Ingredients for Smoked trout croquettes
900 g medium russet potatoes, peeled, quartered
kosher salt
60 g unsalted butter, cut into pieces
28 g parmesan, finely grated
15 g chives, chopped
30 ml prepared horseradish
2.5 ml freshly ground black pepper
4 large eggs, lightly beaten, divided
225 g smoked trout, skin and any large pin bones removed, shredded
56 g low-moisture mozzarella, coarsely grated
240 g panko breadcrumbs
vegetable oil, for frying (about 1.5 litres)
lemon wedges, for serving
How to make Smoked trout croquettes
Cover the potatoes with cold salted water in a large pot.
Bring to the boil over medium heat, covered, then reduce the heat as needed to maintain a simmer until the potatoes are tender, about 20–30 minutes.
Drain the potatoes and transfer them to a large bowl.
Mash the warm potatoes with butter, then stir in the Parmesan, chives, horseradish, pepper, 2 beaten eggs, and ½ tsp salt until smooth.
Fold in the trout and mozzarella.
Form the potato mixture into approximately 60 round croquettes, each about 2 tablespoons in size.
Place the remaining 2 beaten eggs in a shallow bowl and the panko breadcrumbs in another shallow bowl.
Dip one croquette into the egg, allowing the excess to drip off, then roll it in the panko to coat. Transfer to a baking tray lined with parchment paper.
Repeat the coating process with the remaining croquettes.
Pour oil into a large pot to a depth of 10 cm and heat over medium-high until it sizzles when you toss in a pinch of panko or a deep-fry thermometer registers 180°C.
Working in batches, fry the croquettes, turning occasionally, until golden brown, about 4–5 minutes per batch.
Transfer the cooked croquettes to paper towels to drain and season with salt.
Serve immediately with lemon wedges alongside.
Do Ahead: Croquettes can be formed and coated up to 2 days in advance. Cover and chill on the baking tray.
