A rainbow of tender grilled vegetables with a slight char and bit of crispiness is the best side dish for cookouts or grilled meats. And they’re so easy to make!

Why this recipe works

Bell peppers, red onion, broccoli, zucchini, and baby bella mushrooms come together on the grill quickly leaving you with crispy grill marks and maximum flavor. Grilling vegetables brings forth their natural sweetness while taking them from crunchy to tender in a matter of 15 minutes. It’s time to switch up the regular grilled corn on the cob to include a little variety in your veggie side dishes!

It doesn’t take much to grill vegetables, other than a bit of olive oil and an array fresh veggies. We simply slice and cut the veggies, toss them in olive oil and seasonings, then place them directly on the grill. However, you can easily use this recipe to make skewered vegetables as well!

Ingredient Info and Substitution Suggestions

VEGETABLES – We are using yellow and orange bell peppers (but you can also use red or green), red onion, broccoli, zucchini, and baby bella mushrooms. You will want your vegetables to be fairly uniform in size so they all cook evenly on the grill. If you’ve cut your veggies a little too small that they might fall through the grill grate, place them on a skewer to cook or put them in a grill basket. You can use other vegetables like cauliflower, Brussels sprouts, asparagus, eggplant, tomatoes, potatoes, and peppers. The heartier the vegetable you use (or the thicker cut they are), the longer they will need on the grill.

EXPERT TIP – We will be placing the vegetables directly on the grill grates, however, if you prefer you can use a grill basket or thread them onto skewers. We like placing them directly on the grates to get the best grill marks and so they are evenly cooked.
Whisk together olive oil, Italian seasoning, and garlic salt.
In a large bowl, pour seasoning mixture over the vegetables and toss with gloved hands until evenly coated.
Carefully pour vegetables onto the grill. Spread them out in an even layer and close lid. Allow to cook for 8-10 minutes. Use tongs to turn the vegetables over and cook for about 5 more minutes, or longer if you prefer them more tender.
