These Mediterranean-inspired skewers feature fresh zucchini slices grilled until tender with gorgeous char marks. The crowning glory is a generous brushing of aromatic garlic butter infused with parsley and bright lemon zest. Ready in just 25 minutes, these make an effortless side for grilled meats or a satisfying vegetarian main course.
My neighbor Sarah brought these to our 4th of July block party last summer, setting up a little portable grill right on her driveway. Everyone abandoned the burgers to hover around her skewers instead. The smell of garlic butter hitting hot zucchini drew people in from three houses down. I've been making them weekly ever since.
Last Tuesday I made a double batch for my sister who swears she hates zucchini. She ate five skewers standing at the counter, barely coming up for air. Sometimes the simplest vegetables just need the right treatment to shine.
Ingredients
- 3 medium zucchinis: Look for firm ones with smooth skin and slice them exactly 1/2 inch thick so they cook evenly without falling apart
- 3 tablespoons unsalted butter: Melt it completely so it coats every surface, and dont skimp here because this is what carries all the flavor
- 3 cloves garlic: Mince it finely so you get garlic in every bite without any harsh raw chunks
- 2 tablespoons fresh parsley: Chop it right before using so it stays bright and adds that fresh pop against the rich butter
- 1 teaspoon lemon zest: Use a microplane if you have one to get just the yellow part without any bitter pith
- 1/2 teaspoon salt and 1/4 teaspoon black pepper: Season generously because zucchini needs a little help to really sing
- 2 tablespoons grated Parmesan cheese: Sprinkle this on at the very end so it melts slightly into the warm butter
Instructions
- Heat things up:
- Get your grill or grill pan going at medium high heat until its nicely hot and ready to sear
- Make the magic butter:
- Whisk together the melted butter, minced garlic, parsley, lemon zest, salt, and pepper until everything is well combined
- Thread carefully:
- Slide the zucchini rounds onto your skewers with tiny spaces between pieces so the heat can circulate and cook them through
- First brush:
- Paint half that garlic butter mixture all over the zucchini, getting into every crevice and coating both sides well
- Grill time:
- Cook for 3 to 4 minutes per side, turning once, until the zucchini is tender when pierced and has beautiful charred lines
- Final flourish:
- Brush the skewers immediately with the remaining garlic butter while they are still hot, then sprinkle with Parmesan if you like
These have become my go to for impromptu backyard gatherings because they come together so fast. Theres something wonderful about food cooked on sticks that makes people relax and linger longer at the table.
Getting The Perfect Grill Marks
Resist the urge to move the skewers around too much while they cook. Let them sear undisturbed for those first few minutes so the grill marks can develop properly. The zucchini will release naturally when its ready to be turned.
Temperature Control Matters
Too high and the outside will burn before the inside gets tender. Too low and you will miss those gorgeous charred flavor spots. Medium high is that sweet spot where the zucchini cooks through while still developing that grilled taste we all love.
Make Ahead Friendly
You can slice the zucchini and mix the garlic butter up to a day ahead, keeping everything separately covered in the refrigerator. The butter will firm up but just give it a quick zap in the microwave before brushing.
- Let the zucchini come to room temperature for 20 minutes before grilling so it cooks evenly
- Have all your tools ready before you head to the grill because this cooks fast
- Keep a little extra lemon handy for a final squeeze right before serving
Summer eating should be this simple and satisfying always. Hope these skewers find their way to your next grill session and become a regular in your rotation too.
Recipe FAQs
- → How do I prevent zucchini from falling through the grill grates?
-
Using skewers keeps the zucchini rounds secure while grilling. Metal skewers work best, but if using wooden ones, soak them in water for 30 minutes beforehand to prevent burning.
- → Can I make these in the oven instead?
-
Absolutely. Preheat your oven to 425°F and place the skewers on a baking sheet. Roast for 15-20 minutes, turning halfway through, until tender and lightly browned.
- → What other vegetables work well with this garlic butter?
-
This versatile garlic butter pairs beautifully with grilled summer squash, bell peppers, mushrooms, eggplant, or even corn on the cob. Feel free to create mixed vegetable skewers using the same technique.
- → How long will these keep in the refrigerator?
-
Store leftover skewers in an airtight container for up to 3 days. Reheat gently on the grill or in a 350°F oven until warmed through. Note that the texture will soften after refrigeration.
- → Can I prepare the garlic butter ahead of time?
-
Yes, mix the garlic butter up to 2 days in advance and store it refrigerated. Bring it to room temperature before using so it spreads easily over the zucchini.
