Thankfully, roasting solves both of these problems, intensifying the cruciferous vegetable's flavors and enhancing its texture with a delightful crunch. But if you are looking to turn an already irresistible side dish into a stand-out weeknight staple, try coating your broccoli in cornstarch before roasting to make it extra crispy. You might only associate cornstarch with thickening sauces or soups, but it also works great for crisping up just about any roasted vegetable.
