In a large skillet, sauté mushrooms and onions in cooking spray until slightly brown and soft, about 5 minutes.
Add ground turkey and cook until turkey is crumbled and brown, about 5-7 minutes. Add garlic, flour, paprika, thyme, salt, and pepper stir to combine for about a minute.
Add Worcestershire sauce, chicken stock, and egg noodles to the pan. Gently mix together until egg noodles are submerged in the liquid.
Bring to a boil, then cover and lower the heat to a simmer. Cook for about 15 minutes, or until noodles are tender.
Turn heat to low and gently stir in cream cheese and sour cream. Continue to stir until cream cheese is completely melted. Allow the stroganoff to sit for a few minutes to thicken.
