Creating your own Spicy Pierogi Pizza can be straightforward if you follow these simple steps:

1. Preheat your oven: Set your oven to 475°F (245°C) to ensure a crispy crust.
2. Prepare the pizza dough: Roll out your pizza dough on a floured surface to your desired thickness.
3. Pre-bake the crust: Place the rolled dough on a pizza stone or baking sheet. Bake for 5-7 minutes until it starts to firm up but is not yet browned.
4. Sauté the onions: In a skillet, heat olive oil over medium heat. Add the chopped onions and sauté until they’re translucent, about 3-4 minutes.
5. Combine the filling: In a bowl, mix ricotta cheese, sautéed onions, sauerkraut, crumbled bacon or sausage (if using), paprika, garlic powder, red pepper flakes, salt, and pepper until well combined.
6. Spread the filling: Remove the pre-baked pizza crust from the oven. Spread the filling evenly over the crust.
7. Add cheeses: Sprinkle shredded mozzarella cheese generously over the filling.
8. Finish baking: Return the pizza to the oven and bake for an additional 15-20 minutes, or until the cheese is bubbly and the crust is golden brown.
9. Cool down: Once baked, remove the pizza from the oven and let it cool for about 10-15 minutes.
10. Garnish: Before serving, sprinkle fresh parsley and chopped green onions on top for an extra pop of color and flavor.

These steps will guide you in creating this incredible pizza effortlessly.
