# Components:
→ Dough
01 - 1 pound pizza dough, store-bought or homemade
→ Meat & Cheese Filling
02 - 8 ounces lean ground beef
03 - 2 ounces pepperoni slices
04 - 2 cups shredded mozzarella cheese
05 - 1/2 cup grated Parmesan cheese
→ Vegetables & Seasoning
06 - 1/2 cup chopped onions
07 - 2 cloves garlic, minced
08 - 1 teaspoon dried Italian herbs
09 - 1/4 teaspoon crushed red pepper flakes, optional
10 - Salt and black pepper to taste
→ Extras
11 - 1 large egg, beaten for egg wash
12 - 1 tablespoon olive oil
13 - Marinara sauce for serving
# Method:
01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Heat olive oil in a large skillet over medium heat. Add onions and sauté for 2 to 3 minutes until translucent. Add minced garlic and cook for 30 seconds until fragrant.
03 - Add ground beef to the skillet, breaking it apart with a spoon as it cooks. Season with salt, pepper, Italian herbs, and red pepper flakes. Cook for 6 to 8 minutes until browned and no longer pink. Remove from heat and cool for 5 minutes.
04 - On a lightly floured surface, roll out pizza dough into a large rectangle approximately 12 by 16 inches.
05 - Spread the cooled beef mixture evenly over the dough, leaving a 1-inch border on all sides.
06 - Layer pepperoni slices over the beef mixture. Sprinkle mozzarella and Parmesan cheeses evenly over the pepperoni.
07 - Starting from a long edge, tightly roll the dough into a log. Pinch the ends and seam firmly to seal.
08 - Place the stromboli seam-side down on the prepared baking sheet. Brush the entire top surface with beaten egg using a pastry brush.
09 - Using a sharp knife, make 3 to 4 diagonal slits across the top to allow steam to escape during baking.
10 - Bake for 25 to 30 minutes until the top is golden brown and the stromboli is cooked through. Allow to rest for 5 minutes before slicing.
11 - Slice the stromboli into individual portions and serve immediately with warm marinara sauce.
