FAQs
Can I make this casserole ahead of time?
Yes, you can! Prepare the casserole up to the point of baking. Cover it tightly with plastic wrap or aluminum foil and store it in the refrigerator for up to 24 hours. When you’re ready to serve, bake it as directed, adding an extra 5-10 minutes to the baking time if needed.
What can I use if I don’t have rigatoni pasta?
If you don’t have rigatoni, you can use other pasta shapes like penne, ziti, or even macaroni. Just make sure to cook the pasta until al dente, as this will help it hold up well during baking.

Sandra, don’t you think all that cheese and meat is a bit much? What about a veggie version?

Would this casserole have pleased the emperors of Rome, I wonder.
Actually, browning the meat before adding it to the casserole is crucial for texture. Don’t skip!
seems cool but too much work maybe lol
Another casserole? Revolutionary, Sandra. Really breaking new ground here.

Doesn’t sound like real Italian food to me. Doubtful it tastes good.
