How to Make Excellent Grilled Zucchini and Summer Squash

Gather the ingredients. The Spruce Featured Video Heat a charcoal or gas grill to medium-high heat (you should be able to hold your hand about an inch above the cooking grate for 3 to 4 seconds before pulling it away from the heat). The Spruce While the grill heats, trim the zucchini and cut it in half lengthwise (or into lengthwise slices for thicker vegetables). Lay it on a large baking sheet or tray. Brush the cut sides with olive oil and sprinkle them with salt. Lay the zucchini oiled-side-down on the grill. Close the lid if using a gas grill and cook until grill marks appear. This will take an average of about 5 minutes. The Spruce While the zucchini/squash cooks, brush the other sides with oil and sprinkle them with salt. Turn the zucchini/squash halves over, close the lid on a gas grill and cook until grill marks appear on the other side and the zucchini/squash are very tender, which will take about 5 minutes. Serve hot or at room temperature. The Spruce Enjoy!
