Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Season the chicken pieces with salt, pepper, and Italian seasoning. Add the chicken to the skillet and cook until browned and cooked through, about 5-7 minutes. Remove from the skillet and set aside.
In the same skillet, add the minced garlic and sauté until fragrant, about 30 seconds. Add the roasted red peppers and cook for an additional 2 minutes.
Transfer the red pepper and garlic mixture to a blender, add the heavy cream, and blend until smooth. Pour the sauce back into the skillet over medium heat.
Stir in the grated Parmesan cheese and let the sauce simmer for 3-5 minutes until slightly thickened. Add the cooked chicken and pasta to the sauce, tossing to coat everything evenly.
Taste and adjust seasoning with salt and pepper if necessary. Cook for another minute to heat through.
Serve hot, garnished with fresh basil leaves on top.
