Cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the sliced chicken breasts and season with salt, pepper, and Italian seasoning. Sauté until the chicken is cooked through and golden brown (about 5-7 minutes).
Add the minced garlic to the skillet and cook for an additional minute until fragrant.
Pour in the chicken broth and bring to a simmer. Let it cook for about 3-4 minutes to reduce slightly.
Stir in the heavy cream and bring the mixture back to a gentle simmer.
Add the halved cherry tomatoes and fresh spinach. Cook until the spinach is wilted and the tomatoes are softened, about 2-3 minutes.
Stir in the cooked penne and grated Parmesan cheese. Toss everything together until well combined and the pasta is coated in the creamy sauce.
Taste and adjust seasoning with more salt and pepper if needed.
Serve hot, garnished with fresh basil leaves on top.
