Crispy Cod Fish Cakes with Lemon Dill Sauce

Cod fish cakes are the kind of weeknight dinner that feels a little special, but comes together fast with a few pantry staples.

Crispy on the outside, tender and flaky inside, these patties turn a simple fillet of cod into something you’ll want to make on repeat. A quick lemon dill sauce on the side brightens everything up.

Why These Fish Cakes Work

The panko crust is the real star here. It gives you a crackly, golden shell that stays crisp way longer than a flour coating ever would.

Inside, the cod stays in distinct, moist flakes, held together with just enough creamy potato. That means every bite has both crunch and softness, and the fresh dill and lemon zest keep it from ever tasting heavy.

Ingredients

• 1 lb cod fillets, skinless: fresh or frozen and thawed, patted dry
• 1 lb russet potatoes: peeled and cut into 2-inch chunks
• 1 large egg: lightly beaten
• 1/3 cup panko breadcrumbs: plus extra for coating
• 2 tbsp chopped fresh dill: divided
• 1 tsp lemon zest
• 1/2 tsp salt: plus more for the potato water and sauce
• 1/4 tsp black pepper
• 2–3 tbsp vegetable oil: for frying
• 1/2 cup plain Greek yogurt, full-fat: for the sauce
• 1 tbsp lemon juice: for the sauce

Variations and Substitutions

• Swap the protein: Haddock or salmon work beautifully here; just flake them the same way and taste for salt.
• Herb swap: Chives or parsley are just as fresh if you’re out of dill.
• No panko: Regular dry breadcrumbs will coat them, but you’ll lose some of that airy crunch.
• Dairy-free option: Skip the yogurt sauce and serve with a squeeze of lemon and a dollop of vegan mayo.
• Add a little heat: A pinch of cayenne in the mixture gives a gentle warmth without overwhelming the cod.

If you enjoy seafood patties, our Crispy Salmon Patties are another quick favorite.

How to Make Crispy Cod Fish Cakes

Step 1: Poach the Cod

Place the 1 lb cod in a large skillet and add enough cold water to just cover the fillets. Set the pan over medium heat and bring to a gentle simmer, then reduce the heat to low and cook for 5 to 7 minutes.

The fish is ready when it turns opaque all the way through and flakes easily when you press it with a fork. Lift the fillets out with a slotted spatula and set them aside to cool for a few minutes while you start the potatoes, then flake them gently into large pieces with two forks.

Step 2: Boil and Mash the Potatoes

Drop the 1 lb of peeled potato chunks into a pot and cover them with cold water by about an inch. Add a generous pinch of salt, bring to a boil, and cook until the potatoes are tender all the way through, about 12 to 15 minutes.

Drain them well, then return the potatoes to the dry pot for a minute over low heat to steam off any extra moisture. Mash them with a fork or a ricer until smooth, and let the mash cool until it’s just warm before you add it to the fish.

Step 3: Mix the Fish Cake Filling

In a large bowl, combine the flaked cod, cooled mashed potato, 1 beaten egg, 1/3 cup panko, 1 tbsp of the chopped dill, 1 tsp lemon zest, 1/2 tsp salt, and 1/4 tsp pepper. Fold everything together with a light hand, just until it starts to come together.

You want to see visible pieces of cod in the mix. Stop as soon as the mixture holds its shape when you press a little against the side of the bowl; overworking it will make the cakes dense.

Step 4: Shape and Coat the Patties

Scoop about 1/3 cup of the mixture and gently form it into a patty that’s about ¾ inch thick. Spread a shallow layer of extra panko on a plate, then press each patty lightly into the crumbs to coat both sides.

You’ll end up with 6 to 8 cakes. Try to keep the panko coating even and not too thick, a light press is all they need, or the crust can slide off during frying.

Step 5: Pan-Fry the Cakes

Pour 2 tbsp of oil into a large skillet and set it over medium heat. When the oil shimmers, add the patties in a single layer, working in batches to avoid crowding, and cook for 4 to 5 minutes on each side.

Look for a deep, golden brown crust and a steady, gentle sizzle. If the bottoms are browning too fast, lower the heat a touch and give the pan a minute to settle before flipping.

Step 6: Serve with Lemon Dill Sauce

While the last batch fries, stir together the 1/2 cup Greek yogurt, 1 tbsp lemon juice, the remaining 1 tbsp chopped dill, and a pinch of salt in a small bowl.

Spoon the sauce onto plates, nestle the hot fish cakes right on top, and serve while they’re still crackling hot from the pan.

A Few Tips for Perfect Fish Cakes

• Cool the potatoes completely before mixing them in. Warm mash can make the mixture too soft to hold its shape, so it’s worth the extra ten minutes.
• A cast iron skillet gives the most even heat and the crispiest crust. Nonstick works too, but you may need an extra minute per side.
• If the mixture feels loose or the patties seem fragile, pop the bowl in the fridge for 15 minutes before you shape them. The chill firms everything up fast.
• Fresh cod has a cleaner, milder taste than frozen in these cakes. If you use frozen, just be sure to pat it very dry after thawing.

Cook times can shift a little depending on your pan:

Storing and Reheating Leftovers

• Refrigerate: Pack cooled cakes in an airtight container and they’ll keep for up to 3 days.
• Reheating: To bring the crunch back, place them on a baking sheet in a 375°F oven or air fryer for 6 to 8 minutes. A quick pan-fry over medium heat works too. Skip the microwave here, it makes the panko soft.

What Goes Well with These Fish Cakes

A lemony green salad is a natural partner; the acidity cuts through the richness and takes zero extra cooking. Roasted asparagus with a little garlic butter is another easy side while the cakes are frying. If you want something crisp and cool, a simple vinegar-based coleslaw with shredded cabbage and carrots balances the warm, savory cakes perfectly.

Frequently Asked Questions

Can I bake the fish cakes instead of frying them?

Yes. Place them on a greased baking sheet and bake at 400°F for about 15 to 18 minutes, flipping once. They won’t get quite as crisp, but they’ll still be golden and delicious.

Can I freeze the patties?

You can freeze the shaped, uncooked patties on a tray until solid, then transfer them to a bag. Fry them straight from frozen, adding a couple of extra minutes per side.

My cakes fell apart in the pan. What went wrong?

Too much moisture is usually the culprit. Make sure the potatoes are well-drained and the cod is patted dry after poaching. Chilling the mixture before shaping also helps them stay together.

Can I use frozen cod fillets?

Absolutely, just thaw them completely in the fridge and press out any extra liquid with paper towels before poaching so the mixture doesn’t turn watery.

• 1 tsp lemon zest
• 1/2 tsp salt, plus more for potato water and sauce
• 1/4 tsp black pepper
• 2–3 tbsp vegetable oil, for frying
• 1/2 cup plain Greek yogurt, full-fat

Method

 

1. Poach cod in a skillet of simmering water for 5–7 minutes, then drain, cool, and flake into large pieces.
2. Boil the potato chunks in salted water for 12–15 minutes until tender, drain, and mash until smooth. Let cool until just warm.
3. Gently fold the flaked cod, mashed potato, egg, 1/3 cup panko, 1 tbsp dill, lemon zest, salt, and pepper together just until combined.
4. Shape into ¾-inch-thick patties and press both sides lightly in extra panko to coat.

6. Stir together the yogurt, lemon juice, remaining 1 tbsp dill, and a pinch of salt. Spoon onto plates and serve with the hot cakes.

Notes

You can shape the patties a few hours ahead and keep them covered in the fridge. Just give them a fresh press in panko right before frying so the coating stays dry and crisp.
