Hosting made easy and elegant: let this slow-roasted salmon be the stress-free star of your brunch or buffet.
This slow-roasted salmon recipe, a gem from Samin Nosrat’s acclaimed Salt, Fat, Acid, Heat, has become a favorite in my kitchen. Samin’s method of slow-roasting the salmon is genius—the low heat makes it almost impossible to overcook the fish. In fact, the fish stays tender and slightly translucent, even when fully cooked. As with many of her recipes, Samin provides a general technique for cooking the salmon, along with variations and sauces. I like to pair the salmon with a vibrant French herb salsa, a simple mix of macerated shallots, olive oil, and fine herbs that you can whip up in no time.
Whether served hot, cold, or at room temperature (my favorite), this salmon is always a showstopper, especially at holiday buffets. Plus, the ability to make it ahead of time is a lifesaver for stress-free hosting.
What you’ll need To Make Slow-Roasted Salmon

Step-by-Step Instructions
To begin, 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, which has been preheated to 225°F, 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.) Don’t worry if any white coagulated proteins form on the fish; just scrape them off with a spoon.

Meanwhile, 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.

Break the salmon into large, rustic pieces and spoon the French herb salsa over top.

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!
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!!!
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!
