I like to start the sauce first, so it has some extra time to simmer and blend flavors while I make the dough. This is the same sauce I use on my basic homemade pizza. It will make enough to have inside the strombolis and to use for dipping or spreading on top.
Makes 2 large strombolis.
Homemade Pizza Sauce
1 can tomato paste
1/2 cup water
2 Tbsp olive oil
1/4 tsp salt
1/8 tsp ground pepper
1/2 tsp oregano
1/2 tsp basil
1/2 tsp garlic powder
Add all ingredients to saucepan and stir well. Bring to a simmer on medium high, then reduce to low and cover, stirring frequently.
Next, make the dough. This is also the basic recipe I use for my homemade pizza. It is easy and versatile.
Homemade Pizza Dough
2 1/2 cups flour
1 packet active dry yeast
1/2 tsp salt
2 Tbsp olive oil
1 cup warm water
Note: I use a stand mixer that with a dough hook attachment to save some of the work of kneading, since I get inflammation easily in my hands. I’ll provide the information for making it either using the stand mixer to knead or by hand.
Preheat oven to 425. In a large mixing bowl (or the bowl from your stand mixer), combine 1 cup flour with the yeast and salt. Add in warm water and oil. Beat with mixer on low speed for 30 seconds, then on med high for 3 minutes. Scrape bowl with spoon as needed.
Kneading by hand: Using a wooden spoon, stir in as much of the remaining flour as you can. Turn dough out onto a lightly floured surface. Continue to knead in flour until dough is smooth, elastic and not sticky (around 5 minutes).
Kneading using mixer: Slowly add remaining flour, 1/2 cup at a time and continue to mix on medium for 3 minutes, until no more flour will go into dough. Remove dough from bowl, turn onto lightly floured surface and knead in enough remaining flour to make a moderately stiff but elastic dough.
Take one of the balls of dough and flatten it out into a wide rectangular shape on a lightly greased pan. You can do this by hand or use a rolling pin to flatten it to around 1/4 inch thick. Poke holes in dough with a fork. Repeat with the second ball.
Loaded Stromboli Filling
1/2 cup cooked sausage
1/2 cup chopped bell pepper
1/3 cup sliced black olives
1 cup shredded mozzarella cheese
1/4 cup grated parmesan cheese
Brown sausage in pan and crumble. Spread a thin layer of sauce on half of each rectangle of dough. Sprinkle a layer of sausage and veggies evenly over the sauce. Top with cheeses. Leave at least 1/2 inch dough plain around the outer edges.
Cook for 20-25 minutes, or when beginning to get golden brown on edges and top. Remove from oven and serve warm with extra sauce spread on top or in a bowl on the side for dipping.
