Growing up as a pescatarian I only wish I had eaten king fish every day. King fish is such a beautiful tasting firm fish that teams well with a few spices and a tasty fresh lemon Gremolata. Eaten raw, cured, baked or fried king fish is popular in many cuisines.

Following a ketogenic diet I think makes for easier meal prep times.

Seeing we are using more unprocessed foods and keeping our diet low carb, throwing a few ingredients together in easy keto meals is the best way to eat.

Making this dish is so easy and quick. Just follow the basic steps below and your meal will be done in minutes.

Keeps for a few days – make it ahead and serve cold in salads or low carb lunches.

Variations – make Whole30 mayonnaisepaleo, and keto-friendly fish with just a few ingredients.

The Ingredients

Scroll to the recipe card at the bottom for the quantity of ingredients used and the full detailed method to make salt and pepper fish.

Fish: I use kingfish. It is a meaty white fish that holds up well to frying or baking.

Whey Protein Isolate: I use this to help give a light crispy coating to the fish. You can use a non-bitter tasting aluminium free baking powder in its place (just use 1 tablespoon).

How to Make It

  1. Cut the fish into smallish pieces. Not too small as you want the fish to maintain moisture.
  2. Mix seasonings together and season the fish.
  3. Heat the oil over medium-high heat and fry seasoned king fish in batches for 2-3 minutes each side.
  4. Drain on paper towel and serve with favourite side and salad.

What to Serve with Fish

Personally, I am always happy to eat fish straight off the barbecue, pan or grill. I love it as it is plain and fresh, seasoned, fried, grilled, or in curries and fresh soups.

For this salt and pepper fish, I really wanted something a bit punchy so kind of ended up teaming it with a Lemon Gremolata. A gremolata is so easy to make and with great fresh ingredients.

Fish teams well with a light salad, a creamy dressing like homemade keto mayonnaise or keto ranch dressing.

  • Chop fish fillets into large chunks.
  • Mix all dry seasoning ingredients together.
  • Heat 2-3 tablespoons of olive oil in a frypan over medium-high heat.
  • Toss fish pieces in seasoning and transfer to frypan. Be careful to not over-crowd your pan and work in batches if need be.
  • Fry 2-3 minutes each side or until cooked through. Drain on paper towel.
  • Season fish well and serve with arugula salad, lemon and Lemon Gremolata.


I prefer to use Isopure Whey Protein Isolate.
Season fish only just before frying, do not do this ahead of time.
Salt and Pepper King Fish can be enjoyed as a hot or cold meal.

    This is the best fish coating I’ve ever used. It is amazing. Does not come off the fish when you cook it. Use any fish and it’s brilliant. Thankyou Megan

      You are very welcome Gael. So good to hear you enjoy it xx

    Hi, you can purchase farmed and wild caught barramundi. It’s a tropical species from northern Australia. Flesh is very soft. Hope this helps.

    1. Megan Mad Creations Hub

      That is awesome. Thanks for the recommendation.

  3. Suzette

    Thanks Megan! What is barramundi exactly? I’ve seen it but have never purchased it because I’m not sure if it’s a wild fish or farm-raised. Can you enlighten me please?

  4. Suzette

    Hi Megan,

    If I can’t find king fish, what would be a good substitute?

    1. Megan

      Any white fish Suzette, barramundi, snapper, mahi mahi, monk

    Delicious and sooo yummy, this looks like such a tasty dish!

  6. Brewster

    is there a sub for whey powder?
    So you don’t need an egg to make the season stick?
    Cheers, Brewster.

    1. Megan

      Whey makes a carb free coating that is light and crisp, you can sub almond meal if you wish. You dont need egg at all to make whey stick
