Slow-Roasted Salmon with French Herb Salsa
This slow-roasted salmon with an elegant fresh herb salsa is wonderful at room temperature, making it perfect for a holiday brunch or buffet.
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.
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.

Delicious!
I just tried this recipe last night and everyone in my family loved it. One question – any suggestions for what to do with all of the herbs that are left over after making the sauce (which was delicious!)?
So glad everyone enjoyed this! There are a number of ways you can use up (or store) fresh herbs. This article gives some details. Hope you find it helpful. 🙂
Made this for dinner party last weekend, a huge hit! Fresh caught sockeye salmon from Costco , slow roasted with herbs from our garden. Delightful summer Dinner our deck.
Jenn has hit another home run. I have not tried any recipe of hers which was not delicious & easy to follow. Just made the plum galette last evening, delicious , easy and wonderful buttery crust.
Thank you for your inspirational recipes!😋
What a superb cooking method! The slow heat method makes for very moist, tasty fish! The herb sauce is a great complimenting taste. My family liked the herb sauce so much they were even using it as salad dressing. It is so fresh and vibrant tasting. Occasionally my husband will smoke the salmon filet which is delicious. The taste and texture was very similar without the smoke flavor which the family gave great reviews. Makes a great meal or can put out as an appetizer since it is just as delicious room temperature as hot.
BEST recipe for salmon ever! This is truly a ‘no-fail’ method and serving at room temperature takes all the pressure off timing and it is just as good as hot from the oven! Will make this over and over again! Love the salsa and so did my husband!
Simply perfect.
Delicious and easy to make. I tucked my salmon into a bed of fresh dill before dressing with oil/salt. Gives the salmon a wonderful flavor, if dill is your thing!
Delicious, and easy and quick to make if you have a food processor to chop all the ingredients. Mine looked just like the picture!
Wow! This was delicious and so easy to make. I love that you can serve it at any temp- it makes it great for a party. My guest enjoyed it! This was my first time working with tarragon. I was surprised how the licorice flavor but it worked well in the dish.
Yikes. Please pardon my typos!
Hi Jenn
Thinking about making this for a card party luncheon starting out with your spring pea and basil soup. I having trouble thinking of what to serve along side the salmon. The herb sauce has a definite taste. What would go with this dish. Hopefully I can make ahead.
Thanks. I love this site. 😍
Lynn
Hi Lynn, I think some steamed potatoes would be nice; I’d use herbs like chives and parsley, which will pair nicely with the salmon. And you can definitely make those ahead. These French string beans or simple roasted asparagus would also go beautifully.
Hi Jenn! I have made this before and love it and would like to now make it for a shower I am hosting. If this is to be more of a side dish in addition to many other dishes for about 15 people, would you double it or keep the same?
Thank you!
Alana
Hi Alana, It’s a close call but I’d double it to be safe (admittedly, I’m always terrified of running out of food!).
Great- Thanks for confirming! I am with you- and with this dish, I know it will go fast!
Alana
I made this for Easter dinner and it was excellent. My guests loved it. The herb sauce made it. The tarragon made it so delicious! I will definitely make the sauce again, it might go well with chicken.
Hi Jenn, I thought I had white wine vinegar but do not. Could I use champagne vinegar, red wine vinegar, rice wine vinegar, distilled white vinegar, or lemon juice?
Hi Janet, No worries, champagne vinegar or unseasoned rice wine vinegar will both work well. Enjoy!
Thank you so much for the quick reply Jenn! The drunken French toast was a fabulous Easter breakfast and can’t wait for the salmon for later!
This ended up fabulous — an easy and perfect dish for the Spring Easter holiday, which we enjoyed outside. Every dish on this blog is a winner.
I’ve made this three times exactly as instructed. Perfect every time and very forgiving. I love how tender the fish is with the slow roast method.
What temperature does the fish have to be in the thickest part to be considered cooked?
Hi Helen, The temp should be 145°F.
If I make this ahead, should I keep the salsa separate and add on before serving?
Yep – hope you enjoy! 🙂
Wow! Thank you for such a speedy reply! The salmon just came out of the oven and salsa is made (which is delicious btw). I can’t wait to try it on the salmon! Thanks, again.
This salmon recipe is one of the best I’ve ever prepared! Unanimous five-star approval from both my family and friends. I served it with oven-baked brown rice and roasted broccoli—rave reviews and so easy for me to prepare. Thank you for this great “go-to” recipe!
This is the easiest and most foolproof way of making salmon! I made this twice now for company and everyone loved it. I served this with the grilled asparagus salad with feta and roasted potatoes. I was able to make everything except the potatoes ahead of time. I served the salmon and salad at room temperature and the potatoes hot out of the oven. To finish, I served strawberry shortcake with creme fraiche/lemon curd topping. So yummy!
Hint – make extra of the salsa because it’s so fresh and tasty! I used it as a salad dressing and on eggs.
