Now that you know all about the benefits of using olive oil when grilling vegetables, let’s learn how to grill them in foil packets. Here is a simple tutorial.

🥕Pick your vegetables

Choosing vegetables is a bit tricky. The vegetables listed above may be suitable for grilling, but you may want to group them into different packets. Some vegetables are mushy, and others are crisp, so you may want to avoid joining them in one foil packet.

Crunchy veggies like beets, onions, bell peppers, and corns take longer to cook. In comparison, soft vegetables such as mushrooms and tomatoes take lesser time. So, it is better to grill them in separate foil packets.

🥕Prepare your vegetables

You may want to marinate the vegetables in olive oil and herbs and leave it in the refrigerator several hours before grilling. Slice the vegetables according to their recommended sizes. Then, slice the onion into thick slices and the zucchini, eggplant, and carrots into thick slices or spears. Leave corn on the cob as is.

Take them out of the refrigerator 30 minutes before grilling them.

🥕Add seasonings

If you would like to add some seasonings, do so now. You can add salt, freshly ground pepper, garlic powder, or other desired herbs like basil, rosemary, and thyme. Enhance the flavor by adding olive oil and salt.

🥕Prepare the foil packets

Take a large sheet of aluminum foil and place it in front of you so that the long side is facing you. Fold the bottom of the foil up about 2-3 inches so that it creates a sturdy base to place the food on.

Using a pastry brush, you can paint the foil with olive oil to prevent the veggies from sticking to the foil. Place the vegetables in the center of the foil, and drizzle with olive oil. If desired, add any seasonings at this time.

Bring the two long sides of the foil up together and fold them over several times until they are securely closed. Make sure there are no openings for the food to escape.

🥕Preheat grill

Preheat grill over low or indirect heat.

🥕Grill the vegetables

Place the foil packets on the grill. Cook for about 10 minutes or until the vegetables are cooked to your preference. Use tongs to flip the packet, and leave it for another eight to ten minutes.

The grilling time usually depends on the heat of the grill and the variety of vegetables you’re cooking. Check for doneness and remove from heat when finished.

🥕Serve grilled vegetables

When you’re done, remove the vegetables from the packets and enjoy! You can serve them as they are or over a bed of rice or salad. Experiment with different marinades and flavors to find what you like best. With these simple steps, you can grill delicious and healthy vegetables in no time!

More Grilling Tips

Grilled Food, From The Tablegrill, Grilled Meats

Grilling is one of the healthiest and easiest food preparations. Not only does it give your food a smoky and savory flavor, but it also seals in the juices, making the food more tender and moist. Here are some tips to get better results with your grilled food.

✔Lightly oil the vegetables

One mistake people often make when grilling vegetables is oiling them too much. Brush them with a light coating of oil to prevent them from sticking to the foil, and that’s it. Over-oiling will make your veggies greasy and may cause them to flare up on the grill.

✔Don’t overcrowd the grill

If you’re cooking a lot of food at once, don’t try to cram everything on the grill at once. It will decrease the grill temperature, leading to uneven cooking and poor results. Grill food in batches instead, so everything is cooked evenly.

✔Create a marinade

If you want your vegetables to be extra flavorful, consider creating a marinade. You can use olive oil, balsamic vinegar, soy sauce, or any other desired seasonings. Marinades add flavor and moisture to the food, and they also help keep it from sticking to the grill.

✔Know proper grilling time

Not all vegetables are created equal. Some cook faster than others, so it’s essential to know how long to grill them for the best results. It would be best to grill zucchini and eggplant for eight to ten minutes and thicker vegetables like carrots for fifteen minutes.

✔Use a thermometer

One of the essential things for successful grilling is knowing when your food is done. To make sure your meat or vegetable is cooked perfectly, use a thermometer. You want them to be cooked through but not overcooked to the point of being mushy.

✔Use a grill pan

If you don’t have a grill, or if the weather isn’t cooperating, don’t worry! You can still enjoy grilled vegetables by using a grill pan. It is an excellent option for smaller kitchens or limited space. Heat the pan over medium-high heat and cook the veggies like you would on the grill.
