The single most important rule: dress the vegetables hot. A vinaigrette applied to cold grilled vegetables sits on the surface and tastes separately of oil and acid. The same vinaigrette applied to vegetables straight off the grill is absorbed into the flesh, and the lemon and vinegar brighten and amplify the char rather than competing with it. The second key: do not crowd the grill. Vegetables crowded together lower the temperature of the grate and begin to steam in each other's moisture — the result is pale, soft, boiled-tasting vegetables with no char. Work in small batches, leave space between each piece, and trust that the grill needs time to build the char marks that give grilled vegetables their character.
Grilled vegetables are better at room temperature than refrigerator-cold. If making ahead, grill and dress up to 3 hours in advance, cover loosely, and leave at room temperature. They are even better the next day after marinating overnight in the dressing — the char softens slightly and the flavours meld. This makes grilled vegetable platters ideal for parties: make them the morning of, refrigerate, and bring to room temperature 30 minutes before serving. For a more substantial main: serve with warm flatbread, hummus, and labneh; or over freekeh or pearl couscous; or alongside grilled halloumi.
Grilled Vegetable Platter
By Sergei Martynov
A grilled vegetable platter is the most underrated item at any barbecue — and the most versatile. Where meat requires precise temperature control and resting times, vegetables are forgiving: they tell you when they are done by releasing from the grates, and they improve with a few minutes of rest, during which the heat equalises and the marinade or dressing soaks in. The technique is the same across all vegetables: oil them generously (oil on the vegetable, not just the grate), grill on medium-high direct heat for the time each vegetable needs, and dress them hot — a vinaigrette applied to hot vegetables is absorbed rather than sitting on the surface. The key to a beautiful platter is timing: eggplant and peppers need the most time; zucchini and asparagus need the least. The trick is to work in sequence, pulling each vegetable as it finishes, and to arrange everything on one platter together so the final dish is warm and accessible.

How to make it
Instructions
- 1
Prepare the eggplant and toss all vegetables. Eggplant contains moisture that can cause steaming rather than searing on the grill. To prevent this: slice into 1 cm rounds, salt both sides, and leave in a colander for 20 minutes. Pat completely dry with paper towels. Meanwhile, prepare all other vegetables. Combine the olive oil, minced garlic, salt, pepper, and oregano in a large bowl. Add all the prepared vegetables and toss thoroughly to coat every surface. The oil on the vegetable surface — not the grill grate — is what prevents sticking and promotes the Maillard reaction.

Set up a two-zone grill. For charcoal: build a moderate fire concentrated on one side of the grill (medium-high direct, approximately 220°C/430°F). For gas: set one side to medium-high, leave one side lower. The two zones are essential: the high-heat side builds char marks and crust; the lower side finishes vegetables through without burning them. Oil the grates with a paper towel dipped in oil. The grill is ready when a few drops of water evaporate instantly on contact.

Grill in sequence by cooking time. Work in batches by cooking time — do not crowd the grill or the vegetables will steam. Start with the longest-cooking items. Eggplant rounds: 4 to 5 minutes per side over direct heat until deeply golden and soft through the centre. Bell peppers: 4 to 5 minutes per side skin-side down until blistered. Red onion: 4 minutes per side over medium-direct heat. Mushrooms: 3 to 4 minutes per side. Zucchini: 2 to 3 minutes per side. Asparagus: 2 minutes per side, rolling occasionally. Cherry tomatoes: 2 to 3 minutes without moving until blistered. Transfer each vegetable to a baking sheet or platter as it finishes — do not stack hot vegetables on top of each other.

