Yes, broccoli leaves, stems, and stalks are totally edible, both raw and cooked! The leaves are loaded with calcium, Vitamin E, Vitamin K, and antioxidants. You can use them the same way you would kale or spinach. While they're edible raw, they taste better cooked. Most folks opt for broccoli florets for their vibrant color, texture, and taste. However, the stems beat the florets in nutrition by a long shot. The stalks are pretty firm, even peeled, and add a lovely crunch to any dish.
