    Hi,
    Can you use Orzo?
    Thanks!

    1. Lynette Rice says:

      I’ve never tried the orzo with this recipe. I can’t recommend it.

  2. Maryann Stevens says:

    Good recipe, but needs to be doubled. It doesn’t make much with one cup of rice.

    1. Hi Maryann, thanks for the feedback. I’ll test the recipe again to see how we can make it better.

  3. Lisa DeLuca says:

    can I use frozen spinach instead of fresh?

    1. Yes. I would make sure it’s fully thawed. After thawed, squeeze out as much moisture as possible.

  4. How long will it last in the freezer?

  5. Did you defrost it before baking or did you just pop it into the oven frozen (and adjust the cooking time)?

    1. Hi Rebecca. Yes, I did defrost it before baking it.

  6. This sounds great! For the one you are freezing, are you baking it first? Thanks!

    1. Hi Cynthia. I did not bake it first and it was great!
