FAQ

Can I make this without an oven-safe skillet?

Transfer mixture to a greased baking dish after initial stovetop cooking, though texture may be slightly different.

What if I don't have fresh spinach?

Frozen spinach works well but thaw and drain excess water first to prevent a watery frittata.

How long will leftovers keep?

Refrigerate covered for up to 3 days and reheat gently in microwave or low oven.
