Zucchini was built for the grill. Thick planks, hot grates, a few unbothered minutes per side, and the water that makes it mushy everywhere else turns into char instead.

This is barely a recipe and mostly a method. Once you have it, you will make it every week the grill is lit anyway.

Cut them thick and leave them alone. Zucchini chars beautifully the moment you stop checking on it.

Method

How I make it

  1. 01
    Cut thick planks.
    Slice the zucchini lengthwise into planks a generous ½ inch thick. Thinner and they collapse into the grates; thicker and the middle stays raw while the outside burns. Planks also cannot fall through the way coins do.
  2. 02
    Get the grill properly hot.
    Set up a charcoal grill for direct medium-high heat with the coals spread evenly, or run a gas grill on medium-high with the lid down for 10 minutes. You should only be able to hold your hand over the grates for 3 to 4 seconds.
  3. 03
    Oil and season at the last minute.
    Brush the planks with olive oil on both sides and season with salt and pepper right before they go on. Salting early pulls water to the surface, and wet zucchini steams instead of charring.
  4. 04
    Grill 3 to 4 minutes per side, no fiddling.
    Lay the planks diagonally across the grates and leave them alone until deep grill marks form and they release without a fight, 3 to 4 minutes. Flip once and give the second side 2 to 3 minutes, until just tender with some backbone left.
    Hands laying an oiled zucchini plank diagonally across the grates of a black kettle charcoal grill, other planks already developing grill marks over glowing coals, with long tongs resting on the grill edge.
    Diagonal to the grates, then hands off. The planks tell you they are ready by letting go.
  5. 05
    Dress them warm.
    Pile the planks onto a platter and squeeze the lemon over while they are still hot, so they drink it in. Scatter with torn basil, flaky salt, and parmesan if you are using it. Serve warm or at room temperature.

A note from Anna

The flip test: lift one corner with tongs. If the plank grips the grate, it is not ready; it will let go cleanly once the char has set. And pull them while they still have a little structure. Zucchini keeps cooking on the platter, and the difference between tender and mushy is about one extra minute.

What to serve with it

Round out the table.

  • ·01
    Grilled lemon-herb chicken thighs
    Same grill, same evening.
  • ·02
    Herby summer pasta salad
    Chop the leftover planks straight into it.
Storage & reheating

Keeping the leftovers good.

Fridge: Up to 3 days. Cold grilled zucchini chopped into a grain bowl or pasta salad is a quietly great lunch.

Make ahead: Cut the planks up to a day ahead and keep them dry in the fridge. Oil and season only at the grill.

Freezer: No. Freezing undoes everything the grill just did.
