Grilling vegetables couldn’t be easier. There’s hardly anything to it but I recommend upgrading them with seasonings, fats or herbs like we’ve done here.

The main idea is just knowing which vegetables work well for grilling, following the simple straightforward prep method, cooking the vegetables on a preheated grill, and following the cook times directed.

Crisper vegetables will take longer to grill to a tender texture, while softer vegetables will obviously cook faster.

I also like to get a decent char on certain vegetables like the corn and peppers so put these vegetables in the areas of the grill that have hot spots (usually towards the back of the grill, or some grills like the Weber Genisis I have include a sear zone burner).

Then only put many vegetables on your grill that you can fit in a single layer. If you need to work in batches that’s just fine. You can keep them warm on a baking sheet in a 200 degree oven if needed.

This is a great option for a side to pair with pulled chicken sandwiches, turkey burgers, pan seared steak, baked chicken thighs and so much more! Or keep it vegetarian and serve the veggies over a grain boil with a dressing of your choice.

Either way you can’t go wrong here! So much fresh goodness in every bite.

What Vegetables Work Best for Grilling?

  • Fruits: Certain foods of this group that we confuse as vegetables grill up well. This includes things like peppers, tomatoes, zucchini, squash, okra, avocado, and eggplant.
  • Legumes: Pea pods and beans will grill up just fine but it’s the size that makes them awkward on the grill. If you have a grilling basket or grid this is recommend for these vegetables.
  • Cruciferous vegetables: Including broccoli, cauliflower, cabbage, kale and Brussels sprouts will all grill rather well. Depending on the size you may opt to grill on a grill sheet set over the grill grates or a sheet of foil so it’s easier to work with smaller pieces and so they don’t fall through grill grates.
  • Allium vegetables: Bulb onions, green onions, leeks, shallot and garlic all grill up well. With garlic you’ll want keep as a whole bulb (only slicing the top end of to expose cloves), coat with oil and wrap with foil to grill.
  • Other vegetables: Corn, mushrooms and asparagus are other excellent options for grilling.
  • Leafy vegetables: Things like spinach, arugula and lettuce don’t hold up very well to the intense heat of grilling but you can grill something like a head of romaine lettuce that’s been cut in half.
  • Root and tuber vegetables: These don’t grill quite as well as others because they are so starchy, firm and overly crisp. These include things like potatoes, carrots, beets, turnips and sweet potatoes. They can be grilled but you want to grill over a low heat for a longer period of time so they’ll end up tender by the time they’ve browned. A better option with these is to slice or dice, coat in oil and grill in foil in a single layer.
