Halibut on a weeknight sounds like it should come with a white tablecloth and a 45 minute cleanup. Nope. This is the kind of classic fish dinner that feels restaurant-level but behaves like a Tuesday. We keep it simple: a hot pan, a straightforward seasoning, and a lemon butter sauce that hits all the right notes without turning your kitchen into a science lab.

The goal is flaky, pearly fish with crisp edges and a sauce you will want to drag across the plate with whatever carb is closest. If you have 20 minutes and a skillet, you are in business.

Why It Works

  • Fast, high reward: Halibut cooks quickly, so dinner lands on the table in under 25 minutes.
  • Classic flavor path: Butter, lemon, garlic, and parsley keep it familiar without heavy breading or complicated marinades.
  • Crisp edges, tender center: A properly heated pan and a light flour dusting help you get that golden crust while the fish stays moist.
  • Sauce that forgives: If your pan runs hot or the butter browns a bit, it turns into a nutty, delicious brown butter moment.

Storage Tips

Halibut is at its absolute best right after cooking, but leftovers can still be really good if you treat them gently.

Refrigerator

  • Cool leftovers, then store in an airtight container for up to 2 days.
  • Store fish and sauce separately if you can. The sauce can soften the crust.

Reheating (low drama)

  • Skillet: Warm a little butter or olive oil over low heat, then reheat the fish gently 2 to 4 minutes, flipping once.
  • Oven: Cover and warm at 275°F for 10 to 15 minutes until just heated through.
  • Microwave: Use 50% power in short bursts. It works, but it is the fastest route to dry fish.

Freezer

  • I do not recommend freezing cooked halibut for texture reasons. If you must, wrap well and freeze up to 1 month, then thaw overnight in the fridge and reheat gently.

Common Questions

How do I know halibut is done?

It should turn opaque and flake easily with a fork. If you have an instant-read thermometer, 125°F to 130°F in the thickest part gives you a moist, tender result (think “medium”). If you prefer to follow USDA guidance for fin fish, cook to 145°F. Either way, halibut dries out fast, so start checking early and pull it as soon as it is where you want it.

Can I bake this instead of pan-searing?

Yes. Bake at 400°F until the fish flakes and reaches your target temp, usually 10 to 18 minutes depending on thickness. (For 1 to 1 1/4 inch fillets, expect the longer end of the range.) Make the lemon butter sauce on the stove and spoon it over at the end.

Do I have to use flour?

No, but a light dusting helps with browning and gives the sauce something to cling to. If you are gluten-free, use rice flour or just skip it and sear directly.

What is the best halibut to buy?

Look for thick, moist-looking fillets with a clean ocean smell, not fishy. Fresh is great, but good-quality frozen halibut (thawed in the fridge overnight) can be excellent for weeknights. Most halibut is sold skinless, but it is worth running your fingers over the fillet to check for pin bones.

My fish stuck to the pan. What happened?

Usually one of two things: the pan was not hot enough, or you tried to flip too soon. Let the crust form, then it releases more easily. Also make sure the surface of the fish is dry before it hits the pan.

The first time I cooked halibut at home, I treated it like it was made of glass. Low heat, too much poking, and a lot of hoping. The result was fine, but it did not have that restaurant snap. Once I learned to dry the fish, trust a hot pan, and finish with a simple lemon butter, everything clicked. Now it is my favorite move when I want dinner to feel special without turning a weeknight into a project.
