- Ziploc bag
- Grill
- Colander
- Spray bottle (for flames)
Importance of Each Tool

Ingredients
For the Zucchini
- 2 zucchini (see notes)
- 1/2 cup low-sugar vinaigrette (see notes)
- 1 tsp. garlic powder (see notes)
- 1 – 2 tsp. dried herbs (optional)
For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make How to Grill Zucchini
Step 1: Prepare the Zucchini
Cut zucchini into slices, making sure the slices are the same thickness. I like to use a mandoline slicer to slice the zucchini in evenly-thick slices on the diagonal so there is more surface area to touch the grill, but a knife will also be fine.
Step 2: Marinate the Zucchini
Combine the salad dressing with garlic powder and dried herbs of your choice if using. I like this both with and without the extra flavorings. This is one recipe where fresh herbs are not better.
Step 3: Marinate in Fridge
Put zucchini slices into a Ziploc bag, pour in marinade, and let zucchini marinate in the fridge for at least 4 hours or longer—up to all day if desired.
Step 4: Drain Before Grilling
When you’re ready to cook, drain zucchini into a colander placed in the sink. Use a bowl to catch the marinade so it doesn’t go down the drain and discard it.
Step 5: Preheat Your Grill
To cook zucchini, preheat grill to medium-high heat. You can only hold your hand there for about 3-4 seconds. I like to spray the grill with non-stick spray; however, since the marinade has plenty of oil, you may not need it.
Step 6: Grill Zucchini Slices
Place zucchini on grill diagonally to the grill grates while keeping a spray bottle handy for taming any flames that shoot up from oil in the marinade that drips down.
Step 7: Check for Grill Marks
After 3 or 4 minutes, check for grill marks. When you see them, rotate zucchini going in an opposite direction. Cook for another 3 or 4 minutes after you’ve rotated.
Step 8: Cook Until Tender
Turn zucchini to its second side and cook for a few more minutes until it starts to soften with slightly charred and browned outsides. I usually cook zucchini about 10-12 minutes total or slightly less if you want more crunch left in them.
Step 9: Season and Serve
Season with salt and fresh ground black pepper if desired and serve hot. This dish is best when served immediately off the grill. However, whenever I have leftovers, I enjoy cold zucchini in salads!

Common Mistakes to Avoid
Grilling zucchini can be simple, but some common mistakes can ruin your dish. Here are a few pitfalls to watch out for:
- Cutting zucchini unevenly: If your slices are not the same thickness, they will cook unevenly. Use a mandoline or a steady hand to ensure even cuts.
- Skipping the marinade: Marinating adds flavor and moisture. Don’t skip this step; let your zucchini soak in the marinade for at least four hours.
- Overcrowding the grill: Placing too many zucchini slices at once can lead to steaming rather than grilling. Grill in batches if necessary to avoid this mistake.
- Not preheating the grill: A properly heated grill is crucial for achieving those beautiful grill marks and perfect texture. Always preheat your grill to medium-high before cooking.
- Cooking for too long: Overcooking zucchini can make it mushy. Aim for 10-12 minutes total cooking time for a tender yet firm texture.
- Neglecting seasoning: While the marinade provides flavor, don’t forget to season with salt and pepper after grilling for an extra boost of taste.

- It can last up to 3-5 days in the refrigerator.

- It will keep well for up to 3 months in the freezer.
Reheating How to Grill Zucchini