Let me start by saying that I am not a fan of salmon or really any type of fish. I’m trying to incorporate more into our diets as it is so good for you. I loved this recipe! I prepared it exactly as written. We had some leftover, so I used it the following day in salmon louie salad which was also wonderful. I served the salad with charred lemon to squeeze over the top! We will certainly have this dish again. It is so versatile and has a lovely flavor. This is one fish dish I am happy to eat!!
Was searching for a new way to present salmon as my daughters love this fish. I followed the recipe exactly as presented and was delighted with the results. It was moist and deliciously flavored – we all enjoyed the taste. I will certainly make this again as it is a winner. Thank you for this presentation of salmon 🙂
Hi,
How long would you cook for just 1lb?
Thank you!
Hi Rose, the cooking time is primarily dependent on the thickness of the fish so it’s likely that if you just have a longer (not thicker) piece of fish it will need to cook for about the same amount of time. I’d suggest starting to check it at about 35 minutes. Hope you enjoy!
Made this for a luncheon………..simple to make, salmon was moist and the herbs were sensational…..everyone loved it. Served it at room temp.
Hi-Looking forward to making this for a small crowd. If made the day before, would you suggest reheating very slightly before serving? Or perhaps bring to room temperature before serving? I think I may prefer reheating but fear overcooking it. I love all your recipes. You make me look like I know what I’m doing.
Hi Robin, So glad you’re having success with the recipes! I actually prefer this dish at room temperature so I wouldn’t reheat it; just bring to room temp. Hope you enjoy it!
OMG!!! This is sooooo good! I have never prepared fish in this way and I was pleasantly surprised! What a delight! So fresh! I really can’t use enough exclamation marks!!! If you use Sockeye definitely reduced the baking time. I served with oven roasted baby potatoes and roasted asparagus. Yum!
Thank you Jenn!
Hey Jenn! Could this topping used on Mahi Mahi?
Thanks!
Rita
Yep 🙂
I will be making this dish for 40 people. Would it be okay to chop the herbs in a food processor rather than by hand?
And how many pounds of salmon filet would you estimate for 40 servings?
Thanks again for this wonderful recipe!
Marilyn
Hi Marilyn, Sure, you could use a food processor to chop the herbs. And for 40 servings, I’d recommend 11 – 12 pounds. Hope everyone enjoys! 🙂
Thanks! I was concerned with the herbs getting too mushy (technical term) in the food processor, but what a time saver!
Marilyn
This is an amazing recipe. It turned out perfectly. I didn’t change a thing but it needed a few more minutes to completely cook to the flake stage. The salsa was so good. You could make this topping for cold chicken too, I’m sure. What made this the ultimate company/dinner party dish is that you can make it ahead of time. I prepared the dish in the late morning and it was enjoyed cold.
OMG – this is the best, best, best salmon recipe I’ve ever had. Easy, light, healthy and delicious. If you love salmon you have to give this one a try. Jennifer is the BEST !!!!!
Absolutely delicious. Well worth seeking out all the fresh herbs for the salsa. I made it as an appetizer for a party of 35, doubled the recipe and not a morsel was left!
Thank you!
Oh.My.Dear.Lord. This is the first time I have slow roasted a salmon (Costco size which, was done in the prescribed 50 minutes;) and, it is absolutely succulent! I made this recipe for a potluck dinner tonight. This is the best salmon recipe I’ve tried by far. So good. So healthy. So fresh! I love the herb salsa. I love that I can make it ahead and not have to worry about it being cooked/heated to smithereens at the other end. Thank you, Jenn!
PS Not sure why the board won’t let me rate your recipe. I rate it 5 stars!!
I tried this low temperature cooking method with steelhead trout as well and the result was fabulous. I don’t think I will use any other temp from now on! Thanks!
We’re not big tarragon fans. Would fresh mint work well? Other suggestions?
Karen
Hi Karen, I would just leave it out. Enjoy! 🙂
I have never commented on a recipe, but this was SO good, I had to add my endorsement. Slow roasting was a revelation to me in terms of the creamy texture and the salsa was such a light touch, we all loved it, even my young kids. I served it with a garlic/olive oil couscous and a simple green salad. Thanks so much, Jenn!
Glad you enjoyed it – thanks for leaving a review! 🙂
Ah!
And I just looked at the leftovers, stil bright green!
The sauce, of course! Ha!
I want to bring this to an open house party with heavy appetizers. Would you suggest bread slices or crackers or something else to serve with it?
Hi Nancy, This dish really stands on its own, but I think a sliced baguette or rolls would be nice.
Outstanding! Another addition to my “cook-once-eat-twice” recipes! Particularly useful for the busy household where everyone doesn’t sit down to dinner at the same time (as in “Mom, I want to go work out before I eat dinner.”) Thanks again Jenn!
I used one of Costco’s giant salmon filets and it cooked perfectly with the instructions provided. It was marvelous, there wasn’t a morsel left. ( I have to admit the protein accumulated on the top is a little gross.) The salsa is delicious and makes a generous amount. I can’t wait to make it again.
