Why We Love This Recipe

Low carb – These Keto Fish Cakes have only 1g net carbs.

Versatile ingredients – You can use any type of fish you have a preference for. You can make the recipe dairy-free by choosing substitutes detailed in the recipe notes.

No fillers – My recipe does not contain any of the traditional, non keto compliant, filler vegetables. If you wanted to make a more budget conscious version, you could add some mashed cauliflower to make the ingredients stretch a further.

Quick and easy – There is very little active preparation and cooking time involved, and the steps are quick and simple!

Thermal-cooker friendly – This is an easy recipe and I have included instructions for making the fish cakes with a Thermomix and a Magimix as well.

Keep reading for more details on the ingredients, substitutes and step by step instructions on how to make them.

The Ingredients

Keto fish cake ingredients measured out in individual bowls.

Fish – I recommend using firm, white fish for this recipe. I chose skinned and deboned fresh flathead fillets. You could easily substitute salmon or any fish you prefer.

Herbs and spices – Fresh parsley and keto pantry spices are all you need to make these fish cakes.

Lemon zest – Lemon and fish are made for each other, and just a pinch of fresh lemon zest gives the fish cakes a delicate, complementary flavour. If you don’t have a zester, there are other ways that don’t include having to buy a new kitchen utensil.

Easy Keto Mayonnaise – This takes a few minutes to whip up using my fast and easy recipe, if you don’t already have some stored in your fridge.

Egg wash – My recipe uses just egg and a little Dijon mustard, or any mild mustard. Cream or milk is not needed!

Crumb – I choose to use pork rind crumbs and finely grated parmesan. You can substitute the pork rinds with golden flax meal. Almond meal or chia flour both work well as a coating for these fish cakes. The parmesan can be substituted with nutritional yeast flakes for a dairy-free version. They can also be left completely uncoated if preferred.

Step by Step How to Make

Step 1: Add all the fish patty ingredients to a thermal mixer bowl or food processor. Pulse until the mixture comes together and shape into four large patties. TIP: Using a large egg ring or a hamburger press makes the patties more uniform in size and thickness. Place the patties on a plate in the freezer for 30 minutes to help with the crumbing.

Step 2: Preheat the oven to 200°C/390°F. Line a baking tray with baking paper and set aside until needed.

Step 3: Combine the crumb ingredients in a small bowl. Whisk the egg wash ingredients in a separate small bowl. Coat the chilled fish patties in the egg each before rolling gently in the crumb mixture.

Step 4: Bake in the preheated oven for 15-20 minutes until golden and cooked through.

Step 5: Once baked, fry in a hot frypan for 1 minute on each side to brown the coating. TIP: This step is optional, but recommended to enhance the look and texture of the coating.

Hot Tips & FAQs

Can Keto Fish Cakes be made ahead?

Yes, you can prepare the fish cakes and either cook them later that day when needed or keep them frozen for up to 1 month.

Where do I get Pork Rinds or Golden Flax Meal from?

Health Food and Keto or Low Carb stores would carry Pork Rinds and golden flax meal. I buy and use Porking Good Pork Rinds. If you are unable to get golden flax meal or have a sensitivity to flax, it can easily be substituted for an equal quantity of almond meal.

Are there other ways to cook the Fish Cakes?

Yes, there are quite a few other ways to cook them!
1. Fry or airfry without baking.
2. Steam the uncoated fish patties over a double boiler for 15 minutes or until cooked through.
3. Wrap the uncoated fish patties in yuba skins before steaming them as above. They can then also be fried for a crispy coating.
4. Steam uncoated fish cakes in a Thermomix. Add 500ml of water to the mixing bowl. Place the fish patties in the top, shallow tray of the steamer. Assemble the steamer and steam for 15 minutes/120°/speed 2.

How can I make this recipe in a Magimix?

Use the food processor attachment of your Magimix and pulse the fish patty ingredients together. Continue by following the steps in the conventional method or steam as above

Notes

Fish: I recommend using skinned, deboned, firm, white fish for this recipe. You could easily substitute salmon or any fish you prefer. Prawns / shrimp would make a tasty variation as well!
Dairy-Free: Simply substitute the parmesan in the crumb with nutritional yeast flakes.
Pork Rinds – I use Porking Good Pork Rinds, but please use your favourite brand.
Golden Flax Meal: Golden flax meal is usually available in health food stores. If you are unable to get some or have a sensitivity to flax, it can easily be substituted for an equal quantity of almond meal.
Alternative coating – You can also wrap the fish cakes in chicken skins or crepinette (caul fat) and fry for a super-crunchy coating. Almond meal can also be used in place of golden flax meal.
Alternative Conventional Cooking Methods:
  1. Fry or airfry without baking.
  2. Steam the uncoated fish patties over a double boiler for 15 minutes or until cooked through.
  3. Wrap the uncoated fish patties in yuba skins before steaming them as above. They can then also be fried for a crispy coating.
Alternative Thermal Cooker Method:
Steam uncoated fish cakes in a Thermomix / Thermal Cooker.
  1. Add 500ml of water to the mixing bowl.
  2. Place the fish patties in the top, shallow tray of the Varoma.
  3. Assemble the Varoma and steam for 15 minutes/Varoma/Speed 2.
Serving Suggestions: Keto Fish Cakes are great on their own with some seasoning, and lemon or lime wedges. For a more substantial meal, add a simple salad and a serve of my Keto Tartare Sauce.
