• 2 navel oranges, divided: Use their zest and juice to give the salmon a fresh, tangy aroma and juicy moisture.
• 1 lemon: Adds a sharp citrus kick that perfectly complements the sweetness of the oranges.
• 1 (1 1/2-lb.) skin-on salmon fillet: The star of the show, with skin that crisps up during roasting for added texture.
• 1/4 cup + 2 Tbsp. extra-virgin olive oil, divided: This brings richness and helps carry all the flavors while keeping the salmon moist.
• 1 tsp. kosher salt, divided: Enhances the natural flavors without overpowering.
• 1/4 tsp. cracked black pepper: Offers a mild heat and depth to balance the citrus notes.
• 1/2 cup coarsely chopped Castelvetrano olives: Their buttery, slightly fruity taste adds complexity and a satisfying brininess.
• 2 Tbsp. minced shallots or red onion: Provides subtle sweetness and crunch that pairs beautifully with the olives.
• 1/4 cup finely chopped fresh parsley: Brings a refreshing herbal brightness to the dish.
• 3 Tbsp. finely chopped fresh dill: Infuses the salmon with a classic, aromatic flavor that sings with the fish and citrus.
• 1 tsp. Aleppo pepper flakes (or 1/4-1/2 tsp. crushed red pepper flakes): Adds a gentle warmth and slight smokiness without overwhelming the other tastes.

How to Make Olive-Citrus Slow Roasted Salmon Recipe

Step 1: Prep the Citrus and Herbs

Start by zesting one orange and the lemon, then juice both oranges along with the lemon. This mixture will become the vibrant marinade for your salmon. Next, finely chop the parsley, dill, shallots, and olives to prepare the flavorful topping that will elevate the dish.

Step 2: Season the Salmon

Place the salmon skin-side down on a baking sheet lined with parchment paper or foil for easy cleanup. Drizzle 1/4 cup olive oil over the fillet, then sprinkle evenly with half the kosher salt and the cracked black pepper. The initial seasoning ensures the salmon’s natural flavors shine through during slow roasting.

Step 3: Add the Olive-Citrus Mixture

Pour the citrus juice blend over the salmon, then scatter the olive, herb, and shallot mixture evenly on top. Finish with a sprinkle of Aleppo pepper flakes for a subtle touch of heat. This combination infuses the salmon with complex layers of taste that develop beautifully as it cooks.

Step 4: Slow Roast the Salmon

Preheat your oven to a low temperature—around 275°F (135°C). Bake the salmon slowly for approximately 25-30 minutes, or until it flakes easily with a fork but is still moist and tender. The slow roasting method gently cooks the fish, allowing flavors to meld without drying out the delicate meat.

Step 5: Final Drizzle and Rest

When your salmon is out of the oven, drizzle the remaining 2 tablespoons of olive oil and sprinkle the rest of the kosher salt across the top. Let the fish rest for a few minutes before serving; this helps the juices redistribute, ensuring every bite stays juicy and flavorful.

Garnishes

Fresh lemon slices or a sprinkle of additional chopped dill are perfect garnishes to heighten the citrus-herb character. A few extra cracked black peppercorns scattered on top add an inviting aroma and a rustic appeal. These simple touches turn your salmon into a showstopper on the table.

Side Dishes

Pair this salmon with light, fresh sides like a quinoa salad studded with diced cucumbers and cherry tomatoes or roasted asparagus drizzled with lemon olive oil. Creamy mashed potatoes or a wild rice pilaf make wonderful complements that soak up any lingering olive-citrus juices on the plate.

Creative Ways to Present

For a fun twist, serve the salmon atop a bed of lightly dressed arugula or baby spinach, adding a peppery contrast. Wrapping citrus slices around individual portions creates an elegant presentation that emphasizes the dish’s bright flavors. You can also layer thin orange zest ribbons for a colorful, fragrant garnish.

Make Ahead and Storage

Storing Leftovers

Store leftover salmon in an airtight container in the refrigerator for up to 2 days. Keeping the fish chilled promptly ensures freshness while maintaining those wonderful flavors from the olives and herbs.

Freezing

If you want to save the salmon for a longer period, wrap it tightly in plastic wrap and then in aluminum foil before freezing. It can last up to 1 month without significant flavor loss. When ready, thaw overnight in the refrigerator for best results.

Reheating

Reheat the salmon gently in a low oven set around 275°F (135°C) or in a covered skillet over low heat to avoid drying out the flesh. Adding a small splash of orange juice or olive oil while reheating will help retain moisture and flavor.

FAQs

Can I use other types of olives for this recipe?

Absolutely! While Castelvetrano olives are buttery and mild, Kalamata or green olives can add different flavor profiles. Just be mindful of their salt content as you adjust seasoning.

What if I don’t have Aleppo pepper flakes?

You can substitute with crushed red pepper flakes or even smoked paprika for a different but still delightful warmth. The key is to use them sparingly so they don’t overpower the dish.

Is this recipe suitable for meal prep?

Yes! The flavors actually deepen when the salmon is stored overnight, making it a fantastic option for make-ahead lunches or dinners during the week.

Can I cook this salmon on the grill instead of oven roasting?

While slow roasting produces the most tender result, you can grill the salmon on indirect heat. Use foil to hold the olive-citrus topping in place and cook gently to avoid overcooking.

How do I know when the salmon is done?

Salmon is perfectly cooked when it flakes easily with a fork but still feels moist in the center. Slow roasting at a low temperature helps you achieve this ideal texture every time.
