The Best Vegetables to Grill & How to Do It Right

Colorful grilled vegetables including zucchini, bell peppers, asparagus, corn and mushrooms with char marks

Grilled vegetables are one of the most underrated things you can cook on a BBQ. The high heat caramelizes their natural sugars, the smoke adds incredible depth, and those beautiful char marks make everything look and taste like it came from a restaurant kitchen. At Smokey's BBQ, we believe vegetables deserve a prime spot on the grill. Here's your complete guide.

🔥 The Golden Rules of Grilling Vegetables

  • Cut uniformly — Even thickness means even cooking. Aim for ½ inch slices for most vegetables.
  • Oil generously — Coat all sides with olive oil to prevent sticking and promote caramelization.
  • Season well — Salt, pepper, and garlic powder at minimum. Don't be shy.
  • Use high heat — You want char marks and caramelization, not steaming. Keep the grill hot.
  • Don't overcrowd — Give vegetables space so they sear rather than steam.
  • Watch carefully — Vegetables cook fast. Stay at the grill and flip when you see good color.

🥦 The Best Vegetables for the Grill

1. Corn on the Cob

Prep: Grill in the husk for 15 minutes (turning occasionally), then peel and char directly over flame for 2–3 minutes.
Or: Shuck, brush with butter, and grill directly for 10–12 minutes, turning every 2–3 minutes.
Serve with: Herb butter, cotija cheese, chili powder, and lime (elote style) or simply with salted butter.

2. Bell Peppers

Prep: Cut into quarters or thick strips, remove seeds, brush with olive oil.
Grill: 4–5 minutes per side over medium-high heat until charred and tender.
Pro tip: Place charred peppers in a sealed bag for 10 minutes — the steam loosens the skin for easy peeling. Incredible in sandwiches, salads, and pasta.

3. Zucchini & Summer Squash

Prep: Slice lengthwise into ½ inch planks or cut into rounds. Brush with olive oil, season with salt, pepper, and Italian herbs.
Grill: 3–4 minutes per side over medium-high heat.
Serve with: A drizzle of balsamic glaze and fresh basil, or crumbled feta cheese.

4. Asparagus

Prep: Snap off woody ends, toss with olive oil, salt, and pepper. Grill perpendicular to grates so they don't fall through.
Grill: 3–4 minutes total, rolling occasionally, until tender with light char.
Serve with: Lemon zest, shaved parmesan, and a drizzle of olive oil. Elegant and delicious.

5. Portobello Mushrooms

Prep: Remove stems, brush caps with olive oil and balsamic vinegar, season with garlic powder, salt, and pepper.
Grill: 4–5 minutes per side over medium heat, gill-side up first.
Pro tip: Portobello caps make an incredible meat-free burger alternative. Top with melted cheese, roasted peppers, and aioli on a toasted bun.

6. Eggplant

Prep: Slice into ½ inch rounds, salt and let sit 15 minutes to draw out moisture, pat dry, brush with olive oil.
Grill: 4–5 minutes per side over medium-high heat until tender and nicely charred.
Serve with: Tahini sauce, fresh mint, and pomegranate seeds for a Middle Eastern-inspired dish.

7. Red Onions

Prep: Slice into ½ inch rounds (keep rings intact), brush with olive oil and season.
Grill: 4–5 minutes per side over medium heat until caramelized and tender.
Pro tip: Use a toothpick or skewer through the rings to keep them together while grilling.

8. Romaine Lettuce

Prep: Cut heads in half lengthwise, brush cut side with olive oil.
Grill: 2–3 minutes cut-side down over high heat until charred.
Serve with: Caesar dressing, shaved parmesan, and croutons for a stunning grilled Caesar salad. A guaranteed crowd-pleaser.

🌿 The Ultimate Grilled Veggie Marinade

This simple marinade works beautifully on almost any vegetable:

  • ¼ cup olive oil
  • 2 tbsp balsamic vinegar
  • 2 cloves garlic (minced)
  • 1 tsp dried Italian herbs
  • Salt & pepper to taste

Toss vegetables in marinade and let sit for 30 minutes before grilling. The balsamic adds beautiful caramelization and a slightly sweet, tangy flavor.
