Start by boiling a large pot of water with a generous pinch of salt. Cook the pasta until it’s al dente—just tender but still with a little bite. This helps it hold up better when coated in sauce. Drain and set aside while you prep everything else.
In your sauté pan, heat olive oil over medium heat. Add the diced chicken, season with salt and pepper, and cook for about 6–7 minutes until golden and fully cooked. Stir occasionally to get even browning. Once done, remove the chicken and set it aside.
In the same pan, add a little more oil if needed and toss in the minced garlic. Stir constantly for 1–2 minutes until the garlic smells amazing but isn’t browned. Burnt garlic will make the sauce bitter, so watch it closely.
Pour in the chicken broth and cream, then stir everything to combine. Let it simmer on low heat for a few minutes. Add Parmesan cheese, Italian seasoning, salt, and pepper. Stir often until the cheese melts and the sauce thickens up a bit.
Return the cooked chicken to the pan. Stir it into the sauce and let the flavors combine. Now add the drained pasta and toss everything together until well-coated. If you’re adding spinach or sun-dried tomatoes, now’s the time. Let them heat through for a minute or two.
Plate your creamy chicken pasta while it’s hot! I like to sprinkle a bit of extra Parmesan and a little cracked pepper on top. It looks fancy but takes almost no extra effort.
