Grilled Vegetables Recipe With Fresh Herb Dressing

These easy grilled vegetables are one of my favorite summer side dishes because they’re colorful, easy to make, and pair well with pretty much anything coming off the grill. The trickiest part is getting them all to cook evenly, but this recipe makes it simple. 

I use a mix of fresh veggies, a simple seasoning blend, and a bright herb dressing that gets brushed on after grilling for bonus flavor. The result is tender, smoky vegetables with plenty of color and texture, and a savory addition to everything from weeknight dinners to cookouts.

Key Ingredients

Here’s what you’ll need to make these grilled vegetables:

Vegetables

• Red bell peppers: They’re sweet, colorful, and one of my favorite vegetables for grilling because they hold their shape when they get tender.
• Carrots: Grilled carrots add natural sweetness and a little crunch. Slice them lengthwise so they cook more evenly on the grill.
• Yellow squash: This summer squash caramelizes slightly when lightly grilled. Zucchini is an easy substitute and cooks in about the same amount of time.
• Broccoli: Large florets of grilled broccoli develop these delicious, crispy edges while staying tender in the center.
• Eggplant: Eggplant gets creamy and smoky on the grill. Make sure to slice it thick enough so it doesn’t fall apart.
• Cabbage: Grilling transforms cabbage into a sweeter, more flavorful vegetable with crispy edges.
• Red onion: Red onion softens and caramelizes beautifully on the grill. Sweet onions or yellow onions also work well.

One of the best things about this recipe is how flexible it is! Brussels sprouts, mushrooms, cauliflower, green beans, and asparagus are all easy-to-grill vegetables. Just keep in mind that smaller or more delicate vegetables may cook faster. If you want to try sweet potatoes or other root vegetables, I suggest pre-cooking them to avoid long grill times.

Seasonings & Herb Dressing

• Olive oil: I like extra-virgin olive oil both for coating the vegetables before grilling and as the base for the herb dressing.
• Kosher salt and black pepper: These simple seasonings help bring out the vegetables’ natural flavors. A little garlic powder can add a roasty flavor if you’d like.
• Fresh dill, mint, and chives: This fresh herb combination adds brightness and balances the smoky grilled flavor. I keep coming back to this combo, but parsley, basil, thyme, oregano, cilantro, green onions, or even an Italian seasoning mix can all work.
• Red wine vinegar: Adds acidity and tanginess to the dressing. Balsamic vinegar can work, but the end result will be sweeter and more syrupy. 
• Fresh lime juice: Brightens everything and adds a fresh, summery flavor to the dressing. Lemon juice is an easy substitute.

How to Make This Grilled Vegetables Recipe

This recipe is simple, but a few small details make a big difference in getting that perfect mix of smoky flavor, tender veggies, and lightly charred edges. Here’s how to grill vegetables, step-by-step.

Preheat the grill to about 400ºF and make sure the grates are clean so the vegetables don’t stick. While the grill heats, prep all the vegetables and toss them with olive oil, salt, and pepper until they’re evenly seasoned. Let them rest for about 15 minutes.

Think of this as a light vegetable marinade for grilling. It’s not a traditional marinade since there’s no acid, but it helps them season evenly and improves their browning on the grill.

While the vegetables rest, whisk together the olive oil, fresh herbs, vinegar, lime juice, and salt. You’ll brush it on at the end, so the flavors stay fresh and bright instead of cooking off on the grill. 

Pro tip: Let the dressing sit for a bit to allow the herbs to infuse the oil with flavor.

Place the vegetables directly on the grill grates over medium-high heat. This is how I get those signature grill marks and smoky flavor. Most vegetables need about 5-8 minutes before the first flip, depending on the vegetable and its thickness. When you see clear grill marks, and they release easily from the grill without sticking, flip and continue cooking for another 5-8 minutes.

Thicker vegetables like carrots may take longer to cook, while softer vegetables like squash will finish faster. I like to pull each vegetable off as it becomes tender with browned edges, so nothing gets overcooked.

Once everything is off the grill, I transfer the vegetables to a serving platter and brush them with the herb dressing. The heat helps the dressing soak in slightly while still keeping the herbs fresh and vibrant.

These simple tricks make a big difference when it comes to getting evenly cooked, flavorful grilled vegetables with the perfect char:

• Preheat and clean your grill. I always start with a hot, clean grill so the vegetables don’t stick and those grill marks actually form. If the grates are dirty or not hot enough, the vegetables tend to tear or steam instead of sear.
• Cut vegetables evenly. Try to keep pieces similar in size so they cook at the same rate. Slice thicker vegetables like carrots and eggplant a bit thinner. Softer veggies like squash can be slightly thicker.
• Don’t overcrowd the grill. Give the vegetables space so the heat can circulate. If you pack them too tightly, they’ll steam instead of getting that smoky, caramelized flavor.
• Embrace uneven charring. It’s totally fine if some vegetables are more charred on one side than the other. Just toss everything together before serving so the flavors and textures mix evenly.

Grill Times at a Glance

Here’s a quick guide for how long the vegetables in this recipe typically take on a 400ºF grill:

• Bell peppers: 10-15 minutes total
• Carrots: 12-18 minutes total
• Yellow squash: 8-12 minutes total
• Broccoli: 10-12 minutes total
• Eggplant: 10-14 minutes total
• Cabbage: 10-15 minutes total
• Red onion: 8-12 minutes total

Keep in mind that grill heat, thickness, and the level of char you like will all affect the timing. I always use visual cues like browning edges and fork-tender texture rather than relying on my timer alone.

Serving Suggestions

Grilled vegetables are one of those easy summer sides that go with almost everything. They’re great fresh off the grill, but I also love them for meal prep and adding them to quick meals throughout the week. 

Here are some of my favorite ways to serve them:

Store any leftover grilled vegetables in an airtight container in the fridge for up to 5 days. To reheat, I recommend the oven or broiler for a few minutes to keep them nice and crispy. Reheating them in the microwave can make them turn soggy.

Can I use a grill basket for vegetables?

You don’t need one for this recipe, but a grill basket can work well for smaller or more delicate vegetables like zucchini, mushrooms, or broccoli florets. It helps prevent anything from falling through the grates while still allowing you to get that smoky flavor. Just make sure to preheat the basket so the vegetables still get a good sear instead of steaming.

How can I prevent vegetables from sticking to the grill?

A hot, clean grill is the most important step to keep your vegetables from sticking. I always preheat the grill and make sure the grates are scrubbed clean before adding any vegetables. Coating the vegetables in olive oil also helps create a barrier, allowing them to release more easily. 

What are some common mistakes to avoid when grilling vegetables?

The biggest mistakes to avoid at the grill are not cutting vegetables evenly, overcrowding the grill, and not preheating long enough. Uneven pieces lead to uneven cooking, and overcrowding causes steaming instead of charring. A cooler grill makes it harder to get those crisp edges and grill marks.
