Ingredients You’ll Need

Each ingredient plays a vital role in crafting this sandwich’s signature taste. From the tender homemade pastrami to the zesty cabbage slaw and creamy special sauce, picking fresh quality ingredients really pays off — especially with classic rye bread and Swiss cheese for that melt factor.

• Homemade pastrami: The star of the sandwich; tender, flavorful, and juicy. Making it yourself guarantees freshness and a melt-in-your-mouth texture.
• Light rye bread: Provides a sturdy, flavorful base with just enough tang; light rye won’t overpower but holds everything together.
• Swiss cheese: Melts beautifully and adds nuttiness without competing with the pastrami’s spiced flavor.
• Butter: Used for spreading on bread to get that gloriously golden, crispy crust during toasting.
• Grapeseed oil: Great for lightly sautéing onions without overpowering the sandwich’s taste.
• Onion (thinly sliced and minced): Adds sharp, sweet notes both in the sandwich and sauce for depth.
• White cabbage (thinly shredded): Creates a zesty, crunchy slaw that balances richness with acidity.
• Cider vinegar, water, salt, sugar: These create a tangy brine for pickling the cabbage just right, not soggy but wonderfully crisp.
• Caraway seeds (optional): Adds a subtle aromatic earthiness—try it if you like a traditional Eastern European twist.
• Dill pickle/gherkin (finely minced): Bursts of tangy crunch in the sauce, brightening every bite.
• Mayonnaise and sour cream: Creamy base for the sandwich’s signature sauce, balancing heat and acidity.
• Sriracha, ketchup or chili sauce: Injects a satisfying spicy kick; adjust amount to your preferred heat level.
• Horseradish: The essential spicy tang that wakes up the palate—use fresh from jar for best flavor.
• Worcestershire sauce and sweet paprika: Layers complexity and smoky sweetness in the sauce.

Variations

I love how versatile this Homemade Reuben Sandwich with Pastrami Recipe is. Feel free to customize it to suit your taste buds or dietary preferences—tweaking the spice levels or swapping ingredients can make it your own signature sandwich.

• Switch the cheese: I’ve tried swapping Swiss for Gruyère or even aged cheddar; both add their unique twist and melt beautifully.
• Go gluten-free: Use gluten-free rye-style bread to keep that classic texture without gluten worries.
• Customize your heat: Adjust the sriracha or horseradish amount to tame or crank the spiciness—my family goes crazy for the spicy version, but it’s easy to dial down.
• Make it vegetarian: Swap pastrami for grilled tempeh or smoked mushrooms with the same sauce and slaw for a delicious meat-free alternative.

How to Make Homemade Reuben Sandwich with Pastrami Recipe

Step 1: Prepare the Tangy Cabbage Slaw

Start by making the tangy slaw—this gives the sandwich a refreshing crunch and balances the richness of the pastrami. Combine thinly shredded white cabbage with cider vinegar, water, salt, sugar, and caraway seeds. Let it sit while you move on to the rest—it softens just right without losing that snap. Trust me, the sweetness and acidity in this slaw are what make this sandwich sing!

Step 2: Whip Up the Special Sauce

Mix mayonnaise, sour cream, sriracha (or your chosen hot sauce), horseradish, Worcestershire sauce, minced onion, minced dill pickle, and a dash of paprika. This sauce is the creamy, spicy heart of your sandwich. When I first made this, I was amazed at how it took the flavor profile to a whole new level simply by adding punchy horseradish and the tang from the pickles.

Step 3: Sauté the Onions and Warm the Pastrami

Heat grapeseed oil in a pan over medium heat and gently sauté the thinly sliced onions until soft and golden. Then, add the homemade pastrami slices just to warm them through. This step unlocks the best aromas and texture—warm, tender pastrami makes all the difference. If you skip warming the meat, you might miss out on that melt-in-your-mouth magic.

Step 4: Assemble and Toast Your Sandwich

Butter one side of each rye bread slice generously. On the unbuttered side, layer Swiss cheese, warm pastrami with onions, slaw, and a generous smear of the special sauce. Top with another slice of bread, butter side out. Toast on a skillet over medium heat, pressing gently, until the bread is golden brown and cheese has melted—about 3-4 minutes per side. Flip carefully! The toasting step is where everything comes together in melty, crunchy harmony.

How to Serve Homemade Reuben Sandwich with Pastrami Recipe

Garnishes

I love adding a few crunchy dill pickle slices on the side as a classic garnish; they brighten each bite and cut through the richness perfectly. If you want to get fancy, a sprinkle of fresh parsley on top adds color and freshness.

Side Dishes

My go-to sides are kettle-cooked potato chips or classic dill pickles. When I’m feeling cozy, homemade baked fries or a simple cucumber salad works beautifully—something crisp and light to balance the sandwich’s hearty flavor.

Creative Ways to Present

For special occasions, I like cutting the sandwich into finger-friendly halves or quarters and serving on a rustic wooden board with small dipping bowls of extra sauce and pickles. It’s great for sharing, looks inviting, and always starts a conversation!

Make Ahead and Storage

Storing Leftovers

If you have leftovers (and I hope you do!), keep the sandwiches wrapped tightly in plastic wrap or foil in the fridge for up to 2 days. I usually separate the components—pastrami and slaw stay fresher without the bread getting soggy.

Freezing

Freezing a fully assembled Reuben doesn’t work well—the bread sogginess is inevitable. Instead, freeze the homemade pastrami separately, slice-by-slice wrapped with parchment paper, so you can thaw portions as needed.

Reheating

Reheat leftover pastrami gently in a skillet or microwave. When reheating the sandwich, toast it again briefly to crisp the bread and melt the cheese. Avoid microwaving the whole sandwich cold—it often leads to a soggy mess.
