🧀 Ingredient Notes
Thick-Cut Rye Bread
Thick-cut seeded rye or caraway rye bread gives this pastrami Swiss rye sandwich its classic deli flavor. A sturdy rye bread also holds up better to the warm pastrami, melted Swiss cheese, dill mayo, and sauerkraut.
Pastrami
Thinly sliced deli pastrami works best because it folds easily and creates a tender, stacked sandwich. Warm it just until hot with lightly caramelized edges for the best smoky, savory flavor.
Swiss Cheese
Swiss cheese adds a nutty, creamy flavor that melts beautifully with the pastrami. It also helps create a light barrier between the bread and fillings so the rye stays crisp.
Sauerkraut
Use refrigerated deli-style sauerkraut when possible for a brighter, tangier flavor. Drain and squeeze it very well so the sandwich stays crisp instead of soggy.
Lettuce
Shredded iceberg lettuce adds cool crunch and freshness. Add it after toasting the sandwich so it stays crisp and does not wilt.
Dill Mayo
The homemade dill mayo adds creamy, herby flavor that balances the smoky pastrami and tangy sauerkraut. Fresh dill gives the best flavor, but dried dill can be used in a pinch.
🥪 How to Make Pastrami Swiss Rye Sandwich with Dill Mayo
Step 1: Make the Dill Mayo
In a small bowl, stir together the mayonnaise, fresh dill, Dijon mustard, lemon juice, garlic, black pepper, and salt until smooth and creamy. Refrigerate until ready to use.
Step 2: Prepare the Sauerkraut
Drain the sauerkraut very well and gently squeeze out excess moisture using paper towels. Warm it in a skillet over low heat for about 30 seconds until heated through but not browned.
Step 3: Warm the Pastrami
Heat a skillet or griddle over medium heat. Add the pastrami and warm for 1–2 minutes until hot with lightly caramelized edges while still staying tender.
Step 4: Toast the Bread Interior
Place the rye bread slices onto the dry skillet for about 20–30 seconds to lightly toast the inside surfaces. This helps the bread stay crisp after the sandwich is assembled.
Step 5: Assemble the Sandwiches
Spread a thin layer of dill mayo onto the toasted interior sides of the rye bread. If desired, spread a thin layer of spicy brown mustard onto one slice.
Layer Swiss cheese, folded warm pastrami, warm sauerkraut, and the remaining Swiss cheese onto the bread before topping with the remaining bread slices.
Step 6: Toast the Sandwiches
Lightly butter the exterior sides of the bread. Add butter to the skillet over medium-low heat and cook the sandwiches for 3–5 minutes per side until the bread is deeply golden brown and crisp and the Swiss cheese is fully melted.
Step 7: Add Lettuce and Serve
Open the sandwiches carefully and add shredded iceberg lettuce immediately before serving. Let the sandwiches rest for 1 minute before slicing diagonally and serving hot.
🥪 Pro Tips for the Best Pastrami Swiss Rye Sandwich
Use Thick Rye Bread
Thick-cut seeded rye bread gives this pastrami Swiss rye sandwich the best deli-style flavor and helps hold the warm pastrami, Swiss cheese, sauerkraut, lettuce, and dill mayo without falling apart.
Drain the Sauerkraut Well
Sauerkraut adds the perfect tangy bite, but too much moisture can soften the toasted rye bread. Pat it dry with paper towels before warming it for the best texture.
Warm the Pastrami First
Heating the pastrami before assembling the sandwich makes it more tender, flavorful, and deli-style. Warm it just until hot with lightly caramelized edges.
Add Lettuce After Toasting
For the best crunch, add the shredded iceberg lettuce after the sandwich is toasted. This keeps the lettuce fresh, crisp, and cool against the warm filling.
Toast Over Medium-Low Heat
Medium-low heat allows the Swiss cheese to melt fully while the rye bread turns golden and crisp without burning.
🥪 Pastrami Swiss Rye Sandwich Variations
Classic Reuben Style
Turn this pastrami Swiss rye sandwich into a classic Reuben by replacing the dill mayo with creamy Thousand Island dressing and leaving out the lettuce for a more traditional deli-style sandwich.
Spicy Pastrami Sandwich
Add sliced pickled jalapeños, spicy brown mustard, or crushed red pepper flakes for extra heat and bold flavor that pairs perfectly with smoky pastrami and Swiss cheese.
Turkey Pastrami Version
Swap the traditional pastrami for turkey pastrami for a lighter sandwich with the same delicious deli-inspired flavor and texture.
Extra Cheesy Rye Melt
Add extra Swiss cheese or a slice of provolone for an ultra melty hot sandwich with even more rich, creamy flavor.
Loaded Deli Sandwich
Add sliced tomatoes, red onion, dill pickles, or coleslaw for an even bigger deli-style sandwich loaded with fresh texture and flavor.
🥪 Storage and Make Ahead Tips
How to Store Leftovers
This pastrami Swiss rye sandwich is best enjoyed fresh while the rye bread is hot and crispy, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days.
Keep the Lettuce Separate
For the best texture, store the shredded lettuce separately and add it after reheating so it stays crisp and fresh instead of becoming wilted.
Reheat for the Best Texture
Reheat the sandwich in a skillet over medium-low heat or in an air fryer until the bread becomes crispy again and the Swiss cheese is melted. Avoid microwaving if possible because it can make the rye bread soft.
Make the Dill Mayo Ahead
The homemade dill mayo can be prepared up to 3 days ahead and stored in the refrigerator in an airtight container. The flavor becomes even better as the dill and garlic blend together.
Prep Ingredients in Advance
You can drain the sauerkraut, shred the lettuce, and portion the pastrami ahead of time to make assembling the sandwiches quick and easy when ready to cook.
