Savor the vibrant flavors of summer with this easy grilled zucchini recipe that truly brings out the best of garden-fresh produce. When Memorial Day arrives and the grill takes center stage, this side becomes a favorite on my table for its simplicity and unbeatable taste.
I first made this for a backyard gathering where I wanted something light on the grill. Now my friends ask for it every chance they get because the smoky flavor and tender texture win everyone over.
Ingredients
- Medium zucchinis: sliced into quarter inch rounds look for firm and glossy skin for the best flavor and texture
- Olive oil: coats each slice and helps get that perfect grilled char choose extra virgin if possible for richer taste
- Garlic powder: adds a gentle punch of savory flavor opt for a fresh new jar for boldness
- Salt: essential for pulling out the zucchini’s natural sweetness use flaky or kosher for more flavor
- Black pepper: gives a warm undertone freshly cracked has the biggest impact
- Fresh herbs such as basil or parsley: brighten every bite select vibrant leaves for maximum aroma
Step-by-Step Instructions
- Prep the Grill:
- Turn your grill on to medium high heat and take a couple minutes to scrub the grates clean with a stiff brush. This step prevents sticking and helps get those beautiful grill marks.
- Season the Zucchini:
- Put your zucchini rounds in a large mixing bowl and drizzle with the olive oil. Sprinkle over garlic powder salt and black pepper. Toss everything together using your hands or tongs so every slice is evenly coated and glistening.
- Arrange on the Grill:
- Lay the zucchini slices directly on the grates in a single layer. Space them out so each one has contact with the grill and can caramelize.
- Grill to Perfection:
- Let the zucchini cook undisturbed for three to four minutes. When you see solid grill marks on the underside use tongs to flip each piece and cook another three minutes until tender but not mushy.
- Add Fresh Herbs:
- Scatter your chosen herbs over the zucchini during the last minute on the grill. The heat will bring out their essential oils and make the flavors pop.
- Serve and Enjoy:
- Carefully lift each slice off the grill and arrange on a platter. Serve immediately while still hot with an extra sprinkle of herbs or a drizzle of lemon juice if desired.

Fresh basil is always my favorite garnish because its sweet anise notes pair beautifully with the charred vegetables. One of my favorite summer memories is watching my daughter pick fresh basil leaves and scatter them over the platter before we all dove in.
Storage tips
Let leftover grilled zucchini cool completely before storing. Transfer to an airtight container and keep in the refrigerator for up to three days. Eat cold tossed in salads or rewarm gently in a skillet to preserve texture. I do not recommend freezing as zucchini can get watery.
Ingredient substitutions
No olive oil on hand Try avocado oil. You can also sprinkle the zucchini with smoked paprika for a twist or use Italian seasoning in place of garlic powder. For a dairy boost top the finished slices with crumbled feta or grated parmesan which both add creamy salty notes.
Serving suggestions
Pair grilled zucchini with other grilled vegetables for a rainbow platter. Tuck it into grain bowls layer in sandwiches or use as a topping for flatbreads. It is also lovely alongside grilled chicken salmon or burgers for a light and balanced meal.

Cultural context
Grilling zucchini has roots in Mediterranean cooking where fresh vegetables meet open fire for smoky depth. It is always popular during summertime celebrations in the United States like Memorial Day because it is simple fast and brings out the natural sweetness of the squash.
