Ingredients

  • 1 large salmon fillet (about 1.5 lbs)
  • 1 bulb fennel, thinly sliced
  • 1 orange, thinly sliced
  • 1 lemon, thinly sliced
  • 1 tablespoon olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon red pepper flakes (optional, for a slight kick)
  • Fresh dill or parsley for garnish

Instructions

Step 1: Preheat and Prepare

  1. Preheat your oven to 275°F (135°C). This low temperature is key to achieving a tender and flaky texture for the salmon.
  2. Line a large baking sheet with parchment paper or lightly grease it with olive oil to prevent sticking.

Step 2: Slice the Ingredients

  1. Cut the fennel bulb in half lengthwise. Remove the tough core from each half by making a small V-shaped cut.
  2. Lay each half flat and slice it thinly into crescent-shaped pieces.
  3. Wash the orange and lemon thoroughly. Slice them into thin rounds, about ⅛ inch thick, ensuring you remove any seeds to prevent bitterness.

Step 3: Arrange the Base

  1. Evenly spread the sliced fennel across the prepared baking sheet, creating a base that will provide both flavor and moisture during roasting.
  2. Layer half of the citrus slices over the fennel, slightly overlapping them so that the salmon absorbs their juices while cooking.
  3. Drizzle half of the olive oil over the fennel and citrus mixture, ensuring even distribution.
  4. Sprinkle a light pinch of salt and black pepper over the fennel and citrus to enhance their natural flavors.

Step 4: Prepare the Salmon

  1. Use paper towels to pat the salmon fillet dry on both sides. Removing excess moisture helps the seasonings stick and allows for better roasting.
  2. Place the salmon, skin-side down, on top of the fennel and citrus base, making sure it’s centered for even cooking.
  3. Evenly rub the minced garlic over the surface of the salmon, pressing gently to ensure it adheres.
  4. Season the fillet with the remaining salt, black pepper, and red pepper flakes (if using) for an extra depth of flavor.
  5. Drizzle the remaining olive oil over the salmon, rubbing it gently to coat the entire surface and lock in moisture.

Step 5: Add the Citrus Topping

  1. Take the remaining citrus slices and layer them over the salmon fillet, covering as much of the surface as possible.
  2. Lightly press the citrus slices onto the fish to ensure they stay in place during roasting and infuse their juices into the salmon.

Step 6: Slow-Roast the Salmon

  1. Carefully place the baking sheet in the preheated oven on the middle rack.
  2. Allow the salmon to roast undisturbed for 30–40 minutes. Avoid opening the oven frequently to maintain an even temperature.
  3. After 30 minutes, check for doneness by inserting a fork into the thickest part of the fillet. If the salmon flakes easily, it’s done.
  4. For precise doneness, use an instant-read thermometer. The internal temperature should read 120–125°F (49–52°C) for medium-rare or 130°F (54°C) for a firmer texture.
  5. If the salmon needs additional cooking, return it to the oven for another 5 minutes and recheck the temperature.

Step 7: Rest and Garnish

  1. Remove the salmon from the oven and let it rest on the baking sheet for 5 minutes. This helps the juices redistribute, ensuring a moist and tender texture.
  2. Carefully transfer the salmon to a serving platter, using a wide spatula to keep it intact.
  3. Sprinkle freshly chopped dill or parsley over the salmon for a vibrant, herbaceous finish.
  4. Optionally, drizzle a little extra virgin olive oil on top for added richness.

Serving Suggestions

  • Serve with a side of roasted vegetables or a simple arugula salad to keep it light and fresh.
  • Pair it with a citrusy white wine like Sauvignon Blanc or a crisp rosé.
  • For a heartier meal, serve over quinoa, couscous, or roasted potatoes.
  • Add a dollop of Greek yogurt or a lemon-dill sauce on the side for an extra layer of creaminess.
