Equipment You’ll Need

• Large mixing bowl
• Fork
• Large non-stick skillet or cast-iron pan
• Fish spatula or other thin spatula
• Measuring cups and spoons
• Shallow dish or plate
• Cutting board and knife

Ingredients

• 2 (3.75 ounce) cans sardines in oil, undrained
• 1 large egg, lightly beaten
• 1/2 cup panko breadcrumbs, plus 1/4 cup for coating
• 3 tablespoons mayonnaise
• 2 scallions, finely chopped (both white and green parts)
• 2 tablespoons fresh parsley, finely chopped
• 1 tablespoon Dijon mustard
• 1 teaspoon lemon zest
• 1 tablespoon fresh lemon juice
• 1/2 teaspoon Old Bay seasoning (or paprika)
• 1/4 teaspoon black pepper
• 2 tablespoons olive oil or avocado oil, for frying

Instructions

1. Prepare the Fish: Open the cans of sardines and pour the entire contents, including the oil, into a large mixing bowl. The oil is packed with flavor and omega-3s. Using a fork, gently mash the sardines until they are broken up but still have some texture. Don’t turn it into a paste.
2. Combine Ingredients: To the bowl with the mashed sardines, add the beaten egg, 1/2 cup of panko breadcrumbs, mayonnaise, chopped scallions, parsley, Dijon mustard, lemon zest, lemon juice, Old Bay seasoning, and black pepper.
3. Mix Gently: Using the fork or a spatula, gently fold all the ingredients together until just combined. Overmixing can lead to dense, tough cakes. The mixture should be moist enough to hold its shape.
4. Form the Patties: Spread the remaining 1/4 cup of panko breadcrumbs onto a shallow dish or plate. Divide the sardine mixture into 8 equal portions and shape them into patties about 1-inch thick. Gently press each side of the patties into the panko to create a light, even coating. This will ensure a super crispy exterior.
5. Chill (Optional but Recommended): Place the formed patties on a plate and refrigerate for at least 10-15 minutes. This step is crucial for helping the cakes firm up and hold their shape during cooking.
6. Cook the Cakes: Heat the olive oil in a large non-stick skillet over medium-high heat. Once the oil is shimmering, carefully place the chilled patties in the pan, ensuring not to overcrowd it (cook in batches if necessary).
7. Fry to Perfection: Cook for 4-5 minutes per side, until they are a deep golden brown and beautifully crisp. Use a thin fish spatula to flip them carefully.
8. Serve Immediately: Remove the cakes from the skillet and place them on a paper towel-lined plate for a moment to drain any excess oil. Serve hot with your favorite sauce and a wedge of lemon.

Expert Cooking Tips

• Don’t Drain the Oil: The oil from the canned sardines is full of flavor and healthy fats. Incorporating it into the mixture adds moisture and depth.
• The Chill is Key: Don’t skip the chilling step. Even 10 minutes in the fridge makes a world of difference in preventing the cakes from falling apart in the pan.
• Panko for Crunch: While other breadcrumbs work, panko breadcrumbs are specifically designed to be lighter and airier, creating a much crispier crust.
• Medium-High Heat is Your Friend: Ensure the pan and oil are properly heated before adding the cakes. This creates an instant sear, locking in moisture and preventing the cakes from absorbing too much oil.
• Handle with Care: Use a thin, flexible spatula for flipping. These cakes are delicate, and a gentle hand will keep them intact.

Substitutions and Variations

For a different flavor profile, you can use canned salmon or mackerel. If you don’t have panko, crushed saltine crackers or regular breadcrumbs are a good substitute. Fresh dill can be used in place of parsley for a brighter taste. For a gluten-free version, simply use certified gluten-free panko breadcrumbs.

Common Mistakes to Avoid

The most common mistake is overmixing the base, which can result in a pasty, dense texture. Mix only until the ingredients are combined. Another pitfall is making the patties too wet. If your mixture feels overly soggy, add an extra tablespoon of panko to help bind it. Finally, avoid frying on a heat that’s too low, as the cakes will absorb oil and become greasy rather than crisp.

Serving Suggestions

Serve these incredible fish cakes as you would a classic crab cake. A dollop of tartar sauce, remoulade, or a simple garlic aioli is a must. A generous squeeze of fresh lemon juice brightens all the flavors. For a complete meal, pair them with a simple arugula salad, creamy coleslaw, or roasted asparagus. They also make fantastic sliders on toasted brioche buns with a crisp lettuce leaf.

Storage and Reheating Tips

Store any leftover cooked cakes in an airtight container in the refrigerator for up to 3 days. To reheat and restore their signature crispiness, place them in a 375°F (190°C) oven or an air fryer for 5-7 minutes. Microwaving is not recommended as it will make the coating soggy.

Frequently Asked Questions

Are the tiny bones in the sardines edible?

Yes, absolutely! The canning process makes the bones completely soft and edible. They are an excellent source of calcium and you won’t even notice them once the sardines are mashed.

Can I make these in an air fryer?

Yes, these work beautifully in an air fryer. Preheat your air fryer to 400°F (200°C). Spray the basket and the tops of the cakes with a light coating of cooking spray. Cook for 8-10 minutes, flipping halfway through, until golden and crisp.

Can I prepare the fish cake mixture ahead of time?

You can prepare the mixture up to 24 hours in advance. Keep it covered tightly in the refrigerator. When you’re ready to cook, form the patties, coat them in panko, and pan-fry as directed.
