Keto salmon with pesto and spinach

How much do you love both pesto and salmon? If the answer is “more than pretty much anything in the world,” then this is the recipe for you! Bonus: It’s fast, keto, and gorgeous. What more can you want?
4 servingservings


  • 1½ lbs 650 g salmon
  • 1 cup 225 ml mayonnaise or sour cream
  • 1 tbsp 1 tbsp green pesto or red pesto
  • 2½ oz. 75 g parmesan cheese, grated
  • 1 lb 450 g fresh spinach
  • 1 oz. 30 g butter or olive oil
  • salt and pepper


Instructions are for 4 servings. Please modify as needed.

  1. Preheat the oven to 400°F (200°C).
  2. Grease a baking dish with half of the butter or oil. Salt and pepper the salmon fillets and place them in the prepared baking dish, skin-side down.
  3. Mix mayonnaise, pesto and parmesan cheese and spread over the salmon.
  4. Bake for 15–20 minutes, or until the salmon is done and flakes easily with a fork.
  5. Meanwhile, sauté the spinach in remaining butter or oil until it’s wilted, about 2 minutes. Season with salt and pepper.
  6. Serve immediately with the oven-baked salmon.


Dairy free? No problem! For a dairy-free dish, skip the parmesan and sour cream, and fry the spinach in olive oil instead of butter. Also, remember that green pesto usually contains parmesan, so reach for some red pesto instead.

    Before eating healthy salmon.

    I used mayonnaise option and found it too "clawing" tasting. There is a very similar recipe on here which has the topping as mayo, pesto & yogurt which I had last week which was much nicer.

    Just made this tonight and it was absolutely delicious. It actually serves about 6 people. The sauce on top makes this dish. I did add a few red pepper flakes to the spinach. Oh, and I used Primal Kitchen's avocado mayonaise instead of sour cream. I'm not sure what Jane found "clawing." My entire family raved about it. Thanks for all you do, Andreas, to give us such great recipes!

    I made a half recipe (actually half a small wild pink salmon ) for my husband and myself. Used high fat 'Balkan style' yogurt (6%) and home -made pesto. Baked it surrounded by chunks of partly cooked sweet potato and white turnip and served with kale stir-fried with red sweet pepper and onion. Really yummy.

    All the supermarket pestos are made with seed oils. Can anyone recommend a brand available in Australia not containing seed oils?

    The pesto sauce works nicely when made with 50-50 Mayonnaise and sour cream although I always try to go light on the Parmesan. For an additional side, crispy sautéed brown mushrooms are always well received. I find the Spinach benefits from a little garlic. Alternatively, sautéed mushrooms and watercress work well for when you get fed up with spinach.

    it would be great if we knew the macros

    i changed the mayo to sour cream and its was truly delicious

    To be honest, while the recipe was okay, I honestly enjoy a chef-tier pan-seared salmon in butter with simple seasonings a lot better.
  11. Suzanne
    I made it for my husband’s birthday dinner. Loved it. Served it on a bed of cauliflower broccoli rice. Made extra sauce. Added a lot more pesto. Very tasty then.
  12. Susie
    Try making your own. For this dish I just chopped some basil leaves with a pinch of salt and a clove of garlic.
  13. Susie
    As much as I love mayo, I couldn’t get close to eating 60 ml as suggested in this recipe!
  14. Thomas
    I replaced the mayonnaise with crème fraiche and it was just delicious. Easy and fast to prepare and makes you feel quite full!

    900 calories? I doubt that, but it would be nice to trust the nutrition info of these recipes. Some are really confusing.
  16. Yawa McDonnell
    Love this! Just made it and it is delicious, first recipe l’ve made from this website.

    This was fab.
    Great to portion up for work lunches.

    Delish! Perhaps a little too rich as I used mayo. Next time I would dilute it with yoghourt/sour cream. I worked out the calories and it came to 804 per serving and I used 125g less salmon, so the calorie count is correct.
  19. Rozzele
    First recipe used of this page. Really enjoyed it. I used less Mayo, and not all the sauce (it was so good I wish I'd used more) tracked in my fitness pal 700kcal so pretty accurate nutrition.

    One of the best DD recipes. Simple, quick and delicious!
  21. Marcin
    I love salmon, I love cheese, so this dish was perfect for me. I recommend adding garlic to the spinach for those who like garlic.
  22. Annalina
    I halfed the pesto sauce and used 50/50 mayo and sour cream, because I don't like overpowering mayo taste, and it was heaven!
    I added a spoonful of cream and grated cheese to the spinach as well. SO yummy!

    Tzaziki can subsitute mayo if you're okay with a bit more sour like sour cream. 1 tablespoon is just 25 calories.
