Ingredients
- 4 fillets (6 oz each) catfish fillets
- 4 tbsp unsalted butter
- 1 tsp lemon zest
- 2 tbsp lemon juice
- 2 tbsp chopped fresh parsley
- 3 cloves minced fresh garlic
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
Instructions
- Step 1: Preheat your grill to medium-high heat (about 400°F). Brush 4 catfish fillets with 2 tbsp olive oil and season with 1 tsp salt and 1/2 tsp black pepper evenly on both sides.
- Step 2: In a small saucepan over low heat, melt 4 tbsp unsalted butter. Stir in 3 minced garlic cloves and cook for 1 minute until fragrant but not browned. Remove from heat and mix in 1 tsp lemon zest, 2 tbsp lemon juice, and 2 tbsp chopped fresh parsley.
- Step 3: Place the catfish fillets on the grill and cook for 4-5 minutes per side until the fish flakes easily with a fork and grill marks appear.
- Step 4: Remove the fillets from the grill and immediately spoon the lemon-garlic herb butter over the hot fish, allowing it to melt and infuse the fillets with flavor before serving.
