Step by step
Tap a step to cross it offCut Veg to Uniform Size
8 minSlice 2 medium zucchini into 1-inch coins. Cut 2 bell peppers (mixed colors) into 1-inch squares. Cut 1 red onion into 1-inch wedges, keeping some root attached so wedges hold together. Rinse 1 pint cherry tomatoes.
WhyUniform 1-inch pieces cook at the same rate. Small pieces burn while big ones stay raw — this is the number one skewer failure mode.
Whisk the Marinade
In a large bowl, whisk together 1/4 cup extra-virgin olive oil, 2 tbsp balsamic vinegar, 1 tbsp Dijon mustard, 3 minced garlic cloves, 1 tsp kosher salt, 1 tsp dried oregano, and 1/2 tsp black pepper.
WhyDijon is the emulsifier — it keeps the oil and vinegar mixed so every piece of vegetable gets coated instead of the marinade separating in the bowl.
Marinate 20 Minutes
20 minAdd all cut vegetables to the bowl and toss to coat every piece. Let sit at room temp for 20 minutes, tossing once at the halfway point. Reserve 3 tbsp marinade for drizzling later.
Why20 minutes is the sweet spot. Longer and the salt draws too much water out of the zucchini — you end up with soggy skewers instead of char.
Thread Skewers Alternating
Thread vegetables onto 8 skewers, alternating colors and shapes — pepper, zucchini, onion, tomato, repeat. Leave 1/4 inch of space between each piece for heat circulation.
WhyCrowded skewers steam their neighbors and never char. Space matters — this is why the pretty picture skewers actually taste better than the packed ones.
Grill Direct Heat 12 Minutes
12 min · flip at 6Preheat grill to 400°F. Place skewers directly over the heat. Grill 6 minutes per side, rotating once, until vegetables have deep grill marks and are just-tender but still hold their shape.
WhyOver-cooked grilled veg is a puddle. Pull when zucchini has a slight give but still has texture — the skewers keep cooking for another 90 seconds after you plate them.
Drizzle and Serve
Transfer skewers to a platter. Drizzle with the reserved 3 tbsp marinade. Finish with a pinch of flaky sea salt and 2 tbsp torn fresh basil.
WhyReserved-marinade drizzle is what lifts these from side dish to something people compliment. Skip it and they're just plain grilled vegetables.

Frequently Asked Questions
Can I add mushrooms or halloumi?
Yes — mushrooms grill in the same time; halloumi in half the time. Cube halloumi 1-inch and put on its own skewer so it doesn't overcook waiting on the veg.
Can I do these in the oven?
Yes, spread on a sheet pan and broil 8 minutes total, flipping once. Not the same char, but same idea.
How do you reheat leftover grilled vegetable skewers without ruining the texture?
