End-of-Summer Vegetable Grill Roundup

Start by deciding direct versus indirect heat. Direct heat (hot grates, 450–550°F) is where you get quick sear and char—good for thick zucchini planks, rounds, peppers and halved peaches. Indirect heat (coals or burners off under one side, grate at 350–400°F) lets dense items like whole eggplants or foil-wrapped corn soften through without burning. For mixed grills arrange items by cook time and move them between zones rather than trying to manage everything over a single flame.

Treat the grate and the veg the same way: clean, oil the grate and lightly oil the vegetables. Wipe oil on slices with a paper towel rather than tossing wet veg in oil; that prevents drips and flare-ups. Salt right before or just after grilling for delicate items; salting too early draws water and can make zucchini soggy. Doneness cues matter more than a strict timer: zucchini should be tender with defined grill marks, peppers should collapse and blister, and tomatoes will show softened flesh and glossy juices.

Keep a quick, flexible marinade on hand: 3 parts neutral oil to 1 part acid (lemon or vinegar), a minced garlic clove, a teaspoon of mustard or honey for balance, and a tablespoon chopped herbs per cup. Marinate firm veg 15–30 minutes; fragile items a few minutes. Use this timing chart as a guide for mixed grilling: zucchini planks 3–5 minutes per side, rounds 2–3; peppers 6–10 minutes total; corn 10–15 minutes husk-off; eggplant steaks 4–6 minutes per side; halved peaches 2–3 minutes per side. Recipes in this section—Grilled Vegetable Antipasto, Grilled Vegetable Kabobs with Balsamic Glaze and Feta, and Citrus Herb Veg Tofu Marinade—show these basics applied at a meal scale.

There are three practical ways to grill corn, each with its trade-offs. In-husk grilling steams the kernels while adding subtle smoke; leave the outer husks intact and soak the ears 10–15 minutes if you worry about flare-ups. H usk-off, direct-over-flame grilling gives fast char and the greatest caramelization—expect 10–15 minutes total, turning every 2–3 minutes until kernels darken in spots. Foil-wrapped, indirect grilling is gentler and reliable for larger gatherings, taking longer but reducing char risk.

Look for doneness by feeling the kernels through the husk if using husk-on—the ear should feel plump and warm—or by testing one kernel for a sweet, slightly crisp bite. Two finishing ideas that work almost every time are chili-lime butter—softened butter whipped with lime zest, a pinch of chili powder and salt—and a herbed vinaigrette of parsley, lemon, olive oil and a little sherry vinegar. Both cut through the corn’s natural sweetness and add lift.

Grilled corn is at home as a salad element or a taco topper: use kernels in a charred corn salad with cotija and lime, or pile them on tacos with crema and cilantro. Pair corn with proteins like grilled shrimp (shrimp’s quick, high-heat cooking echoes the corn’s char) or roast chicken (softer meat and pan juices play well with sweet corn). Try the Smoked Elote-Style Corn with Chili-Lime Butter, Grilled Corn Dip, or Charred Corn Salad for inspiration.

How you cut zucchini changes everything. Planks (long, 1/3–1/2-inch thick) grill like steaks—good for a centerpiece where you want chew and sear. Ribbons (use a peeler) are quick to blister and fold into salads or roll-ups. Rounds and chunks are best for skewers. Thicker cuts resist overcooking; thin slices vanish into soft nothingness. Lightly salt thicker cuts after grilling or just before if you’ll serve immediately; salting far ahead draws water and invites sogginess.

Timing is brief: planks generally need 3–5 minutes per side over medium-high heat, rounds about 2–3 minutes per side. Flip once or twice—more flips tear delicate ribbons. Oiling matters: brush oil directly on each piece and wipe off excess rather than dunking. Two quick marinades to keep handy are garlic-herb (oil, minced garlic, chopped parsley and oregano) and lemon-olive oil (olive oil, lemon zest and juice, a touch of honey). Both highlight the squash’s mild sweetness without masking char.

Zucchini makes a satisfying main when paired with grains or cheese—try it atop a warm farro bowl or grilled onto flatbread with ricotta. For protein pairings, think goat-cheese–stuffed chicken for an herb-forward roast or simply grilled fish for a lighter meal. See Grilled Zucchini Ribbons and Grilled Zucchini Roll-Ups for concrete ideas you can assemble ahead and finish on the grill.

Eggplant soaks oil and smoke; treat it thoughtfully. For a meaty, plated main, cut thick steaks (about 3/4-inch). For spreads and dips, halve small globe eggplants and roast until fully collapsed. Salting is optional: a short salt (10–20 minutes) can help draw out bitter juices and reduce absorbency, but it also removes some flesh water that adds silkiness—so salt when you need structure, skip it when you want creamier results.

