Sous vide is the secret to perfectly cooked halibut every single time. By holding wild Alaskan halibut at a precise 130°F, you achieve a flaky-yet-tender texture that's almost impossible to replicate with traditional methods. Finished with a classic French brown butter sauce with capers and lemon, this keto-friendly dish delivers fine-dining elegance with minimal hands-on effort.

Ingredients

  • 4 wild Alaskan halibut portions (6 oz each), thawed
  • 2 tablespoons extra-virgin olive oil
  • 4 tablespoons unsalted butter
  • 2 tablespoons capers, drained
  • Juice of 1 lemon
  • 2 sprigs fresh thyme
  • Salt and freshly ground black pepper
  • Fresh parsley, chopped, for garnish

Instructions

  1. Set up sous vide bath: Fill a large container with water and set your immersion circulator to 130°F (54°C).
  2. Bag the halibut: Season halibut with salt, pepper, and a drizzle of olive oil. Place each portion in a vacuum-seal bag with a sprig of thyme. Seal using the water displacement method or a vacuum sealer.
  3. Cook sous vide: Submerge bags in the water bath and cook for 40-45 minutes at 130°F. The halibut will be perfectly translucent and flaky.
  4. Sear (optional): Remove halibut from bags and pat very dry. Heat a cast iron skillet over high heat with a splash of oil. Sear each portion for 30-45 seconds per side for a golden crust.
  5. Make brown butter sauce: In the same skillet over medium heat, add butter and swirl until it turns golden brown and smells nutty (about 2 minutes). Add capers and lemon juice; swirl to combine.
  6. Plate and serve: Place halibut on warmed plates, spoon brown butter and capers over each portion, and garnish with fresh parsley.

Chef's Tips

  • 130°F is the sweet spot for halibut: tender and moist without being raw or overdone.
  • The sear is optional but highly recommended. It adds texture contrast and visual appeal.
  • Watch the brown butter carefully. It goes from brown to burned in seconds. Remove from heat as soon as it turns golden and fragrant.
  • You can hold sous vide halibut in the bath for up to 30 extra minutes without overcooking.
