Ingredients
  

Vegetables and seasonings
  • 2 zucchini sliced diagonally into 1/3-inch planks
  • 2 yellow squash sliced diagonally into 1/3-inch planks
  • 3 tbsp olive oil
  • 3 clove garlic minced
  • 1 tsp Italian seasoning
  • 0.25 tsp salt to taste
  • 0.25 tsp black pepper to taste
  • 2 tbsp fresh parsley chopped
  • 1 tbsp lemon juice
  • 1 Parmesan optional for finishing

Equipment

  • 1 sheet pan

Method
 

Season the vegetables
  1. Toss zucchini and yellow squash with olive oil, minced garlic, Italian seasoning, salt, and black pepper until evenly coated and lightly glossy.
  2. Let the seasoned vegetables sit briefly on a sheet pan while the grill heats, about 2–3 minutes.
Grill
  1. Preheat the grill to medium-high and clean and oil the grates so the planks won’t stick.
  2. Lay vegetables on the grill in a single layer and grill 3–4 minutes per side without moving, until grill marks form and the squash is tender.
Finish and serve
  1. Arrange the grilled vegetables on a platter alternating zucchini and yellow squash for a striped look.
  2. Drizzle with lemon juice and any remaining garlic oil over the top.
  3. Scatter chopped fresh parsley over the top, then grate Parmesan over if desired.

Notes

For best grill marks, keep planks around 1/3-inch thick so they cook at the same pace; thicker pieces may need a few extra minutes per side. Refrigerate leftovers in an airtight container up to 3 days and reheat quickly on a hot grill or in a skillet until warmed through. Freezing is not recommended because the squash texture softens. For a dairy-free option, skip Parmesan and add extra black pepper or a pinch of smoked paprika for similar punch.
