The slow roasted citrus salmon with herb salad is a low-effort oven dish that gives you tender, flaky fish and a sharp, fresh side in one go. The long, gentle roast at a moderate oven temperature keeps the salmon from drying out while the citrus slices soften and release their oils into the flesh. You end up with a clean, bright plate that works for a weeknight dinner or a relaxed weekend lunch.
What makes this version reliable is the balance of fat, acid, and herb. The salmon’s natural oils carry the orange and lemon notes, and the herb salad cuts through with parsley, dill, and a quick vinegar toss. If you like fish that stays moist rather than turning chalky, this method is worth knowing. If you enjoyed this, our greek salad only is worth trying next. Making this slow roasted citrus salmon with herb salad at home is surprisingly straightforward once you know the key steps.
Why You’ll Love These Slow Roasted Citrus Salmon With Herb Salad
- Even, gentle heat means the fillet stays succulent from edge to center.
- The citrus layer adds aroma without making the fish taste sour or pickled.
- The herb salad is ready in five minutes and needs no special tools.
- One sheet pan handles the salmon, so cleanup stays minimal.
- It scales easily for two or six by adjusting fillet count and pan size.
Ingredients You’ll Need
- 4 salmon fillets (about 150g each, skin on)
- 1 large orange, sliced into 6 rounds
- 1 lemon, sliced into 6 rounds
- 2 tbsp olive oil
- 1 tsp fine sea salt
- 1/2 tsp black pepper
- 1/2 tsp fennel seeds, lightly crushed
- 30g flat-leaf parsley, leaves picked
- 15g fresh dill, fronds picked
- 10g fresh mint, leaves torn
- 1 tbsp red wine vinegar
- 1 tbsp extra virgin olive oil (for salad)
- 1 small shallot, thinly sliced
Ingredient Substitutions
Orange: Replace with 1 large blood orange, sliced into 6 rounds, for a deeper berry-like citrus note. Blood orange is slightly less sweet and more tannic, so the salmon picks up a rosier color and a sharper edge. Keep the same roast time, but watch the slices near the end so they don’t scorch. The slow roasted citrus salmon with herb salad works well for weeknight cooking when time is limited.
Fennel seeds: Use 1/2 tsp crushed coriander seed instead if you want a lighter, lemony warmth. Coriander lacks fennel’s mild licorice tone, giving a cleaner spice that lets the citrus lead. No change to timing or technique is needed for this swap. Storing leftover slow roasted citrus salmon with herb salad correctly keeps it tasting good for days.
Red wine vinegar: Swap for 1 tbsp apple cider vinegar to soften the salad’s bite. Apple cider vinegar is fruitier and less harsh, so the herbs taste rounder rather than tangy. The salad holds the same texture and doesn’t need extra salt. For the best results with this slow roasted citrus salmon with herb salad, read through all the steps before starting.
Dill: Replace with 15g chervil if available for a milder, anise-free green. Chervil wilts faster than dill, so toss the salad just before serving to avoid soggy leaves. The flavor stays delicate and suits the salmon without overpowering it.
Step-by-Step Instructions
- Heat the oven to 150°C / 300°F and line a rimmed sheet pan with parchment. Lay the orange and lemon slices across the center so the fillets will sit on top of them.
- Place the salmon fillets skin-down on the citrus. Brush with 2 tbsp olive oil, then sprinkle with salt, pepper, and crushed fennel seeds. The citrus should peek out around the edges of each fillet.
- Roast for 25–30 minutes until the salmon is opaque at the center and flakes under a fork but still looks moist. The citrus will wrinkle and release syrup-like juices.
- While the fish roasts, combine parsley, dill, mint, and shallot in a bowl. Add 1 tbsp red wine vinegar and 1 tbsp extra virgin olive oil, then toss so every leaf is lightly coated.
- Pull the pan from the oven and let the salmon rest for 5 minutes on the citrus. This settles the juices so the fillets don’t fall apart when lifted.
- Transfer each fillet to a plate with a few citrus slices, then pile the herb salad on top or beside. Spoon any warm pan juices over the fish before serving.
