Trout Patties

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Place a piece of aluminum foil large enough to wrap trout fillets into a 9x13-inch baking dish.

2 . Stage

Start the patties: Place trout fillets on the foil in the prepared pan; drizzle butter and lemon juice over trout. Fold the aluminum foil and seal the edges to enclose trout in a packet.

3 . Stage

Bake in the preheated oven until fish flakes easily with a fork, about 1 hour.

4 . Stage

Meanwhile, make the cocktail sauce: Mix ketchup and horseradish together in a small bowl until well combined. Refrigerate until needed.

5 . Stage

Finish the patties: Remove trout from the oven and let cool for 10 minutes. Flake fish into a large bowl. Add bread crumbs, onion, and celery; mix to combine.

6 . Stage

Whisk eggs, mayonnaise, and lemon-pepper seasoning together in a small bowl until blended. Add to trout mixture and mix until combined. Form mixture into 12 patties.

7 . Stage

Heat 1/4 inch oil in a deep skillet over medium heat. Working in batches, fry patties until deep golden brown, 4 to 5 minutes per side.

8 . Stage

Serve patties with reserved cocktail sauce.
