Ingredients Notes
For the best flavor, choose fresh and firm zucchinis. Look for zucchinis about six to eight inches long, as they tend to be sweeter and less watery. If you’re out of olive oil, you can easily substitute it with avocado oil for a rich, buttery taste. Add a sprinkle of red pepper flakes if you love a spicy kick.
Recipe Steps
Step 1
Preheat your grill to a medium-high temperature, around 400°F (200°C). Clean the grill grates thoroughly to prevent sticking.
Step 2
Slice zucchinis lengthwise into 1/4-inch thick strips. This uniform size ensures even cooking and perfect char lines.
Step 3
Toss zucchini slices in a bowl with olive oil, salt, and pepper. Make sure each piece is well-coated to enhance flavor during grilling.

Storage Options
Store any leftovers in an airtight container in the refrigerator for up to three days. To reheat, place zucchini slices on a baking sheet and warm in the oven at 350°F (175°C) for 5-10 minutes. Avoid microwaving as it can make the zucchini mushy. For freezing, slice before storing, and use within two months to maintain quality.
Variations & Substitutions
For a vegan twist, drizzle with balsamic glaze before serving. You can spice up the dish with cajun seasoning or incorporate garlic powder for extra flavor. Uses such as zucchini chips or dip into a yogurt-based sauce can change the side dish into a delightful snack.
Frequently Asked Questions
Can I use other types of squash in this recipe? Absolutely! While zucchini is traditional, summer squash or even eggplant can be grilled in the same manner. Just adjust cooking times slightly, as different vegetables may vary in water content.
Is there an oven option if I don’t have a grill? Yes, you can roast the zucchini in the oven. Preheat your oven to broil, lay zucchini on a baking sheet, and cook for around 5-7 minutes on each side, watching closely to prevent burning.
What’s the best way to cut even zucchini slices? For even slices, use a mandoline or a sharp chef’s knife. Consistent thickness ensures uniform grilling and improves presentation on the plate.
