This easy slow roasted salmon is cooked at a lower temperature, and topped with a bright, fresh, citrus herb salsa verde. Only 6 ingredients and ready in about 40 minutes!
This slow roasted salmon takes me back to a beach resort in Mexico that used fresh orange juice and fresh herbs to showcase their seafood that was caught that morning and then cooked for dinner. Let's try to imagine that together when we eat this, shall we?
When salmon is slow roasted at a low temperature it ensures that it is cooked perfectly and evenly without drying out. We'll coat it in citrus zest so all of those lovely floral aromas infuse the salmon as it roasts. It's a game changer!
The Italian-style salsa verde is packed with fresh herbs, more citrus zest and juice, and is perfectly balanced, cutting through the richness of the fish with bright flavors.

Ingredients you'll need
In order to showcase the flavor of the roasted salmon itself, you'll only need 6 ingredients that complement it and let that flavor come through.
- Salmon: Choose a salmon fillet from the center of the side, so it's mostly the same width and thickness all the way through to ensure even roasting.
- Oranges and lemons: We are using the juice and the zest for maximum citrus flavor!
- Fresh parsley and cilantro: Speaking of maximum flavor, let's chop the leaves AND the tender stems of the parsley and cilantro. Leaving the stems of herbs behind means leaving flavor behind and we don't want to do that! Also - less food waste. Always a good thing.
- Extra virgin olive oil: It's going to be our cooking oil and the base of the salsa verde.
- Kosher salt
How to make slow roasted salmon
Slow roasted salmon recipe adapted from Bon Appétit.
Step 1: Zest the citrus
Preheat the oven to 250 degrees F. We're gonna roast this salmon low and slow.
Using a Microplane grater, zest 2 oranges and one lemon.
Divide the zest in two and set aside.
Step 2: Make the salsa verde
Chop the herbs finely with a good chef's knife or try using a mezzaluna.
Squeeze the lemon juice and the juice from both oranges into a small bowl.
Add the olive oil, the herbs, and half of the citrus zest, along with a pinch of salt and whisk to combine.

Step 3: Season the salmon
Select a baking dish that fits the salmon fillet but isn't too snug or too big.
Rub the salmon fillet all over with olive oil, season with salt. Pour enough olive oil into the baking dish to just cover the bottom. Lay the salmon skin side down in the dish. Top with the remaining citrus zest.
Step 4: Slow roast the salmon
Slow roast salmon in the oven until it is opaque in the center and flakes easily with a fork, about 25 - 35 minutes.
Note: This is not a medium rare salmon situation. We are cooking it all the way through. You can also use an instant read thermometer to check the internal temperature.
Step 5: Top the salmon with the citrus-herb salsa
Transfer the salmon to a serving plate, top with half of the citrus-herb salsa verde, and serve.
Place the remaining citrus salsa verde on the table so people can help themselves to more.
Expert tips
- If you are using citrus juices in a recipe ALWAYS find a way to also use the zest! I am hard-pressed to think of an example where this wouldn't be true. It magnifies the citrus flavor and aroma. Such a waste to leave it behind.
- When using herbs like parsley and cilantro, use the tender stems as well as the leaves. What are the tender stems? The ones between the leaves and on the top part of the stalks. Same principle as using citrus zest: there is a lot of flavor and aroma. You can save the bottom part of the stems to use in stock.
- Making slow roasted salmon to feed a crowd? It's best to buy a couple of smaller salmon fillets (or cut it) and use two pans as opposed to putting one large filet in one pan. The cooking will be more even for each piece this way.
- Store leftovers in an airtight container in the refrigerator for up to three days. It's best not to reheat slow cooked salmon, to keep it from getting dry. Just serve cold or at room temperature.
Low and slow is the way to go!
Low means cooking at 250 degrees F so the salmon roasts slowly and gently, and retains its moisture. We'll surround it with olive oil to ensure it's evenly cooked and to protect the salmon's silky texture.
When we say slow roasted salmon, we mean slow for salmon, but it's not really that slow. Depending on how you like your salmon cooked, it could take anywhere from 20-35 minutes. That's still a pretty quick dinner!
FAQ
The key to roasting salmon without drying it out is slow, gentle cooking at lower heat, about 250 degrees. This low oven temperature, combined with the olive oil in the pan, ensures that the salmon retains its moisture and has a silky texture once cooked.
Take a fork and press gently on the top of the fillet. If the salmon flakes easily – separating along the lines that run across the fillet – it's done! It should be just opaque in the thickest part, and still appear glossy. (I'm really trying to avoid using the word 'moist' here, people...but there really should be some moisture there.)

Instructions
Salmon
- Preheat the oven to 250 degrees F.

Notes
- If you are using citrus juices in a recipe ALWAYS also use the zest! I am hard-pressed to think of an example where this wouldn’t be true. It magnifies the citrus flavor and aroma. Such a waste to leave it behind.If you don't have a Microplane grater, I highly recommend getting one. They are perfect for zesting citrus as well as grating garlic and ginger.
- When using herbs like parsley and cilantro, use the tender stems as well as the leaves. What are the tender stems? The ones between the leaves and on the top part of the stalks. Same principle as using citrus zest: there is a lot of flavor and aroma. You can save the bottom part of the stems to use in stock.
- I often use a mezzaluna when I have to chop a bunch of herbs. It's sometimes easier and quicker than using a chef's knife.
- I slow roasted this salmon in my Juliska Berry & Thread rectangular baking dish.
