01 - Season chicken breasts thoroughly with kosher salt, freshly ground black pepper, garlic powder, and paprika on both sides.
02 - Heat olive oil in a large deep skillet over medium-high heat. Add chicken breasts and sear for 3-4 minutes per side until golden brown. Remove chicken to a plate and set aside.
03 - Add minced garlic to the same pan and sauté for 30 seconds until fragrant.
04 - Pour in chicken broth and bring to a boil, scraping up browned bits from the bottom of the pan.
05 - Add egg noodles to the pan, stirring to submerge. Nestle seared chicken breasts on top. Reduce heat to medium-low, cover, and simmer for 12-15 minutes, stirring noodles once or twice to prevent sticking, until noodles are tender and chicken reaches internal temperature of 165°F.
06 - Remove cooked chicken and set aside. Stir butter, parsley, and Parmesan cheese (if using) into noodles until melted and glossy.
07 - Slice or serve chicken breasts whole over the buttered noodles, garnished with additional fresh parsley.
