Ingredients Needed

For the Sandwich Base
- 4 Tbsp unsalted butter, softened – makes the bread perfectly golden and crisp

- 4 Tbsp yellow mustard (plus extra for serving) – adds the iconic tangy punch
How to Make Pastrami Sandwich
Step 1 — Prepare the Bread and Layering
Spread a thin layer of softened butter on one side of each slice of rye bread. Flip 4 slices over so the buttered side faces down. Spread the unbuttered side of those slices with mustard, making sure to reach the edges for even flavor. Pile the sliced pastrami generously on top—it should be full, not flat. Place the remaining bread slices on top, buttered side facing outward.
Tip: Press gently to help the sandwich hold together while cooking.

Step 2 — Toast the Sandwiches
Heat a medium skillet over medium heat. Once warm, place the sandwiches in the pan without overcrowding. Toast for about 3 minutes per side, or until the bread is deeply golden and you start to smell the pastrami warming and the butter sizzling.
Visual cue: The bread should feel crisp when gently tapped with a spatula.
Step 3 — Serve Warm
Transfer the hot sandwiches to a platter and slice in half if desired. Serve immediately with extra mustard on the side for dipping.
Tip: Let the sandwich sit for 1 minute before cutting—this keeps the layers intact.

Serving and Storage Tips
- Serve with crunchy pickles, coleslaw, potato chips, or a classic deli salad.
- Add melted Swiss or provolone for a cheesy upgrade.
- Store leftovers (already assembled but not toasted) wrapped tightly in plastic for up to 1 day.
- Reheat in a skillet or panini press for crispness—avoid the microwave, which softens the bread.
Helpful Notes
- Warm the pastrami briefly in a skillet before assembling if you want extra steam and tenderness.
- Swap yellow mustard for Dijon, spicy mustard, or even Russian dressing.
- For extra crunch, add sauerkraut or sliced pickles inside the sandwich.
- Rye bread is classic, but sourdough or multigrain also work beautifully.

Frequently Asked Questions (FAQ)
Can I use a different type of bread?
Absolutely! Sourdough, marble rye, whole wheat, or even a baguette all work well as long as they toast nicely.
Can I make this sandwich gluten-free?
Yes—simply use your favorite gluten-free bread and follow the same steps.
Can I add cheese to this pastrami sandwich?
Definitely. Swiss, provolone, or cheddar melt beautifully and pair perfectly with pastrami.
Can I prepare the sandwiches ahead of time?
You can assemble them a few hours in advance and refrigerate. Toast just before serving for best texture.
Is pastrami sandwich freezer-friendly?
It’s not ideal. Freezing affects the bread and deli meat texture, so fresh is best.
Why is my bread getting soggy?
Be sure the mustard layer is thin and the skillet is hot enough. A warm, crisp sear prevents moisture from soaking into the bread.
