Creating Marry Me Chicken Pasta is straightforward if you follow these simple steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.
2. Prepare the Chicken: Season the chicken breasts with salt and pepper on both sides.
3. Sear the Chicken: In a large skillet, heat the 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. Make the Sauce: In the same skillet, add the minced garlic and sauté for 1 minute until fragrant. Pour in the heavy cream and bring to a simmer.
5. Add Flavor: Stir in the Italian seasoning, sun-dried tomatoes, and Parmesan cheese. Whisk until well combined and slightly thickened.
6. Combine Ingredients: Add the cooked pasta, spinach, and reserved pasta water to the sauce. Toss everything together until the pasta is well coated.
7. Slice the Chicken: While the pasta is absorbing the flavors, slice the chicken into strips.
8. Serve: Plate the pasta and top with the sliced chicken. Garnish with fresh basil and red pepper flakes if desired.

These steps will guide you to creating a meal that beautifully represents affection and culinary delight.
