I like to grill all year, but especially during the summer when there’s so much fresh produce available. We like going to the farmer’s market and picking out all kinds of fresh veggies to cook on the grill.

Grilled vegetables are easy to do, but there are some tips and tricks to making them, so they turn out perfectly cooked. How long to grill vegetables will depend on what kind you want to cook. Usually, we do a mix of veggies, so knowing the approximate cooking time for each and cooking them based on that ensures they will be fully cooked instead of burned or undercooked.

For the best grilled vegetables, you want to start with denser ones because they will need more time. Lighter veggies with a higher water content will need less time than meatier ones.

For this grilled vegetable recipe, I’ve chosen several veggies that taste delicious together but also need to be cooked in a specific order so you can see how this works. It’s not an exact science, but keeping these tips in mind will help you cook them just long enough.

How to Grill Vegetables

Coat the grill grates with cooking spray and heat the grill to medium-high heat.

The vegetables all having different grilling times, so I like to get them all prepped first. That way, when it’s time to put them on the grill, they are ready to go.

  • Brush the sliced onions and bell peppers with olive oil.
  • Place the mushrooms on grill skillets and coat them with cooking spray.
  • Coat the zucchini and asparagus with cooking spray.

I like to put the bell peppers and onions on the grill first because they take the longest to cook. Place them directly on the grill grates and cook them for four to five minutes or until they’ve developed a nice char. Turn them and cook them for four to five minutes on the other side.

Place the mushrooms and asparagus on the grill and cook them for two minutes. Add the zucchini and continue grilling the vegetables for four minutes, turning them as they cook, so they don’t burn.

The vegetables are done when they have some char and are tender. The zucchini should still be a little firm and not mushy.

Remove them from the grill and arrange them on a serving platter. Season them with a few pinches of salt and pepper or more to taste.

Recipe Tips and Variations for Grilled Vegetables

Serve them as a side dish with all kinds of proteins. They pair well with grilled steak, pork chops, chicken, fish, and sausages.

Sometimes I serve them as a main dish with cooked rice or buttered noodles. The mushrooms have a meaty texture that is very filling.

You can also use them to make a salad. Serve them on top of chopped fresh greens with your favorite dressing. You could also add some sliced chicken or steak.

I love this combination of vegetables, but you can also add other veggies you like. Cauliflower, broccoli, grape tomatoes, yellow squash, and different peppers like poblano or green, yellow, or orange bell peppers are good choices.

Sometimes I just grill the mushrooms and onions and use them as a topping for steak, which is delicious.

If you don’t have the grill skillets for the mushrooms, you can use a grill basket or thread the mushrooms onto skewers and grill them that way.

Grilled vegetables will keep well in the refrigerator for two to three days. They are delicious cold, or you can reheat them.

Grilling vegetables is one of my favorite cooking methods. It enhances the flavors of the vegetables and gives them a little smoky flavor. Plus, it’s easy! So, pick up some fresh produce and give this easy recipe a try.
