Ingredients
- 4 pieces, 6 oz each grouper fillets
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 6 tbsp, divided unsalted butter
- 2 tbsp finely minced shallots
- 1/3 cup dry white wine
- 2 tbsp fresh lemon juice
- 1 tbsp orange juice
- 6 cups baby spinach
- 3 cloves minced garlic
- 1 tsp leaves fresh thyme
- to taste salt
Instructions
- Step 1: Pat dry 4 grouper fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering.
- Step 2: Add fish fillets and sear for 4 minutes on the first side without moving until edges are golden and crust forms. Flip and cook for 3 more minutes until fish is opaque and flakes easily. Transfer fish to a warm plate.
- Step 3: In the same skillet, reduce heat to medium and add 2 tbsp minced shallots, sautéing for 1 minute until fragrant but not browned.
- Step 4: Pour in 1/3 cup dry white wine, scraping up browned bits, and simmer for 2 minutes until reduced by half.
- Step 5: Whisk in 4 tbsp cold unsalted butter one tablespoon at a time until sauce is smooth and glossy. Stir in 2 tbsp fresh lemon juice, 1 tbsp orange juice, and 1 tsp fresh thyme leaves. Keep sauce warm on low heat.
- Step 6: In a separate pan, melt 2 tbsp butter over medium heat. Add 3 cloves minced garlic and sauté for 30 seconds until fragrant.
- Step 7: Add 6 cups baby spinach and cook, stirring, until wilted and tender, about 3 minutes. Season with salt to taste.
- Step 8: Plate the grouper fillets, spoon generous amounts of citrus beurre blanc over the top, and serve with sautéed spinach on the side.
