1. Soak the Skewers

First things first, if you’re using wood skewers, soak them in water. We don’t want them catching fire on the grill! Unless, of course, you enjoy your kebabs with a side of fire department visit. 

2. Prep the Vegetables

Chop off the vegetable stems. Cut zucchini and yellow squash into ½” disks to make perfect bite-sized pieces. Slice the peppers and onions into 2-3” chunks, and don’t forget to separate those onion layers. 

3. Mix the Marinade

In a large bowl, whisk together all the Italian marinade ingredients. 

4. Marinate the Veggies

Add the kebab vegetables to the marinade. Toss and coat them all over with seasonings. Marinate for 30 minutes on the counter if you have the time, for more flavor.

5. Skewer the Vegetables

Thread the veggies onto the skewers, mixing up the order so it looks like a veggie rainbow. Leave 2” open on either side of the skewers to handle them. You don’t want to lose any precious kebabs while they grill!

6. Prepare the Grill

Brush the grill with oil if you like, though the marinade usually does a good job of preventing sticking. Set one burner on the gas grill to medium heat. The others stay off for now.

7. Grill the Kebabs (Indirect Heat)

Place the skewers on the grill grates in the indirect heat area. This is where there’s no flame directly beneath them. Close the grill cover and let them cook for 6 minutes, away from the direct flame. Think of it as a warm-up session for the veggies.

8. Grill the Kebabs (Direct Heat)

Open the grill and move the skewers directly over the medium-heat flame. Leave the cover off and rotate the skewers every 1-2 minutes. Keep an eye on them – we want them browned and slightly charred, not incinerated! This should take about 5-10 minutes.

9. Final Touch

Serve up those zucchini kabobs and watch them disappear faster than you can say ‘bottomless pit.’
