Quick, vibrant side: slice zucchinis and thread with bell pepper and red onion onto skewers. Melt butter with garlic, parsley and lemon zest, then brush before grilling over medium-high heat 3-5 minutes per side until tender and slightly charred. Finish with remaining garlic butter and lemon wedges. Serves 4; soak wooden skewers first and swap vegetables as desired.
My neighbor Tom tossed a bag of zucchini over the fence last July and yelled try grilling these before I could even say thanks.
I brought a platter of these to a backyard potluck and three people asked for the recipe before I even sat down with my own plate.
Ingredients
- Zucchini (3 medium): Slice them uniformly so everything cooks evenly, and pick ones that feel firm with no soft spots.
- Red bell pepper (1): Optional, but the sweet pops of color make the skewers look as good as they taste.
- Red onion (1 small): Cut into chunks that are big enough to hold together on the grill without falling through the grates.
- Unsalted butter (4 tbsp): Unsalted lets you control the seasoning, and the butter carries the garlic flavor into every bite.
- Garlic cloves (3, minced): Fresh is nonnegotiable here because the jarred stuff loses the punch that makes this dish sing.
- Fresh parsley (2 tbsp, chopped): Adds a bright herbal finish that balances the richness of the butter.
- Salt (1/2 tsp): Draws out moisture and seasons the vegetables from the outside in.
- Black pepper (1/4 tsp): A gentle warmth that does not compete with the garlic.
- Lemon zest (1/2 tsp): This tiny addition wakes up the whole flavor profile and makes people wonder what your secret is.
- Skewers (8 wooden or metal): Soak wooden ones ahead of time unless you enjoy the smell of burning wood more than cooking food.
- Lemon wedges (for serving): A squeeze at the end ties everything together beautifully.
Instructions
- Soak the skewers:
- Drop your wooden skewers into a pan of water and let them soak for at least 20 minutes so they do not ignite on the grill.
- Heat the grill:
- Get your grill screaming hot at medium high, around 400 degrees, because you want those beautiful char marks.
- Make the garlic butter:
- Melt the butter gently in a small saucepan, add the minced garlic, and let it sizzle for just a minute until your whole kitchen smells incredible.
- Thread the vegetables:
- Alternate zucchini, pepper, and onion onto each skewer, packing them snugly so nothing flops around when you flip.
- Brush with butter:
- Coat the skewers generously with half your garlic butter, saving the rest for a finishing flourish.
- Grill to perfection:
- Lay them on the grates and cook 3 to 5 minutes per side, turning until you see tender centers and gorgeous dark char spots.
- Finish and serve:
- Pull them off the heat, brush on every last drop of remaining garlic butter, and arrange on a platter with lemon wedges beside them.
Standing by the grill with tongs in one hand and a cold drink nearby, watching those skewers pick up color, is the kind of evening that makes summer worthwhile.
A Note on Vegetables That Play Nice
Cherry tomatoes and cremini mushrooms are welcome additions, but keep in mind tomatoes cook faster and may burst if left too long.
What to Serve Alongside
These skewers love the company of grilled chicken thighs or a big scoop of herbed couscous on the side.
Making It Your Own
A pinch of red pepper flakes over the top right before serving transforms the whole plate into something with a sneaky little kick.
- Try swapping parsley for fresh basil if you have some going wild in the garden.
- A light sprinkle of parmesan at the end never hurt anybody.
- Taste before you serve because every grill and every batch of garlic is different.
These skewers are proof that a handful of simple ingredients and a hot grill can create something truly memorable.
Questions & Answers
- → How long should I grill the zucchini?
-
Grill skewered zucchini over medium-high heat for about 3-5 minutes per side, until tender and marked with char spots. Thicker slices may need an extra minute or two.
- → How do I prevent wooden skewers from burning?
-
Soak wooden skewers in water for at least 20 minutes before grilling. Alternatively use metal skewers or place skewers perpendicular to grill grates to reduce direct flame contact.
- → Can I swap in other vegetables?
-
Yes. Cherry tomatoes, mushrooms, summer squash, or eggplant work well. Thread firmer vegetables first and keep similarly sized pieces for even cooking.
- → What's the best way to prepare the garlic butter?
-
Melt butter gently over low heat, add minced garlic and cook briefly until fragrant (about 30-60 seconds) to avoid bitterness. Stir in parsley, lemon zest, salt and pepper, then brush on skewers before and after grilling.
- → How can I stop zucchini from sticking to the grill?
-
Preheat the grill until hot, oil the grates lightly or brush vegetables with garlic butter before grilling, and avoid moving skewers too soon—allow a good sear before turning.
- → Are there simple swaps for dietary restrictions?
-
For dairy-free needs, use a plant-based butter or olive oil infused with garlic and herbs. The vegetables are naturally gluten-free and vegetarian when using appropriate butter alternatives.
