Thoroughly clean the grill grates and lightly oil them to prevent sticking. Preheat the grill on medium-high to around 375-400°F (190-205℃). If using charcoal, make sure the coals are evenly lit and glowing.
Rinse the squash in cold water, and pat them dry with paper towels. Cut off the ends, then slice them lengthwise into quarters (or other desired shape). Cut them into similar sizes for even cooking.
Place the wedges on a large plate or baking tray.
Whisk the olive oil, salt, black pepper, garlic, basil, oregano, thyme, and lemon juice in a small bowl.
Brush both sides of the wedges with the seasonings until thoroughly coated. Grill them for 3-4 minutes per side, keeping a close eye on them to prevent overcooking.
Remove from the grill, sprinkle with freshly grated Parmesan, and serve immediately.
Notes
Summer squash cooks fast, so preheat the grill for hot grates that will create those beautiful grill marks.
Slice the squash evenly to ensure consistent cooking.
A grill basket or skewers will prevent the slices from falling through the grates.
