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 sugar. Stir gently and let sit for 5 minutes until foamy to proof the yeast.
2. Step 2: In a large mixing bowl, whisk together 3 cups all-purpose flour and 1 tsp salt. Add the yeast mixture and 1/4 cup olive oil, stirring with a wooden spoon until a shaggy dough forms.
3. Step 3: Turn the dough onto a lightly floured surface and knead for 7-8 minutes until smooth and elastic. Place the dough in a lightly oiled bowl, cover with a damp towel, and let rise in a warm place for 1 hour until doubled in size.
4. Step 4: While the dough rises, heat a large skillet over medium heat and add 12 oz Italian sausage, breaking it up with a spoon. Cook for 5-6 minutes until browned and cooked through, then transfer to a paper towel-lined plate.
5. Step 5: In the same skillet, add the thinly sliced 1 medium yellow onion and cook over medium-low heat for 12-15 minutes, stirring occasionally, until golden and caramelized.
6. Step 6: Preheat the oven to 425°F. Punch down the dough and press it into a 12-inch deep-dish pizza pan, making sure to cover the bottom and sides evenly.
7. Step 7: Spread 2 cups crushed tomatoes evenly over the dough, then sprinkle with 3 minced garlic cloves, 1 tsp dried oregano, and 1/4 tsp red pepper flakes. Add the cooked sausage and caramelized onions evenly over the sauce.
8. Step 8: Generously top with 3 cups shredded mozzarella cheese, then sprinkle 1/4 cup grated Parmesan cheese over the top.
9. Step 9: Bake the pizza in the preheated oven for 25-30 minutes until the crust is golden and cheese is bubbly and lightly browned. Let rest 5 minutes before slicing and serving.
