Oh hey there, welcome to one of our favorite fish recipes ever. Meet our best halibut recipe! This genius way to cook this popular white fish bakes it until flaky and tender with garlic and lemon, along with capers if you love that salty, briny pop. Once it’s juicy and baked, shower it with the secret sauce: finely minced parsley and crispy fried onions, which add a pop of salt, herbaceous flavor and a crunch. You’ll want to use this trick on everything!

Cooking with halibut

Halibut is a popular white fish with firm, meaty flesh and mild, slightly sweet flavor. It is similar to cod or tilapia, but it’s more buttery with a less fishy flavor. Why is halibut so expensive? Wild halibut populations are struggling to compete with demand. Depending on your location, it can cost between $20 to $40 per pound.

Since we live in Midwestern America, we eat halibut as an occasional treat, or of course freshly caught when we’re in Alaska visiting family.

What you need for this baked halibut recipe

If you have a few filets of halibut, baking is a fantastic way to prepare this white fish. It’s also great grilled, but this baked version is our favorite. It’s quick and simple, with just a 15 minute cook time. Here’s what you’ll need for this halibut recipe:

  • For the fish: skin-on halibut filets, fresh or frozen and thawed
  • Seasonings: Olive oil, salt, dried oregano, dried tarragon, red pepper flakes, jarred capers
  • Fresh ingredients: Shallot, garlic, lemon, fresh Italian parsley
  • Special ingredients: Crispy fried onions
  • Equipment: Baking dish: 9 x 13 or 7 x 11

About those crispy fried onions

Crispy fried onions are one of our favorite secrets for adding big flavor to fish, salads, bowl meals, and more! We discovered the idea with our salmon rice crunch bowl, and have been using them ever since! Here are a few tips:

  • Grab a can of purchased crispy fried onions. That’s right, the kind that go on green bean casserole.
  • Chop them along with the parsley to make a garnish. You can chop the onions right along with the parsley, making a crumbly, herby topping.
  • Use them for sprinkling on any bowl meal or salad. They’re especially fun on a salmon rice crunch bowl, a Caesar salad or kale Caesar.

How to make baked halibut

This baked halibut recipe calls for placing the fish in a baking dish with olive oil, salt, and a few aromatic vegetables (shallot, garlic, capers, and lemon) and baking until tender. You can also use this template of a recipe and add your own flavors. Here’s the basic idea for how to make baked halibut:

  • The temperature for baked halibut? 425°F. High heat makes for a perfectly cooked piece of fish. This results in a tasty, tender piece of fish (it won’t have a crispy or seared top).
  • How to season it? We use 1 tablespoon olive oil and ¾ teaspoon salt for 1 ½ pounds halibut. Use more salt to taste if you’re not adding extra seasonings. It’s best baked up with 1 thinly sliced shallot, 2 garlic cloves, thinly sliced lemon rings, and a dusting of dried oregano and tarragon.
  • How long to cook baked halibut? Bake it for 15 to 18 minutes, until flaky. Insert a meat thermometer in the thickest part of the fish: it should read 125°F for medium rare fish (cook to 145°F for well done).

Make it a meal

This baked halibut recipe is a tasty Mediterranean-style meal that will make a fish lover out of anyone! Both seafood afficionados and fish-wary eaters will be wowed by this one, and it’s perfect for a quick weeknight meal or a dinner party to impress. Want to make it into a simple and elegant meal?
