Instructions

1. Step 1: Pat dry 4 lake whitefish fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Lightly dredge each fillet in 1/4 cup all-purpose flour, shaking off excess.
2. Step 2: Heat 2 tbsp olive oil and 2 tbsp unsalted butter in a large nonstick skillet over medium-high heat until butter foams. Add the fillets and cook for 3-4 minutes per side until golden brown and cooked through (internal temperature 145°F).
3. Step 3: Remove fillets to a warm plate and tent loosely with foil. Reduce heat to medium and add remaining 2 tbsp unsalted butter and 2 minced garlic cloves to the skillet, stirring for 30 seconds until fragrant.
4. Step 4: Stir in 3 tbsp fresh lemon juice and 2 tbsp chopped fresh dill. Simmer the sauce for 1 minute until slightly thickened.
5. Step 5: Pour lemon-dill butter sauce over the fish fillets and garnish with 1 tbsp chopped parsley if desired. Serve immediately with simple sides to highlight this regional freshwater fish preparation.
