Instructions
Grate the garlic on a microplane directly into a small bowl. Add the lemon juice and whisk. Let sit 2 minutes.
Add the Greek yogurt, tahini, 2 tablespoons cold water, salt, and black pepper. Whisk until completely smooth. Sauce should be pourable but thick enough to hold a shape — add more water 1 teaspoon at a time if needed. Set aside.
Slice each zucchini lengthwise into ½-inch thick planks (3–4 per zucchini). Brush both sides with olive oil and season with salt and pepper.
Place a cast iron grill pan over medium-high heat for 4 to 5 minutes until a drop of water sizzles and evaporates instantly.
Working in batches, lay zucchini planks in the pan. Press lightly with a spatula. Cook undisturbed 3 to 4 minutes until deep grill marks form and the planks release easily. Flip and cook another 2 to 3 minutes until tender. Repeat with remaining zucchini.
Spread the sauce across a serving platter using the back of a spoon. Arrange warm zucchini on top.
Sprinkle za'atar, scatter pistachios and torn mint, drizzle with olive oil, and finish with flaky salt. Serve warm or at room temperature.
Notes
Preheat the grill pan fully — 4 to 5 minutes over medium-high. A cold pan steams instead of chars.
Don't flip until the zucchini releases easily. If it sticks, give it another 30 to 60 seconds.
Stir the tahini thoroughly before measuring — oil separates in the jar.
Sauce keeps 3 days refrigerated. Zucchini is best day-of but holds 2 days; reheat gently in a 300°F oven or serve at room temperature.
