Mozzarella Cheesesteak Stromboli
Flaky pizza dough filled with tender steak, sautéed peppers, onions, and melted mozzarella cheese. A hearty Italian-American fusion that's perfect for dinner or game day.

The Perfect Fusion of Flavors
This stromboli masterfully combines the classic Philadelphia cheesesteak flavors with traditional Italian stromboli technique. The key is properly sautéing the vegetables until caramelized and cooking the steak just until tender to prevent overcooking during baking.
The mozzarella cheese serves as both a flavor component and a binding agent, melting beautifully to hold all the ingredients together while creating those irresistible cheese pulls when sliced. The pizza dough becomes golden and crispy outside while staying tender inside.
💡 Professional Tip
Let the filling cool slightly before assembling to prevent the cheese from melting too quickly and making the dough soggy during assembly.
Frequently Asked Questions
Absolutely! Store-bought pizza dough works perfectly and saves time. Let it come to room temperature for easier rolling and stretching.
Ribeye is ideal for its tenderness and flavor, but sirloin or even deli roast beef can work. Slice very thin against the grain for best texture.
Make sure vegetables and steak are well-drained and not too hot when assembling. Use parchment paper and don't overfill the stromboli.
Yes, assemble and refrigerate for up to 4 hours before baking. You may need to add 2-3 extra minutes to the baking time if cooking from cold.
Let the dough rest for 10-15 minutes if it's too elastic. Make sure it's at room temperature and work gently to avoid overworking the gluten.
Yes, wrap cooled slices individually and freeze for up to 3 months. Reheat in a 350°F oven until heated through.
Provolone is traditional for cheesesteaks, or try a blend of mozzarella and provolone. Sharp cheddar also works well for a different flavor profile.
The egg wash is essential for color and shine. Brush evenly and bake at the right temperature - too low won't brown properly, too high might burn.
Recipe Troubleshooting Guide
Dough Tears
Problem: Pizza dough tears while rolling or assembling
Solution: Let dough come to room temperature, work gently, and patch small tears with extra dough. Don't overstretch - roll gradually.
Filling Leaks Out
Problem: Cheese and filling leak during baking
Solution: Don't overfill, seal edges properly with water, and ensure steam vents are adequate. Place seam-side down for baking.
Undercooked Center
Problem: Dough is golden but center is still raw
Prevention: Lower oven temperature to 400°F and bake longer, or tent with foil if browning too quickly. Check internal temperature reaches 190°F.
Dry Filling
Problem: Steak and vegetables are dry after baking
Recovery: Don't overcook the steak initially, add a bit more butter or oil, and ensure vegetables retain some moisture during sautéing.
Soggy Bottom
Problem: Bottom crust is soggy and undercooked
Prevention: Use parchment paper, ensure filling isn't too wet, and bake on the bottom rack for better bottom browning.
Flavor Balance Issues
Too Sweet: Add more black pepper, garlic, or a pinch of red pepper flakes
Too Salty: Serve with fresh marinara sauce or add more vegetables to balance
Bland: Increase seasoning on steak, add more garlic, or use aged provolone cheese

Selecting Quality Ingredients
The quality of your steak significantly impacts the final result. Choose well-marbled ribeye or sirloin and slice it paper-thin when partially frozen for easier cutting. Fresh pizza dough from your local pizzeria often yields better results than frozen varieties.
Use a combination of bell peppers for color and flavor - red, yellow, and green peppers each bring different sweetness levels. Fresh mozzarella can be used but should be well-drained, while low-moisture mozzarella provides better melting consistency.
Essential Ingredient Notes
- Steak Selection: Ribeye provides the best flavor and tenderness. Freeze for 30 minutes before slicing for paper-thin cuts that cook quickly and stay tender.
- Pizza Dough: Fresh dough from a pizzeria is ideal, but quality frozen dough works well. Ensure it's completely thawed and at room temperature before use.
- Cheese Choice: Low-moisture mozzarella melts best without making the stromboli soggy. Part-skim varieties provide good flavor without excess grease.

Mastering the Assembly Technique
The key to perfect stromboli lies in the proper layering and sealing technique. Distribute fillings evenly but don't overfill, leaving adequate borders for sealing. The cheese should be divided between bottom and top layers to help bind everything together.
Sealing is crucial - use a little water to help the dough edges stick together, and make sure to place the stromboli seam-side down on the baking sheet. The steam vents prevent bursting while allowing proper cooking throughout.
Perfect Sealing
Brush edges with water, fold over filling, and pinch firmly to seal. Roll slightly to even out the shape and ensure no air pockets remain.
