01 - Pat chicken breasts dry and season both sides generously with salt, pepper, garlic powder, and paprika, pressing the spices into the meat to adhere.
02 - Heat olive oil in a large, deep skillet over medium-high heat until shimmering. Add chicken breasts and sear for 3-4 minutes per side until deep golden brown. Transfer to a plate, leaving the fond in the pan.
03 - Add minced garlic to the hot pan and sauté for 30 seconds until fragrant, being careful not to burn. Pour in chicken broth and bring to a boil, scraping up the browned bits from the bottom with a wooden spoon.
04 - Add egg noodles to the boiling broth, stirring to submerge. Nestle seared chicken breasts on top of the noodles. 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 165°F internally.
05 - Remove cooked chicken to a cutting board. Stir butter, parsley, and Parmesan into the noodles until melted and glossy. Slice chicken or serve whole over noodles, garnished with additional fresh parsley.
