Air Fryer Fish Cake Recipe

I think I’ve finally found the perfect way to make fish cakes. Do you love them as much as I do? For years, I was a little sad when my homemade ones turned out… well, a bit mushy. Or if I tried to pan-fry them, they would either fall apart or soak up way too much oil. Everything changed when I cooked them in my air fryer. It was a total game-changer!

These Air Fryer Fish Cakes are everything you dream of: a perfectly golden, crispy, crunchy outside that gives way to a fluffy, tender, and savory inside. They’re packed with flaky fish, creamy potatoes, and bright herbs, with a little zip from fresh lemon. They taste just like the ones from a cozy seaside restaurant, but you can make them right in your own kitchen.

The best part? There’s no messy deep-frying! The air fryer does all the work, circulating hot air to get them crispy with just a tiny bit of oil. It’s so much easier, healthier, and the cleanup is a breeze.

In this post, I’m going to walk you through all my simple tips to make sure your fish cakes turn out perfectly every single time. We’ll cover everything from the best fish to use to the secret for getting them extra crispy. Let’s get cooking!

Why You’ll Love This Recipe

There are so many reasons to love this recipe, but here are my absolute favorites:

• Unbelievably Crispy! The air fryer creates a crunchy, golden-brown Panko crust that’s just perfect, while the inside stays wonderfully soft and moist.
• So Much Easier (and Cleaner!): Forget the mess, splatter, and lingering smell of deep-frying. The air fryer contains it all and makes cleanup so simple.
• A Healthier Way to Fry: You get all that amazing crunch and restaurant-quality texture using just a light spritz of oil, not a whole pot of it.
• Great for Using Leftovers: This is my favorite way to use up leftover mashed potatoes or a bit of cooked fish. It’s a “waste-not, want-not” superstar.
• Ready in Minutes: Once the cakes are prepped, they cook in about 10-12 minutes, making them a fantastic quick lunch or light dinner.

Here’s what you will need

The magic of this recipe is how simple, wholesome ingredients come together to make something so special. You probably have most of what you need in your kitchen already!

• Flaky White Fish – This is the star of the show. I love using cod, haddock, or pollock. You can use fresh fillets that you poach or bake, or even good-quality leftover cooked fish from another meal.
• Potatoes – We need Russet potatoes (or any starchy potato like Maris Piper) to make fluffy mashed potatoes. This is the binder and what makes the inside so tender. Using leftover cold mashed potatoes is a huge time-saver here!
• Panko Breadcrumbs – This is the secret to the crisp. Panko is a Japanese-style breadcrumb that’s lighter and gets much crunchier than regular breadcrumbs. We’ll use some inside the cakes and some for the crunchy outer coating.
• Egg – We’ll use one large egg inside the mixture to bind everything together so the cakes don’t fall apart. We’ll use another one for the breading station.
• Flavor Makers – This is what makes them taste so bright and fresh! We’ll need fresh parsley (dill is also amazing!), lemon (for both the zest and the juice), Dijon mustard for a little tang, and a shallot (or green onions) for a mild, savory flavor.
• The “Breading Station” – To get that perfect, shatter-proof crust, we’ll dip the cakes in a little all-purpose flour, a beaten egg, and finally, the Panko.
• Basics – Don’t forget Kosher salt, freshly ground black pepper, and a little olive oil spray or cooking spray. This is key to helping the Panko get golden and crispy in the air fryer.

How to Make This Dish: Step-by-Step Guide

Making these fish cakes is so much fun, and it’s easier than you think. We’ll make the mixture, form the cakes, and then let the air fryer work its magic.

1. Make the Fish Cake Mixture

The first step is to get your main ingredients ready. You’ll want your cooked fish flaked into small pieces and your mashed potatoes to be cold—this is important! Cold potatoes will help the cakes hold their shape.

In a large bowl, combine the flaked fish, cold mashed potatoes, 1/4 cup Panko, the beaten egg, chopped parsley, shallot, Dijon mustard, lemon juice, and lemon zest. Gently fold everything together with a spatula until it’s just combined. You want to be gentle so you still have some nice flakes of fish in there.

