These simple healthy salmon sweet potato fish cakes contain a little cream cheese and refreshing lemon zest. This minimalist recipe is super quick and easy to throw together especially if you prepare the ingredients ahead. You can either prepare the salmon specially or use salmon leftovers.

My healthy sweet potato fish cakes are very low in fat and contain super nutritious ingredients. In addition to the salmon they are made using sweet potato, as well as a small amount of cream cheese. The cheese helps to create a smooth and creamy texture and adds a bit of tangy flavour which offsets the sweetness of the potato.

You can use either regular or low fat cream cheese.

Preparing the salmon for salmon fish cakes

Unless you are using salmon leftovers start by baking the salmon together with the sweet potato. Place the salmon on top of a baking sheet lined with non-stick baking paper, season, drizzle with a little lemon/lime juice and add a knob of butter. Bake in the centre of the oven for about 15 minutes or until fully cooked, taking care not to overcook it. Remove from the oven and set aside to cool (leave the sweet potato in the oven as it will need more time to fully cook). Remove the skin (if present) before adding into the fish cakes mixture.

Can I use frozen fish to make sweet potato fish cakes

Yes, you can! Simply place your frozen fish in a pot, cover and simmer until fully cooked, stirring occasionally to prevent it sticking to the pot. You don’t need to add any water as the salmon will release lots of moisture as it defrosts. Drain off the water (do this thoroughly), allow the fish to cool and make the recipe.

I used salmon but either cod or haddock would also be good choices. Prepare from fresh or frozen.

Preparing the sweet potato for sweet potato salmon cakes

Bake the sweet potato along with the salmon (unless you are using already cooked leftover salmon).

Cut the sweet potato lengthways and place (cut side down) on a baking sheet lined with parchment paper. Bake on the top oven shelf (with the salmon underneath) for approx. 30 minutes or until fully cooked and tender. Once you’ve removed the salmon increase the heat to 200 C and finish baking the potatoes until tender.

Remove from the oven and leave to cool. Scoop out the pulp and add into the fish cakes mixture.

How to make salmon sweet potato cakes: step-by-step

1. Preheat the oven to 190 C. Cut the sweet potato lengthways and place, cut side down, on a baking sheet lined with parchment paper. Bake in the upper part of the oven for approx. 30 minutes or until fully cooked. (If you are preparing the salmon from raw, season, drizzle with a little lemon juice and oil and bake simultaneously in the centre of the oven for 15 minutes). Remove from the oven, scoop out the pulp and set aside to cool.

Top tips

Sweet potato: I recommend using small sweet potatoes as they will take less time to cook than large ones.
Make ahead: Both the salmon as well as the sweet potato can be cooked ahead and refrigerated (for up to 2 days) until you are ready to make the fish cakes. Make sure they have cooled completely before popping them in the fridge.
Using salmon leftovers: This healthy salmon cakes recipe is ideal for using salmon leftovers. Simply combine the fish with the rest of the ingredients and follow the instructions for making the fish cakes.
Frying: Do not overcrowd the pan so you can easily turn the fish cakes over. Fry briefly, for approx. 2 minutes on each side, until golden brown.
Best served immediately. Refrigerate leftover fish cakes in a closed container for up to 3 days.
How to freeze fish cakes: Place uncooked fish cakes in an airtight container and separate with parchment paper so they don’t stick to one another and freeze for up to 3 months. To defrost the fish cakes remove from the container and spread on top of a plate. Fry as per Instructions.
