    If I want to do it on Saturday and bake it on Sunday, how is better to do it? Should I make the sauce and keep it in a fridge ?

      Hi Dana, you can completely prepare everything per instructions and just bake Sunday. You’ll just need to bake a little longer than indicated since it will be cold (since it was refrigerated). You’re going to love this recipe. 🙂

    Hi, this looks delicious! Just wondering if you have ever added al dente cooked pasta to the casserole before baking (like lasagna) to make it even more “make ahead”. Looks like there is plenty of sauce in the casserole to accommodate the pasta? Thanks!

    • admin 11/07/2017, 2:00 am

      Hi, Julie. I usually cook the pasta, drain it and close in Tupperware. Then just pour boiling water over the pasta before serving or heat in a skillet. Never thought of adding the pasta to the casserole but is a wonderful idea. Hhhmm. I’ll need to try that, or if you do before me, let me know how it turns out?.
      P.S. you need to try this asap – it’s phenomenal. 🙂 🙂
