Making low carb simple



  1. Preheat the oven to 400°F (200°C). Grease a baking dish with half of the butter, or olive oil.

  2. Place the salmon fillets in the baking dish, skin-side down, and season them with salt and pepper.

  3. Pesto Topping

  4. In a small bowl, mix together the mayonnaise, pesto, and parmesan cheese. Spread it over the salmon.

  5. Place on the middle rack and depending upon the thickness of the filet, bake for 20 - 30 minutes. The salmon is done when it flakes easily with a fork.

  6. Meanwhile, heat the remaining butter or olive oil in a large pan, over medium heat. Saute the spinach for about 2 minutes, or until the spinach is wilted. Season with salt and pepper, to taste.

  7. Plate the spinach with the baked salmon, and enjoy!

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.

    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.

    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.

    Try making your own. For this dish I just chopped some basil leaves with a pinch of salt and a clove of garlic.

    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.

    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.

    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.
