Roasting Summer Vegetables

Summer produce like zucchini, peppers, and cherry tomatoes holds a high water content. If you crowd the pan, you boil them in their own juices; give them space, and they turn deeply caramelized and concentrated.

Before you start

Size matters more than the specific vegetable.

Consistent cutting is the difference between burnt edges and raw centers. Keep your pieces around one inch.

  • Large rimmed baking sheet
  • Chef's knife
  • Large mixing bowl
Ingredients

What goes in.

  • 2medium zucchini, cut into 1-inch chunks
  • 2bell peppers, seeded and cut into 1-inch squares

  • 3 tbspolive oil
  • 1 tspkosher salt
  • 1/2 tspblack pepper
The key technique

The Sizzle Start

Place your empty baking sheet in the oven while it preheats to 425°F. When the cold vegetables hit the hot metal, the searing begins instantly.

Step by step

The method.

  1. Heat the oven

    Set your oven to 425°F and slide the empty baking sheet onto the middle rack while it heats.

  2. Prep the vegetables

    Cut the zucchini, peppers, and onions into uniform pieces. Leave the cherry tomatoes whole so they burst during cooking.

  3. Season

    In a large bowl, toss the vegetables with olive oil, salt, and pepper. Ensure every surface has a light, oily sheen.

  4. Roast

    Carefully pull the hot sheet from the oven. Dump the vegetables onto the pan and spread them into a single layer with a spatula. Return to the oven.

  5. Finish

    Roast for 20 minutes, then shake the pan to flip the vegetables. Continue for another 5–10 minutes until the edges of the onions are darkened and the zucchini is tender.

Variations

Other turns to take.

Herbed Finish

Toss the vegetables with torn fresh basil or mint immediately after removing them from the oven.

Spiced Roast

Add a teaspoon of smoked paprika or dried oregano to the oil mixture before tossing.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Avoid using parchment paper if you want a true sear; the contact with the hot metal is essential.

Tip

If you have a lot of vegetables, use two pans rather than crowding one.

Tip

Place the vegetables with their cut sides down on the sheet for the best color.

Questions

The ones that keep coming up.

Why are my vegetables mushy?

Usually because of overcrowding or a too-low oven temperature. Use a larger pan and keep the heat at 425°F or higher.

Can I roast these ahead of time?

They are best eaten immediately. If you must, roast them for 5 minutes less and reheat in a hot oven.
