FAQ

Can I freeze stuffed shells?

Yes, assemble without baking, cover tightly and freeze up to 3 months. Bake from frozen, adding 10-15 extra minutes.

What if my shells split while cooking?

Use split shells anyway - they'll still hold filling and taste great. Cook future batches 1-2 minutes less.

Can I use different vegetables?

Absolutely. Try mushrooms, zucchini, or spinach. Saute until tender and drain excess moisture before mixing.
