Beetroot leaves are nutritious and well-suited for making salads and other dishes. Beetroot leaves can be a substitute for lettuce or spinach leaves in recipes. Young beetroot greens are the best for salads since they are sweeter and more tender than older leaves. Older beatroot greens are often stir-fried, cooked, sautéed or steamed. Beetroot leaves have a somewhat bitter taste and are often combined with other ingredients in recipes.
