Prep Time 25 minutes
Cook Time 8 minutes
Servings 6 -8 servings


  • 6 small to medium zucchini, ends trimmed off, cut into 1/3-inch wide planks
  • 1/4 cup extra virgin olive oil
  • 3 tablespoons lemon juice (1 lemon)
  • zest of 1 lemon
  • 3 cloves garlic, minced
  • 1 tsp EACH dried parsley, dried basil
  • 1 teaspoon kosher salt (or ½ tsp table salt)
  • 1/2 teaspoon pepper


  • Whisk all of the ingredients together except the zucchini in a freezer size sealable bag. Add the zucchini and turn to coat. Marinate for 20 minutes at room temperature or up to 2 hours in the refrigerator if making ahead.
  • Preheat a grill to 400-425 degrees F or an indoor grill pan to medium-high heat. Clean and grease the grill/pan.
  • Let the marinate drip off of the zucchini (don't rub off) and add the zucchini to the grill in a single layer. Cook for 3-4 minutes per side or just until crisp-tender (don’t overcook!). Transfer to a serving platter and brush with some leftover marinade if desired. Best if served immediately (will soften as it cools).

How to store zucchini

  • To Store: refrigerate grilled zucchini in an airtight storage container for up to 3 days in a single layer or with parchment in between the layers.
  • To Reheat: line the zucchini in a single layer on a baking sheet and bake at 350 degrees F until warmed through, 5-10 minutes or rewarm at 20 second intervals in the microwave.
  • Can I freeze zucchini?  I do not recommend freezing grilled zucchini because it is 94% water and will become mushy once thawed.
