Cook the egg noodles according to package instructions, then drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes.
Stir in the minced garlic and sliced mushrooms, cooking for an additional 5 minutes until the mushrooms are tender.
Push the vegetables to one side of the skillet and add the sliced turkey breast to the other side. Cook until the turkey is browned and cooked through, approximately 6-8 minutes.
Sprinkle the flour and paprika over the turkey and veggies. Stir well to combine, then gradually pour in the chicken broth, stirring constantly to avoid lumps.
Bring the mixture to a gentle simmer and cook for 5 minutes until slightly thickened.
Remove the skillet from heat and stir in the sour cream until smooth. Season with salt and pepper to taste.
Fold the cooked egg noodles into the creamy turkey mixture until combined.
Notes
Serve in deep bowls, garnished with fresh parsley. Pair with steamed vegetables for a complete meal.
