How to BBQ Vegetables: A Guide for Delicious Grilled Veggies


Barbecuing is a popular cooking method in the UK, especially during the warm summer months when people enjoy gathering outdoors and firing up the grill. While barbecues are often associated with meats like burgers and sausages, grilling vegetables can be just as delicious and satisfying. In this article, we will explore the art of BBQing vegetables, providing you with tips, techniques, and delicious recipes to elevate your next outdoor feast.

Why BBQ Vegetables?

Grilling vegetables not only adds a unique smoky flavor, but it also imparts a nice charred exterior while retaining their natural crunchiness. The high heat of the barbecue caramelizes the natural sugars present in vegetables, enhancing their sweetness and creating a delightful taste. Moreover, grilling vegetables is a healthy alternative to traditional meat-heavy barbecues, offering a variety of nutrients, fiber, and antioxidants vital for our well-being.

Choosing the Right Vegetables

Not all vegetables are created equal when it comes to grilling. Some vegetables are more suitable for the high heat of a barbecue, while others may require pre-cooking or different preparation methods. Here are some vegetables that work exceptionally well on the grill:

  • Sweet bell peppers
  • Zucchini
  • Eggplant
  • Asparagus
  • Corn on the cob
  • Mushrooms
  • Onions

These vegetables have a firm texture and can withstand direct heat without becoming overly soft or falling apart. You can also experiment with root vegetables like carrots or parsnips by slicing them into thicker pieces so they cook evenly.

Preparing Vegetables for the BBQ

Properly preparing vegetables before grilling is crucial to ensure even cooking and enhance their flavors. Here are some essential steps to follow:

  1. Wash the vegetables thoroughly to remove any dirt or debris.
  2. Trim the ends, remove any tough stems or leaves, and peel if necessary.
  3. Cut the vegetables into uniform sizes to ensure even cooking. For example, slice bell peppers into strips, eggplant into rounds, and zucchini into planks.
  4. Soak wooden skewers in water for at least 30 minutes before threading the vegetables. This prevents the skewers from burning during grilling.
  5. Brush the vegetables with olive oil or your preferred marinade to add flavor and prevent them from sticking to the grill. Season with salt, pepper, and any desired herbs or spices.

By taking these preparation steps, you will set yourself up for success when grilling vegetables on a barbecue.

Grilling Techniques for Vegetables

Grilling vegetables requires a slightly different approach than grilling meats. Here are a few techniques to help you achieve perfectly grilled veggies every time:

“When grilling vegetables, it is essential to control the heat and maintain a medium-high temperature. Too much heat can char the veggies quickly, while insufficient heat may cause them to become mushy.” – Chef John Smith

Indirect Heat Method:

  1. Preheat your barbecue to medium-high heat.
  2. If using charcoal, bank the coals on one side of the grill to create a hot zone and a cooler zone.
  3. If using a gas grill, turn off one set of burners to create the cooler zone.
  4. Place the vegetables directly over the hot zone to sear and develop grill marks.
  5. Once they have achieved a desirable char, move them to the cooler zone to finish cooking indirectly. This ensures even cooking and prevents burning.

Direct Heat Method:

  1. Preheat your barbecue to medium-high heat.
  2. Place the vegetables directly over the heat source.
  3. Keep a close eye on them and flip them occasionally to prevent excessive charring.

Remember, different vegetables will require different cooking times, so keep an eye on them and adjust accordingly.

Flavoring Options

While grilled vegetables are delicious on their own, you can take them to the next level by adding additional flavors. Here are a few ideas:

“Marinating vegetables before grilling not only adds flavor but also helps to keep them moist and tender.” – Chef Emily Davis

  • Marinate the vegetables in a mixture of olive oil, balsamic vinegar, garlic, and herbs for at least 30 minutes before grilling.
  • Brush the vegetables with a savory glaze during the last few minutes of grilling. Try mixing soy sauce, honey, and ginger for an Asian-inspired twist.
  • Sprinkle grated Parmesan cheese over grilled veggies just before serving for a tangy kick.

Feel free to experiment with different flavor combinations to find your favorite.
