Why This Pastrami Reuben Recipe Works

The magic of a great Pastrami Reuben lies in the harmonious balance of its core components. This recipe excels by focusing on quality ingredients and precise techniques to maximize flavor and texture:

• Layered Flavor Profile: Each ingredient contributes a distinct flavor – the smoky, spiced pastrami; the tangy, fermented sauerkraut; the creamy, savory dressing; and the nutty, melted Swiss cheese. Together, they create a complex and incredibly satisfying taste.
• Perfect Texture Contrast: The crisp, buttery rye bread offers a delightful crunch, which perfectly contrasts with the tender pastrami, juicy sauerkraut, and soft, melted cheese. This textural variety keeps every bite interesting.
• Homemade or Deli-Quality: While we encourage using homemade pastrami for an unparalleled depth of flavor, this recipe is equally fantastic with high-quality, thinly sliced pastrami from your local deli, making it accessible to everyone.
• Easy to Assemble: Despite its gourmet appeal, this sandwich is surprisingly simple to put together, making it an ideal choice for a quick lunch or a satisfying dinner.

Ingredients for the Perfect Hot Pastrami Sandwich

Crafting an exceptional Hot Pastrami Sandwich starts with selecting the best ingredients. Here’s a detailed look at what you’ll need, why each component is crucial, and thoughtful substitution options to customize your reuben. For precise measurements, please refer to the comprehensive recipe card at the bottom of this post.

• Rye Bread: The foundation of any authentic reuben. My absolute preference is to source fresh, homemade marble rye from a local Jewish deli, if possible, for its unparalleled flavor and texture. Otherwise, quality Jewish rye bread from your grocery store is an excellent alternative. You can opt for dark rye for a bolder flavor, or any preferred variety of rye. While sourdough bread can work in a pinch for a different twist, traditional pastrami sandwiches truly shine with rye bread. Its subtle tang and sturdy crumb hold up beautifully to the rich fillings.
• Unsalted Butter: Essential for achieving that golden-brown, crispy crust on your bread. I specifically recommend unsalted butter to maintain control over the overall sodium content, as pastrami itself brings a significant salty element to the sandwich.
• Thousand Island Dressing: This creamy, zesty dressing is a hallmark of the classic reuben. It typically features a mayonnaise and ketchup base, often with chopped hard-boiled egg, sweet pickle relish, and finely minced onions or bell peppers, contributing a delightful balance of sweet, tangy, and savory notes.
  • Substitution: Russian Dressing is a fantastic alternative. While similar in its creamy base, traditional Russian dressing often includes horseradish, Worcestershire sauce, and chili sauce, giving it a spicier, more pungent kick compared to Thousand Island.
• Pastrami: The star of the show. For this recipe, you’ll need either luscious, leftover homemade pastrami (which we highly recommend!) or high-quality, thinly sliced pastrami from your deli counter. The thickness of your slices can vary; I find that thinly sliced pastrami is easier to pile high and ensures even heating. If you’re slicing it yourself at home, use your sharpest knife or an electric knife to achieve those desirable paper-thin cuts. The rich, spiced, and smoky flavor of pastrami is what defines this sandwich.
• Sauerkraut: This fermented, thinly sliced cabbage is non-negotiable for a classic Reuben sandwich. It introduces a vital tangy flavor and a satisfying crunchy texture that cuts through the richness of the pastrami and cheese. If you desire a more traditional “pastrami on rye” rather than a reuben, you can opt to omit the sauerkraut, but I personally find its bright acidity indispensable.
• Swiss Cheese: You’ll need thin slices of Swiss cheese, specifically chosen for its excellent melting properties and mild, nutty flavor. It creates that irresistible gooey layer that binds the sandwich together and adds a wonderful creamy dimension. Varieties like Emmental or Gruyere can also be used for a slightly stronger flavor profile.

Step-by-Step Instructions: Assembling Your Perfect Hot Pastrami Reuben

Creating this iconic deli sandwich at home is simpler than you might think. Follow these clear, detailed steps to achieve a perfectly grilled, flavorful Hot Pastrami Reuben. I’ve included helpful tips and detailed explanations to make the process enjoyable and foolproof. For the full, precise recipe instructions and ingredient quantities, please refer to the recipe card at the very end of this post.

