BBQ Grilled Vegetables: Your Next Favorite Meal

Grilled vegetables are a secret weapon for any self-respecting Argentine Asador— the unsung heroes of any BBQ. With instinct and precision, an Asador uses fire and seasoning to release and elevate the natural flavors of the vegetables, making them the perfect complement to an Argentine-style asado or a healthy, delicious addition to any BBQ. Sweet, tangy, and fresh flavors, combined with creamy yet crisp textures, and a hint of smoke… perfectly charred vegetables deliver all of this and more. 

At Gaucho Life, we believe in grilling with care and craftsmanship. Whether you’re using a traditional parrilla or one of our Argentinian Grills, mastering fire and seasoning transforms simple vegetables into an unforgettable meal.

Best Vegetables for BBQ Grilling

Bad news first: Not every vegetable is equally suited to grilling. While some vegetables don't hold up well to high heat, others stand out for their ability to maintain their shape, resist burning, and, of course, for how grilling enhances their flavor and texture. Popular grilled vegetables include:

• Zucchini and corn. Zucchini is perfect for grilling, thanks to its firm yet tender texture and high water content, which ensures it stays juicy and absorbs flavors well. Corn intensifies its sweetness when grilled, developing a slightly crunchy texture that delights the palate.

• Bell peppers and onions. These vegetables become sweeter as they caramelize over the heat, acquiring a delicious smoky flavor. When stuffed with melting cheese and raw eggs, which cook inside half of the vegetable, they transform into a true delicacy.

• Mushrooms, asparagus, and eggplant. Larger mushrooms, like portobellos, hold up well on the grill because of their meaty texture. They develop a deep, earthy flavor that pairs beautifully with marinades. Eggplant softens and gains a rich, smoky flavor. Asparagus cooks quickly on the grill and develops a rich, nutty taste.

• Carrots and sweet potatoes. These hearty vegetables add variety and substance to your meals. Their outsides crisp up while their insides soften, and the heat brings out their natural sweetness. A slight smoky zing enhances their flavor, making them the perfect garnish or main dish for grilled meals.

Pro Tip: Opt for seasonal vegetables for peak freshness and flavor. Argentine classics like provoleta (grilled cheese) can also pair beautifully with your grilled veggies.

Preparing Vegetables for the Grill

For outstanding results, BBQ grilled vegetables should be properly prepared—sliced and seasoned— before hitting the grill. 

Uniform slicing, for instance, ensures that the veggies cook evenly and keep and maintain their texture, while marinades and seasoning elevate their flavor. Here's a breakdown:

• Zucchini. Slice lengthwise into ½-inch pieces. Thicker slices hold up better on the grill without becoming mushy. Chimichurri, lemon juice, and olive oil brighten the zucchini’s flavor and add a fresh twist.

• Bell peppers. Cut into quarters or large strips to prevent them from falling through the grill grates. Be sure to remove the seeds and ribs to avoid an unpleasant, sour aftertaste.

• Mushrooms. You can grill mushrooms whole, halved, or without the stems. Smaller mushrooms may need grill baskets, cast iron pans, or griddles to avoid losing them through the grates. 

• Onions. Cut into thick rounds or wedges to keep them intact on the grill. Marinating them with garlic, olive oil, lemon juice, and chimichurri takes their flavor to the next level.

• Eggplant. Slice into ½-inch thick rounds or long slices since thin slices tend to become mushy. Season with olive oil and chimichurri for a rich, deep flavor.

• Corn. You can grill it without the husk, though leaving part of it intact helps protect the kernels. Soaking the corn in water for 15 minutes beforehand prevents it from drying out.

• Asparagus. The natural nuttiness of asparagus pairs perfectly with chimichurri and minced garlic. Trim the woody ends and leave the spears whole before grilling.

• Sweet potatoes. Cut into wedges about ¼ to ½ inch thick, for preventing burning. Coat generously with olive oil to promote caramelization, and complement with chimichurri to balance the sweetness with acidity and a herbal kick

• Carrots. Use cast iron pans for slices to prevent them from falling through the grates, or leave smaller carrots whole. A drizzle of olive oil and garlic enhances their natural sweetness, while chimichurri and lemon juice add a delightful contrast.

How to Grill Vegetables to Perfection

Now that we’ve warmed up on the topic of BBQ grilled vegetables, it’s time to dive into the steps for grilling them perfectly—Argentine style.

• Preheat the grill. Once your vegetables are properly sliced and marinated, turn on the grill and set it to medium-high heat (around 400°F). For wood-fired grills, the ideal temperature is reached when you can hold your hand near the fire for no more than 4-5 seconds. 

• Define heat zones. Create two heat zones: one directly over the coals and one away from them. This allows you to rotate between direct heat for quick cooking and char marks and indirect heat for slower cooking of denser vegetables.

• Oil the grates. Brush the grill with high-temperature cooking oil, and coat the sliced vegetables with oil to prevent sticking. Use a wood scraper or a paper towel soaked in oil, holding it with tongs to avoid burns.

