Spare Spoons Kitchen
A pantry side from a can — layers of asparagus and crushed saltines bound in cream of celery soup, topped with cheese and baked. Old-fashioned, fast, and comforting.
Save the asparagus liquid — it's what thins the condensed soup into a sauce; without it the casserole is too stiff.
Vegetarian as written (cream of celery has no meat — check the label).
A handful of toasted slivered almonds in the layers is a classic addition.
Fresh or frozen asparagus works too — blanch briefly and use a splash of broth or milk in place of the canning liquid.
Gluten-free: use gluten-free crackers and a gluten-free cream of celery soup.
Vegetarian: it already is — just confirm the soup brand.
