Best Cheesesteak Stromboli Recipe

Preheat the oven to 400 F.

Heat a large nonstick skillet to medium-high.

Place 2 to 3 steaks in the pan at a time, then cook them for about 1 minute and 30 seconds on each side. Remove them from the pan, and set aside.

Cook the remaining steaks in batches until they are all cooked. Then, wipe the pan clean.

In the same skillet on medium-high heat, add the vegetable oil.

Add the onions and peppers to the pan, and sprinkle them with salt and pepper.

Sauté the peppers and onions for 2 to 3 minutes, until the onions are lightly browned.

On a piece of lightly floured parchment paper, roll out the pizza dough into a 15x10-inch rectangle.

Lay the sliced provolone cheese onto the dough, leaving about ½ inch of room on the sides. Top the cheese with the cooked steak. Add the peppers and onions on top of the steak. Top the peppers and onions with the shredded mozzarella cheese.

Fold in the sides of the dough, and then roll the dough up. Pinch the seams to seal. Make sure the stromboli is seam-side down on the parchment paper.

Place the parchment paper with the stromboli onto a baking sheet.

Combine the egg and the water in a small bowl, and beat until well combined. Brush the egg mixture over the dough.

Cut slits in the top of the dough.

Bake the stromboli in the preheated oven for 15 to 20 minutes, until golden brown.

If desired, add some mozzarella or Parmesan cheese on top, and cook for another 5 minutes.

Let stand for 10 minutes, then cut and serve.
