PIN Slow Cooked Salmon to try it later!

For years I’ve seen those large pieces of fresh salmon from Costco and haven’t tried cooking a large fillet of salmon, partly because there were already so many excellent salmon recipes on the blog. But when my niece (and fantastic cooking assistant) Kara raved about a salmon recipe she spotted in a very old Instagram post, we decided we had to try it. And this Slow Cooked Salmon with Butter, Garlic, Capers, and Lemon was absolutely amazing!

I’m calling this slow cooked salmon because the salmon is cooked in the oven at a low temperature for 30 minutes, first wrapped loosely inside foil and then unwrapped to finish cooking. Before it’s wrapped the salmon is seasoned with my favorite Szeged Fish Rub, then drizzled with melted butter that’s combined with minced garlic and capers, and it’s finished with fresh-squeezed lemon juice.

I’ve never cooked salmon at a low temperature for a long time before now, but this salmon was so moist and flavorful that I know I’ll be making this again when I want an idea for a special dinner! And this recipe is absolutely perfect when you’re making a special dinner for guests and want something that’s completely a wow!

What ingredients do you need?

• large fresh salmon fillet
• Szeged Fish Rub (affiliate link)
• butter
• minced fresh garlic or Minced Garlic (affiliate link) will work if you prefer it
• Capers (affiliate link)
• fresh-squeezed lemon juice
• fresh chopped parsley, optional
• salt and fresh-ground black pepper to taste

Can you use skin-on salmon for the Slow Cooked Salmon?

We used a two pound fillet of skinless salmon for this recipe. But if you prefer salmon sold with the skin on, that will still be great.

Can you make this recipe with smaller pieces of salmon?

You could definitely make this recipe with a smaller salmon fillet, or even with individual pieces of salmon, just adjusting the amount of butter, garlic, capers, and lemon. I do think smaller pieces might cook a bit more quickly so I would start checking after about 24 minutes cooking time.

Do you have to use fresh garlic?

We used fresh garlic cloves that we minced with my favorite garlic press (affiliate link), but if you don’t mind having a slightly milder garlic flavor I think minced garlic from a jar will work for the recipe.

Does Slow Cooked Salmon keep in the fridge?

There is absolutely no doubt that this slow cooked salmon will be most flavorful when it’s freshly made. But I did reheat some leftover salmon quickly in the microwave (or use a hot pan on the stove) and it was still quite tasty, especially with more lemon squeezed over the salmon. I ate my leftover salmon the next day, and I don’t think it will stay good much longer than that.

1. We used a two pound skinless salmon fillet.
2. Rub the salmon with Szeged Fish Rub (affiliate link) and let it come to room temperature while you preheat oven.
3. Use a garlic press (affiliate link) to mince 1-2 T of minced garlic.

6. Add minced garlic to the melted butter and cook 1-2 minutes on low.

10. Put sheet pan in the oven and bake 15 minutes.
11. Remove sheet pan from oven and open the foil, moving it away from the salmon.
12. Put salmon back into oven and bake 15 minutes longer.
13. Chop fresh parsley and cut some pieces of lemon while the salmon continues to bake.
14. After 30 minutes, remove salmon from the oven, sprinkle with parsley, season with salt and fresh-ground black pepper to taste, and serve with lemon if desired.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Slow Cooked Salmon is a perfect dish for any low-carb or Keto diet. Salmon cooked in butter would be high in fat for the original South Beach Diet but you could probably make a pretty good-tasting result even using less butter if you prefer.
