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 chicken pieces, garlic powder, onion powder, salt, and pepper. Cook until the chicken is browned and cooked through, about 5-7 minutes.
Reduce the heat to low and pour in the heavy cream. Stir to combine.
Add the grated Parmesan cheese and stir until melted and smooth.
Stir in the frozen peas and Italian seasoning, cooking for an additional 2-3 minutes until the peas are heated through.
Add the cooked penne pasta to the skillet and toss to coat in the creamy sauce.
Serve immediately, garnished with fresh parsley.
