Kitchen Equipment

• Knife and cutting board
• Tongs
• Basting brush (optional)
• Skewers or grill basket (optional for smaller vegetables)

How to Make

1. Start by heating the olive oil in a small pan over medium heat. Smash the garlic cloves and add them to the oil, letting them cook for about 5 minutes to infuse the oil with flavor. Remove and discard the garlic, then set the oil aside to cool to room temperature.
2. While the oil cools, wash and prep all the vegetables you want to grill. Brush the garlic-infused oil over the vegetables and season generously with salt and pepper.
3. Preheat your grill to 400°F over medium-high heat. Place the vegetables directly on the grill and cook for 5–10 minutes, turning as needed, until they’re tender and lightly charred.

Variations & Substitutions

Different Vegetables: While I love using bell peppers, yellow squash, and red onions, you can substitute them with the best vegetables you have available. Try zucchini, eggplant, cherry tomatoes, asparagus, or even white onions. Sweet potatoes need a bit more time on medium heat to cook through properly.

Marinade Options: Instead of a simple olive oil coating, try adding balsamic vinegar for a tangy twist. Fresh herbs like rosemary, thyme, or basil take these grilled veggies from good to amazing. You can also add a tasty dressing after grilling for extra flavor.

Cooking Method: No grill? No problem! You can make these in the oven at 425°F or use a stovetop grill pan on medium-high heat. The cooking time might vary slightly, but you’ll still get delicious results.

Protein Additions: Turn this into a complete meal by adding halloumi cheese, tofu, or even some grilled chicken to your vegetable skewers.

Storage

Let your grilled vegetables cool to room temperature before storing them in an airtight container in the refrigerator. They’ll stay fresh for up to 5 days, making them perfect for meal prep.

Leftover grilled vegetables are incredibly versatile. Toss them into salads, grain bowls, or pasta. You can also reheat them in a skillet over medium heat or enjoy them cold straight from the fridge.

I don’t recommend freezing these since the texture can become mushy when thawed. It’s better to grill only what you need or plan to use the leftovers within a few days.

Expert Tips

Keep in mind that cooking times can vary depending on the size of your vegetables and how hot your grill runs. Broccolini, asparagus, tomatoes, zucchini, and red onion usually take about 5 minutes, while sweet peppers may need closer to 7 minutes. Corn and mushrooms typically take around 10 minutes to become tender and nicely charred.

Since vegetables continue to cook a bit after coming off the grill, it’s best to pull them off just before they’re fully done to avoid overcooking.

Cut Uniformly: Make sure all your vegetables are cut into similar-sized pieces so they cook evenly. Larger pieces need more time, while smaller vegetables cook faster.

Don’t Skip the Oil: Coating your veggies with olive oil prevents sticking and helps them develop that beautiful char. It also helps the seasoning stick to both sides of the vegetables.

Preheat Your Grill: A hot grill is essential for getting those perfect grill marks. Aim for medium-high heat and make sure your grill grates are clean and well-oiled.

Give Them Space: Don’t overcrowd your grill basket or the vegetables will steam instead of getting that nice char. Work in batches if needed.

Watch the Heat: If your vegetables are charring too quickly, move them to a cooler part of the grill or reduce the heat to medium. You want them tender and caramelized, not burnt.

Season Generously: Vegetables need more seasoning than you think. Be generous with salt, pepper, and any other spices you’re using.

FAQ’s

What are the best vegetables for grilling?

Bell peppers, zucchini, yellow squash, red onions, portobello mushrooms, asparagus, and eggplant are all fantastic choices. Basically, anything sturdy enough to hold up to the heat works well.

Do I need to parboil vegetables before grilling?

For most vegetables, no. However, harder vegetables like sweet potatoes benefit from a quick parboil to speed up cooking time on the grill.

How do I prevent vegetables from sticking to the grill?

Use plenty of olive oil and make sure your grill grates are clean and preheated. A grill basket also helps prevent sticking and keeps smaller pieces from falling through.

Can I make a vegetable marinade ahead of time?

Absolutely! Mix your marinade and store it in the fridge. You can marinate your vegetables for 30 minutes to 2 hours before grilling for extra flavor.

Why are my grilled vegetables soggy?

This usually happens when the grill isn’t hot enough or the vegetables are crowded together. Make sure you’re cooking on a hot grill with enough space between pieces.

Can I use frozen vegetables?

Fresh vegetables work best for grilling. Frozen veggies contain too much moisture and won’t develop that nice char and smoky flavor you’re looking for.
