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

Do you cook salmon on high or low heat?

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.

Can you overcook salmon?

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.

Can you eat salmon skin?

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.

How do you know when salmon is finished?

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.

What temperature should Salmon be cooked at?

For slow roasted salmon, cook at 275˚F.

How do you keep salmon moist when baking?

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 (like Garlic Butter Noodles) 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!

    Made this for dinner, using wild caught sockeye fillets since there are just 2 of us.
    Really like the flavor of the slow roasting, really easy.

    1. Marissa Stevens says:

      I’m so glad you enjoyed this, Carmen!

  2. Mimi Rippee says:

    This is a wonderful recipe. I typically just pan-fry my salmon in browned butter. Fast and easy for me, since I’m the only one who eats salmon! But the slow-roasting is a fabulous idea, and the resulting dish is gorgeous.

    1. Marissa Stevens says:

      Thank you, Mimi! Your method sounds fantastic too.

  3. Laurel Stein says:

    Sounds amazing. Looking to cook ahead and serve cold. Would this recipe be appropriate?

    1. Marissa Stevens says:

      Hi there, Laurel. Yes, absolutely! We enjoy the cold leftovers on salad whenever we make this.
