Pat the walleye fillets dry with paper towels and season both sides with salt, black pepper, and paprika.

Heat olive oil in a skillet over medium-high heat. Once hot, add the walleye fillets and cook for about 4-5 minutes on each side until golden brown and cooked through.

In the same skillet, reduce heat to medium and add butter. Once melted, stir in lemon juice and cook for an additional minute.

Plate the walleye fillets and drizzle with the lemon butter sauce. Garnish with chopped parsley.
