Hello. I am hosting a party this Sunday. I have two 9 x 12s with enchiladas and two 9 x 12s with salsa verde chicken casserole. All of them are frozen in metal pans. The salsa verde dish is corn tortillas, cheese, salsa verde, cream, onions, and chicken. The salsa verde is a heavier dish than the enchildas. All were baked before freezing. How long do I cook them? All four will be in the oven at the same time. Party starts at noon, want to serve at 12:30. Oven is electric. I've been advised not to thaw the enchiladas due to the risk of the corn tortillas becoming soggy if I do. I want to cook from frozen, no thawing. Oh and I have Salton hot plates to keep them warm after baking. Any advice much appreciated.
