Frozen spinach is typically sold either as chopped spinach or as cut-leaf (already cut) spinach, with both forms commonly available in retail frozen-food sections.
Some frozen spinach products are blanched before freezing, while others are fully cooked and packaged ready-to-heat. The preparation method depends on the product and brand.
Steam-in-bag spinach is microwavable. Typical instructions: leave the bag sealed, place it in the microwave with the side labeled "THIS SIDE UP" facing up, heat (example: about 6 minutes on high), let the bag stand for 1 minute, then open carefully to avoid steam.
Packaging often highlights vitamins and minerals and low calories. Examples include claims such as an excellent source of vitamin A, a good source of magnesium (about 10% DV per serving), and roughly 30 calories per serving.
Labels observed include non-GMO claims and USDA Organic certification on some items; some packages also note SNAP & EBT eligibility. Specific certifications vary by product.
