Pat the perch fillets completely dry using a paper towel.
Season both sides with salt and pepper.
Add the olive oil to a large skillet and place it over medium-high heat. Once hot, add the seasoned perch fillets skin-side down. Cook for 2-3 minutes. Gently slide a spatula under a fillet- if it lifts easily, flip it and cook for another 2-3 minutes. If it doesn’t release easily, continue cooking for another 30 seconds before checking again.
Remove the perch from the skillet and place on a serving dish. Add sliced lemon and dill and serve immediately.
Notes
Perch: Skin-on fillets are preferred. If using skinless fillets, cook for two minutes per side instead of three.
