Elegant Macadamia Nut Crusted Halibut with Fresh Herbs and Coconut Sauce

One of my favorite types of fish to dig into is halibut. The fish itself is light and flaky, and when it’s cooked well, it comes out so tender and moist.

It’s fantastic with a bunch of different flavor pairings, but for me, the ultimate is a preparation that’s inspired by the tropics.

A long time ago, I went to Hawaii for the first time with an ex-boyfriend. His parents brought us along to their timeshare and it was one of the most magical trips. We ate all the fresh fish, and on the last night, his parents treated us to a truly incredible meal.

We sat so close to the water while the sun was setting. It was there that I enjoyed my first piece of macadamia nut crusted halibut. The crunchy exterior paired with the light and flaky fish inside was a combination that completely blew me away.

The flavor of the macadamia nuts really shone in this dish, and there was this delicious tropical sauce on top…

Oh boy, I just gobbled that fish up in about two minutes flat. I then patiently waited as the rest of our party finished their meals and watched the sunset.

It was 100% worth being the first one to finish. I know that sometimes that can be an embarrassing thing to do, but for me, it’s just the sign of a really fantastic meal.

This recipe was inspired by that special meal long ago. I don’t quite remember the exact sauce that was served on the fish I had in Hawaii, but I distinctly remember the combination of nuts and coconut, so that’s exactly what I focused on for this recipe.

A fork breaks of a piece of a nut-crusted halibut fillet, on a white plate in a pool of pale green sauce, with another plate in the background on a dark gray surface with scattered macadamias in soft focus.

First, you have a fresh and nutty crust on the halibut fillets, a combination of macadamia nuts, panko breadcrumbs, and fresh herbs. It’s a really simple flavor combination, so it highlights each ingredient well.

This makes the fillets nice and light, without taking away from the flavor of the actual fish itself.

Then you have a creamy jalapeno coconut sauce to go along with it. This recipe uses coconut milk and jalapenos, with a burst of acid from fresh lime juice. That’s actually all the recipe is, with a dash of salt.

Again, the focus of this dish is to offer something that is fresh, and that really makes the flavor of each ingredient pop on your taste buds. The hint of spice is just the right final touch.

You will feel like you’re sitting on a beach at sunset with every smooth and savory bite of this meal.

I love to serve this fish when I have people coming over, and I know this recipe will seriously impress any guests that you invite to your home as well. They will think that you spent hours on it, but the truth is, it couldn’t be easier to create in your own kitchen.

My biggest piece of advice for this recipe is to be sure to follow the instructions closely, and have all of your ingredients ready before you start cooking. While it’s an easy recipe, it comes together quickly – so if your ingredients aren’t ready, you will risk messing up the dish.

If you follow my simple instructions, you won’t have anything to worry about!

Description

Macadamia nut crusted halibut is one of the easiest elegant seafood dishes to make. You’ll feel like you’re eating on a tropical island.


Ingredients

Scale

For the Sauce:

  • Cooking oil spray
  • 2 jalapenos, seeded and halved
  • 1 cup canned unsweetened coconut milk (not low-fat)
  • 1 Tbsp fresh lime juice
  • 1/2 tsp salt

For the Fish:

  • 4 6-ounce boneless/skinless Pacific halibut fillets
  • 1/2 cup roasted and salted macadamia nuts, chopped
  • 1/2 cup panko breadcrumbs
  • 1 ½ tsp chopped fresh parsley, divided
  • 1/2 tsp chopped fresh chives
  • 1 large egg
  • 1 Tbsp water
  • 2 tsp olive oil or coconut oil
  • 1/2 tsp salt
  • 1/4 tsp freshly ground black pepper

