1️⃣ Prep

Pat tilapia very dry. Wash leeks well to remove grit; drain and pat dry.

2️⃣ Coat the Fish

Mix za’atar + salt on a plate. Brush one side of each fillet with olive oil. Press the oiled side into the za’atar to coat heavily.

3️⃣ Char the Leeks

Heat 1 tbsp oil + butter in a skillet over medium‑high. Add leeks in a single layer. Cook 3–4 min without moving until deeply browned.

4️⃣ Sear the Tilapia

Push leeks to the edges. Add remaining oil. Place tilapia crust‑side down. Sear 3 min until fragrant and crusted.

5️⃣ Finish Cooking

Flip fillets. Cook 2–3 more min until opaque and flaky; leeks should be tender.

6️⃣ Serve

Squeeze lemon over the pan to deglaze. Serve fish over charred leeks.
