What Is Canned Spinach?
Canned spinach is spinach that has been washed, cooked, processed, and sealed in airtight containers. The canning process helps preserve the vegetable for extended periods without refrigeration.

Many brands offer canned spinach in different varieties, including:

Because it has already been cooked, canned spinach has a softer texture and stronger flavor than fresh spinach.
