Heat a large skillet over medium-high heat. Season chicken breasts with salt, pepper, and Italian seasoning. Add olive oil to the skillet and sear the chicken for 4-5 minutes per side until golden brown. Remove and set aside.
Prepare the Sauce
In the same skillet, sauté garlic for about 30 seconds until fragrant. Add chicken broth, heavy cream, and Parmesan cheese. Whisk until smooth and creamy. Stir in sun-dried tomatoes and red pepper flakes.
Cook the Pasta
Meanwhile, cook pasta in salted water according to package instructions until al dente. Reserve 1 cup of pasta water before draining.
Combine and Simmer
Return the chicken to the skillet and let it simmer in the sauce for about 10 minutes, or until fully cooked. Toss in the cooked pasta, adding reserved pasta water as needed to achieve desired sauce consistency.
Serve and Enjoy
Plate the pasta, garnish with extra Parmesan and parsley if desired, and serve immediately.
Notes
Use freshly grated Parmesan for the best flavor and creaminess.
Adjust the red pepper flakes to your spice preference or omit if desired.
For leftovers, store in an airtight container in the fridge for up to 3 days and reheat with a splash of cream or chicken broth.