• Grilling time + flip and rotate. Place the vegetables on the grill over direct heat. Avoid flipping too early to prevent tearing and ensure perfect char marks. Char marks naturally release the vegetables from the grill, so if they stick, wait a little longer before flipping. Grilling times vary depending on the vegetable and how it’s sliced. For example:

Vegetable	Grill Time per Side	Total Grill Time	Pro Tips
Zucchini & Eggplant	10 minutes	20 minutes	Brush lightly with olive oil to prevent sticking
Mushrooms	—	6-10 minutes depending on size	Use griddles or grill baskets. Flip when brown.
Corn	Rotate every 3-4 minutes	30-35 minutes	Leave the husk on to protect the kernels
Bell Peppers	15-20 minutes	30-40 minutes	Grill skin-side down until it blisters and chars
Onions	6 minutes for thick slices	40 minutes for a whole onion	Marinate to enhance flavor
Asparagus	Turn every 3-5 minutes	6-10 minutes	Trim the woody ends, leaving the spears whole
Dense Vegetables	4-5 minutes (direct heat)	10-12 minutes (indirect heat)	Use a grill lid to create an oven-like environment

 

• Use indirect heat.  For dense vegetables like carrots and sweet potatoes, indirect heat ensures even cooking without burning. Start by placing them over direct heat for 4-5 minutes to develop char marks. Then move them to indirect heat for another 10-12 minutes. Using a grill lid helps create an oven-like environment, speeding up cooking and ensuring even results.

Gaucho Life Tip: For an optimal grilling experience, it’s essential to control heat zones. Santa Maria Grills are ideal for this, allowing you to balance direct and indirect heat for perfectly charred yet tender vegetables.

Serving Ideas for BBQ Grilled Vegetables

BBQ grilled vegetables are an incredibly versatile dish that can serve as a hearty side, a light main course, or a delicious addition to other meals. Burgers topped with grilled bell peppers and onions, for instance, are simply delicious. Grilled mushrooms, on the other hand, pair perfectly with a rocket, avocado, and parmesan salad, adding a sizzling layer of earthy flavor.

Light, fresh vegetables like zucchini and asparagus make ideal complements for grilled chicken, offering a flavorful, light meal. A drizzle of lemon-garlic dressing can brighten the dish even further. However, on colder days when you need something more filling, hearty grilled vegetables such as sweet potatoes and carrots pair seamlessly with heavier cuts like grilled steak or ribs.

Alternatively, you can serve BBQ veggies as the main dish by creating a vegetarian asado platter. Be sure to include all the must-haves of an Argentine asado (excluding meat, of course), such as grilled cheese (provoleta), charred bread, and bold dressings like aioli and chimichurri. To make it even heartier, include grains like quinoa, couscous, or farro for a satisfying vegetarian meal.

Additionally, enhance the richness, texture, and contrast of your grilled vegetables by adding flavorful toppings such as crumbled feta or goat cheese, fresh herbs, toasted nuts, or a drizzle of balsamic glaze or reduction. This will elevate them into a top-quality dish, perfect for an assorted Picada (a typical Argentine appetizer) or as a first-class side dish.

Health Benefits of Grilled Vegetables

Grilled vegetables are not only perfect for those seeking new flavors and textures, but also for anyone in search of healthy meals with high nutritional value. Unlike other cooking methods, such as boiling or frying, grilling ensures that vegetables retain most of their nutrients during the cooking process, making them an excellent source of vitamins, fiber, and minerals.

Additionally, grilling enhances the natural sugars in vegetables, giving them a caramelized, smoky flavor without the extra calories associated with excessive oil or heavy dressings. This makes grilled vegetables an ideal choice for low-carb, vegetarian, and keto diets. However, it's important to select vegetables that are naturally low in carbohydrates—such as zucchini, mushrooms, bell peppers, and asparagus—and to lightly coat them with healthy fats like olive oil. Fresh dressings and simple seasonings, such as herbs, garlic, and lemon juice, will add even more flavor without introducing unhealthy fats or excess sodium.

Common Mistakes to Avoid When Grilling Vegetables

Although grilling vegetables is relatively straightforward, even the most experienced grillers can occasionally fall into a pitfall if proper care isn’t taken. Some common mistakes when grilling vegetables include:

• Overcrowding the grill. This limits airflow, causing the vegetables to steam instead of char and preventing caramelization. Leaving space between vegetables or grilling in batches can help avoid this issue.

• Not preheating the grill.  Skipping this step can result in uneven cooking or vegetable tearing, as the absence of quick searing leads to inconsistent texture. Checking the temperature and defining grill zones are additional important steps to consider.

• Skipping or overapplying oil. Brush the grill with oil before placing the vegetables to create a non-stick surface. However, avoid excessive oiling, as too much oil can lead to flare-ups.

• Unevenly cutting. When vegetables are cut unevenly, doneness tends to be inconsistent. Ideally, match size with cooking time: cut lighter vegetables into larger pieces to prevent overcooking, and denser ones into thinner pieces to ensure they cook through without burning on the outside.

Do I need to marinate vegetables before grilling?

Although marinating vegetables before grilling isn’t necessary, it is recommended because it enhances flavor and helps them stay moist on the grill. In most cases, a simple oil and spice rub right before grilling is enough to elevate the meal.

What vegetables should I avoid grilling?

Avoid grilling water-dense vegetables, such as cucumbers, and leafy greens like lettuce and spinach. These vegetables do not hold up well to grilling and may wilt or become mushy. A cast-iron pan is a suitable alternative for cooking them.

What’s the best grill for vegetables?

Grills with temperature control and a cast-iron grate (like those in Gaucho Life’s collection) are ideal for cooking vegetables, as they ensure even heat distribution and offer advanced features to manage heat zones effectively.

Can I grill frozen vegetables?

Yes, you can grill frozen vegetables. However, make sure to thaw them first to avoid excess moisture. This will ensure proper charring and prevent steaming.
