Step 1

Melt butter in a large skillet over medium heat. Add chicken and cook until very lightly browned on both sides but not cooked through.

Step 2

Add chicken broth to skillet and reduce heat to low. Simmer for about 10 minutes or until the chicken is cooked through. Remove chicken from the skillet and place on a plate.

Step 3

Leaving chicken broth in the skillet, add sour cream, garlic powder, salt, and pepper. While still cooking on low, stir until sour cream is melted and fully incorporated.

Step 4

Remove about 1/2 cup of liquid and stir flour into it until smooth. Pour back into the skillet and stir with a wire whisk until the gravy thickens and is smooth again.

Step 5

Add chicken back and turn to coat. Serve chicken and sauce immediately over egg noodles.
