Classic Fish Cakes
Fresh cod fillets, onion, garlic, and panko breadcrumbs are combined with a mayo-based sauce with dijon mustard and Old Bay to create these simple, but flavorful classic fish cakes. Paired with a homemade tartar sauce and lots of fresh herbs, these are perfect on a weeknight or for entertaining!
Ingredients in fish cakes
- fresh cod fillets (or other white flaky fish)
- Dijon mustard
- Old Bay (classic flavor of fish cakes comes from this ingredient!)
- lemon zest
- kosher salt
- freshly ground black pepper
- panko breadcrumbs
- fresh herbs (the more the better!) — I love to use a combination of parsley, dill, and chives
How to make fish cakes
Start by baking a couple pieces of fresh cod fillets. Season with only olive oil, salt, and pepper. The fish will get a boost of flavor from the other ingredients, including a killer sauce and lots of fresh herbs.
Forming fish cakes
The key takeaway when forming fish cakes is to mix the sauce first, then add in the remaining ingredients. The goal is to keep as big of flakes of the fish as you can. This will create a wonderful texture for the cod cakes!
Once the wet ingredients are mixed and you’ve added in the sautéed onions, breadcrumbs, fresh herbs, and flaked fish, you can use either your hands or a spatula to stir very gently until just combined.
From here, allow the mixture to rest for about 1 hour in a refrigerator. Then, use a large cookie scoop to portion out equal size patties. Use your hands to gently press each fish cake together, using as little pressure as you can so as not to crush them, then set aside until ready to cook.
Homemade tartar sauce
If you’re making fish cakes from scratch, go ahead and take the 5 minutes needed to make homemade tartar sauce as well. The flavor blows any store-bought variety out of the water!
- 1 cup mayonnaise
- 2 Tbsp sweet pickle relish
- 1 tsp Dijon mustard
- 2 small shallots, diced
- juice from 1 lemon (about 2-3 Tbsp)
- ¾ tsp kosher salt
- ¼ tsp freshly ground black pepper
To make: combine mayonnaise, relish, Dijon mustard, shallots, lemon juice, salt, and pepper in a large bowl, then whisk to combine. Refrigerate until ready to use. This is the best homemade tartar sauce (and so simple!). It goes well with everything from fish cakes, to fish and chips, to seafood burgers (how delicious do these salmon burgers look?!)
Using other types of fish
I find cod fillets to be an exceptionally economical fish that are also easily accessible across many parts of the country, but if you can’t get your hands on any or you just don’t want to use cod, the following would make a great substitute: branzino, tilapia, flounder, red snapper, sole, halibut, or haddock. These are all white, flaky fish (and they’re each delicious in their own way!).
Can fish cakes be frozen?
Yes, fish cakes freeze beautifully! You have two options: first, you can cook the fish cakes as instructed below, then allow to cool completely to room temperature. Place them on a sheet tray in a freezer until solid, about 2 hours, then store in an airtight, freezer-safe container.
Alternatively, you could form the fish cakes and freeze them before cooking.
Whichever method you choose, make sure fish cakes have enough time to fully defrost (overnight in a refrigerator) before you go to reheat or cook them!
Reheating frozen fish cakes
To reheat cooked frozen fish cakes, allow to to defrost overnight in a refrigerator, then place in a 350F oven until golden brown and crispy, about 8-10 minutes.
What to serve with cod cakes
When I serve fish cakes, I often keep the meal very simple: a big green salad piled high on a plate, a few fish cakes on top, an abundance of fresh herbs, a couple lemon wedges, and my own personal bowl of homemade tartar sauce.
If you want to add a veggie side dish, my roasted broccolini is the BEST. We eat this at least 2x a week!
Are these gluten-free?
If you substitute gluten-free breadcrumbs for traditional breadcrumbs, then YES — the rest of this recipe is gluten-free!
If you want your fish cakes to be extra, drizzle them with a touch of high quality extra virgin oil and then sprinkle with a pinch of flaky sea salt just before serving.
Squeeze with fresh lemon juice, then DIG IN.

Classic Fish Cakes
- 2 lbs cod fillets or other white flaky fish (such as halibut, grouper, or sole), patted dry
- 3 Tbsp butter unsalted
- 4 cloves garlic minced
- 1 medium onion diced
- ¼ cup mayonnaise
- 1 Tbsp dijon mustard
- 2 large eggs
- 1 Tbsp Old Bay seasoning
- 2 ½ tsp kosher salt divided
- ½ tsp freshly ground black pepper
- 1 ½ cups panko breadcrumbs
- 2 Tbsp fresh parsley chopped
- 2 Tbsp dill chopped
- 1 Tbsp chives thinly sliced
- Zest of 1 lemon
- 2 Tbsp olive oil
- 2 Tbsp neutral oil such as avocado, grapeseed, or canola oil
- lemon wedges
- arugula or mixed greens
- additional fresh herbs for garnish
- Preheat oven to 375F. Line a rimmed baking sheet with parchment paper, then place cod fillets on top. Drizzle with 2 Tbsp olive oil, 1 tsp kosher salt, and ¼ tsp freshly ground black pepper. Cook for 12 minutes, or until fish is an internal temperature of 145F. Set aside until cool enough to handle fish with your hands, about 5-10 minutes.
- Meanwhile, melt butter in a skillet over medium-high heat. Add garlic and onion and sauté until translucent, about 3-4 minutes. Set aside.
- In a large bowl, whisk together mayonnaise, dijon mustard, eggs, Old Bay, 1 ½ tsp kosher salt, and ¼ tsp black pepper. To this add sautéed onion and garlic, panko breadcrumbs, fresh herbs, and lemon zest. Flake the slightly cooled fish with your fingers or two forks, being careful to keep the flakes as large as possible. Gently combine all ingredients together until homogenous and evenly mixed. Place fish cake mixture in a refrigerator to cool completely, about 1 hour.
- When ready, use a large cookie scoop to form equal sized patties. Press together gently in your hands to flatten and round each out to about a height of 1".
- Heat grapeseed (or other neutral oil) over medium-high heat in a large skillet or on a griddle. When hot, add fish cakes and cook 3-5 minutes per side, being careful to flip each gently so they don't break apart. Serve on top of arugula or mixed greens with lemon wedges, some additional fresh herbs for garnish, and a sprinkling of flaky sea salt if you've got it!
