Frozen, cooked kale with added fat is a convenient, nutrient-dense staple, offering tender, earthy greens with a rich, savory mouthfeel. Its deep green color and mild, slightly sweet flavor make it a versatile base for countless dishes. Nutritionally, it packs a solid 2.85g of protein and 2.2g of fiber per 100g, all for just 66 calories.

↓ Full nutritionPeople love it for its hearty, satisfying texture that holds up well in soups, stews, and sautés, and for the convenience of having pre-cooked greens ready to use. It's a cornerstone of comfort foods from Southern U.S. cuisine to hearty European winter dishes.
The added fat increases calorie density, and kale contains oxalates which can inhibit mineral absorption. To counteract, pair it with a source of vitamin C (like lemon juice) to boost iron uptake, and enjoy it as part of a varied diet to manage oxalate intake. Those watching fat intake should compare brands, as added fat amounts can vary.
Kale is a cultivar of wild cabbage (Brassica oleracea) and is more closely related to Brussels sprouts and broccoli than it is to spinach.

How does freezing affect kale's nutrition?
Flash-freezing soon after harvest helps preserve most vitamins and minerals, particularly fat-soluble vitamins like A and K. The cooking process before freezing can reduce some heat-sensitive nutrients like vitamin C, but the overall nutritional profile remains very strong.
Why is fat added to frozen cooked kale?
Fat (often oil or butter) is added to improve flavor, mouthfeel, and to help the body absorb kale's fat-soluble vitamins (A, K, E). It also prevents the leaves from clumping together in the package.
Is the sugar content a concern?
No. The 1.09g of sugar per 100g is naturally occurring, minimal, and comes packaged with fiber and nutrients, so it does not cause blood sugar spikes like added sugars.
