Barbecuing isn’t just for burgers and steaks anymore. The world of grilled vegetables is bursting with flavor, offering a healthy and delicious alternative or complement to traditional BBQ fare. But which vegetables truly shine over the open flame? This guide explores the best vegetables to grill, offering tips, tricks, and ideas to elevate your BBQ game.
Unlocking the Flavor Potential of Grilled Vegetables
Many people might initially think that only a few vegetables are suitable for grilling. However, with the right preparation and techniques, almost any vegetable can be transformed into a smoky, caramelized masterpiece. The key lies in understanding the vegetable’s texture, moisture content, and optimal cooking time. Properly grilled vegetables should be tender-crisp, slightly charred, and infused with smoky flavor.
Prepping Your Veggies for BBQ Success
Preparation is paramount. Start by selecting fresh, high-quality vegetables. Wash and dry them thoroughly. Then, consider how you’ll be grilling them – whole, sliced, or skewered.
Cutting vegetables into uniform sizes ensures even cooking. Larger, denser vegetables like potatoes and squash may require pre-cooking to ensure they’re fully cooked before they char on the outside. Marinating vegetables adds flavor and helps prevent them from drying out on the grill. A simple marinade of olive oil, herbs, garlic, and lemon juice can work wonders.
Top Vegetables for the BBQ: A Deep Dive
Let’s explore some of the most popular and rewarding vegetables to grill. We’ll cover preparation tips, grilling techniques, and flavor pairings for each.
Bell Peppers: Sweet and Smoky Perfection
Bell peppers are a BBQ staple for a reason. Their natural sweetness intensifies when grilled, and their sturdy structure holds up well to the heat.
Preparation: Halve or quarter bell peppers, removing the seeds and membranes. Consider grilling them whole until the skin is blackened, then transferring them to a bowl covered with plastic wrap to steam. Once cooled, the skins will easily peel off, leaving you with tender, smoky peppers.
Grilling: Grill over medium heat, turning occasionally, until tender and slightly charred.
Flavor Pairings: Bell peppers pair well with onions, zucchini, eggplant, and herbs like oregano and thyme. They’re also fantastic in fajitas, salads, and as a topping for burgers and sandwiches. A drizzle of balsamic glaze or a sprinkle of feta cheese adds a burst of flavor.
Corn on the Cob: A Summer Classic
Grilled corn on the cob is a quintessential summer treat. The smoky char complements the corn’s natural sweetness, creating a truly irresistible flavor.
Preparation: You can grill corn in its husk or shuck it completely. Soaking corn in its husk in water for at least 30 minutes before grilling prevents it from burning. If grilling shucked corn, brush it with melted butter or oil.
Grilling: Grill in the husk over medium heat for 15-20 minutes, turning occasionally. For shucked corn, grill over medium heat for 8-10 minutes, turning frequently, until kernels are tender and slightly charred.
Flavor Pairings: Butter, salt, and pepper are classic toppings for grilled corn. Experiment with chili powder, lime juice, cotija cheese, or a compound butter flavored with herbs and garlic. Grilled corn kernels can also be cut off the cob and used in salads, salsas, and side dishes.
Eggplant: Rich and Meaty Flavor
Eggplant’s meaty texture and ability to absorb flavors make it an excellent grilling candidate.
Preparation: Slice eggplant into 1/2-inch thick rounds or planks. Salting the eggplant for 30 minutes before grilling helps draw out excess moisture and reduces bitterness. Pat dry before grilling.
Grilling: Grill over medium heat, turning occasionally, until tender and slightly charred.
Flavor Pairings: Eggplant pairs well with garlic, tomatoes, basil, oregano, and olive oil. It’s a key ingredient in dishes like baba ghanoush and ratatouille. Grilled eggplant can also be used in vegetarian sandwiches or as a topping for pizza. A sprinkle of Parmesan cheese or a drizzle of balsamic glaze adds a delicious finishing touch.
Asparagus: A Delicate Delight
Asparagus spears grill quickly and develop a wonderful smoky flavor. Their slender shape makes them perfect for grilling in bundles or on a grill basket.
Preparation: Snap off the tough ends of the asparagus spears. Toss with olive oil, salt, and pepper.
Grilling: Grill over medium heat for 5-7 minutes, turning occasionally, until tender-crisp.
Flavor Pairings: Asparagus pairs well with lemon, garlic, Parmesan cheese, and balsamic vinegar. It’s a great side dish for grilled chicken, fish, or steak. Grilled asparagus can also be added to salads or used as a topping for bruschetta.
