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

Salmon ingredients including olive oil, pinot grigio, and 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.

  • Hi Jenn — I would love to make this herb salsa salmon for Easter but I fear the translucent look will be off-putting to some. I was wonder about cooking the salmon as per your “every day spice crusted salmon” ( not with the spices— just the cooking technique) and topping it with the herb salsa when done. What do you think? Many thanks! Wishing you and yours a Happiest Passover!— princess Barb

  • Amazing — I’m cooking for 30 and think this will be perfect. Regarding cooking times…..
    Question: How do I adjust cooking time based on the weight of each filet?

    Question: I see you recommend leaving skin on …. is there cooking time adjustment for skinless? I find skinless much easier when cooking for a crowd and serving buffet style, better presentation too!

    Question: I have several guests who like their salmon “cooked through” — recommendations on how to prepare NOT translucent?

    So, so grateful for your response!

    • Hi Lisa, Because this cooks on a low temperature for a long time, there won’t be a ton of variation timing-wise based on the weight of the salmon. And for the guests that like their salmon cooked through, I’d just leave a portion in for longer — it will eventually loose it’s translucency. Regarding the skin, I actually call for the the skin to be removed so you’re good there. Hope everyone enjoys it! 🙂

  • This is absolutely gorgeous! I served it with an herby potato salad. Our neighbor could not believe how fabulous it was with the slow-low cooking method.

  • My contribution to the Hannu-Mas dinner is supposed to be salmon and google led me here. This recipe is right up my alley, thank you! I also want to add that your Caesar Salad Dressing has been a go-to for years and my grown son now makes it often.

    • Hi Haze, this would be nice with roasted potatoes and a green veggie — maybe these green beans with shallots. Hope that helps and that you enjoy the salmon!
