Tuna Fish Croquettes


Tartare Sauce

  • 1/4 cup homemade mayonnaise
  • 1 tsp finely chopped fresh chives
  • 1 tsp fresh finely chopped fresh dill
  • 1 tsp finely chopped dill pickles
  • pinch cayenne pepper
  • pinch grated lemon zest


  • Combine the cold mashed potatoes, drained canned tuna, fresh chives, dill, dill pickles, garlic powder, onion powder, paprika and cayenne pepper into a medium sized bowl. Mix with a large spoon until well combined.
  • Form into 4 equally sized patties (each should weigh about 85g) and then carefully dip each patty in the flour, then in the eggs and finally in the breadcrumbs, reshaping them as needed.
  • Place the finished croquettes in a plate, cover loosely with plastic film and refrigerate for at least 2 hours, or up to overnight.
  • Preheat your oven to 400°F, brush a small baking sheet with olive oil and place the refrigerated croquettes on it, then delicately brush their tops with a little bit more olive oil.
  • Bake in the preheated oven for 25 minutes, or until golden and crispy, flipping once halfway through baking.
  • Meanwhile, make the tartare sauce by mixing all the ingredients together.
  • Serve the croquettes promptly, topped with a dollop of the tartare sauce and a sprig of fresh dill, if desired.
