Baked Penne Vodka Pasta

2 Preheat your oven to 375°F (190°C).
4 Boil the penne pasta in a large pot of salted water until just al dente. Drain and set aside.
6 In a large skillet, heat olive oil over medium heat. Add the finely chopped onion and sauté until it becomes translucent. Add minced garlic and continue cooking until fragrant.
8 Pour in the vodka and let it simmer for a couple of minutes, allowing the alcohol to evaporate and leaving behind a rich flavor.
10 Stir in the tomato paste, ensuring it's well incorporated into the onion and garlic mixture. Cook for 2-3 minutes, allowing the tomato paste to caramelize slightly.
12 Pour in the heavy cream. Season with Italian seasoning, salt and pepper to taste. Add the Parmesan cheese, stirring constantly to create a creamy and luscious sauce. 
14 Mix the cooked penne into the vodka sauce, ensuring every piece is coated evenly.
16 Transfer the vodka pasta to a large baking dish. Top it with more parmesan cheeseI and fresh mozzarella slices. 
18 Bake in the preheated oven for 25-30 minutes or until the cheese is golden and bubbly.
20 Remove the baked penne vodka pasta from the oven, garnish with fresh basil, and let it cool for a few minutes before serving.
