how to make slow roasted salmon

This slow-roasted salmon recipe comes from the much-acclaimed cookbook Salt, Fat, Acid, Heat by Samin Nosrat. Samin is also the host and producer of the wonderful Netflix cooking/travel docuseries, Salt, Fat, Acid, Heat, based on her book. She writes that slow-roasting is her favorite way to cook salmon because the low heat makes it almost impossible to overcook the fish. Indeed, the heat is so gentle that the fish still appears slightly translucent even when fully cooked.

Like with many of her recipes, Samin gives a general technique for cooking the salmon and then suggests variations and an array of sauces that work with it. I chose to pair the salmon with an elegant French herb salsa made with macerated shallots and fine herbs. While the dish can be served hot or cold, I think it’s best at room temperature as an alternative to poached salmon. It’s perfect for a holiday brunch or buffet.

What you’ll need To Make Slow-Roasted Salmon

How To Make Slow-Roasted Salmon

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.

Reviews & Comments

  • This was such a good way to cook salmon – it came out perfectly, even though I warned my family it was a very low oven temperature so expect it might be a bit translucent (which it actually wasn’t). So easy to leave in the oven like that and salmon was moist, flaky, succulent – absolutely delicious – and the herb dressing was a hit with my fussy kids who often pick off herbs if left as large leaf format! Cold leftover with flatbreads for lunch the next day was relish too. Definitely making this again – so simple, fresh and healthy. Now scanning your website for what to cook next, seems a fantastic site.

    • I think you could, but they wouldn’t take as long to cook so keep a close eye on them. Please LMK how it turns out if you try it!
