Making Penne Rosa is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot, boil salted water and cook the penne pasta according to package instructions until al dente. Drain and set aside.

2. Sauté the Onion and Garlic: In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute.

3. Make the Sauce: Pour in the crushed tomatoes and stir to combine. Add the heavy cream, Italian seasoning, and red pepper flakes (if using). Stir well and let simmer for 5-7 minutes until the sauce thickens slightly.

4. Combine Pasta and Sauce: Stir in the cooked penne pasta and mix until the pasta is well coated with the sauce. Season with salt and pepper to taste.

5. Add Cheese: Right before serving, sprinkle in the grated Parmesan cheese and mix until melted and creamy.

6. Garnish and Serve: Remove from heat, garnish with fresh basil leaves, and enjoy your amazing Penne Rosa!
