FAQ

Can I use fresh spinach instead of frozen?

Yes, use 10 oz fresh spinach. Saute until wilted, then drain and squeeze out excess moisture before using.

What if I don't have an 11x7 dish?

Use any 2-quart baking dish. Adjust cooking time if depth changes significantly - deeper may need extra 5-10 minutes.

How long will leftovers keep?

Store covered in refrigerator up to 3 days. Reheat individual portions in microwave or whole dish in 350F oven.
