You've probably been there. You have some leftover cod or a couple of tins of salmon, and you think, "I'll just whip up some fish cakes." Then, ten minutes later, you're staring at a pan full of greasy, structural failure. It’s frustrating. Honestly, figuring out how do i make fish cakes that actually hold their shape while staying light and fluffy is a rite of passage for any home cook. Most people mess this up because they treat the fish cake like a burger or a crab cake. It isn't. It’s a delicate balance of moisture control and temperature management.
If your cakes are mushy, you used too much binder. If they're dry, you overcooked the fish before it even hit the pan. Real fish cakes—the kind you get in a proper coastal tavern—rely on the starch of the potato to do the heavy lifting, not just a handful of flour.
Why Your Fish Cakes Keep Disintegrating
Structure is everything. Most beginner recipes fail because they don't account for the water content in the potatoes. If you boil your potatoes, mash them immediately, and throw in the fish, you’re inviting disaster. The steam gets trapped. That steam turns into water. That water turns your "cake" into a "slop."

You need a floury potato. Think King Edward or Russet. Avoid Waxy potatoes like Red Bliss for this specific task because they don't have the starch profile needed to "glue" the fish flakes together. According to J. Kenji López-Alt in his explorations of food science, the way you handle starch determines the final texture. When you over-work the mash, it becomes gluey. When you under-dry it, it falls apart.
Dry your potatoes. Seriously. After boiling, put them back in the hot pot for sixty seconds to let the residual moisture evaporate. It makes a massive difference.
The Secret Technique: How Do I Make Fish Cakes With Better Texture?
Texture is where the battle is won or lost. You want a crisp, golden exterior and a steaming, flaky interior.
Start with the Fish
Don't use raw fish directly in the mix if you're a beginner. It releases too much juice as it cooks, which ruins the structural integrity. Poach it gently in milk or water with a bay leaf and some peppercorns. Once it's just opaque, take it out. Let it cool.
The Ratio Rule
A good rule of thumb is 50/50. Equal parts fish and mashed potato. If you want a "luxury" cake, you can go 60% fish and 40% potato, but any higher and you’re going to need a lot of egg and breadcrumbs to keep it from crumbling.

- The Binder: One egg yolk is usually enough for a batch of four large cakes. Don't use the whole egg unless you're making a massive quantity; the white can make the mixture a bit too slippery.
- The Seasoning: Fresh parsley is non-negotiable. Dill is better if you're using salmon. A squeeze of lemon helps, but don't overdo the liquid.
- The Crunch: Panko breadcrumbs are superior to traditional breadcrumbs. They have more surface area, which means more crunch.
The Step-By-Step Workflow
- Prep the Spuds: Peel and cube your floury potatoes. Boil in salted water until tender. Drain them, then—this is the key—let them air dry in the colander for at least five minutes. Mash them while they are still warm but not scorching.
- Flake the Fish: While the potatoes dry, flake your poached fish. Keep the chunks relatively large. If you mash the fish into a paste, you’ve basically made a fish nugget. You want to see the flakes.
- Mix Gently: Fold the fish, herbs, zest, and egg yolk into the potato. Use a spatula, not a whisk. Be gentle.
- The Chill Phase: This is the part everyone skips because they're hungry. Don't. Form the cakes, put them on a tray, and stick them in the fridge for at least 30 minutes. This "sets" the starch and the proteins. A cold fish cake holds its shape in a hot pan; a warm one melts.
- Breading: Dredge in flour, dip in beaten egg, and roll in panko.
Shallow Fry vs. Deep Fry
Forget deep frying at home unless you have a dedicated fryer with perfect temperature control. Shallow frying in about half an inch of neutral oil (like grapeseed or vegetable) is the sweet spot.
You're looking for an oil temperature around 350°F (175°C). If you don't have a thermometer, drop a breadcrumb in. If it sizzles instantly, you’re good. If it sits there looking sad, wait.
Do not crowd the pan. If you put four cold fish cakes into a small skillet, the oil temperature will plummet. The cakes will then soak up the oil instead of searing. Result? Greasy mess. Cook in batches. Three minutes per side. That’s it.
Common Myths About Fish Cakes
People think you need expensive fish. You don't. In fact, firmer, cheaper white fish like Haddock or even Pollock often hold up better than delicate, pricey fillets.
Another misconception is that you need to add a ton of flour to the mix itself. Flour inside the cake makes it dense and "bready." Keep the flour on the outside.
Some people swear by adding mustard or capers. Honestly, that's great for flavor, but be careful with the moisture. If you add capers, pat them dry first. If you use mustard, use a thick Dijon, not a watery yellow mustard.
Scaling Up for Meal Prep
Fish cakes are the king of meal prep. You can freeze them beautifully.
If you're freezing them, do it after the breading stage but before frying. Wrap them individually in parchment paper and then toss them in a freezer bag. When you're ready to eat, don't thaw them. Just fry them straight from frozen, giving them an extra two minutes per side on a slightly lower heat so the center warms through without burning the crust.

Practical Next Steps for Your Kitchen
To master the art of the fish cake, start with a basic Salmon and Chive version. Salmon has a higher fat content which makes the cakes more forgiving if you slightly overcook them.
- Select your potatoes today: Grab a bag of Russets.
- Check your herb drawer: Freshness is the difference between a "cafeteria" fish cake and a "bistro" fish cake.
- Invest in a bench scraper: It makes portioning the cakes into equal sizes much easier, ensuring they all cook at the same rate.
- Dry the fish: Whatever fish you use, ensure it is patted dry with paper towels before it enters the mash.
The goal is a cake that shatters when you hit it with a fork but stays together until it reaches your mouth. Once you nail the potato-to-fish ratio and the cooling period, you'll never buy the frozen boxed versions again.
