The Secret to Perfectly Roasted Vegetables

Roasting vegetables may sound simple, but a few small details make all the difference. First, don’t overcrowd the pan. Vegetables need space to roast rather than steam, so spread them out evenly. Second, high heat is key. A hot oven ensures caramelization, which creates those deep, savory flavors that make this bake irresistible.

Finally, seasoning before roasting allows the vegetables to absorb flavor while cooking. The cheese finishes the dish, but the vegetables themselves should already taste amazing.

Fun Food Fact

Roasting vegetables dates back centuries and was originally used as a way to preserve flavor without added sauces.
