Can I make these vegetables without a grill basket?

Yes! You can use skewers to make vegetable kebabs, or use a perforated grill pan. In a pinch, you can even create a makeshift basket using heavy-duty aluminum foil folded up at the edges. Just be careful with stirring to prevent vegetables from falling through the grates.

How do I keep the vegetables from sticking to the grill basket?

Make sure your grill basket is clean and well-oiled before adding vegetables. Additionally, tossing the vegetables thoroughly in oil before grilling creates a natural non-stick barrier. If you're still having issues, a quick spray of cooking oil on the basket before adding vegetables can help.

Can I make these vegetables in the oven instead?

Absolutely! Spread the seasoned vegetables on a large baking sheet and roast at 425°F for about 20-25 minutes, stirring halfway through. You won't get quite the same smoky flavor, but they'll still be delicious with nice caramelization.

Why did my vegetables turn out soggy instead of caramelized?

This usually happens when vegetables are overcrowded or when the grill temperature isn't high enough. Make sure your grill is properly preheated, don't overload your basket, and stir occasionally but not constantly. Also, ensure your vegetables are dry before seasoning and grilling.

Ingredients You’ll Need

Cherry or Grape Tomatoes: These little flavor bombs burst during cooking, releasing their juices and creating natural pockets of tangy sauce throughout the dish.
Olive Oil: Helps the seasonings stick and prevents vegetables from drying out on the grill. Use a good quality oil for the best flavor.
Salt and Pepper: The foundation of any good seasoning blend. Don’t skimp here!
Garlic Powder: Provides consistent garlic flavor without the risk of burning that comes with fresh garlic on the grill.

Flavor Profiles

Mediterranean: Add dried oregano and basil to the seasoning mix, then sprinkle with crumbled feta before serving.
Asian-Inspired: Replace some of the olive oil with sesame oil and add ginger powder to the seasonings. Finish with a drizzle of soy sauce and sesame seeds.
Spicy Kick: Add cayenne pepper or red pepper flakes to the seasoning blend, or finish with a drizzle of hot sauce.

Upgrades

Transform these vegetables into a complete meal by adding protein like grilled chicken, shrimp, or tofu. Alternatively, toss the finished vegetables with cooked pasta or grains for a hearty main dish.

How to Make the Best Grilled Vegetables

Step 1: Prepare the Vegetables

Cut zucchini into 1/4-inch medallions, and chunk the bell peppers and red onion into bite-sized pieces about 1-inch across. Quarter larger mushrooms or halve smaller ones. Leave cherry tomatoes whole—they’ll burst beautifully during cooking, creating pockets of flavorful juice.

Step 2: Preheat Your Grill

Get your outdoor grill fired up to medium-high heat (around 400°F). This temperature provides the perfect balance—hot enough to get good caramelization without burning the vegetables.

Step 3: Season the Vegetables

In a large mixing bowl, combine all your cut vegetables. Drizzle with olive oil and sprinkle with salt, garlic powder, onion powder, and black pepper. Use your hands or large spoons to toss everything until each piece is evenly coated with oil and seasonings.

Step 4: Grill to Perfection

Transfer the seasoned vegetables to a grill basket—this essential tool prevents smaller pieces from falling through the grates. Place the basket on the preheated grill and cook for 12-15 minutes, stirring every 2-3 minutes to ensure even cooking. You’ll know they’re done when the vegetables are tender with light charring and the tomatoes start to burst.

Step 5: Final Seasoning and Serve

Once cooked, give the vegetables a taste and adjust seasonings if needed. A little extra salt and pepper can really make the flavors pop. Serve immediately while still hot and aromatic.

Pro Tips for Making the Recipe

Cut vegetables to similar sizes for even cooking—this is crucial for getting everything done at the same time.
Don’t overcrowd the grill basket. If necessary, cook in batches rather than piling vegetables too high, which can lead to steaming instead of grilling.
Keep the lid closed on your grill when not stirring to maintain temperature and create a more oven-like environment.
Add delicate herbs like basil or cilantro after grilling, not before, as they’ll burn on the high heat.
Let your grill basket heat up before adding vegetables to get better initial searing and caramelization.
Pat vegetables dry after washing to ensure they’ll sear properly instead of steam.

How to Serve

Main Course Pairings

These grilled vegetables pair beautifully with grilled proteins like chicken, steak, or fish. They’re particularly wonderful alongside a simply seasoned protein that won’t compete with their flavors.

As Part of a Spread

Include these colorful grilled vegetables as part of a larger barbecue spread or buffet. They’re delicious warm, room temperature, or even cold, making them perfect for outdoor gatherings.

Transformations

Toss with cooked pasta and a splash of olive oil for a simple pasta primavera
Layer on toasted bread with goat cheese for an elevated bruschetta
Mix with quinoa or couscous for a hearty grain bowl
Use as a filling for omelets or frittatas the next morning

Make Ahead and Storage

Storing Leftovers

Store cooled grilled vegetables in an airtight container in the refrigerator for up to 4 days. The flavors actually develop and improve overnight, making this a perfect make-ahead dish.

Freezing

While you can freeze these grilled vegetables, they’ll lose some of their texture upon thawing. If freezing, store in an airtight container for up to 2 months. They work best in cooked applications like soups or sauces after freezing.

Reheating

For best results, reheat in a skillet over medium heat just until warmed through. Microwave reheating works in a pinch but may make the vegetables softer. A quick trip under the broiler can help restore some of their char and texture.
