A grilled vegetable platter is one of the most underrated things you can put on a summer table. When vegetables hit a hot grill, their sugars caramelize, their moisture concentrates. They develop a smoky depth that raw or roasted versions simply cannot match. Add thick slabs of halloumi, the Cypriot cheese that holds its shape on a grill grate. You have a vegetarian main course that nobody at the table will call a side dish. This works for backyard cookouts, dinner parties, or a simple weeknight meal when you want to eat well without much fuss. Big difference. The key to a great platter is managing cook times.
Denser vegetables like onion wedges and portobello mushrooms go on first, while asparagus and peppers need less time. Cut everything to a similar thickness so pieces cook evenly, and brush generously with garlic-infused olive oil before grilling. A keeper. Halloumi has a high melting point, so it sears and chars on the outside while staying firm. One important note: eat it hot. Cold halloumi turns stiff and rubbery, which is a letdown after all that grill work. A drizzle of balsamic vinegar, some torn basil, and fresh lemon over the whole platter ties everything together. This is a make-it-once, memorize-the-method situation rather than a strict recipe.
Oil and Season Everything Before Grilling
Whisk together the olive oil, minced garlic, salt, and pepper, then brush the mixture generously over all the vegetables and halloumi slices. Cut your zucchini, squash, peppers, and onion into similar thicknesses so they cook evenly. Thin slices char too fast and thick pieces stay raw inside. Trim the asparagus and clean the portobello caps.
Grill the Vegetables in Order of Cook Time
Start with the onion rounds and portobello caps, which need 5 to 6 minutes per side. Add the bell peppers, zucchini, and squash next at 3 to 4 minutes per side. The asparagus goes on last, needing just 2 to 3 minutes while rolling frequently. Grill the halloumi slabs 2 to 3 minutes per side until golden grill marks appear. Halloumi has a high melting point so it holds its shape, but eat it hot because it turns rubbery as it cools.
Arrange the Platter with Balsamic and Fresh Herbs
Transfer everything to a large platter as it comes off the grill. Drizzle balsamic vinegar over the top, then scatter torn basil and chopped oregano across the spread. Serve with lemon wedges on the side. The char and smoke from the grill concentrate the vegetable flavors in a way that raw produce never achieves, and the halloumi adds enough substance to make this a full main course.

Grilled Vegetable Platter with Halloumi
- Total Time: 30 minutes
- Yield: 4 servings
Description
Grilled vegetables are the side dish that steals the show when done right — charred, smoky, and concentrated in flavor in a way raw vegetables never achieve. Add thick slabs of halloumi cheese that sear on the grill without melting, and you have a vegetarian main course that meat eaters will reach for too. The key is cutting everything the right thickness and not crowding the grill.
Ingredients
- 8 ounces halloumi cheese, sliced into 1/2-inch slabs
- 2 medium zucchini, sliced lengthwise into 1/3-inch planks
- 2 medium yellow squash, sliced lengthwise into 1/3-inch planks
- 1 large red bell pepper, quartered and seeded
- 1 large yellow bell pepper, quartered and seeded
- 1 bunch asparagus, trimmed
- 1 large red onion, cut into 1/2-inch rounds
- 2 portobello mushroom caps
- 1/4 cup olive oil
- 3 cloves garlic, minced
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons balsamic vinegar
- 2 tablespoons fresh basil, torn
- 1 tablespoon fresh oregano, chopped
- Lemon wedges for serving
Instructions
- Whisk together the olive oil, garlic, salt, and pepper. Brush generously over all the vegetables and halloumi slices.
- Preheat the grill to medium-high heat, about 425°F. Clean and oil the grates well.
- Grill the vegetables in order of cook time: onion rounds and portobello caps go on first, about 5 to 6 minutes per side. Peppers, zucchini, and squash next, about 3 to 4 minutes per side. Asparagus last, about 2 to 3 minutes, rolling them frequently.
- Grill the halloumi slabs 2 to 3 minutes per side until golden grill marks appear and the edges are softened.
- Arrange everything on a large platter. Drizzle with balsamic vinegar, scatter the basil and oregano over the top, and serve with lemon wedges.
Notes
- Halloumi has a very high melting point, which is why it holds its shape on the grill — but it must be eaten hot, because it turns rubbery as it cools.
- Cut vegetables into similar thicknesses so they cook evenly. Thin slices char too quickly, thick pieces stay raw inside.
- Use a grill basket for smaller vegetables like asparagus to prevent them from falling through the grates.

Frequently Asked Questions
What can I substitute if I’m missing an ingredient?
No portobellos on hand? Cremini or a second zucchini fill in fine. Halloumi is the one non-negotiable ingredient; feta and mozzarella melt through the grates instead of holding their shape.
How long does this keep in the refrigerator?
The vegetables hold for two to three days refrigerated, but grill the halloumi fresh each time. It turns rubbery once it has been chilled and reheated.
Is this recipe kid-friendly?
Yes. The vegetables are mild and the halloumi is just salty, squeaky cheese, nothing spicy. Cut it into smaller pieces for younger kids, since the slabs come off the grill fairly large.
