Creating Marry Me Chicken Pasta is simple and straightforward. Follow these steps to ensure a delightful meal:

1. Cook Pasta: In a large pot of boiling salted water, cook the penne pasta according to package instructions until al dente. Drain and set aside.
2. Season Chicken: While the pasta cooks, sprinkle both sides of the chicken breasts with salt and black pepper.
3. Heat Olive Oil: In a large skillet over medium-high heat, add the olive oil. Once hot, add the seasoned chicken breasts.
4. Sear Chicken: Cook the chicken for about 5–7 minutes on each side or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
5. Sauté Garlic: In the same skillet, reduce the heat to medium and add the minced garlic and red pepper flakes (if using). Sauté for 1 minute, or until fragrant.
6. Add Cream and Broth: Pour in the heavy cream and chicken broth, stirring to combine. Let it simmer for about 2-3 minutes.
7. Incorporate Tomatoes: Add in the diced tomatoes and Italian seasoning. Stir to mix well, allowing the sauce to reduce slightly for about another 3-5 minutes.
8. Add Parmesan: Stir in the grated Parmesan cheese until melted and the sauce is creamy.
9. Combine Ingredients: Slice the cooked chicken into strips and return it to the skillet. Add the drained pasta, tossing everything together until well combined.
10. Taste and Adjust: Taste the dish and adjust the seasoning with more salt and pepper, if needed.

At this point, your Marry Me Chicken Pasta should be almost ready to serve!
