These Philly cheesesteak sloppy joes are meaty, cheesy, and packed with classic cheesesteak flavor—made easy with ground beef, peppers, onions, and melty mozzarella, all piled onto toasted brioche buns.
Start by melting butter in a large skillet over medium heat. It kinda sets the base flavor, so don’t skip it.
Add the diced onion and green bell pepper. Cook till they soften up, bout 5 minutes. You’ll notice the smell's already turning awesome.
Throw in the ground beef and brown it all up. Break it apart with a spoon so it cooks evenly.
Stir in beef broth, ketchup, Worcestershire sauce, kosher salt, and fresh ground pepper. Mix it all good so flavors get married.
Bring this whole mixture to a simmer, then let it cook for 10 minutes. You’ll hear the valve hiss as pressure builds in your cooker nearby.
In a small bowl, mix cornstarch with a bit of water to make a smooth slurry. Stir that into your skillet and cook another minute till the sauce thickens just right.
Finally, dump that cheesy beef mixture onto your buns. You can melt the cheddar or mozzarella on top or stir it right in. Either way, you got yourself a messy, tasty dinner!
Notes
This Philly cheesesteak sloppy joe meat can be frozen for 6 months. Reheat gently to keep the texture.
