The Origins of the Philly Cheesesteak
A Brief History of the Iconic Sandwich
The story of the Philly cheesesteak begins in South Philadelphia in the 1930s. Pat Olivieri, a hotdog vendor, is credited with creating the first cheesesteak when he decided to toss thinly sliced beef onto his grill. The aroma wafted through the streets, attracting the attention of a passing cab driver, who requested a steak sandwich on the spot. Word spread, and soon, Pat’s King of Steaks was born, setting the foundation for this beloved sandwich.
Originally, the Philly cheesesteak didn’t include cheese. The addition of provolone came later, followed by Cheese Whiz in the 1950s. These variations gave birth to heated rivalries among cheesesteak purists. Whether you’re team provolone or team Whiz, one thing remains clear: the Philly cheesesteak is an irreplaceable part of Philadelphia’s food heritage.
The Traditional Ingredients That Made It Famous
At its core, the Philly cheesesteak is simple yet extraordinary. The sandwich’s foundation is ribeye steak, celebrated for its balance of marbling and tenderness. Thinly sliced and cooked on a flat-top grill, the beef delivers a savory and melt-in-your-mouth experience.
The hoagie roll, another crucial element, is sturdy enough to hold the juicy meat without becoming soggy. Toppings like caramelized onions add sweetness and depth, while cheese—whether it’s provolone, American, or the iconic Cheese Whiz—brings creaminess to every bite.
These humble ingredients, combined with a pinch of seasoning and a skilled hand, created a sandwich that has stood the test of time. But as we’ll explore in later sections, a modern twist involving a secret ingredient has brought the Philly cheesesteak into a new era of deliciousness.
Breaking Down the Ingredients: What Sets a Cheesesteak Apart?
The Role of Ribeye Steak: Why It’s the Best Choice
The heart of a Philly cheesesteak lies in its beef, and there’s no better cut than ribeye steak. Known for its balance of tenderness and flavor, ribeye has the right amount of marbling to produce juicy, flavorful slices when cooked. Thin slicing is crucial—it ensures quick, even cooking and maximizes the melt-in-your-mouth texture this sandwich is famous for.
Cooking on a flat-top grill seals in the juices while allowing the fat to caramelize. This results in that distinct savory profile that defines an authentic cheesesteak. When paired with complementary ingredients, the ribeye becomes the star, holding its own against bold flavors like caramelized onions and tangy cheese.
Hoagie Rolls: A Subtle but Critical Component
While often overlooked, the hoagie roll is a critical ingredient that makes or breaks a cheesesteak. The ideal roll should be sturdy yet soft, with just the right amount of chew to soak up the steak’s juices without falling apart. A lightly toasted roll adds a touch of crunch and enhances the sandwich’s structure.
Many cheesesteak purists swear by Amoroso rolls, a Philadelphia staple, but any high-quality hoagie roll can work. Remember, the bread’s job is to complement the filling, not overshadow it.
Onions and Cheese: The Classic Duo
The combination of sautéed onions and melted cheese adds depth to the Philly cheesesteak. Onions, when caramelized to golden perfection, provide a hint of sweetness that balances the steak’s richness. Meanwhile, the cheese—whether it’s provolone, American, or the iconic Cheese Whiz—ties everything together with its creamy texture.
Each cheese offers its unique touch: provolone for a sharp, tangy bite; American for mild, melty goodness; and Cheese Whiz for a nostalgic, bold flavor. Whatever your preference, this duo ensures every bite bursts with layers of savory satisfaction.
What Is the Secret Ingredient in Philly Cheesesteak?
What Is Kewpie Mayo? The Hidden Star
So, what is the secret ingredient in Philly cheesesteak? The answer might surprise you: Kewpie mayo. This Japanese-style mayonnaise is a game-changer, thanks to its rich, creamy texture and subtle tang. Unlike regular mayo, Kewpie uses egg yolks only, resulting in a luxurious mouthfeel that elevates the sandwich to gourmet status.
