Ingredients You’ll need:

2 bell peppers (red, yellow, or green)
1 zucchini
1 cup cherry tomatoes
1 red onion
3 tablespoons olive oil
2 tablespoons balsamic vinegar
1 teaspoon dried oregano
Salt and pepper, to taste
Optional: Fresh basil or parsley for garnish

Ingredient Tips

Bell peppers become wonderfully sweet once grilled and add beautiful color.

Zucchini cooks quickly while staying tender and juicy.
Cherry tomatoes soften just enough to become extra flavorful without falling apart.
Red onion caramelizes beautifully, adding a mild sweetness.
Balsamic vinegar gives the marinade a slightly tangy flavor that pairs perfectly with grilled vegetables.

Easy Substitutions

Try yellow squash instead of zucchini.
Add mushrooms, asparagus, broccoli, or eggplant.
Italian seasoning works well if you don’t have oregano.
Fresh thyme or rosemary can replace dried herbs for a different flavor.

How to Make Grilled Veggies with Marinade for Summer

Making these Grilled Veggies with Marinade for Summer couldn’t be easier.

Prepare the marinade. In a medium bowl, whisk together the olive oil, balsamic vinegar, dried oregano, salt, and pepper until well combined.
Prepare the vegetables. Slice the bell peppers into strips, cut the zucchini into rounds, quarter the red onion, and halve or quarter the cherry tomatoes if desired.

Marinate the vegetables. Place the vegetables into a large bowl or zip-top bag. Pour the marinade over them and toss until everything is evenly coated. Let the vegetables marinate for at least 15 minutes.
Preheat the grill. Heat your grill to medium-high heat. If you’re using a grill basket, lightly oil it to prevent sticking.
Grill the vegetables. Arrange the vegetables on the grill or in the grill basket. Cook for about 10 minutes, turning occasionally until the vegetables are tender and have nice charred grill marks.

Serve. Transfer the vegetables to a serving platter and sprinkle with freshly chopped basil or parsley if you’d like. Serve immediately while they’re warm.

Helpful Tips

A few simple tricks can make grilled vegetables even better.

Cut the vegetables into similar-sized pieces so they cook evenly.

Don’t skip the marinating time. Even 15 minutes adds a lot of flavor.
Avoid overcrowding the grill. Giving the vegetables space helps them char instead of steam.
Keep an eye on smaller vegetables like tomatoes since they cook faster.

If something slips through the grill grates—and let’s be honest, it happens to all of us—a grill basket can save the day.
Taste before serving and add another pinch of salt if needed. Sometimes that’s the little finishing touch that makes everything pop.

Variations and Substitutions

This recipe is incredibly flexible.

Add mushrooms for an earthy flavor.
Include asparagus during peak spring and summer months.
Toss in broccoli florets for extra crunch.
Sprinkle grated Parmesan over the finished vegetables.
Add crumbled feta or goat cheese for a creamy finish.

Mix in a pinch of crushed red pepper flakes for gentle heat.
Use fresh rosemary, thyme, or Italian seasoning instead of oregano.
For a vegan and gluten-free side dish, simply prepare the recipe as written.

Storage and Reheating

Leftovers are just as delicious the next day.
Store cooled vegetables in an airtight container in the refrigerator for up to 4 days.
To freeze, place cooled vegetables in a freezer-safe container for up to 2 months. While they’ll still taste great, the texture may soften slightly after thawing.

For reheating:

Warm them in a skillet over medium heat for a few minutes.

Reheat on the grill for 2 to 3 minutes to bring back some smoky flavor.
Microwave in short 30-second intervals until heated through.

They’re also wonderful served cold in salads or tucked into sandwiches and wraps.
