How to Roast Summer Vegetables

We’ve listed the most common summer vegetables here along with instructions for how to roast them and their approximate cooking times. You can season these vegetables with salt and pepper alone, or use our suggested additions to fancy things up a little.

All of these veggies should be roasted on rimmed baking sheets. We like to coat them with non-stick cooking spray or olive oil from a mister too because sometimes vegetables have a tendency to stick even after being tossed in olive oil. Most additions can be added either before or after the vegetables are done roasting, although garlic is usually best when added before, while tapenades, basil, cilantro, parsley and marinara sauce are best added after.

Try adding: Balsamic vinegar (for sweet peppers), other roasted veggies. Roasted peppers are also great for topping burgers and sandwiches or adding to salads.