Make the dressing and finish hot. While the last vegetables are grilling, whisk together the dressing olive oil, lemon juice, red wine vinegar, sumac (or smoked paprika), and a pinch of salt. The key insight: dress the vegetables while still hot. Hot vegetables absorb the dressing into their flesh rather than just sitting in it on the surface, and the acidity of the lemon and vinegar brightens the charred flavour. Toss or drizzle over the hot grilled vegetables. Leave to rest for 5 to 10 minutes before plating — this allows the dressing to penetrate and the textures to settle.
- 5
Arrange the platter. On a large wooden board or deep platter, arrange the grilled vegetables in loose sections by type and colour — do not mix them into a mush. Alternate colours: dark eggplant next to bright peppers, green zucchini next to charred asparagus. Scatter the torn fresh herbs over the top. Crumble the feta across the centre if using. Drizzle a final thread of good olive oil over everything. Serve immediately or at room temperature within 1 hour — grilled vegetables are excellent warm but genuinely taste better as the dressing soaks in over 15 to 20 minutes.
Frequently Asked Questions
Why do grilled vegetables stick to the grill and how do you prevent it?
Vegetables stick for the same reason fish and meat stick: insufficient heat, insufficient oil on the surface, and moving them before they have formed a sear crust. The solution is the same for all three. First, oil the vegetable itself generously — oil on the food, not just on the grate, ensures even coverage. Second, make sure the grill is fully preheated and the grates are hot (a drop of water should evaporate instantly). Third, do not try to move a vegetable immediately after placing it — let it cook undisturbed until a char crust forms, which naturally releases it from the grate. A vegetable that resists lifting is not yet ready to flip.
What is the best cut for each vegetable?
The cut determines how much surface area contacts the grill (more surface = more char) and how evenly the vegetable cooks (uniform thickness = even cooking). Eggplant: 1 cm rounds — thin enough to cook through without burning the exterior, thick enough to hold together on the grill. Zucchini: halved lengthwise or 1 cm diagonal planks — lengthwise gives maximum char surface. Bell peppers: quartered — large flat pieces lay flat on the grates. Red onion: 1 cm rounds with a toothpick to hold rings together. Asparagus: whole spears with ends snapped off. Mushrooms: halved if large, whole if small — stem-side down first. Cherry tomatoes: whole or halved, grilled cut-side down.
Can the platter be made ahead of time?
Yes — this is one of the best features of a grilled vegetable platter. Grilled vegetables improve significantly with 15 to 30 minutes of resting in the dressing, and they are genuinely excellent at room temperature or even slightly warm, unlike most hot dishes that deteriorate once cold. Grill and dress up to 3 hours ahead and leave covered at room temperature. They can be refrigerated for up to 2 days; remove from the refrigerator 30 minutes before serving to come to room temperature, and add fresh herbs immediately before presenting.
What other vegetables work well on the grill?
Almost any vegetable can be grilled given the right preparation. Corn on the cob: grill in the husk for 15 minutes total, turning occasionally, then peel and serve with herb butter — this is covered in its own recipe. Romaine lettuce: halved lengthwise, brushed with oil, grilled cut-side down for 2 minutes until lightly charred — served with Caesar dressing. Fennel: sliced into 1 cm slabs, grilled 4 minutes per side — excellent with citrus. Broccoli: cut into large florets, tossed in oil, 3 to 4 minutes per side over medium-high heat. Leeks: halved lengthwise, brushed generously with oil, grilled 5 to 6 minutes until tender. Avocado: halved and pitted, grilled cut-side down 3 to 4 minutes, served with lime.
What dressings and toppings go well with grilled vegetables?
The key principle is acidity: grilled vegetables benefit enormously from an acidic element that lifts and brightens the charred flavour. Classic options in order of intensity: Ladolemono (Greek olive oil and lemon, perhaps with capers and herbs — included in this recipe); Salsa verde (Italian herb sauce — purée of parsley, capers, anchovies, garlic, and olive oil); Balsamic glaze drizzled over the arranged platter; Tahini sauce thinned with lemon juice; Romesco (roasted pepper and almond sauce); Whipped feta (feta blitzed with olive oil and lemon until smooth). For toppings: crumbled feta (included here), toasted pine nuts, pomegranate seeds, or shaved Parmesan all add texture and richness.
