How to Make How to Grill Zucchini
Step 1: Prepare the Zucchini

Step 5: Grill the Zucchini
- Optionally spray the grill with non-stick spray if desired.

- Keep a spray bottle handy in case of flames from dripping marinade.
Step 6: Check and Rotate Slices

Step 7: Finish Cooking
- Flip zucchini over to cook on the second side until slightly charred and starting to soften (about 10-12 minutes total).
Step 8: Serve Hot

How to Perfect How to Grill Zucchini
Grilling zucchini can be easy and delicious with just a few tips. Here are some ways to ensure your grilled zucchini turns out perfectly every time.
- Uniform Thickness: Cut the zucchini into even slices for consistent cooking and grill marks.
- Marinate Longer: Allow the zucchini to marinate for several hours to absorb more flavor from the dressing.
- Preheat Your Grill: Ensure your grill is hot before adding the zucchini to get those beautiful char marks.
- Watch the Time: Keep an eye on the grilling time; overcooked zucchini can become mushy, while undercooked may be too crunchy.
- Use Non-Stick Spray: Lightly spraying the grill helps prevent sticking, making it easier to flip the zucchini without tearing it.
- Season Right Before Serving: Add salt and pepper just before serving to maintain the flavor and texture of the grilled zucchini.

Best Side Dishes for How to Grill Zucchini
Grilled zucchini pairs well with many sides that complement its flavors. Here are some excellent options that will complete your meal.

- Roasted Chickpeas: Crunchy roasted chickpeas provide protein and contrast nicely with soft grilled vegetables.
- Coleslaw: A tangy coleslaw offers crunch and acidity, enhancing the overall meal experience.
Common Mistakes to Avoid
Grilling zucchini can be simple, but some common mistakes can ruin your dish. Here are a few to keep in mind:
Skipping the marinade: Not marinating zucchini can lead to bland flavors. Take the time to let it soak in the vinaigrette and spices for a few hours for the best taste.
Uneven slicing: Cutting zucchini into slices of varying thickness can result in uneven cooking. Aim for uniform slices to ensure they grill evenly.
Not preheating the grill: Grilling on a cold surface can cause sticking and uneven cook times. Always preheat your grill to medium-high before placing zucchini on it.
Overcooking: Leaving zucchini on the grill too long makes it mushy. Keep an eye on it and aim for a tender yet slightly crisp texture.
Ignoring grill marks: Failing to rotate the zucchini for those beautiful grill marks means missing out on the ideal charred flavor. Be sure to turn them after 3-4 minutes.
Serving cold leftovers: Grilled zucchini is best served hot off the grill. While cold leftovers can be tasty in salads, try to enjoy them warm for optimal flavor.
Refrigerator Storage
- Store grilled zucchini in an airtight container.
- It lasts up to 3 days in the refrigerator.
- Allow it to cool completely before sealing to prevent moisture buildup.
Freezing How to Grill Zucchini
- Freeze grilled zucchini in freezer-safe bags or containers.
- For best results, consume within 2-3 months.
- Lay them flat in bags before freezing to save space.
Reheating How to Grill Zucchini
- Oven: Preheat the oven to 350°F (175°C) and bake for about 5-10 minutes until heated through.
- Microwave: Place zucchini in a microwave-safe dish and heat for 30-second intervals until warm.
- Stovetop: Heat a skillet over medium heat and add a splash of oil, then sauté for a few minutes until warmed.
