Ingredients

2 cups mashed potatoes 

2 teaspoons chopped fresh parsley 

Coarse salt and ground pepper 

1 cup all-purpose flour 

1 large egg 

1 1/2 cups fresh breadcrumbs 

Vegetable oil 

Preparation

In a large bowl, stir together mashed potatoes and parsley; season with salt and pepper. In a shallow bowl, place flour; season with salt and pepper. In another shallow bowl, whisk egg with 1 tablespoon water. In a third shallow bowl, place 1 1/2 cups breadcrumbs.

Form potato mixture into 3/4-by-2-inch logs. Roll in flour, shaking off excess, dip in egg wash, then roll in breadcrumbs to coat. In a heavy medium saucepan, heat 1 1/2 inches vegetable oil over medium-high until hot. In batches, fry croquettes until golden brown on all sides, about 2 minutes per batch, turing as needed. Drain on paper towels.
