Cut the chicken into bite-sized pieces and season with garlic powder, onion powder, salt, and pepper. Heat olive oil in a large skillet over medium heat and cook the chicken for 5-7 minutes until browned and cooked through.
Bring a pot of salted water to a boil, add the egg noodles, and cook according to package instructions for 7-9 minutes. Drain and set aside.
Pour in the chicken broth and bring to a gentle simmer. Cook for 2-3 minutes, then stir in the heavy cream and frozen peas. Cook for an additional 3-4 minutes until heated through and slightly thickened.
Add the cooked egg noodles to the skillet with the creamy sauce. Toss gently to coat the noodles, then stir in the grated Parmesan cheese until melted.
Garnish with fresh parsley and serve.
