Baked High-Protein Pepperoni Stromboli (Printable Version)

Italian-American stromboli with beef, pepperoni, and mozzarella. Golden-baked perfection in 50 minutes.

# The Ingredients You'll Need:

→ 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 egg, beaten for egg wash
12 - 1 tablespoon olive oil
13 - Marinara sauce for serving

# Step-by-Step Instructions:

01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Heat olive oil in a large skillet over medium heat. Sauté onions 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 as it cooks. Season with salt, pepper, Italian herbs, and red pepper flakes. Cook until browned and no longer pink, approximately 5 to 7 minutes. 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 - Evenly distribute the cooled beef mixture over the dough, leaving a 1-inch border on all sides. Layer pepperoni slices over the beef. Sprinkle mozzarella and Parmesan cheeses evenly across the top.
06 - Starting from a long edge, tightly roll the dough into a log. Pinch the ends and seam securely to seal.
07 - Place the stromboli seam-side down on the prepared baking sheet. Brush the top with beaten egg. Using a sharp knife, make 3 to 4 diagonal slits across the top to allow steam to escape.
08 - Bake for 25 to 30 minutes until golden brown and cooked through. Allow to rest for 5 minutes before slicing.
09 - Slice the stromboli and serve with warm marinara sauce.

# Additional Tips::

01 -
  • It delivers serious protein without feeling heavy, thanks to lean beef and two kinds of cheese working together.
  • The golden, crispy crust gives way to gooey, spiced filling that tastes like pizza upgraded to comfort food status.
  • You can prep it ahead, refrigerate, and bake it right before dinner when everyone is starving.
  • Slicing it reveals those beautiful swirls of meat and cheese that make you look like a kitchen genius.
02 -
  • Let the beef cool before spreading it on the dough, or the heat will make the dough sticky and hard to roll.
  • Do not skip sealing the seam tightly, because any gaps will leak cheese and filling all over your baking sheet.
  • If your dough keeps shrinking back, cover it with a towel and let it rest for 10 minutes to relax the gluten.
03 -
  • Brush the egg wash gently so you do not deflate the dough or disturb the seam.
  • Use a pizza cutter or serrated knife to slice cleanly through the crust without squishing the filling.
  • If you want extra flavor, sprinkle a little garlic powder or dried oregano on top of the egg wash before baking.
