Best Butter Poached Halibut Recipes

BUTTER-POACHED HALIBUT

Steps:

• Clarify the butter: Preheat oven to 350 F. In a 4-quart, oven-safe saucepan, melt butter over medium heat and bring to a simmer, 5-7 minutes. Once white foam (milk solids) begins to form on the top, skim it off with a small ladle or spoon. Reduce heat to medium-low and continue skimming the milk solids until the butter is clear. Pour the clarified butter through a cheesecloth-lined strainer to catch the smaller milk solids. Set aside to cool to 155 F.
• Poach the fish: Season the fish on all sides with salt, about ¼ teaspoon per fillet. Gently lower the halibut into the clarified butter so all four fillets are submerged. Place the fish in the oven and bake, uncovered, 8 minutes.
• Assemble the dish: Fish is done when it's firm but not hard to the touch. Use a slotted spoon to remove the fish, drain off the butter, and plate. Serve with lemon wedges, crunchy salt, and dill.

BROWN BUTTER-POACHED HALIBUT WITH CELERIAC PURéE & CAPER CRUMBS

Steps:

• To make the purée, melt a small knob of butter in a saucepan, add the celeriac and cook over a medium-high heat until starting to brown a little, about 5 mins. Pour over the milk and cream, and season well - the celeriac should be just covered, so add more milk if needed. Bring to a simmer, cover and cook for 15 mins or until tender. Drain, reserving the cooking liquid, and transfer to a food processor. Blend until smooth, then sieve into a clean saucepan, pushing the celeriac through with the back of a spoon or spatula. Add a little of the cooking liquid to loosen the purée if needed, and taste for seasoning.
• To make the crumbs, heat a small knob of butter in a frying pan, add the breadcrumbs and cook, stirring, until golden brown. Throw in the capers and cook for 30 secs more. Tip into a bowl and leave to cool a little, then stir through the parsley.
• Heat oven to 140C/120C fan/gas 2. Gently melt the butter in a small ovenproof saucepan or frying pan, big enough for the fish fillets to fit snugly. Once melted, add the shallot, bay leaf and peppercorns. Keep heating until the butter turns a light brown colour and smells nutty. Leave to cool a little. Gently lower the fish fillets into the warm butter, basting any exposed fish, and transfer to the oven. Cook for 3-4 mins, depending on the thickness of the fish, then turn the fillets over and cook for a further 3-4 mins or until just opaque and feeling firm.
• While the fish cooks, reheat the purée and steam the greens. To serve, spoon the purée into the centre of each plate; use the back of the spoon to spread out slightly into a circle. Top with the greens, then carefully place the halibut on top. Drizzle with a little of the poaching butter and scatter with the crumbs.
