kcalIngredients
3 medium zucchini (firm, bright green)
1.5 tablespoons extra-virgin olive oil
3/4 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1/2 teaspoon garlic powder (or 1 small clove, finely grated)
Optional finishers: lemon zest, red pepper flakes, grated Parmesan, chopped fresh parsley or basil, balsamic glaze
Step-by-Step Instructions
- Preheat the grill: Heat a gas or charcoal grill to medium-high (about 425–450ºF). For stovetop, preheat a grill pan over medium-high until hot.
- Slice the zucchini: Trim ends and cut lengthwise into 1/4-inch slices. Thicker slices stay firmer; thinner ones char faster. Aim for uniform thickness.
- Season smart: In a bowl, toss slices with olive oil, salt, pepper, and garlic powder. Coat evenly but don’t drown them—too much oil equals flare-ups.
- Clean and oil the grates: Brush the grill grates and lightly oil with tongs and a folded paper towel. Sticky zucchini is a mood killer.
- Grill time: Lay slices across the grates. Cook 2–3 minutes per side until char marks appear and the zucchini is tender with a tiny bite. Flip once. Don’t fuss.
- Finish with flair: Transfer to a platter. Add lemon zest and a squeeze of juice, a sprinkle of Parmesan, a crack of pepper, or a drizzle of balsamic. Choose your vibe.
- Serve immediately: They’re fantastic hot, but also surprisingly great at room temp. Try not to eat half before they reach the table—challenge accepted.

Best Ways to Store
- Fridge: Store cooled slices in an airtight container up to 3 days.
Layer with parchment if stacking.
- Reheat: Quick skillet reheat over medium with a drop of oil, 1–2 minutes per side. Or air-fry at 375°F for 3–4 minutes.
- Serve cold: Toss leftovers into salads, wraps, or grain bowls.
Cold grilled zucchini is low-key elite.
- Freezing: Not recommended—texture turns mushy. Fresh is best.
Health Benefits
- Low calorie, high volume: You get a full plate for minimal calories—great for satiety without the food coma.
- Micronutrient-rich: Zucchini brings vitamin C, potassium, and antioxidants like lutein and zeaxanthin, which support eye health.
- Fiber and hydration: Its water and fiber help digestion and keep you feeling full.
Hello, balanced snacking.
- Heart-smart fats: Olive oil adds monounsaturated fats that support cardiovascular health.

Things to Be Careful About
- Overcooking: Mushy zucchini is a tragedy.
Pull them when they’re just tender with distinct grill marks.
- Uneven slices: Inconsistent thickness = some burned, some underdone. Use a steady hand or a mandoline (carefully!).
- Too much oil: Causes flare-ups and greasy texture.
Light gloss, not a bath.
- Underseasoning: Zucchini is mild. Don’t be shy with salt, acid, or umami-rich finishers.
- Sticky grates: Clean and oil the grill to avoid losing half your slices to the grate gods.
Different Ways to Make This
- Italian-style: Finish with lemon zest, shaved Parmesan, and chopped basil.
Maybe a drizzle of good balsamic.
- Spicy kick: Add red pepper flakes pre-grill and finish with a squeeze of lime and a dusting of smoked paprika.
- Garlic-herb: Toss with minced garlic, thyme, and parsley after grilling to keep flavors bright.
- Middle Eastern vibes: Finish with za’atar and a spoon of labneh or tahini sauce.
- Cheesy upgrade: Sprinkle grated Pecorino or Parmesan the second they come off the grill so it melts on contact.
- Citrus-forward: Lemon and orange zest together = surprisingly addictive.
- Marinated version: Mix olive oil, lemon, garlic, and oregano; marinate slices 15 minutes before grilling for extra punch.
FAQ
Can I make this without a grill?
Yes. Use a hot grill pan or cast-iron skillet on the stove.
You’ll still get char and caramelization. A broiler works, too—place slices on a sheet pan and broil 2–3 minutes per side.
How thick should I slice the zucchini?
Aim for 1/4-inch thick.
Thinner slices cook super fast and can go limp; thicker slices hold texture but may need an extra minute. Consistency is key.
Do I need to salt the zucchini in advance?
Not required for quick grilling.
Pre-salting and patting dry can help if your zucchini is very watery, but for this recipe, a straight toss-and-grill approach works great.
What oil is best?
Extra-virgin olive oil brings flavor and handles medium-high heat well. If you’re going blazing hot, use light olive oil or avocado oil for a higher smoke point.
Can I prep this ahead?
Yes—slice and season up to 4 hours ahead, then grill right before serving.
Leftovers keep well and are clutch for last-minute salads and wraps.
How do I keep them from sticking?
Preheat properly, clean the grates, oil the grates lightly, and don’t move the slices too soon. Once seared, they release easily.
Patience beats prying, FYI.
What proteins pair well with this?
Grilled chicken, steak, salmon, shrimp, or halloumi love this. It’s also great alongside burgers or tucked into a veggie sandwich with hummus.