Instructions

  1. Preheat oven to 350˚F and place oven rack in center position.
  2. Grease a baking sheet with cooking oil spray. Place jalapeno halves cut side down on prepared baking sheet. Roast in the oven until the skins are bubbly and are charred in some places, about 10 minutes. Remove from oven and transfer to a zip-top bag. Seal and set aside for 10 minutes. Keep the oven on.
  3. In a small saucepan, bring coconut milk to a gentle simmer over medium heat. Cook, stirring occasionally, until thickened and reduced to 1/2 cup, about 20 minutes. Keep warm on low heat.
  4. Add breadcrumbs and nuts to a food processor, and pulse until a crumbly mixture forms. Add mixture to a shallow, wide-mouthed bowl and stir in parsley and chives.
  5. In a shallow bowl, beat the egg and 1 tablespoon water to make an egg wash.
  6. Season both sides of the fish fillets with salt and pepper.
  7. Dredge each fillet in egg wash, then coat completely in the breadcrumb mixture.
  8. Heat oil in a nonstick oven-safe skillet over medium-high heat. Once the oil is hot and shimmering, add fish to pan.
  9. Saute the fish until golden brown on both sides, about 2-3 minutes per side. Transfer pan to the oven and roast for 5 minutes, until fish is cooked through, golden on the outside, and flaky on the inside. Remove from the oven.
  10. While the fish is cooking, peel the skins off the jalapenos. Add jalapenos to a cleaned out food processor or blender along with the reduced coconut milk, lime juice, and 1/2 teaspoon salt. Blend until smooth.
  11. Divide the warm coconut sauce between four plates. Place a halibut fillet on each plate and garnish with freshly chopped parsley. Serve immediately.

Cooking By the Numbers…

Step 1 – Halve Jalapenos, Chop Fresh Herbs, And Measure Remaining Ingredients

Halve and remove the seeds from two jalapenos.

Chop enough parsley leaves until you have about 1 1/2 teaspoons total.

Chop enough chives until you have 1/2 teaspoon total.

Measure out all of the remaining ingredients as listed on the ingredients list.

Note that before you measure out the coconut milk, you should shake the can vigorously to break up any fat solids that have formed in the can.

If any solids remain when you open the can, simply pour all of the coconut milk with the solids into a bowl and whisk until combined. No solids should remain. Measure out 1 cup and continue with the recipe.

Preheat your oven to 350˚F. Place a rack in the center position of the oven.

Grease a rimmed baking sheet with cooking oil spray.

Step 2 – Roast Jalapenos

Place the jalapeno halves on the baking sheet cut side down.

Roast in the oven, until the skins are charred in some places and bubbly. This will take about 10 minutes.

Remove the pan from the oven and transfer the jalapenos to a zip-top bag. Seal and set aside.

Keep the oven on.

Step 3 – Reduce Coconut Milk

Add the coconut milk to a small saucepan over medium heat, and bring to a gentle simmer.

Cook, stirring occasionally, until thickened. The mixture should be reduced to 1/2 cup. This will take about 20 minutes. Put a lid on the saucepan and keep warm over low heat.

Step 4 – Coat

In a food processor, combine the breadcrumbs and nuts. Pulse until the mixture is crumbly. Be sure not to overmix, or it will turn into a nut butter and that’s not what we’re going for here!

Add the mixture to a shallow, wide bowl. Stir in 1 teaspoon of the parsley and the chives.

In a separate shallow bowl, whisk together the egg and 1 tablespoon of water.

Season the fillets all over with salt and freshly ground black pepper.

Dredge each fillet in the egg wash, then coat in the breadcrumb mixture.

Step 5 – Cook

Add the oil to a nonstick oven-safe skillet over medium-high heat. Once the oil is shimmering and hot, add the prepared fish fillets.

Cook until golden brown on both sides. This will take about 2-3 minutes per side. Be careful not to overcook the fish at this point.

Transfer the skillet to the oven and bake for 5 minutes, until fish is golden on the outside and cooked through. Remove from the oven immediately.

Step 6 – Make Sauce

Wipe out your food processor canister and wipe off the blade, or get out your high-speed blender.

While the fish is in the oven, peel the skins off the jalapenos. Add the jalapenos, reduced coconut milk, lime juice, and 1/2 teaspoon of salt to your food processor or blender.

Blend until smooth.

Step 7 – Serve

Divide the coconut sauce between four plates. Place a fillet on top of the sauce on each plate.

Garnish with freshly chopped parsley. Serve warm.

What Goes with This Tropical Dinner?

When it comes to deciding what to serve alongside this entree, I love to have something fresh and green. This can be a fresh leafy green salad, green beans, peas, or broccoli.

In addition, you could also serve up roasted or pressure cooked carrots, or even roasted red potatoes. I just recommend serving something with a pop of color, so the entire plate isn’t completely beige.

You eat with your eyes first! And the fresh herb garnish does provide a nice touch, but fresh vegetables will help to take your plating even further.

  1. This was fantastic! My husband caught a 70 pound halibut off the BC coast. I’ve been making different things but this is off the charts delicious. The next time I make it I will use a touch of cornstarch to thicken the sauce a bit, it didn’t seem to reduce in the 20 minutes. We love heat so the sauce also got some cayenne pepper. So delicious. Thank you for sharing this recipe.

