How to Cook Halibut in the Oven for Perfectly Flaky, Tender Fish

Halibut is a delicious and healthy fish that takes beautifully to oven cooking. Baking halibut allows you to highlight its mild, sweet flavor with aromatic spices, herbs, and citrus. When done right, the fillets come out tender and flaky on the inside with a lovely golden crust.

Cooking halibut in the oven helps ensure it stays nice and moist unlike cooking over high direct heat which tends to dry out fish. With a few simple tricks you’ll learn how to bake halibut so it turns out succulent and delicious every time.

Choosing Halibut for Baking

• Look for fresh, sashimi-grade halibut fillets at the fish market or grocery store seafood counter. Don’t buy frozen.

• Choose fillets that are translucent white and glistening, without any browning.

• Smell the fish to check for freshness – it should smell like the ocean, not fishy or sour.

• Plan on 4-6 oz of halibut per serving. Buy 1⁄2 to 1 lb total per person.

• Halibut is expensive, so substitute another mild white fish like cod, haddock, or tilapia.

Seasoning and Preparing the Halibut

• Pat the fillets dry with paper towels before seasoning.

• Brush both sides with olive oil This helps the fish bake up tender and moist,

• Lightly season both sides with salt and pepper. Go easy on the salt since halibut is naturally briny.

• Coat with desired herbs and spices, Lemon-herb or Mediterranean flavors work well

• Let the seasoned fillets sit 5-10 minutes so the flavors permeate before baking.

• If the fillets have skin, place them skin-side down on the baking sheet.

Baking Directions for Halibut

Follow these simple steps for perfectly cooked halibut:

• Preheat oven – Heat to 400°F to quickly bake the fish through.

• Prep baking sheet – Line with parchment paper or foil and brush with oil to prevent sticking.

• Bake – Place fillets skin-side down if applicable. Bake for 8-12 minutes until fish flakes easily.

• Rest – Let sit 5 minutes before serving so juices redistribute.

• Check for doneness – Halibut should be opaque throughout when fully cooked.

• Avoid overbaking – Check early and often to prevent drying out.

• Add veggies (optional) – Roast cherry tomatoes, diced potatoes, or summer squash alongside.

Handy Tips for Baked Halibut

• Brush fillets with mayonnaise instead of olive oil for extra browning and moisture.

• Add slices of lemon, lime, or orange on top for bright flavor.

• Bake on a cedar plank for presentation and subtle woodsy aroma.

• Broil the last 1-2 minutes for crisper top browning if desired.

• Stuff the cavity of whole halibut with herbs and citrus slices before baking.

• Microwave or roast garlic and mash into softened butter. Spread over fish before baking.

• Top with Parmesan, feta, or panko breadcrumbs for crunchy roasted texture.

• Roast at a high temp until just done, then switch to low temp if you need to keep it warm.

Mistakes to Avoid

Avoid these common mishaps when baking halibut:

• Overcooking – Check early and often. Halibut goes from perfect to dry and chewy quickly.

• Baking too hot – Above 450°F overcooks the exterior before the center cooks through.

• Uneven cooking – Use fillets of similar thickness so they cook at the same rate.

• Letting sit too long – The fish continues to cook off the heat. Serve immediately or it may dry out.

• Using frozen fish – Thawing causes moisture loss, so always bake fresh fish.

• Insufficient seasoning – Halibut is bland without enough herbs, citrus, spices, salt and pepper.

Serving Suggestions

Baked halibut pairs nicely with:

• Fresh herbs – Dill, parsley, cilantro, basil, mint

• Citrus – Lemon, lime, orange

• Veggies – Asparagus, green beans, tomatoes

• Roasted potatoes or rice

• Salsa, chimichurri, or compound butter

• A crisp white wine like Sauvignon Blanc
