Cut chicken into bite-sized pieces. Season with salt and pepper.
In a large skillet, melt 1 tablespoon of butter over medium-high heat. Add chicken and cook until golden and cooked through, about 5-7 minutes.
Remove chicken from the skillet. Add chicken broth and bring to a simmer. Add egg noodles, ensure they are covered, and cook until al dente, about 8-10 minutes.
Return chicken to skillet. Stir in remaining butter, garlic powder, peas, and season to taste. Cook until heated through.
Add fresh parsley, stirring to combine. Serve hot.
Notes
Store leftovers in an airtight container in the refrigerator for up to three days. Avoid freezing for best texture.
