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.
