FAQs
Can I use a different type of pasta?
Absolutely! While mostaccioli is great for this recipe, you can use other tubular pasta like penne, rigatoni, or ziti. Just ensure you cook it al dente to avoid mushy pasta after baking.
What can I use as a dairy-free alternative for the cheese?
You can substitute dairy-free mozzarella and Parmesan alternatives. There are many vegan cheese options available that would work well in this dish.

hey, can I skip the veggies or nah? not a big fan lol
Why would you wanna skip the best part? Veggies add so much flavor and color!
just tried makin this but burnt it, oven temps are tricky huh
Adding all these veggies and then baking it? Seems like a mush fest to me. Sandra, ever thought of something less watery?
Actually, if you sauté them right, they come out perfect even after baking!
if you cook pasta in wine instead of water does it become a dessert asking for a friend
Loved this recipe Sandra! Tried it with the kids and even they ate the veggies, miracles do happen!
