In a small bowl, combine warm water, sugar, and active dry yeast. Allow the mixture to rest until it becomes foamy, 5 to 10 minutes.
02 -
In a large bowl, blend all-purpose flour, cornmeal, and salt. Incorporate the yeast mixture, melted unsalted butter, and olive oil. Mix until a shaggy dough forms.

Transfer dough to a lightly floured surface. Knead until smooth and elastic, about 5-7 minutes. Move to an oiled bowl, cover, and let rise at room temperature until doubled in size, approximately 1 to 2 hours.

Heat olive oil in a saucepan over medium heat. Sauté finely chopped onion for about 5 minutes until translucent. Add minced garlic and cook until fragrant, about 1 minute. Stir in crushed tomatoes, oregano, basil, sugar, salt, and black pepper. Simmer gently for 20-30 minutes, stirring occasionally.

Preheat oven to 425°F. Roll the risen dough into a 12-inch circle. Grease a deep-dish pizza pan and press the dough evenly into the base and sides to form a thick crust.
06 -
Arrange mozzarella cheese slices evenly over the base. Distribute cooked and crumbled Italian sausage, pepperoni slices, chopped spinach, and sliced mushrooms as desired.
07 -
Spoon the prepared tomato sauce over the toppings, spreading to cover the filling completely. Sprinkle grated Parmesan cheese evenly over the sauce.
08 -
Bake in the preheated oven for 30-35 minutes, until the crust is golden and the sauce bubbles. Cover the outer crust edges with foil if they brown too quickly.

Allow to cool for several minutes before slicing. Serve hot.