Pro Tips
Use a thermometer to confirm the salmon hits 52°C / 125°F at the thickest point for a just-set, silky result rather than a firm one.
Dry the fillets with a paper towel before oiling so the surface browns instead of steaming under the skin.
Slice the citrus thinly and evenly so the rounds cook at the same rate and don’t burn at the edges.
Learn proper fish doneness cues from The Kitchn if you’re new to low-temp roasting and want to avoid guesswork.
Chill the salad bowl briefly so the herbs stay crisp against the warm salmon when plated.
Common Mistakes to Avoid
Roasting at too high a temperature firms the proteins fast and leaves the center dry; 150°C / 300°F is the range that keeps the fillet tender.
Skipping the rest time makes the salmon break apart because the juices are still migrating through the flesh when moved.
Dressing the herb salad too early wilts the leaves, so always toss it in the last two minutes before plating.
Serving Suggestions
Set the fillets on a wide platter with the warm citrus and a mound of greens for a shared-table feel. A side of Greek salad adds cucumber and tomato crunch that complements the soft fish.
For a grain base, spoon the salmon over pasta salad only if you want a cold contrast, though plain couscous is cleaner. The dish also pairs with Shirazi salad when you want more acid on the table.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 3 days, keeping the herb salad separate so it doesn’t spoil the fish faster. The citrus slices can go with the salmon or be discarded.
Reheat the fillets in a 120°C / 250°F oven for 10 minutes until they reach 63°C / 145°F at the center, which is the safe internal temperature for cooked seafood. Avoid the microwave, which turns the texture rubbery.
The herb salad does not store well; make only what you’ll eat and discard the rest after the meal.
Recipe Variations
Grapefruit Version
Swap the orange for 1 pink grapefruit sliced into 6 rounds to get a bittersweet profile. Grapefruit releases more liquid, so extend the roast by 5 minutes and check that the fillets still flake cleanly. The result is brighter and less sweet than the original.
Spiced Crust
Add 1 tsp smoked paprika to the oil before brushing for a warm, smoky surface. The salmon takes on a deep orange hue and a gentle campfire note that pairs with the lemon. No other change to the method is required.
Herb Swap
Replace mint with 10g tarragon to shift the salad toward a French bistro tone. Tarragon is stronger, so use slightly less and tear it finely to avoid overwhelming the parsley. The plate reads more anise than the base recipe.
Side Pair
Serve with garlic salmon style roasted potatoes if you want a heavier meal, though it changes the citrus focus. The starchy side absorbs the pan juices and makes the plate more filling for guests.
Salad Only
Use the same herb mix over radicchio salad as a standalone starter before the salmon courses. The bitter leaves balance the fish’s fat and make a two-part menu without extra cooking.

Ingredients
Instructions
-
Heat oven and prep pan
Heat the oven to 150°C / 300°F and line a rimmed sheet pan with parchment. Lay the orange and lemon slices across the center so the fillets will sit on top of them, ensuring the citrus covers the middle of the pan evenly.
-
Place and season salmon
Place the salmon fillets skin-down on the citrus. Brush with 2 tbsp olive oil, then sprinkle with 1 tsp fine sea salt, 1/2 tsp black pepper, and 1/2 tsp crushed fennel seeds so the citrus peeks out around the edges of each fillet.
-
Roast the salmon
Roast for 25–30 minutes at 150°C / 300°F until the salmon is opaque at the center and flakes under a fork but still looks moist, reaching a safe internal temperature of 63°C / 145°F. The citrus will wrinkle and release syrup-like juices by the end of the roast.
-
Mix herb salad
While the fish roasts, combine 30g parsley, 15g dill, 10g mint, and 1 small shallot in a bowl. Add 1 tbsp red wine vinegar and 1 tbsp extra virgin olive oil, then toss so every leaf is lightly coated and glossy.
-
Rest the salmon
Pull the pan from the oven and let the salmon rest for 5 minutes on the citrus. This settles the juices so the fillets don't fall apart when lifted off the pan.
-
Plate and finish
Transfer each fillet to a plate with a few citrus slices, then pile the herb salad on top or beside. Spoon any warm pan juices over the fish before serving so the plate stays bright and moist.