  2. This was amazing! So elegant like at a fine dining experience. Excellent flavors. Definitely worth the calories. The coconut milk takes way longer to reduce….more like 40 minutes but not a deal breaker. Definitely company worthy. Impressive to say the least.

  3. I was looking for a take on Roy Yamaguchi’s Macadamia nut encrusted Mahi (which is a staple at his restaurants) and I’m SO GLAD I came across this recipe. First, I prefer halibut to Mahi. Second, I wanted something a lot less complex than what he does with the lobster cream sauce…I really wanted focus on the flavors of the macadamias and the fish. This was absolutely excellent! We’ve made it twice now…the jalapeno and lime balance the coconut sauce perfectly. This also pairs well with jasmine rice and asparagus. One of our new favorite recipes!

  4. If you haven’t already made this, you are missing out on an experience you’ll never forget! A big 5 stars for this!

    I made this as part of our weekly family cook-off (what started as a one-off to have some fun during the pandemic which turned into a weekly challenge). I added ginger (the challenge for the week), and knocked it out of the park and won the challenge. Not only that, but everyone asked for the recipe and My husband asked to make it again for our anniversary next week. This is definitely a new favorite that I can’t wait to whip out to impress and wow guests!

  5. Made this recipe with Snook, as I live in Belize and Halibut not available, I skipped the oven baking of the fillets as the snook fillets did not require it. It was a hit, everyone loved it! Making again tonight. I will spend more time reducing the coconut milk, other than that, no changes.

  6. The reviews are spot on. This is a keeper. Everyone loved it. I didn’t have macadamia so I used pecans and it was delicious! Not a speck left on the plates. I can’t wait to make it again, this time with macadamia nuts. As others mentioned, I also added cornstarch to the coconut milk to hasten the thickening process, although it’s not necessary. Thanks so much for sharing!

  7. Agree with all the great reviews. This recipe makes for a very tasty twist on the traditional mac nut crusted fish dish. I opted to make the sauce ahead of time and microwaved it just just before dinner. It turned out fine. Especially glad I did that since peeling the skins off the jalapeños was a bit harder and more time consuming than I anticipated. Next time I would opt for canned jalapeños and see if that turns out as well.

    • Lorie,

      There is nothing like fresh jalapenos. To make it a little easier; If you have a gas stove, turn the flame on to about med and roast your peppers. Use tongs to rotate the pepper. Then wrap in a paper towel for a few minutes to soften. Unwrap and use the inside of the paper towel to remove the blackened skin, stem, and seeds inside. The little bits of black add such a nice smokey flavor.

  8. Excellent recipe and so easy! I’ve been making macadamia nut encrusted Halibut for years, but this really was outstanding! Much appreciated the sauce being on the thin side to add a little flavor to the rice and kale mixture after it cooked and then spooned a little sauce on top of the fish. I can’t wait to make it again. It’s a keeper!

  9. I made this a few months ago and thought was delicious, I am going to add a couple shakes of fish sauce this time and blend some cilantro into the blender with the sauce.

    Reply
  10. This is fantastic! I also toasted some shredded coconut and sprinkled on top. I think this is now my FAVORITE meal! We have a freezer full of halibut that my husband caught in Alaska and I am always looking for new ways to cook it…. This was a complete HIT!!

  11. Amazing.. This recipe did not disappoint in anyway. I made a few tweaks ( added some salt, pepper, garlic mix to panko mixture) but the coconut sauce put it over the top ( pulled seeds out of jalapeño to make kid friendly). My family of 4 (7&9 yr old) just crushed 2 pounds of fish l.. and my nine year old actually tried the sauce and loved it!! Adults 1 kids 0!

  12. This was so good!!! I am trying to incorporate more fish in my diet but….. I don’t like fish!! Unless it’s fried and covered in a mayonnaise based sauce of course. This was phenomenal! I ate it embarrassingly quickly, similar to your story… but I don’t care! It was amazing! Definitely making again ❤️

    Reply
  13. All I can say is WOW!!! this is amazing! Pretty much full proof!
    I did do half of the jalapeño, but I don’t think it would’ve mattered because you don’t taste spiciness for those who don’t want any spicy.

    • This is a stovetop recipe that’s then gently roasted in the oven. The breading may fall off or you may risk overcooking the fish if this dish is prepared on the grill.
