Can You Freeze Chopped Spinach (Raw)?

Spinach's leaves collapse dramatically once frozen and thawed — a bag of raw spinach that looked like a generous handful going into the freezer comes back out as a small, dense clump, which is worth planning for if a recipe is measuring spinach by volume rather than weight. Blanching first isn't just about color; it also shrinks the spinach down before freezing, so what you're portioning into the freezer more closely matches what you'll actually be adding to a dish later rather than measuring raw volume that's about to shrink further anyway. Frozen spinach works directly in a hot pan, soup, or smoothie without needing to thaw first, since its collapsed texture cooks through in moments.

Spinning washed spinach dry in a salad spinner and patting it with a towel before freezing removes far more surface water than air-drying alone, and that matters specifically for the freezer, since any leftover water forms extra ice crystals that add to the already dramatic volume collapse spinach goes through when frozen.

Baby spinach and mature spinach behave slightly differently when frozen — baby spinach's more tender leaves collapse a bit more completely than mature spinach's sturdier leaves do, which is worth knowing if a recipe's texture matters, though both varieties need the same blanching step and both work fine in a cooked application either way.

A food scale is genuinely useful when portioning spinach for the freezer, since its dramatic volume collapse after blanching makes measuring by cups before freezing a poor predictor of how much will actually be in a bag once it's thawed and ready to use in a recipe.
