Storage
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, warm it in the oven at 350 degrees F until heated through, about 15-20 minutes.

FAQs
Can I use fresh green beans instead of frozen?
Yes, fresh green beans can be used. Steam or blanch them until tender-crisp before mixing with the other ingredients to ensure they cook evenly in the casserole.
Can I prepare the casserole ahead of time?
Absolutely. Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking. You may need to add a few extra minutes to the baking time if baking straight from the refrigerator.
