These loaded Philly Cheesesteak Stuffed Breadsticks pack juicy steak, caramelized vegetables, and gooey stretchy mozzarella inside buttery golden bread. Every mouthful delivers incredible flavor - tender beef, sweet sautéed onions and peppers, all wrapped in a warm, cheesy blanket that'll make your taste buds dance.
I whipped these up for a last-second football watch party, and they vanished before anything else I'd made. These days, friends and family beg me to make them whenever we get together, and I've tweaked the recipe to perfection after making them countless times.
What You'll Need
- Flank steak: Cut into thin slices so it cooks fast and stays soft
- Onion and bell pepper: They bring that classic Philly taste and natural sweetness
- Mushrooms: They add rich flavor and keep everything nice and moist
- Mozzarella cheese: Gives you that awesome stretchy pull with each bite
- Pizza dough: Makes the perfect wrapper - grab the ready-made stuff to save time
- Butter: Gets brushed on top for that stunning golden finish
- Parmesan cheese: Adds a nice salty kick that makes the filling pop
- Garlic powder: Brings that wonderful smell and taste that makes everyone hungry
Simple Steps to Make Them
- Getting Ready:
- Turn your oven on to 375°F and grab your skillet, baking sheet, rolling pin, and pastry brush. Roll your pizza dough into a big rectangle about 1/4-inch thick on a lightly floured counter. Making it even helps it bake right and makes the folding part easier later on.
- Making the Filling:
- Get your skillet hot with some olive oil over medium-high heat. Toss in those thin steak slices and cook them quick - just 2-3 minutes until they brown but stay juicy. Don't overcook or they'll get tough. Then throw in your sliced onions, peppers, and mushrooms right with the meat. Cook everything together for about 5-7 minutes until the veggies soften and start to brown. Add some salt and pepper, then take it off the heat and let it cool a bit so it won't melt your cheese too fast when you put it all together.
- Putting Them Together:
- Cut your dough into 2-inch strips with a knife or pizza cutter. Put some of your meat and veggie mix down the middle of each strip, but leave about half an inch around the edges so you can seal them. Sprinkle plenty of mozzarella over each one. The cheese tastes great and helps hold everything inside. Then roll each strip around the filling and pinch the edges closed. Put them seam-side down on a greased baking sheet with about an inch between them so they can grow.
- Finishing Up:
- Brush each breadstick with lots of melted butter to make them rich and golden. Sprinkle on some Parmesan and garlic powder for extra flavor. Bake them for 12-15 minutes until they turn golden brown and the cheese melts. They should be firm enough to pick up but still soft to bite. For extra crunch, you can broil them for the last minute or two, but watch them closely so they don't burn. Let them cool just a little before serving so the filling can set up.

My whole family can't get enough of the caramelized onions in this dish. My grandpa, who worked at a Philly diner for thirty years, taught me that letting onions cook slowly in the meat juices creates amazing flavor you just can't rush. Those sweet, rich onions are what turn these from good breadsticks into something you'll never forget.
Keeping Them Fresh
These tasty treats stay surprisingly good when you store them right. Once they've cooled completely, put them in a sealed container with parchment paper between layers so they don't stick together. They'll keep well in the fridge for up to 3 days. Want to save them longer? Wrap each one in foil, then put them all in a freezer bag and they'll last a month frozen. To enjoy them later, let refrigerated ones sit out for half an hour, then warm them in a 350°F oven for 8-10 minutes until they're hot and crispy again.
Ways to Change It Up
The standard recipe tastes great as is, but you can think of it as a starting point for tons of options. Want some heat? Throw in some jalapeños or a splash of hot sauce. Feeling like something different? Switch the steak for diced chicken and add sun-dried tomatoes and olives. Your veggie-loving friends will enjoy a version packed with sautéed peppers, onions, mushrooms and spinach plus extra cheese to hold it all together. You can even jazz up the dough by brushing it with garlic butter or sprinkling on some everything bagel seasoning before it goes in the oven.
What to Serve with Them
These breadsticks really hit the spot when served with the right sides and dips. Classic marinara offers a tangy contrast to the rich filling. Ranch dressing brings a cool creaminess that balances out all those bold flavors. For a full meal, serve them with a simple green salad dressed with vinaigrette - the fresh, tangy greens cut through the richness. When friends come over to watch the game, set them out alongside buffalo wings and veggie trays for a spread that'll make everyone happy.
