ingredients

Italian sausage (mild or spicy)
Bell peppers (red, yellow, or green, sliced)
Onion (sliced)
Garlic (minced)
Olive oil
Pizza dough or refrigerated bread dough
Mozzarella cheese (shredded)
Provolone cheese (optional, for extra richness)
Italian seasoning
Salt and pepper
Egg (for egg wash)
Marinara or pizza sauce (for dipping, optional)

directions

I preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a skillet, I heat olive oil and sauté the sausage until browned and cooked through, breaking it up into crumbles.
I remove the sausage and sauté the sliced peppers and onions in the same pan until softened and slightly caramelized. I add garlic during the last minute.
I roll out the dough on a floured surface into a rectangle about 10×14 inches.
I layer mozzarella and provolone (if using), then spoon the sausage and veggie mixture over the cheese.
I sprinkle with Italian seasoning, salt, and pepper.
I fold the sides in slightly, then roll up the dough from the long edge like a jelly roll, sealing the seam and tucking the ends underneath.
I place it seam-side down on the baking sheet and brush the top with a beaten egg.
I make a few small slits on top to let steam escape and bake for 25–30 minutes, until golden brown.
I let it rest for 5–10 minutes before slicing and serve with warm marinara sauce.

Variations

Sometimes I add mushrooms or spinach to the filling for extra veggies. I’ve also made a spicy version with hot sausage and pepper jack cheese. For a leaner take, I use chicken or turkey sausage. If I want an herby flavor, I add fresh basil or oregano just before rolling the dough.

storage/reheating

I store leftovers wrapped in foil or in an airtight container in the fridge for up to 4 days. To reheat, I warm slices in a 350°F oven for about 10 minutes or in the air fryer for a crisp finish. It also freezes well—I slice, wrap, and freeze portions, then reheat directly from frozen when needed.

FAQs

Can I use store-bought dough?

Yes, I often use refrigerated pizza or bread dough for convenience. It bakes up golden and delicious every time.

What’s the best cheese for stromboli?

Mozzarella is my go-to for meltiness, but I like adding provolone or fontina for deeper flavor.

Can I make it vegetarian?

Absolutely. I replace the sausage with sautéed mushrooms, spinach, or roasted veggies for a hearty vegetarian version.

How do I keep the stromboli from getting soggy?

I cool the filling slightly before adding it to the dough, and I don’t overload it. Brushing the top with egg wash also helps it crisp up nicely.

Can I make this ahead of time?

Yes, I often assemble it earlier in the day and refrigerate it until I’m ready to bake. I just add a few extra minutes to the baking time if it’s cold.