Pro Tip: Over-mixing can make the potatoes gummy and the fish break down too much. Stop mixing as soon as everything is just blended together.

2. Form and Chill the Cakes

Now, we’ll shape the patties. Line a baking sheet with parchment paper. Use your hands (or an ice cream scoop for even portions!) to form the mixture into patties. This recipe should make about 6-8 medium-sized cakes.

Place the formed cakes on the prepared baking sheet. This next step is my secret weapon: Chill the cakes in the refrigerator for at least 30 minutes (or up to 4 hours). Chilling solidifies the cakes, which is the key to making sure they don’t fall apart during breading or cooking.

3. Set Up Your Breading Station

While the cakes are chilling, get your breading station ready. You’ll need three shallow bowls or plates:

• Bowl 1: Add the 1/2 cup of all-purpose flour.
• Bowl 2: Add the other beaten egg.
• Bowl 3: Add the 1 cup of Panko breadcrumbs and season them with a pinch of salt and pepper.

4. Bread the Fish Cakes

Once the cakes are chilled and firm, it’s time to bread them. Take one cake at a time and:

1. Dredge in Flour: Lightly coat it in the flour, tapping off any excess.
2. Dip in Egg: Dip it into the beaten egg, letting any extra egg drip off.
3. Coat in Panko: Press the cake into the Panko breadcrumbs, making sure to coat all sides evenly.

Place the breaded cake back on the parchment-lined baking sheet. Repeat with the remaining cakes.

5. Time to Air Fry!

First things first, preheat your air fryer to 400°F (200°C). This is essential for getting that crispy crust right away.

Lightly spray the air fryer basket with olive oil or cooking spray. Carefully place the fish cakes in the basket in a single layer. Make sure they aren’t touching—you want the hot air to be able to circulate all around them. You may need to cook these in two batches.

Lightly spray the tops of the fish cakes with more olive oil spray. This is what helps the Panko turn that beautiful golden-brown color.

Air fry for 10-12 minutes, flipping the fish cakes over very gently about halfway through (around the 6-minute mark).

Your fish cakes are done when they are beautifully golden brown and crispy on the outside and heated through in the center.

6. Serve and Enjoy

Carefully remove the fish cakes from the air fryer (they will be hot!). Let them cool for just a minute. They are best served immediately while they’re at their crispiest, with a squeeze of fresh lemon and your favorite dipping sauce.

How to Store, Reheat and Freeze

One of the best things about this recipe is that it’s great for making ahead!

• To Store (Leftovers): Place any leftover cooked fish cakes in an airtight container. They will keep in the refrigerator for up to 3 days.
• To Freeze (Uncooked): You can freeze the fish cakes after breading them. Place the breaded, uncooked cakes on a baking sheet and “flash freeze” them for 1-2 hours until solid. Then, transfer them to a freezer-safe bag or container. They will last in the freezer for up to 3 months. You can cook them straight from frozen! Just add about 4-5 extra minutes to the air frying time.
• To Reheat: The air fryer is, by far, the best way to reheat these! It brings the crispiness right back. Just place the cold fish cakes in the air fryer at 370°F (185°C) and cook for 3-5 minutes, or until they are hot and crispy again. I would avoid the microwave, as it will make the breading soggy.

Variations to Try

This recipe is a wonderful starting point. Here are a few ways to change it up!

• Spicy Fish Cakes: Add a little kick! Mix in 1/2 teaspoon of red pepper flakes or a finely chopped jalapeño (seeds removed) to the fish cake mixture. A spicy sriracha mayo for dipping is also delicious.
• Gluten-Free Fish Cakes: This is an easy swap! Use your favorite gluten-free Panko breadcrumbs (or crushed gluten-free cornflakes) for the breading. For the flour dredge, use a 1-to-1 gluten-free all-purpose flour.
• Herb-Infused: Change up the herbs! Instead of (or in addition to) parsley, try using fresh dill, chives, or even a little tarragon. Each one gives the cakes a completely different, fresh flavor.
• Use Canned Fish: To make this even easier and more budget-friendly, you can swap the fresh fish for canned fish. About 12-14 oz (350-400g) of good-quality canned salmon or tuna (drained very well!) will work perfectly.

