How to Make an Authentic Philly Cheesesteak on the LoCo Griddle

Making an authentic Philly cheesesteak on the LoCo griddle brings restaurant-style results to your backyard. Using a large, zoned griddle such as the LoCo 36″ SmartTemp gives you the surface area and fast heat recovery needed to sear a big batch of thinly sliced beef and caramelize onions without lowering the temperature. The griddle’s precise temperature control helps you manage separate zones for searing, caramelizing, and keeping rolls warm so every sandwich comes out consistent and perfectly built.

Focus on the classic trio: thinly sliced ribeye (or a comparable cut), diced onions, and plenty of melty cheese. The three-burner layout lets you sear the steak on high while gently toasting the rolls on the low zone, and keeping onions warm on a cooler side. When the beef is browned, chopped, and topped with melted provolone, the result is a beef-forward, savory sandwich that’s ideal for game day or any crowd feed.

Step 1: Selecting and Slicing the Beef

Start with a well-marbled cut so the fat renders quickly under high heat, creating both flavor and tenderness. Ribeye is the classic choice; top sirloin or thinly sliced strip steak work well too. If available, pre-sliced steaks save prep time and are ideal for feeding a crowd. For home prep, chill the steak in the freezer for 30–45 minutes so it firms up, then slice it paper-thin with a very sharp knife against the grain.

• Boneless chuck roast: Use only after trimming heavy connective tissue; a budget-friendly option.
• Pre-sliced strip or wagyu slices: Convenient and richly flavored when available.
• Ribeye steak: The traditional favorite for its fat content and tenderness.
• Top sirloin roast: A leaner, economical alternative when sliced very thin.

Step 2: Prepping the Aromatics and Bread

Dice one large yellow onion into uniform pieces so they cook evenly and caramelize at the same rate as the beef. Split your hoagie rolls down the center without cutting through the hinge so they open like a book and hold the filling. Keep the rolls covered until ready to toast; a good quality roll makes a huge difference in structure and mouthfeel.

Step 3: Zonal Griddle Setup and Initial Heat

Preheat the LoCo griddle with three zones: a high-heat sear zone, a middle zone around 400°F for steady cooking, and a low zone to keep rolls and finished components warm. Wait for the griddle to reach temperature before adding meat. Add a mix of vegetable oil and unsalted butter to create a non-stick, flavor-rich surface—move the fat with your spatula so it coats the cooking area evenly.

Step 4: Caramelizing the Onions

Place the diced onions on the seasoned middle zone and cook them until soft and translucent with slightly charred edges—about 5–6 minutes. Toss them frequently with metal spatulas to ensure even contact and coating with the cooking fat. Spread them thinly on the griddle to speed caramelization, then move the cooked onions to the low zone to keep warm while you sear the beef.

• Cool Zone Transition: Keeps the onions warm and ready for assembly.
• Cooking Time: 5–6 minutes until translucent and slightly browned.
• Middle Zone: Best at approximately 400°F for steady caramelization.

Step 5: Searing and Seasoning the Beef

Add more oil and butter to the hot sear zone, then spread the thinly sliced steak in an even layer so it sears instead of steams. Season immediately with kosher salt and freshly cracked black pepper so the seasoning bonds with the rendering fat and forms a savory crust. Stir and break the strips periodically; cooking takes roughly ten minutes until the meat is well browned. Use metal spatulas to chop and agitate the beef on the hot steel for superior texture.

Step 6: Integrating the Onions and Portioning the Meat

Scoop the caramelized onions into the browned beef so the sweet aromatics and meat juices combine. Slide the mixture toward the cooler side of the griddle and divide it into four equal rectangular portions to match your hoagie rolls. Use the spatula edge to separate the piles cleanly so each sandwich receives an even, generous filling without overcooking the meat.

Step 7: Toasting the Mayo-Smeared Rolls

Spread a thin layer of mayonnaise on the inside of each split hoagie roll before placing cut-side down on the low zone. Mayonnaise browns nicely and creates a crisp interior that resists sogginess from the meat’s juices. Toast slowly for 3–5 minutes until golden and fragrant—lift an edge with a spatula to monitor color.

Step 8: Melting the Provolone Cheese

Top each meat portion with two slices of provolone. Lower the griddle lid briefly (about 60 seconds) to trap heat and steam for a consistent melt from the top down. Watch for bubbling and translucence at the edges—when the cheese clings to the beef, it’s ready for assembly.

Step 9: The Final Scoop and Assembly

Place a toasted roll on top of a cheesy meat pile, slide a spatula fully under the mixture, and lift it into the roll in one smooth motion. Give the sandwich a firm squeeze so the provolone binds the meat to the bread. Repeat for all portions, keeping sandwiches on the warm zone until ready to wrap.

Step 10: The Foil Wrap and Final Rest

Wrap each finished sandwich tightly in aluminum foil to trap residual heat and steam for 5–10 minutes. This softens the roll and helps the cheese permeate the meat for a cohesive, restaurant-style bite. After resting, slice diagonally with a sharp serrated knife and serve.

Using a zonal griddle method gives you control over textures—crispy sear, sweet caramelized onions, and a warm, resilient bun—so you can produce consistent, championship-quality cheesesteaks for a crowd. The final steam step in foil is what turns a good sandwich into the classic, unified Philly experience.

Serving Suggestions for a Championship Spread

Pair these hearty sandwiches with a bright or crunchy side to balance the richness. Crinkle-cut fries, potato chips, or spicy pickled cherry peppers bring contrast. For a classic regional pairing, offer a cold lager or a small bowl of au jus; extra Cheez Whiz is an option for those who prefer it on the side.

• Yuengling Traditional Lager: A classic pairing that cuts through the fat.
• Pickled Peppers: A sharp, vinegary contrast to refresh the palate.
• Potato Chips or Fries: Add salty crunch to complement the steamed roll.

People Also Ask (PAA)

• What is the best cut of meat for a Philly cheesesteak? Ribeye is preferred for its marbling and tenderness; top sirloin or flank can work if sliced paper-thin against the grain.
• Can I use different cheeses? Provolone and Cheez Whiz are traditional. White American melts smoothly and is commonly used. Avoid hard aged cheeses that won’t melt evenly.
• How do I get paper-thin steak at home? Chill the beef in the freezer for 30–45 minutes until firm but not frozen solid; it slices much easier and yields thin, translucent pieces.