1. Prepare the Sauerkraut: This is a critical first step to prevent your sandwich from becoming soggy. Place the sauerkraut into a fine mesh strainer. Using several sheets of paper towel, press down firmly on the sauerkraut to squeeze out as much excess liquid as possible. If you don’t have a mesh strainer, simply stack 3-4 paper towels, place the sauerkraut on top, and use another 2-3 paper towels to press from above. Set the well-drained sauerkraut aside.
2. Butter the Bread and Apply Dressing: Take each slice of rye bread and generously spread softened unsalted butter on one side. This buttered side will be grilled to a golden crisp. Flip the bread slices over, and on the unbuttered side of each slice, spread a tablespoon of Thousand Island dressing. The dressing acts as a flavor layer and helps adhere the other ingredients.
3. Assemble the Layers: On the side of each bread slice that has the Thousand Island dressing, place a slice of Swiss cheese. Now, take half of your bread slices (those topped with dressing and cheese) and pile a generous amount of sliced pastrami and drained sauerkraut on top. Then, carefully place the other half of the bread slices (also topped with dressing and cheese) butter-side-up over the pastrami and sauerkraut, forming your sandwiches.
4. Cook the Sandwiches: Heat a large skillet or griddle pan over medium heat on your stove. Once hot, carefully place the assembled sandwiches onto the skillet or griddle. Grill for 3-4 minutes per side, or until the rye bread is beautifully golden brown and crispy, and the Swiss cheese has completely melted and become wonderfully gooey. Use a spatula to gently flip the sandwiches.
5. Serve Immediately: Once perfectly grilled, remove the Hot Pastrami Reubens from the skillet. For ease of eating and a classic presentation, you can slice each sandwich in half diagonally. Serve them hot and enjoy every delicious bite!

Tips for Success

• Thin Slices are Key: The thinner your pastrami, the easier it is to pile high and the more tender it feels in the sandwich. Cold pastrami is much easier to slice thinly, so if using homemade, chill it completely before slicing.
• Don’t Skip Draining the Sauerkraut: Excess liquid will make your bread soggy, ruining the texture. Pressing out as much moisture as possible is crucial for a crisp sandwich.
• Butter Generously: A good layer of butter on the outside of your bread creates that desirable golden, crispy crust when grilled.
• Medium Heat is Your Friend: Cooking over medium heat allows the bread to toast evenly and the cheese to melt slowly without burning the outside.
• Warm Your Pastrami (Optional but Recommended): If your pastrami slices are particularly thick, consider quickly warming them in the skillet for 30-60 seconds per side before assembling the sandwich. Thin slices will heat through as the sandwich cooks.
• Piling High: For a truly authentic deli experience, don’t be shy with the pastrami! I recommend at least ¼ pound per sandwich, but for a “sky-high” NYC-style reuben, go for a generous ½ pound.

Variations to Try

While the classic Hot Pastrami Reuben is perfect as is, you can easily customize it to your taste:

• Cold Pastrami Sandwich: If you prefer a chilled sandwich, simply omit the cooking step and the butter. Assemble all ingredients and serve immediately.
• Traditional Pastrami on Rye: For a simpler, more focused flavor, swap the Thousand Island dressing for a spread of spicy brown mustard. You can keep the sauerkraut for its tang or leave it off for a purist “pastrami on rye.”
• Different Cheeses: Experiment with other melty cheeses like Provolone, Muenster, or even a sharp White Cheddar for a different flavor profile.
• Bread Alternatives: While rye is classic, sourdough or pumpernickel can offer interesting textural and flavor variations. For a gluten-free option, ensure you use a sturdy gluten-free bread, as all other ingredients in this recipe are typically gluten-free.
• Spice It Up: Add a dash of hot sauce to your Thousand Island dressing or a few pickled jalapeños for a spicy kick.
• No Sauerkraut? No Problem!: If sauerkraut isn’t your favorite, you can replace it with thinly sliced coleslaw for a similar crunch and tang, or even some caramelized onions for a sweeter note.

Storage and Reheating

Ideally, Pastrami Reuben sandwiches are best enjoyed immediately after preparation, when the bread is crisp and the cheese is wonderfully melted. However, if you find yourself with leftovers or wish to prep some components in advance, here’s how to handle it:

• Storing Leftovers: If you have a fully assembled and cooked sandwich, wrap it tightly in aluminum foil and store it in the refrigerator for up to 1-2 days. The bread will soften, but it will still be delicious.
• Reheating: The best way to reheat a pastrami reuben is in a skillet or on a griddle over medium-low heat. This allows the bread to crisp up again and the cheese to remelt gently. Heat for a few minutes per side until warmed through. Avoid the microwave, as it will make the bread soggy.
• Prepping Components: You can slice your pastrami and drain your sauerkraut a day in advance. Store them separately in airtight containers in the refrigerator. This will significantly cut down on assembly time when you’re ready to make your sandwiches.
