Ingredients
- 4, about 6 oz each rainbow trout fillets
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 cup all-purpose flour
- 4 tbsp unsalted butter
- 2 tbsp olive oil
- 2 tbsp, freshly squeezed lemon juice
- 2 tbsp, drained capers
- 2 tbsp, chopped fresh parsley
Instructions
- Step 1: Pat dry 4 rainbow trout 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.
- Step 2: Heat 2 tbsp olive oil and 2 tbsp unsalted butter in a large nonstick skillet over medium-high heat until butter foams.
- Step 3: Place fillets skin-side down in the skillet and cook for 4-5 minutes without moving, until the skin is crisp and golden brown. Carefully flip and cook the other side for 2-3 minutes until fish is opaque and flakes easily.
- Step 4: Remove fillets to a warm plate. Lower heat to medium, add remaining 2 tbsp butter, 2 tbsp lemon juice, and 2 tbsp drained capers to the skillet. Stir and cook for 1 minute until butter melts and sauce is fragrant.
- Step 5: Pour lemon-caper butter over the trout, garnish with 2 tbsp chopped fresh parsley, and serve immediately.
