01 - Preheat your oven to 475°F (245°C). If using a pizza stone, ensure it is placed in the oven during preheating to achieve optimal crispness.
02 - On a lightly floured surface, skillfully stretch or roll out the pizza dough to a 12-inch (30 cm) diameter circle. Transfer the prepared dough to a parchment-lined baking sheet or a pizza peel for easy handling.
03 - In a skillet positioned over medium heat, warm the olive oil. Add the minced garlic and sauté for approximately 30 seconds until fragrant. Introduce the shrimp to the skillet, season lightly with salt and black pepper, and cook just until the shrimp turn opaque and pink, which should take about 2-3 minutes. Remove the skillet from the heat.
04 - Generously spread the Alfredo sauce evenly across the pizza dough, maintaining a small border of about 1/2 inch around the edge. Following this, distribute half of the shredded mozzarella cheese over the sauce.
05 - Artfully arrange the seared shrimp and thinly sliced red onion over the cheese. If utilizing, sprinkle the crushed red pepper flakes evenly across the toppings.
06 - Add the remaining mozzarella cheese and all of the grated Parmesan cheese to complete the topping layers. Bake the pizza for 12-15 minutes, or until the crust achieves a golden brown hue and the cheese is wonderfully bubbly.
07 - Remove the pizza from the oven. Garnish generously with the chopped fresh parsley. Allow the pizza to cool slightly before slicing and serving to your guests.
