Save to Pinterest Tender zucchini rounds grilled to perfection and basted with a rich garlic butter mixture, creating a simple yet irresistible side dish or appetizer that bursts with flavor. These skewers come together in just 25 minutes, with only 15 minutes of prep time needed. The zucchini is cut into thick rounds, threaded onto skewers, and brushed generously with a homemade garlic butter blend featuring minced garlic, fresh parsley, and lemon juice.
Grilled over medium-high heat for 4-5 minutes per side, the zucchini becomes tender while developing beautiful light grill marks. Brushing with additional garlic butter during grilling infuses even more savory flavor throughout. The dish is naturally vegetarian and gluten-free, easily adaptable for vegan diners with plant-based butter substitutions.
Serve alongside grilled meats for a complete meal, or enjoy as a vegetarian main with rice or quinoa. Optional Parmesan cheese and extra fresh parsley make perfect finishing touches. These skewers work wonderfully for summer cookouts, weeknight dinners, or whenever you crave fresh vegetables with elevated, buttery flavor.
The smell of garlic hitting hot butter on a summer evening still takes me back to my neighbors backyard cookout where I first watched someone brush this mixture over sizzling zucchini.
I burned the first batch because I walked away to check on drinks and learned that zucchini needs your full attention for those perfect grill marks.
Ingredients
- Zucchini: Pick firm ones with tight skin because soft or bruised zucchini turns mushy on the grill.
- Unsalted butter: Lets you control the salt level while giving the garlic something rich to bloom in.
- Fresh garlic: Mince it fine so it melts into the butter without leaving harsh raw bits.
- Fresh parsley: Adds a bright finish that cuts through the richness of the butter.
- Lemon juice: A small splash wakes up all the flavors and balances the fat.
- Salt and pepper: Season generously since zucchini is naturally mild.
- Parmesan cheese: Optional but adds a savory punch at the end.
Instructions
- Fire up the grill:
- Get your grill or grill pan to medium high heat so you get nice char without burning the exterior before the inside tenderizes.
- Whisk the garlic butter:
- Stir melted butter with minced garlic, parsley, lemon juice, salt, and pepper in a small bowl until everything is well combined.
- Thread the zucchini:
- Slide zucchini rounds onto skewers leaving small gaps between pieces so the heat can circulate and cook evenly.
- Brush with butter:
- Coat each skewer generously on all sides making sure every piece gets its share of the garlic mixture.
- Grill to perfection:
- Cook four to five minutes per side turning once until tender with light grill marks and brush again midway for extra flavor.
- Finish and serve:
- Pull the skewers off the heat and shower with Parmesan and extra parsley if you want to dress them up.
Save to Pinterest These skewers disappeared so fast at my last potluck that I started making a double batch just so I could actually taste one.
What to Serve Alongside
This pairs beautifully with grilled chicken, steak, or even a simple bowl of rice for a light vegetarian meal.
Making It Your Own
Cherry tomatoes or chunks of bell pepper threaded between the zucchini add pops of color and sweetness that complement the savory butter.
Storage and Leftovers
Keep any extra skewers in the fridge for up to three days and reheat gently in a pan.
- A quick warm up in a skillet brings back the fresh grilled texture better than the microwave.
- Leftovers chop up beautifully into pasta or grain bowls the next day.
- Let them come to room temperature before reheating for the best results.

Recipe Help & Support
- → How do I prevent zucchini from falling through the grill grates?
-
Thread zucchini rounds onto skewers, leaving space between pieces for even cooking. This keeps them secure while allowing heat to circulate properly. Metal skewers work best, but soaked wooden skewers also work well.
- → Can I make these skewers in the oven instead?
-
Yes! Preheat your oven to 425°F and place skewers on a baking sheet. Roast for 12-15 minutes, turning halfway through, until tender and lightly browned. Brush with garlic butter before and during cooking.
- → How long should I cook zucchini on the grill?
-
Cook for 4-5 minutes per side over medium-high heat, turning once. Total grilling time should be 8-10 minutes. You'll know they're done when the zucchini feels tender and shows light grill marks.
- → What other vegetables can I add to these skewers?
-
Cherry tomatoes, bell pepper chunks, red onion slices, or yellow squash all pair beautifully. Just make sure to cut vegetables into similar sizes so they cook evenly on the grill.
- → Can I prepare the garlic butter mixture ahead of time?
-
Absolutely! Mix the garlic butter up to 2 days in advance and store it in an airtight container in the refrigerator. Bring it to room temperature before brushing onto the zucchini for easier application.
- → How do I make this dish dairy-free?
-
Substitute the unsalted butter with your favorite plant-based butter alternative. Omit the optional Parmesan cheese garnish or use a dairy-free Parmesan substitute. The rest of the ingredients are naturally dairy-free.
