Once I discovered that Slow Roasted Salmon always comes out buttery and meltingly tender, I've never looked back. Dinner party elegant, but easy enough for a weeknight it never disappoints.
Brushed with olive oil and seasoned simply with salt and pepper, the salmon fillet cooks low and slow. This recipe has you drizzle the cooked salmon with a silky lemon butter sauce with capers and finish with a shower of fresh chives and parsley. But that's just one of endless options. Take the finishing touch in any direction that compliments the rest of your meal (suggestions below).

Ingredients You Need to Make Slow Roasted Salmon
- Salmon: Ideally a wild salmon fillet of uniform thickness. A tail cut works just fine, but the thinner areas will cook more than the thickest parts. Salmon varieties to look for: King Salmon (also called Chinook Salmon), Coho Salmon, or Sockeye Salmon.
- Olive Oil: Your favorite extra-virgin variety.
- Kosher Salt and Freshly Ground Black Pepper
- Butter: Salted or unsalted butter - whatever you have on hand.
- Capers: Ideally tiny, firm, flavorful non-pareil capers, rinsed and drained.
- Lemon: You'll need one lemon to juice for the sauce and a second if you'd like to serve your salmon with lemon wedges.
- Chives: Look for perky, deep green chives.
- Parsley: Fresh flat leaf or curly parsley - use the variety you like best.
Salmon Cooking FAQ
You can cook salmon on high or low heat, depending on the texture you're looking for. You'll find recipes as low as 200˚F and as high as 500˚, or broiled salmon that, on full broil, cooks at 550˚F.
Cooking salmon can be tricky because It's so easy to overcook, particularly when you are cooking it at a high temperature. And, like other meats, it will continue to cook from residual heat once you remove it from the heat source (oven, grill, or stovetop), so it's important to remove it before it reaches your target temperature.
Yes, you can eat salmon skin, but it's best when crispy. This is easiest with pan seared salmon. With slow roasted salmon, you could crisp the skin in a skillet at the end of cooking, but you run the risk of overcooking the flesh.
You'll know your salmon is finished cooking when the tip of a knife meets no resistance and the flesh is slightly opaque (it will be less opaque / milky white with slow roasted salmon than salmon cooked at higher temperatures). For internal temperature, the FDA recommends 145˚F, but many chefs recommend 125˚F.
For slow roasted salmon, cook at 275˚F.
Slow roasting salmon is the best way to keep it moist when baking!
Recipe Options:
Feel free to experiment with different sauces and aromatics to finish your salmon. Here are some suggestions:
- Prepare this salmon recipe, but add minced fresh garlic cloves instead of capers to the lemon butter mixture and finish with fresh dill or a variety of fresh herbs and lemon zest. Or drizzle with my Lemon Garlic Butter Sauce.
- Top cooked salmon with a Mango Avocado Salsa or Pico de Gallo.
- Drizzle with a mixture of soy sauce, toasted sesame oil, and a touch of honey. Finish with a shower of sesame seeds and thinly sliced green onion.
What To Do with Leftovers
If you're fortunate and end up with leftover salmon, it's wonderful the next day served cold on a salad or broken up and tossed with pasta and sautéed vegetables for an easy meal. Or do what we usually do and make these fabulous Fish Cakes - typically made with leftover cooked cod or halibut, but salmon works great too!
What to Serve Alongside
- Arugula Salad (Just 6 simple ingredients in this salad that everyone loves.)
- Sugar Snap Pea Salad (When sugar snap peas are at their spring peak, this is the way to go.)
- Lemon Garlic Asparagus (The perfect balance of rich and bright, this is a 10 minute side dish that you'll learn to make by heart.)
- Strawberry Spinach Salad (We enjoy this on repeat when strawberries are in season.)
- Creamy Cucumber Salad (This would be particularly good with the dill topped recipe option above!)

Sounds amazing. Looking to cook ahead and serve cold. Would this recipe be appropriate?
Hi there, Laurel. Yes, absolutely! We enjoy the cold leftovers on salad whenever we make this.
Made this with King Salmon, the arugula salad mentioned, pesto pasta and french bread. Really good. I so very much wanted to add garlic to the butter sauce but made as instructed and likely won't mess with garlic next time either. My only note is personally I was very liberal with the parsley/chive combo.
So glad you enjoyed this, Yukon! Thank you for your cooking notes too.
Marissa, 10 stars for this absolutely tender and delicious dish! Flaky fish, perfectly slow cooked. I used a thermometer to get the perfect temp. The sauce is light, so flavorful and just perfect on the fish. I now have my favorite way to make salmon! Amazing!
Aww...Beth, you made my day. So glad this was a hit!
Marissa, this is a beautiful salmon dish. I've been making a lot of salmon lately, as I especially love it in the summertime. I've poached it slowly, but never roasted it this way. I must try it! And that caper sauce -- yum! 🙂 ~Valentina
I bet poaching it slowly is delicious too! We poach chicken all the time, but I never think to poach fish. Thank you, Valentina!
I love the look of this texture, Marissa! You are so right, it's so easy to overcook salmon and then you end up with something quite dry and unappetising. I am in love with the sound of this butter too, yum! What a perfect weeknight dinner.
Thank you, Katerina! I love when something this good is easy enough for a weeknight!
It's been a while since I slow roasted salmon. Your photos have me drooling and wondering why I don't make it more often! Obviously I have seen the error of my ways and I'll be preparing your beautiful salmon recipe PRONTO! You knocked this out of the park - it looks truly perfect!! Pinned!
aww...thanks so much, Cheyanne! xo
What a cool idea! Whenever we make salmon, we typically either grill it or bake it. The idea of roasting salmon at a lower temperature is intriguing. I totally have to try this out now! Looks like a delicious recipe, Marissa!
Thank you, David. I hope you'll give this a try!
Did you know that just last night I had to toss a beautiful piece of salmon!? So sad. I thawed it overnight in the fridge, but when I went to cook it, it had a bit of a slime to it. I didn't want to risk it! Anyway, salmon is one of my fave things to eat, so now I definitely have to try this slow roasted technique of yours!
Oh no...that's such a crummy feeling. Hope you'll give this method a try!
I've never cooked salmon low and slow like that but, from your pics, it looks like I need to try! Looks incredibly tasty, Marissa, and just perfect for date night at home with a glass of vino 🙂
Being the fish love that I know you are, I think you'll love it, Dawn!
Totally looks melt in your mouth tender Marissa! My husband Tom would love the lemon and capers. Nice and light, so it's the perfect summer dish. Can't wait to try it!
Yay! I hope that you and Tom love it, Mary Ann!
The salmon did turn out really tender and juicy. I too like to slow roast the salmon once in a while..my favourite is still pan sear them until CRISP..because the skin is the BEST part :-))
That crispy skin is pretty delicious!
