  • 2 cloves garlic (minced)
  • 2 tablespoons fresh parsley (chopped)
  • 1 teaspoon Dijon mustard

Required Tools and Equipment

To craft perfectly crispy and flavorful tuna fish croquettes, you need the right tools and equipment. Ensuring you have everything ready will make the process smooth and efficient.

Mixing Bowls

You will need a large mixing bowl for combining the tuna mixture. A smaller bowl is also helpful for beating the eggs.

Cutting Board and Knife

A cutting board and a sharp knife are essential for finely chopping onions, garlic, and parsley.

Measuring Cups and Spoons

Accurate measurements are crucial. Use measuring cups for breadcrumbs and Parmesan cheese. Measuring spoons are ideal for Dijon mustard, black pepper, salt, lemon juice, and other spices or condiments.

Fork or Potato Masher

These tools help to break down the tuna into fine pieces, ensuring a consistent texture in your croquettes.

Baking Sheet

A baking sheet lined with parchment paper is necessary if you plan to bake your croquettes instead of frying them.

Frying Pan or Deep Fryer

For frying enthusiasts, a heavy-bottomed frying pan or deep fryer works best to achieve that golden-brown crust on your croquettes.

Spatula or Tongs

Use these tools to flip the croquettes gently while frying so they cook evenly on all sides without falling apart.

Paper Towels

Paper towels are handy for draining excess oil from fried croquettes before serving them piping hot with an optional dipping sauce on the side.

Gathering these tools beforehand, you’ll be well-prepared to create delicious tuna fish croquettes effortlessly.


In this section, you will learn how to prepare the tuna fish croquettes step by step. Follow these instructions carefully to achieve a perfect blend of flavors and textures.

Draining and Flaking Tuna

  1. Open the cans of tuna and drain the liquid thoroughly using a strainer.
  2. Transfer the drained tuna into a mixing bowl.
  3. Use a fork to flake the tuna into small pieces, ensuring there are no large chunks remaining.

Mixing Ingredients

  1. Add 1 cup of breadcrumbs, ½ cup of grated Parmesan cheese, ¼ cup of finely chopped onion, and 2 minced garlic cloves to the bowl with the flaked tuna.
  2. Incorporate 2 tablespoons of freshly chopped parsley for an aromatic touch.
  3. Stir in 1 tablespoon of Dijon mustard and season with ½ teaspoon of black pepper.
  4. Crack two eggs into the mixture to bind all ingredients together.
  5. Use your hands or a spatula to mix everything until well combined.


Now that you have your mixture ready, it’s time to form and cook the croquettes to perfection. Follow these steps for a crispy and delicious result.

Forming Croquettes

  1. Shape the Mixture: Take a small portion of the tuna mixture (about 2 tablespoons) and shape it into a ball or oval using your hands.
  2. Flatten Slightly: Gently flatten each ball to create a patty shape, ensuring they are even so they cook uniformly.
  3. Prepare for Frying: Place the formed croquettes on a plate lined with parchment paper, making sure they do not touch each other.

Frying Croquettes

  1. Heat Oil: Pour enough vegetable oil into a large skillet to cover the bottom (about ¼ inch). Heat over medium-high heat until shimmering but not smoking.
  2. Fry Croquettes: Carefully add several croquettes to the hot oil without overcrowding the pan. Fry each side for 3-4 minutes until golden brown and crispy.
  3. Drain Excess Oil: Use tongs or a slotted spoon to transfer fried croquettes onto a plate lined with paper towels to absorb excess oil.
  4. Repeat Process: Continue frying in batches until all croquettes are cooked, adjusting heat as necessary to prevent burning.


Now that your croquettes are perfectly cooked, it’s time to bring everything together for a delightful presentation.
