How to Roast Summer Vegetables


There are several options for roasting summer vegetables, but a few popular choices include:

  • Oven. Roasting vegetables in an oven is common, as it allows for even heat distribution and a crispy texture. To roast vegetables in an oven, preheat the oven to 425°F, toss the vegetables with oil and seasonings, and spread them out on a baking sheet. Roast for 15-20 minutes or until the vegetables are tender and lightly browned.
  • Skewers. This method is great for vegetables that are sturdy enough to be skewered, such as bell peppers, onions, mushrooms, and cherry tomatoes. Toss the vegetables with a small amount of oil and seasonings, then thread them onto skewers.

  • Griddle. This is a great method for vegetables that are sturdy enough to be grilled, such as bell peppers, eggplant and zucchini. Cut the vegetables into slices or chunks, toss with a small amount of oil and seasonings, then grill on a preheated griddle.
  • Cast iron skillet. A cast iron skillet gives vegetables a nice sear for a crusty finish. This method is good for vegetables with high-water content, such as zucchini or eggplant. Cut the vegetables into slices or chunks and roast in a preheated skillet with a small amount of oil over medium-high heat.

Steps for Roasting Summer Vegetables

  1. Cut the vegetables into evenly sized pieces. Like this, they will cook at the same rate. It prevents some pieces from being burnt or overcooked while others are still raw.
  2. Toss the vegetables with oil. Oil prevents the vegetables from sticking on the baking sheet and adds flavor. You can use olive oil or any other oil of your choice. Toss to ensure that the vegetables are evenly coated.
  3. Add seasonings. Seasonings add flavor to the vegetables. There is a wide range of seasonings to choose from, including herbs, garlic, lemon juice, and spices such as paprika, cumin, or cayenne pepper. Experiment with different seasonings to find the combination that you like the most.
  4. Spread the vegetables out on a baking sheet. This will ensure that the vegetables roast evenly rather than steaming. Make sure to use a baking sheet with a rim to prevent juices from spilling over.
  5. Roast at a medium to high temperature. Roasting at a high temperature, typically between 400° and 450°F (200° and 230°C), will help to caramelize the vegetables and bring out their natural sweetness. However, you need to stir or flip the vegetables occasionally to ensure they cook evenly.
  6. Check for doneness after every 5-10 minutes. Different vegetables have different roasting times. Keep a close eye on the vegetables and remove them from the oven when they are tender and slightly caramelized.
  7. Serve immediately. Roasted vegetables are best served hot when their texture and flavor are still potent.

  • Oregano – adds a strong, herby flavor that works well with vegetables like zucchini and eggplant

Don’ts of Roasting Summer Vegetables

Here are some don’ts to keep in mind when roasting summer vegetables:

  • Don’t overcrowd the baking sheet. If the vegetables are too close together, they will steam instead of roasting. Make sure to spread them out in a single layer for even cooking.
  • Don’t skimp on the oil. Vegetables need a little bit of oil to roast properly. Without enough oil, they will dry out and burn.
  • Don’t add acidic ingredients too early. Tomatoes, lemon juice, and vinegar can break down the vegetables and cause them to become mushy. Adding these ingredients at the end of the cooking time or as a finishing touch is best.
  • Don’t overcook. Vegetables can become mushy and lose their flavor if they are overcooked. Keep an eye on them and remove them from the oven when they are tender and slightly caramelized.
  • Don’t use too much seasoning. A little bit goes a long way. Be careful not to over-season the vegetables, as this can overpower the natural flavors.
  • Don’t roast all vegetables together. Some vegetables cook faster than others. It’s best to roast them separately to avoid overcooking.
  • Don’t forget to preheat the oven. Preheating the oven will ensure that the vegetables start cooking immediately and ensure even cooking.
