Instructions

1. Step 1: In a small bowl, combine 1 cup warm water (110°F), 2 1/4 tsp active dry yeast, and 1 tbsp granulated sugar. Stir gently and let sit for 5-7 minutes until foamy.
2. Step 2: In a large mixing bowl, whisk together 3 cups all-purpose flour and 1 1/2 tsp salt. Pour in yeast mixture and 1/4 cup olive oil, stirring with a wooden spoon until dough forms.
3. Step 3: Knead dough on a floured surface for 8-10 minutes until smooth and elastic. Place in a lightly oiled bowl, cover with a clean towel, and let rise in a warm spot for 1 hour until doubled.
4. Step 4: While dough rises, heat 2 tbsp olive oil in a large skillet over medium heat. Add 12 oz raw Italian sausage, breaking it up with a spoon; cook for 6-7 minutes until browned and cooked through. Remove to a plate.
5. Step 5: In the same skillet, add sliced large yellow onion and sauté over medium heat for 10 minutes until soft and golden. Add 3 minced garlic cloves and cook for 1 minute until fragrant.
6. Step 6: Add 28 oz crushed tomatoes, 1 tsp dried oregano, and 1 tsp dried basil to the skillet with onions and garlic. Simmer over low heat for 20 minutes until sauce thickens, stirring occasionally.
7. Step 7: Preheat oven to 425°F. Press risen dough into a well-oiled 12-inch deep-dish pizza pan, pushing dough up the sides to form a thick crust.
8. Step 8: Layer 3 cups shredded mozzarella evenly over the dough, then spread cooked sausage over the cheese.
9. Step 9: Spoon the tomato sauce with onions evenly on top of the sausage layer. Sprinkle 1/2 cup grated Parmesan cheese over the sauce.
10. Step 10: Bake pizza in the preheated oven for 30-35 minutes until crust is golden and cheese is bubbly. Let cool 10 minutes before slicing.
