Ingredients
For 4 servings (about 8–10 skewers)
Vegetable Skewers
- 4 medium red onions (cut into 6 wedges each)
- 4 medium zucchinis (sliced into ½-inch rounds)
- 2 each of red, orange, yellow, and green bell peppers (seeded, chopped into 1″ pieces)
- Olive oil, for brushing
- Balsamic vinegar, for serving (optional)
Garlic-Herb Sauce
- ⅓ cup olive oil
- 5 garlic cloves, minced

- 1 tsp fresh rosemary, minced
- Salt + freshly ground black pepper, to taste
Other
- 8–12 wooden or metal skewers

Key Ingredients
Let’s unpack the magic players that make these veggie skewers pop.
Zucchini
Golden when grilled, zucchini offers tender softness and grill-friendly texture. It absorbs flavors beautifully while holding its shape—making it skewer gold.
Bell Peppers
A rainbow of colors—red, orange, yellow, green—adds sweetness, crunch, and visual drama. Their thick flesh delivers satisfying texture and char without collapsing.
Red Onion
Caramelized and lightly charred, red onion becomes smoky and sweet, adding depth to every bite. It also helps anchor veggies to the skewer.
Garlic-Herb Sauce
A zesty brush-on blend of garlic, fresh herbs, and olive oil. It transforms simply-grilled veggies into herbaceous, savory bites dripping with flavor.
Optional Balsamic Vinegar
A punch of tang and a dash of sweetness—drizzle this at the end for acidity that cuts through the richness.
Steps: How to Make Grilled Veggie Skewers

Cook Time

Servings

1. Prep Skewers & Veggies
If using wooden skewers, soak them in water for 15–30 minutes to prevent burning. Meanwhile, prepare the vegetables:
- Red onions: Peel, halve, then cut each half into 3 wedges (6 pieces per whole onion).
- Bell peppers: Remove stem and seeds, chop into ~1″ squares.
- Zucchini: Trim ends, slice into ½″ rounds.
Evenly sized pieces = even cooking, so take your time.
2. Make the Garlic-Herb Sauce
In a medium bowl, whisk ⅓ cup olive oil, minced garlic, parsley, cilantro, rosemary, salt, and pepper. Set aside to allow flavors to mingle.
3. Thread the Skewers
Alternate veggies on each skewer: start with a red onion wedge, then zucchini, then pepper, and repeat until filled — leaving ~½ inch free at each end. Make sure pieces aren’t packed too tightly so heat can circulate.
4. Preheat Your Grill
Heat your grill to medium-high (375–400°F). Oil grates lightly to prevent sticking.
5. Grill the Skewers
Brush skewers lightly with olive oil, then place them on the grill. Cook for 5–8 minutes per side (total 10–16 minutes), turning gently to achieve even char. Veggies are done when tender but still hold shape, with brown edges.
6. Finish & Serve
Remove skewers from heat. Brush each with garlic-herb sauce while still warm. If using, drizzle lightly with balsamic vinegar. Serve hot or at room temperature for maximum flavor.

Tips for Best Results
Even Sizing
Try to make vegetable pieces roughly the same volume—this helps them cook evenly. Round veggies like zucchini may need slightly thicker cuts than bell peppers.
Soak Wooden Skewers
Prevent flare-ups by soaking wooden skewers in water for 15–30 minutes before threading veggies.
Rotate Carefully
Use tongs to gently rotate; avoid piercing veggies, which may cause juices to escape.
Embrace Light Charring
A bit of color adds flavor—so don’t shy away from those golden edges. Just watch closely to avoid burning.
Herb Substitutions
Swap parsley and cilantro for mint, basil, or oregano if you prefer. Keep the sauce fresh and fragrant.
Make-Ahead Prep
Chop vegetables and prep sauce the night before. Store separately in airtight containers and assemble just before grilling.
