Cooking Steps

To start making your fish croquettes, grab those leftover potatoes and mash them until they're smooth.
Mix in the flaked fish and seasonings to create a flavorful mixture, then form it into small balls.
Chill these patties for a bit to make frying easier and to keep their shape.
Step 1. Prepare Yesterday's Leftover Potatoes

Leftover potatoes can be a delicious foundation for your fish croquettes. Start by peeling and mashing yesterday's potatoes until smooth, ensuring no lumps remain. Additionally, the dietary fiber in the potatoes can help with digestion, making this dish not only tasty but beneficial for your gut health. Freshly made mashed potatoes can also enhance the texture of your croquettes by providing better moisture retention during cooking.
In a mixing bowl, combine the mashed potatoes with flaked fish, like tilapia or cod, diced onions, minced garlic, and fresh parsley for extra flavor. Add an egg, breadcrumbs, lemon juice, salt, and pepper to bind everything together.
Shape the mixture into small patties, then coat them with a mixture of breadcrumbs, salt, and pepper for that perfect crispy exterior. Chill the patties in the refrigerator for about 30 minutes to help them hold their shape while cooking.
With a bit of culinary creativity, you're well on your way to tasty fish cakes! Additionally, incorporating high protein into your diet with fish croquettes can offer numerous health benefits.
Step 2. Mash the Leftover Potatoes

Start by peeling and mashing those leftover potatoes until they're perfectly smooth. Make sure there are no lumps, as this will improve the texture of your croquettes.
If your mashed potatoes seem too dry, add a splash of milk or a bit of butter to achieve a creamy consistency. Butter consumption can enhance the richness of your dish, but moderation is essential to maintain heart health. In fact, butter is a source of vitamins A, D, E, and K, which can contribute to a well-rounded diet. Next, mix in an egg to help bind the ingredients, ensuring the croquettes hold their form during frying.
For added flavor, fold in cooked and flaked fish, like cod or tilapia, into the mashed potatoes. This combination elevates the dish while introducing a delightful texture. Additionally, incorporating high-protein ingredients can enhance the nutritional value of your croquettes.
Now, you're ready to shape your mixture into patties, preparing them for frying and the delicious meal ahead!
Step 3. Add Seasonings to Mixture

As you prepare to enhance the flavor of your fish and potato mixture, consider adding a variety of seasonings that will elevate the overall taste.
Start by incorporating fresh herbs like parsley for a vibrant flavor boost. Then, add seasonings to the mixture, including salt, black pepper, and a pinch of cayenne for depth and a subtle kick.
A tablespoon of lemon juice brightens the flavors, balancing the richness of the fish and potatoes. For additional complexity, mix in minced garlic or sautéed onions for aromatic qualities.
Lastly, don't hesitate to experiment with spices like smoked paprika or dill, which can complement the fish and introduce unique flavor notes to your croquettes.
Step 4. Form Into Small Balls

Once you've combined your cooled mashed potatoes, flaked fish, egg, and seasonings into a cohesive mixture, it's time to form your croquettes.
Start by taking portions of the fish mixture and rolling them into small balls, about the size of large potatoes or golf balls. Make sure they're compact to prevent them from falling apart during cooking. If you'd like, you can create a small indentation in each ball for fillings.
Next, roll each formed ball in breadcrumbs to achieve a crispy exterior that enhances the texture once you fry them. This step not only adds flavor but also helps them firm up, making them easier to handle in the cooking process.
Step 5. Chill Before Frying

Chilling your fish croquette patties for at least 30 minutes is essential for achieving the best results. This cooling period allows the flavors to meld together, enhancing the overall taste.
As the patties chill, they firm up, making them easier to handle and fry without falling apart. To ensure they maintain their shape and develop a crispier exterior, arrange the patties spaced apart on the plate.
If you're making a larger batch of croquettes, consider freezing patties after the chilling process. This way, you can store them for future use and enjoy easy cooking later on.

While you might think that leftover mashed potatoes are just a side dish, they can transform into something extraordinary when combined with fish.
By using yesterday's mashed potatoes to create fish croquettes, you not only reduce food waste but also whip up a delicious, protein-rich dish. The blend of cooked fish, like cod or tilapia, and seasoned mashed potatoes results in a satisfying meal for everyone.
Forming the mixture into patties and frying them in avocado oil gives the croquettes a crispy texture that's hard to resist. Plus, customizing the recipe with fresh herbs or spices lets you tailor the flavors to your liking.
