Grilled Zucchini (Smoky, Tender-Crisp)
Grilled zucchini is smoky, tender-crisp summer squash cooked over high heat with a garlicky olive oil marinade, and it comes together in about 20 minutes. Cutting it into planks or thick spears keeps it from falling through the grates and helps it char without going soft.
What Makes This Recipe Work
A short oil and seasoning marinade coats the zucchini so it grills instead of sticking, and a hot, clean grate creates quick char marks before the interior overcooks. Resting it briefly after grilling lets the smoky flavor settle.
Ingredients for Grilled Zucchini (Smoky, Tender
- 4 medium zucchini (about 2 lb / 900 g)
- 2 tbsp olive oil
- 1 tsp kosher salt
- 1/2 tsp freshly ground black pepper
- 1 tsp garlic powder
- 1 tbsp fresh lemon juice, plus wedges for serving
- 2 tbsp chopped fresh basil, parsley, or mint
- Optional: 2 tbsp grated Parmesan or crumbled feta
How to Make Grilled Zucchini (Smoky, Tender
- Heat a grill to medium-high, about 425 to 450 degrees F (220 to 230 C), and scrape the grates clean. Oil them lightly with a paper towel held with tongs.
- Trim the zucchini and cut it lengthwise into 1/4-inch planks, or into thick spears for a heartier bite. Keep the pieces uniform.
- In a large bowl, toss the zucchini with the olive oil, salt, pepper, garlic powder, and lemon juice until coated. Let it sit 5 minutes, no longer.
- Lay the pieces on the hot grill in a single layer and cook undisturbed for 4 to 5 minutes, until well marked on the underside.
- Flip with tongs and cook 3 to 4 minutes more, until tender with a slight bite and charred in spots. Move pieces to a cooler zone if they darken too fast.
- Transfer to a platter, sprinkle with the fresh herbs and Parmesan or feta if using, and rest 2 minutes.
- Serve warm with extra lemon wedges, or at room temperature as part of a spread.
Tips for the Best Grilled Zucchini (Smoky, Tender
- Salt the zucchini just before grilling; salting early draws out water and makes it limp.
- Keep pieces large enough not to fall through the grates.
- Do not move the pieces while they sear, so they develop clear grill marks.
- To saute instead, use the same seasoning in a hot skillet and cook 3 to 4 minutes per side.
Variations and Substitutions
- Sauteed zucchini: cook the seasoned pieces in a hot skillet with a little extra oil for a stove-top version.
- Grilled BBQ zucchini: brush with your favorite barbecue sauce in the last 2 minutes for a sticky glaze.
- Add yellow squash to make a sauteed zucchini and summer squash mix on the grill or in a pan.
- Serve alongside the roasted zucchini recipe or add it to the zucchini recipes collection as a cookout side.
How to Store and Reheat
- Store leftovers in the fridge for up to 3 days; grilled zucchini is good cold in salads or grain bowls.
- Reheat gently in a skillet or on the grill rather than the microwave to keep the texture.

Grilled Zucchini (Smoky, Tender FAQ
How long do you grill zucchini?
About 8 to 10 minutes total over medium-high heat, flipping once. Cook the first side undisturbed for 4 to 5 minutes to get clear grill marks, then finish the second side for 3 to 4 minutes.
How do you cut zucchini for grilling?
Cut it lengthwise into 1/4-inch planks or thick spears so the pieces are large enough to stay on the grates and hold their shape. Keep the cuts uniform for even cooking.
Can I cook zucchini on the grill without it sticking?
Yes. Oil the zucchini and the clean, hot grates, then leave the pieces undisturbed until they release naturally. A light brush of oil on the grates makes the biggest difference.
Can I grill zucchini ahead of time?
Yes. Grill it up to a day ahead, refrigerate, and serve cold or warm gently. It holds up well at room temperature for a cookout or picnic.