Grill at medium-high for steaks—about 4–6 minutes per side until the flesh gives under a fork and edges are deeply charred. Whole or halved small eggplants cook by indirect heat for 20–30 minutes until the skin is blackened and the interior is very soft. Texture cues are key: a done eggplant will feel soft and almost jammy; undercooked eggplant is spongy and dry.

Finish eggplant with bold, smoky sauces: a tahini-yogurt drizzle brightens grilled baba ganoush, while a smoky tomato ragu turns slices into a saucy main. Uses range from an eggplant steak plated with herbs to a spread for sandwiches and mezze. Pair grilled eggplant with robust proteins like lamb chops or seared tuna, and consult Grilled Eggplant Baba Ganoush and the Make-Ahead Grilled Summer Vegetable Gratin for ways to make eggplant the star or the supporting texture in a composed dish.

Peppers take two common approaches: blistering over very high heat for bright, lightly charred skins, or a slower roast for deeply softened flesh and sweeter flavor. Blistering suits small peppers like shishito (1–2 minutes total over high heat) while bell peppers need 6–10 minutes total, turning until the flesh collapses and black patches form. Decide whether to peel: for silky salads or stuffed peppers, char until skins blacken and steam in a covered bowl—then peel. If you like the rustic bite, leave the skin.

After grilling, prepare peppers for stuffing or slicing while still warm; the flesh separates from membranes more easily. Quick dressings that finish grilled peppers include a garlicky vinaigrette (olive oil, red wine vinegar, minced garlic) and a balsamic glaze for a sweeter counterpoint. Fillings can be as simple as herbed goat cheese or as substantial as a grain-and-cheese stuffing; a charred pepper relish makes a great topping for sandwiches and crostini.

Peppers pair naturally with sausages that share smoky fat, or grilled fish for a lighter contrast. Recipes to try: Charred Shishito and Bell Pepper Skewers with Sesame-Garlic Sauce, Smoky Grilled Stuffed Mini Peppers with Herbed Goat Cheese, and Chimichurri Steak Kabobs with Grilled Peppers, which demonstrate blistering, stuffing and robust pairings.

Tomatoes reward high heat but require quick, confident work. Choose firm-ripe beefsteaks for halving and grilling, or use firm cherry tomatoes for blistering—both concentrate sweetness under the heat. Halve larger tomatoes and season simply; cherry tomatoes can be skewered or cooked loose in a cast-iron skillet so they blister without rolling into the fire.

High heat is the rule: count on 2–4 minutes per side depending on size. Watch for softened flesh, glossy juices and a slight give when pressed; avoid cooking so long that the flesh collapses into puddles. If juices accumulate, move the tomatoes to a cooler part of the grill briefly to let their skins set without losing structure.

Quick transformations broaden uses: charred tomato salsa mixes blistered cherry tomatoes with onion, cilantro and lime; a warm tomato vinaigrette finishes grilled steak or tossed grain salads. Grilled tomatoes change salads and sandwiches by adding smoky sweetness—try them on charred crostini or in a warm farro salad. Pair with grilled steak or roasted chicken for satisfying contrasts. For practical ideas, see Charred Tomato Bruschetta, Classic Warm Farro & Roasted Tomato Salad, and the cedar-plank swordfish recipe with warm olive-tomato tapenade.

Peaches go from firm to caramel in minutes, so pick fruit that’s slightly firm but aromatic. Halve and pit them, then lightly oil the cut side; a brief dusting of sugar helps with caramel if the peach is underripe. Grill over direct heat for 2–3 minutes per side—watch the sugars, which can flame on very hot grates, and move peaches away from direct flames if flare-ups occur.

To prevent sticking, oil the grill and the peach flesh rather than relying on sprays that pool. Use a thin metal spatula to flip carefully. Finished peaches can be treated sweet or savory: drizzle with honey or a balsamic reduction and pair with mascarpone or serve alongside burrata for a savory-sweet contrast. Prosciutto is a classic salty foil, or frame peaches with bright herbs and lemon for salads.

Peaches work as dessert—grilled peach angel food cake is an obvious sweet—or as a savory side with grilled proteins. Pair them with pork chops or grilled chicken where the fruit’s caramel and acidity balance fattier meat. For bright composed plates, try Grilled Peach Burrata Salad or Halloumi and Peach Skewers for a cheese-forward option that doubles as appetizer or main.
