When you first think about firing up the grill this summer, veggies might not be the first thing you think of.  Take it from us – there’s something irresistible about grilled vegetables in the summertime to make them sweet, smoky, and full of flavor. 

Whether you’re looking to level up your cookout sides or make veggies the star of the show, mastering the grill starts with a few simple techniques. We’re breaking down how to grill vegetables so you can feel confident making delicious vegetable meals and side dishes this summer.

What Vegetables Grill Well?

There’s good news about grilling your summer veggies: Most vegetables take well to grilling, you just need to prep them properly. Some of our favorites on the grill include:

• Zucchini and summer squash – Slice lengthwise for grill marks and great texture.
  
• Bell peppers – Their natural sugars caramelize beautifully over high heat.
  
• Asparagus – Thin spears grill fast and deliver bold, smoky flavor.
  
• Onions and eggplant – Hearty and durable, perfect for longer grill times.
  
• Corn on the cob – A summer classic that grills well in or out of the husk.
  
• Mushrooms – Meaty texture and great for absorbing marinades.
  

Our Pro Tip: Buy what’s in season locally. Fresher produce equals better taste, and often needs little more than olive oil, your favorite seasoning, and a quick grill to shine. 

How to Grill Vegetables for the Best Results

Grilling vegetables isn’t just about tossing them over flame. Here’s how to set yourself up for success:

1. Prep with Purpose

• Slice veggies into consistent thickness (about ½ inch is ideal) to ensure even cooking.
  
• Expose wide, flat surfaces for maximum grill contact (and those coveted char marks). For example, slice bell peppers into large, flat panels.
  

2. Use the Right Oil

• Brush veggies with a light coating of oil to prevent sticking and burning.
  
• While neutral oils like canola work, extra-virgin olive oil adds flavor depth that complements nearly every vegetable.
  

3. Consider a Grill Basket

• For small or thin-cut vegetables like cherry tomatoes or green beans, a grill basket keeps them from falling through the grates and makes turning easier.
  

4. Season & Marinate Smart

• Don’t forget seasoning! Salt and pepper go a long way, but you can add delicious blends like Weber® Red, White & BBQ All-Purpose Grilling Seasoning, Weber® Roasted Garlic & Herb Seasoning, or Weber® Buffalo Trace™ Whiskey Flavored Seasoning to elevate things even further.
  
• For extra flavor, marinate vegetables at room temperature for 20–60 minutes before grilling.

Grilling Vegetables: Final Tips

• Keep a close eye: Veggies cook fast and can go from caramelized to burnt quickly.
  
• Don’t overcrowd: Give each piece some space so they sear, not steam.
  
• Serve hot or room temp: Grilled veggies are just as delicious warm off the grill as they are tossed into a room-temperature salad.
