Steps

1. 1

   Begin by halving the onion bulbs lengthwise, or quarter them if they are large. Slice enough of the green tops into 2-inch lengths to yield 1 cup. In a large skillet, heat 1 tablespoon of oil over medium-high heat until it is nearly smoking. Place the onion bulbs in the skillet cut side down and sauté until they turn golden brown, which should take approximately 3 minutes. Once done, transfer the onions to a plate for later use.

2. 2

   In the same skillet, heat 1 tablespoon of oil over medium-high heat. Add the squash and cook, stirring occasionally, until it turns golden brown and reaches a tender consistency, which should take around 5 minutes. Introduce the onion bulbs, along with 1 cup of onion tops and 1 tablespoon of thyme leaves into the skillet. Season with salt and pepper, then continue cooking until the onion tops wilt slightly, approximately 1 minute more. Once done, remove the skillet from the heat and set aside the mixture of squash for later use.

3. 3

   In a large nonstick or cast-iron skillet, heat the remaining 2 tablespoons of oil over medium-high heat. Season the halibut with salt. Place the fish and thyme sprigs in the skillet and cook until the fish turns golden brown, which should take approximately 5 minutes. Flip the fish over and continue cooking until it is just cooked through and appears opaque at the center, this should take about 2 more minutes. Serve by dividing the onion-squash sauté among plates, then topping each portion with a piece of halibut.
