Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil or cooking spray.
Peel the potatoes and slice them into 1/4-inch thick rounds. Boil them in salted water for 8-10 minutes until just tender. Drain and set aside.
Season the trout fillets with salt, pepper, garlic powder, and paprika. Drizzle with lemon juice and let sit while you prepare the remaining ingredients.
In a medium saucepan, melt butter over medium heat. Stir in the flour and cook for 1-2 minutes. Gradually whisk in the milk, stirring constantly to avoid lumps. Cook until the sauce thickens, about 3-5 minutes.
Remove the saucepan from heat and stir in shredded cheddar cheese. Add a pinch of salt and pepper to taste.
Layer half of the potato slices at the bottom of the prepared baking dish. Spread the baby spinach evenly over the potatoes.
Arrange the seasoned trout fillets on top of the spinach. Cover the fish with the remaining potato slices.
Pour the cheese sauce evenly over the casserole to cover the layers completely.
In a small bowl, mix the panko breadcrumbs with olive oil and chopped parsley, then sprinkle the mixture evenly on top of the casserole.
Bake the casserole in the preheated oven for 35-40 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Remove from the oven and let rest for 5-10 minutes before serving. Garnish with additional parsley if desired.