Zucchini and Summer Squash: Quick and Easy
Zucchini and summer squash are quick-cooking vegetables that grill beautifully. Their mild flavor makes them versatile and receptive to different seasonings.
Preparation: Slice zucchini and summer squash into 1/4-inch thick rounds or planks. Toss with olive oil, salt, and pepper.
Grilling: Grill over medium heat for 3-5 minutes per side, until tender and slightly charred.
Flavor Pairings: Zucchini and summer squash pair well with herbs like basil, oregano, and thyme. They’re also delicious with garlic, lemon, and Parmesan cheese. Grilled zucchini and summer squash can be used in salads, pasta dishes, or as a side dish.
Onions: Sweet and Smoky
Grilling onions brings out their natural sweetness and adds a smoky char.
Preparation: Slice onions into 1/2-inch thick rounds or wedges. Toss with olive oil, salt, and pepper.
Grilling: Grill over medium heat, turning occasionally, until tender and slightly charred.
Flavor Pairings: Onions pair well with bell peppers, zucchini, eggplant, and herbs like thyme and rosemary. They’re a classic addition to burgers, sandwiches, and kebabs. Grilled onions can also be caramelized and used as a topping for pizza or steak.
Potatoes: Hearty and Satisfying
Grilled potatoes offer a hearty and satisfying alternative to baked or fried potatoes.
Preparation: Smaller potatoes like fingerling or new potatoes can be grilled whole. Larger potatoes should be cut into wedges or slices. Pre-cooking potatoes in boiling water for 5-10 minutes before grilling helps ensure they’re fully cooked. Toss with olive oil, salt, pepper, and your favorite herbs.
Grilling: Grill over medium heat, turning occasionally, until tender and slightly charred.
Flavor Pairings: Potatoes pair well with rosemary, thyme, garlic, and Parmesan cheese. They’re a great side dish for grilled meats and vegetables. Grilled potatoes can also be used in salads or as a base for loaded fries.
Mushrooms: Earthy and Umami-Rich
Mushrooms absorb smoky flavors beautifully, becoming tender and umami-rich on the grill.
Preparation: Larger mushrooms like portobellos can be grilled whole. Smaller mushrooms like cremini or button mushrooms can be skewered or grilled in a grill basket. Brush with olive oil, salt, pepper, and your favorite herbs.
Grilling: Grill over medium heat, turning occasionally, until tender and slightly charred.
Flavor Pairings: Mushrooms pair well with garlic, thyme, rosemary, and balsamic vinegar. They’re a great addition to burgers, sandwiches, and kebabs. Grilled mushrooms can also be used in pasta dishes or as a side dish.
Grilling Techniques: Mastering the Flame
Different vegetables require different grilling techniques to achieve optimal results. Here are some tips for mastering the flame:
- Direct Heat: Grilling directly over the heat source is ideal for vegetables that cook quickly, such as asparagus, zucchini, and bell peppers.
- Indirect Heat: Grilling indirectly, away from the direct heat, is best for vegetables that require longer cooking times, such as potatoes, corn on the cob, and whole eggplants.
- Grill Baskets: Grill baskets are essential for grilling small or delicate vegetables that might fall through the grates.
- Skewers: Skewering vegetables is a great way to create colorful and flavorful kebabs. Be sure to soak wooden skewers in water for at least 30 minutes before grilling to prevent them from burning.
Marinating for Maximum Flavor
Marinating vegetables before grilling is a simple way to add flavor and keep them moist. A basic marinade consists of olive oil, an acid (such as lemon juice or vinegar), herbs, and seasonings. Experiment with different flavor combinations to find your favorites. Marinating for at least 30 minutes allows the flavors to penetrate the vegetables.
Safety First: Grilling Precautions
Grilling can be a fun and rewarding experience, but it’s important to take safety precautions to prevent accidents.
- Never leave a grill unattended.
- Keep children and pets away from the grill.
- Use long-handled grilling tools to avoid burns.
- Ensure the grill is placed on a stable surface.
- Have a fire extinguisher or water nearby in case of emergencies.

What makes a vegetable good for grilling?
Several factors contribute to a vegetable’s grillability. A firm texture is key; vegetables like bell peppers, zucchini, and eggplant hold their shape well and don’t fall through the grates. Natural sugars also enhance grilling as they caramelize under the heat, creating a delicious smoky sweetness. Consider moisture content too; excessively watery vegetables can steam rather than grill, while those with higher fat content, like avocados, become wonderfully creamy.
