Halibut Collars with Onions and Garlic

California cooking likes brightness, fast finishes, and produce that keeps the plate from feeling heavy. This version uses Onions and Garlic and a hot pan finish finish so the Halibut Collars stays central instead of getting buried under the rest of the plate.

1 1/2 to 2 pounds Halibut Collars
Kosher salt
Black pepper
Neutral oil or rendered fat
1 to 2 cups Onions
1 to 2 cups Garlic
Optional: 1 small Thyme
1 tablespoon butter

Trim and season the Halibut Collars while you prep the Onions and Garlic.
Set up the pan, pot, or oven before you start cooking so the timing stays calm once the protein goes down.
Use high heat for the first color, then settle the pan down before the last minute gets away from you.
Fold in the Onions and Garlic at the right point so they support the cut instead of dissolving into the background.
Rest or hold the protein briefly, then serve while the pan juices or broth still feel connected to the plate.

Keep the seasoning clean and let the cut set the pace. Leftovers keep best when cooled quickly and packed shallow; California meals built around Halibut Collars are usually stronger on day one than after repeated reheats.
