Ingredients Method Notes

Ingredients
  

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

Method
 

Season the vegetables
  1. Toss the zucchini and yellow squash with olive oil, minced garlic, Italian seasoning, salt, and black pepper until evenly coated.
Grill
  1. Preheat the grill to medium-high (about 400–450°F) and clean and oil the grates to prevent sticking.
  2. Place vegetables on the grill and cook 3–4 minutes per side without moving until grill marks form and the squash is tender.
Serve
  1. Arrange the grilled vegetables on a platter alternating zucchini and yellow squash so the colors show clearly.
  2. Drizzle with lemon juice and the remaining garlic oil for bright flavor right before serving.
  3. Scatter chopped fresh parsley over the top and grate parmesan over if desired.

Notes

Pro tip: keep the planks in a single layer and avoid moving them during grilling so the grill marks stay crisp and defined. Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat briefly on a hot grill pan or skillet, or serve at room temperature. Freezing is not recommended as the squash texture softens. For a dairy-free swap, skip parmesan and increase parsley slightly or add extra lemon juice to keep flavor bright.
