Creating Easy Pizza Pasta is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside.
2. Sauté Onions and Garlic: In the same pot, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until translucent. Stir in the minced garlic and cook for another minute until fragrant.
3. Add Tomatoes and Spices: Pour in the crushed tomatoes. Stir in the dried oregano, dried basil, red pepper flakes, salt, and pepper. Bring the mixture to a simmer, allowing the flavors to meld for about 5 minutes.
4. Combine Pasta and Sauce: Add the cooked penne pasta to the pot, mixing well to coat the pasta with the sauce.
5. Add Toppings: Fold in the pepperoni slices and half of the shredded mozzarella cheese, stirring until everything is evenly distributed.
6. Bake: Preheat your oven to 350°F (175°C). Transfer the pasta mixture to a baking dish and sprinkle the remaining mozzarella cheese over the top. Bake for 15-20 minutes until the cheese is bubbly and golden.
7. Garnish and Serve: Remove from the oven and let it cool for a few minutes. Garnish with fresh basil leaves before serving.
