Made this dish tonight for dinner. Cooked at 350°F for 1 1/2 hours and turned out perfectly. I used the whole envelope of dry onion soup mix and cream of celery soup. I think you could also use cream of chicken soup if you prefer. It's better to put all ingredients in first before chicken and mix them slightly then put chicken legs in and roll them to coat in the mixture. I also added a clove of garlic diced and sprinkled on top. Turned out very very well. A perfect amount of flavor, perfect consistency and the chicken was very moist. Would recommend for any potluck dinner.
