Why You’ll Love It

The first time I made these fish cakes I don’t think they lasted more than 10 minutes in my house. My kids jumped in and ate everything almost immediately and begged me for more.

These keto fish cakes are seriously addicting and so filling. When I make a batch, I eat 2 or 3 and I’m too full to eat anything else for hours. And I usually have to make more than one batch at a time because everyone in my house loves it.

Ingredients Used

  • Codfish: I use codfish but you can use any other white, flaky fish like tilapia, catfish, or grouper.
  • Eggs: This acts as a binder so that the cake can hold its form and not fall apart immediately.
  • Coconut flour: This makes the fish cakes even more filling and helps to absorb excess moisture when preparing the fish cakes.
  • Vegetables and herbs: I use parsley for this recipe but you can use any of your favorite herbs. I also add some chopped onions for a burst of flavor.
  • Spices: I use black pepper, cayenne pepper, smoked paprika, and salt for this recipe. You can always use your favorite spices.

How to Make Keto Fish Cakes

  1. Wash and pat dry the codfish. You don’t want it to be soaking wet or dripping with water or it will become soggy and not hold its shape.
  2. Spray a pan with a little oil, and rub the fish with salt and pepper. Fry on one side for about 5 minutes, then flip and fry the other side.
  3. When the codfish is done, take it out of the pan and give it about a minute to cool. Then use a fork to flake it into smaller pieces. It does not have to be perfect because we will still use an immersion blender to blend and mix everything.
  4. Add in the chopped onions, parsley, coconut flour, eggs, and spices. Mix together and use an immersion blender to blend everything together. It does not have to be smooth; a coarser texture is actually preferred. I found out through trial and error that the fish hold its shape better when coarsely blended especially since it contains onions.
  5. Use a quarter measuring cup to scoop out the fish and press in to compress it. Flip it on a plate and gently pat down to shape it. This should give around 6 to 8 fish cakes dependent on how large or small you make them.
  6. Add 2 tablespoons of olive oil to a frying pan and place the fish in it. Let it fry for about three minutes on each side on low to medium heat. Gently flip the fish cakes over using a spatula. As the outer edges begin to brown nicely on both sides you know your fish is ready.
  7. Don’t panic if you see the top and bottom begin to turn dark brown. It is not getting burned, this is supposed to happen. This shows that the fish cakes have cooked through.
  8. Serve and enjoy!

What Can I Eat My Keto Fish Cakes With?

I love to eat this with spicy mayonnaise or top it up with this spicy avocado salsa for an amazing flavor combination.

You can also serve it with a low-carb salad for a delicious lunch and add different herbs and spices to mix things up!

Tips and Variations

  • Make sure the fish is not too soggy. If you end up with too much water in your fish and it is not holding its shape, add a little bit more coconut flour. Coconut flour absorbs moisture so it will help absorb the excess moisture from the fish.
  • If it is too dry, sprinkle just a little water on it. You want it to be just moist enough, not too wet or too dry.
  • If your fish cakes are breaking apart when frying, it could be for a couple of reasons. The oil might be too hot. I have noticed that when this happens, the fish breaks apart or burns very easily.
  • Another reason might be the quantity of oil used. If you use a lot of oil, the fish cakes tend to just break apart and float away. I have achieved the best results when I use just a tiny bit of oil on low heat, to give the fish cakes time to cook through without breaking apart or getting burned.
  • Be careful when trying to flip the keto fish cakes when making it. Use a flat spatula and flip it gently.
  • It is also important to give the fish cakes a few minutes to cool down before you eat them. This would give them time to solidify and reduce the chance of breakage.
