Can You Freeze Kale?

Can you freeze kale?

Yes, kale freezes well after blanching. Like other dark leafy greens, kale contains active enzymes that continue to degrade the leaves at freezer temperatures without blanching; this causes color fading, bitter flavor development, and texture decline. Blanching deactivates these enzymes, preserving the kale in its best state. All varieties of kale freeze well: curly kale (the most common); lacinato/dinosaur kale (Tuscan kale, flatter leaves); red Russian kale; baby kale; ornamental kale (decorative, less commonly eaten); kale rabe; cavolo nero. Frozen blanched kale lasts 8-12 months for best quality at 0°F (-18°C); safe indefinitely. After thawing: kale becomes softer than fresh (it's already been wilted by blanching); the bright green color is preserved; the flavor remains good. Don't freeze raw kale - the texture deteriorates significantly within weeks. Frozen kale is ideal for cooked applications and smoothies but not for fresh salads or massaged kale dishes.

How do you blanch and freeze kale?

Standard blanching process for kale. Step 1: prepare kale. Wash thoroughly to remove sand or grit; remove tough center stems (use a knife or strip by hand); tear or chop into bite-sized pieces. Step 2: blanch. Bring a large pot of water to a boil; prepare an ice bath; submerge kale 2-3 minutes (less for baby kale); the leaves should wilt and turn bright green. Step 3: ice bath. Transfer kale immediately to ice water; cool for 2-3 minutes. Step 4: squeeze out water. This is critical for kale - squeeze as much water as possible from the leaves; the kale will compress into small balls; prevents excessive ice and dilution of dishes. Step 5: portion and freeze. Form into small balls (1/2 cup or 1 cup balls); wrap individually or place in freezer bags; freeze.

How do you use frozen kale?

Frozen kale is best used directly from frozen in cooking. Direct from frozen (best method): add frozen kale balls or chopped pieces directly to soups, stews, curries, casseroles; the kale thaws and incorporates with cooking liquid. For smoothies: add frozen kale directly to blender with fruits, yogurt, milk; blends easily. For sautéed kale: add frozen kale to hot oil with garlic; cook 5-7 minutes until heated through and softened further. For pasta dishes: add frozen kale to pasta water during last 2 minutes of cooking; drain together with pasta. For Italian wedding soup or minestrone: add frozen kale directly. For kale and white bean stew: drop frozen kale into stew during last 10-15 minutes. Don't expect to use frozen-thawed kale for: massaged kale salads (texture is too soft); kale chips (too watery for crisping); fresh kale wraps; raw kale slaws. The frozen-thawed kale works for any cooked application.

How long does frozen kale last?

Kale in cooked dishes (soup, stew already made): 4-6 months. Kale pesto (with oil and cheese): 4-6 months. All safe indefinitely at 0°F. Signs of quality issues: yellow or brown color (enzyme damage); bitter taste beyond normal; mushy texture upon thawing; significant freezer burn; ice crystal buildup.