What To Serve With This Dish

These fish cakes are so versatile—they can be a light lunch, a tasty appetizer, or a full-on dinner. Here are some of my favorite ways to serve them:

• With a Dipping Sauce: This is a must! A simple tartar sauce is classic, but I also love a lemon-dill yogurt sauce (just Greek yogurt, lemon juice, fresh dill, and a pinch of salt) or a spicy aioli (mayonnaise, garlic, and a dash of sriracha or hot sauce).
• On a Bed of Greens: Make it a wonderful, light meal by serving two fish cakes on top of a simple arugula salad tossed in a lemon vinaigrette. The peppery greens are a perfect contrast.
• As a Main Course: To make it a more filling dinner, serve the fish cakes with a side of roasted asparagus (you can make it in the air fryer, too!), a pile of creamy coleslaw, or some simple steamed green beans.
• With Fries: For that classic “fish and chips” vibe, you can’t go wrong with a side of sweet potato fries or regular fries, also made in the air fryer!

Helpful Pro Tips and Tricks

Over the years, I’ve learned a few little things that take these fish cakes from good to great. Here are my top tips:

• Dry is Your Friend! For the best, crispiest cakes, your ingredients need to be relatively dry. Make sure you drain your cooked fish well and, most importantly, use cold, leftover mashed potatoes. Warm or “wet” mashed potatoes are the #1 reason fish cakes fall apart.
• Don’t Crowd the Basket: This is the golden rule of air frying! You need to leave space between the fish cakes so the hot air can circulate and crisp up all the edges. Cook in batches if you have to—it’s worth it!
• Be Gentle: When you’re mixing the fish cake mixture and flipping them in the air fryer, be gentle. You want to keep those nice flakes of fish intact, not turn the mixture into a paste.
• Don’t Skip the Chill Time: I know, it’s tempting to rush, but that 30-minute chill in the fridge is what solidifies the fats and starches in the patties. This step is crucial for making sure they hold their shape and don’t fall apart.
• The Double Panko Trick: If you want extra thick, crunchy crust, you can double-dip! After the first Panko coating, dip them back into the egg, and then back into the Panko again. It’s a little extra work but creates an incredible crust.

Frequently Asked Questions

Here are answers to a few common questions I get about this recipe.

Can I make these fish cakes gluten-free?

Absolutely! This is a very easy recipe to adapt. Simply swap the all-purpose flour for a 1-to-1 gluten-free baking blend, and use your favorite brand of gluten-free Panko breadcrumbs for the coating. The texture will be just as crispy and delicious.

What is the best fish to use for fish cakes?

You want a firm, flaky white fish. My top choices are cod, haddock, pollock, or even halibut. You can also use salmon for a richer, more flavorful fish cake. The key is to avoid overly delicate fish that might get lost or turn to mush.

Why did my fish cakes fall apart?

This is the most common problem, and it usually comes down to one of two things:

1. The mixture was too wet: This happens if your mashed potatoes were warm or “watery,” or if your cooked fish wasn’t drained properly. Using cold, firm mashed potatoes is the best way to prevent this.
2. You skipped the chill time: Chilling the patties in the fridge for at least 30 minutes is so important. It helps them firm up and bind together, so they don’t fall apart when you bread or flip them.

Can I use canned fish?

Yes, you can! This is a great, budget-friendly option. A good-quality canned salmon (about 12-14 ounces) or canned tuna works wonderfully. The most important step is to drain it extremely well before flaking it and adding it to the bowl. Any extra moisture is the enemy of a firm fish cake.

Last Bites

And that’s all there is to it! You’ve just made the most delicious, crispy, and flavorful fish cakes, all with the magic of your air fryer.
