Any tips for making this keto fish fry recipe a success?

  • Hot oil up to temp, otherwise batter will fall off.
  • Don’t overcrowd the pan since temp will drop and the batter coating won’t crisp up.
  • Try not to let the batter sit for too long, otherwise, it will start clumping and getting thick due to the almond flour.
  • If you want, re-fry to make the outside extra crispy.

  1. I did the recipe exactly, however the batter did not stay on the fish and my pan and oil where Hot!!! ?

    • LowCarbingAsian

      Hi Maggie – sorry to hear that. Was the batter thick when you made it? If not, there is a chance too much carbonated water or too little almond flour was used.

  2. Best coating ever, I didn’t have sparkling water but I did have an ice cold Mic Ultra that was the perfect substitute! Thanks for sharing my new go to breading,

    • LowCarbingAsian

      Hey Deb! Great to hear you liked the fish batter! Yup, a Mic Ultra will do just fine as well.

  3. I had the same problem with the batter not sticking. I followed the directions because I wasn’t sure with the almond flour how it would turn out, but in normal bartering, you want to go wet-dry-wet. So typically you would coat your fish (wet) in flour (dry) and then dip in the batter. Dipping wet fish (even if it’s patted dry) into wet batter will only result in slide offs unfortunately. Next time I’ll try dipping the fish in either some extra parm or almond flour first.

    The taste of what did stick was great, and I modified the sauce by adding some extra lemon juice and some old bay and garlic powder, and it made a great remoulade type sauce to dip it in.

    • LowCarbingAsian

      Hey Adam – The only thing I can think of is the fish fillets might have not been thoroughly dried or the batter was too watery. You can try to add some flour before the batter, but if the fish fillets are properly dried, the the flour probably won’t stay on the fillet.

      Update – Hey Adam, after getting your comment, we decided to we test this recipe and we found out adding another egg to the batter really helps bind the batter in place once it hits the oil. So if you decide to give this recipe another go, please give that a try!

  4. Sharon Barlow

    Made this for dinner tonight and it was so good. I did add 1 tsp more almond flour and patted the fish really dry, the batter stayed on perfectly. I also added a drop of mustard to the tarter sauce but it is a keeper.

  5. hi, can i ask what type of frying oil you guys use?

    • LowCarbingAsian

      Hi Toby! We use regular ol’ vegetable oil but you can use whatever your preferred frying oil is. Just make sure the oil is up to temp otherwise it will become a soggy mess (personal experience)!
