You don’t have to travel to Chicago to eat doughy, cheesy deep dish pizza because now, you can make it right in your kitchen. The most time-consuming part of this recipe is making the dough, but you can prepare it up to a month in advance and freeze it for later. Bake the dough in a deep dish pan covered with homemade tomato sauce, sausage, and cheese until it’s golden-brown and bubbling.
For the pizza sauce, melt the butter in a small saucepan and add the onion, salt, red pepper flakes, and oregano, and sauté until golden brown. Add the garlic, sugar, and crushed tomatoes, and simmer for roughly 20 minutes or until sauce thickens. For the dough, combine the active dry yeast, sugar, and warm water together and let sit for one minute. In a large mixing bowl, combine the flour, cornmeal, and salt. Add the yeast mixture and butter into the dry ingredients and stir until dough forms. Bring dough to floured surface and knead until dough forms into a ball. Move dough to large bowl drizzled with olive oil. Coat dough in oil and cover. Let rest for 1 hour. Remove dough and bring onto floured surface. Cut dough in half and begin working dough out, ensuring that it is at least 2 inches (5 cm) wider than your deep dish pan. Double wrap the remaining dough with plastic wrap and place in a resealable freezer bag. Freeze for up to a month. Preheat your oven to 425°F (215°C). Bring your dough into your oiled and floured deep dish pan. Using your hands press dough into sides of your dish making it as even as possible. Lay slices of mozzarella across the dough, covering the entire bottom. Add pieces of uncased italian sausage on top of the mozzarella and top with tomato sauce. Bake for 20-25 minutes or until crust starts to lightly brown and the cheese is melted. Garnish with parmesan, cut and serve. Enjoy!
