This might look like a simple idea rather than a strict recipe, but my tray of Crowd-Pleasing Grilled Vegetables is the most requested dish at our family gatherings. It reliably satisfies a crowd every time.
I use the straightforward vegetables listed here, but summer abundance invites variation. Add yellow squash, radicchio, or other seasonal finds. I once discovered exceptional red onions at a farmer’s market — sweet Vidalias work beautifully too.
When selecting and preparing vegetables, keep these tips in mind:
- Choose hearty pieces — the more substantial, the better.
- Select thicker asparagus stalks for a satisfying texture.
- Slice zucchini and eggplant on the diagonal for meaty portions.
- Grill large portabellas whole and slice them for the platter; baby portabellas are fine but require extra care on the grate.
I prefer grilling directly on the grate, but a grill basket is handy if you worry about losing smaller pieces. After cleaning and slicing, coat all sides of the vegetables with olive oil and season with coarse kosher salt and freshly ground black pepper.

Gather it all up…
I like to load the prepped vegetables into a large roasting pan or onto rimmed baking sheets for easy transport to the grill. For brushing, mix roughly two parts extra virgin olive oil with one part good balsamic vinegar; adjust quantities to match the volume of vegetables. Don’t forget a basting brush, extra salt and pepper, and long-handled tongs.

No overcooked veggies here…
- Brush vegetables lightly with the oil-and-balsamic mix while grilling.
- Season with salt and pepper to taste.
- Aim for a pleasant char on the outside while keeping some bite inside—avoid overcooking.
- Grill times vary by vegetable; pay attention and stay near the grill. Most items finish within minutes.


No stacking allowed…
- Transfer each finished variety to a clean baking sheet and arrange in a single layer, overlapping slightly if needed.
- Avoid overcrowding so the vegetables stay crisp rather than soggy.
- You can grill the vegetables earlier in the day or even the day before; once cooled, cover loosely and refrigerate until serving.
For serving, I often use a large ceramic platter or a lighter wood-and-plastic tray for transport. Line the bottom with parchment paper to prevent drips and add a layer of curly lettuce for an attractive base—don’t skip the lettuce; it enhances presentation and helps hold the vegetables in place.



Time to build your very own tray of Crowd-Pleasing Grilled Vegetables…
Start at the outer corners and work toward the center, arranging the grilled vegetables artfully on the lettuce. Since this is often part of a buffet, consider adding complementary ingredients:
- Fresh mozzarella slices
- Shaved Parmesan
- Sun-dried tomatoes or sliced fresh heirloom tomatoes
- Whatever your guests will enjoy—keep it seasonal and simple.

Serve warm or at room temperature…
These grilled vegetables are excellent as a side or enjoyed on their own. They also make a fantastic vegetarian sandwich when served with crusty artisan rolls.

Now that you’re a veggie grill-master…
If you happen to have leftovers, transform them into a Grilled Veggie Pasta Salad or toss them with pasta, fresh herbs, and a little extra balsamic for a quick, satisfying meal.

Mix 2 parts extra virgin olive oil with 1 part balsamic vinegar in a cup for brushing while grilling.
