FAQs

Can I use frozen spinach instead of fresh?

Yes, you can substitute frozen spinach, but be sure to thaw and squeeze out excess moisture before adding to the casserole to avoid a watery dish.

Is it necessary to add pasta?

No, pasta is optional. The casserole works well as a protein and veggie dish on its own, but pasta adds extra heartiness if desired.
