These grilled zucchini skewers transform simple summer squash into something spectacular. Medium rounds are threaded onto skewers and grilled until tender with gorgeous char marks, then brushed generously with a fragrant butter mixture infused with fresh garlic, parsley, and lemon zest. The result is beautifully caramelized vegetables with a rich, savory coating that complements their natural sweetness.
Ready in just 25 minutes, these skewers work wonderfully as a light vegetarian main or as a versatile side alongside grilled chicken, fish, or steak. The garlic butter adds luxurious flavor while keeping things incredibly simple. Finish with optional Parmesan and serve with extra lemon wedges for bright acidity that cuts through the butter.
Last summer, my neighbor kept dropping off zucchinis from her garden like she was trying to get rid of evidence. I threw these skewers together on a Tuesday evening when cooking felt like a chore, and somehow they became the thing my actual friends started requesting at potlucks. The smell of garlic butter hitting hot zucchini makes people wander over to the grill like it's a magnetic force.
I made these for my dad who claims to hate vegetables, and he ate six skewers before realizing they were, in fact, vegetables. My sister-in-law asked for the recipe while she was still chewing her first bite. Now they show up at every family gathering, and I've stopped pretending they're complicated.
Ingredients
- 3 medium zucchinis: Slice them into half-inch rounds so they stay chunky and don't turn to mush on the grill
- 3 tablespoons unsalted butter: Melt it before mixing so it coats everything evenly without clumping
- 3 cloves garlic: Finely mince it fresh because jarred garlic never quite hits the same aromatic notes
- 2 tablespoons fresh parsley: Chop it right before you need it so it stays bright and doesn't wilt
- 1 teaspoon lemon zest: Use a microplane if you have one to avoid the bitter white pith
- ½ teaspoon salt and ¼ teaspoon black pepper: This is your base seasoning, but trust your own taste buds here
- 2 tablespoons grated Parmesan cheese: Optional but honestly recommended because salty cheese is never a bad decision
- Lemon wedges: Keep them whole for squeezing at the end, not cooking
Instructions
- Fire up the grill:
- Get your grill or grill pan humming at medium-high heat, letting it preheat while you prep everything else
- Mix the magic butter:
- Whisk together the melted butter, garlic, parsley, lemon zest, salt, and pepper until it's all friends
- Thread those zucchinis:
- Slide the zucchini rounds onto skewers with enough space between each piece for heat to circulate and do its job
- First coat:
- Brush the zucchini generously with half the garlic butter mixture before they hit the grates
- Get the char:
- Grill for 3 to 4 minutes per side, turning once, until the zucchini is tender and sporting those gorgeous grill marks
- Final butter bath:
- Remove from the grill and immediately brush with the remaining garlic butter while everything's still sizzling hot
- The finishing touches:
- Sprinkle with Parmesan if you're using it and serve with lemon wedges for that bright acidic kick
These skewers have become my go-to when I want something that feels special but doesn't require measuring or stress. The way the butter pools in the zucchini curves and the cheese melts into those little crevices, it's just simple food done really well.
Grill Temperature Secrets
Medium-high is around 375 to 400 degrees, perfect for getting grill marks without incinerating the butter. You know you're at the right temperature when you can hold your hand above the grates for about 4 seconds before pulling away. Too hot and the garlic burns, too cool and you get soggy zucchini.
Zucchini Selection
Medium zucchinis are the sweet spot for this recipe. Too small and they dry out, too large and they get watery and sad. Look for firm skin without soft spots and check that the ends aren't shriveled. Farmer's market zucchinis tend to have better flavor than supermarket ones that have been sitting around.
Make It Your Own
These skewers are incredibly forgiving, which is partly why they work so well for weeknight dinners or feeding a crowd. The basic formula is solid, but there's room to play based on what you have or what sounds good.
- Add chili flakes to the butter if you like everything with a little kick
- Swap parsley for basil or dill depending on what's growing in your garden or what's on sale
- These pair beautifully with grilled chicken, fish, or can stand alone as a vegetarian main with some crusty bread
Serve these while they're still warm with that butter dripping down your chin. They're the kind of simple summer food that makes people ask, 'When are you making these again?'
Recipe FAQs
- → Can I make these zucchini skewers in the oven?
-
Yes, absolutely. Preheat your oven to 425°F and place the prepared skewers on a baking sheet lined with parchment paper. Broil for 3-4 minutes per side until tender and lightly charred, watching closely to prevent burning.
- → Do I need to soak wooden skewers before grilling?
-
If using wooden skewers, soak them in water for at least 30 minutes before threading the zucchini. This prevents them from burning on the grill. Metal skewers can be used directly without soaking.
- → How do I prevent the zucchini from falling apart on the grill?
-
Use firm, fresh zucchinis and cut them into uniform ½-inch thick rounds. Thread them carefully onto skewers, leaving small gaps between pieces for even heat distribution. Avoid overcooking, which can make the zucchini too soft.
- → Can I prepare the garlic butter mixture ahead of time?
-
The garlic butter mixture can be prepared up to 24 hours in advance and stored in the refrigerator. Let it come to room temperature before using, or gently warm it slightly so it spreads easily on the zucchini.
- → What other vegetables work well on these skewers?
-
Yellow squash, bell peppers, red onion, cherry tomatoes, and eggplant all pair beautifully with the garlic butter. Just keep in mind that different vegetables may require varying cooking times.
- → How should I store leftovers?
-
Store leftover skewers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 350°F oven for 5-7 minutes or enjoy them cold in salads.
