Giant Stuffed Philly Cheesesteak Meatballs

Imagine a crispy, seared beef meatball the size of your fist, hiding a molten core of provolone, caramelized onions, and tender peppers. That's exactly what you get with these giant stuffed Philly cheesesteak meatballs.

They're a playful, over-the-top twist on the classic sandwich—all the savory flavors you love, wrapped in juicy ground beef and baked until the cheese erupts. Serve them with a warm cheese sauce for dipping, and watch them disappear.

These giant stuffed meatballs take everything great about a Philly cheesesteak—rich beef, sweet peppers, onions, and gooey cheese—and turn it into a hearty, shareable dinner. The key is building layers: a well-seasoned beef mixture, a generous cheese center, and a quick sear that locks in juices before the oven finishes the job.

The result is a crispy exterior, a tender, flavorful interior, and a cheese pull that steals the show. Perfect for game day, family dinner, or any night you want something impressive without hours of work.

Ingredients

Why this recipe works

The method here is all about contrast. Searing the meatballs in a hot cast iron skillet creates a deeply browned crust that adds a savory, almost smoky flavor.

Then, finishing them in the oven ensures the interior cooks evenly without burning the outside, while the provolone cubes melt into a molten pocket. This two-step process gives you that perfect crispy-meets-tender texture in every bite.

Stuffing the meatballs with provolone rather than mixing the cheese into the meat means you get a dramatic, melty center that stays distinct from the beef. The caramelized onions and peppers, sautéed in butter and Worcestershire, add sweetness and umami that echo the classic Philly filling.

By shaping the meat around the cheese, you create a sealed pocket that keeps the cheese contained until you bite into it—or pull it apart for that viral-worthy stretch.

Notes and substitutions

Use ground beef with a higher fat content, like 80/20, for the juiciest meatballs. Leaner beef can dry out during the long bake. The breadcrumbs and eggs help bind the mixture, so the meatballs hold their shape while still staying tender. Make sure the sautéed vegetables are cooled before mixing them in, so they don't cook the eggs or make the meat greasy.

Provolone is the classic choice for this dish, but any good melting cheese will work. Cut the cheese into uniform cubes so they melt evenly. For the sauce, processed cheese melts the smoothest, but a homemade cheddar sauce can be substituted. The cast iron skillet is ideal for searing and going straight into the oven, but any oven-safe skillet will do.

• Ground beef (80/20): Ground chuck or ground sirloin; adjust fat content as needed. For leaner beef, add a tablespoon of olive oil to the mixture.
• Provolone cheese: Low-moisture mozzarella, fontina, or white American cheese can be used. Ensure it melts well.
• Processed cheese for sauce: Use a homemade cheese sauce with cheddar and milk, or skip the sauce and serve with extra provolone.
• Plain breadcrumbs: Panko breadcrumbs work well; reduce to 3/4 cup if using panko.
