These Keto Fish Cakes with Roasted Red Pepper Salsa are perfect for summer or anytime you have a craving for fresh fish! Healthy fish in a kid friendly package that the entire family will enjoy!

When I was a kid and hated fresh fish, the only way I could stand it was in a fish cake. If there was enough seasoning to mask the fish flavor, and enough breading to make the texture unrecognizable, then I was tentatively on board. If it had a delicious sauce that I could slather it with, even better.
As an adult, I now love fish in all it’s forms. These days, if my fish is served in cake form I want as little breading involved as possible – in fact these keto fish cakes have no breading or nut flour fillers at all!
I’m still a fan of lots of bold flavor in my fish cakes, but now I’m looking to complement the fish, not mask it entirely. I still love a tangy, fresh sauce or salsa to slather on it though.
These easy keto fish cakes are a winner on all counts!

These keto fish cakes are great on their own, but that roasted red pepper salsa is so perfect with them that I highly recommend it! You can buy roasted peppers in a jar or can, but if you have a gas stove or grill and a few minutes to spare, you can make your own and it’s SO. MUCH. BETTER.


Simply roast the peppers over the open flame until charred, then place in a plastic or paper bag, or a bowl with plastic wrap over the top. Let them cool for 10 minutes, then remove them and the skins will slip right off. Slice and remove seeds and you’re ready to use them. They can be frozen for up to 6 months and you’ll have them handy whenever you need them!
I used snapper for my keto fish cakes, because it’s widely available here in Honduras. Any firm white fish that you have access to in your area will work just as well!
I’d like to think that if I’d had access to these keto fish cakes with roasted red pepper salsa as a kid, my appreciation for fish in all its forms would have begun at a much younger age. Give these a try with your tribe and see if it wins them over – then be sure to report back!
NOTE: People seem to be having trouble with these fish cakes falling apart for some reason, and I’m not sure if it’s the type of fish, using more than the 1 pound called for, or if people don’t know what a 1/2 inch dice is and are cutting the pieces too large. The mayonnaise and parmesan should form a glue that keeps the fish held together, and while you do need to be fairly gentle with them when turning, they shouldn’t be falling apart. I’m going to adjust the recipe and add some coconut flour and an egg, though I personally feel the recipe is better without it. If you’re reading this first and are a confident cook, then I recommend trying this recipe without the coconut and egg first, being sure to press your cakes tightly together before cooking.

Christine Colmer says
I made these fishcakes for the first time this week. I was amazed at how tasty they were! I think next time (soon!) I will cut the fish into smaller chunks.
I found the salsa sauce a bit too bland so I added some extra seasoning.. otherwise absolutely scrumptious! Thanks for this!

Bake this today. Only used the cheese no eggs or coconut flour.They need to be in the refridgerater for at least 4 hours before baking. This is really importend. Simple Delicious. Thanks so much for this recipe! I wrap the balls in cling wrap before refridgerated and rolled them in parmesan before frying on low heat so the cheese can melt before turning them.
