Why You’ll Love This Chopped Pastrami Sandwich Recipe

A great pastrami sandwich balances smoky meat, tangy sauce, and melted cheese. This version checks every box.

Making homemade pastrami from corned beef gives the meat incredible flavor and tenderness. Smoking the beef low and slow allows the seasoning to develop a beautiful bark while keeping the interior juicy.

Once the meat is thinly sliced and lightly chopped, it becomes the perfect filling for a hot sandwich. When the salty pastrami meets caramelized onions and a slice of Swiss cheese, the result is rich, savory, and incredibly satisfying.

The creamy island dressing adds sweetness and tang, while spicy brown mustard cuts through the richness for the perfect bite.

Ingredients You’ll Need for a Chopped Pastrami Sandwich

Homemade Pastrami

• 3 pounds uncooked corned beef brisket
• 3 tbsp beef rub
• 1 cup beef broth

Sandwich

• Brioche buns or hoagie roll
• 2 tbsp spicy brown mustard or stone ground mustard
• 2 slices Swiss cheese
• 1 large yellow onion

Thousand Island Dressing

• ½ cup mayonnaise
• 2 tbsp ketchup
• 2 tbsp sweet pickle relish
• ½ tsp black pepper

Combine the dressing ingredients in a small bowl and mix thoroughly until smooth. This creamy island dressing pairs perfectly with the smoky pastrami.

How to Make a Chopped Pastrami Sandwich

Step 1: Prepare the Corned Beef

Start by removing the seasoned corned beef from the packaging. Place it in cold water and refrigerate it for 2–6 hours.

Soaking helps draw out some of the excess salt, preventing the finished meat from becoming overly salty.

After soaking, remove the beef and pat it dry using a paper towel. Lightly coat the outside with your favorite beef rub.

Step 2: Smoke the Homemade Pastrami

Preheat your smoker to 250°F.

Place the seasoned corned beef directly onto the smoker grates. Smoke it for 4–6 hours, spritzing it with beef broth every hour to keep the surface moist and help develop the bark.

Once the exterior bark is set, remove the beef from the smoker and place it in aluminum foil with a splash of beef broth or beef tallow. Wrap the foil tightly and return it to the smoker.

Continue cooking until the meat reaches an internal temperature of 205°F.

At this point, you’ll have beautifully tender homemade pastrami.

Step 3: Rest and Slice the Pastrami

Remove the wrapped beef from the smoker and place it in a cooler to rest for 1–3 hours. Resting helps the juices redistribute and keeps the meat moist.

Once rested, slice the pastrami against the grain into thin slices.

For this chopped pastrami sandwich recipe, roughly chop the slices so they pile nicely onto the sandwich.

If you’re short on time, buying pastrami from the deli counter is a good substitute, though smoking your own provides unbeatable flavor.

Step 4: Caramelize the Onions

Thinly slice the yellow onion.

Heat a skillet over medium-high heat with a little oil or butter, then add the onions. Cook them slowly for about 20 minutes, stirring occasionally, until they turn soft and golden brown.

Caramelized onions bring sweetness that balances the richness of the pastrami.

Step 5: Build the Chopped Pastrami Sandwich

Toast the inside of your brioche buns until lightly golden brown. You can also use a hoagie roll, rye bread, or marble rye if you want something closer to a traditional pastrami sandwich.

Spread a layer of spicy brown mustard on the toasted bun.

Next, place pastrami onto the bun, followed by caramelized onions and a slice of Swiss cheese. The nutty Swiss cheese melts beautifully over the hot meat, creating that irresistible melty cheese layer.

Drizzle some of the homemade island dressing over the top before adding the bun lid.

Step 6: Serve and Enjoy

Serve your chopped pastrami sandwich hot with a side of potato chips or pickles.

Each bite delivers smoky meat, sweet onions, tangy dressing, and creamy melted cheese. The balance of textures and flavors makes this one of the most satisfying sandwiches you can make at home.

Tips for the Best Chopped Pastrami Sandwich

1. Slice the meat thin.
Thin slices of pastrami make the sandwich more tender and easier to eat.

2. Don’t skip the rest time.
Resting the meat helps retain juices and keeps it moist.

3. Toast the bread.
Toasting prevents the bun from getting soggy and adds extra texture.

4. Customize your bread.
While brioche works great, a hoagie roll, rye bread, or marble rye also creates a fantastic sandwich.
