Step 1: Mix the Filling

In a large mixing bowl, combine the shredded potatoes and boiled, shredded chicken. Add the finely diced carrots, zucchini, and bell pepper. Stir in the finely chopped Serrano peppers for some heat. Season the mixture with salt, black pepper, garlic powder, onion powder, and chicken powder. Next, add the egg, cornstarch, fresh parsley, mozzarella, and Parmesan cheese. Mix everything thoroughly until the ingredients are well combined and sticky. The mixture should hold together when shaped.

Step 2: Prepare the Coating

In a separate bowl, mix the all-purpose flour with water to form a thick slurry (paste). This will act as the glue for the bread crumbs to stick to the croquettes. In another shallow bowl, pour the bread crumbs, which will give the croquettes their crispy coating.

Step 3: Shape the Croquettes

Using your hands, scoop out portions of the chicken and vegetable mixture and shape them into round or oval croquettes. Aim for consistency in size so they cook evenly. You should be able to make around 12-15 croquettes, depending on their size.

Step 4: Coat the Croquettes

Take each croquette and dip it into the flour slurry, ensuring it’s fully coated. Then, roll the croquette in the bread crumbs, pressing gently to make sure the crumbs stick well and create a uniform coating.

Step 5: Cook the Croquettes

• To Fry:
  Heat a good amount of oil in a large skillet or frying pan over medium-high heat. Once the oil is hot, carefully drop the croquettes into the pan. Fry for 2-3 minutes on each side, or until they are golden brown and crispy all over. Be sure not to overcrowd the pan—cook in batches if necessary.
• To Air Fry:
  For a healthier alternative, lightly spray the croquettes with cooking oil. Place them in the air fryer basket, ensuring they are not touching. Air fry at 400°F (200°C) for 10 minutes, flipping them halfway through for an even crisp. This method will give you a golden, crispy croquette with less oil.

Step 6: Serve & Enjoy

Once the croquettes are cooked to golden perfection, transfer them to a plate lined with paper towels to remove any excess oil. Serve them hot with your favorite dipping sauce like garlic aioli, marinara, or a spicy yogurt dip. These croquettes are perfect for any occasion—whether it’s a snack, an appetizer, or part of a meal.
