How to Make Air Fryer Canned Sardine Cakes
Drain and Mash: Start by draining the canned sardines and placing them in a medium bowl. Use a fork to mash the sardines well, breaking them up until they’re thoroughly combined.
Mix Ingredients: Add the pork panko, roasted red pepper, egg, capers, garlic powder, black pepper, dill, lemon zest, and sliced scallion to the sardines. Mix everything together until all the ingredients are fully integrated, creating a flavorful mixture.
Shape Patties: Take the mixture and shape it into four patties, each about 2 ½ inches in diameter. Be careful not to make bigger patties, as they might crumble during cooking.
Prepare Air Fryer: Lightly mist the air fryer basket with cooking oil spray to prevent sticking. Arrange the patties in a single layer, ensuring they aren’t overcrowded, and spray the tops lightly as well.
Air Fry: Set your air fryer to 400 °F (200 °C) and cook the sardine cakes for 1012 minutes. Flip them halfway through cooking when they start to firm up, ensuring they cook evenly.
Serve and Enjoy: Once they’re a beautiful golden brown, remove the cakes from the air fryer and serve them warm with tartar sauce and lemon wedges, if desired.
Optional: Garnish with fresh herbs for an extra burst of flavor.

Ingredient Substitutions: If you don’t have pork panko, regular breadcrumbs can work, but they won’t be as keto-friendly as your Air Fryer Canned Sardine Cakes.

How to Store and Freeze Air Fryer Canned Sardine Cakes
Fridge: Store baked sardine cakes in an airtight container for up to 2-3 days. Keep them well-sealed to maintain freshness and moisture.
Freezer: For long-term storage, wrap each sardine cake individually in plastic wrap, then place them in a freezer-safe bag. They can be frozen for up to 2 months.

Air Fryer Canned Sardine Cakes Recipe FAQs
How do I choose the right canned sardines?
When selecting canned sardines, look for those packed in olive oil or water for the best flavor and texture. I always opt for sardines with bones for added calcium. Check the label for freshness and look for sardines without any dark spots; they should have a mild fish scent.
What s the best way to store leftover sardine cakes?
Store your baked sardine cakes in an airtight container in the fridge for up to 2-3 days. Ensure that they are sealed well to keep them moist. If you need to reheat them, the best way to do so is in the air fryer, where they’ll regain that delightful crispiness.
Can I freeze Air Fryer Canned Sardine Cakes?
Absolutely! To freeze, individually wrap each sardine cake in plastic wrap, then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 2 months. When you re ready to enjoy them, thaw overnight in the fridge and then pop them in the air fryer at 350 °F (175 °C) for about 5-7 minutes to re-crisp.
What if my patties fall apart while cooking?
If your sardine cakes crumble, it might be due to the patties being too large or a lack of binding ingredients. Ensure the patties are shaped to about 2 ½ inches in diameter and not overcrowded in the air fryer. A little extra pork panko may help hold them together better.
Are these sardine cakes safe for my pets?
While sardines are nutritious, it’s best to avoid feeding your pets any seasoned or mixed versions like these sardine cakes, which contain ingredients like garlic and capers that can be harmful to them. Always consult with your vet before introducing any new food to your pet s diet.
Can I adjust the recipe for dietary restrictions?
Very! For a vegan option, you can replace the egg with a flax egg by mixing 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and letting it sit for a few minutes until it becomes gel-like. Additionally, if you’re gluten-free, stick to pork panko or certified gluten-free breadcrumbs.
