Make the macadamia crust mixture.
1.In a small bowl, combine the finely chopped macadamia nuts, panko breadcrumbs, lemon zest, and minced garlic.2.Pour in the melted butter and stir until the mixture resembles wet sand.3.Season with a pinch of salt and a pinch of black pepper.TIPChop the macadamia nuts by hand with a sharp knife instead of a food processor — this gives you better control and prevents turning them into nut butter. - prep
Season and coat the halibut fillets.
1.Pat the halibut fillets completely dry with paper towels.2.Season both sides of each fillet lightly with a pinch of salt and a pinch of black pepper.3.Brush the top side of each fillet generously with dijon mustard.4.Press the macadamia crust mixture firmly onto the mustard-coated side, dividing it evenly among the 4 fillets.TIPThe mustard acts as both a flavor enhancer and the glue that holds the crust on — don't skip it or the nuts will slide off. - fry · ~3 min
Sear the halibut crust-side down.
1.Heat the olive oil in an oven-safe skillet over medium-high heat until shimmering but not smoking.2.Carefully place each fillet in the skillet, crust side down, and sear without moving for 3 minutes until the crust is deeply golden and set.TIPResist the urge to move or lift the fish during the sear — the crust needs uninterrupted contact with the hot pan to form a golden shell. - bake · ~10 min
Flip and transfer to the oven to finish cooking.
1.Using a thin spatula, gently flip each fillet so the crust side is facing up.2.Transfer the skillet to the preheated oven and bake for 8 to 10 minutes until the halibut is opaque and flakes easily with a fork.TIPHalibut is done at an internal temperature of 130–135°F (54–57°C). It will carry over a few degrees after leaving the oven, so pull it just before it hits 135°F for the most tender result. - garnish
Finish and serve.
1.Squeeze the juice from half the lemon over the fillets while they're still hot.2.Garnish with fresh chopped parsley and serve immediately with lemon wedges on the side.
