Save Thin zucchini slices are brushed with olive oil and grilled until tender with charred edges. A mix of grated Parmesan, panko, garlic and red pepper flakes is sprinkled on in the final minute to melt and form a golden crust. Finish with chopped parsley and basil for freshness. Broil briefly for extra crispness and serve hot with a squeeze of lemon for brightness.
The smell of garlic hitting a hot grill grate on a June evening is enough to make anyone stop what they are doing and wander toward the backyard.
My neighbor once watched me make these through the fence and within minutes appeared at my door with a plate of tomatoes as a trade.
Ingredients
- 3 medium zucchini: Slice them a quarter inch thick lengthwise so they hold their shape on the grill without falling through the grates.
- 1/2 cup freshly grated Parmesan cheese: Grate it yourself from a block because pre grated Parmesan has anti caking powder that prevents a good melt.
- 2 tablespoons panko breadcrumbs: These are optional but they add a crunch that takes the crust from good to unforgettable.
- 2 tablespoons olive oil: Use a good quality oil here since it coats the zucchini directly.
- 2 tablespoons fresh parsley: Chop it right before serving so the color stays bright green.
- 1 tablespoon fresh basil: Tear it or chop it gently to release the aroma without bruising the leaves.
- 1 garlic clove: Mince it as finely as you can so it distributes evenly through the topping.
- 1/2 teaspoon sea salt: Zucchini needs salt to draw out moisture and season from within.
- 1/4 teaspoon black pepper: Freshly ground always gives a warmer flavor.
- 1/4 teaspoon red pepper flakes: Optional but a tiny pinch wakes up every other flavor on the plate.
Instructions
- Fire up the grill:
- Preheat to medium high around 400 degrees Fahrenheit and let the grates get fully hot so the zucchini gets those beautiful charred lines.
- Oil the slices:
- Brush both sides of each zucchini slice with olive oil using a basting brush and do not be shy about it because this is what prevents sticking.
- Build the topping:
- Stir together the Parmesan, panko, garlic, salt, pepper, and red pepper flakes in a small bowl until evenly mixed.
- Grill until tender:
- Lay the zucchini directly on the grates or in a grill basket and cook three to four minutes per side until you see deep grill marks and the flesh yields when pressed.
- Add the crust:
- Sprinkle the Parmesan mixture over the zucchini during the last minute, close the lid briefly, and let the cheese soften into a golden layer.
- Finish with herbs:
- Pull the zucchini off the grill and scatter the fresh parsley and basil over the top immediately so the heat releases their fragrance.
Save There was a Sunday when I made a double batch thinking I would have leftovers for lunch the next day and every single slice disappeared before the main course even hit the table.
Getting That Crust Right
The broiler is your backup plan if the grill alone does not crisp the cheese enough.
Herb Swaps That Work
Dill brings a cool Scandinavian feel while oregano pushes the flavor closer to a Greek taverna.
Serving Ideas And Final Thoughts
A squeeze of lemon over the top right before eating adds a brightness that makes each bite feel lighter than the last.
- These pair beautifully with grilled chicken or fish.
- Try them on top of a grain bowl for a quick lunch.
- Serve them immediately because the crust softens as it sits.
Save Keep this recipe in your back pocket all summer long because once people taste it they will ask you to make it again.
Recipe Questions & Answers
- → How thick should I slice the zucchini?
-
Slice zucchini about 1/4 inch thick lengthwise to achieve a tender interior with good char without letting it collapse on the grill.
- → Can I use a grill pan instead of an outdoor grill?
-
Yes. A hot grill pan gives similar char and cooks quickly; brush the pan with oil and work in batches so slices sear rather than steam.
- → How do I get the Parmesan crust extra crisp?
-
Sprinkle the cheese mixture during the last minute of cooking and close the lid if possible to melt and brown; finish under a hot broiler for 1–2 minutes if you want more crunch.
- → What are good cheese alternatives?
-
Pecorino Romano or aged Manchego provide similar salty, nutty notes. For a dairy-free option, use a firm vegan grated cheese and allow a bit more browning time.
- → Can I prepare components ahead of time?
-
Yes—grate the cheese, mix the coating and chop the herbs in advance, but keep zucchini uncoated until grilling to preserve texture and prevent sogginess.
- → Which herbs and seasonings pair best with this dish?
-
Parsley and basil add bright, fresh notes; you can swap in dill, chives or oregano. A squeeze of lemon just before serving lifts the flavors.
