Culinary Uses
Cruciferous vegetables add versatility to various dishes, from stir-fries to soups, salads, and roasted sides. Broccoli, kale, and Brussels sprouts are often roasted, sautéed, or steamed for flavor and texture.
Cooking Tips
Cruciferous vegetables are versatile in culinary preparations. To retain nutrients, steam or roast them briefly. Add a pinch of mustard powder to frozen varieties to activate sulforaphane. Sautéing with garlic enhances flavor. For tender results, avoid overcooking. Use fresh leaves in salads or blend into soups. Roasted Brussels sprouts and broccoli make delicious sides.
