Creating this Creamy Pasta Bake with Cherry Tomatoes and Basil is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Pasta: In a large pot, boil salted water and cook the penne pasta until al dente. Drain and set aside.
3. Sauté Garlic and Tomatoes: In a large skillet, heat a drizzle of olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Add the halved cherry tomatoes and cook for 5 minutes until they begin to soften.
4. Prepare Cream Sauce: In the same skillet, pour in the heavy cream. Stir in the Italian seasoning, red pepper flakes (if using), salt, and pepper. Allow the mixture to simmer for 2-3 minutes.
5. Combine Pasta and Sauce: Add the cooked penne pasta to the skillet, stirring until the pasta is well coated in the creamy sauce.
6. Add Cheese and Basil: Stir in the shredded mozzarella cheese, grated Parmesan cheese, and chopped basil. Mix until the cheese is melted and everything is well combined.
7. Transfer to Baking Dish: Pour the pasta mixture into a greased 9×13 inch baking dish. Spread it evenly.
8. Top with Cheese: Sprinkle additional mozzarella cheese on top for a cheesy crust.
9. Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden and bubbly.
10. Garnish: Once out of the oven, let it cool for a few minutes. Garnish with additional fresh basil before serving.
