Tools and Preparation
To make grilling zucchini easy and enjoyable, having the right tools is essential. Here’s what you’ll need:
Essential Tools and Equipment
- Mandoline slicer
- Ziploc bags
- Grill
- Colander
Importance of Each Tool
- Mandoline slicer: Ensures even thickness for zucchini slices, promoting uniform cooking and better grill marks.
- Ziploc bags: Great for marinating your zucchini without any mess while keeping flavors locked in.
- Grill: Provides that distinct smoky flavor we love in grilled vegetables.
- Colander: Helps drain excess marinade efficiently before grilling, preventing flare-ups.

Ingredients
For the Zucchini
- 2 zucchini (see notes)
For the Marinade
- 1/2 cup low-sugar vinaigrette (see notes)
- 1 tsp. garlic powder (see notes)
- 1 – 2 tsp. dried herbs (optional)
How to Make How to Grill Zucchini
Step 1: Slice the Zucchini
Cut zucchini into slices, making sure the slices are the same thickness. A mandoline slicer works well to create evenly thick slices on the diagonal, maximizing surface area for grilling. If you don’t have one, a knife will also do just fine.
Step 2: Prepare the Marinade
Combine your salad dressing with garlic powder and any dried herbs you choose to use. This recipe works well both with or without additional herbs; fresh herbs are often not necessary here.
Step 3: Marinate the Zucchini
Place sliced zucchini into a Ziploc bag, pour in your marinade, and let it marinate in the fridge for at least 4 hours—or even all day if time allows.
Step 4: Drain Before Grilling
When you’re ready to grill, drain the marinated zucchini in a colander set over your sink. Use a bowl underneath to catch any leftover marinade so it doesn’t go down the drain.
Step 5: Preheat Your Grill
Preheat your grill to medium-high heat. You should be able to hold your hand above it for only about 3-4 seconds. Optionally spray non-stick spray on the grill grates; however, there’s enough oil from the marinade that it might not be necessary.
Step 6: Start Grilling
Place zucchini slices diagonally across the grill grates. Keep a spray bottle handy to manage any flames from oil drips.
Step 7: Check for Grill Marks
After about 3-4 minutes, check for nice grill marks. Rotate zucchini slices in the opposite direction for another 3-4 minutes of cooking.
Step 8: Cook Until Tender
Flip zucchinis over to their second side. Cook until they begin to soften and get slightly charred—this usually takes about an additional few minutes.
Step 9: Final Touches
Total cooking time should be around 10-12 minutes; less time if you prefer crunchier texture. Season with salt and fresh ground black pepper as desired before serving hot.
Step 10: Enjoy Leftovers
Grilled zucchini is best served immediately but can be enjoyed cold in salads if you have leftovers!
How to Serve How to Grill Zucchini

As a Salad Topping

How to Perfect How to Grill Zucchini
Grilling zucchini can be simple, but there are ways to make it even better. Here are some tips to ensure perfect results every time.
- Choose fresh zucchini: Look for firm, bright green zucchinis without blemishes for the best flavor and texture.
- Slice evenly: Cut zucchini into uniform slices to ensure even cooking on the grill.
- Marinate longer: Let the zucchini marinate for several hours or even overnight to enhance its flavor.
- Preheat the grill: Make sure your grill is hot before adding the zucchini. This helps achieve nice grill marks and prevents sticking.
- Monitor cooking time: Keep an eye on the grilling process; overcooking can lead to mushy zucchini. Aim for 10-12 minutes total.
- Season well: Don’t forget to sprinkle with salt and pepper before serving for an extra burst of flavor.
Best Side Dishes for How to Grill Zucchini
Grilled zucchini makes an excellent companion for various side dishes. Here are some great options to serve alongside it.
- Grilled Corn on the Cob: Sweet corn complements the smoky flavors of grilled zucchini perfectly.
- Roasted Potatoes: Crispy roasted potatoes add substance and contrast nicely with tender grilled vegetables.
- Quinoa Salad: A light quinoa salad with herbs and lemon provides a refreshing balance to rich flavors.
- Garlic Green Beans: Sautéed green beans tossed in garlic offer a crunchy texture that pairs beautifully.
- Mediterranean Couscous: Fluffy couscous mixed with olives, tomatoes, and cucumbers brings vibrant flavors to your meal.
- Stuffed Bell Peppers: Colorful bell peppers filled with rice, beans, or veggies make a hearty addition to any plate.
- Caprese Salad: Fresh mozzarella, tomatoes, and basil create a classic Italian side that enhances grilled dishes.

Common Mistakes to Avoid
Grilling zucchini can be simple, but a few common mistakes can ruin your dish. Here are some pitfalls to avoid for the best results.
- Bold cutting thickness: Cutting zucchini slices unevenly can lead to inconsistent cooking. Make sure all slices are the same thickness for even grilling.
- Bold skipping marinade time: Not marinating long enough can result in bland zucchini. Allow it to soak in the marinade for at least 4 hours for maximum flavor.
- Bold using high heat too soon: Starting on too high of heat may burn the outside while leaving the inside raw. Preheat your grill to medium-high before cooking.
- Bold overcrowding the grill: Placing too many zucchini slices at once can cause steaming instead of grilling. Grill in batches if needed to ensure proper cooking.
- Bold neglecting seasoning: Forgetting to season with salt and pepper after grilling can leave your dish flat. Always add seasoning before serving for enhanced flavor.
