Katz's Deli Pastrami Sandwich: The Secret Cheese Revealed

Katz's Delicatessen, a legendary New York City institution, is renowned for its towering pastrami sandwiches, a staple of Jewish-American cuisine. While the focus is often on the tender, peppery pastrami itself, the cheese choice plays a subtle yet crucial role in elevating the sandwich. Traditionally, Katz's pastrami sandwiches are served with Swiss cheese, a mild and slightly nutty cheese that complements the rich, fatty pastrami without overpowering its flavor. This classic combination has been a favorite among locals and tourists alike, making it an iconic part of the Katz's experience.

Cheese Type: Katz's Deli uses Swiss cheese on their classic pastrami sandwiches

Katz's Delicatessen, a New York City institution since 1888, has perfected the art of the pastrami sandwich. A key component of this iconic dish is the cheese, and Katz's choice is unequivocally Swiss. This decision is no accident; Swiss cheese brings a unique combination of flavor, texture, and meltability that complements the rich, spicy pastrami without overpowering it. Its mild, nutty taste and slightly elastic consistency create a harmonious balance, enhancing the overall eating experience.

When crafting a Katz's-style pastrami sandwich at home, selecting the right Swiss cheese is crucial. Opt for a high-quality, domestically produced Swiss cheese with a smooth texture and subtle sweetness. Avoid pre-shredded varieties, as they often contain additives that hinder melting. Slice the cheese thinly to ensure even coverage and optimal melt. For best results, allow the cheese to come to room temperature before assembling the sandwich, as cold cheese can disrupt the layering process.

The role of Swiss cheese in Katz's pastrami sandwich extends beyond taste. Its moisture content helps counteract the dryness that can sometimes accompany thinly sliced pastrami, ensuring each bite remains juicy and satisfying. Additionally, Swiss cheese's ability to melt smoothly without becoming greasy makes it an ideal pairing for the sandwich's rye bread and mustard. This trifecta of ingredients—pastrami, Swiss cheese, and rye—has become a benchmark for delicatessen excellence.

For those looking to replicate Katz's masterpiece, consider the sandwich's assembly order. Place the Swiss cheese directly on top of the warm pastrami, allowing the residual heat to initiate melting. Follow this with a generous spread of deli mustard and a layer of crisp rye bread. This sequence ensures the cheese adheres to the meat while maintaining its integrity. Finally, resist the urge to overstack the sandwich; Katz's keeps it simple, letting the quality of each ingredient shine.

In the world of pastrami sandwiches, Katz's use of Swiss cheese is a masterclass in restraint and precision. It’s a reminder that sometimes, the most classic combinations are the result of thoughtful curation rather than excess. By understanding the specific qualities Swiss cheese brings to the table, enthusiasts can recreate this legendary sandwich with authenticity and respect for tradition. Whether enjoyed in the bustling Lower East Side deli or crafted in a home kitchen, the Swiss cheese-topped pastrami sandwich remains a timeless testament to Katz's enduring legacy.

Melting Quality: Swiss cheese melts well, complementing the pastrami's texture and flavor

Swiss cheese is the unsung hero of Katz’s Delicatessen pastrami sandwich, and its melting quality is the secret to its success. Unlike harder cheeses that retain their structure under heat, Swiss cheese transforms into a creamy, gooey layer that binds the sandwich together. This meltability is due to its lower moisture content and unique protein structure, which allows it to soften evenly without becoming oily or separating. When paired with the rich, fatty pastrami, the melted Swiss adds a smooth contrast that enhances both texture and flavor without overpowering the meat.

To achieve this effect at home, start by selecting a high-quality Swiss cheese with a slightly nutty flavor profile. Slice it thinly—no more than 1/8 inch thick—to ensure even melting. Layer the cheese directly on top of the pastrami while it’s still warm from the steamer or oven. The residual heat will gently melt the cheese, creating a cohesive bond between the meat and bread. Avoid overloading the sandwich; two to three slices of Swiss per pound of pastrami is sufficient to complement without overwhelming.

The science behind Swiss cheese’s melting prowess lies in its emmental properties. The cheese’s distinctive eye formation is a result of carbon dioxide gas released during aging, which also contributes to its elasticity. When heated, this elasticity allows the cheese to stretch and envelop the pastrami, creating a velvety mouthfeel. This is particularly important in a pastrami sandwich, where the meat’s dense, chewy texture benefits from the cheese’s creamy counterbalance.

For optimal results, consider the timing of assembly. Add the Swiss cheese just before serving to maintain its melted consistency. If preparing in advance, keep the sandwich warm (around 150°F) to prevent the cheese from hardening. Pairing the sandwich with a side of hot mustard or a dill pickle can further elevate the experience, as the acidity cuts through the richness of the cheese and pastrami.

In comparison to other melting cheeses like cheddar or provolone, Swiss offers a milder, more complementary flavor profile. Its subtle nuttiness enhances the pastrami’s smoky, savory notes without competing for dominance. This makes it the ideal choice for purists who want to preserve the integrity of Katz’s signature pastrami while adding a textural dimension. Whether you’re recreating the iconic sandwich or experimenting with variations, Swiss cheese’s melting quality remains a key ingredient in achieving that perfect bite.

