Drain the sauerkraut thoroughly in a fine-mesh sieve, pressing down gently to remove as much liquid as possible to prevent a soggy sandwich.

Have the Swiss cheese sliced and ready to layer. Prepare the Russian dressing in a small bowl so it is ready for immediate application. Position the cast-iron griddle on the stove, preheating it to 360°F to ensure it is ready when the assembly begins.

Instructions

Dressing and Prep

1. 1Prepare dressing and pastrami
   In a small bowl, whisk together the mayonnaise, chili sauce, and horseradish until fully combined. Set aside to allow flavors to meld. Steam the thick-cut navel pastrami until hot and fragrant.
   Look for The pastrami should be steaming hot and the dressing smooth and consistent.
   Tip Whisking the dressing ahead of time allows the horseradish to fully infuse the sauce.

The Russian dressing should be smooth and well-incorporated, with a balanced tang from the horseradish and chili sauce. The pastrami should be heated until it releases its signature peppery aroma. Ensure that the sauerkraut is as dry as possible, as this is vital for maintaining the crispness of the toasted bread during the final cooking phase. Everything should be organized near the stovetop for a seamless assembly process.

Assembly and Griddle

2. 2Assemble and griddle
   Butter one side of each bread slice. Place one slice butter-side down on a 360°F griddle. Layer with one slice of Swiss cheese, the hot pastrami, drained sauerkraut, dressing, the second slice of cheese, and top with the remaining bread, butter-side up. Press firmly with a cast-iron weight.
   Look for The bread should be golden brown and the cheese completely melted.
   Tip Using a heavy press ensures even contact and a crisp, uniform crust on the bread.

The sandwich should be assembled with the cheese layers touching the bread to act as an adhesive. The griddle should be at a steady temperature to ensure the butter browns evenly without smoking. Placing the weight on the sandwich is essential for creating the characteristic flat, compressed profile of a deli Reuben. Listen for a consistent, gentle sizzle, which indicates the bread is frying correctly in the butter rather than steaming.

Final Sear and Serve

3. 3Final cook and serve
   Cook for 3 minutes per side under the weight until the rye is toasted to a deep golden brown and the cheese is oozing. Remove from heat, slice the sandwich in half, and serve immediately while the fillings are warm and the cheese remains melted.
   Look for The crust must be crispy and the cheese fully melted through the pastrami layers.
   Tip Slice with a serrated knife to maintain the structure of the sandwich without crushing the layers.

At this stage, the sandwich should look structurally firm and perfectly browned. The cheese should be visibly bubbling at the edges of the bread. When sliced, the internal layers should stay stacked, showing a distinct contrast between the dark rye, the pink pastrami, and the melted Swiss.

The sandwich is ready to serve immediately, ensuring the bread remains crisp and the filling retains its warm, comforting temperature for the best eating experience.

Common mistakes

A common mistake is failing to drain the sauerkraut adequately, which introduces excess moisture that prevents the bread from crisping properly. Another error is using a heat that is too high, which can burn the exterior of the rye bread before the cheese has had a chance to melt through the layers.

Ensure the griddle is maintained at a consistent 360°F. Additionally, neglecting to press the sandwich firmly can lead to uneven cooking and a lack of structural integrity when slicing.

How to tell it’s done

The sandwich is done when the rye bread is toasted to a deep, uniform golden brown color on both sides. The Swiss cheese should be visibly melted and beginning to drip from the sides of the sandwich. The internal layers should be steaming hot.

Use a firm touch to ensure the cheese has softened sufficiently, which indicates that the heat has permeated the entire sandwich. The total cooking time should result in a crisp exterior and a warm, cohesive center without any cold spots.
