Italian sausage stromboli is a golden, baked pizza dough roll filled with savory Italian sausage, melted mozzarella, and Italian seasonings, served warm with marinara sauce for dipping.
Preheat the oven to 425°F. Line a large baking sheet pan with parchment paper or a silicone baking mat. (OR spray the pan with cooking spray)
In a medium-size skillet saute the onion in a couple of drizzles of olive oil for 2 minutes or until softened. Add garlic and saute for 1 minute longer. Add Italian sausage to the pan, cook until no pink remains. Drain any excess fat from the pan. Set aside.
Roll or pat dough, stretching a 12x16-inch rectangle. Sprinkle with half of the shredded mozzarella cheese.
Arrange the cooked sausage over cheese then drizzle with the pizza sauce.
Top with the remaining shredded cheese. Begin to roll starting from the widest edge. Transfer seam side down on the prepared baking sheet pan.
Brush the top and sides with melted butter, then sprinkle with Italian seasoning onion powder and garlic salt. Finish with Parmesan cheese.
Bake for 18-20 minutes or until golden brown and cooked through. Remove from the oven and let stand for 5 minutes before cutting into 1-inch slices.
Serve with additional pizza sauce for dipping, if desired.
Notes
Refrigerated Pizza Dough - I purposely use refrigerated pizza dough for this stromboli as it was designed to bake quickly and thoroughly. No yeast required! Afterall, the goal here is an easy weeknight meal.
Using Homemade Pizza Dough - Should you choose to use homemade pizza dough, be aware it should be rolled very thin or it won't bake all the way through. Alternately, form homemade dough into a circle, fill one side then fold it over and pinch the crust like a calzone. Homemade pizza dough will bake more thoroughly when making it this way.
Protein - You can use mild or spicy Italian sausage for this recipe. You could also use turkey sausage, chicken sausage or ground beef.
Additional Pizza Toppings - You could add mushrooms, black olives or bell peppers to the filling.
Fresh Herbs - You can also add fresh herbs like oregano, fresh basil, and rosemary.
Pizza Sauce - Use a prepared jar of pizza sauce that you enjoy for a timesaver. If you'd like to make your own homemade pizza sauce see my Homemade Pizza Sauce recipe here. You could also use spaghetti sauce or marinara sauce.
