  • 1 green bell pepper, thinly sliced

  • 1 medium yellow onion, thinly sliced

  • 2 cloves garlic, minced

How to Prepare the Stromboli

 Step 1: Prepare the Dough (Skip if using pre-made pizza dough)

  1. Activate Yeast:
    In a small bowl, combine warm water, sugar, and yeast. Let sit for 5–10 minutes until foamy.

  2. Make the Dough:
    In a large mixing bowl or stand mixer, add flour and salt. Pour in the yeast mixture and olive oil. Mix until a dough forms. Knead for 8–10 minutes by hand or 5–6 minutes with a dough hook.

  3. Let It Rise:
    Place the dough in a greased bowl, cover with a towel or plastic wrap, and let it rise in a warm place for about 1 hour or until doubled in size.

 Step 2: Cook the Sausage, Peppers, and Onions

  1. Brown the Sausage:
    Heat a large skillet over medium-high heat. Cook the sausage, breaking it up into crumbles, until browned and cooked through. Remove and set aside.

  2. Sauté the Vegetables:
    In the same skillet, add a little olive oil if needed. Add the sliced onions and bell peppers. Cook until softened and slightly caramelized (about 8–10 minutes). Add the garlic and cook another 1–2 minutes.

  3. Combine:
    Return the sausage to the skillet. Season with oregano, salt, pepper, and red pepper flakes. Mix thoroughly. Set aside to cool slightly before assembling.

 Step 3: Assemble the Stromboli

  1. Preheat Oven:
    Set oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.

  2. Roll Out the Dough:
    On a lightly floured surface, roll the dough into a large rectangle, approximately 12×15 inches.

  3. Add the Filling:
    Leaving a 1-inch border around the edge, layer mozzarella and provolone down the center. Top with the sausage, peppers, and onion mixture.

  4. Roll It Up:
    Fold the long sides over the filling and roll like a jelly roll, sealing the seam tightly. Tuck in the ends. Place seam-side down on the prepared baking sheet.

  5. Add Toppings:
    Brush with egg wash. Sprinkle garlic powder and Parmesan on top if desired. Use a sharp knife to cut a few diagonal slits on top for steam to escape.

 Step 4: Bake

  1. Bake:
    Bake for 25–30 minutes until golden brown and cooked through.

  2. Cool:
    Allow the stromboli to rest for 5–10 minutes before slicing.

 Step 5: Serve

Slice into thick pieces and serve warm with warm marinara or pizza sauce for dipping.

 Pro Tips & Tricks

  1. Shortcut Dough:
    Store-bought pizza dough works great for a time-saving version.

  2. Make Ahead:
    You can prep the filling a day in advance. Store it in the fridge and assemble the stromboli just before baking.

  3. Vegetarian Option:
    Swap the sausage for sautéed mushrooms or a meatless sausage alternative.

  4. Cheese Options:
    Swap mozzarella for fontina, cheddar, or smoked gouda for a different flavor profile.

  5. Freeze for Later:
    Stromboli freezes beautifully. Wrap tightly in foil and store for up to 2 months. Bake directly from frozen at 375°F until heated through (about 25–30 minutes).

  6. Double Up:
    Make two strombolis at once—freeze one, eat the other.

 Variations to Try

  1. Spicy Stromboli:
    Use hot Italian sausage and extra red pepper flakes.

  2. Breakfast Stromboli:
    Fill with scrambled eggs, breakfast sausage, cheddar, and hash browns.

  3. Philly Cheesesteak Version:
    Replace sausage with thinly sliced steak, onions, and provolone.

  4. Pepperoni Pizza Stromboli:
    Classic kid-favorite: mozzarella, marinara, and lots of pepperoni.

 Perfect Pairings

  • Drink: Pair with a chilled glass of Chianti or a cold IPA.

  • Side Dish: Serve with Caesar salad, garlic knots, or a tangy coleslaw.

  • Dessert: Follow up with cannoli, tiramisu, or a slice of ricotta cheesecake.

 Leftovers & Storage

  • Refrigerator: Store leftovers in an airtight container for up to 4 days.

  • Reheat: Warm in a toaster oven or 350°F oven for 10 minutes. Avoid microwaving to preserve the crust’s crispness.

 FAQs

Can I use puff pastry instead of pizza dough?

Yes, but reduce the baking time slightly (20–25 minutes). It will have a flakier texture.

Can I add marinara sauce inside the stromboli?

While not traditional, yes. Just avoid adding too much or it can make the dough soggy. A few spoonfuls on the filling is enough.

What’s the difference between a calzone and stromboli?

A calzone is usually a folded pizza dough half-moon with sealed edges, while stromboli is rolled and sliced more like a sandwich or pinwheel.
