Creating the delicious Marry Me Chicken Pasta is simple when you follow these steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.
2. Season the Chicken: While the pasta cooks, season the chicken breasts with salt and pepper on both sides.
3. Sear the Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and cook for about 6-7 minutes per side until golden brown and cooked through. Remove from the skillet and set aside.
4. Sauté the Garlic: In the same skillet, add minced garlic and sauté for about 1 minute until fragrant.
5. Make the Sauce: Pour in the heavy cream and chicken broth. Stir in Italian seasoning and red pepper flakes if using. Bring to a simmer.
6. Add Cheese: Stir in the grated Parmesan cheese until melted and the sauce thickens slightly.
7. Combine Ingredients: Slice the cooked chicken and return it to the skillet. Add the drained fettuccine, tossing to coat everything in the creamy sauce.
8. Serve: Cook for an additional 2-3 minutes to heat through, then remove from heat.
