FAQ

Can I make these ahead?

Toast bread and prepare spinach mixture separately up to 1 day ahead. Assemble and broil just before serving for best texture and melted cheese consistency.

What if I don't have a broiler?

Bake assembled crostini in a 400F oven for 5-7 minutes until cheese melts. Watch carefully to prevent burning.

Can I freeze these?

Freeze unbroiled assembled crostini on baking sheet, then transfer to freezer bag up to 1 month. Broil from frozen, adding 2-3 minutes to cooking time.
