Piled-high corned beef, tangy sauerkraut, melty Swiss cheese, and creamy Russian dressing pressed between two slices of buttery toasted rye bread - the Reuben is the St. Patrick's Day sandwich that deserves more hype. Every bite drips with savory, tangy, cheesy perfection.
Preheat a large skillet or griddle over medium heat—this steady, moderate heat ensures the bread crisps evenly without burning before the cheese melts.
Lay out all 8 slices of rye bread. Spread softened butter on one side of each slice; this step delivers a deeply golden, flavorful crust.
Flip half the bread slices and generously spread Russian dressing on the unbuttered sides. Layer each with 2 slices of Swiss cheese, then divide the corned beef evenly among the sandwiches, piling it high for that signature hearty Reuben bite.
Use clean hands to gently squeeze and drain sauerkraut—removing excess moisture keeps the bread from getting soggy. Scatter a generous layer over the corned beef, season lightly with black pepper, then cap each sandwich with another slice of bread, buttered side out.
Place the sandwiches onto the heated skillet, pressing gently with a spatula. Cook 4–5 minutes per side, pressing occasionally, until the bread is crisp and deep golden and the cheese inside is fully melted. The slow toasting allows the interior flavors to meld and each layer to heat through.
Transfer to a cutting board and let rest 2 minutes for melty cohesion. Slice in half and serve hot, with extra Russian dressing on the side if desired.
