Preparation

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

Step 2: Cook the Steak and Vegetables

In a skillet over medium-high heat, heat 1 tablespoon olive oil. Add the sliced onions and bell peppers, cooking until they soften (about 3-5 minutes). Add the garlic and cook for another 30 seconds. Remove and set aside.

In the same pan, add the thinly sliced ribeye steak. Season with salt, black pepper, Italian seasoning, and red pepper flakes. Cook until browned (about 3-4 minutes). Remove from heat and let cool slightly.

Step 3: Roll Out the Dough

On a floured surface, roll out the pizza dough into a 12×16-inch rectangle. If the dough is too sticky, lightly flour your hands and rolling pin.

Step 4: Assemble the Stromboli

Spread an even layer of mozzarella cheese and provolone over the dough, leaving a 1-inch border around the edges. Add the cooked steak, onions, and peppers evenly on top.

Step 5: Roll and Seal

Starting from the long side, carefully roll the dough into a log, tucking in the sides as you go. Pinch the edges to seal the stromboli tightly.

Step 6: Egg Wash and Bake

Transfer the stromboli to the prepared baking sheet, seam-side down. Brush the top with a beaten egg and melted butter, then sprinkle with Parmesan cheese.

Bake for 25-30 minutes, or until golden brown and crispy.

Step 7: Slice and Serve

Let the stromboli cool for 5 minutes, then slice into pieces and serve with marinara sauce for dipping.
