Slow-Roasted Salmon with French Herb Salsa

Want to impress your guests without stressing? This slow-roasted salmon with fresh herb salsa looks impressive, tastes amazing, and couldn’t be easier. Serve it warm, chilled, or at room temp—whatever works for you.
This slow-roasted salmon recipe, a gem from Samin Nosrat’s acclaimed Salt, Fat, Acid, Heat, has become a favorite in my kitchen. Her method is brilliant—roasting the salmon low and slow makes it almost impossible to overcook the fish. It stays super moist and just a little translucent, even when it’s fully cooked. Like a lot of Samin’s recipes, this one’s more of a technique than a strict formula, and she includes a few variations and sauces to play around with.
I usually serve it with a simple herb salsa—just macerated shallots, olive oil, and a mix of soft herbs. It takes no time at all and adds so much flavor.
You can serve the salmon warm, cold, or at room temp (that’s my favorite), and it always feels a little fancy, especially on a holiday buffet. It’s delicious alongside roasted potatoes, a simple green salad, or roasted asparagus. The fact that you can make it ahead is a huge bonus when you’re hosting.
“So tender – melt in your mouth. The sauce is excellent. Incredibly simple yet beautiful presentation. My new go to salmon recipe.”
What you’ll need To Make Slow-Roasted Salmon
- Salmon Filet: You can ask your fishmonger to remove the skin for convenience. If you don’t, it’s easy to remove once the salmon is cooked; just slide a thin metal spatula between the flesh and skin when serving.
- Extra-Virgin Olive Oil: Used to coat the salmon for moisture and richness, and as the base for the herb salsa.
- Shallot: Adds a mild, slightly sweet onion flavor to the salsa.
- White Wine Vinegar: Provides bright acidity to balance the richness of the salmon and round out the salsa.
- Fresh Italian Parsley, Chervil, Chives, Basil, And Tarragon: A blend of fresh herbs that gives the salsa its bright, fresh flavor and loads of aroma.

Step-by-Step Instructions
Step 1. Prep the salmon. Place the salmon on a baking sheet, drizzle with olive oil, and sprinkle evenly with salt.
Step 2. Roast the salmon. Roast for 40 to 50 minutes in a 225°F oven until the thickest part flakes easily when pressed with a knife or your finger. It will still look a little translucent even when fully cooked.
Pro Tip: Slow-roasting keeps the fish tender, prevents it from seizing up, and reduces the amount of white protein (albumin) that surfaces. If you see a bit (like below), simply scrape it off with a spoon.
Step 3. Macerate the shallots. In a small bowl, combine the shallot and vinegar and let sit for 15 minutes.
Pro Tip: Macerating mellows the sharp bite of the shallot and enhances its natural sweetness.
Step 4. Make the herb oil. In another bowl, mix the herbs, olive oil, salt, and black pepper.
Pro Tip: Chop the herbs as finely as possible so their essential oils release and flavor distributes evenly.
Step 5. Finish the salsa. Right before serving, use a slotted spoon to transfer the shallots (without the vinegar) into the herb oil. Stir, then taste and add 2 to 3 teaspoons of the vinegar, depending on how sharp the flavor is. Adjust salt if needed.
Step 6. Break and serve the salmon. Break the salmon into rustic pieces, spoon the herb salsa over the top, and serve.
The salmon can be roasted a day ahead and refrigerated, and the salsa can be made up to two days in advance and chilled until ready to use.

Ingredients
For the Salmon
- 1 (2-lb) salmon filet, pin bones and skin removed
- 1 tablespoon extra-virgin olive oil
- ¾ teaspoon kosher salt
For the French Herb Salsa
- 3 tablespoons finely diced shallot, from 1 medium shallot
- 3 tablespoons white wine vinegar
- 2 tablespoons very finely chopped fresh Italian parsley
- 1 tablespoon very finely chopped fresh chervil (okay to substitute more parsley if you can't find it)
- 1 tablespoon very finely chopped fresh chives
- 1 tablespoon very finely chopped fresh basil
- 1 teaspoon very finely chopped fresh tarragon
- 5 tablespoons extra-virgin olive oil
- ¼ teaspoon kosher salt
- Freshly ground black pepper
Instructions
For the Salmon
- Preheat the oven to 225°F (105°C) and set an oven rack in the middle position.
- Place the salmon on a baking sheet. Drizzle with the olive oil and sprinkle the salt evenly over top. Slide the pan into the oven and roast for 40 to 50 minutes, until the fish begins to flake in the thickest part of the filet when poked with a knife or your finger. (Because this method is so gentle on its proteins, the fish will appear translucent even when it's cooked.) Using a small spoon, scrape off any white coagulated proteins that may have formed on the salmon.
- Break the salmon into large, rustic pieces and spoon the French herb salsa (below) over top. This dish can be served hot, cold, or room temperature.
For the French Herb Salsa
- In a small bowl, combine the shallot and vinegar and let sit for 15 minutes to macerate.
- In a separate small bowl, combine the herbs, olive oil, salt, and a few grinds of black pepper.
- Just before serving, use a slotted spoon to add the shallot (but not the vinegar, yet) to the herb oil. Stir, taste, and add the vinegar as needed (I usually add 2 to 3 teaspoons). Taste and adjust salt, if necessary.

Living in the Pacific Northwest is so hard. Hah! We have wonderful salmon fishing here and my husband loves to fish – so we know a bit about cooking very fresh, lovely salmon. And, when Copper River salmon is in from Alaska – it is a very special treat! We consider ourselves pretty astute at cooking salmon…and, I had a buffet luncheon that needed a protein dish. Copper River salmon was in at Costco. I looked at your website and thought, why not give this a try – it’s different and sounds wonderfully easy and perfect. And, it was! Easy, perfect and fool-proof ! Everyone loved it! And, I think this may be my favorite way to cook salmon now. I have Samir’s cookbook and am eager to try some of her other ways to season the salmon too. I can’t thank you enough, Jenn, for all of your fabulous recipes and cooking techniques/recommendations. Thank you a million times over!
Such a delicious and easy meal. Yummy for dinner and equally delicious for lunch the next day. I’m a big fan!
One of my favorites! So easy to make and delicious!
This is the best…! I’ve made this cold for a crowd the day before with cold roasted vegetables.
We used to sous vide our salmon to get it to taste like this. This is much easier and absolutely delicious!
Also great for a weeknight meal without the salsa..just some lemon and whatever herbs and spices we have on hand. Always wonderful.
I’ve made this many times – wanted to update my review. Tonight it was about 1 lb of Faroe Island Scottish Salmon. Came out perfect and the herb salsa was an excellent counterpoint to the rich, buttery salmon. My herb salsa was parsley, chives & basil (don’t care for tarragon) and shallots. All around just perfect!! Thanks Jenn!
Made this tonight….so delicious! Don’t miss the opportunity to scoop up the “salsa” with a good piece of bread. 10/10 with the entire family!!!
I made this recipe along with your roasted potatoes and carrots for Easter and my only complaint is that I didn’t make more! This recipe was so easy and turned out beautifully. Everyone raved about the salmon and the fresh herbs salsa was the star of the show. Your recipes never disappoint! Thank you for another winner!
Hi Jenn … what side dishes and dessert would you suggest serving with the salmon.
Hi Janice, what meal do you plan to serve this for?
This was SO good and so easy! I first had at a friend’s house and then made tonight. I’ve already invited other friends over to make again in 2 weeks!
This was the best salmon I have ever made. The only difference is that I added a couple of halved cherry tomatoes to the herb topping. I served with roasted potatoes and asparagus.
This is definitely going on my regular rotation.
