How to Make How to Grill Zucchini
Step 1: Prepare the Zucchini
- Cut zucchini into slices, ensuring they are of equal thickness. A mandoline slicer works best for this task. Slicing on the diagonal increases surface area for better grilling.
Step 2: Make the Marinade
- In a bowl, combine the low-sugar vinaigrette with garlic powder and optional dried herbs.
Step 3: Marinate the Zucchini
- Place zucchini slices in a Ziploc bag.
- Pour the marinade over them, ensuring they are well coated.
- Let them marinate in the fridge for at least 4 hours or overnight for more flavor.
Step 4: Preheat the Grill
- When ready to cook, drain the zucchini using a colander placed in the sink.
- Preheat your grill to medium-high heat.
Step 5: Grill the Zucchini
- Optionally spray grill grates with non-stick spray.
- Place marinated zucchini slices diagonally on the grill grates.
- Keep a spray bottle handy in case of flare-ups from dripping oil.
Step 6: Check for Grill Marks
- After about 3-4 minutes, check for grill marks.
- Rotate the zucchini slices in the opposite direction and cook for another 3-4 minutes.
Step 7: Finish Cooking
- Flip zucchini over and cook until slightly charred and softened—about an additional few minutes.
- Total cooking time should be around 10-12 minutes depending on your desired crunchiness.
Step 8: Serve Hot
- Season with salt and fresh ground black pepper if desired before serving hot.
- Enjoy immediately or save leftovers for salads!

Common Mistakes to Avoid
Grilling zucchini can be simple, but mistakes can lead to less-than-perfect results. Here are some common pitfalls to avoid.
- Skipping the marinade: Not marinating zucchini can result in bland flavor. Always let your zucchini soak in a flavorful mixture for several hours to enhance its taste.
- Cutting uneven slices: If the zucchini slices are not uniform, they will cook at different rates. Always aim for even thickness to ensure consistent cooking.
- Overcooking the zucchini: Cooking zucchini too long makes it mushy. Keep an eye on grill time and aim for a tender-crisp texture.
- Not preheating the grill: Grilling on a cold surface can lead to sticking and uneven cooking. Preheat your grill until it reaches medium-high heat before adding the zucchini.
- Ignoring flare-ups: Oil from the marinade can cause flare-ups, burning your zucchini. Keep a spray bottle of water handy to tame any flames that arise.
