In a large pot, boil salted water and cook your pasta according to package instructions.

While the pasta cooks, heat olive oil in a skillet over medium heat.

Add the sliced chicken breast to the skillet and season with salt, pepper, and Italian seasoning.

Once the chicken is cooked through, stir in the minced garlic and red pepper flakes.

Add the chicken broth to the skillet, scraping up any browned bits from the bottom.

Reduce the heat to low and pour in the heavy cream, stirring to combine.

Gradually add the grated Parmesan cheese, stirring until melted and smooth.

Drain the pasta and add it to the skillet along with the chopped spinach.

Toss everything together until well coated and the spinach wilts.
