Crispy Mackerel Potato Cakes

One chilly evening, I found myself craving something comforting yet lively, and the idea of transforming leftover potatoes and smoked mackerel into golden, crispy cakes came almost by accident. The sizzle from the skillet and the sharp aroma of dill caught the attention of my neighbor, who kindly dropped in with a lemon in hand. Making these little cakes always brings a certain anticipation, knowing the contrast between crunchy crust and soft, flavorful center will be just right. It’s the kind of dish that feels as at home at a lazy Sunday lunch as it does for a quick weeknight supper. The dill yogurt is a bright, tangy finishing touch that livens up each bite and never fails to pull it all together.

I still laugh remembering the time I first served these to friends on a stormy Saturday–our conversation dissolved into a happy silence as everyone focused on that first crunch. Someone asked for the recipe before the last cake disappeared, which I took as the ultimate compliment. That shared, slightly chaotic kitchen energy pushed me to write down the steps I’d usually make by intuition. Admittedly, there’s a certain delight in seeing mackerel skeptics become full-blown fans by dessert. When the cakes come off the pan, it feels like I’m sharing a small victory with anyone at the table.

Ingredients

• Potatoes (400g, floury): Going for a floury potato like Maris Piper or Russet ensures your cakes are fluffy, and letting them steam-dry after boiling really prevents a soggy mixture.
• Smoked mackerel fillets (2, about 200g): It’s worth picking out all the bones and flaking carefully by hand – the depth of flavor smoked mackerel brings is unbeatable.
• Shallot (1 small): Finely chopped shallot adds sweetness and a subtle bite that cuts through the richness.
• Fresh chives (2 tbsp): Chives give a gentle oniony lift, though in a pinch, I’ve swapped them for parsley or spring onions and been happy with the result.
• Egg (1): Egg binds everything together, but mix gently to keep the cakes tender rather than dense.
• All-purpose flour (2 tbsp, plus extra): Just enough flour helps bring it all together–dusting the cakes before frying adds to that irresistible crisp surface.
• Salt and black pepper: Go with your taste instinct, and don’t shy away from a bold seasoning–especially with potatoes.
• Zest of 1 lemon: A little zest brightens everything; I’ve learned not to skip this, even if I’m tempted.
• Vegetable oil (3–4 tbsp): Neutral oil is best for frying, and you want enough to cover the pan generously but not overwhelm the cakes.
• Greek yogurt (150g): Thick Greek yogurt makes the sauce creamy without feeling heavy.
• Fresh dill (2 tbsp): Dill brings a burst of freshness–snipping it straight into the yogurt reminds me of home gardens in spring.
• Lemon juice (1 tsp): Just a splash is enough to wake up the sauce.
• Salt and pepper (for sauce): Adjust the sauce until it’s perfectly tangy and savory for you.

Instructions

Start with the potatoes:

Pop the diced potatoes in a saucepan of salted water and boil until they’re fork-tender and almost falling apart, about 12–15 minutes; after draining, let them steam while you gather your other ingredients.

Mash and cool:

Once they’re dry, mash the potatoes until smooth–a few little lumps here and there are just fine. Leave to cool so the egg won’t scramble in the mix.

Mix in the mackerel and aromatics:

In a big bowl, gently combine flaked mackerel, shallot, chives, lemon zest, egg, flour, salt, and pepper with the potatoes; try not to overwork it, just enough for everything to hold together.

Shape into cakes:

Divide the mixture into 8, roll gently into balls, then flatten slightly into thick cakes; dust each side lightly with flour and set on a plate ready for frying.

Get frying:

Heat vegetable oil in your skillet over medium heat, then add the cakes in batches, giving them 3–4 minutes per side until golden and crisp; transfer each one to kitchen paper as you go.

Make the dill yogurt:

Stir together Greek yogurt, dill, lemon juice, and a pinch of salt and pepper in a small bowl; taste and adjust seasoning as needed so it’s punchy but balanced.

Serve and enjoy:

Arrange the crisp potato cakes on a platter and serve with generous spoonfuls of dill yogurt – preferably while everything’s still warm.

Save

Every time these cakes come to the table with a bowl of dill yogurt on the side, the meal feels a little celebratory. Somewhere between the crunchy first bite and the second helping, it always turns into a highlight of the week, not just another dinner.

Choosing the Best Ingredients

The subtle differences between floury and waxy potatoes really do matter here–floury ones keep the cakes from being stodgy. With smoked mackerel, it pays to check the fillets are well de-boned and not too oily, as that can affect both texture and taste. Fresh herbs elevate the whole dish, so I always grab an extra handful just in case.

How to Fry Without Stress

Heating the oil just to the right shimmer before frying helps prevent sticking and soggy bottoms. I like to test with a tiny piece of mixture first to make sure the sizzle is lively but not furious. Using a wide spatula gently to turn them means you’ll keep those lovely crisp edges intact.

Mix and Match Your Flavors

I’ve started experimenting with swapping smoked mackerel for canned when I want something lighter, and it works surprisingly well. Changing up the herbs or even adding a little finely chopped caper to the yogurt offers an easy twist that can match your mood or what’s hiding in your fridge.

• Dusting your hands with flour makes shaping much simpler.
• If you want a gluten-free version, just use your go-to blend and the results will still be crisp.
• Don’t forget to zest the lemon before you juice it – it’s so much easier that way.

Save

Whether you share these crispy mackerel potato cakes at a gathering or keep them all to yourself, they promise a moment of pure comfort. Don’t be surprised if requests for the recipe come before you even finish the last bite.
