Do you need to cook a casserole with raw eggs before you freeze it? I made a casserole yesterday that contains cooked pasta, cooked quinoa, dairy products, spinach and raw eggs. It is assembled and the baked at 350 for 30 minutes.

I am planning on making it again this weekend to freeze. Since the only raw ingredient is the eggs would it be okay to assemble it then freeze and cook the eggs when I am thawing it or should I cook it both now and after I bring it out of the freezer?
This is absolutely fine, especially if the eggs are pasteurised. I've seen plenty of recipes that have raw egg in them that say it;s fine to freeze them. You can even freeze eggs (that have been mixed up a little) for up to three months. So yes, I'd say freeze it as soon as possible. Also, if you were concerned about freezing the quinoa that will fine as well (a lot of people don't know you can store grains in the freezer). 

Enjoy!
