FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a day before baking. Keep it covered in the refrigerator and bake just before serving, adding extra bake time if baking straight from cold.
Can I use a different type of pasta?
Absolutely. While spaghetti works well, you can substitute with penne, rotini, or other pasta shapes you have on hand.
