In a large skillet, heat olive oil over medium-high heat. Add the cubed chicken breast, seasoning with salt and pepper. Cook for about 5-7 minutes until browned and cooked through, then remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the chicken broth and bring it to a simmer. Add the broccoli florets and cook for about 3-4 minutes until they are tender but still vibrant green.
Stir in the heavy cream and Italian seasoning, allowing it to heat through.
Meanwhile, cook the pasta according to package instructions in a separate pot, then drain.
Add the cooked pasta to the skillet along with the cooked chicken. Mix everything together until well combined.
Gradually stir in the grated Parmesan cheese until melted and creamy. Adjust seasoning with salt and pepper if necessary.
Remove from heat and let it sit for a couple of minutes to thicken slightly.
Notes
Serve hot in bowls, garnished with freshly chopped parsley and an extra sprinkle of Parmesan on top for an appealing look.