Adding a thin layer of Kewpie mayo to the roll or drizzling it atop the steak introduces an unexpected burst of umami. This secret ingredient doesn’t overshadow the traditional flavors but instead enhances them, creating a cheesesteak experience that’s anything but ordinary.
Why Kewpie Mayo Elevates Flavor
The magic of Kewpie mayo lies in its ability to amplify other ingredients. Its slight tang complements the caramelized onions, cutting through their sweetness and balancing the overall flavor. It also works wonders with melted cheese, ensuring every bite feels indulgent yet balanced.
For those who might balk at adding mayo to a cheesesteak, rest assured—it doesn’t taste overly “mayo-like.” Instead, it acts as a flavor enhancer, taking this already iconic sandwich to the next level.
How It Compares to Other Popular Additions
While many cheesesteak enthusiasts experiment with extra toppings like mushrooms or peppers, Kewpie mayo stands out for its subtlety and effectiveness. It doesn’t compete with the main ingredients but enhances them, making it the ultimate finishing touch. Unlike ketchup or hot sauce, which can overpower the steak’s natural flavors, Kewpie mayo seamlessly blends into the sandwich’s profile.
Essential Cooking Techniques for the Best Philly Cheesesteak
Prepping the Steak for Maximum Tenderness
To create the perfect Philly cheesesteak, the steak’s texture and flavor are paramount. Start with ribeye steak, which should be as thinly sliced as possible. If you’re slicing it yourself, try partially freezing the steak first—this firms up the meat and makes thin slicing a breeze.
Season the steak with a pinch of salt and pepper before cooking. A flat-top grill works best for cheesesteaks, as it evenly distributes heat and allows the steak to develop a golden crust while staying juicy. For even more flavor, a quick drizzle of Worcestershire sauce while cooking can enhance the steak’s umami profile.
Perfectly Caramelizing Onions for Sweetness
Caramelized onions add a touch of sweetness that balances the richness of the steak and cheese. To achieve this, slice the onions thinly and cook them slowly over medium heat with a bit of butter or olive oil. Stir frequently to ensure they brown evenly without burning.
As the onions caramelize, their natural sugars develop, creating that irresistible golden-brown hue. Add a pinch of sugar or a splash of balsamic vinegar for a deeper flavor, but don’t overpower their natural sweetness.
Toasting the Hoagie Roll: A Game-Changer
Toasting the hoagie roll is a small step with a big impact. Spread a thin layer of softened butter or Kewpie mayo on the cut sides of the roll, then place it face down on a hot skillet or flat-top grill. Toasting adds a subtle crunch that contrasts beautifully with the tender steak and creamy cheese.
The toasted roll also holds up better against the juicy filling, ensuring every bite is satisfying without becoming messy.
Regional Variations of the Philly Cheesesteak: Classic vs. Modern
Traditional Philly Cheesesteak Versus Modern Twists
While the classic Philly cheesesteak remains a favorite, regional variations and modern twists have added exciting diversity to this iconic dish. In Philadelphia, purists stick to the essentials: ribeye steak, caramelized onions, Cheese Whiz (or provolone), and a hoagie roll. These ingredients, when done right, create a sandwich that’s hard to beat.
However, outside Philly, chefs and home cooks alike experiment with new toppings and flavors. Mushrooms, bell peppers, and even jalapeños are popular additions for those seeking extra texture or spice. Some even swap the steak for chicken, giving rise to the equally beloved chicken cheesesteak.
Other Secret Ingredients People Swear By
While Kewpie mayo is arguably the best answer to what is the secret ingredient in Philly cheesesteak, other contenders have also gained popularity. Garlic butter, truffle oil, and chipotle aioli have all been used to elevate the sandwich’s flavor. These ingredients, though unconventional, cater to those looking to add a unique twist to a classic recipe.
