Olive-Citrus Slow Roasted Salmon
This olive-citrus slow roasted salmon is a tender, flavorful dish that feels elegant but is surprisingly simple to prepare.

It is finished with a bright olive-citrus salsa that brings a mix of briny, sweet, tangy, and herby flavors in every bite.

Ingredients
For the Salmon
1 (1.5 lb) salmon fillet, skin-on recommended
1 navel orange, thinly sliced
1 lemon, thinly sliced
2 tablespoons extra virgin olive oil
1/2 teaspoon kosher salt
1/4 teaspoon cracked black pepper
For the Olive-Citrus Salsa
1/2 cup Castelvetrano olives, pitted and coarsely chopped
Zest and juice of 1 navel orange (about 2 tsp zest, 3 tbsp juice)
2 tablespoons minced shallots or red onion
1/4 cup fresh parsley, finely chopped
3 tablespoons fresh dill, finely chopped
1/4 cup extra virgin olive oil
1 teaspoon Aleppo pepper flakes or 1/4 to 1/2 teaspoon red pepper flakes
1/4 teaspoon kosher salt
Instructions
Prepare the Oven and Salmon
Preheat the oven to 275°F (135°C). Place the salmon fillet on a parchment-lined baking sheet or in a shallow baking dish. Pat it dry gently with paper towels.
Add Citrus and Seasoning
Drizzle olive oil over the salmon and season with salt and black pepper. Arrange thin slices of orange and lemon on top and around the fish, covering it lightly to infuse flavor during roasting.
Slow Roast the Salmon
Bake for 25 to 30 minutes, depending on thickness, until the salmon is just cooked through and flakes gently with a fork. Avoid overcooking to maintain a silky texture.
Make the Olive-Citrus Salsa
In a bowl, combine chopped olives, orange zest and juice, shallots, parsley, dill, olive oil, Aleppo pepper, and salt. Mix gently until well combined. Let it sit for 5 to 10 minutes so flavors can blend.
Serve
Remove salmon from the oven and let it rest for a few minutes. Spoon the olive-citrus salsa generously over the top before serving.
Tips
Use Slow Heat
Cooking at low temperature keeps the salmon moist and prevents dryness.
Choose Fresh Salmon
Fresh, high-quality salmon gives the best flavor and texture.
Do Not Overcook
Remove salmon as soon as it flakes easily; it will continue cooking slightly after removal.
Keep Skin On
Skin helps protect the fish and keeps it tender during roasting.
Slice Citrus Thinly
Thin slices release more aroma and infuse the salmon gently.
Let Salsa Rest
Allowing the salsa to sit helps the flavors blend more deeply.
Use Good Olive Oil
Extra virgin olive oil enhances both richness and freshness.
Balance Salt Carefully
Olives are salty, so adjust seasoning accordingly.
Serve Warm or Room Temperature
This dish tastes great slightly cooled, making it perfect for gatherings.
Add Salsa Just Before Serving
This keeps the flavors bright and fresh.
