Ever since starting this blog and downsizing recipes to make for the two of us, I have been on the look out for dishes, pans, and gadgets that make cooking for two easy and convenient.

This week I bought new round 20-ounce oven-safe soup bowls which are the perfect size for these casseroles.

Can this Recipe be made in one 9”x9” baking dish? It really sounds delicious.

Can you make this ahead of time and freeze?

Zona

Hi Shirley, I have not tried freezing this casserole. I think, based on the ingredients and steps, that it should be ok to freeze before baking. I would also let it thaw overnight in the refrigerator before baking it in the oven for best results. If you decided to try it, let me know how it turns out for you :)

I can only find 17 ounce ramekins. Will that work for the Mexican casserole recipe ?

Hi Marcy, I think 17 oz would be fine. Just make sure they aren't over flowing when your adding the ingredients to them. Thanks for your question :)
