It’s best enjoyed fresh, although it can be frozen for up to one month.

Is confit healthy?

Compared with frying, confit is a gentle cooking method that helps preserve moisture and delicate nutrients while requiring no high-heat browning.

How to confit ocean trout

Recipe by Samantha Gowing

The secret to confit is patience. Never allow the oil to simmer. A gentle temperature between 65–75°C keeps the fish beautifully moist and prevents it from drying out.

Confit ocean trout slowly cooked in olive oil with herbs and citrus, served on a white platter.

Ingredients

Units Scale

For the confit

  • 1.5 litres extra virgin olive oil
  • 2 tablespoons fresh dill sprigs
  • 6 cloves garlic, whole or thinly sliced
  • 1 tablespoon crushed coriander seeds
  • 8 lemon zest strips

For the trout

  • 1 whole side of ocean trout (approximately 1.2–1.5 kg), skin on, pin bones removed

To serve

  • Assorted peppercorns
  • Juice of 1–2 lemons
  • Extra dill leaves (optional)
  • Lemon slices

Instructions

  1. In a very clean, heavy-based large oval casserole dish or preferably a fish kettle, slowly heat the oil and confit infusion ingredients to 60-70 C.
  2. Use a thermometer to insure that you do not heat the oil too high.
  3. Essentially you are creating an oil bath, not a shallow fryer. Confit for 4 minutes skin side up.
  4. Gently flip over so the skin gets a little crisp (do not fry) for a further 4 minutes.
  5. Your fish should still be soft and just rare. Of course, cook further if you prefer.
  6. The colour should go from orange to just pink. Once cooked remove from oil on to a serving platter.
  7. Season with salt, pepper and lemon juice.

Notes

You don’t need to completely submerge a whole side of trout. Place it in a shallow roasting tray or fish poacher and pour the warm aromatic oil over the fish until it comes about two-thirds of the way up the sides. Carefully spoon the oil over the exposed surface during cooking.

Keep the oil at a gentle 65–75°C—it should never simmer or bubble. Cook for approximately 35–45 minutes, depending on the thickness of the fish, until it flakes easily but remains beautifully moist.
