Simple Seafood bliss - Leftover Fish Cakes

Ingredients for this Leftover Fish Cakes:

  • Leftover fish (or canned Tuna)
  • Leftover Mashed potatoes (or freshly mashed)
  • Onion
  • Celery
  • Bell pepper (any colour)
  • Garlic
  • Mayonnaise
  • Dijon mustard
  • Lemon juice
  • Dried dill (or fresh dill)
  • Salt and pepper to taste
  • Eggs
  • Vegetable oil for frying

No leftover fish? No Worries!

If you find yourself without leftover fish but still crave the delightful flavours of fish cakes, no worries! You can effortlessly substitute fresh fish with canned tuna to create equally delicious tuna cakes. Canned tuna offers a convenient alternative, making this recipe accessible anytime you desire a taste of the sea. Simply replace fish with 3 cans of tuna (drained).

Side Dish Suggestions for this Fish Cake Recipe:

  • Green Salad:
    A simple green salad with fresh lettuce, cherry tomatoes, cucumber slices, and a light vinaigrette dressing complements the fish cakes well. You can also add some olives or capers for extra flavour.
  • Coleslaw:
    My personal favourite, creamy coleslaw made with cabbage, carrots, and a tangy dressing adds a refreshing and crunchy contrast to the crispy fish or tuna cakes.
  • Roasted Vegetables:
    Making a main meal of it. Roasted vegetables, such as asparagus, broccoli, or Brussels sprouts, make a nutritious side. Toss them with olive oil, salt, and your favourite seasonings before roasting.
  • Mashed Peas:
    A simple but tasty side dish, mashed peas seasoned with a bit of butter, salt, and pepper provide a nice balance to the fish cakes.
  • Corn on the Cob:
    Grilled or boiled corn on the cob with a sprinkle of salt and a pat of butter is a classic side that pairs well with seafood.
  • Sweet Potato Fries:
    Baked sweet potato fries offer a sweet and savoury contrast to the fish or tuna cakes. Season them with a pinch of paprika or cinnamon for extra flavour.
  • Quinoa Salad:
    A cold quinoa salad with diced vegetables, fresh herbs, and a lemony dressing is a nutritious and refreshing option.
  • Garlic Bread:
    A slice of warm garlic bread or a garlic butter baguette can be a comforting side to soak up any extra sauce or dressing.
  • Fruit Salsa:
    A fruity salsa made with diced mango, pineapple, or citrus fruits, mixed with red onion, cilantro, and a hint of chilli, adds a burst of freshness and colour to your plate.

Ingredients

Units Scale
  1. 2 cups leftover cooked fish (flaked) (Note 1)
  2. 2 cups mashed potatoes (leftover or freshly mashed)
  3. ¼ cup finely chopped onion
  4. ¼ cup finely chopped celery
  5. ¼ cup finely chopped bell pepper (any colour)
  6. 2 cloves garlic, minced
  7. ¼ cup mayonnaise
  8. 1 tablespoon Dijon mustard
  9. 1 tablespoon lemon juice
  10. ½ teaspoon dried dill (or 1 tablespoon fresh dill, chopped)
  11. Salt and pepper to taste
  12. 2 eggs, beaten
  13. Vegetable oil for frying


Instructions

  1. Prepare the Leftover Fish:
    If your leftover fish has any bones or skin, make sure to remove them. Flake the fish into small pieces using a fork. Set it aside.
  2. Prepare the Vegetables:
    In a skillet, heat a bit of oil over medium heat. Add the finely chopped onion, celery, and bell pepper. Sauté for about 3-4 minutes, or until the vegetables are soft and the onions are translucent. Add the minced garlic and cook for another 30 seconds. Remove from heat and allow it to cool.
  3. Mix the Fish Cake Ingredients:
    In a large mixing bowl, combine the flaked fish, mashed potatoes, sautéed vegetables, mayonnaise, Dijon mustard, lemon juice, dried dill (or fresh dill), salt, and pepper. Mix everything thoroughly until the mixture is well combined.
  4. Form Fish Cakes:
    Take portions of the mixture and shape them into patties or cakes of your desired size. The size and thickness of the cakes are up to your preference. Place the formed fish cakes on a baking sheet lined with parchment paper.
  5. Heat the Oil:
    In a large non stick skillet, heat enough vegetable oil to cover the bottom of the pan over medium-high heat.
  6. Fry the Fish Cakes:
    Carefully place the fish cakes into the hot oil. Fry for about 3-4 minutes on each side, or until they are golden brown and crispy. Be gentle when flipping them to avoid breaking the cakes.
  7. Drain and Serve:
    Once the fish cakes are cooked and golden brown, transfer them to a plate lined with paper towels to drain any excess oil.
  8. Serve:
    Serve the fish cakes hot with your choice of dipping sauce, such as tartar sauce, aioli, or a squeeze of lemon.

Notes

  1. No leftover fish? Substitute:
    If you find yourself without leftover fish but still crave the delightful flavours of fish cakes, fret not! You can effortlessly substitute fresh fish with canned tuna to create equally delicious tuna cakes. Canned tuna offers a convenient alternative, making this recipe accessible anytime you desire a taste of the sea. Simply replace fish with 3 cans of tuna (drained).
