What You Need To Make Salmon with Lemon-Herb Butter Sauce

  • Large skillet – I LOVE this non-stick skillet with a lid. Makes cooking so much easier!
  • Whisk – if you’re using a non-stick skillet, you’ll need a silicone whisk. This is my pick.
  • Sharp knife – Henckels are my knives of choice. Great value and quality!
  • Cutting board – use a dishwasher safe cutting board for easy cleanup

Ingredients to Make This Easy Keto Salmon Recipe

  • Salmon – start with fresh, wild-caught salmon if you can get it. De-boned will make your life easy!
  • Butter – use a good quality salted butter
  • Herbs – I kept it simple with parsley. See Chef Jenn’s Tips below for other herb suggestions
  • Chicken stock
  • Heavy whipping cream
  • Garlic
  • Lemon juice – fresh is best!
  • Cooking oil
  • Pink Himalayan salt and pepper

How To Make Keto Salmon with Lemon-Herb Butter Sauce

  1. Add the oil to the skillet and preheat it over medium high heat. Season and cook the salmon 2-3 minutes per side or until just cooked through. Set side.
  2. Mince the garlic and add it to the skillet. Cook through for 1 minute or until aromatic.
  3. Turn off the heat and add the chicken stock to the pan. Reduce the chicken stock by about half, then add the heavy whipping cream.
  4. Keeping the heat off, add the butter one chunk at a time, swirling it in with the whisk. When the chunk has melted, add the next.
  5. This should create a lovely and velvety sauce. Add the herbs and spoon over the salmon.

Chef Jenn’s Tips

  • Change up the herbs! Fresh herbs are best – try chives, basil, thyme, oregano. Rosemary is too strong for this dish.
  • Buy de-boned salmon, otherwise you’ll need a pair of tweezers to pull out all the pin bones.
  • Skin-on salmon is fine – it helps the salmon stay moist, but get your salmon de-scaled.
  • Don’t overcook your salmon! If you see white solids forming on the outside of your salmon, you’re cooking it too at too high a temperature. Salmon is best when it is just barely medium, about 130-F but the recommended internal cooking temperature for all fish is 145-F. I like mine at 130-F.
  • When making the sauce, don’t turn the heat back on! This is an emulsion sauce, meaning the butter is whisked into the other liquids to create a cohesive sauce. Too much heat will cause the sauce to break and the butter to separate.

What To Serve With This Keto Salmon with Lemon-Herb Butter Sauce Recipe

You can pair this tasty keto seafood recipe with any number of side dishes, but some of my favorites include simple roasted vegetables or a great salad topped with a creamy dressing.

Is This Keto Seafood Dish Freezer Friendly?

Not really, no. The sauce will break (separate into a buttery mess), and salmon tends to dry out in the freezer unless it is smothered in liquid like in a soup or in a casserole.

Is salmon keto?

Yes, totally! Salmon is a great source of protein and healthy fats, making it a GREAT choice on a keto diet.

How do you cook salmon without it drying out?

Salmon, especially if it comes to room temperature before cooking, cooks in minutes. Keep the heat at medium-high and start skin side up and cook it in a pan for 3-4 minutes depending on the thickness. Turn it over and cook an additional 2-3 minutes for a medium salmon.

What sauce goes best with salmon?

Salmon and lemon are best friends – the flavors really compliment each other!