I use a helpful hint that I once found on the internet. To prevent the white stuff oozing, use a salmon brine. 1 Tablespoon salt to 1 cup of water, for 10 minutes. After I do it, I sometimes give the salmon a quick rinse and then pat dry with paper towels, although I’m not sure that’s necessary.
Hi Jenn,
I am planning to make this recipe tomorrow. I have 4 (7oz) salmon filets in the freezer. Should I thaw them overnite in the fridge or can I slow roast them from the frozen state?
I have purchased your cookbook and want to say thanks for the many recipes from it that I have made. I have yet make a recipe that I did not rate as “fantastic!” Purchased a copy for my new DIL FOR Christmas; she was thrilled!
So happy you’re enjoying the cookbook, Marilyn! I would defrost the salmon overnight for best results. 🙂
Do you think the less oily Sockeye and Coho salmons would work? They tend to be thinner so cooking time would be less, but do you think they have enough oil content?
Hi Kate, This method does work best with fattier fish, but I think those would be fine.
My husband can’t have any vinegar except white distilled. Is there a substitute I could use for the white wine vinegar?
Hi Rachelle, Lemon juice would work beautifully.
Hey Jenn, I’m a parsley hater 🙊 but would love to try this. Do you suggest any other herb to sub? Or just omit the parsley?
Hi Erin, You could use more chervil, but that’s very similar to parsley so not sure how you feel about that. 🙂 Otherwise, you can just use more of the other herbs (although I wouldn’t add more tarragon as it’s strong in flavor).
FIVE STARS!! Made this for New Year’s Day and it was a big hit. It’s so versatile and can be used for more than holidays.
Moist & delicious. Made Asian inspired dressing w/soy & fish sauce, OJ & lime juice, rice wine, garlic & ginger w/a splash of sesame oiL + a touch of brown sugar.
I *love* salmon and have it a number of times a week. Coming from the (up there!) north of Sweden, I have a number of traditional dishes I make but salmon works so well with all kinds of cuisines.
Have never seen this slow roast way to cook salmon before. Very interesting!!
Can’t wait to try it out!
Hi Jenn,
Happy New Year and thank you for all your wonderful recipes! Silly question, what would happen if I let the shallots macerate in the vinegar for longer than 15 minutes? Looking forward to trying this dish as well…I’m sure it is amazing!
Hi Stacey, They will just be a little more pickled – it will be fine.
Love your recipes! Can the salsa be made ahead of time? The day before, even?
Hi Tara, Yes it keeps well for a day or two.
Hi Jenn, would the cook time be the same or adjusted if doing a smaller piece of salmon? Thanks!
Hi Cathy, You’d definitely need to reduce the cooking time for a smaller piece of salmon.
What do you think about doing this with frozen 6oz sockeye salmon pieces?
Hi Sue, I tried this with individual 6-oz portions and found they cooked much faster. It should work, just start checking after 20 min.
Thanks!
Hi Jen:
I see the salmon filet in your picture is not too thick –looks like 1″ max. If I have thicker filet will the slow roasting technique/temperature still work? If the filet is thicker and already pre-sliced to portion sizes, will the slow roasting technique/temperature still work? In either case, if technique is still sound, should I expect it to take more time to roast, and how much more?
As luck would have it, I have 7 lb of wild king salmon on order for our New Years Eve dinner!
Also, I do love your blog. It has been very helpful to me in making foods adventuresome enough to keep my 6-year-old kids’ palates expanding, but not so wild that they don’t try the food.
Thanks for the advice,
Kate
Hi Kate, Glad your family is enjoying the recipes! The technique will still work if the salmon is pre-sliced into portions, it will take significantly less time to cook. I’d start checking after 25 min. Hope you enjoy it!
Hello, I love your blog. It’s my favorite go-to for new recipes.
Do I just need more coffee this morning (rhetorical question) or have you omitted the oven temperature for roasting the salmon?
Hi TK, Ha! It’s 225°F – you’ll find it in the first line of the recipe, under “For the Salmon.”
I scrolled up and down several times, looking for the oven temp in the early section with the pictures. You would be doing us a favor if you added the 225 to the sentence that begins “Slide the pan into the oven, which has been preheated to 225 degrees…”
Done!
Hi Jen
I love your simple and descriptive recipes. What will be side dish with so flavorful roasted salmon.
Thanks
Poonam
Hi Poonam, It depends – will you be serving it for dinner, brunch, or lunch?
Suggestion for both please !
For brunch, this would pair really nicely with quiche or strata, fruit salad, and something sweet, like banana bread. For dinner, I’d serve it with steamed or grilled asparagus or haricots verts, and roasted or steamed baby potatoes. Hope that helps!
We’re definitely trying this recipe, Jenn never lets us down! I’ll be serving it simply with parsley new potatoes or small red potatoes and green beans!
Hmmm… where’s the reference to Samin Nosrat. This is copied verbatim from her book Salt, Fat, Acid, Heat.
Hi Travis, I mention her and her series in the first paragraph of the recipe. Hope you enjoy if you make the salmon!
