FAQs
1. Can I make this casserole ahead of time?
Yes! You can prepare the casserole a day in advance. Just cover it and store it in the fridge until you’re ready to bake it.
2. What if I don’t have marinara sauce?
You can substitute marinara sauce with any pasta sauce or even homemade tomato sauce.
3. Can I use uncooked pasta?
It is best to use cooked pasta for this recipe. Uncooked pasta may not soften enough during baking and could result in a tough texture.