Besides the vegetable itself, consider its preparation. Cutting vegetables into larger pieces prevents them from slipping through the grill. Marinating adds flavor and moisture, helping vegetables to cook evenly and preventing them from drying out. Thinking about the specific flavors you want to achieve, and then choosing vegetables that lend themselves to those flavors, will significantly impact the final deliciousness.
How do I prevent vegetables from falling through the grill grates?
The most straightforward solution is to cut your vegetables into larger, thicker pieces. This ensures they have enough surface area to sit securely on the grates. Skewering smaller vegetables like cherry tomatoes, mushrooms, or onions is another effective method. Metal skewers can be reused, while wooden skewers should be soaked in water for at least 30 minutes beforehand to prevent them from burning.
Another option is to use a grill basket or a sheet of aluminum foil. Grill baskets allow smoke to circulate while keeping smaller items contained. If using foil, poke holes in it to allow some of the smoke to reach the vegetables; otherwise, they’ll steam rather than grill. Remember to lightly oil the grill grates or basket to prevent sticking, regardless of the method you choose.
What’s the best way to marinate vegetables for grilling?
The best marinades for grilling vegetables typically include an oil (like olive or avocado oil) for moisture and to help prevent sticking, an acid (such as lemon juice, vinegar, or balsamic glaze) to tenderize and brighten the flavors, and seasonings (herbs, spices, garlic, etc.) to enhance the taste. Experiment with different flavor combinations to find what you enjoy most. A simple marinade of olive oil, lemon juice, garlic, and herbs is a great starting point.
Allow vegetables to marinate for at least 30 minutes, or up to several hours in the refrigerator. Avoid marinating for too long, as the acid can break down the vegetables’ texture, making them mushy. Before grilling, remove the vegetables from the marinade and pat them dry to ensure they brown properly on the grill and don’t steam in the marinade.
How do I know when grilled vegetables are done?
The doneness of grilled vegetables depends on the type of vegetable and your personal preference. Generally, vegetables are done when they are tender-crisp and slightly charred. Use a fork or skewer to test for tenderness; it should pierce the vegetable easily but still offer some resistance. Look for grill marks and slight softening of the vegetable’s flesh.
Keep in mind that different vegetables will cook at different rates. Heartier vegetables like potatoes and carrots will take longer than softer vegetables like zucchini and bell peppers. Group vegetables with similar cooking times together on the grill. Remove vegetables from the grill as they are done to prevent overcooking. Overcooked vegetables will become mushy and lose their flavor.
Can you grill leafy greens like lettuce or spinach?
While not typically the first choice for grilling, some leafy greens can be grilled briefly to add a smoky flavor. Romaine lettuce, for example, can be cut in half lengthwise and grilled cut-side down for just a minute or two until slightly wilted and charred. This adds a unique smoky flavor and slightly softens the lettuce, making it a great addition to salads.
Delicate greens like spinach and arugula are generally not suitable for direct grilling as they will wilt and burn very quickly. However, they can be used in grilled wraps or quesadillas or placed in a grill basket for a very brief cooking period. The key is to use high heat and grill for a very short time to avoid complete disintegration. Consider the smoke flavor as the primary goal rather than thorough cooking.
What are some unique or unexpected vegetables to try grilling?
Beyond the usual suspects, there are many unique vegetables that are fantastic when grilled. Radicchio, with its slightly bitter flavor, mellows out and sweetens beautifully on the grill. Endive also benefits from grilling, becoming less bitter and more caramelized. Try grilling halved heads of cabbage for a smoky, slightly sweet side dish.
Avocados are another unexpected grilling superstar. Cut them in half, remove the pit, and grill cut-side down until they develop grill marks and become slightly softened. The heat enhances their creamy texture. Also, consider grilling sweet potatoes whole or in large wedges for a smoky sweetness that complements their natural flavor. The possibilities are endless – don’t be afraid to experiment!
What are some tips for keeping grilled vegetables from drying out?
One of the most important tips for preventing dry grilled vegetables is to ensure they are properly oiled or marinated before grilling. The oil helps to create a barrier that prevents moisture from escaping during the cooking process. Marinating not only adds flavor but also infuses the vegetables with moisture from the marinade itself.
Avoid overcooking the vegetables, as this is the primary cause of dryness. Grill them until they are tender-crisp, but not mushy. Consider using indirect heat or a lower grilling temperature for longer-cooking vegetables like potatoes and carrots. If you find that your vegetables are drying out during grilling, you can lightly brush them with oil or marinade to help retain moisture. Also, closing the grill lid can help trap moisture and cook the vegetables more evenly.
