Halibut with Spring Onion and Summer Squash Saute

Preparation

1. Step 1

   Cut onion bulbs in half lengthwise (quarter if large). Cut enough onion tops into 2" lengths to measure 1 cup. Heat 1 tablespoon oil in a large skillet over medium-high heat until almost smoking. Add onion bulbs, cut side down; cook until golden, about 3 minutes. Transfer to a plate.

   Step 2

   Heat 1 tablespoon oil in same skillet. Add squash; cook, stirring occasionally, until golden brown and just tender, about 5 minutes. Stir in onion bulbs, 1 cup onion tops, and 1 tablespoon thyme leaves; season with salt and pepper and cook until onion tops wilt, about 1 minute longer. Remove from heat; set squash mixture aside.

   Step 3

   Heat remaining 2 tablespoons oil in a large nonstick or cast-iron skillet over medium-high heat. Season halibut with salt. Add fish and thyme sprigs to skillet and cook until fish is golden brown, about 5 minutes. Turn fish and cook until just cooked through and opaque in the center, about 2 minutes longer. Divide onion-squash sauté among plates; top with halibut.