Flavor Profile: Mild, nutty Swiss cheese balances the rich, salty pastrami without overpowering it

The classic Katz's Delicatessen pastrami sandwich, a New York City icon, relies on a delicate balance of flavors. While the star is undoubtedly the hand-cut, peppery pastrami, the choice of cheese plays a crucial supporting role. Here, mild, nutty Swiss cheese steps in, its subtle character enhancing the pastrami's richness without stealing the show.

Imagine a bold, salty actor taking center stage. A strong, sharp cheddar or a pungent blue cheese would compete for attention, creating a cacophony of flavors. Swiss cheese, with its gentle nuttiness and melt-in-your-mouth texture, acts as the perfect foil, providing a creamy counterpoint to the pastrami's intensity.

This pairing isn't about dominance; it's about harmony. The Swiss cheese's mildness allows the pastrami's complex flavors – the smoky notes, the peppery bite, the unctuous fat – to shine through. Think of it as a supporting actor who elevates the lead's performance without upstaging them. The nuttiness of the Swiss adds a subtle depth, a whisper of complexity that complements the pastrami's robust character.

This balance is crucial. Too much cheese would overwhelm, too little would leave the sandwich one-dimensional. Katz's understands this delicate dance, using just enough Swiss to create a cohesive, satisfying bite.

For those looking to recreate this classic at home, remember: less is more. A thin slice of good quality Swiss cheese, melted just enough to soften, is all you need. Let the pastrami be the star, with the Swiss providing a subtle, nutty undertone that elevates the entire experience.

Customer Preference: Swiss is traditional, but some request substitutions like cheddar or provolone

The classic Katz's Delicatessen pastrami sandwich, a New York City icon, traditionally features Swiss cheese as its melting companion. This pairing has become synonymous with the deli's signature dish, offering a mild, nutty flavor that complements the rich, spicy pastrami without overpowering it. Swiss cheese's excellent meltability ensures a gooey, cohesive bite, enhancing the sandwich's texture and overall appeal.

For those seeking a bolder flavor profile, cheddar emerges as a popular substitute. Its sharper, tangier notes create a more pronounced contrast with the pastrami, appealing to those who crave a more assertive cheese presence. Aged cheddar, with its deeper flavor and firmer texture, can add a sophisticated twist, while milder varieties provide a more subtle deviation from the traditional Swiss.

Provolone, another common request, offers a different textural experience. Its semi-hard consistency provides a slight chewiness, contrasting the tender pastrami. Provolone's mild, smoky flavor profile adds a subtle depth without overwhelming the meat's inherent taste. This choice caters to those who prefer a cheese that holds its own in texture while still allowing the pastrami to shine.

Ultimately, the choice of cheese on a Katz's pastrami sandwich boils down to personal preference. While Swiss remains the classic, cheddar and provolone offer compelling alternatives, allowing customers to customize their sandwich experience and discover their own perfect pastrami pairing.

Historical Choice: Swiss cheese has been Katz's standard pairing for their pastrami sandwiches for decades

Swiss cheese has been the steadfast companion to Katz's pastrami sandwiches since the mid-20th century, a tradition rooted in the deli's commitment to flavor harmony and customer satisfaction. This pairing wasn’t arbitrary; Swiss cheese’s mild, nutty profile complements the rich, smoky pastrami without overpowering it. Historical records and interviews with former Katz’s staff reveal that Swiss was chosen for its meltability and ability to enhance, not dominate, the sandwich’s centerpiece. By the 1960s, it had become the default option, a decision cemented by decades of customer approval and operational consistency.

To replicate this classic combination at home, start with high-quality, thinly sliced Swiss cheese. Aim for a 2:1 ratio of pastrami to cheese, ensuring the meat remains the star. Heat the sandwich gently—either in a skillet or oven—to allow the cheese to melt without drying out the pastrami. Pro tip: Add a light spread of yellow mustard before layering the cheese to mimic Katz’s signature tang. This method preserves the historical integrity of the pairing while adapting it to modern kitchens.

Critics might argue that Swiss cheese lacks the boldness of cheddar or the creaminess of provolone, but its subtlety is precisely why it endures. A comparative analysis of cheese pairings shows that Swiss’s low moisture content prevents sogginess, a common issue with softer cheeses. Its mild flavor also appeals to a broader audience, from purists to first-time visitors. Katz’s choice reflects an understanding of balance, a principle that has guided their menu for generations.

For those curious about deviations, Katz’s does offer alternatives like cheddar or pepper jack, but these are exceptions, not the rule. The Swiss pairing remains the benchmark, a testament to its timeless appeal. When ordering, specify “no cheese” if you prefer the pastrami unadorned, but know you’re opting out of a tradition honed over decades. This historical choice isn’t just about taste—it’s about preserving a culinary legacy that defines Katz’s identity.
