Slow Roasted Salmon with Citrus and Capers

This slow roasted salmon with citrus and capers is incredibly moist and silky. The salmon is cooked to buttery perfection and the citrusy sauce with salty capers gives it the bright, zesty flavor that compliments it so well. If there is one salmon recipe to make over and over, this is the one.

INGREDIENTS
 

  • 2 pounds whole salmon fillet
  • 2 tablespoons extra virgin olive oil, divided
  • 2 teaspoons kosher salt, divided
  • 2 tablespoons dijon mustard
  • 2 tablespoons capers, drained
  • 2 large lemons
  • 1 large orange
  • ¼ teaspoon black pepper
  • 2 tablespoons flat-leaf parsley, chopped, for garnish

INSTRUCTIONS

  • Preheat the oven to 225°F. Pat dry the salmon fillet with paper towels then place it on a large baking sheet or in a baking dish. Optionally, you can score the fillet into about 6 portions without cutting all the way through. Rub one to two teaspoons of olive oil all over both sides of the fillet, and sprinkle evenly with one teaspoon of salt.
  • In a small bowl, add the rest of the olive oil and salt as well as the dijon mustard, capers, black pepper, and the juice of one and a half lemons and half an orange. Mix the sauce well until combined. Cut the remaining citrus halves into very thin slices.
  • Pour the citrus caper sauce all over the salmon fillet, making sure it is fully covered and that the slits are filled with sauce too. Arrange the lemon and orange slices all over the salmon.
  • Place the salmon in the oven for about 20 to 25 minutes, or until the thickest part of the salmon flakes easily with a fork. If using a meat thermometer, the thickest part should read 130°F.
  • Let the salmon rest for 5 minutes. Garnish with chopped parsley and serve.

NOTES

Salmon doneness: Please note that cooking salmon at this low of a temperature results in salmon that is still a little translucent in the center. This doesn't mean it is raw, so don't get scared and overcook it. As long as it flakes, you're good. 
Storage: Leftovers should be stored in an airtight container in the fridge up to 5 days.
Reheating: Place leftover salmon in the oven at 275°F until warmed through.
