Collard greens are large, dark green leaves from the cabbage family, known for their robust, slightly earthy flavor and a texture that turns silky and tender when cooked. This preparation—steamed or boiled without added fat—highlights their natural, mild bitterness and deep, savory notes. Nutritionally, they are a low-calorie powerhouse, packing over 4 grams of fiber and a solid protein boost into every 100-gram serving.

↓ Full nutritionPeople cherish collards for their hearty, soulful flavor that forms the backbone of comforting slow-cooked dishes. Their leaves are incredibly versatile, able to be braised, steamed, or chopped into soups, absorbing seasonings beautifully while retaining a satisfying bite.
The natural bitterness and potential toughness can be off-putting if undercooked. Those sensitive to oxalates, which can contribute to kidney stones, should be mindful of portion size. To counteract bitterness, a long, slow cook with a splash of acid like vinegar or lemon juice at the end can brighten the flavor. To reduce oxalates, blanching the collards in a large pot of water and discarding the water before final cooking is effective.
Collard greens are a member of the same plant species as cabbage, broccoli, and kale (Brassica oleracea), making them all cultivars of the exact same plant.

How do I remove the tough center stem from collard leaves?
Fold the leaf in half lengthwise along the stem. Hold the base of the stem with one hand and use your other hand to pull the leafy part away from the stem in a firm, continuous motion.
Why are my collard greens still tough after cooking?
They likely need more time. Collards are a sturdy green and typically require 45 minutes to 1.5 hours of simmering or braising to become fully tender and silky.
Can I eat collard greens raw?
Yes, but they are very tough. To use them raw in salads, very thinly slice or 'massage' the chopped leaves with a bit of acid (like lemon juice) and salt to soften them.
